基于FPGA的井下多参数检测仪的设计

DESIGN OF MULTI- PARAMETER DETECTOR IN COAL MINE BASED ON FPGA

本文介绍一种以FPGA为核心控制处理器的对CH_4、CO、H_2S和O_2气体浓度以及环境温度、湿度等6个参数进行检测的井下多参数检测仪,依靠多种气体传感器做成的传感器模块精确检测井下气体的含量,将气体含量等参数通过LCD显示屏进行显示。实验结果表明,这种多参数检测仪具有集成度高、智能化、低功耗等优点,能够对井下气体浓度信号进行高速精确处理,软、硬件设计稳定可靠,达到设计要求。

This paper This system mainly detects the gas concentration of CH4,CO,H2S and O2 and the environment temperature humidity and so on six parameters. And FPGA was based on as the main processor,with many kinds of gas sensors together to accurately detect underground gas,then the datas of gas content display through the LCD screen. Experimental results show that the multi parameter detecting instrument has advantages of high integration,intelligent,low power consumption. It meets the high speed of underground gas concentration signal processing accurately,Thesoftware and hardware design is stable and reliable,meet the design requirements.
