基于ARM的冲击波测试系统的便携终端设计

Design of a Portable Terminal Based on ARM for the Test System of Shock Wave Pressure

在冲击波测试中,测试系统的状态难以监测,测试参数一旦设置不当便无法现场更改;而以PC为系统的控制终端,在户外试验时存在操作不便、不易携带的缺点。针对以上问题,设计了基于ARM的便携控制终端。利用Qt技术设计了图形控制界面,对无线通信进行了性能测试。手持终端通过无线控制测试系统,实现了对测试系统状态的监测、数据的无线传输与波形显示。将手持终端应用于弹药试验,结果表明,其具有良好的可靠性和稳定性。

In the measurement of shock wave overpressure,the status of test system is hard to be monitored,and test parameters could not be adjusted on site once they are improperly set up. Meanwhile,it is inconvenient to operate and hard to carry the traditional PC in outdoor experiments. In order to solve such problems,a portable control terminal for shock wave pressure test system based on ARM was designed. The graphic application program was developed by the software of Qt. Performance test in the actual explosion environment was used to verify the reliability and stability of wireless communication. The functions of system state monitoring,data transmittal by wireless and waveform display could be realized by the portable terminal with wireless test system. Results show that the portable terminal has good stability and reliability in real explosion experiments.
