Multifunction logic processing system and operation mode thereof

The invention discloses a multifunction logic processing system which comprises a signal processor CPU, wherein the front end of the signal processor CPU is connected with a signal input module, and the rear end is connected with a signal output module; the signal input module is connected with a high-voltage equipment control unit; the signal output module is connected with the controlled high-voltage equipment unit; the signal input module comprises a signal button; the signal output module comprises an indicating lamp module and a brake opening and closing module; the signal processor CPU comprises a logic analysis module, a storage module, a communication module, a mode conversion module and a brake opening state detection module. The system disclosed by the invention has the following advantages: mutual signal interference leading to the failure of meter reading or remote brake opening is prevented, and a situation that two modules are burnt at the same time due to the line fault is avoided; complicated
