基于LabVIEW的机电管理电源监测系统设计

针对某型机机电管理系统电源参数全过程综合监测分析能力弱、故障判断余度少等问题,设计了一种新型机电管理电源监测系统。利用工控计算机上的串行通讯板卡通过RS422A总线与机电管理计算机进行硬件联接,基于LabVIEW软件开发了监测程序界面。程序设计中,采用生产者-消费者循环架构进行数据的采集与处理,解决了大量数据传输的丢包问题；利用按钮事件将电源参数的监测数据发送到波形控件进行全过程显示分析；故障判断利用故障状态数据及波形数据综合判断,提高了故障监测的可靠性。通过实验测试,电源监测系统能够有效地完成参数全过程监测分析、能够准确可靠地进行故障判断。

Electromechanical Management Source Monitoring System Based on LabVIEW

Aiming at the problems of the weak whole process comprehensive monitoring-analyzing ability and the low fault diagnosis redundancy in the electromechanical management source monitoring system of a certain type of aircraft, a new electromechanical management source monitoring system is designed. The system uses a serial communication board on the industrial computer to connect hardware with an electromechanical management computer through the RS422A bus, the monitoring program interface is developed based on LabVIEW software. In the program design, the producer-consumer cycle architecture is used to collect and deal with data, and the problem of data packet loss is solved, the button event is used to send monitoring data of source parameters to waveform for whole process of display and analysis, fault diagnosis makes use of fault state data and waveform data synthetically to improve reliability of the fault monitoring. Through the experimental test, the power monitoring system can effectively complete the whole process parameters monitoring and analyzing, and can make the fault diagnosis accurately and reliably.
