Remote signaling anti-maloperation locking method and device based on signal power supply monitoring

The invention relates to a remote signaling anti-misoperation locking method and device based on signal power supply monitoring. A special remote signaling input terminal is set to access a remote signaling signal power supply as the monitoring of the remote signaling signal power supply, the discrimination of all external remote signaling displacements is instantaneously locked after the disappearance of the remote signaling signal power supply is recognized, the current remote signaling state is kept unchanged, and after the telecommand signal power supply is recovered, the judgment of external telecommand displacement is instantly opened, so that the problem of telecommand maloperation signals caused by telecommand signal power supply faults is solved. 本发明涉及一种基于信号电源监视的遥信防误动闭锁方法及装置，通过设置专用的遥信开入端子接入遥信信号电源正作为遥信信号电源的监视，在识别到遥信信号电源消失后瞬时闭锁所有外部遥信变位的判别，保持当前遥信状态不变，在遥信信号电源恢复后瞬时开放外部遥信变位的判别，从而解决了遥信信号电源故障造成遥信误动信号的问题。
