[0013] Preferably, it also includes a control module, the vehicle client initiates a positioning request to the server, and transmits the positioning request to the server through the wireless communication module, the server receives the positioning request through the data receiving module, the control module adds the positioning request to the request queue, and the vehicle client and the server maintain a continuous connection by continuously sending "heartbeats".

[0014] Preferably, it also includes a positioning calibration module, which is connected to the vehicle positioning calculation module. After the connection between the vehicle client and the server is established, the vehicle client sends GPS location data and real-time location image data to the server, and the server data receiving module receives the relevant location data of the vehicle. The vehicle positioning calculation module performs positioning calculation based on the GPS location data, and then calibrates the positioning calculation result based on the real-time location image data.

[0015] Preferably, the specific process of the positioning calibration module calibrating the positioning calculation results based on the real-time position image data is to extract feature information of the spatial dimension from the real-time position image data, and perform image feature enhancement processing on the extracted spatial dimension feature information based on image preprocessing, edge detection and contour detection, and calibrate the positioning calculation results based on the feature information of the spatial dimension in the image data after the image enhancement processing.

[0016] Preferably, while the vehicle client initiates a positioning request to the server, the vehicle client will send other requests. The control module will add the requests to the request queue in sequence according to the time when the requests were initiated.

[0021] Preferably, after the destination vehicle client obtains the TCP or UDP data packet, the TCP or UDP data packet is decapsulated, the TCP or UDP header is removed, and the TCP or UDP data is passed to the designated application.

[0022] The beneficial effects of the present invention include:

[0023] The small server for real-time vehicle positioning provided by the present invention comprises a data receiving module, a database module, a wireless communication module, a vehicle positioning calculation module, a map generation module, and a service website module. The data receiving module receives relevant position data and request data of the vehicle; the wireless communication module realizes wireless communication between the vehicle and the server; the database module stores relevant position data and user information of the vehicle to prepare data for subsequent vehicle search guidance; the vehicle positioning calculation module calculates the real-time positioning of the vehicle based on the GPS positioning data and real-time position image data of the vehicle; the map generation module generates vehicle travel map data based on the real-time positioning result of the vehicle calculated by the vehicle positioning calculation module; and the service website module visually displays the vehicle travel map data generated by the map generation module.

[0024] First, the server and the vehicle client realize wireless communication based on the global mobile communication system GSM protocol or GPRS protocol or TCP / IP protocol, and realize data security, efficient and stable transmission through the data segmentation and splicing, data encryption and decryption of the GPRS protocol. The wireless communication method through the TCP / IP protocol supports flexible routing selection, so that data can be transmitted to the destination quickly and accurately.

[0025] Secondly, the vehicle client initiates a positioning request to the server, and transmits the positioning request to the server through the wireless communication module. The server receives the positioning request through the data receiving module, and the control module adds the positioning request to the request queue. The vehicle client and the server maintain a continuous connection by continuously sending "heartbeats", so that the real-time location data can be processed in real time, preventing delays in location data processing.

[0026] Again, by setting up a positioning calibration module, the vehicle client sends GPS location data and real-time location image data to the server, and the server data receiving module receives the relevant location data of the vehicle. The vehicle positioning calculation module performs positioning calculation based on the GPS location data, and then calibrates the positioning calculation result based on the real-time location image data, thereby further improving the accuracy and precision of real-time positioning.

[0027] Finally, while initiating a positioning request to the server through the vehicle client, the vehicle client will send other requests and add the requests to the request queue in sequence. The control module assigns priorities to all requests in the request queue and reorders the order of the request queue based on the assigned priorities to form a new request queue, in which the positioning request is at the first priority, ensuring that the real-time location data can be processed first and the real-time nature of the location is ensured.
