摘要:21世紀(jì)是危機(jī)與發(fā)展共存的時(shí)代，能源匱乏、氣候變暖、環(huán)境污染等問題無時(shí)無刻不在困擾著人們，但隨著科學(xué)技術(shù)的不斷突破，人們不斷地打破枷鎖，為人類的生存與發(fā)展做出了卓越的貢獻(xiàn)，尤其是新能源的相關(guān)技術(shù)突破，使得新能源的利用越來越廣泛，為人們的未來發(fā)展展現(xiàn)了一條康莊大道。隨著太陽能技術(shù)的不斷突破，太陽能的利用也多姿多彩起來，作為技術(shù)最成熟、利用最方便的太陽能熱水器，以諸多優(yōu)點(diǎn)受到了人們的喜愛。太陽能熱水器的出現(xiàn)，不僅減少了資源的浪費(fèi)、節(jié)約能源，也為人們的日常生活提供了便利。 如何更加簡潔方便地使用太陽能熱水器，成為本文設(shè)計(jì)的出發(fā)點(diǎn)，結(jié)合太陽能熱水器的具體利用，在傳感器DS18B20、AT89C51單片機(jī)的基礎(chǔ)上，本文介紹了太陽能熱水器的工作原理和設(shè)計(jì)方案。利用AT89C51單片機(jī)設(shè)計(jì)太陽能熱水器智能控制儀，不僅能夠簡單地顯示時(shí)間與日期，更能夠利用LCD液晶顯示器顯示預(yù)設(shè)水溫與實(shí)際水溫?cái)?shù)值，簡單明了，根據(jù)預(yù)設(shè)水溫與實(shí)際水溫的差值，單片機(jī)智能判斷是否需要啟動(dòng)電輔助加熱器件，具有調(diào)節(jié)水溫的功能，當(dāng)預(yù)設(shè)水溫大于實(shí)際水溫時(shí)，自動(dòng)啟動(dòng)輔助加熱部件，提供更適宜的溫水，以使太陽能熱水器使用更加方便，方便人們?nèi)粘Ｉ顚崴男枨?，且該智能控制儀測量精度高，反應(yīng)靈敏，在水溫達(dá)到要求時(shí)，便立即停止加熱，相比其它的電加熱器件，如熱得快、電磁壺等，燒水可以減少大量能源損失。 關(guān)鍵詞 新能源；太陽能熱水器；傳感器；單片機(jī)
Abstract:The 21st century witnessed the coexistence of crises and development ,which is featured by the lack of energy、climate warming, environmental pollution human being faced for a long time. As the constant breakthrough of science and technology, we overcome the obstacles in the progress of development one by one for the sake of making great contributions to human survival and advances, especially innovations linked to techniques had paved the way for the extensive use of new energy which will open a new chapter for the future of mankind. The solar water heater, as the mature and most convenient tech-innovation, will be favored by people with its continued innovation in technology and a variety of applying. Solar water heaters not only reduce natural resource waste and save energy, but also offer convenience for people’s daily life. The usage of solar water heater with a simple and convenient way will be the starting point of this design. The paper, combined with the specific use of solar water heaters in the sensor DS18B20, AT89C51 micro-controller basis, described the working principle of solar water heaters and designing scheme. Intelligent control device of solar waters based on At89c51 MCU not only can easily display the time and date, but also can use LCD show the default water temperature and the actual temperature in a plain and simple way. By difference of water temperature and the actual temperature，SCM intelligent determined whether need to start the electric auxiliary heater parts and regulate the water temperature or not. When the water temperature was higher than the actual one, we should start automatically heating components so as to provide more comfortable hot-water and make solar water heaters more convenient and easier for our daily life. Also, the intelligent control instrument designed to be high-accuracy, and quick-witted. Still, to stop heating is necessary when the water temperature meet the requirements. Compared to other parts of electric heater, such as heater, electromagnetic pots, etc, boiling water can reduce energy losses. Keywords New Energy Solar Water Heaters Sensor Microcontroller |
