On-line Active Safety Warning Monitoring System of Power Equipment by Microwave Induction

For the deficiency of the passive warning manner of safety warning sign around the high voltage power system and a lot of electric power equipments are stole, we developed a on-line active safety warning monitoring system of power equipment by microwave induction, the device adopts microwave sensor technology to monitor the room around power equipment. When there is some objects are moving to it, the safety and warning system will capture signal of the object, and start alarm to warn who is near the high voltage danger zone. Two kinds of alarm have been certain by the operator in advance. The first grade will turn on when some people have been in dangerous areas which have been set by the managers. The second grade will be much more useful than the first, especially when some one wants to thieve electric power equipments, it will send short message to the monitor center. Thus the center can call the duty men who take charge of the thieving electric power equipments in time. In this way we can manage all the electric power equipments more successfully. This paper discusses the operating principles, design methods. Through a lot of field tests, the device could be effectively to warn people who are within 8 meters from the high danger zone.
