电缆隧道抢修人员安全监测定位及图像回传系统设计

Design of Safety Monitoring, Positioning and Image Transmission System for Cable Tunnel Repair Workers

针对电缆隧道内环境复杂、地面安全监测定位以及图像回传方式在电缆隧道内受限等问题,提出一种有线与无线相结合的隧道内外信息通信方式,并在此基础上研究设计了电缆隧道抢修人员安全监测定位及图像回传系统。文章介绍了该系统的整体拓扑结构,分析了人员定位、安全监测、图像回传等功能模块的关键技术和工作过程。应用效果表明,该系统可快速部署且终端设备简单便携,不仅可用于解决电缆隧道内作业人员的安全监测问题,同时也可为其他电力施工的安全监测提供参考。

The environment of cable tunnel is complicated, and the traditional safety monitoring, positioning and image transmission system is limited in cable tunnel. To solve the problem, a communication method integrating wire communication with wireless communication is proposed in this paper. On this basis, the safety monitoring, positioning and image transmission system for cable tunnel repair workers is studied and designed. The system topology is described, then key technologies and working process of function modules such as personnel positioning, security monitoring and image transmission are analyzed. The application result shows that the proposed system is simple and portable, and can be implemented rapidly. It can not only be used to solve the problem of safety monitoring of cable tunnel workers, but also to provide reference for other power construction conditions.
