PAGE II 基于单片机的智能开关设计 摘 要 近年来随着计算机在社会领域的渗透和大规模集成电路的发展，单片机的应用正在不断地走向深入，由于它具有功能强，体积小，功耗低，价格便宜，工作可靠，使用方便等特点，因此特别适合于与控制有关的系统，越来越广泛地应用于自动控制，智能化仪器，仪表，数据采集，军工产品以及家用电器等各个领域，单片机往往是作为一个核心部件来使用，根据具体硬件结构，以及针对具体应用对象特点的软件结合，以作完善。 本设计主要研究智能开关给家居带来便利。主要以单片机AT89C52为控制核心控制作息时间及空调温度监控报警，结合相关的元器件，如DS18B20，MAX7219，数码管，继电器。蜂鸣器等，再配以相应的软件设计，达到制作简易智能开关的目的。 关键词：单片机；AT89C52；智能开关；DS18B20 Intelligent switch based on single-chip design Abstract In recent years, with computers in the infiltration and the development of large-scale integrated circuits. SCM application is steadily deepening, as it has strong function, small size, low power dissipation, low prices, reliable, easy to use features, it is particularly suited to and control of the system, increasingly widely used in automatic control, intelligent instruments, gauges, data acquisition, military products and household appliances, and other areas, is often microcontroller as a core component to use, In light of specific hardware architecture, and application-specific software features object combine to make perfect. The intelligent design research to facilitate the switch to bring home. Mainly for the control of single-chip core AT89C52 schedule control and air-conditioning temperature monitoring alarm, combined with related components, such as DS18B20, MAX7219, LED, relay. Buzzer, etc., together with the corresponding software design, to achieve the production of mini-mental purpose of switching.
