提出了某武器系统一种射击训练模拟器系统结构,设计了射击训练模拟器信号采集和通信专用接口,并利用C++Builder 平台采用通信控件MSCOMM 编写了上位机通信程序,利用C 语言编写了下位机通信程序。通过RS232 总线实现了单片机与PC 机的通信。实现了某武器系统训练模拟器操作手训练过程信号的采集和通信。 关键词:训练模拟器;MSCOMM 控件;串行通信;专用接口。 Absrract: This paper presented a kind of certain weapon system to train simulator construction of system .The signal collection and communication interface for special purpose was designed.. In C + + Builder platform ,with communication control MSCOMM ,the communication program between personal computer and single chip was compiled. Through RS232 bus line, the communication of single chip and personal computer were realized. At the same time , certain weapon system to train simulator operating hand the course of communication and the collection of signal were realized. Keywords: Training simulator; MSCOMM controls; serial communication; signal interface
