摘　　要：为了让操作者可以通过浏览器维护和管理监测点,方便其查看监测数据,设计利用BOA服务器搭建嵌入式Web控制器、传输层选择有三次握手和超时重传机制的TCP并包含了针对数据发送的防丢失措施。采用AJAX技术实现环境参数异步传输,以JSON格式作为数据交互格式,用CGI实现客户端与服务器端的请求和响应,Shell脚本实现CGI程序动态访问、自动更新环境参数。In order to enable the operator to maintain and manage the monitoring points through the browser,so as to facilitate the operator to view the monitoring data,the BOA server is used to build the embedded Web controller,the TCP with three handshakes and timeout retransmission mechanism is selected in the transport layer,and the anti-loss measures for data transmission are included.AJAX technology is used to realize asynchronous transmission of environment parameters.JSON format is used as data exchange format.CGI is used to realize client-side and server-side request and response.Shell script is used to realize CGI program dynamic access and automatic update of environment parameters.
