【正文】 基于單片機的燈控系統(tǒng)設(shè)計 I 基于單片機的燈控系統(tǒng)設(shè)計 摘 要 隨著人們生活水平的不斷提高，人們對生活環(huán)境的舒適程度要求也越來越高。當一天繁忙的工作結(jié)束之后，需要一個輕松舒適的環(huán)境來讓人們放松心情。而燈光在家庭環(huán)境中占有很大一部分，能夠隨意控制燈光成了人們共同的要求。 本文闡述了 遙控技術(shù)的發(fā)展和應(yīng)用，為我們的生活帶來的諸多方便之處。在遙控技術(shù)中主要闡述了紅外遙控技術(shù)在本設(shè)計中的應(yīng)用。在本設(shè)計中，通過紅外遙控和單片機的相互結(jié)合設(shè)計的燈光控制系統(tǒng) ，該系統(tǒng)是基于單片機的控制系統(tǒng)，用遙控的方式對系統(tǒng)燈光進行控制。本人設(shè)計了遙控接收模塊，過 零檢測電路，電源電路， 調(diào)光控制電路等幾個重要部分。本設(shè)計主要解決了信號的接收和處理，通過各部分電路控制燈光亮度的調(diào)節(jié)。 該系統(tǒng)設(shè)計簡單，維護方便，制作成本不高，特別適應(yīng)于家庭使用。 關(guān)鍵 詞 單片機 8051 紅外遙控 雙向可控硅 基于單片機的燈控系統(tǒng)設(shè)計 II Lighting control system based on single chip design Abstract With the continuous improvement of living standard, people39。s living environments demand more and more fort. When after a busy day of work, you need a relaxed and fortable environment to allow people to relax. The lighting in the home environment plays a large part, to freely control the lights have bee a mon requirement. Q expounded on the remote control technology in the development and application of life, we provide for the production and livelihood of the many convenient, remote control technology in the main paper, the infrared remote control in the design of the application. This paper is through remote control technology and MCU intargeted lighting control system, The system is based on the puter39。s control system， remotecontrolled manner to control lighting system. This article is designed remote control receiver module, the zero detection circuit, power circuit, dimming control circuit, and several important parts. This design solves the signal receiving and processing part of the circuit through the control of light brightness adjustment. The system is designed to be simple, easy maintenance, low production costs, especially suitable for home using.
