基于模糊评价算法的环境检测系统的设计研究

人们工作与生活的环境越来越多的受到社会关注,面向室内工作场所,建立一种针对室内环境空气等级的评价方法具有重要的实践价值.采用ARM嵌入式硬件平台,linux操作系统,利用多种传感器对环境数据进行采集,以温度、湿度、甲醛含量、CO2浓度以及粉尘含量做为评价因素,根据五种参数的权重和耦合关系,对环境进行综合评定.系统具有实时数据采集、数据分析、数据显示、评价因子增添和删除、自定义评价范围和评价结果显示等功能.模糊综合评价理论兼顾了主观与客观的事实,对于不同环境具有相对灵活性.

Design of Environment Detection System Based on Fuzzy Evaluation Algorithm

People are becoming more and more concerned with environment,in which live and work. It is of great practical value to establish an evaluation method for indoor air grade of enclosed workplace. Based on ARM embedded hardware platform and Linux operating system,through the environmental data which are collected by various sensors,this paper conducts the com-prehensive assessment for the environment in accordance with the weight and the coupling relationships of five parameters of tem-perature,humidity,formaldehyde content,concentration of CO2,and dust content. This system has the functions of real-time data acquisition,data analysis,the addition and deletion of evaluation factor and self-defining evaluation scope,etc. Fuzzy com-prehensive evaluation theory takes into account the fact of subjective and objective and it has relative flexibility for different envi-ronments.
