智能天然氣監(jiān)控終端的網(wǎng)絡(luò)通信系統(tǒng) 1 摘 要 生存環(huán)境的舒適與安全是人類永恒追求的物質(zhì)目標(biāo)。隨著計(jì)算機(jī)技術(shù)、通信技術(shù)、控制技術(shù)的飛速發(fā)展,人們對居住環(huán)境提出了更高的要求,希望居住在一個(gè)生活現(xiàn)代化,環(huán)境舒適化、安全化的生活空間。通過環(huán)境監(jiān)測系統(tǒng),用戶可以實(shí)時(shí)獲得居住環(huán)境的信息,如:溫濕度、天然氣濃度、火災(zāi)信息等。并將采集到的環(huán)境信息作為其他家庭設(shè)備運(yùn)行時(shí)的參數(shù),實(shí)現(xiàn)對環(huán)境的智能化控制。本終端作為智能家居的一部分,實(shí)現(xiàn)了實(shí)時(shí)監(jiān)測天然氣濃度和煙霧濃度,并且當(dāng)濃度超過設(shè)定閾值時(shí),將通過無線的方式進(jìn)行報(bào)警 智能終端 通過各種傳感電路檢測室內(nèi)的 天然氣 濃度 和 煙霧濃度 信息等 ,然后與預(yù)置的參數(shù) 閾值 進(jìn)行比較 , 智能終端 根據(jù)比較結(jié)果發(fā)出相應(yīng)的 報(bào)警信息,并且可以實(shí)時(shí)地顯示當(dāng)前時(shí)間室內(nèi)天然氣 濃度 和煙霧濃度信息 等參數(shù)值 ,并 可通過 WIFI, GPRS 等無線通訊方式及 時(shí)將各種監(jiān)控信息通知住戶 最后,本設(shè)計(jì)對以后研究工作的重點(diǎn)進(jìn)行了思考,提出了自己的見解。 關(guān)鍵字: 網(wǎng)絡(luò)通信, WIFI, 智能控制 , c語言 智能天然氣監(jiān)控終端的網(wǎng)絡(luò)通信系統(tǒng) 2 Abstract Comfortable and safe living environment of human eternal pursuit of the material goals. With puter technology, munications technology, control technology rapid development, people39。s living conditions put forward higher requirements, want to live life in a modern, fortable environment, security of living space. Through environmental monitoring system, users can obtain realtime information about the living environment, such as: temperature, humidity, gas concentration, fire information. And environmental information collected for other household equipment runtime parameters to achieve intelligent control of the environment. The terminal as a part of the smart home, realtime monitoring of gas concentrations and smoke density, and when the concentration exceeds the threshold value, the alarm by wireless means Intelligent terminal through a variety of sensing circuits of the gas concentration detection chamber and smoke density information, and with the preset threshold parameter value, based on the parison result of the intelligent terminal to issue the corresponding alarm information, and can display the current time in real time gas concentration in the indoor and smoke density values for parameters such information, and through WIFI, GPRS and other wireless munications in a timely manner all kinds of monitoring information to the tenants Finally, the design focus of future research work thinking, put forward their own views.
