This application discloses a method and system for preventing dragging of rail transit vehicle doors based on contact-type sensitive edge resistance detection. The method includes: acquiring train zero-speed signals, door closing and locking status signals, and isolation status signals; and using a controller to determine whether to activate sensitive edge detection based on the combined logic of the acquired signals. When sensitive edge detection is activated, the controller detects the resistance change of the sensitive edge, and converts the detected sensitive edge resistance signal into a voltage signal via a resistance sampling circuit inside the controller. The voltage value corresponding to the converted voltage signal is used as a decision variable. If the decision variable corresponding to the sensitive edge meets a first preset condition, it is determined that the sensitive edge has been triggered and an object is being clamped. The controller then controls the disconnection of the safety relay contacts to cut off the train traction circuit, and simultaneously triggers an alarm device to issue an audible and visual warning signal. This application can reliably identify and lock soft, thin objects clamped by the vehicle, eliminating the risk of dragging.
