西安工业大学 题目： 系 ： 专 业： 班 级： 学 生： 学 号： 指导教师： 2012年月 单片机，亦称单片微电脑或单片微型计算机。它是把中央处理器（CPU）、随机存取存储器（RAM）、只读存储器（ROM）、输入/输出端口（I/0）等主要计算机功能部件都集成在一块集成电路芯片上的微型计算机。本设计是基于单片机的，利用7段共LED作为显示器件。在此设计中共接入了1个四位一体段共LED显示器2个两位一体7段共LED显示器，前者用来记录赛程时间其中2位用于显示分钟，2位用于显示秒钟，后者用于记录甲乙队的分数，每队2个LED显示器显示范围可达到099分。赛程计时采用倒计时方式，比赛开始时启动计时，直至计时到零为止。其次，为了配合计时器和分器调整时间比分，在本设计中设立了个按键，用于时间，调整分数和等功能。采用单片机控制这个系统操作使用简洁LED显示，安装方便。主控芯片采用单片机，采用C语言进行编程，编程后利用Keil uVision 来进行编译，再生成的HEX文件装入芯片中，采用proteus软件来仿真，检验功能是否能够正常实现。仿真成功后，焊接硬件电路，通过ISP下载器将hex文件烧制到单片机。 MCU based intelligent score device design Abstract Single chip, also known as the single chip microcomputer or single chip microcomputer. It is a central processor (CPU), random access memory(RAM), read-only memory(ROM),input/output(I/O)and other major computer components are integrated on a single integrated circuit chip microcomputer. The design is based on the STC89c52single-chip intelligence score device design, the use of 7total LED display,2 of two in one of 7 sections of a total of LED display, the former is used to record the race time,2of them for the show minutes,2of displaying the seconds, the latter is used for recording the B team score, each team of 2LED display range can achieve 0to99.Schedule a time with the countdown, match to start the beginning of time, until the time to zero. Secondly, in order to cooperate with the timer and the scoreboard to start and adjust the time and score, in the design of the establishment of 8keys, for starting and stopping time, adjusted scores and initialization function. Using single chip microcomputer control makes this system operation simple, LED display, convenient installation. The main control chip using STC89C52 single chip, using C language programming, programming with Keil uVision2 to compile, generating HEX files into chip, using Proteus Software to simulation, testing whether the normal implementation of function. After the success of welding simulation, hardware circuit
