Application to intelligent distribution network data acquisition service bus system and its implementation method

Abstract

The invention relates to a bus system in the field of power systems and an implementation method thereof, in particular to a data collection service bus system applied to an intelligent distribution network and an implementation method thereof. At the data collection site, install multiple data collection terminals and one or more bus concentrators. The bus concentrator will cache the data messages of the connected collection terminals in real time, and perform data processing at the unified data collection service bus master station. When calling for testing, the cached collected data is encapsulated and uploaded; on the bus master side, after receiving the encapsulated message from the concentrator, the bus system unpacks it and performs protocol identification and analysis for storage. The proposal of the present invention can ensure the real-time performance of received data, improve the reliability of data collection, and can support the simultaneous access of multiple collection terminals with different protocols.

Description

technical field [0001] The invention relates to a bus system in the field of power systems and an implementation method thereof, in particular to a data collection service bus system applied to an intelligent distribution network and an implementation method thereof. Background technique [0002] At present, data acquisition services are widely used in power systems, and data acquisition technology has become more and more mature, but there are still some problems. [0003] On the one hand, the existing data collection generally uses the master station to call for measurement at regular intervals or the collection terminal to actively send it, which is the direct interaction between the master station and each collection terminal. However, due to the complexity of the on-site environment, it is easy to cause communication problems. Delays or interruptions that affect the reliability of data collection. [0004] On the other hand, when data is collected, the transmission of ...

Problems solved by technology

[0003] On the one hand, the existing data collection generally adopts the regular call-up of the main station or the active sending of the collection terminal, which is the direct interaction between the main station and each collection terminal. However, due to the complexity of the on-site environment, it is easy to cause communication problems. Delays or interruptions that affect the reliability of data collection

[0004] On the other hand, when data is collected, the transmission of the message must follow certain communication protocols, and due to technical or profit reasons, the communication protocols of different collection terminal manufacturers cannot be unified for the time being.

Therefore, in the actual collection process, due to the limitations of the communication protocol, the restriction on the selection of the collection terminal and the difficulty in analyzing the messages of the master station system during the implementation process increase
