摘　　要：针对医院档案信息数据提取复杂度高的问题,本研究将医院的档案信息分为文字信息和数字信息,提出了一套基于云计算环境下的档案信息管理系统,利用线性归一化和非线性归一化对文字信息进行去噪预处理,结合外边框和质心归一化进行文字信息的数据提取;针对字符信息利用点阵图和字符轮廓平滑处理,将字符的轮廓获取和存储进行特征值提取。通过设计医院档案信息的容器编码,并结合分布式关联数据库以供信息的汇总和共享,方便了系统管理员对档案信息的综合调度使用。在对医院档案信息数据提取实验测试,结果显示:初步识别提取率与综合数据提取率均分别保持在90%和80%以上,并且云计算数据提取效率明显高于电子标签(RFID)数据提取。For the problem of hospital records information data extraction of high complexity, the study will be divided into text files hospital information and digital information, a set of file-based information management system for cloud computing environment, the use of linear and non-linear normalization normalization of text messages denoising pretreatment, combined with external borders and the centroid of the normalized data for text information extraction; smoothing process for the use of bitmap character information and character outline, the outline of the character is captured and stored eigenvalue extract. Hospital records through the container code design information, combined with the distributed relational extraction rates were maintained at above 90% and 80%, and cloud computing data extraction efficiency significantly higher than the electronic tags （RFID） data extraction.
