Abstract

A multi-processers monitoring and control system, which use the Lora as wireless communication technology, was designed to meet needs of mobility, safety, fast frequency adjustment, portability, none affect on PDE thrust test and so on. This paper elaborated on scheme of whole system, local high-speed signal acquisition, storage, data export and ignition control method. Experimental results show that the monitoring and control system was able to implement timely and accurately control and data acquisition of detonation tubes, dynamical parameters changing, remote control and eliminate the damage for human beings caused by PDE, with mobile and portable, high integration, convenient operation, reliable performance characteristics.

摘要

根据多管点火脉冲爆震发动机工作原理及实际工作中对移动性、安全性、快速频率调节、便携性、消除控制器对发动机推力测试影响等方面的要求，设计出基于Lora无线通讯的多处理器脉冲爆震测控系统。详细阐述了测控系统整体方案，本地高速信号采集、存储及数据导出及点火控制方案。长期试车表明，该测控系统能够实时精准进行8管脉冲爆震发动机的协调控制，动态调节工作参数，高速实时采集爆震管信息，试车时操作人员在观察室远程操作，消除PDE工作过程中产生的爆炸强声对人体造成的伤害，具有移动便携、集成度高、操作方便、稳定可靠等特点。
