Description

Technical Field

[0001] This application relates to the technical field of general control or regulation systems, and particularly to a replacement method and system for replacing a control cabinet while it is partially energized. Background Art

[0002] With the improvement of industrial intelligence and automation levels, it has become increasingly important to maintain the continuous and uninterrupted status of telemetry and telemetry signals in the control cabinet. The function of the control cabinet in a hydropower station is to control the operation of the production equipment in the hydropower station. The telemetry and telemetry systems in the control cabinet pass through sensors and signal acquisition devices and transmit relevant data to the computer monitoring system. However, during the use of the control cabinet, due to reasons such as equipment aging and technological updates, the control cabinet needs to be renovated. Traditional methods for renovating control cabinets usually require power outage, disconnecting all the wiring in the old control cabinet, and connecting all the wiring as a whole to the new control cabinet. In some special scenarios, the renovation of the control cabinet cannot affect the normal power generation and production operations of the hydropower station. However, in the process of this traditional technology, due to the need to disconnect the power supply of the control cabinet, the transmission of telemetry and telemetry signals in the control cabinet is interrupted, resulting in the monitoring system being unable to normally monitor the relevant data. Summary of the Invention

[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0023] It should be noted that a blockchain can be defined as a continuously increasing list of blocks, where each block is linked to the hash value of the previous block. A block consists of transaction data, a timestamp, and the hash value of the previous block. A blockchain is a distributed ledger, where transactions are stored in the form of blocks and distributed in a P2P network (peer-to-peer network), and each node holds a copy of the ledger. Because a blockchain has high security and is almost impossible to be leaked, hash encryption and distributed ledger have more unique attributes compared with other technologies. An important feature of a blockchain is the transparency of information for each node or participant, and the information cannot be modified, thus reducing fraudulent data and tampered data, which helps to establish trust. A blockchain is customizable, and once the relevance conditions are met, operations can be triggered.

[0024] Hyperledger Fabric is an open-source blockchain framework aiming to provide efficient and scalable distributed ledger technology for enterprise-level applications. Hyperledger Fabric has a modular architecture, which contains multiple key modules that work together to provide an efficient, secure, and scalable enterprise-level blockchain platform. The main modules are Node, Ledger, Chaincode, and Consensus, etc.

[0025] Distributed storage in a blockchain means that each participating node has an independent and complete data storage. The uniqueness of the distributed storage of a blockchain is reflected in two aspects: one is that each node of the blockchain stores complete data according to the block-chain structure; the other is that each node storage of the blockchain is independent and of equal status, relying on the consensus mechanism to ensure the consistency of storage, and the data nodes can be different physical machines or different instances in the cloud.

[0026] Embodiment

[0027] Please refer to Figures 1-3 , an embodiment of the present application provides a replacement system for partially charged replacement of a control cabinet, which relates to the technical field of general control or regulation systems. The system includes a processor, and further includes: a construction personnel management module, a new cabinet position planning module, a KKS management module, an outage interval division module in the old cabinet, an old cabinet information collection module, a fuzzy wire number tracing module, a construction form generation module, and a construction risk warning module that are data-connected to the processor.

[0028] Furthermore, the construction personnel management module is used to create a digital identity and generate a digital tag corresponding to the displacement; the new cabinet position planning module is used to automatically obtain a reasonable position of the new cabinet according to local large model technology; the KKS management module is used to encode the original wire numbers according to the KKS code; the outage interval division module in the old cabinet is used to divide based on preset principles; the old cabinet information collection module is used to input all wire number heads in the old cabinet and all signal point description information in the human-machine interface into a distributed database; the fuzzy wire number tracing module is used to find the correct wire number when the wire number mark is fuzzy; the construction form generation module is used to generate a construction form; the construction risk warning module is used to give risk warnings for the renovated part.

[0029] It should be noted that the construction personnel management module is used to create a digital identity on the blockchain network through public and private key pairs, and generate a unique digital tag for each person according to different personnel roles and qualifications to ensure the uniqueness and verifiability of logged-in personnel. The new cabinet location planning module is used to automatically obtain the reasonable location of the new cabinet based on local large model technology. Constraints such as the distance requirements between the old and new cabinets and the load-bearing capacity of the cable tray are entered into the local large model to obtain the reasonable location of the new cabinet, ensuring that the cables of the old cabinet are connected to the new cabinet. When necessary, transfer terminals can be used to extend the cables. The KKS management module is used to encode the original wire numbers according to the KKS code. The power outage interval division module in the old cabinet is used to divide according to the principle of "not affecting production", preferably customized according to the requirements of the superior power dispatching, and all the equipment in the old control cabinet is divided into different interval equipment. The old cabinet information collection module is used to input all the wire number heads in the old cabinet and the description information of all signal points in the human-machine interface into the distributed database by combining intelligent image recognition and manual annotation. The fuzzy wire number traceability module is used to trace the data of this point in the distributed database by looking up the digital tag corresponding to the terminal number when the wire number mark is fuzzy, and finally find the correct wire number. The construction form generation module is used to generate a construction form, and the content of the construction form includes the cabinet numbers of the old and new cabinets, terminal block numbers, wire number heads, wire diameters, wire colors, signal point names, and remarks; the construction form can be output in the available format of the wire number printer for convenient printing of wire numbers. The construction risk reminder module is used to remind of the risks of the transformation parts with higher risks such as PT, CT, and synchronization terminals. The risk reminder rules can be customized by the construction personnel according to the site personalization. In the transformation process of traditional technologies, there will also be problems such as fuzzy wire numbers, personnel job mobility, making it difficult to find wiring changes, and inadequate process control, making it easy for personnel operations to make mistakes and increasing potential safety hazards during the transformation process. The replacement system for partially live replacing the control cabinet provided in this embodiment can realize data collection, intelligent recognition, wire number traceability, on-chain management of wiring construction, and risk reminder and early warning during the control cabinet transformation process, solve the problem in the prior art that it is impossible to normally monitor data due to a long power outage time, and at the same time solve the problems of fuzzy wire numbers, personnel job mobility, making it difficult to find wiring changes, and inadequate process control, making it easy for personnel operations to make mistakes and increasing potential safety hazards during the transformation process.

[0030] On the other hand, a replacement method for partially live replacing a control cabinet is provided, which at least includes:

[0031] Implement permission management and module construction for the KKS management module based on Hyperledger Fabric;

[0032] Obtain the location of the new cabinet based on the large model. After the target personnel confirm the location of the new cabinet, execute to call the chain code to encrypt and store the personnel digital tag and the location of the new cabinet to the blockchain;

[0033] After the power-on of the new control cabinet after the in-cabinet commissioning work on the target personnel is completed, execute the call chain code to encrypt the personnel digital tag and the completion time and store them in the blockchain;

[0034] Divide into n target intervals and number them 1 - n. Based on the different scheduling requirements of the target work responsible persons, formulate a power outage plan, and execute the call chain code to encrypt the personnel digital tag and the power outage plan and store them in the blockchain;

[0035] Based on the system engineer's completion of the touch screen photo collection and the old cabinet line number head photo collection, extract the line number information through image recognition technology. The target work responsible person marks the special line numbers, and the extracted line number information is automatically encoded and output through the KKS management module. Execute the call chain code to encrypt the final KKS code and the digital tags of the safety officer, wiring operator, and system engineer and store them in the blockchain;

[0036] Based on the large model to assist the safety officer to execute the formulation of risk warnings and safety measures according to the power outage plan;

[0037] Based on the collected pictures to make a construction table, execute the call chain code to encrypt the construction table details and the personnel digital tag and store them in the blockchain;

[0038] Number the equipment based on the target interval, and remove the signal cables of the numbered target interval in the old cabinet according to the construction drawings;

[0039] Print new line numbers and connect the cables of the numbered target interval to the new cabinet;

[0040] Based on the power outage plan, complete the cable migration of n target intervals.

[0041] Specifically, in this embodiment, on the premise that not all 6 intervals are powered off, the transformation of the LCU control cabinet is realized, and the implementation steps are as follows:

[0042] Step 1, use Hyperledger Fabric to implement permission management and module construction, enter personnel information in the KKS management module, assign roles, and generate personnel digital tags: work responsible person, safety officer, wiring operator, system engineer.

[0043] Step 2, conduct on-site surveys of the specific location of the old cabinet and the approximate location of the new cabinet, enter the constraint conditions such as the distance of the old cabinet and the load-bearing capacity of the cable tray into the Peer node of the Hyperledger. After obtaining the new cabinet location through the large model, and after this location is confirmed by the personnel, execute the call chain code to encrypt the personnel digital tag and the specific location of the new cabinet and store them in the blockchain.

[0044] Step 3: Power on the newly installed control cabinet. After the engineer completes the in-cabinet debugging work, call the chain code to encrypt the personnel digital tag and the completion time and store them in the blockchain.

[0045] Step 4: Divide the 6 intervals into 6 parts and number them 1 - 6. The person in charge of the work formulates a power outage plan according to different dispatching requirements without affecting the business, and calls the chain code to encrypt the personnel digital tag and the power outage plan and store them in the blockchain.

[0046] Step 5: The system engineer completes the collection of touch screen photos and the collection of old cabinet line number head photos, extracts the line number information through image recognition technology, and the person in charge of the work marks the special line numbers. All line numbers are output through KKS automatic coding. Call the chain code to encrypt the final KKS coding and the digital tags of the safety officer, wiring operator, and system engineer and store them in the blockchain.

[0047] Step 6: Use the local large model to assist the safety officer to formulate risk warnings and corresponding safety measures according to the power outage plan.

[0048] Step 7: Make a construction table based on the collected pictures. The construction table includes the cabinet numbers, terminal block numbers, line number heads, wire diameters, wire colors, and signal point names in the new and old cabinets. Encrypt the details of the construction table and the personnel digital tag through the chain code and store them in the blockchain.

[0049] Step 8: Take the equipment transformation of interval K with a number as an example. When the equipment in interval K with a number is powered off, the construction personnel read the current risk warning and take safety measures. The wiring operator removes the signal cable of interval K with a number in the old cabinet according to the construction drawing, keeps the old line number on the wire, and uses insulating materials to protect the line number head.

[0050] Step 9: Print new line numbers, connect the cables of interval K with a number to the new cabinet. When it is difficult to connect the wires due to the loss of old line numbers, unclear line numbers, etc., the Membership Service Provider can be used to log in to the browsing permission and check by viewing the previous photos. After the connection is completed, the remote signaling and remote measurement of interval K with a number can be seen in the monitoring background, and then the power supply of interval K with a number can be restored.

[0051] Step 10: Complete the cable migration of the 6 intervals according to the power outage plan, and then complete all the transformation work of the control cabinet.

[0052] Step 11: Calculate the performance of each role according to the workload and quality of the content on the chain.

[0053] Compared with the traditional method of transforming a control cabinet that requires the entire power outage of the control cabinet, the present invention only needs to temporarily cut off the power supply of some intervals of the control cabinet to complete the transformation of the control cabinet. The blockchain technology is used to store data such as wire numbers, ensuring the reliability of the data, and helping to improve the efficiency and quality of the transformation work of the hydropower station control cabinet.

[0054] It should be noted that the switchyard includes 1 set of new local control units (LCUs for short) and 1 set of old LCUs, and the on-site equipment involves the disconnector information of 6 intervals. The human-machine interface device in the LCU cabinet is used to monitor and control the main monitoring screen of the switchyard, including the remote signaling and telemetry signal points of all intervals in the switchyard. There are several PLC modules in the LCU to collect the remote signaling and telemetry data of 6 intervals on site and send them to the monitoring background.

[0055] It should be noted that compared with the traditional method of transforming a control cabinet that requires the entire power outage of the control cabinet, this embodiment only needs to temporarily cut off the power supply of some intervals of the control cabinet to complete the transformation of the control cabinet. The blockchain technology is used to store data such as wire numbers, ensuring the reliability of the data, reducing the power outage time of the hydropower station, improving production efficiency, reducing production losses, and helping to improve the efficiency and quality of the transformation work of the hydropower station control cabinet. In addition, the method provided in this embodiment can complete the transformation of the control cabinet under the condition of interrupting some remote signaling and telemetry for a short time; the method provided in this embodiment uses image recognition technology for wire number transcription and stores the original panel wire numbers in a distributed database; the method provided in this embodiment uses automatic KKS coding technology to solve problems such as missing wire numbers and non-standard temporary numbers; the method provided in this embodiment uses blockchain and distributed storage technologies to store KKS codes and digital tags of on-site construction personnel, realizing traceability of wire number changes and data anti-tampering; the effective records of on-site construction personnel modifying wire numbers provided in this embodiment can be used as the scope of personnel performance evaluation to prepare for the future expansion of this blockchain; when the transformation process involves changes in important cables, the large language model trained by the power system prompts risk warnings to remind construction personnel of the current safety measures.

[0056] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
