摘要
分析了原有的大气数据实验系统的不足,设计了基于ARM单片机和闭环压力控制的新型实验系统。给出了新型实验系统的组成方案,详细介绍了实验系统硬件设计和软件设计方法。新型实验系统具有体积小、集成度高、压力测量的准确度高、能够实现对压力的精密控制等优点。测试结果表明,新型实验系统有助于学生们更好地理解飞行大气参数计算原理,适合课程实际需要,具有航空航天特色。
We analyze shortcomings of quondam air data experimental system. A new air data experimental system which is based on ARM microcontroller and closed-loop pressure control is designed. A composition scheme of the new experimental system is put forward. We also introduce the methods of structural design and software design of the experimental system in detail. The new experimental system has advantages of small size, high integration, high accuracy of pressure measurement, and precise control of pressure. The experimental result indicates that the new system can help students more easily understand the calculation principle of flight atmospheric parameters. This system is suitable for the demand of this subject and has the characteristic of aerospace.
