环境温湿度模糊识别传感系统设计与仿真分析

Design and simulation analysis of fuzzy identification sensor system for environment temperature and humidity

针对现有温湿度传感器存在的缺点和不足,根据模糊测量原理,设计了以"人体舒适度"为输出对象的智能温湿度传感器系统,该系统融入了专家系统,综合考虑了环境温度、湿度和季节等相关因素对人体舒适度的共同影响。在MATLAB条件下建立仿真模型,对该系统进行了仿真测试,仿真结果表明,该系统能够根据推理规则很好的输出"人体舒适度"的模糊语言值,比传统单一数值式传感器的测量更加智能化和人性化。本设计可在一定程度上弥补传统温湿度传感器只能输出固定值,不具有判断能力的缺陷。

Aiming at the shortcomings and deficiencies of the existing temperature and humidity sensor,according to the principle of fuzzy measurement,an intelligent temperature and humidity sensor system is designed, which takes ＂human comfort＂ as the output object. The system is integrated into the expert system. The combined effects of environmental temperature, humidity, season and other factors on the comfort of human body were considered.Simulation model is established under the condition of MATLAB,the results show：the system can output the fuzzy linguistic value of ＂human comfort＂ according to the rules of reasoning, which is more intelligent and humane than the traditional single numerical sensor.The design can make up for the defect which is the traditional temperature and humidity sensor can only output fixed value,not have the ability to judge.
