单片机SCMsinglechipSingle-Chip Microcomputer 有的时候，也可以用SingleChip来代替 -------------- 中文: 单片机是把主要计算机功能部件都集成在一块芯片上的微型计算机。它是一种集计数和多中接口于一体的微控制器，被广泛应用在智能产品和工业自动化上，而51单片机是个单片机中最为典型和最有代表性的一种。 本课题选择89S51为核心控制元件，设计了一个日常生活中用到的电子音乐门铃系统。当功能按键按下，音乐响起，发光二极管随着音乐的节拍进行闪烁，LED显示相应的定时器初值。音乐演奏过程中再次按下按键无效，只有当音乐段结束再次按下才有效。如果是电子音乐门铃在响，按下复位按键就终止，显示初始状态。经过实践证明，本系统运行稳定，具有一定的实用价值。 ------------- 翻译: SCM is a major piece of computer components are integrated into the chip micro- It is a multi-interface and counting on the micro-controller integration， and intelligence products are widely used in industrial and MCS-51 microcontroller is a typical and The topics chosen for the 89S51 control of the core components used in the design of a daily electronic music doorbell When the function button is pressed， the music sounded and the music beats with light emitting diodes for Initial corresponding LED Musical process again pressed the button ineffective， and only when pressed again before the end of the music If the doorbell ring for electronic music， press the button on the reduction and termination， showed initial Practice has proved that the system is stable and has some practical 本设计是以凌阳16位单片机为重心，介绍语音控制在机械手中的应用，实现微型舵机的运作，完成所指定的动作。其中通过凌阳16位单片机输出的脉冲信号来准确的控制机械手的摆动角度，机械手的捏拿动作由电磁铁完成，电磁铁的通断由凌阳16位单片机的I/O口控制，硬件和软件都在具体的实验中证明了其可行性This design is take insults the positive 16 monolithic integrated circuits as a center of gravity， introduced the pronunciation control in manipulator's application， the realization miniature servo operation， completes the movement which Through insults the pulse signal which the positive 16 monolithic integrated circuits outputs to come the accurate control manipulator to swing the angle， the manipulator pinches takes the movement to complete by the electro-magnet， the electro-magnet passes the legal reason for judgment to insult the positive 16 monolithic integrated circuits I/O control， the hardware and the software all have proven its feasibility in the concrete experiment
In recent years， with the rapid development of science and technology， the application of SCM is unceasingly In real-time detection and automatic control of microcomputer application system， its often as a core component to But only the microcontroller knowledge is not enough， should be based on the hardware structure， perfect soft Most current universities have established the microcontroller laboratory， basically equipped with experiment box and other hardware simulation But experiment box hardware circuit fixed， experiment content more difficult change， is hard to adapt to the rapid development of single chip microcomputer and cultivate students' SCM development ability， innovation Using the Proteus software simulation technology， can to a certain extent make up for the shortage， build a virtual experimental platform， can achieve more practice， provide students to learn to disciplinary construction of conditions， has a positive In view of this， this article based on the single-chip microcomputer simulation environment， Proteus MICOCHIP company by the PIC microcontroller as the main control chip series with data storage units， combined with peripheral infrared sensor， LCD display， temperature sensing， dc motors， heating DianLuSi， alarm equipment， written in C control program main control chip design combines a automatic temperature monitoring and artificially infrared temperature adjustment is an organic whole， have alarm function of temperature control This design fully exert Proteus characteristics， reduce the cost and enhance practicability， benefit in university
First， the current design is based on graduation MCU control SCM introduced to the main components of the monitoring system and the architecture， design and principle， the realization of the automatic control system， for the normal operation of equipment for the Secondly， The graduation address system design used by the C8051F020 the performance and development of a comprehensive done presentation; Then right DS18B20 single-bus digital temperature sensor made of the performance; UART0 while on the way serial communication function and the analysis; Finally， SCM interference measurement system hardware and software design method also be The graduate design major applications C8051F020 microcontroller as a core element in the analysis and design on the part of the circuit was After repeated and the simulation running， debugging， revision， the final form of a complete set of procedures Practice has proved that the system stability， and they have the advantage of a simple hardware circuits， software functions， reliable control system， high cost performance， is practical and reference Finally， at the graduation design process also involving the powerful Protel99 SE software use， and the use of this software mapping diagram of the system， the PCB Keywords : microcontroller， temperature sensor， serial communication， interference， Protel99 SE
