基于WEB和SVG的EAST真空监控和数据处理系统

The Design of EAST Vacuum Control System Based on Web and SVG

目前自动化领域的WEB组态通常在客户端嵌入J2EE/Applet实现C/S的回归,这种方法在很多方面都有极大优势,如安全性、移植性、动态性等,然而编程相对复杂。随着SVG(Scalable Vector Graphics)和AJAX(Asynchronous JavaScript And XML)被广泛地支持,允许我们在绝大多数的浏览器上实现矢量绘图和简单的C/S回归,实现类似于Applet的功能,如信息的异步传输、数据的图表显示和查询等。介绍一种通过SVG、AJAX、OPCXML-DA、COM等多种技术实现Web组态的功能。

the J2EE / Applet is usually embedded in the client to achieve the C/S regression of the web configuration in automatic field. This method has great advantages on many respects such as security, portability, dynamic and so on,, but programming is not easy. With SVG （Scalable Vector Graphics） and AJAX （Asynchronous JavaScript and XML） being widely supported, the vector plotting and simple C/S regression can be allowed in the vast majority of browsers. So the functions similar with Applet can be accomplished, e.g. information asynchronous transmission, data graph and search. It introduces a meth- od to achieve the web configuration by applying the techniques of SVG, AJAX, OPCXML-DA, and COM.
