液体火箭发动机多Agent故障诊断技术研究

Study of fault diagnosis system for liquid rocket engine using multi-Agent

利用多Agent技术建立了液体火箭发动机故障检测与诊断系统,包括小波去噪、传感器检测、故障检测、故障诊断和系统总调度等功能.利用多线程编程、动态链接库及网络编程技术,使故障检测与诊断系统具有较高的智能性.给出了小波去噪、传感器检测等Agent的运行算例,并给出了故障检测与诊断系统的整体框架.

This paper established fault detection and diagnostic system of liquid rocket engine based on multi-Agent technology, which included wavelet denoising, sensor detection, fault detection, fault diagnosis and main scheduler program. Using multithread programs, Dynamic Link Library and network programming technology, the fault detection and diagnostic had better intelligence. This paper illustrated several Agent examples of wavelet denoising and sensor detection, and demonstrated the framework of the fault detection and diagnostic system.
