基于μC/OS-III的喷雾结冰控制系统的设计

Icing spray control system based on μC/OS-III

摘要:

结冰是影响飞机安全飞行的重要因素,在某一型号飞机投入使用前,需要对该飞机除/防冰系统的性能进行验证。因此,研制了一套基于μC/OS-III的机载喷雾结冰控制系统；给出了系统的整体结构框架及其组成,重点介绍了该控制系统的硬件及软件的设计思路；系统实现了对喷雾设备的水、气路温度及压力的自动调节,在此基础上,还具有参数监测与显示、系统报警、数据分析与保存等功能。试验结果表明,该控制系统具有运行稳定、实时性好、调节速度快、控制精度高等特点,可以使用该系统进行喷雾结冰试验来考察某机型除/防冰系统的工作性能。

Abstract:

Icing is an important factor affecting the safety of aircraft flying, before a kind of aircraft putted into use, the performance of the aircraft’s anti-icing system needs to be verified. Therefore , a set of airborne icing spray control system based on μC/OS-III is presented. This kind of system is able to control spray device’s water and gas’s temperature and pressure automatically , moreover, the system has a display parameter monitoring, alarm systems, and data analysis and saving. Flight tests show that the system has advantages of high reliability, real time , adjust quickly ,control precisely, so can be used to test the performance of the aircraft’s deicing/anti-icing system.
