摘要
GPRS通信技术不需要架设通讯线路,组网灵活方便,是解决配网自动化系统通信问题的有效手段。但是该方案在整个配网系统中增加了无线传输和数据中转等环节。为保证数据传输过程的安全,采用PKI技术为系统参与通信的前置设备和远程服务器发放数字证书,实现安全通信。
It is an effective method to solve the problem of communication in distribution network automation system by GPRS, because communication via GPRS doesn＇t need to set up the communication line and can make net- works more freely and expediently. In order to ensure date safely when transferring via GPRS, PKI is used for issuing a digital certificate to communication nodes that are preceding device and remote server.
