    State of the art
    Some equipment, such as electrical equipment, is sold through distribution channels that do not allow their manufacturer to know where they are going to be installed and therefore what is their final destination. But the knowledge of the final destination of a device is crucial for a manufacturer: μί wants to monitor the evolution of its equipment and offer services, such as maintenance, associated with this equipment and make reminders of earc.

The invention also relates to the device used to help the geolocation of a device, said device comprising: a microcontroller comprising at least one microprocessor for performing the data processing and a memory for storing data, a detection circuit and for receiving signals transmitted by terminals placed in its environment, arranged to collect network data comprising the identifiers of the communication network terminals, called first communication networks, placed in the environment of the device and the power in reception of the transmitted signals by each terminal, - a motion detector, connected to an input of the microcontroller and arranged to detect whether the device is in motion or in a fixed position, - a clock managed by the microprocessor, - a detection circuit for the presence of a terminal of a communication network, said second communication network, and transmission to transmit said network data collected on this network according to a communication protocol.
    According to a particularity, the terminals of the first communication networks from which the network data are collected are WIFI access points to bluetooth.
    In another feature, said second communication network is ype LPWAN ("Low Power Wide Area Network").
    BRIEF DESCRIPTION OF THE FIGURES Other features and advantages will appear in the following detailed description with reference to the accompanying drawings, in which: FIG. 1 illustrates the operating principle of the invention.
    DETAILED DESCRIPTION OF AT LEAST ONE EMBODIMENT The invention consists in determining the final destination of a piece of equipment E, such as for example an electrical equipment which will often be intended to be installed in a closed interior space.
    This invention is implemented by means of a device 1 attached to equipment E whose final destination is to be known. Preferably, the device 1 is fixed directly on the equipment E, on a support on which is placed 'equipment or on an envelope in which the equipment is packed.
    In the following description, there are first Dommunication networks having one or more terminals, designated B1 to Bn, placed in the environment of the device 1 and for determining the geographical position of the device and a second communication network comprising one or several Dornes, designated L, within range of the device and used to transmit data to a remote CPU unit, responsible for determining the location of the device.
    Referring to Figure 1, the device 1 comprises a housing in which is positioned: - a microcontroller 13 comprising at least one microprocessor for performing data processing and a memory for storing data, - a circuit 10 for detection and reception signals transmitted by the terminals B1-Bn of the first communication networks, placed in its environment. It will be for example terminals or points of access WIFI, Bluetooth or any other type of beacon ("beacon" in English) or mixture of these technologies, a motion detector 12, for example accelerometer type, connected on a input of the microcontroller 13 and arranged to detect whether the device is moving or in a fixed position, - a clock, for example of the software type present in the microcontroller 13 and managed by the microprocessor, - a circuit 11 for detecting the presence of a terminal L of a second communication and data transmission network on this network according to its communication protocol. This second communication network is for example long-distance and low-speed type LPWAN (for "Low Power Wide Area Network") and is based on a protocol such as LoRaWAN ("for Long Range Wide Area Network") or the one developed by Sigfox.
    According to the invention, using these various components, the device 1 functions as follows:
    When the microcontroller 13 detects that the device is in a fixed position, that is to say that it no longer receives a signal from the motion detector 12, and that it has not moved for a predetermined period of time (for example set at 15 minutes) measured by its clock, it starts the detection circuit 10 to collect the following network data: - the identifier (B1_ld to Bnjd) of each terminal B1-Bn of the first communication networks, present in its environment (commonly called BSSID which corresponds to the MAC address of the WIFI access point), the reception power (B1_RSSI-Bn_RSSI) signals emitted by each terminal B1-Bn at its destination. In known manner, the measurement of the power in reception, called RSSI (for "Received Signal Strength Indication") can notably be used within a WIFI network to geolocate a device inside.
    Once these data have been collected for this position, the microcontroller 13 stores them in its memory.
    Via the detection and transmission circuit 11, the microcontroller 13 carries out a verification of the presence of a terminal L of a second communication network as described above, on which the collected network data can be issued: - If such a terminal L is within range, the microcontroller 13 controls the detection and transmission circuit 11 for the transmission of data on this network, - If such a terminal L is not within its reach, the microcontroller 13 stores the data in memory and will attempt a new transmission later, when a communication network of the type of the second communication network will be available. The microcontroller 13 implements these steps as long as it regularly receives a motion signal from the motion detector 12. After each fixed position, the microcontroller 13 therefore waits a determined duration before collecting the network data and sending them through the communication network. The waiting time after a fixed position may be always the same or adapted according to different criteria, for example related to the frequency of movement of the device from one position to another.
    Thus, thanks to this procedure, it is possible to determine the final position of the equipment E, even if it is positioned in a closed interior space. For this purpose, the processing unit UC determines the geographical position of the device by searching the regularly received data from the device in one or more databases listing the terminals B1-Bn installed and their position. As a function of the attenuation of the signals with respect to each of the terminals B1-Bn, the processing unit is able to determine a position of the device 1, and therefore of the equipment E.
    According to the invention, when the microcontroller 13 has received no motion signal from the motion detector 12 for a determined duration, greater than the duration described above and for example equal to 24 hours, it launches its detection circuit 10 and to collect the network data defined above. The microcontroller 13 then starts the circuit 11 in order to know if a terminal L of a communication network, of the type of the second communication network, is in range of the device 1. If such a network is available, the microcontroller 13 controls the circuit 11 for the transmission of the last network data collected. If such a network is not available, the microcontroller 13 stores the data in its memory, waiting for the detection of such a network. This procedure is implemented by the microcontroller 13 periodically in order to detect any new terminal B1-Bn for determining the geographical position of the device or to specify it and / or any new terminal L allowing the sending of network data to the user. remote CPU unit.
    The solution of the invention thus has many advantages that current solutions can not obtain. It makes it possible to determine the geographical position of a piece of equipment, even if it is located in a closed interior space. In addition, it is optimized to limit the power consumption of the device and thus ensure, in all cases, the determination of the final position of the equipment.
