Description

Technical Field

[0001] The present invention relates to the field of rail transportation, and in particular to a detection device for an external driver controller. Background Art

[0002] The driver controller is an important component for controlling the traction and braking system of subway trains during subway operation. The driver controller is the operation center of the train, allowing the train driver to control the operation of the train, including starting, stopping, speed regulation, braking and other operations. The driver controller is usually equipped with a control panel and buttons, through which the driver can control the running status of the train. Due to the complex internal structure of the driver controller, there are many contacts and the resistance value output has high accuracy. When the switches inside the driver controller are frequently operated, failures are prone to occur, which affects the punctuality and safety of passengers and has a significant impact on train operations.

[0003] In the prior art, when a driver controller fails, an external driver controller is mainly installed in the driver's cab to replace the driver controller installed in the train control console. The external driver controller is a control device attached to the outside of the subway train. When the driver controller fails, the driver can disconnect the upper power switch of the original driver controller, connect the external driver controller to the console, and replace the driver controller on the train to work. The basic train functions can be realized by operating the knob of the external driver controller to avoid rescue. In order to ensure the reliable use of the external driver controller, it is necessary to conduct regular inspections of the external driver controller. However, due to the large number of contacts and components of the external driver controller, the functional testing and inspection of its connecting wires are relatively troublesome.
