Description

The invention relates to an installation for monitoring and / or calling by terminal. The invention will be more particularly described with respect to a use in a place of sale, without being limited thereto. The installation of the invention could of course be used in other places, public or private, which require monitoring and / or a human response, in particular by the arrival of at least one person, during a call. via a terminal. By way of no limitation, the monitoring facility and / or call terminal terminal of the invention can also be used in a retirement home, or a temporary location such as a temporary stand of a fair, any place requiring surveillance or the call of persons for a specific action (opening a door, advice, delivery, reception etc ...). Today, the surveillance of stores against theft is mainly through cameras, electronic anti-theft associated with the over-the-counter items, anti-theft detection gates arranged at the entrances and exits of the stores and cooperating by radio frequencies with anti-theft devices. , as well as people (watchmen) some of whom monitor in a technical room (monitoring station) the display screens of the store associated with cameras, and others are arranged near the porticoes if they start to ring in case of detection. The cameras can be fixed or mobile by being controlled from the monitoring station. If a theft occurs or a malfunction is detected in a store, the alerts put in place involve the security guards who go on site and communicate with the monitoring station. The security guards can, if necessary, request the movement of a camera to film the incident. However, between the moment of detection 5 and that for which the watchman warns the monitoring station, there may be a certain period of time during which the incident unfortunately could not be filmed because the camera was not focused on the location of the incident. Furthermore, the arrangement of the surveillance cameras and detection gantries 10 must be thought at the time of the design and layout of the store, because requiring electrical cable passages. Any subsequent addition of control elements generates significant costs related to the work for the passage of cables, routing and make the store again aesthetic.

The object of the invention is therefore to propose a monitoring and / or call terminal calling system which does not have the drawbacks of the prior art in order to be implemented quickly, easily and at a lower cost. even later to the design of a building already incorporating a surveillance system, particularly this facility using radio frequency data transmission technology. According to the invention, the monitoring and / or call terminal facility comprises a device for triggering a signal, radiofrequency communication means, said communication means being at least associated with the triggering device. of the signal, and is characterized in that - the communication means transmit according to the ZigBee communication protocol, and in that the installation comprises at least one initial transmitting device of a ZigBee communication information, - interface means between the device for triggering a signal and the device transmitting an item of information, preferably the interface means comprising at least one switch, such as a dry contact, at least one final receiving device of the information sent by the transmitting device, said receiving device communicating by ZigBee communication, and 10 - a plurality of transmission and reception relays by common ZigBee nication to transmit information when the transmitting device and the receiving device are too far apart. Thus, the communication for transmitting the information is not wired, removing the electrical cables that otherwise would have been routed between the triggering devices and the information receiving devices. Advantageously, the communication is via the ZigBee protocol making the installation much less expensive and much simpler technically than contactless communication and short distance by Bluetooth. ZigBee communication provides low power consumption. Indeed, the emission of a wave is effective only when the triggering device generates a signal that will control the actuation of the transmitting device, and the wave will be cut on receipt of the information by the final receiving device. For this purpose, the final receiving device is also a transmitting device and the initial transmitting device is also a receiving device. In addition, because of the mesh of ZigBee transmitters / receivers, regardless of the location within the 3038114 4 trigger device store and the final receiver device on the other hand which may be a person mobile in the store, the information will necessarily be received, and allow a quick response. For the purposes of the invention, the term "call terminal" means a device for which a user performs only a single action to initiate a call such as pressing or pressing a button, or selecting a data item on a touch screen. For example, a call terminal is a device with a push button type of manual call button, or with a touch type display screen. A calling station excludes the telephone or any device that would require writing or dictating a message. The installation is therefore simple to implement, the user for a call having only one button to operate. According to one characteristic, the initial transmitter device comprises a ZigBee transmitter / receiver, the interface means and electronic processing means which, by operating interface means, generate coded information to be transmitted, preferably the initial transmitter device is associated with the triggering device of a signal, being in the immediate vicinity, or housed in the body of said triggering device.

The final receiver device comprises a ZigBee transmitter / receiver, electronic means for processing the information received and for returning a response information, a touch-sensitive means for validating the reception of the information intended to be actuated by a user. natural person (such as a push button), and an interface between the touch means and the processing means such as a switch of the dry contact type.

By way of examples, the device for triggering a signal is a detection device, such as an antitheft gantry type anti-theft detection device, a presence detector, a camera associated with detection means or image processing apparatus, a smoke detector, an alarm, or a call terminal comprising a housing having at least one touch button actuation means, and / or a touch-type display screen . Advantageously, the interface means associated with the initial transmitter device and / or the final receiver device of the installation comprises a plurality of switches connected to electronic processing means which have in memory a plurality of coded information intended to be emitted when the switches are actuated, each switch corresponding to a specific information. Thus, a switch corresponds to information, for example for a store, information consists of: triggering such portico 20 antitheft, alarm such cash, triggering such smoke detector, wait customer in front of such showcase, customer call in such aisle , opening of such a window, etc. The initial transmitter device and / or the final receiver device is preferably in the form of a housing when a physical person 25 must actuate a button to transmit information (for a call for example, or to validate information received and read) and comprises several pushbuttons, each button having an identification for the physical person who will press the button, and an associated switch 3038114 6 which, connected to the processing means of said device engenders the actuation of the button, the transmission of specific information. The coded information includes data that is adapted to each use (nature of the event to be communicated, identification of the location linked to the event, identification of the receiving devices intended exclusively for receiving the information, etc. ). The signal processing means comprise a data library, in particular programmable before the installation is put into operation or reprogrammable later, the data of the library associating with at least one given switch of the transmitting or receiving device, a given piece of information. to transmit, preferably the library comprising several directories such as the nature of the trigger event to be communicated, the identification of the location related to the event (identification of the detection device for which a signal has been detected), identification of the receiving devices intended exclusively for receiving the information, response to be sent following the received message. When the final receiving device is intended for a natural person, such as an employee in a store, it comprises a display screen 20 on which is intended to display the information transmitted from the initial sending device, the information presented in the form of a text message to read, especially corresponding to the exact nature of the action that the person must perform. Advantageously, the installation comprises a plurality of receiving devices including at least one camera provided with processing means which on receipt of the transmitted information, control the camera so that the latter films the signal triggering device.

The final receiving device may be any automated technical device operable upon receipt of the information. The invention also relates to a method of monitoring and / or calling by terminal comprising at least one step of triggering a signal, at least one step of radiofrequency data communication, characterized in that it uses the ZigBee communication protocol to transmit data from the signal processing, and the triggering step is related to the monitoring of a location and / or a call and in that it further comprises the following steps: - processing of the signal detected during the triggering step to generate information to be communicated associated with this signal, - transmitting the information by ZigBee communication, - receiving the information and processing the information, the information 15 could be relayed by transmitters / receivers under ZigBee protocol. According to the monitoring and / or calling method of the invention, when the information is received and processed, it is displayed in the form of a message to be read and / or triggers the command / system operation. 20 automated techniques. In response to the information received, the method includes a step of validating the information received by transmitting a response information stopping the initial ZigBee transmission. Finally, the invention relates to a use of the installation or the method of the invention for surveillance in a place of sale such as a shop, in a temporary place, in a public place, or a private place .

For example, in a store, the installation will advantageously be used to detect the wait of a customer in front of a shop window, for a call from a customer at a place in the store, a call from a cashier, a call from the central office, the call of the director, the call of a watchman, detect any alarm in the store (anti-theft door, smoke detector), remotely open a door and that by a selected person, etc. The present invention is now described by way of purely illustrative and non-limiting examples of the scope of the invention, and from the attached illustrations, in which: FIGS. examples of use of the monitoring and / or call installation of the invention; Figure 4 is a schematic diagram of the installation of the invention; FIG. 5 illustrates a mesh of transmitters / receivers in the installation. The installation 1 of the invention intended for the monitoring and / or the calling terminal call and illustrated in FIGS. 1 to 3 corresponds to its use in a magazine according to three application examples, respectively. Figure 1 illustrates the surveillance in a store by the presence of at least one anti-theft gate 20. Figure 2 illustrates an emergency call terminal 21 at a box 10 in a store.

Figure 3 illustrates the monitoring of a showcase 11 in a store. In these three configurations, the installation comprises a surveillance camera, respectively 12A, 12B, 12C, and the remote presence 3038114 9 of at least one person P intended to move to the place to be monitored or called during the triggering of an alert signal. The camera is optional but nevertheless preferred. The installation of FIG. 2 comprises a call terminal at a cash register of the store. Similar to the use of a calling station, the installation could be used to call a vendor within a store radius to require the arrival of a person (a seller). FIG. 4 schematically illustrates the installation of the invention in the form of a diagram and comprises: at least one triggering device 2 for an alert signal, such as the anti-theft portico 20 (FIG. 1) or the terminal of FIG. 21 (Figure 2) near the body 10, or a motion detector 22 (Figure 3) level of the window 11; electronic processing means 3, such as a microcontroller, the processing means 3 being advantageously connected to the triggering device 2 by a switch 30 of the dry contact type; at least one transmitting device 4 of information communicating via the ZigBee protocol, the transmitting device 4 being connected to the processing means 3 for transmitting the information coded by said means; a final receiving device 5 of the information communicating via the ZigBee protocol; a plurality of ZigBee communication transmitters and transmitters 6A, 6C, 6D, etc. constituting information transmission interfaces between the transmitter device 4 and the receiver device 5 which are generally too far apart from each other for ZigBee protocol communication. The information received is advantageously in the form of a text message readable by a natural person.

Preferably, the transmitter device 4 is also a ZigBee communication receiver device and the receiver device 5 is also a ZigBee communication transmitter device. In this way, when the receiving device 5 receives the information, it is possible to validate (for example by the natural person having received the message corresponding to the information) the fact that the information has been received by sending back information coded validation transmitter device 4 which will be able to receive it. The triggering device 2 of a warning signal emits a signal which controls the closing of the switch 30 which puts the data processing means 3 into operation. The signal is for example: the triggering of the anti-theft gantry 20 who detected the proximity or the passage of a lock placed on a sales item; the actuation of an alarm element such as a pushbutton 22 of the call terminal 21, this terminal being in the form of a conventional pushbutton housing; - Detecting a presence for a continuous period of time by the presence / motion detector 22 associated with the camera 12C, the detector may or may not be integrated into the housing of the camera 25 according to the configuration of places.

In the case of a call terminal, this is for example as described above a terminal in the form of a housing having at least one push button. As a variant, the terminal is, for example, without being any more restrictive, a display screen such as a touch screen 5 on which choices are displayed, one of which must be selected by touching the user wishing to call someone, a seller in the chosen application example. The switch 30 and the processing means 3 having been put on alert as well as the transmitter device 4 are preferably associated with the trigger device 2 of the signal by being housed in the body / housing of said trigger device 2. The means Processing 3 process the received signal to transform it into coded information adapted to be transmitted by the transmitting device 4. This information is configured by the processing means 3 to be able to be transmitted via the Zigbee communication protocol. Moreover, depending on the type of signal received, the information transmitted will be different. Therefore, the processing means 3 are also able to establish specific information based on the received signal. Thus, at a given signal will correspond specific information. For example, in the example of the anti-theft gantry, the information will consist of a message relating to the triggering of an anti-theft gantry; for the calling station, the message to be generated will be related to an emergency call at the cash register, while for the continuous presence of a customer in front of a window, the message will relate to the presence of a customer in front of a 25 showcase. In addition, the information may be associated with the identification of the trigger device 2, so that the message to be delivered is advantageously associated with the identification of the lock of a given location of the store, or of a specific cash register number in the store, or a specific shop window. Thus, the signal processing means 3 comprise a data library which lists different types of signal, the list of trigger devices 2 of the store associated with an identification, a plurality of information each corresponding to a message to be transmitted. The transmitted information is preferably received in the form of a text message. Depending on the triggering device and the type of information to be transmitted, the information is coded. The coding of the information may be manual by a series of binary switches on an electronic card which depending on the position of each switch will correspond to specific information. The coding can also be programmed via software that will be momentarily connected to the electronic processing means 3 and made prior to the start of operation of the installation.

Coding by manual or computer programming may also be updated later. Computer programming can be done remotely. The receiving or receiving end device 5 operates according to ZigBee communication. It comprises a receiver, electronic processing means and in some cases a display screen for displaying in the form of a text message the information received and processed by the electronic means. The text message is intended to be read by a natural person. The receiver device 5 can be in various forms. It may be a system with a display screen 50 when the message is intended to be read. It is then preferably of reduced size to be compact and portable. It can for example be a pager, commonly referred to as "pager" anglicism. It could also constitute a mobile phone type ordiphone, commonly also called in the language popularized by anglicism "smartphone", provided that it has a Zigbee transceiver and associated processing means. The receiver device 5 may further consist of a ZigBee receiver associated with a controllable / operable, information receiving, and automated technical system, such as for example the cameras 12A-12C. Advantageously, these cameras 12A to 12C are equipped with a ZigBee transmitter / receiver associated with a dry contact. Upon receipt of the information by the camera's ZigBee receiver, this causes switching of the contact to generate a control command managed by electronic means specific to the camera, the control command being for example the rotation of the camera to the trigger device 2 of the signal to punctually film said device including an event to trigger a signal. The camera control is independent of ZigBee protocol. These are programmable processing means according to need.

In this example, the associated electronic processing means programmatically store in memory the orientation coordinates of the camera lens combined with the prior identification of the triggering devices, to automatically turn to the scanner device. trigger having generated the signal and therefore the information associated with said identifiable device. It should be noted that the cameras can also be ZigBee transceiver relays for relaying information to the final receiver device 5. In order to make the installation efficient, it is necessary to arrange a plurality of relay relays in the premises. transmission and reception 6A to 6D which constitute ZigBee nodes, due to the communication by ZigBee at short distance, so as to relay the information from the transmitter device 3, then from one node to another to transmit and 5. Figure 5 illustrates the mesh of ZigBee nodes 6A to 6D, or more, in the installation. The operation of the installation is now described with regard to the three examples of use of the respective figures 1 to 3. With reference to FIG. 1, when the anti-theft gantry 20 sounds because it detects the presence of a transmitter lock disposed on an article, it also emits an alert signal which switches the switch 30 and actuates the processing means 3 associated with the transmitter device ZigBee 4 of the gantry. In turn, the ZigBee transmitter device 4 transmits two warning information (arrows Z illustrated in dashed lines in the figure) on the one hand to the receiver device 5 (here schematized in the form of a "pader" carried by a watchman P of the store), and on the other hand to the camera 12A which is in this embodiment a receiver device ZigBee protocol to automatically direct the camera lens on the trigger device and film for a period of time the scene, at least until the arrival of the vigil. The watchman during this time received the information in the form of a readable text message indicating that such trigger device, here gantry 20, has tripped. When the ZigBee receiver of the camera 12A receives the coded information dedicated to the camera and expressly recognized by the receiver of the camera, it also generates by switching a switch, a validation of the reception of the information causing a return transmission (arrow V1) of a response information to the receiver device 4 of the gantry 20 which can then stop transmitting the initial information to the camera. At the same time, the security officer P having received on his "pager" the information which is dedicated to him, warning him of an incident at the gantry, 10 validates the reception of the information via a button 51 on his pager which switches a switch , generating the emission by ZigBee (arrow V2) of a response information dedicated to the receiver device 4 of the gantry 20 which then stops transmitting the initial information for the watch. The security guard physically goes to the scene (arrow V3).

With regard to FIG. 2, if the cashier encounters an incident, she can immediately call urgently by pressing the button 22 of the trigger device 21. This switches the interface switch 30 between the button 22 and the processing means 3 in the housing of the device 21. The processing means 3 configure two separate and coded information respectively dedicated to the camera 12B and to a person P such as the security guard in charge of the store. The transmitter device ZigBee channel 4 transmits the two coded information. When the ZigBee receiver of the camera 12B receives the coded information dedicated to the camera and expressly recognized by the receiver of the camera, it generates the switching of a switch, implementing control commands to be executed by the camera, such as filming the station of the cashier, as well as a validation of the receipt of the information resulting in a return transmission (arrow V1) of a response information to the receiver device 4 of the triggering device 21 which can 3038114 16 then stop transmitting the initial information to the camera. At the same time, the security guard P receives on his "pager" the information which is dedicated to him, warning him of a cash incident. It validates the reception of the information via a button 51 on its pager which switches a switch, generating the emission by ZigBee (arrow V2) of a response information dedicated to the receiver device 4 of the trigger device 21 which then ceases. to issue the initial information for the vigil. The security guard physically goes to the scene (arrow V3).

With regard to FIG. 3, the detection device 22 detects the presence for a certain time of a client C in front of the showcase 11. This switches an interface switch between the detector 22 and the processing means, which generates the ZigBee transmission of coded information dedicated to a seller V (arrow Z). The seller 15 is thus notified in real time so as to go as quickly as possible in front of the showcase (so the appropriate place) and at the appropriate time. Receiving the message dedicated to him on the disposiotif receiver 5 (a pager), the seller validates by a button 51 on his pager 5 that he received the information, which in turn sends back (arrow V2) information of 20 response to the device ZigBee receiver 22 which then stops the transmission of the initial signaling information. The seller V then goes to the customer C (arrow V3). Note that as long as the vendor V has not validated the receipt of the information, the ZigBee transmitter of the device 22 continues to transmit the information. It is also possible to implement another procedure: for example, after a lapse of time after which the seller has not validated, the information is sent to another seller identified and recorded in the processing means associated with the device 22.

On the other hand, more and more, especially for high-tech articles, stores are putting the items under lock and key. It is convenient and safe for the shop window to open not with a key but with an automated system in response to an electronic order, and in addition by an authorized person. Thus, in the illustrated example, the window 11 is provided with an opening and closing system 7 which can be remotely actuated via a control device using ZigBee technology, the system 7 thus also being equipped with ZigBee technology. The control device 10 is for example the seller's pad 5 which comprises a transmitter and a ZigBee receiver, a push button 52 (distinct from the message validation push button 51), electronic processing means and a dry contact constituting the interface between the push button 52 and the processing means. The ZigBee receiver of the open / close system 7 is configured to accept only the coded information corresponding to the specific vendor V. In a complementary manner, a ZigBee call terminal (same principle of operation as the terminal call the example of the box of Figure 2) can be arranged near the window 20 so that the customer V can call the seller V who will receive the message on his pager. The invention also relates to a method of monitoring and / or calling by terminal comprising at least one step of triggering a signal, at least one radio frequency data communication step, characterized in that it uses the ZigBee communication protocol to transmit data from the signal processing, and the triggering step is related to the monitoring of a location and / or to and in that it further comprises the following steps : 3038114 18 - processing of the signal detected during the triggering step to generate information to be communicated associated with this signal, - transmission of the information by ZigBee communication, - reception of the information and processing of the information, l information 5 that could be relayed by transmitters / receivers under ZigBee protocol. The information is received and processed to be displayed as a readable text message on a display screen, and possibly to control / actuate automated technical devices, such as cameras, door lock system, display system opening the display windows of the products, starting a lighting, etc ... Thus, the installation and the method of the invention allow, in particular via the use of the ZigBee protocol, to transmit in real time a 15 urgent information to prevent a person as quickly as possible, and this by providing a low-energy installation, low cost of implementation, quick and easy implementation, not requiring a wired connection, and safe to look at radiofrequency information communication.
