I家用自动升降吊灯单片机控制系统设计摘要：本毕业设计是家用自动升降吊灯单片机控制系统设计，本设计以AT89C51 控制器作为主控芯片，实现吊灯的升降操作。这个系统包括的部分有声光报警、模数转换、压力检测、显示部分、主控部分以及电源。显示电路采用LCD12864 显示数据。电机用的步进式电机，驱动用的 ULN2003，然后按键来进行控制。用 C 语言来进行软件的整个设计，用 keil 软件来编写程序和设计。当设计完成以后用 protues 仿真软件来进行最后的仿真。最后达到系统性能要求。论文主要从选题意义为开篇进行书写。首先对整个系统进行结构设计，制作出整体结构框图，然后对每个模块进行方案选择，确定各模块使用具体方案。等方案设计好以后，再对每一个模块做出硬件的电路选择，然后绘制出相应的电路图，完成对硬件电路的一个设计，随后进行每个模块软件的程序编写，从而达到每个设备的功能。最后就是对各个模块的仿真，验证各个模块软件的的功能，不断进行优化，完成整个设计内容关键词：AT89C51 单片机；LCD12864；ULN2003；步进电机Design of single-chip computer control system for automatic elevator droplightIIAbstract ： The graduation design is a home automatic chandelier single-chip control system design, the design to AT89C51 controller as the master chip, to achieve chandelier lift operation. This system includes parts of the sound and light alarm, analog conversion, pressure detection, display part, the main control part and power supply. Display circuit using LCD12864 display data. Motor stepper motor, drive with ULN2003, and then press the button to control. C language to the entire design of the software, with keil software to write programs and design. When the design is completed with protues simulation software to carry out the final simulation. And finally to the system performance requirements.The thesis is mainly written from the meaning of the topic. First of all, the entire system structure design, to create a block diagram of the overall structure, and then for ea...
