跨网传输的实时试验指挥显示系统设计

Design of Real Time Task Data Command and Display System Based on Cross Network Transmission

根据测控任务的特点,设计了一种基于跨网传输的B/S模式的试验信息实时指挥显示系统,详细阐述了基于跨网数据传输的串口通信方法,解决了不同局域网之间数据通信的安全性和可靠性,通过Ajax技术和服务器端两级数据缓存技术应用,减少数据流量和服务器负荷,解决了试验任务信息的高实时性、无屏闪、局部刷新的浏览器页面的数据、曲线实时显示等关键技术,并对提出的架构和方法进行了系统验证。

According to the characteristics of the maritime tracking and control missions, a kind of task data real time command and display system, brower/server model based on the cross network trans- mission, is designed. Firstly, the serial port data communication method based on across a network data transmission is introduced. It settles the security and reliability of data communication. Secondly, the Ajax technology and server two layers data caches technology reduces the data flow of the internet and server load, and some key technology are resolved, such as the high real time of data display, data and curve display way of local refresh and so on. Finally, the system architecture and realization method are tested and verified.
