基于工业组态软件的远程PLC虚拟控制系统的研究
|
摘要
计算机网络技术和通讯技术的发展,远程控制已经成为当今自动化领域的一项关键技术,越来越受到重视。目前基于工业组态软件的远程PLC虚拟控制系统在教学上尚无具体的应用。在各学校的电气系和机械系的相关专业中,均开设了相关课程、实验、课程设计、毕业设计等教学环节。购置足够用于实验和各种环节的设备,需要相当高的资金投入,而且大多数只有控制层,难以开设出具有灵活性、创新性和综合性的现代特色实验。为了节约资金,提高教学水平与科研水平,我们决定研究一种基于工业组态软件的远程可编程控制器虚拟控制系统,利用现有的计算机资源,在计算机上通过组态软件的工作界面和功能来进行远程PLC的虚拟控制,使学生可以利用它达到PLC设备与现场设备通信的实践教学效果。同时在实际工业控制系统中用PLC与现场设备相连便可以实现实际的远程控制。这一课题的研发对工业控制领域有极强的现实意义。
基于工业组态软件的远程PLC虚拟控制系统的研究首先是进行PLC和上位机之间的通信,然后把采集的数据进行归档,并完成实时和历史数据处理、报警和安全机制、流程控制、动画显示、趋势曲线和报表输出等系列工作。然后通过服务器把已有的组态工程发布到网上,局域网上的计算机用户输入IP就可以通过IE浏览器访问运行了MCGS WWW网络版工程的计算机,并方便的浏览到工程中的组态画面,查看现场实时数据和历史数据并对其实行监控。本课题还阐述了基于RS-485网络的虚拟控制系统,即PC与多台PLC通信组成的1:N网络监控的系统,介绍了其结构以及工作原理,并且详细说明了485网络组建技术。本课题还介绍了基于MCGS组态软件的其他设备的远程虚拟控制系统
With the development of the computer network technology and the communication technology, the remote control has already become an essential technology in automation domain now, and has received more and more attention. At present, remote PLC Virtual control system based on industry configuration software still has not concrete application in teaching. Relative specialty of the electric department and the mechanical department of many schools, have correlative curriculums, experiments, curriculum design, graduation project and so on. If enough experiment equipments are purchased, very high fund will be needed, moreover majority equipments only have the control level, it's difficult to start flexible, innovative and comprehensive modern characteristic experiments. In order to save the fund, improve teaching level and science research level, we decide to research a kind of remote PLC Virtual control system based on the industry configuration software, utilize existing computer resources, make remote PLC Virtual control through the working interface and the function of the configuration software on the computer, then students can reach the experiment aim of communication between PLC and the scene equipment. At the same time, connecting PLC with the scene equipment in actual industry control system, it can realize the actual remote control. This topic research has greatly practical significance for the industry control domain.Remote PLC Virtual control system research based on industry configuration
software, at first, completes the communication between PLC and PC, then classifies the gathering data, and completes series work such as processing real-time and historical data, giving an alarm and safety mechanism, flow control, motion picture demonstration, trend curve and report form output and so on, at last issues the configuration project on the web through the server, remote computer users can browse the computer on which the project is running on MCGS WWW network version by IE, and browse the configuration pictures of the project conveniently, examine on-site real-time data and historical data and monitor and control this project at the same time. This topic discusses the virtual control system based on 485 networks, namely a 1: N network monitor and control system of communication between PC and a few of programmable controllers. This topic introduces its structure and working principle, and describes how to establish 485 networks in detail. Furthermore remote virtual control system of other devices based on the MCGS configuration software is introduced, including the design of virtual control system of the device that has driver or not. The second status is mainly elaborated. It has two ways, the first one is to develop the driver of the communication between intelligent instrument based on Single-chip and MCGS on the platform of MCGS, and to explore the drive connect method between common intelligent equipments and configuration software. The second one is to communicate indirectly through DDE "soft channel". Furthermore the network of virtual control system of other devices based on MCGS is introduced, and the realization of the network control function of other devices' virtual control system.
