基于STM32的GPS授时系统设计

Design of GPS Timing System Based on STM32

本文设计了一种基于STM32高速单片机的GPS卫星授时时钟,它由四部分组成,分别是接收机、中央处理单元、LCD显示和输出接口。其中接收机用于接收标准时间信号,中央处理单元的作用是处理数据,可同步输出时间数据,保证高精度授时。这不仅能解决时间获取问题,而且能真正实现全球范围内的时间校准。该方法不仅具有实现手段简单、精度高、范围大等特点,还具有无需通道联系,不受地理和气候条件限制等优势,是理想的时钟同步方法。本文介绍了基于STM32的GPS授时时钟装置的硬件;根据装置要实现的功能,给出了主程序和中断程序的流程图和程序介绍。

This paper designed a GPS satellite timing clock based on STM32 high speed microprocessor,which is composed of four parts：receiver,CPU,LCD display and output interface.The receiver is used to receive standard time signal,and the CPU is used for data processing,which can output time data synchronously,thus ensuring high precision timing.This can not only solve the problems of time acquisition,but can truly realize global time calibration.This method has features of simple implementation means,high precision and large scope and there is no need of channel contact.It is free from the restriction of geographical and climate conditions.So it is the optimal clock synchronization method.This paper introduces the hardware of the GPS timing clock device based on STM32 and the supposed function.The main program and interrupt program flow chart and program introduction are presented.
