After the baffle is damaged, the baffle is lifted up from bottom to top, the clamping groove and the clamping block are separated, the damaged baffle can be taken down from the fixing plate, a new baffle is taken up, the clamping block is aligned to the clamping groove and inserted, and the baffle can be fixed on the fixing plate again.

The invention discloses a vehicle passing method and device, computer equipment and a storage medium, and the method comprises the steps: carrying out the pre-recognition of the vehicle information of a target vehicle when the target vehicle is driven to a pre-recognition position, so as to obtain a vehicle pre-recognition result; performing pre-authentication based on the vehicle pre-identification result to obtain a first authentication result; when the target vehicle runs to the re-identification position, re-identifying the vehicle information of the target vehicle to obtain a vehicle re-identification result; and comparing the vehicle pre-identification result with the vehicle re-identification result, and when the results are consistent, performing passing processing on the target vehicle based on the first authentication result. Before the vehicle arrives at the gate, pre-identification and pre-authentication of the license plate are carried out, and if the vehicle identification result is consistent with the actual vehicle identification result, the vehicle can be released directly through the pre-authentication result, so that the vehicle passing speed is increased, vehicle congestion at the entrance and the exit is avoided, and the passing experience is improved.

The present invention provides a passenger car security inspection method, device and system. The method comprises: obtaining a license plate image and an appearance image of a passenger car; obtaining an X-ray image of the passenger car, and automatically detecting whether the passenger car has contraband; storing the license plate image, the appearance image and the detection result of the X-ray image and uploading them to a server; if the result of the automatic detection of the X-ray image is that the passenger car carries contraband, an alarm is issued. According to the present invention, it is possible to quickly check whether a passenger car has contraband while reducing manpower and physical costs.

The application discloses a traffic supervision system and method based on AI technology, which comprises a data acquisition module, a pretreatment module, a comparative analysis model, a data control module, and the comparative analysis model further comprises a data analysis unit and a data processing unit, and relates to the technical field of traffic supervision.
