Research and Application of Dual Redundant Engine Condition Monitoring Technology

摘要:

在飞机、舰艇、装甲、汽车电子控制系统中采用双余度发动机状态监测技术,能够有效提高飞机、舰艇、装甲、汽车运行的安全性和可靠性,以某型涡轴发动机为研究对象,对双余度发动机状态监测技术进行了深入研究,研制了双余度发动机状态监测系统,介绍了系统的总体设计、软硬件设计、余度设计,虚拟仪表设计,并在双余度发动机状态监测系统的设计中引入了嵌入式PC/104模块；为了使状态监测系统具有更好的扩展性和适应性,将系统设计成可以在两种方式下工作:机载运行方式和地面试车方式,通过这两种方式对发动机状态进行自动监测,为发动机的状态趋势分析、故障诊断和视情维修提供科学的依据；采用双余度发动机状态监测技术研制的某型涡轴发动机状态实时监测系统经过了大量的地面试验和某型直升机上试飞试验,功能、性能满足要求,目前该系统已在某型直升机上得到应用。

Abstract:

The application of dual redundancy engine condition monitoring technology in aircraft, ships, armored , automotive electronic control system can improve the security and reliability of aircraft, ships, armored, auto running. A turbo shaft engine as the research object,the dual redundancy engine condition monitoring technologies are studied, we develop a dual redundancy engine condition monitoring system,this paper introduces the overall design, hardware and software design of the system, redundancy design, the design of virtual instrument, and introduces the embedded PC/104 module in the design of dual redundant engine condition monitoring system. In order to make the scalability and adaptability of the condition monitoring system has better, this system is designed to work in two ways:airborne operation and ground test method. Automatic monitoring the state of the engine by the two way, to provide scientific basis for analysis of status, trend of engine fault diagnosis and condition based repair.The turbo shaft engine condition monitoring system using dual redundancy engine condition monitoring technology has got acorss extensive ground tests and flight tests in a certain type of helicopter,it can fulfil the requirements of function and has a good performance.At present, the system has been applied in a certain type of helicopter.
