基于LabVIEW的环境空气质量监测系统

摘要

针对提高环境空气质量的实时性监测进行设计,并利用虚拟仅器技术减少硬件设计;虚拟仪器开发平台LabVIEW用以实时监测、显示采集曲线和数据;无线传输模块用以解决空间局限性问题,运用曲线拟合技术实现传感器误差修正和误差曲线分析,提高系统采样精度,同时对响应时间和采样精度进行实验观察;系统改变传统监测方法,实现监测系统模块化,智能化、系统化和实时化.%The design of real-time monitoring system of air quality is disccussed. The use of virtual instruments can reduce hardware designs. The real-time monitor, the display of curve and data are based on virtual instrument development platform LabVIEW. The use of wireless transceiver can get rid of space limitation and physical wiring, and curve fitting technology is used to achieve error correction and analysis, improve accuracy of the systematic sampling. This system has changed the tranditional methods, made the decetion system modular,intelligent, systematic and real time.
