【摘要】 介绍了一种以DSP芯片为基础的定北仪远程监控系统的设计与实现。鉴于RS422接口以差动方式传输，具有传输距离长、抗干扰能力强的特点，该监控系统以RS422接口实现TMS320C32与PC机之间的远程通信，从而使PC机能在几百米之外对定北仪进行实时监控。更多还原

【Abstract】 The design of a monitoring system based on the communication of DSP and PC is introduced in this paper. Since the RS422 standard transfers data in differential way, data communication can be implemented at a long distance. The monitoring system based on RS422 makes PC monitor and controls the northfinder working hundreds of meters away.更多还原
