WEB煤矿联网监控系统,具有数据量大、实时性要求高等特点,所以要在数据处理方面进行性能优化,避免冗余数据的重复下载。传统的技术采用刷新整个web页面来更新页面的数据,这种方式存在2个缺陷,一是由于整个页面的刷新产生的闪烁效果给浏览者的直接感受不好;二是刷新整个页面,每次都要重复下载整个页面的数据,造成数据量大,显示延迟。采用AJAX技术,只用来更新需要实时显示的数据部分,从根本上解决了传统技术存在的缺陷。
WEB coal mine network monitoring system, with a large amount of data, real-time requirements of higher characteristic, so to optimize the performance of the data processing, to avoid duplication of redundant data download. Traditional techniques refresh the entire web page to update the page data, there are two defects in this way, one is due to the flash refresh effect of the entire page to the viewer’s direct feel bad; the second is to refresh the entire page, each time Have to download the entire page to repeat the data, resulting in a large amount of data, display delay. The use of AJAX technology, only used to update the need for real-time display part of the data, a fundamental solution to the shortcomings of the traditional technology.
