基于单片机的电子表设计
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，在根据具体硬件结构，以及针对具体应用对象特点的软件结合，以作完善。
本次做的电子表是以单片机（AT89S51）为核心，结合相关的元器件（共阴极LED数码显示器、BCD-锁存/7段译码等），再配以相应的软件，达到实现时钟日历显示的功能，也具有日历计算、显示和时钟、日历的校准，以及多路开关定时输出等功能，其硬件部分难点在于元器件的选择、布局及焊接。
Based on the design of electronic SCM
Abstract: In recent years, with computer penetration in the social sphere and the development of large-scale integrated circuits, MCU applications are constantly deepening, as it has a function of strong, small size, low power consumption, cheap, reliable, Easy to use, and other characteristics, and therefore particularly suited to control the system, more widely used in automatic control, intelligent instruments, meters, data acquisition, military products and household appliances, and other fields, the MCU is often as a core Parts to use, in accordance with specific hardware and application-specific characteristics of the object with software to make perfect.
This is done in electronic form SCM (AT89S51) as the core, the combination of related components (of cathode LED digital display, BCD-latch / 7 of the decoder, and so on), Coupled with the corresponding software, to achieve Clock calendar shows that the function of the calendar also calculated, display and the clock, the calendar of calibration, and multi-channel Kaiguandingshi output, and other functions, some of its hardware components is difficult choice, layout and welding.

本毕业设计课题是属于教师拟定性课题，主要是研究基于单片机的对步进电机的有效控制。步进电机是一种能将数字输入脉冲转换成旋转或直线增量运动的电磁执行元件，每输入一个脉冲电机转轴步进一个步距角增量。电机总的回转角与输入脉冲数成正比例，相应的转速取决于输入脉冲频率。
步进电机是机电一体化产品中关键部件之一，通常被用作定位控制和定速控制。步进电机惯量低、定位精度高、无累积误差、控制简单等特点。广泛应用于机电一体化产品中，如：数控机床、包装机械、计算机外围设备、复印机、传真机等。

Abstract
This article mainly elaborated has been hanging the movement control system merit, introduced was hanging the movement control system function, the principle and the design process. Is hanging the movement control system is one of in control engineering domain important applications, its main target is to is controlled the object the movement condition, including path, speed and position implementation check. The movement control system compares with other control systems, has the system model simply, the check algorithm is unitary, also not complex characteristic and so on non-linearity and coupling situation. Also is precisely because the movement control system can implement to the path, the running rate, the pointing accuracy as well as the repetition precision accuracy control requirement, has the broad application foreground in each category of control engineering, therefore the movement control system has at present become in the check study application domain very much significant the research direction. Through the monolithic integrated circuit to stepping monitor check, implemented the motor-driven to cause the object at on the board which inclined the movement, The control section is the SST89E52 monolithic microcomputer which SST Corporation produces primarily, with when the 1602LCD liquid crystal screen and according to turned has implemented with the user interactive, through the keyboard entry different control command, the liquid-crystal display was allowed to display the setting value and the run the coordinates. The electrical machinery control section used LM324N four to transport puts and is connected the electronic primary device voluntarily to develop the 42BYG205 stepping monitor actuation electric circuit to implement the electrical machinery accuracy control. The algorithm partially for will suit the monolithic integrated circuit system to operate carries on optimizes many times, will reduce the microprocessor the operand. Has completed the object voluntarily the movement and according to the different setup path movement.
Key words Magneto; 1602LCD; LM324N; Drive circuit
