[0031] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0032] Example 1, reference Figure 1 , is an embodiment of the present invention, and provides a method for configuring an intelligent communication fault diagnosis device for power distribution operation and maintenance, comprising:

[0033] S1: Setting an interface for connecting to a first terminal.

[0034] In an embodiment of the present application, setting an interface for connecting to the first terminal includes setting an Ethernet interface and a configurable communication interface for connecting to the first terminal.

[0035] The first terminal may be a distribution automation terminal, which is a device used for automatic control, monitoring and protection in a distribution system. The terminal includes a protection relay, an intelligent switch controller, a distributed energy resource interface, etc.

[0036] The Ethernet interface provides standard network connection and supports fast data transmission. It is suitable for distribution automation terminals that support TCP / IP network communication and can realize remote control and monitoring.

[0037] Configurable communication interfaces support multiple communication standards, such as RS-232, RS-485, etc. These interfaces can be configured through software to match specific communication protocols and physical connection requirements. Used for distribution automation terminals of different models or manufacturers, especially those old equipment that may not support standard Ethernet connections.

[0038] It should be noted that the communication requirements must support industry standard communication protocols such as IEC 60870-5-101 or 104, DNP3, etc., which are commonly used for communication in power systems. It is necessary to be able to process commands from the central control room or field operations, report data and receive control commands.

[0039] S2: Analyze the communication protocol standard supported by the first terminal and determine the message sending order.

[0040] The communication protocol standards supporting the first terminal are analyzed, including information body address length, general call telesignaling type, general call telemetry type, remote control type, and SOE upload type.

[0041] In the embodiment of the present application, the communication protocol standard may be IEC 60870-5-101 / 104: 101 is a serial communication protocol suitable for slower data links. 104 is a network version of 101, based on TCP / IP, suitable for faster Ethernet communication. The main functions include telemetry (real-time data measurement), telesignaling (state change), remote control (remote control of equipment), and remote adjustment (adjustment of equipment settings).

[0042] In an optional embodiment, the communication protocol standard may also be, DNP3 (Distributed Network Protocol version 3): widely used in the power industry, supporting a wide range of control and monitoring functions. Powerful time synchronization and data object confirmation mechanism to improve data integrity and communication reliability. Modbus is a simple communication protocol widely used in industrial environments, including serial (Modbus RTU) and TCP / IP (Modbus TCP) versions, usually used for sending simple instructions and reading and writing data between devices.

[0043] In the embodiment of the present application, the message sending sequence may be determined by considering the characteristics of the communication protocol and the network environment when determining the message sending sequence. Specifically, it includes: an example message sending sequence A1 to A7 based on the IEC 60870-5-104 protocol.

[0044] A1, establish a connection, send a start frame, and establish a connection between the client and the server.

[0045] A2, time synchronization, sends a time synchronization command to synchronize the system time of the first terminal and the control center.

[0046] A3, general call, sends a general call command to request the distribution automation terminal to send the current values ​​of all data points it monitors.

[0047] A4, cyclic task, telemetry data, periodically requests or automatically receives measurement data such as voltage and current.

[0048] A5, remote signaling data, monitors important events and status changes, such as circuit breaker switch status. Performs switch operations or setting adjustments as needed and sends control commands.

[0049] A6, heartbeat detection, regularly sends heartbeat signals to maintain the active state of the connection and detect the health of the link.

[0050] A7, end communication: send a stop frame and close the connection normally.

[0051] In an optional embodiment, the message sending method may also be a priority-based message sending method, specifically including B1 to B4.

[0052] B1, Define message priorities. Determine the priorities of different types of messages. Remote control commands (such as switching circuit breakers) may be given the highest priority, while routine data collection (such as telemetry data) may have a lower priority. Develop priority rules based on urgency, frequency of occurrence, and data size.

[0053] B2, Implement a priority queue Select or develop priority queue management software for your system. This may involve programming to create a data structure, such as a heap or multi-level queue, to store messages to be sent. Integrate the priority queue into an existing data processing system to ensure that it can receive and classify messages to be sent.

[0054] B3, message classification and queuing, when the system generates or receives a message, it automatically classifies the message and puts it into the corresponding priority queue according to the defined priority rules. When the message arrives at the queue system, an automatic trigger mechanism is implemented to process and sort the message according to its priority.

[0055] B4, Sending Mechanism Implementation, Develop or configure a message sending scheduler that periodically checks the messages in the priority queue and sends the messages in order from high to low priority. Ensure that the scheduler can handle high-priority messages that arrive at the same time, and prioritize these messages when the system load is high.

[0056] It should be noted that when designing the system, the priority of the messages needs to be considered, for example, remote control commands usually have a higher priority than telemetry data. Appropriate error handling mechanisms need to be implemented to deal with communication interruptions or data errors. Security measures, encryption and authentication, should also be taken into account to protect the communication data from attacks.

[0057] Example 2, reference Figure 2 , is an embodiment of the present invention, and provides a method for configuring an intelligent communication fault diagnosis device for power distribution operation and maintenance, comprising:

[0058] S3: Configure the first simulation station according to the information obtained from the main station.

[0059] Configuring the first simulation station includes simulating the functions of the master station and building an intelligent communication fault diagnosis master station suitable for power distribution operation and maintenance.

[0060] The first simulation station can be a portable simulation master station, a power system simulation master station, an industrial automation simulation master station, a network simulation master station, a field bus simulation master station, etc.

[0061] In an embodiment of the present application, configuring the first simulation station includes:

[0062] Step 1, Data Interface Definition Establish the communication interface between the portable simulation master station and the main station. You can choose to use TCP / IP, RS-485 or other communication interfaces, depending on the interface type of the main station. Use standard transmission protocols (such as IEC60870-5-104, DNP3 or Modbus) to ensure correct data transmission.

[0063] Step 2, parameter acquisition and data analysis: After receiving the data packet from the master station, parse the data. Use the analysis function P(x) to convert the raw data into a parameter format readable by the portable analog master station. Check each parameter item to ensure data accuracy. The formula is expressed as:

[0064] Parameter = P(x)

[0065] Among them, x is the original data received from the master station, and P(x) is the parsing function that converts the data into a standard parameter format.

[0066] Step 3, store the parsed parameters in the memory of the portable analog master station for subsequent configuration. If the parameters need to be stored for a long time, they can be written to the storage medium of the master station (such as EEPROM or SD card). Synchronization cycle, the synchronization cycle T provided by the master station is expressed as:

[0067] T=T master +ΔT

[0068] Among them, T master is the time of the master station, and ΔT is the synchronization offset.

[0069] Step 4, configure the portable simulation master station, read the configuration data from the parameters stored in step 3, and load it into the system configuration module of the portable simulation master station. Use the read function L(y) to access the parameter y in the memory and set it to each module of the portable simulation master station. The formula is expressed as:

[0070] Config_value=L(y)

[0071] Where y represents the stored parameters, and L(y) is used to read the parameters from the storage.

[0072] Step 5, set the communication protocol stack according to the protocol type obtained from the master station. Configure the protocol stack such as IEC 60870-5-101 / 104 or DNP3, and set parameters such as the message body address length, general call telesignal type, etc. If the time information is obtained from the master station, the portable analog master station needs to synchronize its own clock. The time synchronization formula is expressed as:

[0073] T local =T master +ΔT

[0074] Among them, T local is the local time of the portable analog master station, T master is the master station time, and ΔT is the synchronization adjustment value.

[0075] In an optional embodiment, the first simulation station may also be configured using a preset script configuration, specifically including C1-C4.

[0076] C1, develop a set of APIs for script calls, which can control various functions of the simulated master station, such as parameter setting, protocol selection, data sending, etc.

[0077] C2, API should provide adequate error handling and status feedback so that scripts can adapt to different operating conditions. Integrate a script interpreter, such as Python interpreter, into the simulation master software. Ensure that the interpreter can run stably on the master operating system, including script loading, execution, and exception handling.

[0078] C3, Scripting: Provides sample scripts and documentation to help users quickly learn how to write scripts to control the analog master station. Demonstrates how to read configuration files, set parameters, execute commands, and process responses through scripts.

[0079] C4, user script management, allows users to upload scripts over the network or directly on the device. Provides script management functions, including version control, execution permission settings, and script logging.

[0080] It should be noted that the heartbeat interval configuration sets the heartbeat parameters of the portable simulation master station according to the heartbeat interval provided by the master station to maintain the active state of the connection.

[0081] S4: Connect the first simulation station and conduct a test after confirming the wiring.

[0082] Further, such as Figure 2 As shown in the figure, after the settings are completed, export the configuration file from the portable analog master station, synchronize it with the distribution network automation terminal, and complete the configuration of both the master and slave ends. Then connect the portable analog master station with a shielded twisted pair cable. After confirming the wiring, test it. If you encounter any problems, adjust the secondary side wiring of the complete set factory. Finally, complete the on-site test of the communication protocol.

[0083] Furthermore, export the configuration file and use the configuration management software to export the setting parameters into a standard format file (such as XML, JSON). Implement an automated script or program to verify the integrity and correctness of the configuration.

[0084] Synchronize configuration to the distribution network automation terminal and push the configuration file to the terminal through the network using FTP, HTTP or dedicated tools. Manually update the configuration using physical media such as USB. Use batch scripts or automation tools to perform the configuration loading and application process.

[0085] Calculate signal attenuation, especially over long distances:

[0086]

[0087] Among them, P in is the input power, P out is the output power.

[0088] Connect the portable analog master station, ensuring that industry-standard shielded twisted pair cables are used to reduce electromagnetic interference. Check the physical connections for contact quality and continuity.

[0089] Perform system testing to monitor communication quality and data integrity using network analysis tools and protocol analyzers. Perform functional testing such as sending control commands and verifying responses.

[0090] Perform network delay calculations, problem adjustments and secondary wiring, use electrical test instruments to detect connection point voltage and current, and identify wiring problems. Adjust wiring configuration or replace damaged components to improve system stability and performance. Calculate wiring resistance to ensure compliance with safety standard procedures.

[0091] Complete on-site testing, conduct continuous operation testing and long-term stability testing, record and analyze test data, and evaluate system performance.

[0092] Example 3: The following is an embodiment of the present invention, which provides an intelligent communication fault diagnosis device configuration system for distribution operation and maintenance, including a communication intelligent diagnosis module, a human-computer interaction module, a communication interface module, a built-in battery module, an intelligent analysis module, and a parameter configuration module.

[0093] Among them, the communication intelligent diagnosis module is responsible for detecting and diagnosing the status and errors of the communication interface, and automatically identifying and prompting communication problems.

[0094] The human-computer interaction module provides an interface for operators to perform equipment settings, configuration export, and message viewing operations.

[0095] The communication interface module, including Ethernet interface and configurable communication interface, allows the device to connect and communicate with various distribution network automation terminals.

[0096] Built-in battery module ensures that the device can work normally without external power supply

[0097] The intelligent parsing module parses the received data and supports multiple communication protocols and data formats.

[0098] The parameter configuration module allows users to configure and manage the parameters of the communication protocol, and also supports exporting and synchronizing configuration files to the distribution network automation terminal.

[0099] Example 4 is an embodiment of the present invention, which provides a configuration method of an intelligent communication fault diagnosis device for power distribution operation and maintenance. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments.

[0100] First, a test environment including a portable simulation master station and multiple distribution network automation terminals was built. The simulation master station function was configured on the portable simulation master station, which can simulate the behavior of the intelligent communication fault diagnosis master station in distribution operation and maintenance. The simulation master station is configured with high-speed communication protocols through an Ethernet interface, and has a configurable communication interface to support different communication protocols, such as IEC 60870-5-104, DNP3, etc.

[0101] Each distribution network automation terminal is configured with data settings for information body address length, general call telesignaling type, general call telemetry type, remote control type and SOE upload type. The message sending order is set to first synchronize the system time (time synchronization) and then set the heartbeat interval to keep the communication link active and accurate.

[0102] After the connection configuration, connect the simulated master station to the distribution network automation terminal through a shielded twisted pair cable. When conducting communication tests, pay special attention to checking and recording the transmission efficiency and delay time of the message, as well as the response ability of the simulated master station when a fault occurs. Capture fault information through a real-time monitoring system, and make appropriate wiring adjustments to simulate the actual operation of adjusting faults on site.

[0103] The test was divided into five stages, each stage was conducted for different communication protocols and configurations to comprehensively evaluate the wide adaptability and technical advantages of the present invention. The test data was recorded in detail for subsequent analysis and evaluation. The following Table 1 shows the key data collected in the experiment to demonstrate the effect of the present invention:

[0105]

[0106]

[0107] It is obvious from the above table that the present invention has significant advantages in communication efficiency and fault response. The test data of the simulated master station 1 to the simulated master station 5 show that even under different settings and network conditions, the synchronization time delay is maintained between 10 and 15 milliseconds, which is better than the delay of more than 20 milliseconds commonly seen in traditional systems. The heartbeat interval response time also demonstrates efficient network maintenance capabilities, with a response time reduction of about 10% compared to the prior art.

For the purposes of this specification, "computer-readable medium" can be any device that can contain, store, communicate, propagate or transmit a program for use by an instruction execution system, device or apparatus, or in conjunction with such instruction execution systems, devices or apparatuses.
