Detailed ways

In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

The network architecture and business scenarios described in the embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute limitations on the technical solutions provided by the embodiments of the present application. The evolution of the technology and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

Please refer to FIG. 1 , which shows a schematic diagram of a network architecture of the Internet of Things provided by an embodiment of the present application. The network architecture of the Internet of Things may include: a vehicle-mounted device 110, a terminal device 120, and a network-side device 130;

The vehicle-mounted device 110 may be an IoT device installed on a vehicle in the Internet of Things.

For example, the vehicle-mounted device 110 may be a vehicle-machine device in a vehicle.

Alternatively, the vehicle-mounted device 110 can also be an IoT device installed outside the vehicle-machine device in the vehicle, and the vehicle-mounted device 110 can be connected to the vehicle-machine device and can communicate with the vehicle-machine device to trigger the vehicle-machine device to execute Some specific operations, for example, can trigger the on-board equipment to control the vehicle to whistle or flash the lights.

The terminal device 120 may be a mobile electronic device on the user side. For example, the terminal device 120 may be a smart phone, a tablet computer, a smart watch, a smart TV, and so on.

In another possible implementation manner, the terminal device 120 may also be a client entity (which may be a virtual entity) running on the basis of the user's mobile electronic device, for example, the terminal device 120 may be running in a smart phone for The in-vehicle device 110 is an APP for managing configurations.

The network side device 130 may be a server deployed on the network side. For example, the server may be a single server, or the server may also be a server cluster composed of multiple servers. The network-side device 130 may be a computer device that provides cloud support for remote control of vehicle-mounted devices.

In parking lots, especially in buildings, it is usually not possible to support satellite-based positioning technology. Therefore, in a feasible solution involved in this application, when searching and locating a car reversely in the parking lot, wireless communication technologies such as Bluetooth, Ultra Wide Band (UWB), Wi-Fi, etc. can be used to pass through the parking lot. The preset network element nodes are used to locate the mobile phone.

For example, the following Bluetooth positioning solution in a parking lot is mainly realized by arranging Bluetooth beacons (Beacon) in the parking lot. Wherein, the coordinates of the Bluetooth beacon are used as the geographic coordinates of the car-finding navigation system. The management personnel will make a reasonable layout of Beacon according to the environment of the indoor parking lot in advance. The user's mobile phone APP (Application, application program) combines the parking lot map, calculates the current position of the mobile phone through the coordinates broadcast by multiple beacons, and navigates accordingly.

As a beacon, a Bluetooth beacon has the function of broadcasting location information. The mobile phone is receiving the broadcast information of multiple Bluetooth beacons and parsing the location information. Based on the obtained location information, the mobile APP calculates the location of the mobile phone in the parking lot through a positioning algorithm.

The Bluetooth beacon can choose a built-in disposable battery as a power supply. Optionally, the Bluetooth beacon can monitor its own voltage and report it to the mobile phone APP.

The positioning accuracy of positioning through Bluetooth beacons is usually 3-5 meters, and the positioning delay is usually within 2s, and it can support single-floor positioning, multi-floor positioning automatic switching, regional positioning and other functions.

The solution for positioning through Bluetooth beacons can also support single-layer/multi-layer shortest path search, real-time navigation, static navigation, etc.

Taking the above-mentioned beacon as a Bluetooth beacon as an example, the above-mentioned car finding scheme can be as follows:

The development and management personnel of the APP with the car-finding function make a map of the parking lot in advance, and set up multiple Bluetooth beacons in the parking lot.

When the user finishes parking in the parking lot, he can click the parking control on the mobile APP. At this time, the mobile APP calculates the coordinates of the mobile phone through the received coordinates broadcast by multiple Bluetooth beacons, and uses the coordinates of the mobile phone as the vehicle coordinates. Coordinates are saved.

When the user is looking for a car in the parking lot, he can click the car-finding control on the mobile APP. At this time, the mobile APP calculates the coordinates of the mobile phone through the coordinates broadcast by multiple Bluetooth beacons received, and uses the coordinates of the mobile phone as the user's The current location of the vehicle, using the coordinates of the previously recorded vehicle as the target location, navigates in the map of the parking lot.

However, the above solution needs to pre-deploy network element facilities in the parking lot, and needs to make a corresponding parking lot map, which requires a specific parking lot to be realized, resulting in a small application range for car search in the parking lot; on the other hand At present, the management of the parking lot is scattered, and it is difficult to implement a unified positioning logic on the mobile phone. As a result, users need to use different applications in different parking lots, which seriously affects the efficiency of car search in the parking lot. However, if the vehicle is triggered to send a reminder by sending out a Bluetooth signal directly through a terminal device such as a remote control key, the range of the car search will be small because the propagation distance of the Bluetooth signal is too short, which will also affect the efficiency of car search in the parking lot.

The schemes shown in the subsequent embodiments of the present application provide a new car-finding scheme. Through the transmission of target user identification information between the on-board equipment of the vehicle itself, the rapid reminder of the vehicle location can be realized, thereby expanding the scope of car-finding. Range, improve the efficiency of car search.

Based on the above embodiments shown in FIGS. 2 to 4 , please refer to FIG. 5 , which shows a schematic framework diagram of a car-finding system provided by an embodiment of the present application. As shown in FIG. 5 , the car-finding system includes a target vehicle 51 , an intermediate vehicle 52 , an intermediate vehicle 53 , and a terminal device 54 ; wherein, the target vehicle 51 , target vehicle 52 , and target vehicle 53 are respectively equipped with on-board devices. The terminal device 54 is a terminal corresponding to the target vehicle 51 ; wherein, each vehicle-mounted device has its own identification information, and the terminal device 54 also stores the identification information of the vehicle-mounted devices installed in the target vehicle 51 .

In the above-mentioned system framework shown in FIG. 5 , the process for the user to find the target vehicle 51 through the terminal device 54 is as follows:

When looking for a car, the vehicle-mounted device 1 installed on the target vehicle 51 first sends out a broadcast message 1 containing target user identification information. The sending address of the broadcast message 1 is the address of the vehicle-mounted device 1 (referred to as address 1 for short). The above target user identification information is matched with the vehicle-mounted device 1 , for example, the target user identification information and the user identification information of the vehicle-mounted device 1 are the same identification information.

After receiving the broadcast message 1, the vehicle-mounted device 2 installed on the intermediate vehicle 52 saves the address 1 locally, and sends a broadcast message 2 including target user identification information. The sending address of the broadcast message 2 is the address of the vehicle-mounted device 2 (referred to as address 2 for short).

After receiving the broadcast message 2, the vehicle-mounted device 3 installed on the intermediate vehicle 53 saves the address 2 locally, and sends the broadcast message 3 containing the target user identification information. The sending address of the broadcast message 3 is the address of the vehicle-mounted device 3 (referred to as address 3 for short).

After the terminal device 54 receives the broadcast message 3, it compares the target user identification information carried therein with the user identification information of the vehicle-mounted device (i.e., the above-mentioned vehicle-mounted device 1) on the vehicle it wants to find, and finds that the two match, then A response message 1 including the target user identification information is sent to address 3 (wherein, the response message corresponds to the above-mentioned first message or second message).

The vehicle-mounted device 2 installed on the intermediate vehicle 52 receives the response message 2 and determines that the corresponding address 1 is locally stored, and sends a response message 3 containing the target user identification information to the address 1 .

The vehicle-mounted device 1 installed on the target vehicle 51 receives the response message 3, determines that the target user identification information contained therein matches its own user identification information, and then sends out a reminder, such as sounding a whistle, to remind the user.

In another possible solution, based on the above-mentioned embodiments shown in Figures 2 to 4, in the car-finding scenario, the target vehicle may not actively send a broadcast message, but broadcast from the terminal device, including the target user The message of the identification information triggers the target vehicle to issue a reminder. For example, still taking the target vehicle 51, intermediate vehicle 52, intermediate vehicle 53, and terminal device 54 involved in Fig. 5 as an example, the process of finding a car is as follows:

When looking for a car, the user triggers the terminal device 54 to send a message 1 containing target user identification information.

The vehicle-mounted device 3 installed on the intermediate vehicle 53 receives the message 1, determines that the target user identification information contained therein does not match its own user identification information, and sends a message 2 containing the target user identification information;

The vehicle-mounted device 2 installed on the intermediate vehicle 52 receives the message 2, determines that the target user identification information contained therein does not match its own user identification information, and then sends a message 3 containing the target user identification information;

The on-vehicle device 1 installed on the target vehicle 51 receives the message 3, determines that the target user identification information contained therein matches its own user identification information, and sends out a reminder. Wherein, the above message 1, message 2 and message 3 may be sent by broadcasting.

In the embodiment of the present application, in the case that the target user identification information does not match the first vehicle-mounted device, the first vehicle-mounted device may also perform a reminder operation, so as to strengthen the reminder of the vehicle location.

At this time, in the above-mentioned step 510, the first vehicle-mounted device may add the target user identification information carried in the trigger instruction to the first sent in a broadcast message.

In this embodiment of the present application, the above trigger instruction may also be an instruction issued by an upper-layer application of the first vehicle-mounted device. For example, before getting off the vehicle, the user can set the car-finding time in the upper-layer application of the first vehicle-mounted device, and when the car-finding time arrives, the upper-layer application of the first vehicle-mounted device can issue the trigger instruction.

2) The current moment reaches the target moment.

In the embodiment of the present application, when the target time is reached, the first vehicle-mounted device may send the above-mentioned first broadcast message.

For example, if the target time is preset as 7:00 p.m. in the first vehicle-mounted device, then when the system time reaches 7:00 p.m., the first vehicle-mounted device can send the above-mentioned first broadcast message.

Wherein, the above-mentioned target time may be a time set by the user, or the above-mentioned target time may also be a time calculated or predicted according to the user's historical travel time.

Wherein, the above-mentioned target area may be an area set by the user, for example, the target area may be a parking lot area preset by the user; or, the above-mentioned target area may also be an area obtained by statistics or prediction based on the user's historical travel positions.

The above four trigger conditions can be used alone or in combination. For example, when the current moment is within the target time interval and the first vehicle-mounted device is within the target area, the first vehicle-mounted device may send the above-mentioned first broadcast message.

Step 602, the first vehicle-mounted device receives a first broadcast message sent by the second vehicle-mounted device, and the first broadcast message includes target user identification information and a first address of the second vehicle-mounted device.

In this embodiment of the present application, the second vehicle-mounted device may be the above-mentioned target vehicle-mounted device, or may be other vehicle-mounted devices other than the target vehicle-mounted device.

Step 603, the first vehicle-mounted device records the corresponding relationship between the target user identification information and the first address in the first routing table.

Step 604, the first vehicle-mounted device sends a second broadcast message, where the second broadcast message includes target user identification information and a second address of the first vehicle-mounted device.

Step 605, the terminal device receives a fourth broadcast message sent by the fifth vehicle-mounted device, where the fourth broadcast message includes target user identification information and an address of the fifth vehicle-mounted device.

Wherein, the above-mentioned fifth vehicle-mounted device may be the above-mentioned first vehicle-mounted device, or, the above-mentioned fifth vehicle-mounted device may be the above-mentioned target vehicle-mounted device, or, the above-mentioned fifth vehicle-mounted device may be other than the above-mentioned first vehicle-mounted device and the target vehicle-mounted device other vehicle equipment.

Wherein, the foregoing fourth message may be a response message of the terminal device to the foregoing fourth broadcast message.

Wherein, the fourth message is used to instruct the fifth vehicle-mounted device to send a fifth message to the sixth vehicle-mounted device when the target user identification information does not match the fifth vehicle-mounted device, and the fifth message includes the target user identification information.

In a possible implementation manner, the fourth message is further used to instruct the fifth vehicle-mounted device to perform the second reminder operation when the target user identification information matches the fifth vehicle-mounted device. At this time, the above-mentioned fifth vehicle-mounted device is the target vehicle-mounted device.

In a possible implementation manner, the broadcast message includes operation identification information, and the operation identification information is used to indicate at least one of the first reminding operation and the second reminding operation.

In a possible implementation manner, the fourth message includes operation identification information, and the operation identification information is used to indicate at least one of the first reminding operation and the second reminding operation.

In a possible implementation manner, when the target user identification information does not match the terminal device, the broadcast message is discarded.

In a possible implementation manner, after receiving the fourth broadcast message sent by the fifth vehicle-mounted device, the terminal device receives the broadcast message containing the target user identification information again, and may discard the broadcast message received again.

Since the above-mentioned broadcast message containing the target user identification information is sent by broadcasting, the terminal device may receive broadcast messages containing the target user identification information respectively sent by multiple different vehicle-mounted devices, that is, from There may be multiple transmission paths of broadcast messages between the target vehicle-mounted device and the terminal device; if the terminal device responds to each broadcast message containing the target user identification information, it may result in a transmission path between the target vehicle-mounted device and the terminal device. All the on-vehicle devices on the delivery path of multiple broadcast messages may perform reminder operations, which may cause interference to the user's accurate positioning of the target vehicle. Therefore, in the embodiment of the present application, the vehicle-mounted device may respond to the sender of the first received broadcast message containing the target user identification information as the fifth vehicle-mounted device, and for the subsequent received broadcast message containing the target user identification information broadcast messages are not responded to.

The incoming response message (that is, the above-mentioned first message).

In another possible implementation manner, the foregoing first message may also be a message directly sent by the terminal device.

Step 608, the first vehicle-mounted device sends a second message to the second vehicle-mounted device corresponding to the first address according to the first routing table.

Wherein, in the case that the target user identification information does not match the first vehicle-mounted device, the first vehicle-mounted device sends a second message to the second vehicle-mounted device, and the second message includes the target user identification information.

In this embodiment of the present application, the first vehicle-mounted device may query the first routing table of the first vehicle-mounted device according to the target user identification information to obtain the first address; and send the second message to the second vehicle-mounted device according to the first address.

For example, when the identification information of the target user does not match the identification information of the first vehicle-mounted device, and the first address corresponding to the target user identification information is stored in the first vehicle-mounted device, the first vehicle-mounted device sends the first address corresponding to the first address to the first vehicle-mounted device. The second vehicle device sends the second message.

In this embodiment of the present application, when the first vehicle-mounted device receives the first message, if it is determined that the target user identification information contained therein does not match its own user identification information, and the previously received message containing the target The sending address of the broadcast message of the user identification information sends a response message containing the target user identification information to the sending address, so as to transmit the response message containing the target user identification information to the target vehicle-mounted device.

In another possible implementation manner, before sending the second message to the second vehicle-mounted device corresponding to the first address, the method further includes:

The first vehicle-mounted device queries the first routing table of the first vehicle-mounted device according to the target user identification information;

In the embodiment of the present application, the method for the first vehicle-mounted device to determine whether the target user identification information matches the user identification information of the first vehicle-mounted device is the same as the method for the target vehicle-mounted device to determine whether the target user identification information matches the user identification information of the first vehicle-mounted device The method is similar, that is, one of the following two methods:

1) The first in-vehicle device compares the target user identification information with its own user identification information, or compares the target user identification information with the information generated by its own user identification information to be matched; if the two are inconsistent, then determining that the target user identification information does not match the user identification information of the first vehicle-mounted device;

2) The first in-vehicle device obtains the routing table item according to the target user identification information query, and judges whether the address in the routing table item is a designated address, if it is not a designated address, then determines that the target user identification information does not match the user identification information of the first in-vehicle device .
