Platform door control system with safety backup output capability

Abstract

The invention discloses a platform door control system with safety backup output capability, and belongs to the technical field of rail transit, the state of a core module is detected, and if the state of the core module is normal, a control signal is processed based on a first control rule to generate a first control instruction; if the state of the core module is abnormal, the control signal is firstly processed based on a second control rule, then the processed control signal and the station door state information are compared and evaluated, a second control instruction is generated based on the evaluation result, and the station door is controlled according to the first control instruction or the second control instruction. Through a double-layer control mechanism of the core module and the interface module, redundancy processing of control signals is ensured; and if the core module is abnormal, the interface module can continuously process the control signal based on the second control rule, so that the system is prevented from comprehensively losing efficacy due to a single fault point, and the timeliness and the reliability of platform door control are improved.
