In this scheme , ethernet is applied to infranet , and opc technology is used to data acquisition from local control unit . socket communication and java applet technology are used to realize real - time data exchange . according to the design project of hydro power remote monitoring and control system , a remote monitoring experiment system is designed in this thesis 论文以水电站自动化改造项目为背景,设计了中小型水电站的远程监控系统,提出了基于web的中小型水电站远程监控系统的具体硬件结构方案和软件的整体设计思路,控制网络采用工业以太网,实现了控制网络与信息网络的融合,应用opc技术进行数据采集,使用javaapplet和socket通信技术解决远程实时通信问题。
By using equable mesh refinement techniques and effectively handling the holes in the gray - image , the car ’ s shape can be exactly reflected 。 second , shape design with vrml and deforming methods of 3d - model based on image is discussed 。 by using warp techniques based on profile of the model , we can easily remesh so as to implement the shape customization 。 finally , entire customization system is discussed and communication mechanism between java applet and servlet and some related technology of jdbc database are analyzed 。 interactive methods in the customization system are introduced to modify appearance and parameter of person - machine effects of the product 。 本文采用基于特征轮廓线的深度图像变形,重建新的三维模型,实现外形的定制。最后,分析了编程中的javaapplet与servlet通讯机制、数据库等关键技术,对整个定制系统构成进行阐述。介绍了定制系统中的交互机制,及定制模块包括外观、外形、人机工程、运动控制等来实现产品的个性化定制。
Of course , the theories and approaches about the design of database management system and how to integrate our previous research results into the fpax ' s system will be discussed as a main point . part two : in this part , we attempt to introduce the model of the web site so as to build a teleconsultation system based on the browser / server model . via using the java language program , we hope that our telemedicine user can achieve the goal of the teleconsultation just using a www browser 本研究试图对应用java技术构筑远程医疗网进行一点初浅的探讨,希望借助java的强大功能,应用jsp / servlet建立一个远程医疗网站;应用javaapplet实现电子白板、语音传输、文字交流等功能;采用jpeg和小波算法实现图像的压缩;实现多种传输模式结构;实现病历数据的后台管理;最终建立一个适合不同操作系统的远程医疗会诊及教育系统。
Server side content pushing is somehow difficult in a b / s application since most of the time a transaction is customer ( brower ) initiated . but it is required in our inspection platform . a certain means of server side pushing technology was discussed and implemented in this paper , which using a multi - thread service application to receive the client ' s socket connection request in the server side and using javaapplet , javascript - frame communications and dynamic web page refreshing technologies in the customer ( browser ) side 在监测平台中,需要将服务器端内容向客户端主动传送,而在b s模式下,总是客户端(浏览器)主动发出请求,服务器才对请求作出反应并传送内容,本文通过在服务器端采用一个多线程的接受客户端socket连接请求的网络应用服务,在客户端采用javaapplet 、 javascript帧间通信、 dhtml动态更新页面等技术,设计并实现了服务器端内容的主动推送,并在客户端实时显示。
