Description

Method and device for checking objects on board a vehicle

The present invention relates to methods and devices for controlling one or more objects on board a vehicle. The present invention also relates to the transmission of data stored on an identification tag of at least one package or object on board a vehicle, to a destination device of a communication network infrastructure.

Technology background

The delivery of objects or packages is an activity that requires traceability of these objects or packages throughout their delivery. For this, an identification label is usually affixed to these objects or packages. This identification label contains data relating to the object or package with which it is associated.

Identification tags of the near-field communication type (from the English Radio Frequency Identification, in French identification radiofrequency), called radio-tags, are often used because they allow an operator to read the data stored on these tags. identification by holding a reader close to these tags.

Objects or packages to which RFID tags are affixed can thus be tracked throughout the various stages of delivery. However, the tracking of objects or packages to be transported or delivered is sometimes incomplete in that it is generally limited to informing that the object or package has been taken care of, that it has arrived in a warehouse or that it is being delivered, until it is delivered. For example, when an object or package is not loaded in the vehicle or loaded by mistake in another vehicle, the non-delivery or the delay in delivery due to this oversight or error causes inconvenience for the recipient of the object.

Description of the examples of realization

A method, a system and a device for controlling a set of objects on board a vehicle will now be described in the following with reference in conjunction with FIGS. 1 to 4. The same elements are identified with the same reference signs throughout the following description.

According to a particular and non-limiting embodiment of the present invention, the control of one or more objects on board a vehicle is obtained by the detection of the object or objects on board the vehicle from data representative of each of these objects. Such data are, for example, received by a processor from a device on board the vehicle and configured to read the data stored on a radio tag associated with each object. Each object detected is then associated with the vehicle in which it is loaded. The control of the on-board object or objects is implemented in real time according to the data obtained from each radio tag, such a control comprising for example the verification that the objects to be on-board are, that no unforeseen object being on board is present in the vehicle, that the mass of on-board objects does not exceed a determined threshold, etc.

An object corresponds to any physical object, formed for example by a single device or by a plurality of devices. For this purpose, an object also corresponds to a package containing several objects.

A vehicle corresponds for example to a vehicle with a heat engine, with electric motor(s) or even a hybrid vehicle with a heat engine and one or more electric motors. The vehicle thus corresponds for example to a land vehicle, for example an automobile, a truck, a coach. According to another example, the vehicle corresponds to a flying vehicle, for example an airplane or a drone. According to yet another example, the vehicle corresponds to a vehicle navigating on water, for example a boat, a barge, a container ship. A vehicle according to the invention corresponds to any vehicle suitable for transporting an object from one point to another, whether the vehicle corresponds to a vehicle that is rolling, flying or navigating on water.

Such a process makes it possible to manage or monitor in real time and automatically the loading of one or more vehicles from the data contained in the radio tags associated with the objects loaded in the vehicle, by associating with a determined vehicle a set of objects each associated with a radio tag comprising information on this object. For example, it automatically alerts a control center or a user in the event of a problem loading objects into the vehicle and detects errors quickly and automatically.

schematically illustrates a vehicle 10 intended for transporting a set of objects comprising one or more objects, according to a particular and non-limiting embodiment of the present invention.

According to the example of , the vehicle 10 corresponds to a land vehicle, of the motor vehicle or van type. Of course, vehicle 10 of the is used by way of illustration only and the invention is not limited to this particular type of vehicle. The vehicle 10 corresponds to an autonomous vehicle or not, that is to say a vehicle circulating according to a determined level of autonomy or under the total supervision of the driver.

The vehicle 10 includes a cargo area in which it loads a set of objects, an identification label 13 being affixed to each of the objects of this set.

According to a particular and non-limiting example of embodiment, an identification tag 13 comprises an interface of the RFID type (from the English "Radio Frequency Identification" or in French "Identification par radiofrequency") which allows the reading at short distance of the data stored by this identification tag 13. Such an RFID type identification tag is called an RFID radio tag.

A radio tag 13 corresponds to a marker comprising an electronic chip associated with an antenna. A RFID tag is also known as an RFID tag or RFID transponder. The radio tag 13 advantageously corresponds to a passive RFID tag, that is to say an RFID tag not powered by a battery.

The vehicle 10 advantageously embeds one or more radio-tag readers 12, for example arranged in the trunk or the cargo of the vehicle 10. A radio-tag reader is also called an RFID reader (from the English “RFID-tag” or “RFID transponder”, RFID corresponding to “Radio Frequency Identification”, or in French “Identification par radiofrequency”), interrogators, couplers or base station. Such a reader emits an electromagnetic wave activating a radio tag when the latter enters the coverage radius of the reader. The electromagnetic wave activates an antenna of the radio tag, generating power for this radio tag.

The RFID reader 12 coordinates the RFID communication between the reader and the radio tag 13. The RFID reader also ensures the remote power supply of the radio tag 13. The RFID reader comprises for example a radio frequency module for the transmission and reception signals to and from radio tag 13; a control unit; an antenna and an interface for transmitting the first data received from the radio tag, for example intended for a computer of the on-board system of the vehicle 10.

The communication frequency between the RFID reader 12 and a radio tag 13 is for example equal to 13.56 MHz, the communication range being for example between 10 cm and 1 or 2 m.

The radio tag 13 contains in memory first data representative of an identification of the object on which it is affixed. Thus, when an object comprising a radio tag 13 is deposited or embarked in the vehicle 10, the RFID reader 12 interrogates the radio tag which transmits in return the first identification data of the first object, and this for each object on board the vehicle 10. The data representative of each on-board object and stored in the radio tag 13 associated with each object are for example coded on 96 or 128 bits.

The identification system for objects placed in the safe is not limited to the use of an RFID system but extends to any radio-identification identification system, for example based on Bluetooth®, Wifi® or any other technology.

For example, and according to a variant embodiment, the system for identifying an object placed in the trunk of the vehicle 10 corresponds to a system of the UWB RTLS type (from the English “Ultra-Wideband Real-Time Locating System” or in French "Ultra wideband real-time location system") comprising a radio tag and one or more transmitters using the technique of radio modulation of very short duration pulses over a wide frequency spectrum.

According to another example, the system for identifying an object placed in the trunk of the vehicle 10 corresponds to a WiFi RTLS or Bluetooth RTLS type system, such systems also using a radio tag associated with the object placed in the trunk whose data stored in memory is received by a plurality of readers arranged in the trunk of the vehicle 10.

According to another optional embodiment, the vehicle 10 embeds, in addition to the RFID-type object detection system comprising one or more RFID readers 12, a system for detecting object identification elements with metasurface(s). ) relay. Such a system is for example described in French patent FR 3 103 327 A1 published on May 21, 2021. Such a metasurface detection system advantageously comprises one or more metasurface detection devices. Such a metasurface detection device comprises an identification reader configured to read the data stored on an identification tag affixed to each object (for example the radio tag 13) via at least one antenna and at least one metasurface configured to to reflect (according to a first determined law) waves emitted by the at least one antenna and intended for the radio tag and to reflect (according to a second determined law) waves coming from the radio tag and intended for the at least one antenna .

According to a particular and non-limiting optional embodiment, the vehicle 10 also comprises a device 14 for transmitting the data stored on each identification tag 13. Such a transmission device 14 is connected in communication with a first remote device 11, by example a "cloud" server 110 (or "cloud" in French), and/or with a second remote device 15, for example a mobile communication device of the smart phone type (from the English "smartphone"), tablet or connected object. The data transmission system 14 receives, for example, the data stored on each radio tag 13 from the RFID reader(s) 12 to transmit them to the first remote device 11 and/or the second remote device 15.

According to a particular and non-limiting example of embodiment, the device 14 comprises a long-distance communication interface 143 which makes it possible to establish communication with other devices such as for example the first destination device 11. The long-distance communication interface 143 corresponds for example to a transmitter configured to transmit and receive information and/or data via a communication channel. The long distance communication interface 143 comprises for example a modem and/or a network card and the communication channel can for example be implemented in a wired and/or wireless medium.

Data such as those stored on an identification tag 13 can be transmitted by the device 14 to the first remote device 11 using a cellular-type long-distance communication network such as a 4G (or 5G) network based on the LTE standard (from English Long Term Evolution to French “Evolution à long terme”) defined by the 3GPP consortium.

According to a particular and non-limiting embodiment, the device 14 comprises a block 141, 142 of short distance communication interfaces to communicate with external devices, for example with an identification tag 13 or a device 15. The block 141 , 142 of short distance communication interfaces includes one or more of the following interfaces:

- RF radio frequency interface, for example of the Wi-Fi® type (according to IEEE 802.11), for example in the 2.4 or 5 GHz frequency bands, or of the Bluetooth® type (according to IEEE 802.15.1), in the band frequency at 2.4 GHz, or Sigfox type using UBN (Ultra Narrow Band English) or LoRa radio technology in the 868 MHz frequency band.

- USB interface (from the English "Universal Serial Bus" or "Universal Serial Bus" in French);

- HDMI interface (from the English "High Definition Multimedia Interface", or "High Definition Multimedia Interface" in French);
- RFID interface.

Data such as those stored on an identification tag 13 can be transmitted by the device 14 to the second remote device 15 via one of the short distance communication interfaces of block 142.

According to the particular and non-limiting embodiment of the device 14 illustrated in , the device 14 comprises a short-distance communication interface 141, for example of the RFID type, which is configured to establish a short-distance communication with an identification tag 13 affixed to each package on board the vehicle 10. Such a short-distance communication interface distance 141 corresponds for example to reader 12 and replaces the latter (or complements the latter).

According to the particular and non-limiting embodiment of the device 14 illustrated in , The device 14 also comprises another short distance communication interface 142, for example of the Wi-Fi® or Bluetooth® radiofrequency type which is configured to establish a short distance communication with the second remote device 15.

The second remote device 15 for example hosts an application dedicated to establishing a short-distance communication with the short-distance interface 142. The second remote device 15 is for example also configured to establish a long-distance communication, for example of the type 4G or 5G, with the first remote device 11 of the communication network infrastructure 110.

If a short distance communication is established or can be established between the device 14 and the device 15 via the short distance interface 142 then a communication channel C ₁₁ is established between the device 14 and the device 15.

If a long distance communication is established or can be established between the device 15 and a piece of equipment of the communication network infrastructure 110 then a communication channel C ₁₂ is considered to have been established between the device 15 and the destination device 11 of the communication network infrastructure 110. If the communication channels C ₁₁ and C ₁₂ are established then the device 14 can communicate with the first remote device 11 of the communication network infrastructure 110 via a communication channel C ₁ formed of communication channels C ₁₁ and C ₁₂ .

If a long distance communication is established or can be established between the device 14 and a piece of equipment of the communication network infrastructure 110 via the long distance communication interface 143, then a communication channel C ₂ is considered to be established between the device 14 and the first remote device 11 of the communication network infrastructure 110.

A process for controlling a set of objects on board the vehicle 10 is advantageously implemented by the vehicle 10 (that is to say by one or more devices on board the vehicle 10, for example one or more computers ). According to another exemplary implementation, the process is implemented by a system comprising the computer or computers in combination with a plurality of RFID readers 12, 141. According to a variant of this other exemplary implementation, the system comprises in in addition to a metasurface(s) object detection system.

In a first operation, each object on board the vehicle 10 is detected. The detection is obtained from the data read on the radio tag 13 associated with or affixed to each object by the reader 12, 141. The reading of the data contained on the radio tag by the reader 12, 141 is advantageously carried out automatically when the radio tag passes close to the reader 12, 141, that is to say in the field of action of the reader 12, 141 corresponding to its radiation range which depends on the wavelength used.

The data stored on a radio tag 13 advantageously corresponds to identification data of the object with which the radio tag 13 is associated.

According to a variant, the data also includes a set of additional information on the object with which the radio tag is associated. For example, the data stored on a radio tag includes one or more of the following data, in any possible combination:

- data representative of the type of object; and or

- data representative of the dimensions of the object; and or

- data representative of the mass or weight of the object; and or

- data representative of a composition of the object, for example all the particular elements forming the object, or when the object corresponds to a package comprising several objects, the list of objects included in the package; and or

- data representative of the construction material(s) of the object; and or

- data representative of the recipient of the object, for example the address and/or the name of the recipient; and or

- data representative of the vehicle intended to transport the object; and or

- data representative of an expected delivery date of the object; and or

- data representative of a level of fragility of the object; and or

- data representative of a level of danger of the object, for example flammable object, dangerous material, explosive material, etc. ; and or

- data representing a value of the object.

The list above is given by way of illustrative example and is not exhaustive, any data representing a characteristic of the object that can be stored in the radio tag associated with the object.

The detection of objects, that is to say the reading of the data stored on the radio tags 13 by the reader or readers 12, 141 is implemented each time an object is loaded into the vehicle 10. According to another example, the detection of objects, that is to say the reading of the data stored on the radio tags 13 by the reader or readers 12, 141 is implemented when all the objects have been embarked, for example upon detection the closing of the safe door, following a user action such as a click on a button of an HMI (human machine interface) of a mobile application of a mobile communication device such as the second remote device 15 in communication with the RFID system of the vehicle 10 comprising the reader(s) 12, 141.

In a second operation, all of the objects detected as being on board the vehicle 10 in the first operation are associated with the vehicle 10.

Once the objects have been detected, the data representative of each object are for example stored in the memory of a computer of the vehicle 10, for example a computer connected in communication with each RFID reader 12, 141.

The association between a detected object and the vehicle 10 is for example recorded in the memory in a correspondence table, called LUT (from the English “Look-Up Table”) by matching an identifier of the vehicle with an identifier of each object, the identifier of each object then being associated with each set of data representative of this object.

According to a variant, the association between the objects detected and the vehicle 10 is recorded in the memory of the first remote device 11 and/or of the second remote device 15. According to this variant, the data representative of each object detected by the RFID system of the vehicle 10 are transmitted by the vehicle 10 (for example by the device 14) to the first remote device 11 and/or the second remote device 15.

The association is for example carried out as objects are detected. According to a variant, the association is implemented following a particular event, for example the closing of the doors of the trunk of the vehicle 10, a user action such as a click on a button of an MMI (human machine interface) d a mobile application of a mobile communication device such as the second remote device 15, upon receipt of a user request sent for example from the first remote device 11.

In a third operation, the set of objects associated with the vehicle 10 is checked according to the data obtained from the radio tag 13 associated with each object of the set of detected objects. The control is for example implemented by the device having received the data representative of the detected objects and/or the device storing the association information between the objects and the vehicle 10, for example a computer of the vehicle 10, the first remote device 11 and/or the second remote device 15.

The check(s) implemented depend, for example, on the nature of the data received and/or the type of vehicle 10. The check corresponds, for example, to a set of checks by comparing data representative of the objects on board the vehicle 10 with data reference and/or threshold values.

To this end, the control includes, for example, a set of comparisons comprising one or more comparison operations, the result of this or these comparisons implemented making it possible to determine an action to be taken.

For example, the comparison(s) implemented correspond to one or more of the following comparisons, in any possible combination:

- a comparison of the set of objects detected with a reference list of objects intended to be transported in the vehicle 10;

- a comparison of the type or types of objects on board with a list of objects authorized to be transported in the vehicle 10;

- a comparison of a total mass of the set of detected objects with a maximum authorized mass associated with the vehicle 10;

- a comparison of a volume of the set of detected objects with a maximum loading volume of the vehicle 10;

- a comparison of a set of recipient addresses of the set of detected objects with a set of delivery addresses associated with the vehicle 10; And

- a comparison of a number of objects of the same type with a reference number associated with the type.

Depending on the result of the comparison or comparisons implemented, one or more alerts are for example issued to alert a controller or a user of an error or a problem on the loading of the vehicle 10. Such an alert is for example displayed on the screen of the second remote device 15 to alert the person possessing or using this second remote device 15. According to a variant, a sound alert is for example emitted by an audio rendering device on board the vehicle 10 or arranged in the zone of loading, such an audio rendering device being controlled by a device in communication with the device in charge of the process.

For example, objects identified as being shipped are compared to a predefined list of objects expected to be shipped. If a difference appears, an alert is issued indicating which objects are missing or which objects have been loaded by mistake.

According to another example, if the total mass of the objects detected as being on board exceeds a threshold value, for example the authorized total laden weight of the vehicle 10, then an alert is issued.

According to yet another example, if the nature of at least some of the objects on board is not compatible with the nature of the vehicle (for example chemicals or explosives in a vehicle not intended for this purpose or refrigerated products in a vehicle 10 not thermally insulated without an adequate air conditioning system), then an alert is issued.

According to another example, if one or more addresses of recipients of objects are not part of the list of delivery addresses provided for the vehicle 10, then an alert is issued.

The control is for example implemented automatically, for example when the doors of the vehicle 10 are closed or on action by a user, for example when a user requests it via an MMI provided for this purpose.

The data retrieved from the radio tags 13 and stored in the memory of a computer or a remote device are for example accessible via a web interface or a mobile application executed on a mobile communication device such as the second remote device 15.

Dynamic and automatic management of the objects on board a specific vehicle such as the vehicle 10 is thus enabled thanks to the automatic identification system (RFID system, optionally coupled to the metasurface detection system) on board the vehicle 10.

Such dynamic management of objects consists in monitoring or monitoring different aspects of each object in real time (for example weight, volume, quantity of units per object, etc.), which allows in particular:

- trigger real-time alerts (forgetting to load and/or unload, theft, inversion between vehicles, weight overload, non-compliant product present in the vehicle, dangerous product indication, loading or unloading instructions linked to an object, limitation the quantity by type of object, state of the object, etc.); and or

- to manage the contents of each vehicle of a fleet of delivery vehicles (for example a set of vans or a set of drones), by authorizing only certain objects, in a given quantity, and by carrying out an inventory in time real or masked time of each vehicle, with the possibility of organization between each vehicle; and or

- to establish statistics on the content (weight, value, size, etc.) on board the vehicle, on loading and unloading (duration, place, etc.), on its use (tool not used, product never used, essential tool, etc.), on the carbon footprint of each object by calculating the travel time of the object associated with the type of vehicle.

According to a particular embodiment, the vehicle 10 carries a satellite geolocation system configured to determine the current position of the vehicle 10, the vehicle 10 carrying for this purpose a receiver of a GPS or Galileo type system for example in communication with a computer of the on-board system of the vehicle 10. The positions of the vehicle 10 (for example during the delivery journeys made) are transmitted to the first remote device 11 and/or to the second remote device 15 for real-time monitoring of the delivery of the objects on board and associated with the vehicle 10, for example by the recipients of the objects or by a controller of the company ensuring the deliveries and managing the fleet of delivery vehicles.

schematically illustrates a set or a fleet of vehicles adapted for the delivery of objects, according to a particular and non-limiting embodiment of the present invention.

The vehicles 21 to 24 of the set 2 of vehicles each correspond for example to the vehicle 10 or to a drone for example.

The number of vehicles 21 to 24 is not limited to 4 but extends to any number, for example 10, 100, 1000 or more vehicles.

The vehicles 21 to 24 are advantageously configured to communicate with each other via wireless connections, each vehicle 21 to 24 being further configured to communicate with a remote device 11, such as a central “cloud” server. Each vehicle 21 to 24 transmits, for example, to the other vehicles the list of objects associated with and on board this vehicle, these objects each being identified by a radio tag, namely the radio tags 210 for the vehicle 21, the radio tags 220 for vehicle 22, RFID tags 230 for vehicle 23 and RFID tags 240 for vehicle 24.

The remote device 11 receives for example from each vehicle 21 to 24 the list of objects on board each vehicle, the remote device 11 storing in LUTs the associations between the objects being delivered and the vehicles transporting these objects. When a delivery is made by a vehicle, a reading of the radio tag associated with the object delivered triggers, for example, the transmission of information representative of the delivery made automatically to the remote device 11 which updates the LUT associated with the vehicle having made the delivery. This makes it possible to know in real time the status of deliveries, the volume available in the vehicle, the total loaded weight of the vehicle, etc.

The remote device 11 also receives, for example, the positions of each vehicle in real time for better tracking of deliveries, which makes it possible, for example, to alert a recipient of an object of the estimated delivery time, of a possible delay, etc.

If a vehicle encounters another problem, the remote device 11 requires, for example, that another vehicle of the set join the broken down vehicle to recover its load. This is made possible by the real-time monitoring of objects on board, objects delivered, the position of each vehicle and the volume available in each vehicle 21 to 24 at any time.

Such a system allows real-time monitoring of the delivery of objects and of the vehicles providing the deliveries.

schematically illustrates a device 3 configured to control a set of objects on board a vehicle, for example the vehicle 10, according to a particular and non-limiting embodiment of the present invention. The device 3 corresponds for example to a device on board the vehicle 10, for example a computer. According to other examples, the device 3 corresponds to the first remote device 11, to the second remote device 15, to the communication device 14 or to a combination of several of these devices

The device 3 is for example configured for the implementation of the operations described with regard to FIGS. 1 and 2 and/or of the steps of the method described with regard to the . Examples of such a device 3 include, but are not limited to, on-board electronic equipment such as a vehicle's on-board computer, an electronic computer such as an ECU ("Electronic Control Unit"), a telephone smartphone, a tablet, a laptop, a server, a connected object, an RFID reader. The elements of device 3, individually or in combination, can be integrated in a single integrated circuit, in several integrated circuits, and/or in discrete components. The device 3 can be made in the form of electronic circuits or software (or computer) modules or else a combination of electronic circuits and software modules.
