Research And Development Of Intelligent Home Environment Monitoring System

With the rapid development of world economy,people's living standard has been greatlyimproved,of course,with the development of economy,environmental problems emerge in an endless stream,especially the gas environment pollution is becoming more and more serious,such as formaldehyde,indoor decoration of the natural gas in CO gas and other toxic and harmful gases threaten people's health.The intelligent Home Furnishing indoor environmental monitoring system as a subsystem of intelligent Home Furnishing is essential,Home Furnishing intelligent monitoring system for indoor environment monitoring as the front end intelligent Home Furnishing,provide data support for other subsystems work.The order parameters can be real-time monitoring of intelligent Home Furnishing indoor environment of toxic and harmful gases,related technology is also in constant development,but to realize the popularization of the indoor environment monitoring system of intelligent Home Furnishing in the system there are still many problems,the main reasons include high cost,monitoring precision,signal transmission is not stable.Aiming at the above problems,this paper designs a set of indoor environmental monitoring system through the Wi-Fi technology to achieve high accuracy,low cost,monitor the system containing formaldehyde sensor developed,high sensitivity of the monitoring unit.The information transmission of the information transmission is stable,Wi-Fi transmission distance,the front-end monitoring circuit of each unit can be real-time monitoring of temperature and humidity,formaldehyde concentration,CO concentration and other environmental parameters,as long as there is a computer connected to the Internet network PC machine,can realize remote real-time observation by PC the observation point of environmental parameters.The front-end monitoring system in this system according to the design requirements,function requirements,hardware cost,power consumption and performance and other aspects to consider,selected microprocessor chip,analog digital conversion chip,formaldehyde sensor sensitive materials,CO sensor probe,temperature and humidity sensors,and finally set the minimum system circuit of MCU module circuit,formaldehyde monitoring CO monitoring module circuit,temperature and humidity monitoring module circuit,alarm circuit,display circuit,power conversioncircuit etc..This system based on the hardware circuit of the system,design the software system,the hardware and software cooperation,realize computer real-time monitoring of indoor air environment parameters of the function of a unit.Through the combination of Wi-Fi module and control program,the information communication between the lower computer and the host computer is realized.The design of Web interface of host computer is based on SpringMVC3+Hibernate3 development software and Oracle11 g database.The host computer system has the functions of information storage,real-time monitoring,query and so on.Finally,the test results show that the monitoring system designed in this paper can run smoothly and meet the design requirements.
