本次实践地点为陕西中工电子市场---西安市佳亿电子公司，主要实践项目是亲手制作基于单片机（MCU）的彩灯音乐盒以及复习可编程逻辑控制器（PLC）相关知识并且练习用汇编语言为单片机编程（MCU），梯形图或语句表（LAD/STC）为可编程逻辑控制器（PLC）进行编程。

This practice location for shaanxi zhonggong electronics market - xian jia billion electron company, main practice project is made based on single-chip hand MCU of colored lights music box and review the programmable logic controller (PLC) related knowledge and practiced written in assembly language for microcontroller programming (MCU), ladder diagram or statements table (LAD/STC) for programmable logic controller (PLC) for programming.

实践时间为2011.02.24至2011.03.05，参加人员***6人：实践小组组长：杨楠；

Practice time for 2011.02.24 to 2011.03.05, participants, a total of six people: practice team leader: YangNan;

实践小组组员：蒲昕，孙嘉亮，陈凯，张博，刘伟。

Practice team members: PuXin, SunJiaLiang, ll, ZhangBo, liu wei.

实践项目分为两个部分即单片机音乐盒制作，与可编程逻辑控制器的复习、编程；

Practice project is divided into two parts namely music box production, and SCM (programmable logic controller to review, programming,

其中第一部分采用两种方案即：硬件发生与软件发生。

Among them the first part adopts two schemes namely: hardware occurrence and software occurred.

设计流程分为：硬件电路设计，程序流程图编写，程序编写，仿真，面包板调试及焊接电路：由杨楠、孙嘉亮、陈凯完成硬件设计，蒲昕、杨楠、刘伟、张博完成软件编程，杨楠、蒲昕完成电路仿真，面包板调试，焊接电路由六人***同完成（仿真软件利用PROTEUS，方案2音乐程序编码利用MusicEncode软件完成，下载程序利用STC_ISP_V486软件）；

The design process is divided into: hardware circuit design, program flowchart compile, programming, simulation, bread board debugging and welding circuit: YangNan, by SunJiaLiang, ll complete hardware design, PuXin, YangNan, liuwei, ZhangBo accomplish software programming, YangNan, PuXin complete circuit simulation, bread board debugging, welding circuit by six people together to achieve (simulation software USES PROTEUS, music program code utilization plan 2 MusicEncode software, download a program using STC_ISP_V486 software);

第二部分利用梯形图进行直观的编程，项目为花样彩灯控制，整个过程有六人***同完成。

The second part use ladder diagram are the direct programming, projects for the figure, the whole process of lights control six people together to achieve.

将所编程序写入STEP7-MicroWin SP6西门子S7-200专用编程软件进行梯形图的编程并进行梯形图与语句表之间的转化。

Will have programmed into MicroWin STEP7 - SP6 Siemens S7-200 special programming software ladder-diagram programming and ladder diagram and watch the conversion between statements.

实践期间实践小组查阅了大量的单片机与PLC资料，通过此次实践，熟悉了单片机设计的流程，并且复习了利用汇编语言编程的相关知识，并对利用C语言对单片机进行编程做了初步的了解。

Practice during practice team looked a lot of single-chip microcomputer and PLC material, through the practice, familiar with the SCM design process, and review the use assembly language programming, and the related knowledge of using C language program of single-chip processor is made a preliminary understanding.

同时对于可编程逻辑控制器的相关知识做了简略的复习回顾。

At the same time for programmable logic controller related knowledge of made the brief review review.
