Abstract

The utility model discloses a PEDC test-bed for a screen door platform controller of an urban rail transit platform, which can demonstrate and simulate the dual-switching contact actions of the opening and closing the screen door and truly repeats the safe circuit breaking within a certain time after the open-door command is emitted and the safe circuit closing within a certain time after the close-door command is emitted; the duration of the open-door command and the duration of the close-door command are adjustable, namely the door opening and closing frequency and duty cycle can be changed;and a safe circuit high level triggers a counter to act, thus detecting and testing service life of the PEDC of the screen door platform controller. The test-bed has the beneficial effects that the level rule of open-door and close-door commands can be simulated, namely the open-door command and the close-door command can not be 1 simultaneously, the open-door command and the close-door command can not be 0 simultaneously; the close-door command is 0 when the open-door command is 1; and the close-door command is 1 when the open-door command is 0. When the safe circuit level is 1, the counterincreases 1, therefore, the PEDC of the screen door platform controller can be detected and the service life thereof can be tested, thus being able to disconnect the electric and mechanical system ofthe screen door of the station platform, thereby repeating the open-door and close-door commands of the screen door and the safe circuit level. At present the screen door system based on the screen door opening and closing and safe circuit control principle related to the device is installed in the cities such as Beijing, Shanghai, Guangzhou, Shenzhen, and the like. The PEDC test-bed can be used as a demonstration tool for repairing and maintenance training and teaching of the screen door, and can be taken as an auxiliary tool for improved design of the screen door.
