基于Socket通信的GPS校时软件研发及应用

Development and Application of GPS Time Calibration Software Based on Socket

为了便于统一管理智能电能表检定计算机日期与时间,研发出一套基于Socket通信的GPS校时软件,软件采用C/S运行模式,服务器通过GPS卫星定位系统接收器获取标准时钟,客户端以主动校时或自动校时方式与服务器时间保持一致。应用期间,客户端计算机时钟与服务器基准时间误差保持在5s范围内,方便了电能表检定工作。

A GPS time calibration software based on Socket was developed for the united management of the time clock of the intelligent energy meter calibration computer. The software uses C/S mode, in which the server gets standard time clock from a satellite by GPS and the client keeps pace with the server by active time calibration and automatic time calibration. In practical application reference time difference between the server and the client is kept within 5s, convenient for energy meter calibration.
