摘要
文章介绍了一种机载设备的通讯接口电路的设计与实现,该接口电路是机载设备接线盒的重要组成部分,其设计目标主要是接收前端的综合处理机通过422接口输出的目标方位、目标距离、目标编号、目标有效等命令信息,对其进行格式转换和电气匹配后,再送到发控系统。此外,该通讯接口电路还对接收到的干缆高度数字信号进行数模转换等相关处理,并发送到飞机控制系统和悬停器。
The design and implementation of a communication interface circuit in airborne equipment is introduced, which is an important part of the interface box in airborne equipment. The circuit receives the command information output by 422 interface of the integrated processor, such as target bearing, target distance, target designation, and target effective, and sends it to the fire control system after format conversion and electrical match. Moreover, the circuit will make D/C conversion etc. for cable height digital signal, send it to aircraft＇s control system and hover device.
