[0001] The present invention belongs to the technical field of heterogeneous network emergency communication and fuzzy machine learning, and relates to an electric power heterogeneous network fusion emergency communication device, in particular to an electric power heterogeneous network fusion emergency communication device based on space Internet. Background Art

[0002] The power system is an important foundation of modern society. However, due to the wide coverage, long routes and open deployment of transmission lines, equipment is prone to failure and is easily affected by natural disasters, man-made damage and other factors. Therefore, the construction of emergency communications is of great significance. The establishment of an emergency communication system can help relevant personnel in the power system to build channels for emergency contact and information transmission, so as to take emergency measures in time and ensure the safe and reliable operation of the power system.

[0003] Under the current technical background, although the power heterogeneous network integrated emergency communication device has improved the efficiency and reliability of power emergency communication to a certain extent, it still has some key defects and shortcomings, which limit its application capabilities and response speed in complex environments.

[0004] The main problems include: 1. Limited communication coverage: The existing power heterogeneous network convergence emergency communication devices have limitations in coverage, especially in special environments such as remote areas or underground facilities, and it is difficult to achieve comprehensive and stable signal coverage. 2. Low communication efficiency: In an emergency, the existing power heterogeneous network convergence emergency communication devices cannot provide sufficiently high communication bandwidth and data transmission rate, which limits the ability of the emergency response team to collect and transmit key information. 3. Insufficient real-time performance: In a rapidly changing emergency environment, the existing power heterogeneous network convergence emergency communication devices cannot provide a fast enough information exchange speed, which leads to delays in decision-making and response. 4. Weak information security: The existing power heterogeneous network convergence emergency communication devices lack sufficient information encryption and security authentication mechanisms, which makes the transmitted sensitive data (such as power grid operation status, fault information, etc.) face the risk of leakage and malicious use. 5. Poor equipment compatibility and interoperability: The existing power heterogeneous network convergence emergency communication devices have compatibility issues between different types of power heterogeneous networks, resulting in low efficiency of cross-network communication. 6. Complex deployment and maintenance: The existing power heterogeneous network convergence emergency communication devices require complex technical support and maintenance, which increases the difficulty of deployment and operation in emergency situations. 7. High cost and resource consumption: Building and maintaining an extensive emergency communication network involves high costs and resource consumption. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and propose a power heterogeneous network fusion emergency communication device based on spatial Internet, which can improve the performance and reliability of the power emergency communication system.

[0006] The present invention solves the practical problem by adopting the following technical solutions:

[0008] Moreover, the power heterogeneous network fusion module includes: a terminal interface module, a data processing module, a data encryption module, an output interface module and a security log supervision module; the terminal interface integrates multiple terminal interfaces including wired network, Bluetooth, Lora narrowband signal, etc., and transmits terminal data to the data processing module, obtains key and valid data through the data processing module, and outputs the data through the output interface module after data encryption; the security log module is responsible for supervising and counting the working status and alarm information of all interfaces and sub-modules in the power heterogeneous network fusion module.

[0009] Moreover, the emergency communication embedded device is used to provide physical support for the power heterogeneous network fusion module, the space Internet communication module and the power supply module, which is convenient for deployment on various carrier platforms and data access.

[0010] Moreover, the space Internet communication module includes: a network communication module, a business control, a fuzzy logic vector machine module, a network virtualization module and a relay networking module; the network communication module will integrate the networks and data of the broadband satellite, narrowband satellite, long-distance relay networking and power heterogeneous network integration modules; the network virtualization module virtualizes and maps the various types of heterogeneous networks connected to realize cross-domain integrated networking; the fuzzy logic vector machine module provides algorithms and analysis processing based on fuzzy logic vector machines, and provides network communication decisions and optimization solutions; the relay networking module can realize self-organizing network access of long-distance relay networks, and realize the construction of emergency networks in power rescue environments by accessing the network; the business control module uses fuzzy logic vector machine technology to control the data and communication solutions of the corresponding business, and expands the network coverage through the network communication module.

[0011] Moreover, the data encryption module uses a lightweight symmetric encryption algorithm to encrypt the communication data, and the specific encryption steps include:

[0012] (1) A random factor is introduced into the encryption method to generate the key K;

[0013] (2) The data sender obtains unencrypted plaintext data P from multiple terminals and uses the AES encryption function. Let the AES encryption function be E, then the ciphertext C = E(K, P). The plaintext data P is encrypted by the AES encryption function E. After multiple rounds of the process, the ciphertext C is obtained. The encrypted data is sent to the data receiver through the network.

[0014] (3) After the data receiver receives the ciphertext C, the encryption function E uses the ciphertext C to infer the data plaintext P, thereby completing the data encryption process.

[0015] Moreover, the fuzzy logic vector machine module applies fuzzy logic and support vector machine to manage heterogeneous network deployment.

[0025]

[0026] According to any data point (x i ,y i ) to the required hyperplane, the distance is minimized, and the optimization problem is transformed into:

[0027]

Its mathematical form is expressed as follows:

[0071] T={(x1,y1),(x2,y2),…,(x N ,g N ))}

[0072] Among them, each x and y represents the fuzzification result of a communication parameter, forming a data set.

[0107] Multi-dimensional network support: Integrate multiple communication methods and flexibly adjust network architecture and functions according to the specific needs of different application scenarios.

[0108] The working process of the present invention is:

[0109] 1. When the system starts, each module performs initialization, loads the necessary configuration and dependencies, and ensures that all interfaces and communication protocols operate normally.

[0110] 2. The power heterogeneous network fusion module receives data through multi-terminal interfaces, and after processing and specific encryption, transmits it to the space Internet communication module. The space Internet communication module integrates on-site broadband self-organizing network communication with narrow broadband satellite communication, integrates multi-terminal data, solves the problem of poor compatibility and interoperability in existing technologies, and provides diverse and reliable remote data transmission services.

[0112] 4. The power heterogeneous network fusion module monitors and manages the data flow of each module in real time to ensure the effective integration of the source data of each terminal. At the same time, the space Internet communication module separates the network function from the dedicated hardware by implementing the virtualization of the network function, thereby improving the flexibility and programming capabilities of the system.

[0113] 5.

[0115] 7. The device is not limited to fixed installation in a specific emergency scenario, but can be reused in any emergency scenario, achieving quick and convenient deployment and network construction, reducing costs and resource consumption.

[0116] The design process of the present invention is:

[0117] Step 1. Design a power heterogeneous network fusion module by implementing a highly integrated device on the power transmission carrier, including components such as data input, data processing, signal encryption, data output, and security log supervision, and communicate the data information processed inside the module with the space Internet communication module in step 2 to achieve autonomous and controllable flexible emergency power grid data communication guarantee.

[0118] The data encryption module uses a lightweight symmetric encryption algorithm to encrypt communication data by considering security and efficiency, ensuring confidentiality during data transmission. The AES encryption function is used for the unencrypted plaintext data accessed by multiple terminals. The AES encryption function is E, then C = E (K, P), and the plaintext data P is encrypted by the AES encryption function E to obtain the ciphertext C. In order to enhance security, a randomization factor is introduced to generate the key K and the initial vector, avoiding the use of a fixed lookup table (S box), thereby reducing security risks.

[0119] Step 2. Design a space Internet communication module to meet the needs of long-distance data transmission integrated with narrow-bandwidth satellite communications. It can be integrated with on-site broadband communication support equipment and relay terminals to provide technical support for ultra-long-distance data transmission relays.

[0120] The Space Internet Communication Module automatically selects narrowband or broadband satellite communication to transmit data through business analysis. For example, narrowband communication is suitable for voice calls and control instructions, while broadband communication is suitable for high-definition video and file transmission. By combining the two, transmission efficiency and quality can be flexibly balanced.

[0121] The space Internet communication module adopts network function virtualization to abstract satellite communication hardware equipment into structural objects in the software, which is convenient for flexible deployment and management. Such a design can integrate the firewall, intrusion detection system and load balancer of the power emergency network to ensure the security of the communication control module.

[0122] In view of the complex power emergency communication scenarios, the fuzzy logic vector machine module applies fuzzy logic and support vector machines to manage heterogeneous network deployment, solve the uncertainty and ambiguity problems in signal transmission, and improve the performance of the communication system. Based on fuzzy set theory, the module uses fuzzy logic to process uncertain and fuzzy information in the power emergency communication system. By monitoring system parameters such as node location, communication load and equipment status, this information is converted into fuzzy sets, and then converted into specific outputs through mapping relationships, thereby improving the adaptability and reliability of the system. The mapping relationship is as follows:

[0123]

[0124] in Represents the fuzzy sets generated by various fuzzy factors in the power emergency environment. The expression needs to map out a clear set, that is, the required weight value.

[0125] By extracting and selecting the characteristic vector matrix of the data of the power emergency communication system, fuzzy logic is applied to establish the mapping relationship between the system status and the communication guarantee service in order to adapt to the diversity of the transmission environment. Its mathematical form is expressed as follows:

[0126] T={(x1,y1),(x2,y2),…,(x N ,y N ))}
