    [0001] The present invention relates to the management of updates in a remote metering installation. It relates more particularly to a method of managing the software update of remote-reading terminals of a remote-reading installation. A remote reading installation conventionally comprises several remote-reading terminals, for example smart meters for water or gas, which can perform a consumption metering but also transmit information from different readings (temperature, pollution, etc.). . The data transmitted by the remote polling terminals, pass through access points, usually by radiofrequency link. These access points, then allow the feedback of information at a remote management system management server, to which they are connected via a telecommunications network, for example a network wired or wireless, GPRS or other type. The remote-control terminals are installed on the water, gas or other networks requiring counting and measurements, most of the time for a long period, generally of the order of ten years. To ensure their permanent operation, even in the absence of electric current, these remote-control terminals operate with electric accumulators. Also, an important problem is the limitation of their electrical consumption. To update the embedded software in these remote polling terminals, it is known to proceed remotely, transmitting, via the access points, the update data. However, since the radiofrequency communication means incorporated in the remote-reading terminals are relatively energy-consuming, it is necessary to plan the transmission of these update data. Also, we know, from patent document EP2661050, a method for updating remote-access terminals all associated with the same access point ("data collector" in English), which transmits an update announcement. to the terminals, indicating when the update data will be transmitted by the access point. Thus, the terminals activate their radiofrequency communication means only at the instant indicated in the announcement. In a remote polling system, comprising a plurality of remote polling terminals, and a plurality of access points, the updates are generally transmitted at the same time by all the access points, which creates a strong signal. congestion of the radio spectrum and increases the risk of bad reception of update data by remote polling terminals. In areas of high concentration of remote-calling terminals, for example in large cities, this risk is significantly increased, because of the possible superposition of several quasi-simultaneous broadcasts on the same frequency bands. Also, there is a need to optimize the management of updates in a remote polling facility. In order to solve this problem, the present invention provides a method of managing a software update of a plurality of remote polling terminals to be updated in a remote metering facility comprising a plurality of points. access, the plurality of access points being adapted to communicate by radio frequency link with the plurality of remote access terminals to update, and being adapted to communicate with a management server of the tele-lift installation via a telecommunication network, each remote terminal of the plurality of remote polling terminals to be updated being associated with an access point of the plurality of access points for transmitting data. remote data transmission to the management server, the method being characterized in that it comprises steps of: (a) transmitting a receive data planning message 30 e update to the plurality of remote polling terminals to be updated via their associated access points, the planning message including a start time of broadcasting the update data; (b) selecting a set of access points from the plurality of access points to limit the number of access points used to broadcast the update data, while allowing reception of the data of updated by the plurality of remote polling terminals to be updated; (c) sending update data by the selected set of access points at the start of broadcast time. 1 o The remote-reading terminals of the plurality of remote-reading terminals may be, without limitation, water meters, gas meters, electricity meters, but also monitoring devices of sensors for example to monitor sensors for flow rates, temperature, humidity, levels, velocity, acoustic sensors, conductivity, turbidity, pH, and H2S sensors. These remote-reading terminals may also be, in a non-limiting manner, sensor monitoring devices in housing and tertiary activities, for example monitoring intrusion detection sensors, smoke, carbon monoxide. These remote metering terminals may also, without limitation, include or be devices for controlling actuators, for example to close valves in case of leak detection. Advantageously, the selection made in step (b) of the set of broadcast access points makes it possible to reduce the size of the radio spectrum 25 during the transmission of the update data, which also allows the transmission of the update data. reducing the risk of poor reception of update data by remote polling terminals. In particular, the selection step (b) comprises transmitting a notification message of the selection to each access point of the set of access points selected, the notification message comprising the start time of diffusion. Advantageously, during step (a) of transmission of the update data reception planning message, each terminal of the plurality of remote polling terminals to be updated transmits an acknowledgment message to its destination. associated access point, to confirm the schedule for receiving the update data at the start of broadcast time. In particular, the step (c) of sending update data by 1 o the set of access points selected is performed several consecutive times. Advantageously, the step (a) of transmitting the update data reception planning message is carried out, for each remote terminal of the plurality of remote-calling terminals (T1-T9) 15 to update, following the reception, by its associated access point, of remote reading data transmitted by the remote-reading terminal. The present invention proposes, in addition, a remote metering installation comprising: a management server; A plurality of remote polling terminals to be updated; A plurality of access points; the plurality of access points being adapted to communicate by radiofrequency link with the plurality of remote metering terminals to be updated, and being adapted to communicate with the management server of the remote metering installation by the a telecommunication network, each remote terminal of the plurality of remote polling terminals to be updated being associated with an access point of the plurality of access points for transmitting telecommunication data. reporting to the management server, the remote poll facility being characterized in that: the management server is adapted to control the transmission of an update data reception scheduling message to the plurality of television terminals -relève to update, through their associated access points, the planning message including a start time of dissemination of the update data; the management server being adapted to select a set of access points from the plurality of access points so as to limit the number of access points used to broadcast the update data, while allowing the reception of the access points; update data by the plurality of remote polling terminals to be updated; the set of access points selected by the management server being adapted to transmit the update data at the start of broadcast time.
    [0002] Other features and advantages of the invention will appear on reading the following description of two particular embodiments of the invention, given by way of indication but not limitation, with reference to the accompanying drawings in which: FIG. 1 represents an example of a remote metering installation according to a first embodiment of the invention; FIG. 2 represents an example of a remote reading installation according to a second embodiment of the invention; With reference to FIG. 1, a remote metering installation comprises a remote management installation management server 1.
    [0003] This management server 1 communicates via a telecommunication network with 3 access points P1, P2, P3 of the installation. The management server 1, for example, comprises a network card for communicating with the access points P1 to P3, a microprocessor and an internal memory. These access points P1 to P3 comprise, for example, a radiofrequency transmission-reception card and a radio antenna for communicating with the remote access terminals T1 to Tg of the installation, a network card for communicating via the radio network. telecommunication with the management server 1, a microprocessor and an internal memory. The remote metering installation furthermore comprises a plurality of remote data terminals T1 to Tg, in this embodiment 9 remote data terminals T1 to Tg. These remote-reading terminals T1 to Tg are, for example , gas consumption metering terminals, installed in gas supply circuits of individual dwellings. The remote-lift terminals T1 to Tg comprise, for example, an electric battery, a microprocessor, an internal memory, radiofrequency communication means and means for counting the consumption of gas. The remote-reading terminals T1 to Tg communicate, via their radio-frequency communication means, with the access points P1 to P3 via a radio-frequency link. The radiofrequency communication means of the remote-tilt terminals T1-Tg are, from a general point of view, turned off outside the polling data transmission periods, in order to save the electric battery. Also it is not possible for the access points P1 to P3 to transmit data to the remote terminals T1 to Tg, when they have extinguished their radio frequency communication means. Because of the transmission range limits of the radiofrequency communication means of the remote tilt terminals T1 to Tg and the transmission range limits of the radio frequency communication means of the access points Pi to P3, each television terminal T1-Tg retrieval of the remote metering installation is associated with an access point P1 to P3, said associated access point. All of the 25 remote-lift terminals T1 to Tg associated with the same access point P1 to P3 form a group of remote polling terminals. The association of a dial-up terminal T1 to Tg to an access point Pi to P3 can be performed during the initialization of the remote-calling terminal T1 to Tg. Preferably, the association can be effected by the election, by the management server 1, of the access point P1 to P3 receiving the best signal from the remote terminal T1 to Tg being initialized. For this purpose, the access points P1 to P3 transmit to the management server 1 an information message as soon as they receive the signal from a new remote terminal T1 to Tg. receiving the signal from the remote terminal T1 to Tg being initialized. Also, after a short waiting period, of the order of a few seconds, the management server 1 elects the access point receiving the best signals from the remote terminal T1 to Tg in progress initialization, and then transmits to the access point Pi to P3 elected, an association message. The association message informs the access point P1 to P3 elected, that the remote terminal T1 to Tg being initialized joins the group of remote polling terminals associated with it. This association message is immediately relayed by the access point P1 to P3 elected to the remote terminal T1 to Tg being initialized. Also, the management server 1, stores in its memory, the association between the remote terminal T1 to Tg and its access point P1 to P3associated, and stores, in addition, the list of access points P1 to P3 having informed of the receipt of the signal of the remote terminal T1 to Tg being initialized. The management server 1 can, at the end of this initialization phase, define transmission range areas Zpi to Zp3 of the access points P1 to P3.
    [0004] In this embodiment, a first group T1 to T3 of remote polling terminals is associated by the management server 1 with the first access point P1, because of their presence in the transmission range area Zpi of the point P1 access. This association enables the first group of remote terminal T1 to T3 to communicate by radiofrequency link with their associated access point P1, to transmit remote data, which may be measurement data and / or data. counting, for example gas consumption. These measurement and counting data are then transmitted by the associated access point Pi to the management server 1 of the remote metering installation. This association is performed for each remote-reporting terminal exclusively; also a remote terminal T1 to Tg always transmits its information to the same access point Pi to P3 associated.
    [0005] Nevertheless, a remote polling terminal may receive data from another access point P1 to P3 of the remote polling installation. An access point P1 to P3 communicates with a plurality of remote data terminals T1 to Tg, according to the instructions transmitted by the management server 1, and non-exclusively with respect to the choice of remote data terminals T1 to Tg communicating. Similarly, a second group T4 to T6 of remote polling terminals is associated with a second access point P2 having a transmission range area Zp2, and a third group T7 at Tg of remote polling terminals is associated to a third access point P3 having a transmission range area Zp3. The remote polling terminal T4 is included in the transmission range area Zpi of the access point P1 and in the transmission range area Zp2 of the access point P2. However, it is associated with the access point P2, in accordance with what is explained above for the election of the associated access point during the initialization of the remote-reading terminal T4. Similarly, the remote-reading terminals T5 and T6 are included in the transmission range area Zp2 of the access point P2 and in the transmission range area Zp3 of the access point P3. However, they are associated with the access point P2, according to what is explained above for the election of the associated access point during the initialization of the remote terminal T4. The management server 1 receives update data for remote polling terminals, provided by the manufacturer of the remote polling terminals to be updated. The management server 1 determines to which dial-up terminals T1 to Tg these update data are intended. To do this, the management server 1 has in its internal memory information relating to each remote lift terminal T1 to Tg of the remote polling installation. In particular, the management server 1 stores for each remote terminal T1 to Tg, the manufacturer of the terminal, the model and the current version of the internal software, also called firmware or "firmware" in English. This data will allow the management server 1 to list the list of remote terminals T1 to Tg, affected by the update. In this exemplary embodiment, the set of remote-reading terminals T1 to Tg is concerned with the software update; this is called T1-Tg dial-up terminals to be updated. It is obvious to those skilled in the art to reduce the list of terminals of the installation to a list of terminals only concerned by the update, for example, by ignoring the possible remote terminals T1 to Tg not concerned. by the update. The management server 1 will then establish the list of access points Pi to P3 associated with remote terminals T1 to Tg to update. In this example, the list of access points associated with the remote access terminals T1 to Tg corresponds to the set of access points P1 to P3 of the installation. The management server 1 will then transmit a message to all access points P1 to P3 associated with remote terminals T1 to Tg to update. This message instructs the associated access points P1 to P3 to transmit an update data receive scheduling message to the remote access terminals T1 to Tg to be updated, this message including a predetermined time of start of transmission. dissemination of update data. The start time of broadcast update data may be encapsulated in the scheduling message as a timestamp value, also called a "timestamp" in English. This predetermined time indicates to the remote terminal when it should turn on its radio frequency communication means, to receive the update data. In order for the system to operate coherently, the management server 1 ensures that the access points Pi to P3 and the remote terminal T1 to Tg of the installation are synchronized on the same schedule. which is a thing well known to those skilled in the art. Due to the extinction of the radiofrequency communication means of the remote-reading terminals T1 to Tg, outside the times when they have to transmit their data for remote reading, it is not possible for the access points 30 P1 to P3, immediately transmitting the update data reception planning message to the remote terminals T1 to Tg to be updated. Also, the access points P1 to P3, waiting to receive data from a remote tele-lift terminal T1 to Tg, to transmit the planning message, if the terminal is concerned by the update. day. In fact, the remote-reading terminals T1 to Tg keep their radio-frequency communication means on for a short period following a remote data transmission, in order to receive a message from an access point P1 to P3. Advantageously, this short waiting period of a message can range from 1 second to 60 seconds. At the end of this short waiting period, the remote-calling terminals T1 to Tg turn off their radio-frequency communication means until the next transmission of remote data. When a dial-up terminal T1 to Tg to be updated transmits data for remote reading to its access point P1 to P3 associated, the latter transmits it, after receiving the data of remote reading, the planning message initially transmitted by the management server 1, thus taking advantage of the short waiting period following the transmission of remote reading data, where the radiofrequency communication means of the tele-lift terminal T1 to Tg 20 remain active. The remote-reading terminal T1 to Tg then transmits an acknowledgment message to its associated access point P1 to P3, to confirm that the scheduling message has been taken into account and to confirm the wait, at the instant start of broadcast, receiving update data. In other words, the acknowledgment message confirms the schedule for receiving update data at the start of broadcast. The access point P1 to P3 then transmits a message to the management server 1 to indicate that the planning message has indeed been transmitted to the remote terminal T1 to Tg.
    [0006] The management server 1, then proceeds to the selection of a set of access points, called broadcast access points, from the plurality of access points P1 to P3. By set is meant at least one access point P1 to P3. The selected broadcast access points will be used to transmit the update data to said predetermined start time of broadcast update data. The server will select these broadcast access points from the plurality of access points P1 to P3 of the installation, as a function of the remote access terminals T1 to Tg to be updated, and according to the range areas. transmission of access points P1 to P3. Advantageously, the management server 1, selects the smallest number of access points from the plurality of access points P1 to P3 making it possible to transmit the updates to all the remote-access terminals T1 to Tg to update. In this exemplary embodiment, the broadcast access points selected to broadcast the update data correspond to both access points P1 and P3, excluding the access point P2, because Zpi and Zp3 emissions, respectively associated with the access points P1 and P3, cover and reach all the remote terminals T1 to Tg to update. This selection limits the number of broadcast access points P1 to P3 used to simultaneously transmit the update data. This advantageously makes it possible to reduce the size of the radio spectrum during the transmission of update data. The broadcast access points P1 and P3 then receive from the management server 1 a notification message informing them that they have been selected as broadcast access points used to broadcast the update data. . The notification message includes the start time of the update data broadcast, as a timestamp. Then the management server 1 transmits the update data to the selected access points P1 and P3, so that they can, at the predetermined broadcast start time, transmit in turn the update data. day to the remote terminals T1 to Tg to update.
    [0007] To ensure good reception of this data, the selected broadcast access points P1 and P3 transmit the update data to the remote terminal T1 to Tg to be updated several times in succession. Advantageously, the transmission is carried out 5 consecutive times. This makes it possible to correct the updating data that may have been corrupted during radio frequency transmissions. Once the update data has been received, each remote terminal T1 to Tg to be updated, having received the updates, extinguishes its radiofrequency communication means, checks the integrity of the update data 1 o received and proceeds to their writing in internal memory. In a second exemplary embodiment, with reference to FIG. 2, the remote metering installation comprises six dial-up terminals T1 to T6 to be updated and three access points P1 to P3. A first group of remote data terminals T1 to T3 is associated, in a manner equivalent to that performed in the exemplary embodiment with reference to FIG. 2, to the first access point P1, because of their presence in the transmission range zone Zpi of the access point P1. This association allows the first group T1 to T3 to communicate by radio frequency link with their associated access point P1, to transmit data remote reading. A second group of remote polling terminals T4 to T6 is associated with a second access point P3. Also, according to this exemplary embodiment, a P2 access point of the installation is associated with no T1 remote terminal at T6de the installation, despite the fact that the remote terminals T1 to T6 are included in its Zp2 transmit range area. Nevertheless, the management server 1 selects, during the selection of the access points used to broadcast the update data, the access point P2 which is not associated with any remote access terminal T1 to T6. , to transmit the update data. Indeed, because all the remote-reading terminals T1 to T6 are included in the transmission range area Zp2 of the terminal P2, the congestion of the radio spectrum is advantageously reduced during the transmission of the data. update since the updating data can be transmitted simultaneously to all of the remote data terminals T1 to T6 to be updated, by selecting a limited number of access points, in this case a only P2 access point. It appears in this embodiment that a broadcast access point P2 may be an access point not associated with any terminal T1 to T6 of the installation. It also appears that an associated access point Pi or P3 to remote access terminals T4 to T6 to be updated may not be selected as a broadcast access point to broadcast the data of update.
