摘 要本文所介绍的电饭锅电子保姆仪，是继普通家庭电饭锅之后所产生的新型智能化电饭锅。设计研制了一个智能化的电饭锅系统，在继承以往电饭锅的优点同时加入了定时进水与定时煮饭功能，达到根据制定时间开始煮饭，并在规定时间内把饭煮熟切自动停止工作功能。设计采纳温度传感器 DS18B20 采集温度，通过单片机的低电压输出来控制继电器的关断，从而达到控制关闭进水阀、自动电路断开效果，并且具有显示功能，能将工作的状态随时间而显示在液晶显示器上，整个过程通过单片机来控制。本文介绍了一种新型的电饭锅控制系统，详细介绍了设计的总体思想、硬件设计与软件系统，系统而详细地对该系统的功能与实现做出了介绍，并对该设计提出了不足与改进。关键词：单片机控制；定时功能；继电器控制；传感器AbstractThis article introduces the rice cooker electronic nanny instrument, and is the ordinary household rice cooker after the rice cooker produces a new type of intelligence. The design and development of an intelligent system rice cooker, rice cooker in the past, the advantages of inheriting the same time joined the regular water and regular cooking function, time to start cooking under development, and the rice is cooked within the specified time stop automatically cutting function. Design uses a temperature sensor DS18B20 collecting temperature, low-voltage output by the microcontroller to control the relay off, and thus to control the closed inlet valve, disconnect the effect of automatic circuit, and has display function, the state can work over time shows on the LCD monitor, through the microcontroller to control the whole process.This paper introduces a new type of rice cooker control system detailed design of the overall idea, hardware design and software system, the system and detailed functions and implementation of the system made a presentation and the design of a lack of and improvement.Keyword: MCU; Timing; Relay control; Sensor 目...
