跨越架状态监测系统及其数据无线传输
|
摘要
为了降低输电线路跨越架线施工的安全风险,研制出智能监测系统,对跨越架的各种状态参量进行实时监测和预警。在该系统中,各监测点的监测数据采用无线通信方式传输到地面移动监测设备进行处理并显示,并基于WiFi和无线中继技术扩大了无线信号的覆盖范围。阐述了监测数据采集和无线传输的过程,以及移动监测设备数据处理软件的结构。现场实验证明,该系统能准确地监测跨越架状态的变化情况。
In order to reduce the safety risk in the construction of cross power transmission line,an intelligent monitoring system is designed to monitor various state parameters of crossing frame and to early warn the possible crises. In this system,the monitored data is transmitted to the ground mobile monitoring equipment to process and display through wireless communication mode,and the WiFi and wireless relay technology are used to expand the coverage of wireless signal. And data acquisition and wireless transmission process together with and the structure of data processing software for the mobile monitoring device are expounded. Field experiments show that changes in the state of the cross frame can be monitored accurately by the system.
