Research And Implementation Of Regional Environment Wireless Monitoring System

The condition of human environment greatly affects the health of human beings, espe-cially in sealed and semi-sealed space, it should pay more attention.If conditons of the re-gional environment can not achieve the good conditin, it causes some potential trouble topeople’s health, which is reflected in all aspects of environment parameters, such as tempera-ture, humidity, light intensity and concentration of unhealthy gases in the environment.Now, many regional environmental monitoring equipments can transmit parameter databy using wired systerm. But in the process of monitoring environmental parameters, it willnot only bring wiring problem, but also influence the protabilityy and the the portability ofthe system. In view of this, it designs the regional environmental monitoring systemof real-time and wireless transmission data.The wireless monitoring system has perfectreal-time, mobility, and flexibility than the wired monitoring system.Temperature,humidity,light intensity and carbon dioxide are determined the importantparameters than others through the comprehensive analysis of the region’s environ-ment.According to the data form and characteristics,the hardware is composition of wirelessdata radio based on radio frequency integrated circuit and sensor acquisition module based onSTC12SCM.The design of hardware strictly regulates,little interference and perfect overallsystem performance.The part of software is based on MFC single document application toanalysis and forecast the future datqa through MATLAB. The design of hardware and soft-ware uses modular. The part of hardware can collect and send data through wireless commu-nication module and acquisition module.Then another wireless communication module canreceive the data.The Received data sends the computer through the wireless communicationmodule. It achieves monitoring data real-time displaying, storing, alarming and describingcurve through the MFC visual interface.Finally, it analyses and predicts data using BP neural network.The regional environmental wireless monitoring system has the characteristic oflow-cost, low-power, perfect versatility and strong flexibility and so on.The wireless commu-nication protocol has the charaterist of license-free.And it also can achieve the teal-time andeffectiving monitoring of environgment parameters.After the appropriate extension and de-bugging,it can easily be applied to others monitoring areas.
