Description

Technical Field

[0001] The present invention belongs to the field of information communication technology of distribution network, and relates to a communication networking method, in particular to a multi-station multi-fusion terminal point-to-point decentralized communication networking method. Background Art

[0002] The regional communication in the existing distribution substation area is mainly based on power line narrowband carrier and micro-power wireless. Optical fiber communication can also be used in urban communities where individual conditions permit. At present, the communication in the distribution substation area can meet the needs of centralized meter reading, but there are still problems such as low reliability and slow speed. In order to ensure the coordinated dispatch of flexible resources in multiple substations, its communication system needs to meet the conditions of high reliability, real-time, security and bidirectionality. The existing substation intelligent fusion terminal equipment uses the above-mentioned communication medium form to support three communication protocols: remote horizontal communication between substations, local communication with edge computing gateways, and communication between terminals and functional modules. The communication between substations generally adopts the form of power line carrier and multicast communication mode to interact with fixed substation groups. Among them, the communication distance of power line carrier communication is based on the communication power allowed by the specific power line, while optical fiber communication can support cross-city communication up to hundreds of kilometers. However, with the access of distribution substations to flexible resources such as distributed energy storage and electric vehicles, the traditional multi-substation communication system model can no longer meet the current business needs of the substation.

[0003] The existing fusion terminal collects the data collected by the substation equipment, performs preliminary processing, and then sends it to the master station of the platform layer. The cloud master station stores the data and provides the data to the application layer. It is essentially a centralized communication method. All substation data will eventually be summarized and stored in the cloud master station. The master station is the core of the entire system. However, due to the different characteristics of flexible resources in different substations, the amount of information transmitted between substations is increasing, and it is difficult to meet the realization of system functions by relying on the centralized communication method of the master station. In the existing distribution substation communication systems at home and abroad, there is little research on the deployment of point-to-point interactive communication, which cannot meet the requirements of reliability, timeliness, and bidirectionality.

[0004] Therefore, in order to solve the above problems, the present invention proposes a multi-station multi-fusion terminal point-to-point decentralized communication networking method.

[0005] After searching, no public documents of the prior art identical or similar to the present invention were found. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and propose a multi-station multi-fusion terminal point-to-point decentralized communication networking method, which can effectively solve the scalability and security problems of the traditional centralized architecture and support different types of terminal devices to access the network in a plug-and-play manner.

[0007] The present invention solves the practical problem by adopting the following technical solutions:

[0008] A multi-station multi-fusion terminal point-to-point decentralized communication networking method, comprising the following steps:

[0009] S1. Analyze the communication protocols of peer-to-peer communication of different converged terminals, and establish a point-to-point communication channel based on this;

[0010] S2. Based on the software and hardware decoupling mode of the converged terminal, the plug-and-play of the converged terminal is supported through the embedded APP on the hardware;

[0011] S3. Combine the point-to-point communication channel of step S1 and the plug-and-play fusion terminal of step S2 to form a flexibly expandable multi-station multi-fusion terminal point-to-point decentralized communication network.

[0012] Moreover, the specific steps of step S1 include:

[0013] (1) Analyze the end-to-end communication protocol between terminals in different areas. The message interaction based on the MQTT protocol includes the message interaction between micro-applications and data centers and between micro-applications.

[0014] (2) Establish communication channels between decentralized multi-convergence terminals, and each micro-application writes a message interface according to established rules to achieve orderly interaction between micro-applications and between micro-applications and data centers;

[0015] This enables point-to-point localized communication deployment and completes the establishment of point-to-point communication channels.

[0016] Moreover, the specific steps of step S2 include:

[0017] (1) Research the software and hardware decoupling mode of converged terminals, support the access of multiple different types of terminal devices, and manage the terminals through intelligent auxiliary control nodes;

[0018] (2) Through the embedded APP on the hardware, the terminal is guaranteed to have end-to-end communication and broadcasting functions;

[0019] (3) The terminal device accesses the network through the intelligent auxiliary control node and performs network access and data exchange according to different protocol types, thereby realizing plug-and-play of the converged terminal.

[0020] Moreover, the specific steps of step S3 include:

[0021] (1) Combining the point-to-point communication channel in step S1 and the plug-and-play converged terminal in step S2, and integrating them into the interactive architecture of decentralized multi-converged terminals;

[0022] (2) The system uses the decentralized and tamper-proof characteristics of blockchain technology to achieve terminal identity authentication, data encryption transmission and consensus verification, and obtain a decentralized communication network;

[0023] This will enable a flexible and scalable multi-area, multi-integrated terminal point-to-point decentralized communication network.

[0024] Advantages and beneficial effects of the present invention:

[0031] A multi-station multi-fusion terminal point-to-point decentralized communication networking method, comprising the following steps:

[0032] S1. Analyze the communication protocols of peer-to-peer communication of different converged terminals, and establish a point-to-point communication channel based on this;

[0033] The specific steps of step S1 include:

[0034] (1) Analyze the end-to-end communication protocol between terminals in different areas. The message interaction based on the MQTT protocol includes the message interaction between micro-applications and data centers and between micro-applications.

[0040] (2) Through the embedded APP on the hardware, the terminal is guaranteed to have end-to-end communication and broadcasting functions;

[0041] (3) The terminal device accesses the network through the intelligent auxiliary control node and performs network access and data exchange according to different protocol types, thereby realizing plug-and-play of the converged terminal.

[0042] S3. Combine the point-to-point communication channel of step S1 and the plug-and-play fusion terminal of step S2 to form a flexibly expandable multi-station multi-fusion terminal point-to-point decentralized communication network.

[0043] The specific steps of step S3 include:

[0044] (1) Combining the point-to-point communication channel in step S1 and the plug-and-play converged terminal in step S2, and integrating them into the interactive architecture of decentralized multi-converged terminals;

[0045] (2) The system uses the decentralized and tamper-proof characteristics of blockchain technology to achieve terminal identity authentication, data encryption transmission and consensus verification, and obtain a decentralized communication network;

[0046] This will enable a flexible and scalable multi-area, multi-integrated terminal point-to-point decentralized communication network.

[0047] In this embodiment, the multi-station multi-fusion terminal point-to-point decentralized communication networking method of the present invention supports plug-and-play and flexible expansion, and is matched with the centralized interaction architecture to achieve the complementary mechanism of "end-to-end" collaboration and "edge-to-cloud" collaboration and "edge-to-end" intercommunication, and supports the distributed collaborative optimization scheduling of flexible resources in multiple stations for the optimal decomposition of distribution network voltage reactive power control and demand response instructions. The design ideas of the localized communication deployment configuration method for point-to-point interaction in multiple stations are as follows: Figure 1 shown.

[0048] In this embodiment, the method of the present invention supports the integrated access of terminals in multiple areas, and can flexibly expand new terminal nodes, supporting the access and information exchange of multiple terminal devices.

[0049] In this embodiment, the method of the present invention studies the end-to-end communication protocol between terminals in different areas, establishes communication channels between decentralized multi-fusion terminals, and thus realizes point-to-point localized communication deployment; studies the software and hardware decoupling mode of the fusion terminal, and ensures that the terminal has end-to-end communication and broadcasting functions through the embedded APP on the hardware, thereby realizing the plug-and-play of the fusion terminal, and integrating it into the interactive architecture of the decentralized multi-fusion terminal to obtain a decentralized communication network.

[0050] In this embodiment, the implementation principles of the method of the present invention include the following four points: (1) Decentralized architecture: The central server is removed through blockchain technology, and all terminals are interconnected through a point-to-point network. (2) Plug and Play: Supports plug and play of terminal devices, and the device can automatically identify and join the network after access. (3) Flexible expansion: The system supports dynamic access and exit of terminals without affecting the stability and security of the existing network structure. (4) Multi-integrated terminal access: Supports the access of multiple different types of terminal devices (such as sensors, smart meters, robots, etc.), and manages the terminals through intelligent auxiliary control nodes.

[0051] In this embodiment, the method of the present invention adopts a decentralized network structure with blockchain as the core, and each node in the network has independent computing and communication capabilities. The nodes are divided into the following categories: (1) Micro-power sensors: mainly used for low-power, small-data-volume devices, such as temperature and humidity sensors. (2) Low-power sensors: used for devices with continuous data transmission requirements, such as transformer leakage current sensors. (3) Wired sensors: support the access of traditional wired devices, and access the wireless network through aggregation nodes. (4) Intelligent auxiliary sensors: support the access of broadband network-based devices such as cameras and robots.

[0052] In this embodiment, after accessing the network, each node in the present invention uses a point-to-point communication protocol to communicate directly with surrounding nodes, and records communication data through blockchain technology to ensure data security and integrity. The terminal device accesses the network through the intelligent auxiliary control node, and performs network access and data exchange according to different protocol types. The device can access the network through wireless, low-power wireless, wired, etc., to achieve diversified terminal device management. The schematic diagram of the communication networking method is shown in Figure 2 shown.

[0053] In this embodiment, the present invention utilizes the decentralization and tamper-proof characteristics of blockchain technology to achieve terminal identity authentication, data encryption transmission and consensus verification. Through distributed ledger technology, it is ensured that the communication data of each node is recorded and shared with all nodes in the network, thereby improving the security and transparency of the system. In order to support plug-and-play, the present invention designs a dynamic node discovery and adaptive network access mechanism. When a new device is connected, the system automatically assigns it a node identifier and generates a key pair. The new device quickly joins the network by establishing point-to-point communication with existing network nodes. At the same time, the aggregation nodes in the network will automatically update the network topology to ensure the connectivity of the system. The system design supports dynamic access and exit of terminals. When a new node joins, other nodes share the new node information through a point-to-point communication mechanism, and record the identity and access data of the new node through the blockchain. When a node exits, the network automatically adjusts the communication path between nodes to ensure data continuity and system stability. The specific blockchain algorithm design diagram is shown in the figure below. Figure 3 shown.

[0054] In this embodiment, the present invention can effectively solve the scalability and security problems of the traditional centralized architecture. By introducing blockchain technology, the system has a high degree of flexibility, security and scalability, and can support different types of terminal devices to access the network in a plug-and-play manner, providing reliable technical support for the development of the future power Internet of Things.

[0055] In this embodiment, the peer-to-peer communication system architecture of the present invention is as follows: Figure 4 As shown, the system communicates upward through the IEC104 protocol to realize the master station general call, remote signal change upload, and telemetry change upload functions; the MQTT protocol is used to obtain the real-time data of the primary equipment connected to the fusion terminal, including the distribution room, flexible interconnection equipment, branch box, photovoltaic, etc.; the horizontal communication between fusion terminals is also based on the MQTT protocol. The system supports peer-to-peer communication of up to 10 devices. When the data of this device changes, the system will publish the changed data through MQTT, and other fusion terminals will receive the changed data and output it at the terminal.

[0056] The working principle of the present invention is:

[0057] The present invention is based on an end-to-end communication method of area terminals, establishes communication channels in different areas, and realizes decentralized point-to-point interactive localized communication deployment between areas through the software and hardware decoupling mode of the area terminals.

[0058] With the rapid development of the Internet of Things and blockchain technology, the number of terminals connected to the power Internet of Things system has increased dramatically, and the existing centralized network structure faces challenges in scalability and data security. Decentralized network architecture can significantly reduce the risk of single point failures, while ensuring data security and privacy protection through blockchain technology, becoming an ideal solution.

[0059] The multi-station multi-fusion terminal point-to-point decentralized communication networking method proposed in the present invention can effectively solve the scalability and security problems of the traditional centralized architecture, and can support different types of terminal devices to access the network in a plug-and-play manner. It provides reliable technical support for the development of the future power Internet of Things and provides a large amount of intelligent support for the low-carbon, economical and safe operation of the new distribution system.

[0060] The present invention provides a multi-station multi-fusion terminal point-to-point decentralized communication networking method. On the basis of constructing a multi-station multi-fusion terminal decentralized interaction architecture, a multi-station multi-fusion terminal point-to-point decentralized communication networking method that supports plug-and-play and flexible expansion is studied, which is matched with the centralized interaction architecture to achieve the complementary mechanism of "end-to-end" collaboration and "edge-to-cloud" collaboration and "edge-to-end" intercommunication, and support the distributed collaborative optimization scheduling of flexible resources in multiple stations for distribution network voltage reactive power control and optimal decomposition of demand response instructions;

[0061] The present invention proposes a multi-station multi-fusion terminal point-to-point decentralized communication networking method, which can effectively solve the scalability and security problems of the traditional centralized architecture. By introducing blockchain technology, the system has a high degree of flexibility, security and scalability, and can support different types of terminal devices to access the network in a plug-and-play manner, providing reliable technical support for the development of the future power Internet of Things.

Therefore, the present invention includes but is not limited to the embodiments described in the specific implementation modes. Any other implementation modes derived by those skilled in the art based on the technical solutions of the present invention also fall within the scope of protection of the present invention.
