摘要
本文介绍一种安全报警与作业监控于一体的防止吊车触电的监控系统。它利用电场感应原理和ZigBee通信技术判断吊车臂与高压输电线路之间的距离,当低于预先设定的安全距离时向车载装置发送报警信息。系统将吊车实时的位置通过简化匹配算法显示在GIS地图上,同时根据车载装置中的GPS模块发送的位置信息判断吊车与输电线路之间的距离,低于设定的保护距离时,系统通过3G/GPRS向车载装置发送语音提示,同时通过短消息向巡检人员发送消息。系统分为近电监测、车载装置以及吊车作业报警和监控系统3个部分。近电检测装置安装在吊车臂,车载装置安装在驾驶室内。实际测试表明,系统测试精度较高,满足高压输电线路下的吊车防触电保护和实时作业监控的需求。
An alarming and monitoring system is introduced to prevent crane contact with high voltage transmission lines, which determines the distance between the vehicle with the high voltage power cables by using electric field induction principle and ZigBee technology. When the distance is less than preset safe distance, it begin to send out sound alarm. The crane real-time position will be displayed the GIS map by simplify matching algorithm, and determine the distance between the crane and the transmission line based on the position information that send by GPS module in the vehicle-mounted device, when the distance is less than preset protection distance, system will to alarming information by 3G/GPRS and SMS. System divided into three parts, including electric field detection device, vehicle-mounted device and crane alarming and monitoring system, electric field detection device is mounted on crane arm and vehicle-mounted device is mounted in the cab. Practical tests show that the system has high test accuracy, it can meet crane shock protection and real-time monitoring under the high voltage transmission lines.
