基于Web的电力调度信息系统中图像存取方案研究

Research of Image Access Solutions in Power Dispatch and Management Information System Based on Web

为有效地处理电力调度信息系统中图像数据存取问题,提出将图像转换为二进制流存储于数据库中,将图像提交到W eb服务器的文件系统中,以及使用XML文档存储图像3种方案,并分析其各自的优缺点及适用场合.3种方案已经成功应用于江苏省电力调度信息系统等大型项目中,很好地满足了电力企业调度信息系统不同使用场景中对图像数据的存取要求.

In order to efficiently deal with image access in the power dispatch and management information system, three resolutions are offered, i.e. images are converted to binary stream and stored in a database, image files are submitted to file system in web server, and image data is stored in XML document. The advantages and disadvantages of the three so- lutions are also analyzed and their applied occasions are given. The three solutions have been successfully applied to sev- eral large-scale projects such as DMIS in Jiangsu Province, and varied image access requirements are satisfied.
