温度测试技术应用广泛,爆轰过程的现场温度测试环境比较恶劣,常伴有高压或高速气流流动,多为不可重复一次性过程。为了提高测试系统准确性,提出了一种基于FPGA和无线通信的温度采集系统的设计。本文结合瞬态测温技术发展现状,具体阐述了该系统总体方案的设计思路以及关键技术,同时分析了采用FPGA、无线通信、光纤模块带来的高效性、低误触发率、灵活的远程控制等优点,该系统经过多次靶场实爆实验,实验结果表明该系统具有较高的灵活性、可靠性和稳定性。
The temperature testing technology is widely used. The on-site temperature testing environment of the detonation process is rather harsh, often accompanied by high-pressure or high-speed airflow, mostly nonrepeatable disposable processes. In order to improve the accuracy of the test system, a temperature acquisition system based on FPGA and wireless communication is proposed. In this paper, the development of transient temperature measurement technology is introduced, and the design scheme and key technologies of the overall scheme of the system are expounded in detail. At the same time, the high efficiency, low false trigger rate, flexible remote control using FPGA, wireless communication and fiber module are analyzed. And so on. The system has undergone multiple explosion tests at the shooting range. Experimental results show that the system has high flexibility, reliability and stability.
