摘　　要：针对传统电力基坑气体较多且不易分辨,也比较容易出现基坑内工作者的中毒问题,设计一种多气体检测系统。系统采用光声光谱检测及声光报警电路和蜂鸣器报警电路的方法,能够实现基坑内有毒气体的的检测。系统在硬件结构上可以划分为电源模块和处理器、数模转换模块、气体传感器模块,通过这3个模块的配合,能够实现基坑内多种气体的识别工作。实验结果表明,所设计系统在检测误差较小,测量精度更高。In view of the fact that there are many gases in the traditional electric power foundation pits and it is difficult to be distinguished,and the problem that workers in the foundation pits are more likely to be poisoned,a multi-gas detection system is designed.The system adopts the method of photoacoustic spectrum detection,sound and light alarm circuit and buzzer alarm circuit,which can realize the detection of toxic gas in the foundation pits.The system can be divided into power supply module and processor,digital-to-analog conversion module,and gas sensor module in terms of hardware structure.Through the cooperation of these three modules,it can realize the identification of various gases in the foundation pit.The experimental results show that the designed system has smaller detection error and higher measurement accuracy.
