Abstract
A relay control apparatus according to an embodiment of the present disclosure includes a processor configured to output a basic control signal for controlling an operation of a relay and a recovery signal having a differential signal level according to a recovery state thereof; a monitoring unit configured to monitor an operation state of the processor and output a decision-control signal having a differential signal level according to the operation state of the processor and a retain signal for maintaining the operation state of the relay; and a relay state determining unit configured to output one of the basic control signal and the retain signal as a relay control signal for controlling on/off of the relay based on the signal level of the decision-control signal or the recovery signal.
Claims20
A relay control apparatus, comprising:
- a processor configured to output a basic control signal for controlling an operation of a relay and a recovery signal having a differential signal level according to a recovery state thereof;
- a monitoring unit configured to monitor an operation state of the processor and output a decision-control signal having a differential signal level according to the operation state of the processor and a retain signal for maintaining the operation state of the relay;
- and
- a relay state determining unit configured to output one of the basic control signal and the retain signal as a relay control signal for controlling on/off of the relay based on the signal level of the decision-control signal or the recovery signal.
A relay control method, comprising:
- a basic signal receiving step of receiving a basic control signal for controlling an operation of a relay and a recovery signal having a differential signal level according to a recovery state of a processor;
- a control signal receiving step of receiving a decision-control signal having a differential signal level according to an operation state of the processor and a retain signal for maintaining an operation state of the relay;
- and
- a control signal output step of outputting one of the basic control signal and the retain signal as a relay control signal for controlling on/off of the relay based on the signal level of the decision-control signal or the recovery signal.
