The traditional fire warning method has the problems of high false alarm rate and slow response speed.Therefore,a SCM based automatic fire warning method for high-voltage cable channel in substations is proposed.Design a fire sensor based on a SCM.When the data exceeds the preset safety range,the SCM will determine that a fire has occurred,collect and process fire signals in the cable trench,and when smoke is detected,the SCM will convert it into a signal for recognition,achieving automatic fire warning of high-voltage cable channel in substations.The results show that the automatic fire warning method for high-voltage cable channels in substations based on SCM can effectively monitor the volume fraction of carbon monoxide during a fire and issue an alarm in a timely manner,proving that this method can effectively achieve the fire warning function.
