System and method for diagnosing door controller for rail transit

Abstract

The present invention discloses a gate controller diagnostic system and method for rail traffic. The system comprises a DSP and a power module, a soft start module, a watchdog module, a storage circuit, a motor drive circuit, an outlet and a key inlet which are connected with the DSP, the motor drive circuit is connected with the DSP through a current sampling device, the soft start module is connected with an external power source, the motor drive module is connected with a motor and the power module, the DSP is connected with an upper computer and a remote diagnostic system, and the power module is connected with the DSP through a voltage sampling circuit. In the working hours, the key inlet self diagnosis comprises door opening train line self diagnosis and door enabling train line diagnosis, the DSP performs diagnosis whether the power supply voltage is in a preset range or not through the voltage sampling circuit, if yes, the work goes on, and if not, the sampling voltage is compared with the locally stored power source fault information to perform offline analysis of the fault information to obtain a fault conclusion. The gate controller diagnostic system and method for railtraffic reduce the operation fault rate of the gate controller, reduce the fault analysis difficulty and make the train door operation safer.

Description

technical field [0001] The invention relates to the technical field of rail transit gate controllers, in particular to a diagnostic system and method for a rail transit gate controller. Background technique [0002] Door controllers for rail transit are mainly used in high-speed rail and urban rail. By receiving signals such as opening and closing of the vehicle door, the drive motor drives the door transmission to realize functions such as opening and closing the door. The operating status of the door has a greater impact on the safety of passengers. During the operation of the existing door controllers for rail transit, it is impossible to judge the state of the door controllers in advance. When there are faults such as the door cannot be opened or closed properly, the root cause of the fault cannot be captured in time, and the fault can only be detected. The information is reported to the vehicle control center, and the vehicle needs to return to the warehouse to reproduc...
