摘要
以W78E58和XCS10为核心,以高精度石英晶体为频率标准,以GPS所提供的日期、时间为时间标准,并配以TMP82C79按键模块和LG12864液晶显示模块,设计和实现了高精度多功能时间校验仪系统.该系统可以测试复费率和多功能电能表的计时基准频率和时段投切误差,并给被校表授时.
In this paper,on the basis of the W78E58 and XCS10,combining the TMP82C79 keying model and the LG12864 liquid crystal display model,the system of high-precisi on multi-function time calibrator is designed and implemented,and it a dopts the high-precision quartz crystal as frequency standard,and the date and tim e provided by GPS as time standard.This system can test multi-rate and the tim ing reference frequency and switching period error of the multi-function electr icity meter.
