基于PC/104的某飞机任务电源监控系统设计与实现

Design and Implementation of Supervisory and Control System for Aircraft Secondary Power Based on PC/104

某飞机任务电源系统需要监控系统以保障飞行任务的供电安全。为提高其监控系统的可靠性和可维护性,完成了基于PC/104和远程数据采集模块的某飞机电源监控系统的设计与实现。该系统运用结合RS-485进行多串口通信,将采集的数据返回给监控界面,实现对远程终端的监控,以图形化编程软件LabVIEW为平台完成了采集与监控各部分的软件设计,并通过了各项测试,具有很好的稳定性和安全性,实现了对电源系统的监控、报警和保护。

A certain aircraft secondary power needs a supervisory and control system to ensure the safety of power supply.In order to improve the reliability and maintenance of the supervisory and control system,a kind of supervisory and control method for a certain aircraft secondary power with modularization based on PC/104 and long-distance data acquisition is designed and implemented.This method can realize multi-serial port communication by combining with RS-485.It sends the data collected to supervisory control interface and realize the supervisory and control of long-distance user.The design of the acquisition and supervisory software is completed on LabVIEW plat,and the system is tested in several environment.It can accomplish the functions of supervisory,alarming,and protection.
