Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0044] As Figure 1 shown, an intelligent flexible regulation terminal collaborative communication method based on 5G LAN provided by an embodiment of the first aspect of the present application includes:

[0045] Step 100: Configure a PDN session of Ethernet type using AT commands, and set the access point name to connect the intelligent flexible regulation terminal to the 5G LAN network.

[0046] Step 200: Enable the 5G LAN dialing function to enable the intelligent flexible regulation terminal to perform a 5G LAN dialing connection.

[0047] Step 300: In a 5G LAN network environment, use ping packets to test the interoperability between the intelligent flexible regulation terminal and each power device.

[0048] Step 400: Select at least one intelligent flexible regulation terminal as the management terminal, and establish a network connection between the management terminal and the metering master station, where the management terminal is used for routing and forwarding operation data of the power system.

[0049] In step 100, first, confirm that all intelligent flexible regulation terminals and their environments (including modules and networks) support 5G LAN technology. Use a professional tool (such as the logel tool) to capture network-related logs (Log) to check whether the current network environment supports 5G LAN. If the logel tool shows is_enable: 1, it means that the current network environment supports 5G LAN; otherwise, it is necessary to switch to a network environment that supports 5G LAN.

[0050] Next, use the AT command to configure an Ethernet-type PDN (Packet Data Network) session. Specifically, use the command AT+CGDCONT= <cid>,"Ethernet"," <apn>"Configure a PDN session of Ethernet type and set the correct Access Point Name (APN) to access the 5G LAN network.

[0051] Finally, use the AT+QNETDEVCTL command to perform the dialing operation so that the intelligent flexible control terminal can access the 5G LAN network.

[0052] This process not only ensures that the intelligent flexible control terminal can correctly access the 5G LAN network, but also provides the necessary network configuration and support for subsequent data transmission and services. In this way, the intelligent flexible control terminal can work efficiently with other devices in the 5G LAN network, improving the efficiency and reliability of data transmission and providing technical support for the stable operation of the power system.

[0053] In step 200, use the dedicated AT command AT+QCFG="5glan", <cid> , <enable>To enable the 5G LAN dialing function, the purpose is to enable the intelligent flexible control terminal to have the ability to make 5G LAN dialing connections. Among them, <cid>Represents a connection identifier, <enable>It is a boolean value used to enable or disable the 5G LAN dialing function.

[0054] This operation enables the intelligent flexible control terminal to perform a dial-up connection in a 5G LAN network environment, thereby achieving efficient data exchange with power equipment. By enabling the 5G LAN dialing function, the intelligent flexible control terminal can better meet the requirements of modern power systems for data transmission rate and reliability, ensuring the timely transmission and processing of power system operation data.

[0055] In step 300, after completing the network configuration of the intelligent flexible control terminal and successfully establishing a 5G LAN connection, it is first necessary to confirm whether the network connection is normal. This can be done by checking the network status indicator on the terminal device or using AT commands to query the network connection status.

[0056] Once it is confirmed that the intelligent flexible control terminal has successfully accessed the 5G LAN network, the ping test can then be started. The ping test is usually achieved by sending ICMP (Internet Control Message Protocol) echo request packets to the target device and receiving the response packets. This test can be used to verify the connectivity between the intelligent flexible control terminal and the power equipment and to evaluate the network latency.

[0057] Observe the results returned by the ping command, record the round-trip time (RTT) for each request, and whether there is any packet loss. If most of the ping requests can get a response and the average RTT is within an acceptable range (depending on the requirements of the specific application), it indicates that the network interoperability between the intelligent flexible control terminal and the power equipment is good; if there is a high packet loss rate or large RTT fluctuations, it may mean that there are some problems with the network and further troubleshooting is required.

[0058] By performing the above steps, the interoperability between the intelligent flexible control terminal and the power equipment at the network level can be effectively detected, ensuring unobstructed data transmission and providing network-level support for the stable operation of the power system. In addition, the ping test can also help maintenance personnel discover and solve network faults in a timely manner, ensuring the normal operation of the power system.

[0059] In step 400, the criteria for selecting the management terminal can include the following points:

[0060] Computing power: Select an intelligent flexible control terminal with sufficient computing resources as the management terminal to ensure that it can handle complex routing algorithms and a large amount of data traffic.

[0061] Communication capabilities: Priority is given to terminals with stronger communication capabilities and more stable network connections because they can communicate with other devices more effectively.

[0062] Security: Considering the importance of management terminals, devices with a high level of security protection should be selected to prevent unauthorized access and data leakage.

[0063] Reliability: Select terminals with stable historical performance and low failure rate as management terminals to ensure the continuity and reliability of power system operation data.

[0064] Establishing a network connection with the metering master station can include the following points:

[0065] Network configuration: Ensure that the management terminal has correctly configured its network parameters, such as IP address, subnet mask, default gateway and other information, so as to establish a connection with the metering master station.

[0066] Security protocol: Use security protocols (such as TLS / SSL) to encrypt the communication between the management terminal and the metering master station to protect the security of data during transmission.

[0067] Authentication mechanism: Implement a two-way authentication mechanism to ensure the identities of both parties are credible and prevent man-in-the-middle attacks or other forms of security threats.

[0068] Connection test: Before the service is officially put into use, a comprehensive connection test is conducted, including but not limited to network connectivity test, data transmission test, etc., to ensure that the connection is stable and reliable.

[0069] The functions of the management terminal are as follows:

[0070] Data routing: As an important node in the network, the management terminal is responsible for accurately sending data packets from different sources to the destination according to predetermined routing rules.

[0071] Data forwarding: In addition to simple routing functions, the management terminal is also responsible for processing and forwarding power system operation data to ensure that the data can reach the correct recipient in a timely manner.

[0072] Load balancing: In a multi-terminal collaboration scenario, the management terminal also needs to assume certain load balancing functions to reasonably allocate data processing tasks and avoid single-point overload.

[0073] By implementing the above measures, we can not only ensure the effective management and efficient transmission of power system operation data, but also greatly improve the reliability and safety of the entire power system. In addition, through refined management and scheduling, it will also help optimize resource allocation, reduce operating costs and improve service quality.

[0074] According to the intelligent flexible regulation terminal collaborative communication method based on 5G LAN provided by the first aspect embodiment of the present application, first, use AT commands to configure a PDN session of Ethernet type, and set the access point name to connect the intelligent flexible regulation terminal to the 5G LAN network. In this step, first use the logel tool to check whether the current network environment supports 5G LAN technology. If it supports, configure a packet data network (PDN) session of Ethernet type through AT commands, and set the correct access point name (APN) to connect the intelligent flexible regulation terminal to the 5G LAN network. In this way, it is ensured that the intelligent flexible regulation terminal can access the 5G LAN network environment efficiently and securely, laying a good network foundation for subsequent data transmission; then, enable the 5G LAN dialing function to enable the intelligent flexible regulation terminal to make a 5G LAN dialing connection. Specific AT commands can be used (such as AT+QCFG="5glan", <cid> , <enable>)Enable the 5G LAN dialing function to allow the intelligent flexible control terminal to make a dial-up connection through the 5G LAN network. After enabling the dialing function, the intelligent flexible control terminal can initiate a 5G LAN connection actively, achieving seamless docking with the network and enhancing the flexibility and availability of the device in the network. The third step is to test the interoperability between the intelligent flexible control terminal and each power device in the 5G LAN network environment. After successfully establishing a 5G LAN connection, test the interoperability between the intelligent flexible control terminal and other power devices by sending an ICMP echo request message (i.e., ping packet) to the target device and waiting for a response. Statistically analyze the round-trip time of the ping packet to determine the network delay parameter. Through the ping test, the quality of the network connection can be effectively verified, ensuring smooth data transmission. At the same time, potential network problems can be quickly identified, improving the robustness of the overall network. Finally, select at least one intelligent flexible control terminal as the management terminal and establish a network connection between the management terminal and the metering master station. Among them, the management terminal is used for routing and forwarding the operation data of the power system. Select a qualified intelligent flexible control terminal as the management terminal according to standards such as 5G communication channel parameters, data processing capacity parameters, and terminal authentication mechanism parameters, and establish an encrypted channel with the metering master station to ensure the security of data transmission. Such a mechanism not only optimizes the processing process of the operation data of the power system but also realizes the efficient routing and forwarding of data through the selected management terminal, further improving the overall performance and reliability of the system. In summary, the intelligent flexible control terminal collaborative communication method based on 5G LAN provided by this application realizes the efficient collaborative communication of the intelligent flexible control terminal under the 5G LAN network, significantly improving the transmission efficiency and reliability of the operation data of the power system.

[0075] In some embodiments of this application, use AT commands to configure a PDN session of Ethernet type and set the access point name to connect the intelligent flexible control terminal to the 5G LAN network. Specifically:

[0076] Use the logel tool to capture network-related logs to check whether the current network environment supports 5G LAN technology. If the logel tool shows is_enable:1, it means that the current network environment supports 5G LAN;

[0077] Use AT commands to configure a PDN session of Ethernet type. The specific command is: AT+CGDCONT= <cid>,"Ethernet"," <apn>";

[0078] Execute the dialing operation using the AT+QNETDEVCTL command to enable the intelligent flexible control terminal to access the 5G LAN network.

[0079] Specifically, the logel tool is a professional tool for capturing network-related logs. Through it, we can obtain information about the current network environment. Run the logel tool and view the output log information, paying special attention to the part related to 5G LAN. If the log shows is_enable:1, it indicates that the current network environment supports 5G LAN technology, which means we can continue with the subsequent configuration steps. After confirming the support, we can prepare for the network access configuration of the intelligent flexible control terminal.

[0080] Through the AT command AT+CGDCONT= <cid>,"Ethernet"," <apn>"to configure a PDN session of the Ethernet type. Here, <cid>is a connection identifier that identifies a specific PDN connection configuration, " <apn>"The APN (Access Point Name) is specified and used to connect to a specific service provider network. Ensure that the APN used is the correct one for accessing the 5G LAN network, which is usually provided by the service provider.

[0081] Execute the dialing operation using the AT+QNETDEVCTL command. This command is used to activate the previously configured PDN session, enabling the intelligent flexible control terminal to communicate via the 5G LAN network. After executing the dialing command, it should be confirmed that the intelligent flexible control terminal has successfully accessed the 5G LAN network. The connection status can be verified by checking the status of the terminal or using other AT commands.

[0082] Through the above steps, we not only ensure that the intelligent flexible control terminal can smoothly access the 5G LAN network, but also provide a stable and reliable network connection environment for the terminal device. This step is the basis for achieving subsequent efficient data transmission and collaborative work between terminals. Through the application of 5G LAN technology, the operation efficiency of the power system can be greatly improved, the real-time performance and security of data transmission can be enhanced, and ultimately the intelligent management level of the power system can be promoted.

[0083] In some embodiments of the present application, the 5G LAN dialing function is enabled to allow the intelligent flexible control terminal to perform 5G LAN dialing connection, specifically:

[0084] Use the AT command AT+QCFG="5glan", <cid> , <enable>To enable the 5G LAN dialing function.

[0085] Specifically, using AT commands to enable the 5G LAN dialing function includes the following steps:

[0086] Determine the configuration parameters:

[0087] <cid>: Connection identifier, used to identify a specific PDN connection configuration.

[0088] <enable>: A boolean value used to control whether the 5G LAN function is enabled. If set to 1, it is enabled; if set to 0, it is disabled.

[0089] Execute the AT command:

[0090] Use the AT command AT+QCFG="5glan", <cid> , <enable>To enable the 5G LAN dialing function. For example, if you want to enable the 5G LAN function for the PDN session with connection identifier 1, you can enter AT+QCFG="5glan",1,1.

[0091] Before configuration, ensure that the intelligent flexible control terminal has been successfully configured with an Ethernet-type PDN session through the previous steps, and it has been confirmed that the current network environment supports 5G LAN technology.

[0092] When executing the instruction, send the above AT instruction to the intelligent flexible control terminal through the serial port or other appropriate interfaces to enable the 5G LAN function. This step ensures that the terminal can utilize the 5G LAN characteristics for subsequent dial-up connections.

[0093] Finally, confirm the enabled status, that is, after sending the instruction, the terminal should return a confirmation message indicating that the 5G LAN function has been successfully enabled. You can confirm whether the function is correctly enabled by checking the returned status code.

[0094] Through the above steps, the intelligent flexible control terminal can successfully enable the 5G LAN dialing function, thus allowing it to connect through the 5G LAN network. This not only improves the communication efficiency between terminal devices but also provides a solid technical support for the efficient operation of the power system.

[0095] In some embodiments of the present application, in a 5G LAN network environment, use ping packets to test the interoperability between the intelligent flexible control terminal and each power device. Specifically:

[0096] In a 5G LAN network environment, send an ICMP echo request packet to the target device and wait for a response;

[0097] Statistical ping packet round-trip time to determine the network delay parameter.

[0098] Prepare before testing, specifically including:

[0099] Confirm the connection status: Ensure that the intelligent flexible control terminal has been successfully connected to the 5G LAN network and the network connection status is stable.

[0100] Target device selection: Determine the target power device for which interoperability needs to be tested and record its IP address or other network identifiers.

[0101] Test environment setup: Prepare a command-line interface or other tools capable of executing the ping command.

[0102] Execute the ping command: Execute the ping command on the command-line interface of the intelligent flexible control terminal. The basic format of the command is usually ping [IP address] [-c number of echo requests], where [IP address] is the IP address of the target power device, and the -c option is used to specify the number of echo requests to send.

[0103] For example, if the IP address of the target device is 192.168.1.100 and you want to send 5 echo requests, you can execute ping 192.168.1.100 -c 5.

[0104] After executing the ping command, the terminal will send an ICMP echo request packet to the target device and wait for a response. The response packet will contain information about the round-trip time of the data packet.

[0105] The ping command will report the round-trip time of each echo request, which is the time it takes for the data packet to travel from the intelligent flexible control terminal to the target device and back. By statistically calculating the average round-trip time of multiple ping operations, the network delay parameter can be evaluated. A lower average RTT means better network performance. The ping command will also report whether there is any packet loss. If the packet loss rate is high, it may indicate a problem with the network connection and further troubleshooting is required.

[0106] Through the above steps, the interoperability between the intelligent flexible control terminal and each power device can be effectively tested, and the timeliness and reliability of data transmission can be ensured. This helps to maintain the normal operation of the power system and provides a basis for subsequent data communication optimization.

[0107] In some embodiments of the present application, at least one intelligent flexible control terminal is selected as the management terminal, and a network connection is established between the management terminal and the metering master station. Specifically:

[0108] Set the 5G communication channel parameters, data processing capacity parameters, and terminal authentication mechanism parameters of the management terminal, and select a compliant intelligent flexible control terminal as the management terminal based on the 5G communication channel parameters, data processing capacity parameters, and terminal authentication mechanism parameters;

[0109] Establish an encrypted channel between the management terminal and the metering master station to enable data transmission between the management terminal and the metering master station;

[0110] During data transmission, the management terminal processes the power system operation data based on the data processing capacity parameters.

[0111] The 5G communication channel parameters include indicators such as signal strength, signal-to-noise ratio, and frequency band, which reflect the communication capabilities of the terminal in the network.

[0112] The data processing capacity parameters cover hardware performance indicators such as CPU processing speed, memory size, storage capacity, as well as software processing capabilities such as concurrent processing ability, data compression and decompression speed, etc.

[0113] The terminal authentication mechanism parameters involve security measures such as authentication, encryption method, access control list (ACL), etc., to ensure that only authenticated terminals can become management terminals.

[0114] Based on the above parameters, comprehensive evaluation is carried out on each intelligent flexible regulation terminal, and the device with the best performance and stability is selected as the management terminal. In addition, factors to be considered can also include the historical performance of the terminal, failure rate, energy consumption, etc.

[0115] Configure an encryption mechanism between the selected management terminal and the metering master station, such as using the TLS / SSL protocol or other appropriate encryption technologies, to ensure the security of data transmission. Use the corresponding network configuration tools to establish an encrypted channel between the management terminal and the metering master station. This involves steps such as configuring firewall rules and setting security certificates. After the encrypted channel is established, verify the reliability and security of the connection by sending test data packets, etc., to ensure that data can be securely transmitted between the two ends.

[0116] During the data transmission process, the management terminal processes the power system operation data according to its data processing capacity parameters. This includes but is not limited to preprocessing steps such as data screening, sorting, compression, and encryption. The processed data will be transmitted to the metering master station through the established encrypted channel to ensure the integrity and security of data transmission.

[0117] Through the above steps, the management terminal can be effectively selected and configured to ensure that the data transmission between it and the metering master station is both efficient and secure. The selection of the management terminal is based on strict performance and security standards, and the establishment of the encrypted channel further strengthens the security of data transmission. This process not only improves the management efficiency of power system operation data but also provides a solid guarantee for the stable operation of the system.

[0118] In some embodiments of the present application, the power system operation data includes power quality data, equipment status data, power grid operation data, fault record data, and power load data.

[0119] The power quality data mainly reflects the power quality situation in the power grid, including but not limited to data in aspects such as voltage, current, and frequency. Specifically, it can include the following content:

[0120] Voltage level: Record the voltage values of each node in the power grid to ensure that the voltage remains within a safe range.

[0121] Current situation: Monitor the current intensity in the line to prevent overload.

[0155] In some embodiments of the present application, the network delay parameter range is from 1 millisecond to 10 milliseconds. The network delay parameter refers to the time required for a data packet to be transmitted from the sender to the receiver in network communication, also known as the Round-Trip Time (RTT). In this scenario, the range of the network delay parameter is defined as from 1 millisecond to 10 milliseconds, meaning that in the communication between the intelligent flexible control terminal and the power equipment, the round-trip time for the data packet from being sent to being received should be within this interval.

[0156] This low-latency parameter is very important for real-time communication in power systems because it directly affects the immediacy and reliability of data transmission. For example, in the monitoring and control system of the power grid, if the transmission latency of data is too high, it may lead to the delayed execution of control instructions, thereby affecting the stability and security of the power grid. Therefore, ensuring that the network latency parameter is within a lower range can improve the efficiency and reliability of power system operation.

[0157] In a 5G LAN network environment, achieving network latency parameters of 1 millisecond to 10 milliseconds indicates that the network has very high real-time and low-latency characteristics. This is very beneficial for application scenarios that require instant response, such as remote control and automated operations. By keeping the network latency at a lower level, it can ensure that the real-time data of the power system can be transmitted quickly and accurately, thus supporting more efficient operation and management of the power system.
