摘要
针对在地震等自然灾害及遮蔽空间范围传感器体积受限制和对周围环境参数感知问题,设计了三维微组装多气体传感器测试仪,结合设计的GPSO-BP算法,该测试仪可以在高温高湿的环境下实现实时对有毒气体浓度以及压力的多参数测量,并对其进行温湿度补偿,具有高性能、小型化、准确度高的特点。测试结果表明,在湿度为80%RH,温度为50℃的环境下测量不同气体,经过温湿度补偿后,该测试仪的准确对度至少提高到2.2%以上,稳定性较强,对于地震等恶劣环境下的环境参数感知具有重大的意义。
In this paper in the natural disasters such as earthquakes and shelter space range sensor volume restricted and parameters on the surrounding environment perception problem,a gas sensor for a three-dimensional micro assembly tester,combining with the design of GPSO-BP algorithm,the tester can realize real time under high temperature and high humidity environment to the concentration of toxic gases and pressure of multi-parameter measurement,and the temperature and humidity compensation,with high performance,miniaturization,high accuracy characteristics.The test results show that in the humidity of 80%RH,temperature of 50℃environment measurement of different gases,after the temperature and humidity compensation,the accuracy of the tester is improved to at least 2.2%above,strong stability,for earthquake and other harsh environment of environmental parameters perception is of great significance.
