摘　　要：为了实现大气电场仪的联网,分析了联网中存在的问题,主要包括单站预警方式、数据一致性以及联网算法上存在的问题。对于单站预警方式提出了改进的办法,可在单一应用预警值的基础上,增加电场跳变检测。分析了各站点数据一致性对预警网络的影响,结果显示,地面物会引起大气电场畸变,安装环境对电场仪数值影响很大。提出了解决数据一致性的途径。指出了利用电场计算电荷中心位置等雷暴参数存在的问题,给出了简化的解决方式。In order to realize constructing atmospheric electric field monitoring net, several problems in constructing atmospheric electric field monitoring net were studied, including alarm mode of single atmospheric electric field monitoring, the data＇s coherence of the atmospheric electric field monitor in the net, and the arithmetic to make the monitors work well all together. Here a method was introduced to advance the alarm mode; and the leap in atmospheric electric field curve was detected based on the atmospheric electric field alarm value. How the data＇s coherence affects the alarm of the electric field monitor net was analyzed, and the approach to solve this problem was presented. In the course of obtaining the parameters of thunderstorm with the electric field, the problem in the arithmetic was discovered, and suggestions to solve it were given.
