HL7消息解析、传输与格式转换技术研究与实现

Research and implementation of HL7 message parsing, transmitting and format converting technology

为实现符合HL7标准的医学信息的解析、网络传输,以及ER7格式与XML格式的转换,将HL7信息解析成为"Message"抽象数据结构实现解析;通过构建符合HL7标准的客户端和服务器实现HL7的传输通信;通过先将ER7/XML格式的HL7信息解析为"Message"数据类型,再构建成另外一种信息格式(XML/ER7),实现两种格式的互相转换。实现了HL7解析、传输与格式转换功能,并用Messaging Workbench对消息传输进行了测试验证,证明构造的客户端和服务器能够相互通信并符合HL7标准。HL7信息解析、传输是众多医疗信息系统的核心功能,对解决"信息孤岛"问题是大有裨益的。

For medical information of HL7 standard to realize the parsing, transmission and format conversion between ER7 and XML, HL7 messages is parsed to ＂Message＂ abstract data structure; HL7 client and HL7 server is constructed and a two step converting method is used. The functions of parsing, transmission and format conversion are realized in this paper, and the message transmission function is tested and verified by Messaging Workbench. The constructed client and server are proved to be able to communicate each other, and to meet the HL7 standard. HL7 information parsing and transmission are the core function of many medical information systems, which is helpful to solve the ＂information island＂ problem.
