摘要
本文针对中国制式(BPC)低频电波授时技术保密,难以深入研究的问题,提出基于51单片机的日本制式(JJY)低频电波授时接收机,给出该系统的原理、设计、实现和验证过程。该系统能以低廉的成本获取高精度的标准授时信号,具有实现简单,技术公开的优点,对提高中国的低频授时技术有一定的参考意义。本文提出的系统能够实现"秒"的严格同步。
The paper investigates digital low frequency receiver with Japan’s format JJY based on MCU of 51 series,according to the difficulty that it’s hard to investigate China’s time service technology with format BPC.The principle,design,realization and verification are presented in this paper.The system which gets standard and high accuracy time service signals with low cost is easily realized and the technology is disclosed.The system presented in this paper realizes synchronization on the basis of second.
