The utility model provides a nuclear power intelligence integrated control cabinet, including the cabinet body, internal host system and the spare module of being equipped with of cabinet, host system and spare module are connected with the input and output interface respectively, and host system and spare module are the same CPU, move the same control program, host system and spare module are kept apart at the internal mutual physics of cabinet, the electric isolation, connect through fiber communication between host system and the spare module. The utility model discloses an industrial computer has replaced traditional electrical components, and cabinet body size reduces a lot, nor can damage like traditional electrical components, realized intelligent, long -rangeization control, real -time supervision, record heating system's operating condition and data can the fast switch overs when break down, are that the system stablizes more, safety, use ethernet communication distance is far away, anti -electromagnetic interference can the reinforce, software system upgrades conveniently, and it is convenient that control module dismantles, maintains.
