Multimode communication gateway design in heterogeneous network environments intelligent distribution and utilization

Since large quantity and wide range of the monitoring objects, high concurrent of the business access, complication and changeability of the runtime environment, it is difficult to adopt a single communication transmission system and a single way of media access in the communication of smart distribution grid. It is existed as public network, private network, cable network and wireless network all at once. Researched and designed a network interconnection scheme, which can be used in the heterogeneous network of smart distribution gird. Through the analysis of actual demand about distribution gird, designed ad-hoc network solution based on XML description language. And used the design thought of IEC61850 protocol in heterogeneous network of distribution gird. By researching the process of transcoding, receiving, encoding and sending, formed a multimode communication gateway design scheme to support the interconnection of various heterogeneous communication networks. Through constructing a heterogeneous network test platform, completed the feasibility experiment of this gateway scheme.
