基于FPGA+ARM+WIFI的炸药冲击波超压采集系统设计

Design of Explosive Acquisition System for Shock Wave Overpressure Based on FPGA + ARM + WIFI

针对冲击波超压测试中的通用测试系统布设繁杂、存储测试系统状态无法监测和难以远程控制等问题,设计了基于FPGA、ARM和WIFI的冲击波超压采集系统,实现了对测试装置远程控制和系统工作状态的监测,省去了繁琐的布线。测试数据通过无线WIFI传送到上位机进行处理、显示。为了防止数据丢失,设计了USB接口用于数据的有线读取。多次靶场实爆试验表明:系统稳定、无线通信可靠;给出了某当量炸药的冲击波超压曲线。

To solve the problem sincluding complicated wiring of universal test system,unable monitoring to the stored testing system and difficult remote control in the shock wave overpressure measurement,a new overpressure measurement system was designed based on the technologies of FPGA,ARM and WIFI. It has the function of controlling the test sets remotely,monitoring the system state and eliminating the cumbersome wirings. Data is transferred to the PC for processing and displaying by WIFI. To prevent data loss,it also designed the USB interface to read the data. In the several real explosion experiments of shooting range,the results show that： the system is stable and the wireless data transmission is reliable. The shock wave overpressure curves for a certain explosive were also given out.
