多通道直升机加载系统的协调问题研究

Multi-Channel Harmony Technology Used in a Helicopter Airscrew Loading Test

针对直升机旋翼加载系统,提出了多计算机分布控制系统结构,研究了这种结构的多通道协调问题和解决办法。实际系统运行结果表明,该系统具有结构简单、开放性好、信号相位协调精度高等优点。

A design of a distributed computer control system which is used in an armed helicopter airscrew multi-channel harmony loading test is discussed.The construct of the hardware and software of the system is introduced.The technical essentials of the harmony loading system, such as multi-channel signal synchronization,signal phase modulating and frequency excursion control are discussed.The results of test show that it has characteristics as follow:easy constructed and operating,expandable,high precision of signal synchronization and phase harmony.
