【摘要】：伴隨著世界經(jīng)濟(jì)的高速發(fā)展,人們的生活水平有了顯著提高,但同時(shí)帶來(lái)的特別是氣體環(huán)境污染問(wèn)題也越來(lái)越受到人們的重視,比如大氣中的污染氣體、室內(nèi)裝修時(shí)的甲醛氣體、天然氣中的CO等有毒有害氣體時(shí)刻在威脅著人們的健康,室內(nèi)環(huán)境溫度、濕度等因素影響著家居的舒適度。其中智能家居室內(nèi)環(huán)境監(jiān)測(cè)系統(tǒng)作為智能家居的一個(gè)子系統(tǒng)是必不可少的,智能家居室內(nèi)環(huán)境監(jiān)測(cè)系統(tǒng)作為智能家居的前端監(jiān)測(cè)端,為其他子系統(tǒng)的工作提供數(shù)據(jù)支持。目前為了能夠?qū)崟r(shí)監(jiān)測(cè)智能家居室內(nèi)環(huán)境有毒有害氣體的參數(shù),各種相關(guān)技術(shù)也在不斷發(fā)展,但要想實(shí)現(xiàn)智能家居系統(tǒng)中的室內(nèi)環(huán)境監(jiān)測(cè)系統(tǒng)的普及仍然存在著眾多的問(wèn)題,主要原因包括成本高、監(jiān)測(cè)精度不高、信號(hào)傳輸不穩(wěn)定等。針對(duì)上述問(wèn)題,本文設(shè)計(jì)了一套通過(guò)Wi-Fi技術(shù)實(shí)現(xiàn)的精準(zhǔn)度高、成本低等諸多優(yōu)點(diǎn)的室內(nèi)環(huán)境監(jiān)測(cè)系統(tǒng),該系統(tǒng)的監(jiān)測(cè)前端載有自主研制的甲醛傳感器,該監(jiān)測(cè)單元的靈敏度極高。其中信息的傳輸方式選用的是傳輸信息穩(wěn)定、傳輸距離遠(yuǎn)的Wi-Fi技術(shù),前端監(jiān)測(cè)電路可以實(shí)時(shí)監(jiān)測(cè)每個(gè)單元的溫度、濕度、甲醛濃度、CO濃度等環(huán)境參數(shù),只要有一臺(tái)能連上Internet網(wǎng)絡(luò)的PC機(jī),就能實(shí)現(xiàn)PC機(jī)的遠(yuǎn)程實(shí)時(shí)觀測(cè)被觀測(cè)點(diǎn)的環(huán)境參數(shù)情況。本系統(tǒng)中的前端監(jiān)測(cè)系統(tǒng)的硬件電路設(shè)計(jì),根據(jù)設(shè)計(jì)的需求、功能實(shí)現(xiàn)要求、硬件成本、功耗和性能等諸多方面考慮,選定了微處理器芯片、模數(shù)轉(zhuǎn)換芯片、甲醛傳感器敏感材料、CO傳感器探頭、溫濕度傳感器等,并最終設(shè)定了MCU最小系統(tǒng)電路、甲醛監(jiān)測(cè)模塊電路、CO監(jiān)測(cè)模塊電路、溫濕度監(jiān)測(cè)模塊電路、報(bào)警電路、顯示電路、電源轉(zhuǎn)換電路等。本系統(tǒng)中軟件設(shè)計(jì),在下位機(jī)硬件電路系統(tǒng)的基礎(chǔ)上,設(shè)計(jì)了下位機(jī)軟件系統(tǒng),在下位機(jī)硬件和軟件配合下,實(shí)現(xiàn)了下位機(jī)能夠?qū)崟r(shí)監(jiān)測(cè)室內(nèi)某單元空氣環(huán)境參數(shù)的功能。并且通過(guò)Wi-Fi模塊與控制程序的結(jié)合實(shí)現(xiàn)了下位機(jī)與上位機(jī)的信息通信。上位機(jī)Web界面的設(shè)計(jì)是基于SpringMVC3+Hibernate3開(kāi)發(fā)軟件和Oracle11g數(shù)據(jù)庫(kù)進(jìn)行開(kāi)發(fā)實(shí)現(xiàn)的。該上位機(jī)系統(tǒng)具有信息存儲(chǔ)、實(shí)時(shí)監(jiān)測(cè)、查詢(xún)等功能。最后通過(guò)對(duì)整體智能家居室內(nèi)環(huán)境監(jiān)測(cè)系統(tǒng)的測(cè)試,結(jié)果顯示本文設(shè)計(jì)的監(jiān)測(cè)系統(tǒng)運(yùn)行平穩(wěn),滿(mǎn)足設(shè)計(jì)要求。
[Abstract]:With the rapid development of the world economy, people's living standard has been improved significantly, but at the same time, the problem of gas environment pollution has been paid more and more attention, such as the polluted gas in the atmosphere. Formaldehyde gas in indoor decoration and CO in natural gas are threatening people's health at all times. Indoor temperature humidity and other factors affect the comfort of the home. As a subsystem of smart home, intelligent home indoor environment monitoring system is essential. As the front end of intelligent home, it provides data support for other subsystems. At present, in order to monitor the parameters of indoor toxic and harmful gases in real time, a variety of related technologies are developing, but there are still many problems to realize the popularization of indoor environment monitoring system in smart home system. The main reasons include high cost, low monitoring accuracy, unstable signal transmission and so on. Aiming at the above problems, this paper designs a set of indoor environment monitoring system which has many advantages such as high precision, low cost and so on, which is realized by Wi-Fi technology. The front end of the system contains formaldehyde sensor, which is developed by oneself. The sensitivity of the monitoring unit is very high. Among them, the transmission mode of information is Wi-Fi technology with stable transmission information and long transmission distance. The front-end monitoring circuit can monitor the environmental parameters such as temperature, humidity, formaldehyde concentration and CO concentration of each unit in real time. As long as there is a PC connected to the Internet, the remote real-time observation of the environmental parameters of the observed point can be realized on the PC. The hardware circuit design of the front-end monitoring system in this system, according to the requirements of the design, function realization requirements, hardware cost, power consumption and performance, the microprocessor chip, A / D conversion chip is selected. The sensitive material of formaldehyde sensor is CO sensor probe, temperature and humidity sensor, etc. Finally, MCU minimum system circuit, formaldehyde monitoring module circuit, CO monitoring module circuit, temperature and humidity monitoring module circuit, alarm circuit, display circuit, etc. Power conversion circuit, etc. The software design of this system is based on the hardware circuit system of the lower computer, and the software system of the lower computer is designed. With the cooperation of the hardware and software of the lower computer, the function that the lower computer can monitor the air environment parameters of a unit in real time is realized. The information communication between the lower computer and the host computer is realized by the combination of the Wi-Fi module and the control program. The design of upper computer Web interface is based on Spring MVC3 hibernate 3 development software and Oracle 11g database. The upper computer system has the functions of information storage, real-time monitoring, query and so on. Finally, through the testing of the whole intelligent home indoor environment monitoring system, the results show that the monitoring system designed in this paper runs smoothly and meets the design requirements.
