某导弹模拟训练系统研究

某导弹模拟训练系统由模拟训练操作平台、控制计算机(内含数据采集卡PCL-733)、视景显示计算机等组成．操作平台的操作输出为模拟电压信号，控制机通过I／O地址采入数采卡上数据并处理后，用RS-232与视景机串行通信，适时发送控制和音像播放指令．由于图像与模拟对象在两台计算机显示，故采用Mscomm32．ocx串行通信控件(Mscomm)完成数据的读入与输出．视景机根据图像帧数与模拟对象位置的相对关系，适时返回模拟对象的状态信息以实现视景同步．

Research on Simulation Training System for Missile

Simulation training system for missile is mainly comprised of a simulation operating platform, a control computer (with a data access card PCL-733 inside) and a scenery-view computer. The control computer accesses data of data acquisition card via I/O and deals with data, and communicates with scenery-view computer by RS-232, sends out control and media play commands timely. Because the scenery and the simulation object displays on different computers, data input and output is realized by serial communication control Mscomm. The scenery-view computer returns the state message of simulation object timely according as the corresponding relationship between media frames and the position of the object, and so scenery-view synchronization is realized.
