运载火箭桌面联试系统串口通信实现方法

The Method of Realizing Serial Communications of the United Testing System on Desktop of Carrier Rocket

运载火箭桌面联试系统主要利用微机的RS-232口进行串行通信,主控计算机与发控台、箭机之间多路串口通信的实现方法在运载火箭测试发控系统设计中占据重要地位.介绍了Windows环境下用VC++语言实现串口通信的基本方法;指出了利用ActiveX控件MSComm和Windows API函数进行串行通信的主要步骤及注意事项;阐述了联试系统串口通信的结构设计、硬件配置及其编程要点,对串口通信的学习和使用者具有一定的借鉴作用.

Serial communications of united testing system on desktop of carrier rocket is mainly realized through computer's RS232 port. The method of realizing multiserial communications between main control computer and launching console, rocket computer plays an important role in the design of the testing and launching system of carrier rocket. The basic method of realizing serial communications with VC++ program language under the environment of windows is presented in this paper. The main process and noticeable points of the program of realizing serial communications with an ActiveX control MSComm and Windows API function are pointed. And structure design, hardware configuration as well as corresponding program points of serial communications of the united testing system are also expatiated, which would supply some conference for the people studying and using serial communications.
