SomachineA刷新程序说明1、Somachine对文件是以工程以及工程存档来管理的。

●工程文件(.project)：具有图标，可以双击直接用Somachine打开，属于可执行文件，具有友好性的特点。

但是因其首次在陌生的PC平台中使用时会导致库文件的丢失而报错，造成无法编译等错误，使其可移植性不够好。

●工程存档文件(.projectarchive)：其与工程文件(.project)是两个不同的概念。

工程存档文件可以解压出工程文件，甚至包括该程序所需硬件的库，可移植性好。

●首次分发文件时，将以工程存档文件(.projectarchive)下发。

2、下载操作（下装）：a)连接好PLC到PC的USB编程电缆，开启PLC电源，PC将自动安装M218的驱动，M218在RUN模式也可以下装程序；b)打开Somachine软件；c)依次单击“主页——显示现有机器——提取存档”，在弹出的“提取存档”对话框里选择工程存档文件(.projectarchive)的位置，并单击“打开”；d)在弹出的“工程存档”对话框里，勾选存档内容栏里面所有出现的选项。

并点击“解压”。

解压的位置在常规栏里设置，一般默认即可，若以后要清理垃圾，可记住这个目录；e)点击解压后，将弹出Somachine问题对话框。

勾选“应用于全部条目和文件”，覆盖存在的条目和文件，并点击“Yes”；该对话框可能会出现多次，每次均重复本条的操作；f)上述的操作后，将选项卡从“属性”切换到“程序”；g)点击出现的工具栏里的“在线——登录到‘Application[MyController:PLC]’”；h)如果弹出如下对话框，请点击确定；i)然后在“MyController——通讯设置”的选项卡中，点击“添加网关…”，将弹出网关对话窗，直接“确定”。

j)点击“扫描网络”按钮，并等待该按钮变成可操作状态。

然后点击，等待前面出现展开符号，然后点击展开所有项目，选中展开的最底层的(M218)SN ******[****.****]，变深色，如下图所示：k)点击“设置使用路径”，在弹出的“警告”窗口后，按组合键“AL T+F”，即可，如下图；不相同，将弹出如下窗口，请选择“登录并下装”，确定即可；下装之前，该平台将自动对程序进行编译并生成代码。

jsj第4次作业-测控1302-马天奥-U201310852-计算思维论文华中科技大学《论大学生与计算机思维》——大学生计算机基础第4次作业班级测控（精密）1302班学号 U201310852姓名马天奥指导教师黄晓涛2013年11月27日星期三目录一．摘要·3二．正文1.关于计算思维的思考 (3)2.计算机教学应当培养学生的三种能力 (4)三．结束语 (6)四．参考文献 (7)摘要：计算机基础教学是培养大学生综合素质和创新能力不可或缺的重要环节。

本文分析了当前计算机基础教学的新形势以及计算思维与大学生结合的重要性，重点讨论大学生计算思维的培养。

关键字：计算思维大学生能力培养关于计算思维的思考李廉教授指出：计算思维是人类科学思维固有的组成部分，以可行和构造为特征。

计算思维表达构造和操作，因为对于人的集体行为，需要一个群体的共同理解，因此要具有以下的特征，有限性（可表述性）、确定性（无歧义性）、机械性（不因人而异）[5]。

Richard m. carp教授提出的“计算透镜”（computational lens）理念也提出要将计算作为一种通用的思维方式 [6] ，通过这种广义的计算（涉及信息处理、执行算法、关注复杂度）来描述各类自然过程和社会过程，从而解决各个学科的问题。

这一理念试图将计算机科学由最初的数值计算工具、仿真与可视化技术以及后来基于网络、面向多学科的e-science平台，变成普遍适用于自然和社会领域的通用思维模式。

计算科学是一门正在兴起的综合性学科，它依赖于先进的计算机及计算技术对理论科学、大型实验、观测数据、应用科学、国防以及社会科学进行模型化、模拟与仿真、计算等。

特别是对极复杂系统进行模型与程序化，然后利用计算机给出严格理论及实验无法达到的过程数据或者直接模拟出整个复杂过程的演变或者预测过程的发展趋势。

对基础科学、应用科学、国防科学、社会科学以及工程技术等的发展有着不可估量的科学作用与经济效益。

JSJ-GL型爬架控制系统使⽤说明书JSJ-GL型爬架控制系统使⽤⼿册JSJ-GL型爬架控制系统使⽤说明书⼀、系统概述JSJ-GL型爬架控制系统综合运⽤单⽚机和测⼒传感器测控技术，通过单⽚微型计算机对被提升脚⼿架的载荷进⾏综合分析并作出相应处理，实现了对脚⼿架的升降的全过程的实时监测和⾃动控制，使整个爬架的升降⾃如、快速、准确、安全，从⽽有效地保证了施⼯的优质进⾏。

JSJ-GL型爬架控制系统使⽤以总控和多台以单⽚微型计算机为核⼼的分控以及测⼒传感器组成的测量系统。

通过单⽚微型计算机对系统中各分控的载荷进⾏实时检测、实时报警、实时排障和实时控制，有效地保证了脚⼿架施⼯的快速、安全和准确。

系统特点：本系统采⽤两种控制⽅式：⼿动控制和遥控器控制，实现现场操作的简易化。

控制系统的控制线路采⽤并⾏的⽅式连接，解决了过去因分控线路出现故障⽽使整个控制信号⽆法传递给总控的状况。

同时各分控全部有单独控制动作，当分控的单⽚微型计算机检测到当前机位异常时，会⾃动发出相应的动作，并将信号传递给总控。

简单易懂易操作，操作者不需要懂得计算机知识，只要懂得⼀定的升降架的基本原理，就能很轻松地掌握该系统的操作。

本系统设计安全控制机位数为35台，如需增加机位，可根据⽤户要求定做。

⼆、爬架控制系统的原理、组成2.1基本原理本套系统采样的主要数据是机位的载荷数据，通过单⽚微型计算机实现各种状态的动作切换，控制的主要对象是三相交流电机。
