基于SOAP/REST混合式SOA的输变电设备信息集成平台

Transmission and transformation equipment data integration platform with mixed SOA based on SOAP/REST

针对电力系统中存在的多源、异构信息汇聚、融合及全景应用困难的问题,提出了一种基于混合式SOA的解决方案。设计了混合使用SOAP/WSDL和REST两种不同实现技术、综合SOAP/WSDL机制完善和REST简洁高效两种优势的面向服务构架,并分析阐述了电力系统中的多种源数据的提取方法、CIM等关键数据格式的解析方法、SOAP/WSDL服务和REST服务的实现与封装方法等。搭建了一个输变电设备全景信息集成平台,对需要使用的一些关键技术进行了技术研究与验证。该平台中,将数据集成业务封装为REST服务,再与其他上层SOAP/WSDL服务相配合,共同发布到企业服务总线上完成了流程编排,从而完成了相应功能。研究结果表明,由于混合使用了两种不同的SOA实现技术并能按需对服务进行替换或编排,业务功能实现上具有高效、灵活的优势。

Aiming at the knottiness of panoramic application, which is caused by the difficulty of gathering heterogeneous information from multi-source in power system and the information integration, a new kind of service based architecture was designed and applied, with SOAP/WSDL and REST mixed and each other complemented. Method of data extraction from a variety of sources, key data format parse and realization of service-oriented architecture with mixed manners were discussed. A validation platform was established to research and test the key technologies to be used, on which data integration application was encapsulated as REST service and other upper applications SOAP/WSDL services. The services were orchestrated on the enterprise service bus, thus completing the corresponding function. The result indicate that it is of flexibility and hi~,her efficiency to use different SOA implementation technologies.
