基于DLPTP时钟同步机制的电力用电信息采集系统对时方法研究
Research based on the time clock synchronization mechanism DLPTP power information collection system
The electric information acquisition system master station, data acquisition terminal, electric energy meter clock accuracy for power, this custom transmission protocol of power system based on DLPTP protocol, using GPS first calibrate the master of time, and then to the main station for reference, using DLPTP protocol by time of acquisition terminal, the final adjustment of electric energy meter the clock of the equipment, and gradually realize the synchronization of the system clock, so as to guarantee the consistency of all equipment clock system, effectively improve the accuracy of data acquisition system.
