    [0001] The present invention relates to a local unit and a method for remotely monitoring equipment maintenance. Many circumstances require that a technician intervene on equipment installed on a given site, which is different from the location of a manager of the equipment, and which may also be different from the professional location to which the technician is attached. The technician is then sent on a mission to the place of the equipment, at an agreed date, to perform the scheduled maintenance intervention. But in such circumstances of intervention on a remote site, there is the problem of verifying that the intervention on the site is actually performed with the agreed equipment and by the technician to whom the intervention mission was assigned . Such verification may be necessary in real time, while the intervention on the equipment is being performed, or later, for example when drawing up a report of the intervention. For the purposes of this description, the terms equipment, technician and maintenance mean the following: equipment: any installation or installation, whether indoor or outdoor, whatever its function. In particular, it may be individual or collective housing equipment, industrial equipment, urban equipment, transportation equipment, equipment with free or limited access, leisure facilities, including a green space or a municipal park. , etc .; technician: any agent who has the mission to intervene on the equipment; maintenance: any operation to be performed on the equipment, whatever the purpose of the operation, including troubleshooting, assistance, cleaning, maintenance of equipment or green space, etc. The invention can also be applied to the verification of the intervention of an agent at the residence of a resident, provided that the home is provided with a local unit according to the invention. The service of the agent who is the object of the intervention at home can then be an assistance to the person, a medical assistance, a childcare, the household, a service of kitchen or delivery, works, etc. However, an important field of application of the invention is the verification of an intervention by a maintenance technician on equipment that is installed in a collective housing, such as a building. For example, the equipment concerned may be a personal heating boiler, domestic hot water production equipment, designated by the acronym ECS, or a controlled mechanical ventilation equipment, or VMC. Furthermore, it is known, in particular patent FR 2 845 223, to install a local monitoring unit with equipment, such as an elevator, to provide an electronic maintenance book that is dedicated to this equipment. The electronic maintenance record contains information on the work that is performed during each maintenance intervention. But in addition, the local unit identifies the technician who is responsible for each maintenance intervention of the equipment, and record the start and end times of each intervention. The identification of the technician who is present near the equipment to carry out a maintenance operation is carried out by the technician himself. For this purpose, he enters an identification code by means of a keyboard whose local unit may be provided, or by means of a system for reading electronic keys, smart cards or magnetic cards, or by means of a biometric recognition system. From this situation, an object of the present invention is to further improve the local unit, to more safely ensure that a maintenance intervention that is provided on equipment is or has been performed by the identified technician, and according to the start and end times of the intervention that were collected. An additional object of the invention is to provide such increased safety with means, including individual means for the maintenance technician, which are simple and inexpensive. To achieve these or other goals, a first aspect of the invention provides a new local maintenance monitoring unit which is intended to be installed near equipment, to allow remote monitoring of maintenance of this equipment. This new local unit is adapted to capture, memorize, transmit or provide data relating to an intervention that is performed by a maintenance technician on mission on the equipment. It further comprises: a display matrix, which is arranged to display a two-dimensional code according to a code content that is variable; and a processor, which is arranged to update the code contents and to control the display matrix so that the two-dimensional code that is displayed conforms to the updated code content.
    [0002] Thus, an image of the displayed two-dimensional code, which is entered by the maintenance technician, for example with a portable communication terminal which this technician is provided with, constitutes a copy of at least a portion of the code content in accordance with a last bet. which is effective before the image is captured. The operation of capturing an image of the two-dimensional code - for example taking a photograph of this code - performed by the technician, in combination with changes in the code content that are not known a priori by the technician , ensures that the technician is really close to the equipment that is the object of the maintenance intervention. In particular, a simple transmission of identification and timestamping data that would be carried out remotely by a malicious technician, without going to the site of the equipment, is no longer sufficient to deceive a verification of the intervention, since the technician must provide in addition an image of the two-dimensional code such that this code is displayed by the local unit at the scheduled time for the maintenance intervention.
    [0003] In the context of the present invention, image acquisition is understood to mean any type of detection of a two-dimensional information of luminous intensity, in particular an instantaneous image capture, or "snapshot" in English and corresponding to the usual mode of photography. But the image capture can also be performed according to other modes of detecting the two-dimensional information of light intensity, such as a scanning by a row of detectors, commonly called scanner, for example a portable scanner.
    [0004] A display matrix is also understood to mean any display which is capable of displaying a two-dimensional pattern by producing variable values of light intensity at image points, or pixels, distributed in rows and columns. The identification of the technician can be carried out by the portable communication terminal of which the technician is provided, by associating with the image of the two-dimensional code which has been entered by the technician identification data such as a telephone number of the terminal or MSISDN for Mobile Station ISDN Number, an identification number of the terminal user that is stored in the SIM card, such as the IMSI for International Mobile Subscriber Identity, an identification number of the terminal itself. same, such as the IMEI for International Mobile Equipment Identity, an internet identifier, such as an email address, or an agreed personal code, etc. In particular, the communication terminal of which the technician is equipped may be a usual smartphone which comprises a camera, in which a dedicated application may possibly have been loaded. Geolocation coordinates of the communication terminal, corresponding to the moment when the image of the two-dimensional code is entered, can also be associated with the image by the communication terminal, and then transmitted with this image.
    [0005] The identification of the equipment can be provided by the image captured and transmitted. For example, equipment identification data may be displayed on the display matrix together with the two-dimensional code, next to it to appear in the image that is captured by the technician by means of its communication terminal.
    [0006] Alternatively, the identification data of the equipment may be included in the code content itself. A second aspect of the invention proposes a method of maintenance of equipment, by a technician on mission of intervention on this equipment, this method comprising the following steps: / 1 / install a local maintenance monitoring unit which is in accordance with the first aspect of the invention, close to the equipment; / 2 / by the local maintenance tracking unit: updating the code content, and displaying on the display matrix the two-dimensional code in accordance with the updated code content; / 3 / by the service technician when working on the equipment: enter at least one image of the two-dimensional code displayed with a portable communication terminal that this technician is equipped with; and / 4 / by a person other than the maintenance technician: check at least one element of the service technician's intervention based on the image of the two-dimensional code that has been entered, and possibly also from data that are associated with this captured image. The element of the technician intervention that is verified in step / 4 / comprises the identity between the code content of the two-dimensional code that has been captured by the technician during his intervention, with respect to a content reference code available to the person in charge of the verification independently of the image entered by the technician, and which corresponds to the scheduled time for the maintenance intervention. Other elements of the intervention that can also be checked in step / 4 / from the two-dimensional code captured in image can be: - timestamp data, which can correspond to the start and end times of the technician's intervention on the equipment. Such timestamp data may be associated by the maintenance technician's communication terminal with separate images of the two-dimensional code which are entered by the technician at the beginning and at the end of his intervention; geolocation data of the communication terminal which is used by the maintenance technician to capture the image (images) of the two-dimensional code, and which can be associated by the communication terminal with each image of the code two-dimensional which is captured; - identification data of the equipment subject to the maintenance intervention. Such data may be displayed by the local maintenance tracking unit in addition to the updated two-dimensional code, or be included in the code content itself. In advantageous embodiments of the invention, at least one of the following improvements can be implemented, separately or in combination of several of them: the two-dimensional code can be a QR-code, a Datamatrix, a Flashcode , or conform to any other information encoding mode in the form of a two-dimensional logo; the processor can be adapted to include in the code content at least one of the following elements: timestamp data of the last update of the code contents; a reference of the equipment which is the subject of the intervention by the service technician, comprising for example at least one of a model number, a serial number and an installation address of the equipment; equipment intervention data, such as power down or equipment shutdown; a characteristic of a state of operation or defect of the equipment; and a feature of a result of the service technician's intervention on the equipment; the processor may be adapted to include at least one of the preceding elements in encrypted form in the code content; the display matrix may be of the electronic ink type; The local maintenance monitoring unit can furthermore comprise communication means which are arranged to receive source data of code contents, and to transmit each source data of code content which is received by the processor to produce new code content from at least one of the received source data, and then to update the two-dimensional code that is displayed in accordance with the new product code content; the local maintenance monitoring unit may furthermore comprise means for detecting a movement thereof, and warning means which are arranged to be activated when a displacement of the local monitoring unit maintenance is detected by the displacement detection means; the local maintenance monitoring unit may furthermore comprise at least one sensor selected from a carbon monoxide sensor, a volatile organic compound sensor, a temperature sensor, a pressure sensor, a humidity sensor, and optionally further comprising a clock and at least one input for receiving status data. In this case, the processor can then be further arranged to perform at least one of the following actions: capture, store, transmit and display on the display matrix, in addition to the two-dimensional code, at least one of a result of measurement that was produced by one of the sensors, a time indication, and at least one status data that was received by the input of the local maintenance tracking unit; the local maintenance monitoring unit may furthermore comprise an energy source or a battery for supplying an operation of this local unit; and the image of the two-dimensional code which has been entered by the technician in step / 3 can be sent via a transmission network to at least one of a monitoring or control center at distance from maintenance technician intervention, equipment manager and equipment user. Preferably, this sending can be done from the portable communication terminal which the maintenance technician is provided with. An additional utility of a local maintenance monitoring unit which is in accordance with the invention may be assigned to a user of the equipment. Thus, an image of the two-dimensional code that is displayed on the local maintenance monitoring unit can be entered by the user of the equipment and then transmitted by this user to a company that is in charge of the maintenance of the equipment. equipment or a manager who is in charge of organizing the maintenance, to request a maintenance intervention. The two-dimensional code can thus serve to authenticate the request, and provide indications on the intervention that is requested when such indications are contained in the two-dimensional code or are captured in image at the same time as the two-dimensional code. In particular, the maintenance object equipment for which the invention is implemented may be a heating boiler, a domestic hot water production equipment, or a controlled mechanical ventilation equipment, each of these equipment being able to be collective or individual. Other features and advantages of the present invention will emerge in the following description of nonlimiting exemplary embodiments, with reference to the appended drawings, in which: FIG. 1 illustrates equipment in a maintenance situation, to which invention can be applied; FIG. 2 is a front view of a local maintenance monitoring unit, which is in accordance with the invention; and FIG. 3 illustrates steps of a maintenance method that implements the invention. For the sake of clarity, the dimensions of the elements which are represented in these figures do not correspond to real dimensions nor to actual dimension ratios. In addition, identical references which are indicated in different figures designate identical elements or which have identical functions. The invention is now described in detail for heating equipment, such as an individual heating boiler, for example in an apartment of a collective housing building. But it is understood that the invention can be applied to any other type of equipment and maintenance intervention or delivery, as indicated at the beginning of this description. In the figures, the references indicated have the meanings which are listed below: 1 local maintenance monitoring unit 2 display matrix 2a-2b display areas inside the display matrix 2 3 processor the local maintenance monitoring unit 1 4a-4e sensors of the local maintenance monitoring unit 1, which are optional for the invention 5 at least one external signal input, incorporated in the local maintenance monitoring unit 1, also optional 10 boiler forming the maintenance object equipment in this example 11 technician in charge of a maintenance intervention on the boiler 10 12 portable communication terminal fitted with the maintenance technician 11 13 data acquisition device picture provided with the communication terminal 12, for example a camera 100 remote monitoring or control center of the intervention of the maintenance technician 11 Throughout this description It is understood that the remote monitoring or control center 100 may be a server which is adapted to communicate in a controlled, automatic or semi-automatic manner with the local maintenance tracking unit 1. - 10 - local maintenance monitoring unit 1 is installed near or on the boiler 10. For example, it may have the form of a housing to hang near a control panel of the boiler 10. The local unit 1 comprises the display matrix 2, preferably on its anterior face, and encloses a processor 3 which is arranged to control a display content of the display matrix 2. Preferably, the display matrix 2 can be of the type in electronic ink, to cause energy consumption which is reduced. Processor 3 is programmed to produce display content from initial data. Such initial data has been called source data in the general part of this description. Other optional components of the local unit 1 may be the sensors 4a-4e, the external signal input 5, a memory, remote communication means, a battery or an autonomous energy source, an electronic clock internal means for detecting a displacement of the local unit 1 and warning means. These components have not all been shown in the figures, being individually well known to those skilled in the art. The sensors 4a-4e can be selected according to the type of the equipment concerned and the place of installation of this equipment. They may be selected to provide measurements that are useful for diagnosing a state of operation or defect of the equipment, or for preventing intervention conditions that could be hazardous to the technician 11. For example, it may be a sensor carbon monoxide, a volatile organic compound sensor, a temperature sensor, a pressure sensor, and a humidity sensor, etc. The external signal input 5 can be connected to the equipment, for example to receive equipment status data, especially in the form of binary data. Such state data may include operation enable signals or error signals.
    [0007] The operation of the processor 3 to generate successive updates of the display content can be autonomous, from an initial programming of the processor 3 and a recursive algorithm for example.
    [0008] Alternatively, and preferably, the initial data from which the processor 3 generates the display content can be received from the outside by the internal communication means to the local unit 1. These communication means, preferably without wire, can be of one of the known types, such as means of radio-broadcast, telephone, WIFI, or based on LoRaWAN protocol for "Long Range Wide Area Network". They then connect, by data transmission, the local maintenance monitoring unit 1 to the remote monitoring or control center 100, and possibly also to other interlocutors mentioned later in this description. The autonomous power source, optional, can be Peltier effect or photovoltaic cells, depending on the installation conditions of the equipment. The optional local unit 1 internal electronic clock can be used to provide time data that is used by the processor 3 to set the display content, or to trigger updates of the display content. including through a modification of the code content. The means for detecting a displacement of the local maintenance monitoring unit 1 have the function of detecting such a displacement that would not be expected. Indeed, by its function, the local unit 1 is intended to remain in place from its installation, close to the equipment to which it is dedicated, and such a move could be malicious or abnormal when it is not unforeseen. These displacement detection means may be constituted by an accelerometer internal to the local unit 1, or by any system for detecting a tear of the local unit 1 relative to its installation support. The local unit 1 then also comprises alert means which are activated by the displacement detection means. For example, the warning means may be a siren or means for transmitting an alert signal to the monitoring or remote control center 100, through the communication means of the local unit 1.
    [0009] The communication terminal 12 may be a smartphone, or internet access telephone, a tablet, or a portable professional terminal, which is provided with an image capture device, for example a photographic apparatus. This has an optics which is adapted to photograph the display matrix 2 of the local unit 1, by displaying the content which is displayed on the display matrix 2 in a sufficiently clear manner in photographs which are foreclosures. In order to implement the invention, at least one image of the display matrix 2 which is inputted by the technician 11 by means of its communication terminal 12 is transmitted to the remote control or monitoring center 100. According to one possibility which is not preferred, this transmission can be carried out in two steps, first from the terminal 12 to the local unit 1, and then from the latter to the monitoring or remote control center 100 if the local unit 1 is itself equipped with communication means. However, in preferred embodiments of the invention, the communication terminal 12 makes it possible to transmit the image that is inputted to the remote monitoring or control center 100, directly, that is to say independently of the local unit 1. For this, the communication terminal 12 may be provided with a SIM card and transmission means which are adapted to connect to an external data transmission network, such as a telephone network or an internet network. The local unit 1 is adapted to generate a display content that is variable, and update the display matrix 2 according to each new display content that is generated. According to the invention, the display content comprises a variable two-dimensional code and optionally additional data. For example, the two-dimensional code is displayed in the area 2a of the display matrix, and the additional data can be displayed in the area 2b. The display areas 2a and 2b are preferably adjacent, to appear together in images that are captured by the communication terminal 12. According to the invention, the two-dimensional code is variable according to successive updates, to ensure that the technician It is close to the equipment that is the subject of maintenance, within the scheduled time for the maintenance intervention. The two-dimensional code can be of one of the following types: QR-code, Datamatrix or Flashcode, in a non-limiting way. Its content, called code content, is preferably calculated by the processor 3 from initial data that can be either initially recorded within the local unit 1, or generated by an algorithm within the unit. local 1, or received by the local unit 1 through its own means of communication, for example from the monitoring center or remote control 100. The control of the actual presence of the technician 11 with the in the expected time range is provided by the fact that the initial data which is responsible for each new update of the code content which is displayed on the display matrix 2, in the form of the two-dimensional code, is unknown prior to the technician 11 and is not accessible otherwise than by visualization or photography of the display matrix 2. Optionally, the code content may comprise not only variable components q These are deduced from the initial data, and which ensure the modification of the code content at each new update, but also additional elements relating to the identification of the equipment, or relating to the circumstances of the maintenance intervention. For example, the code content may also contain timestamp data of its last update, which will identify the actual update when the display matrix 2 is photographed, a reference of the equipment, such as a model number, a serial number, an equipment installation address, or geo-location coordinates of the equipment, a data of the intervention on the equipment, such as the reason for the maintenance intervention, a characteristic of a state of operation or defect of the equipment, for example obtained from the state data that can be received by the input 5, or possibly also a characteristic of a Result of the maintenance technician's intervention on the equipment, such as a restoration validation, an interruption of operation or electrical supply of the equipment for the purpose of the intervention maintenance, etc. When geo-location coordinates of the equipment are used, these can be obtained from the external transmission network which can be connected to the local maintenance monitoring unit 1. According to an improvement of the invention, these elements can be crypted by the processor 3 before being inserted into the code contents. The elements that can be displayed in the display area 2b of the display matrix 2, can also be the identification elements of the equipment, but also measurement results that are produced by at least one of the 4a-4e sensors, or some of the equipment status data that can be received by the input 5. These elements can be displayed in the zone 2b in non-encoded form, to be directly readable by the technician 11 during his maintenance intervention. In known manner, when a communication terminal transmits data via an external transmission network, identification data of the transmitting terminal, or identification of the user of this transmitting terminal, are simultaneously transmitted. . For the present invention, these identification data of the communication terminal 12 or the technician 11, which are attached to each image which is inputted from the display matrix 2 and then sent to the remote control or monitoring center 100, serves identifying the technician 11 who performs the maintenance intervention. These identification data may include the telephone number of the communication terminal 12, or MSISDN, a technician identification number which is stored in the SIM card, or IMSI, an identification number of the terminal itself, or IMEI, an internet identifier, such as an e-mail address, an agreed personal code, etc. In addition, the time and date of transmission, in this case the transmission of each photograph of the display matrix 2 by the communication terminal 12, are attached to the useful content that is transmitted.
    [0010] Thus, two photographs of the display matrix 2 that are entered and transmitted respectively at the beginning and at the end of the maintenance intervention that is performed by the technician 11, provide the monitoring center or remote control 100 hours. beginning and end of the intervention. In addition, the transmission of each photograph of the display matrix 2 from the communication terminal 12 makes it possible to geo-locate the latter by means of the external transmission network which is used. This geolocation makes it possible to further control the actual presence of the technician on the site of the equipment at the moments of transmission of the photographs. It is also common to use a geolocation receiver which can be incorporated in the communication terminal 12, for example a GPS receiver, for "Global Positioning System", to associate with each photograph that is inputted by means of this terminal. , geographical coordinates of the place of photography. Such geographical coordinates can be transmitted with each photograph by the communication terminal 12 to the monitoring or remote control center 100. To transmit the photographs of the display matrix 2 that are entered by the technician 11, the communication terminal 12 can host a dedicated application. This can automatically designate the recipient (s) of each photograph sent, including the remote control or monitoring center 100, but also optionally a manager of the equipment or the building in which this equipment is installed, or a user of the equipment, such as a resident of the building. In Figure 3, which illustrates a particular mode of use of a local maintenance monitoring unit 1 as described above, the steps are divided into three columns according to the device that performs each step. The steps in the left column (Si, S5, S7 and S11) can be executed by the tracking or remote control center 100, those in the center column (S2, S3, S8 and S9) are executed by the center. local maintenance monitoring unit 1, and those in the right column (S4, S6 and S10) are performed by the technician 11 at the intervention site by means of its communication terminal 12.
    [0011] In a first step (step S1), the tracking or remote control center 100 can send initial data for new code content to the local maintenance tracking unit 1. The processor 3 of the latter calculates then the new code content from the initial data received, and possibly also from additional data such as equipment identification data, possibly encrypted. The processor 3 then updates the two-dimensional code according to the new computed code content (step S2), and commands to display the thus updated two-dimensional code on the display matrix 2 (step S3). The steps S1 to S3 that constitute a two-dimensional code update sequence can be performed periodically, or from a command that is triggered by the tracking or remote control center 100, or from a trigger which is caused by the technician 11 when he arrives at the local maintenance monitoring unit 1. For example, the local maintenance monitoring unit 1 may comprise a push button to be operated by the service technician 11 for trigger a renewal of the two-dimensional code that is displayed. Such action to be performed by the technician 11 can be an additional guarantee of its actual presence on the site of the equipment object of the maintenance intervention. Alternatively, the update of the two-dimensional code can be triggered automatically by a human presence detector whose local unit 1 can be provided, with each new human presence that is detected near the local unit 1. Just before to begin his maintenance intervention, the technician 11 photographs the two-dimensional code that is displayed on the local maintenance tracking unit 1 (step S4), and transmits this photograph to the monitoring or remote control center 100 by means of his terminal This photograph allows an agent at the remote control or monitoring center 100 to check the code content that appears in the photograph (step S5). For this, the two-dimensional code that is read on the received photograph can be decoded by the agent of the remote monitoring or control center 100, and then compared to the initial data that was transmitted to the step Si. Alternatively, a content of code, possibly partial, can be calculated at the monitoring or remote control center 100 from the initial data of the step Si, independently of the local maintenance tracking unit 1, and then this code content thus calculated can to be compared to that which appears on the photograph received. Simultaneously, the data that is associated by the communication terminal 12 with the photograph during its transmission, indicate the time of the beginning of the maintenance intervention. The code contents, the identification of the equipment and these transmission data constitute the elements of verification of the maintenance intervention. When the tracking or remote control center 100 is a server, the verification step S5 can be performed automatically, and the server can issue an alert message when the comparison of the code content that appears in the photograph, with the initial data or with the recalculated code content, reveals a difference. The warning message can be addressed, for example, to an occupant of the apartment in which the boiler is located which is the object of the maintenance intervention. Step S6 is the maintenance intervention of the technician 11 on the equipment, for example the operations of troubleshooting and restarting the equipment. Finally, the steps S7 to S11 are a repetition of the steps S1 to S5, respectively, which is carried out by the technician 11 at the end of his maintenance intervention. This repetition allows the monitoring center or remote control 100 to know the end time of the intervention, with the assurance that the technician 11 is still on the site of the equipment at that time. However, the steps S7 to S9 are optional, the steps S10 and S11 being sufficient to transmit the proof of the real presence of the technician 11 on the site of the equipment until the time of transmission of the new photograph which is entered in step S10. An additional use of the local maintenance monitoring unit 1 by the technician 11 concerns dangerous situations that may occur during the maintenance intervention, during step S6. Indeed, an image of the displayed two-dimensional code that is entered by the technician 11 can be transmitted with an alarm triggered by means of an isolated worker alarm device (DATI). This image can be used to authenticate the alert, and can provide information on the circumstances of the danger, useful for dispatching assistance or relief. These useful indications which are contained in the transmitted image may comprise in particular the identification elements of the equipment, and measurement results which are produced by the sensors 4a-4e, and which appear in the image transmitted at the same time. than the two-dimensional code. Finally, another auxiliary use of the local maintenance monitoring unit 1 may be dedicated to a user of the equipment. For example, when the equipment is down or malfunctioning, a user of the equipment, for example a resident of the building in which the boiler 10 is installed, can take a photograph of the two-dimensional code that is displayed on the screen. local maintenance monitoring unit 1, using his own smartphone, then send this photograph to a company in charge of maintenance of the equipment or to a manager in charge of organizing the maintenance, to request an intervention of maintenance. The two-dimensional code which is photographed then transmitted by the user makes it possible to authenticate the intervention request. It can also provide useful indications on the reason for the intervention that is requested, and possibly also to remotely perform a first diagnosis of the malfunction of the equipment.
    [0012] One skilled in the art will understand that multiple variants of the invention may be used, with respect to the embodiments that have been described in detail above, while retaining at least some of the advantages mentioned. Among these benefits, the main one is to provide assurance that an identified technician is actually on the site of a maintenance intervention, by collecting the start and end times of his actual on-site presence. The method of the invention is particularly robust for this purpose, with respect to cheating intentions on the part of an unscrupulous technician. In particular, in possible variants of the invention, the source data of a new code content can be generated in the local maintenance tracking unit 1, for example by the processor 3, and then transmitted to the monitoring center. or remote control 100 by the communication means of the local unit 1. Then, the tracking or remote control center 100 can still perform the verification of the code content according to the image that is captured and then transmitted by the service technician according to step S5. Possibly also, source data that has been generated in the local maintenance tracking unit 1 may be transmitted to the remote monitoring or control center 100 at the end of the display period of the code content. corresponding. In this way, the source data can not be captured unintentionally during a transmission thereof between the remote control or monitoring center 100 and the local unit 1, as long as the corresponding code content is still displayed. The verification step S5 can be performed as soon as the code content has been updated from a new source data. The control efficiency provided by the invention can be further increased as well. Finally, the way to generate each source-data at the origin of a new code content can be any: recursive algorithm, random or pseudo-random generation, etc.
