摘要
针对当前实验室普遍出现实验场地或新设备不够的问题,总结和借鉴了国内外网络实验室的现状和经验,提出并实现了一种以S7-300可编程逻辑控制器作为基本控制装置,以OPC作为软硬件通讯接口,以Profibus现场总线、工业以太网和Internet作为通讯枢纽,并利用Java Applet,JavaScript,JSP等交互式动态页面技术实现友好实验平台的远程实验室系统.最后以远程控制过程液位对象为例,通过登陆友好的远程控制实验室系统,成功地实现了对实验装置的控制,证明了该远程实验室系统的可行性.
Now lacking of lab space or new equipments in the lab are becoming a widespread problem. Summarizing and referring the networked laboratories home and abroad, the remote laboratory system which is based on S7-300 PLC controller is brought forward and realized. The OPC as its communication ＂interface, and Profibus, industrial Ethernet and Internet as its communication ways are used in this system. The human-machine interface is developed using Java Applet, JavaScript, JSP and so on, which are dynamic Web technologies. A case of remote level control of the pilot tank is described. Through logging in the remote laboratory system friendly, the experimental equipments are controlled successfully. The feasibility of this system is proved.
