Urban rail transit platform screen door interface simulation sand table

Abstract

The invention relates to the technical field of rail transit teaching and training, and particularly relates to an urban rail transit platform screen door interface simulation sand table. The urban rail transit platform screen door interface simulation sand table comprises a micro control unit MCU, wherein the micro control unit MCU is connected with a door opening relay KMJ, a door closing relayGMJ, a screen door relay C&LJ, a screen door relay REMJ, a threshold switch, a power supply module, a control button of the door opening relay KMJ, a control button of the door closing relay GMJ and an OLED module, and further comprises a relay control positive power supply KZ, a relay control negative power supply KF, interlocking equipment, a screen door simulation module, a door closing lockingrelay PDKJ and a door cutting interlocking relay PDQCJ, wherein the door opening relay KMJ is connected with a door opening indicating lamp LED1, the door closing relay GMJ is connected with a door closing indicating lamp LED2, the door closing locking relay PDKJ is connected with a closing and locking indicating lamp LED3, the door cutting interlocking relay PDQCJ is connected with a cutting interlocking indicating lamp LED4, and the door opening relay KMJ and the door closing relay GMJ are connected in series.

Description

technical field [0001] The invention relates to the technical field of rail transit teaching and training, in particular to a simulated sand table for an interface screen door of an urban rail transit platform. Background technique [0002] The existing rail transit station screen door simulation device is used to simulate the safety circuit of the door machine of the screen door of the rail transit station, the door opening command and the door closing command issued by the screen door platform controller PEDC to the door body, and simulate the door status indicator light when the door is opened. The door status indicator light flashes after the door close command is issued, and the door status indicator light goes out after the simulated safety circuit is connected. The device can demonstrate the relationship between the door status indicator light, the door open and close command, and the safety circuit. The device is shielded from the urban rail transit platform. The com...

Problems solved by technology

[0003] However, the current urban rail transit platform screen door door machine simulation device uses the delay function of the time relay to simulate the closing process of the screen door and control the flashing effect of the lights, which will add an additional circuit to the screen door interface circuit, which is not conducive to reproducing the pass signal The interface circuit and circuit parameters passed after the PSD control command is issued are not conducive to visually displaying the PSD interface circuit in training and teaching
