1、定时开关插座毕业论文 定时开关插座毕业论文基于单片机的定时开关插座设计定时开关插座毕业论文 摘 要随着家用电器的越来越普及和人们生活节奏的加快，人们对电器的依赖性进一步提高，对电器的定时需求也进一步增大。定时开关插座可用于电饭煲、饮水机、电视机、电脑、电动车电池的充电、定时开关电热毯等需要定时供电的场合。定时开关插座的使用能够做到节能、安全、方便等。本文介绍了一种基于 AT89S52 单片机的定时开关插座设计方案。该系统是通过AT89S52 的定时器 0 和定时器 1 实现时钟的 24 小时制或者 100 小时制的时钟走时，并通过液晶 12232 显示出来。继电器的通、断通过比较继电器控制变量
2、 ray 的值来确定。定时时间的开始或者停止是通过每分钟比较一次开始时间数组 begin 和结束数组 end 来确定，并在开始时对 ray 进行加 1 操作，在结束时对 ray 进行减 1 操作(ray 的值不会出现负值) ；当 ray 为 0 时继电器开关断开，非 0 时接通。通过控制继电器的通断可以达到控制插座通断的目的。本文首先介绍定时开关插座设计要实现的功能，接着阐述系统电路的设计及原理说明，包括设计方案选择、关键元器件介绍、电路设计说明（包括电源电路、键盘、单片机控制电路、液晶 12232 显示、继电器工作电路）软件设计流程以及系统的测试。最后总结了定时开关插座设计完成的任务，分析系

Socket timer swi
4、tch can be used in the occasions where need for regular supply such as rice cookers, water dispenser, TV, computer, electric vehicle battery charging, timer switch electric blankets. The use of socket timer switch can be energy saving, safe, healthy, and convenient and so on.This article presents a
5、timer switch socket design which is based on the AT89S52 microcontroller. The system is implemented the clock 24-hour clock or 100-hour travel time by Timer 0 and Timer 1 of AT89S52, and it is displayed through the LCD 12232. Relay links, broken by comparing the value of the relay control variables
6、to determine the ray. It is to be determined the starting or stopping of regular time by compared per minute a start time with begin and an end array with end ,at the beginning of the ray to add an operation, at the end of the minus 1 on the ray action (rays value does not a negative); when ray is 0
