Description

Technical Field

[0001] The utility model relates to the field of rail transportation, in particular to a CBTC door controller test bench. Background Art

[0002] Door controllers, installed within subway train cars, are core components for controlling the movement of subway train doors and are crucial for ensuring the proper operation and safety of subway trains. During subway train operation, door controller failures cannot be tested, making fault diagnosis difficult. These devices must be sent to the manufacturer for repair, resulting in long repair cycles and high costs, impacting the normal operation of subway trains. Door controller testing locations are limited, requiring on-site testing within the train car. Testing typically requires installing the door controller on a door and starting the vehicle to test its effectiveness. Therefore, existing technologies use door controller test benches to test the door controller's status. These test benches connect to the door controller and test its status by sending control signals to it and receiving drive signals from it. However, with the upgrade of subway trains to CBTC (Computer-Based Trading Platform), existing door controller test benches can only test the door controllers of a single vehicle type and are unable to test the upgraded CBST (Centralized Bitcoin Transport) vehicle type. Existing door controller test benches also cannot test the door controller's alarm circuit or its energy consumption. In traditional testing, the door controller test bench is directly connected to the busbar in the door controller's aviation plug, which can easily cause pin shrinkage and oxidation of the door controller's aviation plug.
