飞机轮胎压力监测系统的设计

Design of Aircraft Tire Pressure Monitoring System

飞机在跑道上降落瞬间由于受到较大冲击可能爆胎;针对这一问题,研究了飞机轮胎压力监测系统;首先叙述了系统的研究背景与现状,系统方案的选择以及所选方案的技术问题及解决办法,具体分析了各部分电路工作原理,进行了相应的理论分析及参数计算,给出了各部分的硬件设计原理图、实物图以及软件流程图,并进行了实验验证;实验结果表明,该系统可以对轮胎压力进行精确测量和控制,从而可以有效避免飞机降落爆胎事故的发生,提高飞机安全性。

At the moment of landing, the tires of the aircraft will possibly explode. In view of this problem, a general framework refering to the aircraft tire pressure monitoring system is introduced. Firstly, the development foreground and actuality about ATPMS and the selection of system schema as well as technical problems and solution has been depicted in this paper. Combining the theoretical analysis and parameter count, the principles of every part circuits are analyzed in detail. Then system schematic circuit diagrams, practical pictures, program flow charts and the experimental verifications are presented. Experiment result indicates that the pressure of tires can be controlled accurately, thus the landing explode accident can be avoided; the safety of the aircraft is enhanced.
