提升山区无线信号强度测量准确性的应用研究

Application Research on Improving the Measurement Accuracy of Wireless Signal Intensity in Mountainous Areas

山区配电自动化建设布点中最大难题在于无线4G信号强度的测量,尤其是在云南多山地区,手机难以精确测量出4G无线信号强度,且测量结果偏差大,导致在后期应用过程中出现主站无法远程遥控智能断路器、终端无法把三遥数据上传至主站,最终导致二次迁改安装。为了进一步提升4G信号强度测试准确性,提出了一种新的山区无线4G信号强度测试方法,该方法基于配电自动化终端加密网关运行数据来判断无线4G信号强度,准确测量出山区智能断路器布点位置无线信号强度,为后期配电自动化实用化应用提供保障。

The biggest problem in distribution automation construction in mountainous areas is the measurement of wireless 4G signal strength.Especially in the mountainous areas of Yunnan,it is difficult for mobile phones to accurately measure the 4G wireless signal strength,and the measurement results deviate greatly.Especially in the mountainous areas of Yunnan,it is difficult for mobile phones to accurately measure the 4G wireless signal strength,and the measurement results deviate greatly.As a result,in the later application process,smart circuit breakers in the main station cannot be remotely controlled,and terminals cannot upload the three-remote data to the main station,which ultimately leads to secondary relocation and installation.In order to further improve the accuracy of 4G signal strength test,a new method of wireless 4G signal strength test in mountainous area is presented.This method judges the wireless 4G signal strength based on the operation data of the terminal encryption gateway of the distribution automation,and accurately measures the wireless signal strength of the location of the intelligent circuit breaker in the mountainous area,which provides guarantee for the practical application of the later distribution automation.
