【正文】 摘 要 眾所周知，現(xiàn)階段我國的電力資源損耗十分巨大，而人們的生產(chǎn)及生活又少不了電力資源。以電力供應(yīng)為例，一些家用電器的耗電量是很大的，比如空調(diào)，電暖氣等。在本文中我將介紹一種新的節(jié)能的方法，通過以一片 STC89S52 為主控制器的單片機(jī)電路，采用分時控制，以達(dá)到被控制電器設(shè)備的工作與否。由于其體積小、成本低，計時準(zhǔn)確，功耗小，不僅適合嵌入到各種能耗大的工控設(shè)備中進(jìn)行控制，也適合居民的家用電器節(jié)能控制，而且節(jié)能效果顯著。t do without the electric power resource also of people. To the electricity supply as an example, some of the electricity consumption is a big household electrical appliances, such as air conditioning, heating, such as. Some of the power plant is truly large, such as aluminum, steel plant, and so on. In this article I will introduce a new energysaving method, mainly to a STC89S52 Controller MCU circuit, a timesharing control, to achieve control of electrical equipment was not working. This method is actually the core of a microcontroller based on the number of electronic bell, with the LED digital display, to display the actual time used keys and adjust the suspension to begin and end, a 6 MHz crystal, by setting a Initial precise timing, so to plete the precise time。single chip microprocessor。sound and light alarm III 目 錄 1 緒 論

眾所周知，現(xiàn)階段我國的能源缺口很大，而人們的生產(chǎn)及生活又少不了能源。有些工廠是名副其實(shí)的耗電大戶，如電解鋁﹑電解銅生產(chǎn)廠﹑煉鋼廠等。其中一個較好的方法就是分時控制作業(yè)。如果能將白天用電高峰期開動的一些設(shè)備改在夜晚用電低谷時期使用，則不僅可以大大減輕電網(wǎng)的負(fù)擔(dān)，而且還 可有效減少用戶的用電費(fèi)用。首先使用 Proteus 99SE 軟件進(jìn)行繪制硬件電路圖，用編譯軟件進(jìn)行編程與調(diào)試，最終生成 hex 文件，傳入單片機(jī)內(nèi)部，從而實(shí)現(xiàn)仿真效果?？稍O(shè)置鬧鐘，即定時時間到有報警裝置報警。而本設(shè)計最 重要的一點(diǎn)是當(dāng)用電高峰和低谷時，可自動開 /關(guān)，實(shí)現(xiàn)節(jié)能這一特點(diǎn)。如圖 圖 節(jié)能時控器模
