The cryptographic hash will be broadcast to the nodes over the blockchain network. The power secondary equipment verifies the login access of the operation and maintenance personnel through the configured AAA service block chain node.

In the service, data on the chain is further subjected to data aggregation, a log database under the chain is constructed, the process tracing based on the operation log is realized, and basic support is provided for compliance verification.
The Emitter plug-in provides a data cooperation mode, and actively pushes messages on a chain to the plug-in, so that events and data on the chain output by the plug-in are connected by a JavaScript language. The user can monitor the corresponding slot according to the requirement to obtain the preprocessed block data. The user can select any mode to consume the obtained data, and the freedom is high. In the operation and maintenance system, data can be reprocessed and is durable, and data service capability is provided for the outside.
And the operation log of the operation and maintenance personnel is subjected to evidence storage and storage through a log data system of the block chain. Based on the characteristics of safety, credibility, traceability and the like of the block chain, the requirements on scenes such as operation log flow tracing, compliance verification and the like are also met.
And the operation and maintenance personnel push the operation command log to the remote AAA service system in real time through the configured address on the operation log of the power secondary equipment. The AAA service system is responsible for storing the operation log in an uplink way. Since the number of oplog entries can be very large, a memory-certified contract will only store them in the blockchain log system, not in the state table of the contract.
The block chain system is not suitable for directly processing the process tracing of the operation log, and the monitoring system stores the operation log data on the synchronous chain through the data cooperation module on the chain and the data cooperation module on the chain into a database on the chain for processing. In the down-link database, the logs can be collected and processed by common conventional development means, classified monitoring is carried out according to users and equipment, and meanwhile, operation processes can be backtracked according to time to check whether dangerous operation exists.
For the key operation and maintenance accidents, the monitoring system can issue a relevant operation log report, and all the operation logs can be inquired in the blockchain system, so that the truth and the reliability of the log report are ensured.
