(1) The central control system is used for collecting the state information of all the subsystems and equipment in the transformer substation, and is also used for scheduling the working states of all the subsystems and equipment in the transformer substation.
The central control system is installed in a server in a central control room, and the central control systems of different substations realize information sharing through a blockchain, because the blockchain has high security (the blockchain adopts a decentralized distributed recording mode, each node in the system simultaneously participates in data change recording, each node keeps an identical and complete data sample, a single node is destroyed and cannot influence the integrity of the whole sample and the record, the security of the data is greatly improved), high transparency (a public blockchain system is open, all nodes with maintenance function are commonly maintained, except that private information of each transaction party is encrypted, any person can inquire the blockchain data and develop related applications through a public interface, so that the information of the whole system is highly transparent), and high autonomy (the blockchain adopts a standard and a protocol (such as a set algorithm) based on negotiation consistency), the method has the advantages that each participant can freely and safely transact in an environment without trusting any person, the trust of people in the past is changed into the trust of machine algorithm, the elimination of man-made interference factors is highly autonomous), and the property of non-tampering (once the information is verified and added to a block chain, the information is permanently stored, a data record which is marked according to the time sequence and is difficult to tamper is generated, the traceability of data can be ensured, and the condition that different node data at different time points are counterfeited can be greatly reduced).
(2) The video monitoring subsystem is installed in the central control system in an embedded mode and comprises cameras installed at all point positions in the transformer substation and a first display screen arranged in the central control room, and the first display screen displays pictures shot by the cameras in real time.
