防止吊车触碰高压输电线的报警装置研制

Development of Alarming Device against Crane Contact with HV Transmission lines

介绍高压输电线下防施工吊车碰线报警器的研制,报警器通过无线方式接收施工车吊车多个电场感应器和超声波探测器的测量数据,根据测量信号作出安全、预警、高压报警和线路距离的报警提示。

This paper introduces the research and development of the anti-crane contact alarming device under high-voltage transmission lines.The alarming device can receive wirelessly all the signals sent by the various electric-field sensors of the crane and the measurement data sent by the ultrasonic detection,and then the device can give out different indications about safety,precaution,high-voltage danger and distance warning accordingly so as to protect the high-voltage transmission line from careless damage of the working cranes.
