Abstract

Provided is a system self-repairing controller, comprising a power module, a dead halt signal acquisition module, a one-chip microcomputer and an outage restart module. The power portion provides a 5V power source for the dead halt signal acquisition module, the one-chip microcomputer and the outage restart module. The dead halt signal acquisition module acquires system signals and determines whether dead halt occurs or not and transmits the signals to the one-chip microcomputer through pins. The one-chip microcomputer transmits the signals to the outage restart module. When the one-chip microcomputer outputs high level, a normally closed contact on a transistor drive relay is disconnected, and a circuit is disconnected. Through software time-delay, the normally closed contact is closed, and the circuit is connected. Through the one-chip microcomputer controlling the outage restart module to perform outage restart on the system, adverse effects generated by artificial restoration are prevented, and the system self-repairing controller can effectively perform self-repairing on the system after network devices and modem crash. A repairing process can be completed in one minute. The system self-repairing controller saves manpower, and faults can be repaired immediately when faults occur. The system self-repairing controller is beneficial for stable operation of an alarm service system.
