摘　　要：介绍了一种基于AT89S52单片机的陆标定位模拟器系统的设计,主要内容为单片机外围电路设计。为了改善系统通信的可靠性,定义了一种串口通讯协议;为了提高直线插补的精度,对常规的直线插补算法进行了改进。实际应用验证了系统的可行性。This paper introduces a simulator system for terrestrial fix based on At89S52 chip microcontrollers, including the periphery circuit. The host computer uses serial port while the slave computer uses the AT89S52 in order to improve communication reliability and to realize the self-defined protocol of serial communication. An improvement on new interpolating recurrence algorithm has not only a clear meaning and simple arithmetic, but also high accuracy. The feasibility of the system is proved.

关 键 词：单片机 串口通讯 直线插补
