Network Structure and Transmission Protocol for Transformer Collection

With the transformers heavy using, efficient and reliable network and transportation protocol are becoming more and more important to collect energy data from the transformers. This paper proposed a new network topology for data collection from large amount resident transformers. This topology could provide flexible access service to user and improve network scalability. This paper also proposed a new data transferring protocol based on SNMP. The messages are classified into three types and encapsulated into trap packets. With an add-on acknowledgement mechanism, the new protocol could guarantee the delivery of important messages and merge other messages. It improved the utilization of the data collection network.
