[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] The present invention provides a solution for finding the coordinates of a terminal device based on near-field communication by combining the existing network deployment strategy, high-precision positioning ability, and data perception characteristics of V2X. In this solution, data interaction between the roadside device and the mobile device is carried out by means of near-field communication, so as to make full use of the convenience of Internet of Things communication and assist in finding the real-time coordinates of a mobile device disconnected from the Internet.

[0042] Specifically, the present application discloses a method for finding the coordinates of a terminal device. This method is applied to roadside devices. Refer to Figure 1 , the method includes:

[0043] Step S101: Obtain device search information, where the device search information at least includes the device identifier of the target device to be searched.

[0044] In this embodiment, when the target system needs to search for a certain target device, it can first pre-determine the predicted area where the target device is located, and then send the device search information to the roadside device in the predicted area. The device search information at least includes the device identifier of the target device to be searched. The device identifier is the unique identifier of the target device to be searched. The target system can be a security system or other systems that can interact with the roadside device. The device search information can be understood as a query instruction for searching for the target device.

[0045] When the target system conducts data interaction with the roadside device, it can use the Internet for long-distance interaction.

[0046] Step S102: Broadcast the device search information.

[0047] The device search information obtained by the roadside device can be directly sent by the target system to the roadside device, or can be broadcast to the current roadside device by other roadside devices or mobile devices. When other roadside devices broadcast the device search information to the current roadside device, it can be achieved through the Internet. Since in order to enable the normal execution of this solution when the mobile device cannot be connected to the network, when the mobile device broadcasts the device search information to the current roadside device, it can be achieved through the near-field communication method.

[0048] Step S103: When obtaining the response information, send the response information to the target system.

[0049] In this step, when the mobile device obtains the response information, it analyzes the device search information and conducts self-check to determine whether it itself is the search object of the device search information. When it itself is the search object, it generates a response result and sends the response result to the roadside device through the near-field communication method. At this time, the roadside device can refer to any roadside device that can conduct near-field communication with the mobile device. The response result at least includes the address information of the mobile device and the device identifier of the mobile device.

[0050] In this embodiment, when the roadside device obtains the response information, it may also feedback to the mobile device a confirmation instruction for indicating that the response information has been obtained. At this time, the roadside device will stop broadcasting the response information only when it obtains this confirmation instruction. If the roadside device does not obtain this confirmation instruction, it is defaulted that there is no roadside device capable of performing near-field communication with the mobile device at the current position, and it is necessary to continue broadcasting the response information until the confirmation instruction is obtained.

[0051] As can be seen from the above solution, in this solution, when a target device needs to be located, the device search information including the device identifier of the target device is sent to the roadside device. When the roadside device obtains the device search information, it broadcasts the device search information to the mobile device by means of near-field communication. When the response information including the address information of the mobile device, which is feedback by the mobile device by means of near-field communication, is obtained, the response information is sent to the sending target system. Since near-field communication can be completed without a network, this solution can assist in locating the real-time coordinates of a device that is disconnected from the Internet when the mobile device is not connected to the network.

[0052] In the technical solution disclosed in this embodiment, in addition to being able to perform near-field communication with a mobile device within its communication range, the roadside device can also send the device search information to other roadside devices through the Internet, so that other roadside devices can jointly assist in finding the target device. Therefore, when the roadside device broadcasts the device search information, in addition to the method of broadcasting the device search information by means of near-field communication, it also includes: broadcasting the device search information to other roadside devices through the Internet. The reason for using the Internet is that the distance between roadside devices is usually relatively long, and data interaction cannot be carried out by using the near-field communication method. Therefore, it is necessary to use the Internet to realize data interaction between roadside devices. At this time, in this embodiment, the source of the device search information obtained by the roadside device can be two, one is the target system, and the other is other roadside devices. In this embodiment, by jointly broadcasting the device search information by multiple roadside devices, the position of the target device can be found and confirmed more quickly.

[0053] Furthermore, in the technical solution disclosed in this embodiment, in addition to obtaining the device search information through the target system and other roadside devices, the device search information can also be obtained by the mobile device. At this time, the device search information is the device search information broadcast by the mobile device by means of near-field communication. At this time, the broadcast range of the device search information can be expanded by means of broadcasting the device search information by the mobile device, thereby increasing the probability of finding the target device.

[0054] In this embodiment, when the mobile device generates the response information, it may not be able to locate itself. Therefore, the address information of the mobile device in the response information generated by the mobile device may be empty. At this time, in order for the target system to determine the location of the mobile device, in this embodiment, when the roadside device obtains the response information, it can also obtain the device identifier of the roadside device (the target system can determine the address information of the roadside device through the device identifier) or the address information, and send the device identifier of the roadside device or the address information of the roadside device together with the response information to the target system, so that the target system can reliably determine the location of the target device.

[0055] In the technical solution disclosed in this embodiment, in order to prevent the roadside device from broadcasting the device search information without limit, in this embodiment, the number of broadcasts of the device search information is limited. Specifically, when broadcasting the device search information, the specific process includes: parsing the device search information to obtain the number of broadcasts of the device search information; determining whether the number of broadcasts is greater than the preset number of broadcasts. When the preset number of broadcasts is reached, stop broadcasting the device search information. When the number of broadcasts has not reached the preset number of broadcasts, control the number of broadcasts of the device search information to increase by one, and broadcast the device search information with the adjusted number of broadcasts through the near-field communication method, and broadcast the device search information with the adjusted number of broadcasts to other roadside devices through the Internet. In this process, a preset number of broadcasts needs to be determined in advance. The preset number of broadcasts can also be loaded in the device search information. At this time, the preset number of broadcasts can be configured by the target system itself, or the preset number of broadcasts can be pre-configured in the roadside device. At this time, by querying the local data of the roadside device, the preset number of broadcasts can be obtained. After determining the preset number of broadcasts, continue to parse the device search information to obtain the number of broadcasts of the device search information that has been broadcast (the number of broadcasts of the device search information increases by one each time it is broadcast), and compare the number of broadcasts with the preset number of broadcasts. When the number of broadcasts reaches the preset number of broadcasts, it indicates that the number of broadcasts of the device search information has reached the upper limit, and there is no need to continue broadcasting the device search information. At this time, the device search information can be deleted from the roadside device. When the preset number of broadcasts is not reached, the number of broadcasts of the device search information can be controlled to increase by one and then continue to broadcast the device search information. In this way, it is possible to prevent the roadside device or the mobile device from broadcasting the device search information without limit.

[0056] In addition to restricting the broadcast times of the device search information by presetting the broadcast times, the broadcast duration of the device search information can also be restricted. At this time, after obtaining the device search information, the device search information can be parsed to obtain the broadcast cut-off time of the device search information, or the broadcast duration and the broadcast start time. It is determined whether the current time reaches the broadcast cut-off time, or whether the time difference between the broadcast start time and the current time reaches the broadcast duration. If the broadcast cut-off time is reached, or the broadcast duration is reached, the broadcast of the device search information is stopped. If the broadcast cut-off time is not reached, or the broadcast duration is not reached, the device search information is broadcast by means of near-field communication and the device search information is broadcast to other roadside devices through the Internet. In this embodiment, the target system can pre-configure the broadcast cut-off time, or the broadcast duration and the broadcast start time in the device search information, and restrict the broadcast mode of the device search information through the broadcast cut-off time, the broadcast duration and the broadcast start time, so as to prevent the roadside device or the mobile device from broadcasting the device search information without limit.

[0057] Corresponding to the above method for finding the coordinates of a terminal device applied to a roadside device, the present application also discloses a method for finding the coordinates of a terminal device applied to a mobile terminal. The two cooperate with each other to realize the finding of the coordinates of the terminal device. See Figure 2 ,which may include:

[0058] Step S201: Obtain device search information by means of near-field communication.

[0059] In this step, the device search information obtained by the mobile device may be the device search information sent by the roadside device or the mobile device by means of near-field communication. Similarly, the device search information at least includes the device identifier of the target device to be searched.

[0060] Step S202: Determine whether the device identifier of the mobile device is the same as the device identifier in the device search information.

[0061] When the mobile device obtains the device search information, the device identifier of the mobile device is extracted from the device search information and the local area of the mobile device, and the device identifier obtained from the local area of the mobile device is compared with the device identifier extracted from the device search information to determine whether the two are the same. If they are the same, step S203 is executed; if they are different, step S205 is executed.

[0062] Step S203: If they are the same, generate response information.

[0063] In this step, when the device identifier locally obtained by the mobile device is the same as the device identifier extracted from the device search information, it indicates that the mobile device is the target device to be searched by the target system. At this time, the response information is generated, and the response information at least includes the address information of the mobile device and the device identifier of the mobile device.

[0064] Step S204: Broadcast the response information to the roadside device by means of near-field communication. The response information at least includes the address information of the roadside device and the device identifier of the roadside device.

[0065] When generating the response information, broadcast the response information to the roadside device by means of near-field communication to send the response information to the roadside device. After obtaining the confirmation information fed back by the roadside device, stop broadcasting the response information.

[0066] Step S205: Broadcast the device search information by means of near-field communication.

[0067] In this embodiment, when the device identifier locally obtained by the mobile device is different from the device identifier in the device search information, it indicates that the current mobile device is not the target device to be searched by the target system. At this time, the mobile device can be controlled to broadcast the device search information by means of near-field communication. In this way, the device search information is broadcast to other mobile devices and roadside devices by the mobile device.

[0068] In this embodiment, the roadside device may obtain the same device search information multiple times. If the comparison of the device identifier is performed every time the device search information is obtained, it will cause the mobile device to perform meaningless analysis actions repeatedly. Therefore, in this embodiment, after obtaining the device search information, it further includes: determining whether the device search information has been executed within a preset time period. When the device search information has been executed, there is no need to perform the comparison and analysis of the device identifier, and directly execute the action: broadcast the device search information by means of near-field communication or not respond to the device search information; when the device search information has not been executed, it indicates that the mobile device obtains the device search information for the first time, and continue to execute the action: determine whether the device identifier of the mobile device is the same as the device identifier in the device search information and subsequent actions.
