摘　　要：为了解决传统B/S结构实时监控系统在线运行期间存在网络负载大、服务器开销大、客户端与服务器之间的交互效率低的弊端,提出了用Ajax特有异步通讯的方式与CGI进行下位机通信、与SVG相结合进行矢量图形实时显示的方法来实现煤矿井下排水系统的在线实时监测。实验证明,这种方法不仅可以减轻服务器的负载而且可以节省网络带宽,网页页面显示无刷新,曲线图可以自由放大缩小不失真、跨平台,是满足系统要求的一种高效而简便的方法。In order to improve the problems of traditional real-time monitoring system, for example, high network load, low data exchange rate between client and server, high cost of server, asynchronism communication of Ajax to realize the communication method between upper computers and lower computers. Combine Ajax with SVG to achieve real-time monitoring of the mine drainage system. Practice has proved that this method not only can reduce the server＇s load can reduce network bandwidth, web page showed no update, you can free to decrease or increase the curve size, cross-platform, which is a high effective and simple way.
