摘要
本文介绍了一个宽量程、高精度的火光爆炸闪光强度测试系统。本系统是采用ATMEGA128单片机作为中央处理器,高灵敏度光电倍增管作为测光探头,高精度放大器OPA4132作为信号调理电路,高速A/D转换芯片MAX1304作为数据采集模块,高速USB芯片CY7C68013A作为通信传输模块,以及采用基于VC++的虚拟仪器LabVIEW作为人机操作界面。通过本系统将能把闪光强度数据实时的在PC机上显示出来。
This article describes a wide range, high-precision flash strength testing system.The system uses the ATMEGA128 as a processor,and uses a high--sensitivity silicon photodiode as the metering probe. This system realizes real--time data acquisition and high--speed high-precision signal processing and transmission.This system fully reflects the modular design concept,the use of efficient data transfer protocol and virtual instrument design can achieve high reliability,and real-time display the flash intensity curve.
