作战指挥自动化系统用电子瞄准镜的设计

The Design of Electronic Collimation device for Automated Command System

电子瞄准镜是单兵导弹雷达指挥系统的一部分。雷达系统对空搜索,发现和跟踪目标,并将目标的方位、高低等信息通过串口传给电子瞄准镜系统。电子瞄准镜系统由单片机W77E58,电子罗盘TCM-20,通信接口,EL显示屏组成。单片机作为中央控制器完成和雷达的串口通信,获取目标信息。电子罗盘获取发射筒当前所指向的方位,显示屏显示目标的方位、距离、航迹和射击筒方位信息。单片机与电子罗盘采用RS232通信、与雷达系统的计算机采用RS422通信,显示屏的驱动和显示是对SED1335的写操作。同时,给出了单片机的软件工作流程。

The electronic collimation device is a part of radar command system. The radar searches and tracks the objects. As the same time, the azimuth and height information of the object will be sent to electronic collimation system through UART. The electronic collimation system is made of microcomputer W77E58, electronic compass TCM-20, communication interface and EL display. The microcomputer is the command center, it get object information from radar through UART. Electronic compass get the azimuth information of electropult, and the azimuth, distance and track of object will be displayed on EL display. The microcomputer communicates with the compass through RS232, it communicates with radar through RS422. The display and driving of EL display is a writing operation of SED1335. The software flow of microcomputer was given in this paper.
