中文摘要:

      随着智能电网和小尺度雷电预警技术在电力系统的推广和应用，如何在工程实施时选择合适的安装点是迫切需要解决的问题。为了提高现场电场仪选址的有效性，设计与开发了一种主要由探头传感及支撑部分（终端节点）和无线手持终端设备（协调器）两部分组成的便携式电场仪选址系统。本系统终端节点的探头传感部分包括电场探测功能、供电功能、短距离无线收发功能，其支撑部分采用具有多级收缩功能的支撑架，便于携带和安装；手持终端（协调器）采用无线短距离的ZigBee通信技术进行现场测量数据的传输，并在终端设备存储及图形显示电场数据。本系统可以同时接收同一区域的两个监测点的电场测量数据，通过两监测点的数据拟合对比来获得现场环境系数，为提高雷电预警系统的准确率有很大的意义。

英文摘要:

      With the promotion and application of the smart grid and the small scale lightning warning technology in the power system,how to choose the appropriate installation point is the urgent problem to be solved for the implementation of the project.A portable electric device of location system is designed and developed to improve the effectiveness of the electric device on site,which includes the probe sensor and the support part (terminal node) and wireless hand-held terminals (the coordinator).Probe sensor part of the terminal node consists of electric field detection,power supply and short distance wireless transceiver functions,the support part of the terminal node adopts brace with multi-stage systolic function,easy to carry and install.The short ZigBee wireless communication technology of hand-held terminals (coordinator)is adopted to improve the field measurement data transmission,and storage and graphics display field data in the terminal equipment.In this system,the data of electric field measurement can be simultaneously received from the two monitoring site in the same area,the environmental factor can be gotten by fitting and comparing the data of the monitoring points,and which has great significance for improving the accuracy of lightning warning system.
