摘　　要：以平台罗经故障检测系统作为项目背景,分析了多串口通信的作用和设计思想.综合串口设备的特点,提出一套相应的串行通信软件设计方案,包括难点解决及定义了通信定时协议,并给出了相应的设计流程.实际运行表明,该方法实现简单,功能适用,运行可靠.This paper is mainly dealt with the study of reliability of multiple serial-ports communications. The functions and principles of multiple serial-port communications were analyzed with the fault detection system of a stabilized gyrocompass as an example. Following the analysis of different devices of multiple serial-port units, a software design scheme for serial-port communication was presented, including the solution of some key technologies and the communication timing protocol. The design flow-chart was given. The actual operations of the system showed that the system is simple to realize, suitable in function and reliable in operation.
