    Motion detector device
    5 Technical sector of the invention
    The motion detecting device of the present invention is one that allows the movement and presence of people in the vicinity of the device to be detected, particularly those used in lighting control systems.
    10 Background of the invention
    Motion detecting devices comprising infrared PIR sensors to detect the movement and presence of people in the vicinity of the device are known, 15 being adapted for installation in walls and ceilings from where they have a good field of vision.
    However, these types of devices are not suitable for placement near very busy environments, since it is difficult to determine if the detection is due to a person close to the sensor or due to a remote detection in the busy environment, which may cause a false positive
    One solution is to use a device that is provided with a more directive sensor, however, this solution does not allow to adjust the field of vision of the sensor if necessary.
    25 To solve this problem, devices are known that allow the movement of the sensor in relation to a set of lenses to regulate its field of vision, such as the device described in US5757004.
    30 However, this type of device needs to move the sensor, so that it can suffer wear due to a continuous movement of the sensor that can end up misaligning it.
    Also known are sensors arranged in a hemispherical housing comprising a curtain in the form of dome portions that can be superimposed and cover parts of the sensor's field of vision, such as that described in WO201448381.


    However, this type of device does not allow the curtain to be arranged so that the sensor can detect at 360 ° since there will always be a portion of the hemispherical housing covered by the curtains in the form of overlapping dome portions.
    5 Devices are also known comprising interior curtains whose rotation isadjustable, and depending on its rotation cover the field of vision to a greater or lesser extentof the sensor, such as the devices described in documents US6987267 and DE4023341.Also known are devices comprising interior curtains, not visible from theoutside, which can descend in front of the sensor, as described in
    WO2011148231 and EP1847822; and devices that have internal cross fins between the sensors, such as those described in patent document DE102010014282
    However, these devices do not allow to determine the configuration of the sensor's field of vision without close inspection of the device, since the curtains are hidden and not
    15 are visible by an operator. As this type of device is usually installed on ceilings and at heights to have a good field of vision, it is difficult for an operator to access a close inspection of the device.
    It is therefore an objective of the present invention to disclose a device that allows
    20 easily and intuitively know remotely the configuration of the field of vision of the proximity sensor, without requiring a detailed inspection of the device or having to disassemble it, while allowing to easily adjust the field of vision of the motion sensor .
    25 Another objective is to present an alternative to known motion detecting devices.
    Explanation of the invention.
    The motion detecting device of the present invention is one of those comprising a motion sensor that has a field of vision and allows the detection of people in said field of vision.
    In essence, the device is characterized in that it comprises one or more fins adapted for
    35 adopt a hidden extreme position in which they do not cover the field of vision of the motion sensor and an extended extreme position in which they protrude from the device and cover


    part of the field of vision of the motion sensor, so that the field of vision of the sensor can be reduced to limit the field of vision of the sensor and cover areas with less movement, excluding areas that are not of interest to monitor, for example because they have a large influx such as corridors or spaces that are too crowded and that would activate the motion sensor of the motion detector device too often or even continuously, which may for example be linked to the lighting of a light. Therefore, if the device was devoid of fins, it could happen that the light was continuously on due to the passage of people through a space close to the sensor too crowded. Advantageously, by actuating the fins of the device, the field of vision of the motion sensor is achieved is reduced in those directions in which, depending on its length, the fins cover the field of vision of the sensor, in addition to being able to determine an operator limiting the field of vision of the remote motion sensor, simply observing whether or not the fins are extended and being able to assess whether the field of vision could still be enlarged or reduced depending on how extended the fins are in the device by simple remote visual inspection.
    It is also known that the fin (s) move linearly between the hidden extreme position and the extended extreme position so that the fins can move vertically, that is, in a direction normal to the surface or ceiling on which it is installed the device, and concealment requiring a gap of reduced size, for example smaller than if the fins were hinged hinges.
    It is also known that the device comprises a support that houses the fin (s), the support comprising a rail for each fin through which each fin moves linearly between the hidden extreme position and the extended extended position covering part of the field of view of the motion sensor, allowing the support and guides to be formed into a single piece.
    It is also known that each fin is provided with a guide, as a pair of facing hooks adapted to hug and engage a respective rail and allow the vertical movement of the fin along the rail, allowing the fin to hold the rail together and you can move along it.
    It is also known that the guide is disposed at the upper end of each fin, thus acting as a stop of the extended extreme position.


    It is disclosed that the lower end of each fin is beveled so as not to obstruct the field of vision of the motion sensor in the hidden extreme position.
    It is disclosed that the lower end of each fin has a groove to facilitate its5 displacement by inserting an operator in said slot the nail, screwdriver or similar to modeof support for the displacement of the fin.
    It is also known that, the device comprising a support housing the fin (s), the support has a recess adjacent to the groove of each fin to favor access to the groove when the fin is in its hidden extreme position.
    It is also known that the motion sensor is connected to an electronic block attachable to the support, each rail forming a stop for the coupling of said electronic block in the support, which in turn forms a stop of the movement of the fins, of
    15 so that the movement of the fins is limited between the ends of the rail, the support and the electronic block acting as a stopper of the fins.
    It is also known that the upper end of each fin has a profile adapted to be coupled against the connection of the motion sensor and the electronic block, that is, with the base of the motion sensor, so that the fin is properly retained in its extreme hidden position.
    It is disclosed that the fin (s) have a curved shape, surrounding part of the motion sensor, which preferably will have a circular or spherical cap shape to cover, ideally, a cone-shaped field of view of the sensor with 360 degree coverage around Of the device. Preferably the curvature of each fin is greater than 90 degrees, so that with two fins it is allowed to limit more than 180 degrees, which allows two ends of the sensor's field of vision to be covered, which is sufficient for most applications, for example to limit the field of vision to a passenger compartment arranged between two parallel aisles
    30 for which there is an influx of people. It is also envisioned that more fins with a smaller angle can be arranged or even that all the fins have a smaller angle.
    It is also known that the fins are arranged symmetrically with respect to the motion sensor, so that it is possible to cover two opposite areas of the field of vision of the motion sensor.


    It is also known that the motion sensor is a PIR technology sensor, which does not require an additional source of illumination, but determines movement or presence from the infrared radiation emitted by moving bodies, for example of people.
    It is also known that the device further comprises a lighting sensor, which can be used to determine the degree of ambient lighting and adjust the luminaire brightness level to a predefined setpoint level or, for example, not to activate a luminaire if There is enough natural light. It is also envisaged that the device has an LED indicating the result of the detection of the motion sensor, usually being on when the motion sensor detects movement in its resulting field of vision and off when the motion sensor does not detect movement in said field Of vision.
    It is envisioned that the device comprises a DALI communications interface that allows the result of the motion sensor detection to be communicated. Naturally, it is also provided that the device is provided, alternatively or in addition to other types of interfaces known in the state of the art, such as a relay output that allows lighting and switching off of luminaires, or an analog output that allows a voltage to be established. variable depending on the lighting regulation of the luminaires, for example an analog output between 1 and 10V that also allows controlling the regulation of the luminaires.
    Brief description of the drawings
    To complement the description that is being made and in order to facilitate the understanding of the characteristics of the invention, a set of drawings is attached to the present specification in which, for illustrative and non-limiting purposes, the following has been represented:
    Fig. 1 shows a front view of the device of the present invention;Fig. 2 shows the device of the present invention in correlative fitting position;Fig. 3 shows a view of section AA of the device of Fig. 1Fig. 4a presents a top view of the fins of the device of the present invention;Fig. 4b shows a view of the section BB of the fins of Fig. 4Fig. 5 shows a view of the section of the device of Fig. 3 with a flap in position

    Detailed description of the drawings
    As can be seen in Fig. 1, the motion detector device 1 of the presentinvention comprises a support 2 adapted to be placed on a ceiling or the like providedof a motion sensor 3 which will preferably be an infrared PIR sensor, that is,a passive infrared sensor. Motion sensor 3 allows to detect the movement ofpeople or other bodies that emit heat within their field of vision V, so alsoIt could be considered that motion sensor 3 is a presence sensor.
    It is noted that the lens of the motion sensor 3 has a circular or cap shapespherical, so that it can capture infrared radiation evenly throughout itsfield of view V, approximately conical, around the motion sensor
    3. However, in some situations it is desirable that the field of vision can be limited to prevent movement from being detected at certain specific angles or sectors. This application is especially important in environments such as corridors in open-plan offices, where it is desired to differentiate the movement detection of people from the corridor from those who are working in adjacent areas.
    Advantageously, the device 1 is provided with one or more fins 4 that can be hidden or with an adjustable height in said support 2 to protrude from the support and cover part of the field of vision V of the motion sensor 3 depending on its extension outside the support
    2. As will be seen below, the greater the extent of each fin, that is, the more protruding from the support 2, the greater the field of view V of the motion sensor 3 in the direction covered by the fin 4 and consequently a reduced field of view V 'will be obtained in that direction.
    As can also be seen in Fig. 1, the device 1 is provided with a lighting sensor 10 to detect if the level of visible light illumination in the environment exceeds -710


    predetermined threshold, and a led 11 that illuminates to inform if the motion sensor 3 detects movement in its field of view V. The led 11 is especially useful for regulating the height of the fins 4 to adjust the field of view V of the sensor , so as to avoid detecting movement at angles where it should be covered by a fin 4. Both the motion sensor 3 and the lighting sensor 10 are expected to be connected via a DALI communications interface of the device 1 for indicating its status to a control device connected to said DALI communications interface, so that an automatic control of on and off of luminaires connected to said control device 1 can be performed depending on the occupation status of the area and regulate the level of brightness indicated by the device 1 of the present invention to adapt it to an optimum light setpoint for the work area. It is also envisioned that the automatic control of lighting on and off connected to the control device 1 can be carried out with other types of interfaces known in the state of the art, such as a relay output that allows the lighting of the luminaires on and off, or an analog output that allows to establish a variable voltage depending on the lighting regulation of the luminaires, for example an analog output between 1 and 10V that also allows controlling the regulation of the luminaires, that is, their level of lighting intensity.
    It is also observed in Fig. 1 that the two fins 4 of the device 1 have a curved shape, the curvature of each fin 4 being greater than 90 degrees, so that they can a sector around the motion sensor 3 greater than 180 degrees, is that is, allowing the field of vision to be limited to an angle greater than 50% of the angle that forms the field of vision around the motion sensor 3. Since usually the sectors in which the field of vision should be reduced are extreme, the two fins 4 of the device 1 are arranged symmetrically to the motion sensor 3, each fin being adapted to limit the field of view V at an opposite end of the device 1.
    In Fig. 1 the mounted device 1 is illustrated, in which the cover 2 and the different electronic components are mounted in their operative position. As can be seen in Fig. 2, the device 1 is formed on the one hand by the cover 2 and on the other hand by an electronic block 9 as a box in which the different sensors are connected and which in Fig. 2 It is illustrated in correlative position of lace. As can be seen, the motion sensor 3 is connected to the electronic block 9, the electronic block 9 being attachable to the support 2. In a known manner, it is provided that the cover 2 and the electronic block 9 also have a set of tabs and grooves that allow the firm coupling to mount the device 1, alternatively they may have other firm coupling means, such as


    A set of screws. For a better understanding of the invention, the electronic block 9 has been represented in a simplified manner, representing only the motion sensor 3. Advantageously, being the support 2 and the electronic block 9 separable parts, it is envisioned that electronic blocks 9 mounted on known supports can be reused to form the device 1 of the present invention, replacing its conventional support devoid of fins by the support 2 of the device 1 of the present invention incorporating fins 4. This functionality also allows to change the level of coverage of the field of vision V of the fins 4 simply by replacing the support 2 of the device. Thus, if for the device shown in Fig. 1 it was necessary to adjust the field of view V of the motion sensor 3 throughout its viewing angle, the support 2 provided with two fins 4 covering about 120 degrees could be replaced by a support 2 with three fins 4 each covering 120 degrees, whereby 360 degrees of the field of view V of the motion sensor 3 could be adjusted. Naturally, it is also contemplated that the support 2 has a single fin 4 with the necessary curvature, as well as that the fin (s) 4 can be straight
    or have the form that is most convenient to cover the field of vision V of the motion sensor 3.
    In order to be able to appreciate the detail of the operation of the fins 4 of the device 1, several figures will now be presented in which section A-A of Fig. 1 is shown with different positions of the fins 4.
    Fig. 3 shows section AA of Fig. 1 in which it can be seen that the motion sensor 3 is connected to the electronic block 9, and the electronic block 9 is coupled to the support 2, so that the motion sensor 3 is housed in a central hole through the support 2. Similarly, although it is not visible in the section AA represented, the lighting sensor 10, led 11 and button 12 would be connected to the electronic block 9 and would be housed in respective holes of the support, so that the mounted device 1 presents the configuration previously illustrated in Fig. 1. The support 2 is advantageously adapted for installation in a ceiling or recess that allows the support 2 to fit, so that once installed it will act effectively as a support for the electronic block 9.
    It is seen in Fig. 3 that the support 2 of the device comprises a rail 5 for each fin 4, as a rod, through which the fin 4 can move and adjust in height between a hidden end position A in the support in which it does not cover field of vision V of the motion sensor 3 and an extended extreme position B that covers part of the field of


    vision V of motion sensor 3, forming a limited field of vision V ’in the direction covered by fin 4 as will be seen below.
    Each flap 4 is provided with a guide 6 adapted to engage a respective rail 5 and allow the displacement of the flap 4 along the rail 5. It is envisioned that the rail 5 can be smooth or have some roughness, jagged or protruding, so that it facilitates to establish in a stable way the position of the fin 4 without it varying due to vibrations or its own weight. For securing the flap 4 to the rail 5, the upper end of each flap 4 has a guide 6 suitable for embracing the rail 5 with a certain adjustment and thus allowing the position of the flap 4 to be established by moving the guide 6 in lane 5.
    The movement of each fin 4 is limited superiorly by the electronic block 9 that is supported on the rail 5, so that the guide 6 is prevented from moving beyond the electronic block 9, which acts as an upper stop. In addition, the upper end of each fin has a profile 13 adapted to be coupled against the motion sensor 3 and the electronic block 9, so that in the hidden end position A, the fin is supported by its entire upper end against the block electronic 9, getting a stable extreme position.
    The displacement of each fin 4 is also limited inferiorly by the base of the support 2, since when the guide 6 is arranged at the upper end of each fin 4, the guide 6 bumps inferiorly against the base of the support in the extended extended position B , as will be illustrated below.
    To facilitate the movement of each fin 4, each fin 4 is advantageously provided with a groove 7 at its lower end, which allows, after inserting a nail or a small tool such as a screwdriver, its displacement and removal of the support can be facilitated 2, especially when the fin 4 is in the hidden end position A illustrated in Fig. 3. To facilitate access of a nail or small tool, when the fin 4 is in the hidden end position A, the support 2 it has a recess 8 adjacent to the groove 7 of each fin 4. Also to facilitate access to the groove 7 of each fin 4, the lower end of each fin 4 is chamfered, allowing the fin 4 to protrude further from its lower outer end without interrupting the field of vision V of the motion sensor 3 when it is in the hidden extreme position A. It is envisaged that both the fins 4 and the support 2 are preferably made of polypropylene or.


    Figs. 4a and 4b illustrate in detail the fins 4 previously presented the device 1. As can be seen in Fig. 4a, which is a top view of the two fins 4, these have a curved shape and have the upper profile 13. Also its upper end has the guide 6 adapted to fit in a rail 5 and allow the displacement of the fin 4 between the hidden end position A and the extended end position B. In Fig. 4b, which is a view of section BB of Fig. 4a, the arrangement of the guides 6, arranged at the upper end of each fin 4, as well as its upper profile 13 and the bevel and groove 7 of its lower end can be observed.
    Fig. 5 shows the section AA of the device 1 previously presented in Fig. 3, in which the two fins 4 have been extended protruding from the support 2, it can be seen that one of the fins 4 has adopted its extended extreme position B while the other has been arranged in an intermediate position, so that a limited field of view V 'is formed that will not be symmetrical, this position can be useful if you only want to slightly limit the field of view V at one end of the device 1 and limit itself to a greater extent on the other end. If it is desired to obtain a limited field of vision V ’of the motion sensor 3 that is maximum, both fins 4 must be arranged in their extended extreme position B as illustrated in Fig. 6.
    Fig. 7 shows the device installed for operation on a roof, in which its two fins have the extended extreme position B, in the same way as previously illustrated in Fig. 6, and Fig. 8 presents a example of an enclosure in which the device of Fig. 7 would be installed.
    By way of example, Fig. 8 shows the device 1 of the present invention installed in an enclosure between two aisles P in which there is a large influx of people, represented by arrows F, but it is not desired that this influx of people is detected by the motion sensor 3. Therefore, the device 1 has been installed so that the fins 4, in the direction of the x-axis, allow to establish a limited field of vision V 'that does not reach the aisles, while the separation between the fins 4, in the direction of the x-axis, maintains the original field of view V of the motion sensor 3. Generally, it is provided that when the device 1 is installed at 2.5 meters high, the field of view V cover a diameter on the ground of 6 meters, while the limited field of vision V 'when the fins 4 are in the extended extreme position B cover a diameter on the ground of 1.2 meters, thus avoiding false positives due to areas high concurrency They do not want to be considered for the motion detection of the motion sensor 3.
