基坑有毒有害气体便携式智能监测报警系统设计

Design of Portable Intelligent Monitoring and Alarm System for Toxic and Harmful Gas in Foundation Pit

为保证基坑工程施工人员的人身安全,需要提升有毒有害气体智能监测范围和预警效果。为此,本文设计一种有毒有害气体便携式智能监测报警系统。首先进行气体检测设备选型,再优化网络接口以及中央控制器。使用最优滤波法,构建有毒气体信号滤波分析模块,再提升监测预警模块性能。最后经系统测试可知,设计系统的监测范围与预警效果均较优,可以为保证基坑工程施工人员人身安全提供一定帮助。

In order to ensure the personal safety of foundation pit construction personnel,it is necessary to improve the intelligent monitoring range and early warning effect of toxic and harmful gases.Therefore,this paper designs a portable intelligent monitoring and alarm system for toxic and harmful gases.Firstly,it selects the gas detection equipment,and then optimizes the network interface and central controller.Using the optimal filtering method,the toxic gas signal filtering analysis module is constructed,and then the performance of the monitoring and early warning module is improved.Finally,the system test shows that the monitoring range and early warning effect of the designed system are excellent,which can provide some help to ensure the personal safety of foundation pit construction workers.
