Description

Detecting system and detecting method for carryover in passenger room of vehicle Technical Field The invention belongs to the technical field of rail transit. More particularly, the present invention relates to a vehicle in-cabin carryover detection system. The invention also relates to a detection method of the detection system. Background If passengers stay on the car or lose articles during taking the car of the automatic passenger shortcutting system (APM, automated People Mover System), not only can the train operation be affected to a certain extent, but also the risk of terrorist attack exists. The APM300 thus requires emptying the vehicle at the end of its operation. Because the APM300 vehicle has no driver in the running process, if the traditional manual checking of the vehicle monitoring video is adopted and workers are arranged to check the positions of the vehicle one by one in the carriage, not only is the manpower wasted and the running efficiency affected, but also the risk that the workers inadvertently generate missing reports exists. The key words such as 'vehicle; inner; left article; detection' and the like are adopted to search the prior disclosed technical literature, so that the following search results are obtained: 1. chinese patent literature is a method, a device, equipment and a readable storage medium for detecting a vehicle left-behind object, patent (application) number is 202511266661.3, and the recorded technical scheme is as follows: The method, the device, the equipment and the readable storage medium for detecting the vehicle left-behind object are applied to the technical field of vehicle left-behind object detection, and the method can be applied to vehicles. The vehicle comprises millimeter wave radar, OMS lenses, OMS lens shielding sliding blocks and a sliding block driving motor. The method includes detecting whether a left-behind object exists inside the vehicle based on the millimeter wave radar in response to an off-vehicle signal of the passenger. If yes, sending a reminding signal to the passenger. After receiving a monitoring instruction sent by a passenger, controlling a slide block driving motor to drive an OMS lens to block the slide block to move so as to leak the OMS lens, and acquiring an in-vehicle image of the vehicle by using the OMS lens. The in-vehicle image is sent to the passenger to remind the passenger that a left object is left when the passenger leaves the vehicle; the recorded technical effects are as follows: the problem that the traditional method for detecting the objects left in the vehicle has functional limitations and insufficient privacy protection is solved. 2. The Chinese patent literature is that a detection method of vehicle cabin carryover, a storage medium, electronic equipment and a vehicle, and the patent (application) number is 202310103891.2, and the recorded technical scheme is as follows: The method comprises the steps of obtaining second CSI data in a first preset time after passengers get off a vehicle through the wifi receiving and transmitting equipment; determining whether the vehicle cabin has an active legacy according to the second CSI data; the recorded technical effects are as follows: The method has the advantages that the moving legacy objects in the vehicle cabin are detected based on WiFi Channel State Information (CSI) data of the first preset time after passengers get on the vehicle, the cost is lower, the reliability is higher, an image is not generated by WiFi perception, and the method is more suitable for the scene in the vehicle with higher privacy requirements. However, the technical solutions described in the above technical documents and the related technical solutions of the existing public application are not capable of solving the problems and defects of "wasting manpower and material resources", "influencing the operation efficiency", "having a risk of inadvertently generating a report by a worker", and the like in the prior art.
