Rail vehicle door lock switch non-contact monitoring method and rail vehicle door lock switch non-contact monitoring device

The invention discloses a rail vehicle door lock switch non-contact monitoring method and a rail vehicle door lock switch non-contact monitoring device. The rail vehicle door lock switch non-contact monitoring device comprises a power supply module used for power supply and a switch module connected with the power supply module. The rail vehicle door lock switch non-contact monitoring device is characterized in that a data transmission processing module is provided, and is connected with an illuminating device and an image sensor; the illuminating device and the image sensor are fixedly disposed on a vehicle door frame by fixing devices, and a door lock is provided with a mark. A non-contact sensing device adopts the non-contact image sensor having the high cost performance, which is safe and convenient, is compact in structure, and has no impact on operation of other devices. An algorithm part adopts a conventional filtering method for characteristic extraction and target detection positioning, and therefore calculated amount is small. By arranging the rail vehicle door lock switch non-contact monitoring device on a rail vehicle door system, effective data can be acquired, and a safety guarantee is provided for a rail transit system.
