Further more we build the control command channel based on tcp protocol to assure the credibility transmission of the control command and approve the transmission performance of multimedia data . the education functions of this project include screen image broadcasting , electron roll calling , electron raising hands , net cinema , file transmission etc . in order to increase the interactive function , the net - classroom teaching control protocol ( ntcp ) was extended by locking , unlocking , remote shutting down and remote restarting etc 在强化教学功能方面,增加了包括电子白板,电子举手,网上影院,文件传输等实用功能,并对原有电子点名、锁定键盘鼠标等功能做了进一步的改进。在交互控制方面,进一步扩充了原有网络教学控制协议( ntcp ) ,实现了锁定,解锁,远程关机,重启等交互控制。
The record module manages lower modules periodically , receives and records alarm messages sent through the bus , outputs control commands to control modules according to configuration parameters , controls related executive modules . the parameters of the bus nodes can be setup and displayed through the record module 记录模块定时管理下位各模块,接收并记录总线上传来的报警信息,根据组态参数,输出控制信息到控制模块,控制相应执行机构,同时能够通过键盘设置总线节点参数并显示。
In one side , users send the control commands to remote robot in local place , and the system of remote robot explains and executes the commands , and the controlled robot finishes the correspond motion ; on the other hand , the remote video cameras grab the spot images and transmit them to the remote controller in real time 一方面,用户在本地发送控制命令给远端的机器人,由远端机器人系统对控制命令加以解释、执行,从而控制机器人完成相应的动作;另一方面,由远端的摄像机把现场的图像加以采集,并实时传输到远程控制方。
Being the import unit of the distribution automation system , the transformer terminal unit namely ttu , samples ac input ( such as voltage , current and so on ) and state ( for example : switch state ) and executes remote control command ( open operation or close operation ) , ttu supervise the action of transformer , so it guarantee the security of das ( distribution automation system ) this paper is mainly based on the study of transformer terminal unit based on msp430f449 scm , the work of this paper includes : first , introduces the design of the hardware system and the software system of ttu , the core mathematical principle , and then , discusses the implementation of the communication protocol : iec870 - 5 - 101 and i2 c in detail 配变监测终端ttu ( transformerterminalunit )是配电自动化系统中的重要部分,在系统中完成采集模拟量(电压、电流等)和状态量(如开关状态) ,以及执行遥控(开、合操作)操作等功能,实现对配电变压器的实时监测,保障配电系统的可靠运行。本文主要研究了基于msp430f449单片机的配电监测终端的实现,较详细地介绍了系统的硬件设计、软件设计、核心算法,介绍了通讯规约iec870 - 5 - 101和i ~ 2c的实现。
Being the core unit of the distribution automation system , the feeder terminal unit , namely ftu . samples ac input ( such as voltage , current and so on ) and state ( for example : switch state ) and executes remote control command ( break or close ) . this paper is mainly based on the study of feeder terminal unit based on dsp 馈线自动化终端装置( feederterminalunit )是馈线自动化系统中的核心部分,在系统中完成采集模拟量(电压、电流等)和状态量(如开关状态) ,以及执行遥控(开、合操作)操作等功能。
If you have a source code control system installed on your computer that is compatible with visual web developer , you can use the source code control commands that are included with visual web developer to check files in and out of source control , merge files , view file history , and accomplish other source code control tasks with your web site 如果您的计算机上安装了与visual web developer兼容的源代码管理系统,则可以使用visual web developer中包含的源代码管理命令将文件签入源代码管理和从源代码管理中签出文件合并文件查看文件历史记录以及对您的网站完成其他源代码管理任务。
This text summarises several control forms of gushing out oil pump test platform simply , and mainly proposes analog and digital control schemes of close ring adjusting speed , at the same time , gives the principles and implementation methods used in parameters control and measuring , this text introduces the asynchronous electromotor " s control process , in which , fuzzy control arithmetic is used , and the control commands are passed on by means of communication between mcu and frequency converter . there are two parts in this system . one is superior computer that is ordinary pc , the other is hypogynous at89c52 . the functions of superior pc are control and display information through screen , and the functions of ats9c52 includes control , collecting , display , treatment , uploading of all parameters 详细介绍了应用模糊控制算法,以变频器通讯方式进行异步电机调速的控制过程。系统由上位机和下位机两部分组成。上位机为普通pc机,主要实现系统控制、数据显示等功能,另外还有数据库浏览、数据打印等功能;下位机以at89c52为核心,负责所有参数的采集、处理、显示、上传、控制等。
