[0002] In the field of vehicle inspection, it is crucial to ensure that vehicles undergo real and effective inspections at designated inspection agencies. With the continuous increase in the number of cars on the road, the demand for vehicle inspections is growing. However, violations such as vehicle substitution inspections occur from time to time. Substitution inspections not only violate relevant regulations on vehicle inspections, but may also result in vehicles that do not meet safety standards being on the road, posing serious hidden dangers to road traffic safety. At present, vehicle inspections mainly rely on inspection agencies to test various performance indicators of vehicles and record inspection information through inspection terminals. However, in the actual inspection process, due to the lack of effective supervision measures, it is difficult to ensure that the vehicle has actually completed the inspection process at the inspection agency, nor can it ensure the true correspondence between the inspection data and the actual inspected vehicle. Therefore, it is necessary to provide a vehicle anti-substitution inspection early warning method and system based on electronic maps and positioning data to solve the above problems.

[0060] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0061] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0062] like Figure 1As shown, an embodiment of the present invention provides a vehicle replacement inspection warning method based on an electronic map and positioning data, the method comprising the following steps:

[0063] S100, receiving the location information and VIN code uploaded in real time by the vehicle GPS terminal, and comparing the location information with the location area of ​​the inspection agency;

[0064] S200, when the location information is within the location area of ​​the detection mechanism, turning on the vehicle Bluetooth, and determining the vehicle coordinate information based on the Bluetooth beacon deployed in the detection mechanism, the vehicle coordinate information including the vehicle coordinates at each moment;

[0065] S300, transmitting vehicle parameter information and VIN code via Bluetooth, wherein the parameter information includes parameter items, parameter values, and corresponding time;

[0066] S400, receiving vehicle inspection information uploaded by the inspection terminal, wherein the vehicle inspection information includes the terminal number, inspection item, VIN code, inspection start and end time, and inspection result;

[0067] S500, comparing the vehicle coordinate information with the corresponding vehicle detection information to determine whether the vehicle is in the corresponding detection area during the detection period;

[0068] S600: Compare the parameter information with the corresponding vehicle detection information to determine whether the parameter change of the vehicle matches the corresponding detection item.

[0069] It should be noted that it is difficult for traditional vehicle detection methods to accurately determine whether the vehicle actually being detected is the vehicle to be inspected. There is a risk of vehicle substitution for inspection, and the authenticity and validity of the detection results cannot be guaranteed. Relying solely on the location information uploaded by the vehicle's GPS terminal, it is difficult to accurately determine the specific location of the vehicle within the detection agency, and it is impossible to effectively determine whether the vehicle is being tested within the specified detection area. In addition, during the detection process, there is a lack of effective verification means for the relationship between vehicle parameter changes and detection items, making it difficult to determine whether the detection results truly reflect the actual conditions of the vehicle under the corresponding detection items, which may lead to inaccurate detection results. The embodiments of the present invention are intended to solve the above problems.

[0070] In an embodiment of the present invention, first, the vehicle needs to continuously upload location information 24 hours before the detection, and then the location information will be compared with the detection agency location area in the electronic map. When the location information is within the detection agency location area, it means that the vehicle has entered the detection agency and is ready for detection. Then, the vehicle-mounted Bluetooth is turned on, and the vehicle coordinate information is determined based on the Bluetooth beacon deployed in the detection agency. Multiple Bluetooth beacons need to be installed in the detection agency in advance, and the spacing between the beacons is preferably around 10-20 meters. In this way, the specific location of the vehicle in the detection agency can be accurately determined. In addition, a backend server is also arranged in the detection agency. The backend server has a Bluetooth connection function and a large transmission power, which supports long-distance transmission. In this way, the parameter information and VIN code of the vehicle can be transmitted via Bluetooth. The parameter information includes parameter items, parameter values ​​and corresponding time. For example, the parameter items include engine speed, vehicle speed, etc. Every time the vehicle performs a test, the corresponding detection terminal will upload the vehicle detection information. The vehicle detection information includes terminal number, test item, VIN code, detection start and end time, and test result. Then, by comparing the vehicle coordinate information with the corresponding vehicle detection information, it is possible to accurately determine whether the vehicle is in the corresponding detection area during the detection period, ensuring that the vehicle is detected within the specified detection area. Further, the parameter information will also be compared with the corresponding vehicle detection information to determine whether the parameter changes of the vehicle match the corresponding detection items, thereby verifying whether the detection results truly reflect the actual conditions of the vehicle under the corresponding detection items, and improving the accuracy of the detection results. The embodiment of the present invention receives the position information and VIN code uploaded by the vehicle GPS terminal in real time, and compares it with the detection agency location area, combines the vehicle-mounted Bluetooth with the Bluetooth beacon deployed in the detection agency to determine the vehicle coordinate information, and transmits the parameter information and VIN code of the vehicle via Bluetooth, and performs multi-dimensional comparison with the vehicle detection information uploaded by the detection terminal, and performs cross-verification. It can accurately determine whether the vehicle actually being detected is the vehicle to be inspected, effectively prevent the occurrence of vehicle replacement inspection behavior, and ensure the authenticity and validity of the detection results.

[0071] like Figure 2 As shown, as a preferred embodiment of the present invention, the step of determining the vehicle coordinate information based on the Bluetooth beacon deployed in the detection mechanism specifically includes:

[0072] S201, continuously receiving a signal sent by a Bluetooth beacon in a detection mechanism based on the vehicle-mounted Bluetooth, and recording an identifier of the received beacon and a corresponding signal strength value;

[0073] S202, transmitting a plurality of identifiers and corresponding signal strength values ​​to a backend server, analyzing each signal strength value, and determining the distance between the vehicle and each Bluetooth beacon;

[0074] S203, retrieve the beacon coordinates corresponding to each identifier, and obtain vehicle coordinate information based on a triangulation positioning algorithm.

[0075] In an embodiment of the present invention, the vehicle-mounted Bluetooth continuously receives signals sent by the Bluetooth beacon in the detection mechanism and records the identifier of the received beacon and the corresponding signal strength value (RSSI). Then, several (at least three) identifiers and corresponding signal strength values ​​are transmitted to the background server. The background server analyzes each signal strength value to determine the distance between the vehicle and each Bluetooth beacon. Here, a distance path loss model of the signal strength is constructed in advance. Finally, the vehicle coordinate information is obtained based on the triangulation positioning algorithm. When the identifiers and corresponding signal strength values ​​exceed three groups, they are permuted and combined to calculate the vehicle coordinates in all cases, and the coordinate average is finally taken.

[0076] like Figure 3 As shown, as a preferred embodiment of the present invention, the step of comparing the vehicle coordinate information with the corresponding vehicle detection information to determine whether the vehicle is in the corresponding detection area during the detection period specifically includes:

[0077] S501, retrieve all vehicle coordinates within the corresponding time according to the VIN code and detection start and end time in the vehicle detection information to obtain a vehicle coordinate set;

[0078] S502, retrieve the corresponding detection area according to the terminal number in the vehicle detection information;

[0079] S503: Compare the vehicle coordinate set with the detection area. When a vehicle coordinate exceeds the detection area, the vehicle is not in the corresponding detection area during the detection period.

[0080] In this embodiment of the present invention, to ensure that the corresponding vehicle is within the detection area during the detection period, the coordinates of all vehicles within the corresponding period are retrieved based on the VIN code and the detection start and end times. This vehicle coordinate set is then obtained, and the corresponding detection area is retrieved based on the terminal number. Finally, the vehicle coordinate set is compared with the detection area. If any vehicle coordinates exceed the detection area, it indicates that the vehicle was not within the corresponding detection area during the detection period. In this way, it is possible to accurately determine whether the vehicle is within the corresponding detection area during the detection period, ensuring that the vehicle is detected within the specified detection area.

[0081] like Figure 4 As shown, as a preferred embodiment of the present invention, the step of comparing the parameter information with the corresponding vehicle detection information to determine whether the parameter change of the vehicle matches the corresponding detection item specifically includes:

[0082] S601, retrieve parameter items and parameter values ​​within the corresponding time according to the VIN code and detection start and end time in the vehicle detection information;

[0083] S602, drawing an actual parameter change curve corresponding to the vehicle based on the parameter items and parameter values;

[0084] S603, retrieving a theoretical parameter change curve according to the detection items in the vehicle detection information;

[0085] S604 , performing similarity matching between the actual parameter change curve and the corresponding theoretical parameter change curve to determine whether the parameter change of the vehicle is consistent with the corresponding detection item.

[0086] In an embodiment of the present invention, in order to determine whether the vehicle has been tested for the corresponding project, the parameter items and parameter values ​​within the corresponding time will be retrieved according to the VIN code and the start and end time of the test, and then the actual parameter change curve of the corresponding vehicle will be drawn, for example, the actual parameter change curve includes the engine speed curve. Then, the theoretical parameter change curve is retrieved according to the test item. The theoretical parameter change curve of each test item needs to be formulated in advance. For example, during exhaust gas testing, the theoretical engine speed curve will be increased from idle speed (800±100rpm) to test speed (2500±200rpm) within 5 seconds after the start of the test. Finally, the actual parameter change curve and the corresponding theoretical parameter change curve are matched for similarity. Here, a curve graph similarity calculation formula (such as Pearson correlation coefficient, cosine similarity) can be used. When the similarity is higher than a set threshold, it is determined that the parameter change of the vehicle is consistent with the corresponding test item; when it is lower than the set threshold, it does not meet the requirements.

[0087] like Figure 5 As shown, as a preferred embodiment of the present invention, the method further includes:

[0088] S701, when the vehicle is not in the corresponding detection area during the detection period, or the parameter change of the vehicle does not match the corresponding detection item, generate a warning message;

[0089] S702, recording the VIN code of the corresponding vehicle and adding the VIN code to the video surveillance detection list;

[0090] S703: Receive re-detection information corresponding to the vehicle, where the re-detection information is bound to the full-process monitoring video.

[0091] In this embodiment of the present invention, it is easy to understand that if a vehicle is not in the corresponding inspection area during the inspection, or if the vehicle parameter changes do not match the corresponding inspection items, an early warning message is generated, indicating that the inspection has failed. At this time, the corresponding vehicle's VIN code is recorded and added to the video surveillance inspection list. This indicates that when the vehicle is re-inspected, in addition to uploading the re-inspection information, a full surveillance video is required, and the full surveillance video must include specific footage of each inspection.

[0092] like Figure 6 As shown, an embodiment of the present invention further provides a vehicle replacement inspection warning system based on electronic maps and positioning data, the system comprising:
