Abstract
The utility model discloses an urban rail transportation platform screen door communication-signal command simulation device, which is used for finding fault doors during withdrawal of trains after screen doors of a rail transportation station frequently have safety circuit disconnection faults, and is capable of accurately finding sliding doors with the safety circuit disconnection faults. The device is capable of simulating a communication-signal system to send out door opening and closing commands after subways are withdrawn, and can stop sending out the door opening and closing commands and send out alarm by the aid of a buzzer when safety circuits have no high level after certain door opening and closing circulation. At the moment, all the sliding doors can be bypassed to the safety circuits one by one. When a certain sliding door is bypassed to the corresponding safety circuit, the whole side of the safety circuit is high in level, which indicates that electrical elements such as a connector, a lead, a limit switch and the like of the safety circuit of the sliding door fail, and electrical faults of the limit switch and the like need to be checked one by one to eliminate disconnection faults of the whole side of the safety circuit of the screen door. The device is convenient in use and is capable of rapidly positioning electrical fault points resulting in the safety circuit disconnection faults.
