摘要： 介绍了某型飞机调控装置的组成及工作原理，针对该调控装置在投入正常工作之前无自检功能的弊端，着重论述了利用MCS-51单片机对该装置实现自检功能的硬件电路设计及软件设计。考虑对该装置加装自检功能后，用户需在发动机不开车而发电机不发电的情况下对其实施自检，因此文章阐述了供该系统使用的模拟飞机发电机和永磁机产生的各种交流电模拟电源电路设计。

Abstract: Based on the components and principle of plane regulating device, this paper discusses the hardware circuit design and software design for self-testing system by using of MCS-51 single chip microcomputer because the regulating device has no function of self-testing before working in order. For the self-testing needs to be done in the case of no working of both engine and generator, this paper discusses the design of analog power circuit that is used for this self-testing system. This circuit imitates all kinds of AC generated by plane engine and permanent magnet generator in fact.
