带微处理器的自动校时数字钟

Self-Calibrating Digital Clock with Microprocessor

本文就目前地震台站普遍使用的小规模CMOS电路构成的数字钟元件多、可靠性不高等缺点,提出以INTEL 51系列单片机为核心构成的具有自动校对功能的数字钟,本系统硬件结构简单,系统可靠性强,并可自动根据BMP信号校时,操作简便且精度高。

In allusion to the defect of the digital clock using small scale CMOS integrated circuit, a self - Calibrating digital clock bused on INTEL51 single chip microprocessor is presented. This system is simple, high reliable, easy to operate and high precise, and can be automatically calibrated according to BMP signal.
