[0055] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it can be understood by those skilled in the art that in the embodiments of the present invention, many technical details are proposed in order to enable readers to better understand the present invention. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present invention can also be implemented. The division of the following embodiments is for the convenience of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined and referenced with each other without contradiction.

[0056] Electrochemical Energy Storage System (ESS) is a system that uses electrochemical reactions to store and release electrical energy. It converts electrical energy into chemical energy through batteries (such as lithium-ion batteries, lead-acid batteries, sodium-sulfur batteries, etc.) and converts chemical energy into electrical energy for output when needed. The electrochemical energy storage system contains multiple devices, such as the battery management system (BMS): monitors and manages the status of the battery pack, the power conversion system (PCS): realizes the conversion between DC and AC, the energy management system (EMS): monitors and schedules the operation of the entire energy storage system, etc. The communication configuration between them is labor-intensive and complex. The existing communication system configuration usually follows the following steps:

[0057] 1. Determine the communication requirements between each subsystem, including telemetry, telesignaling, and remote control points.

[0058] 2. Manually configure communication protocol parameters, such as Modbus register addresses or IEC 61850 models, IEC104 models, according to device specifications and technical manuals.

[0059] 3. Physical connection and communication line establishment by on-site engineers.

[0060] 4. Perform manual testing of points to verify data accuracy and communication reliability.

[0061] 5. Record and update configuration information to form a communication network diagram of the site

[0062] The communication interface in this application is the communication point, which refers to the logical or physical location in the communication system used to transmit and receive specific data or control instructions. Points are usually associated with specific equipment or sensors, and are used to identify and locate specific data sources or control targets. Each point usually corresponds to a specific data source or control target, such as a sensor, switch, controller, etc. It is a data point of communication. Generally, the power industry is divided into telesignaling, telemetering, teleadjustment, and telecontrol. For example:

[0063] Telemetry point: used to transmit the telemetry data of the equipment, such as voltage, current, temperature, power, etc.;

[0064] Remote signal point: used to transmit the remote signal status of the equipment, such as switch status, alarm status, etc.

[0065] Remote control point: used to transmit remote control instructions of equipment, such as start, stop, adjust, etc.

[0066] Each device in an electrochemical energy storage system usually corresponds to multiple communication interfaces (points) for transmitting different data types (such as telemetry, telesignaling, remote control, etc.).

[0067] Modbus is a communication protocol developed by Modicon (Modular Digital Controller) in 1979, originally used for communication between its programmable logic controllers. Due to its simplicity, openness and ease of implementation, Modbus has gradually become a widely used communication protocol in the field of industrial automation.

[0068] IEC 61850 is a standard developed by the International Electrotechnical Commission (IEC) specifically for communication in substation automation systems. It defines the communication protocol and data model between various devices in a substation (such as circuit breakers, protection devices, measuring equipment, etc.).

[0069] IEC 104 is part of the IEC 60870-5 series of standards and is mainly used for telecontrol communications in power systems. It is a communication protocol based on TCP / IP (Transmission Control Protocol / Internet Protocol) and is used to achieve data exchange between the dispatch center and substations, power plants and other equipment.

[0070] The existing methods have the following problems:

[0071] 1. Low configuration efficiency: Due to reliance on manual configuration and testing, the configuration process is time-consuming and prone to errors.

[0072] 2. Poor scalability: As the scale of power plants increases, manually managing the communication network becomes complicated and difficult to adapt to system expansion.

[0073] 3. High maintenance cost: Manual configuration and testing require a large number of on-site engineers, increasing labor costs.

[0074] 4. Data consistency issues: Manually recording and updating configuration information is prone to omissions or errors, resulting in inconsistent data.

[0075] 5. Lack of intelligence: Existing methods cannot achieve automated point recommendation and configuration optimization and rely on engineer experience.

[0076] In addition, when processing large-scale data, existing technologies lack effective data analysis and processing capabilities, making it difficult to achieve in-depth insights into equipment status and operating trends, resulting in the inability to perform predictive maintenance and optimize decision-making. These problems limit the reliability and intelligence level of the communication system of electrochemical energy storage power stations.

[0077] This application develops a middleware for rapid configuration of point tables, which realizes automated device identification, point scanning, intelligent classification, automatic numbering, and configuration optimization, greatly reducing manual intervention and lowering the configuration error rate.

[0078] In this application, the communication interface refers to the communication point.

[0079] Reference Figure 1 , shows a flow chart of the steps of a communication interface matching method for an electrochemical energy storage system provided by an embodiment of the present invention, which may specifically include the following steps:

[0080] Step 101, identifying device information of a device connected to the electrochemical energy storage system; the device information includes the model, manufacturer, and number of communication interfaces of the device.

[0081] This application develops a middleware and uses the middleware to perform automated device identification. Develop device fingerprint technology in the middleware. Use device fingerprint technology to quickly identify the model and manufacturer of the connected device. Among them, device fingerprint technology is a technology that identifies and tracks devices by analyzing the unique characteristics of the device. Its core is to generate a unique identifier (i.e., "fingerprint") by analyzing the hardware and software characteristics of the device, thereby identifying the model and manufacturer of the device.

[0082] A point database containing the models, manufacturers, and corresponding number of points of various devices is pre-built in the middleware. When the device is connected to the electrochemical energy storage system, the middleware will automatically capture the communication data packet of the device, extract the device's unique identifier (such as MAC address) and communication protocol features (such as frame header, frame tail, data format, etc.) from the data packet, match the extracted features with the pre-built point database, and quickly identify the model, manufacturer, and number of points of the device.

[0083] Step 102, scanning and identifying the communication interface type of the device according to the device information; the communication interface type includes at least telemetry, remote control, and remote communication.

[0084] The middleware is integrated with artificial intelligence algorithms. After obtaining the number of points corresponding to the equipment, the artificial intelligence algorithms can be used to automatically scan and identify the type of points of the equipment (telemetry, remote control, remote communication). That is, determine what type of points all the points of the equipment are.

[0085] Specifically, a large amount of telemetry, remote control and telesignaling point data can be collected, the type of each point can be marked, and a machine learning model (such as random forest, support vector machine) can be used to train a classification model using the marked data set. The trained classification model can be used to identify the point type.

[0086] Step 103: Acquire the communication protocol for communication between the devices, and extract the communication interface metadata of the device according to the device model and the communication protocol.

[0087] A communication protocol parsing engine is developed in the middleware, which supports plug-in communication protocol adaptation and parsing of multiple communication protocols. Users can expand new protocols through plug-ins. If the communication protocol of the device is relatively special, or there is a problem with the encoding of the communication protocol, it can be identified through the engine to ensure that the connection is carried out in accordance with the communication protocol agreed upon between the devices, and there will be no communication anomalies, data anomalies and other problems at the points.

[0088] Each device generally supports multiple communication protocols, and the communication protocols are mainly selected manually. Generally, a device will support several communication protocols, and the number of communication protocols is relatively limited, so manual selection is sufficient.

[0089] After determining the device model, determine the communication protocol corresponding to the device, load the corresponding communication protocol plug-in according to the communication protocol used by the device, parse the device's communication data packet, and then use artificial intelligence algorithms to extract point bit metadata (register address, data type, unit, etc.) from the parsed data packet.

[0090] A big data cloud platform is also built in the middleware, which includes data collection layer, data processing layer, data storage layer and application service layer. Data collection and integration: Centrally store point metadata from different devices and systems.

[0091] The point-bit metadata (register address, data type, unit, etc.) extracted from the parsed data packets using artificial intelligence algorithms is stored in the cloud platform.

[0092] Step 104: obtain a preset communication interface numbering rule, number the communication interfaces according to the communication interface numbering rule, and generate a communication interface table.

[0093] The middleware has a preset point numbering rule library, which contains various point numbering rules, such as:

[0094] Numbering rule format: equipment number-function number-address number-sequence number;

[0095] Device number: identifies the device or module of the point; Function number: identifies the function type of the point (such as telemetry, remote control, remote communication); Address number: identifies the address of the point (such as register address); Sequence number: identifies the sequence of the point (such as 1, 2, 3...).

[0096] Example: BMS-01-40001-001: indicates the first telemetry point of the battery management system (BMS), with the address 40001;

[0097] PCS-02-50001-002: indicates the second remote control point of the power conversion system (PCS), with the address 50001.

[0098] After determining the point numbering rule, you can number the points of the equipment according to the point numbering rule and generate a point table. Generally, the point table is an Excel table, which can be numbered in order.

[0099] Step 105: Match the communication interface between the devices according to the communication interface table and the communication protocol.

[0100] After obtaining the point table of the equipment, the points between the equipment can be matched according to the point numbers in the point table.

[0101] Point matching is a key step to ensure that devices can communicate correctly. Specifically, the points of device A (sender) need to be matched one-to-one with the points of device B (receiver), ensuring that the point names, numbers, sequences, and communication protocols are consistent.

[0102] Through the above method, through device fingerprint technology and communication protocol adapter, the middleware can automatically identify connected devices and collect necessary point metadata, which is the basis for achieving rapid configuration.

[0103] In an embodiment of the present invention, by identifying the device information of the device connected to the electrochemical energy storage system; the device information includes the model, manufacturer, and number of communication interfaces of the device; according to the device information, scan and identify the type of communication interface of the device; the communication interface type includes at least telemetry, remote control, and remote signaling; obtain the communication protocol for communication between devices, extract the communication interface metadata of the device according to the device model and communication protocol; obtain the preset communication interface numbering rule, number the communication interface according to the communication interface numbering rule, and generate a communication interface table; match the communication interface between devices according to the communication interface table and the communication protocol. The embodiment of the present invention greatly reduces the workload of manual configuration, shortens the configuration cycle, and improves the overall configuration efficiency through automated device identification and point data collection; and automated point scanning reduces configuration errors caused by human factors and improves the accuracy of point configuration.

[0104] In an optional embodiment of the present invention, step 101 further includes the following steps:

[0105] S1011, preset a communication interface database; the communication interface database includes device information of at least one device;

[0106] S1012, matching device information of the device from the communication interface database;

[0107] S1013: If the matching fails, the device information of the device is entered into the communication interface database.

[0108] A point database containing the models, manufacturers, and corresponding number of points of various devices is pre-built in the middleware. When the device is connected to the electrochemical energy storage system, the middleware will automatically capture the communication data packet of the device, extract the unique identifier of the device (such as MAC address) and communication protocol features (such as frame header, frame tail, data format, etc.) from the data packet, and match the extracted features with the pre-built point database. If the match fails, it means that the device is not in the database, then it is necessary to add a new entry to record the model, manufacturer and corresponding number of points of the device in the point database to expand the point database.

[0109] In an optional embodiment of the present invention, step 103 further includes the following sub-steps:

[0110] S1031, using a protocol plug-in corresponding to the communication protocol to parse a communication data packet of the device;

[0111] S1032: Extract the communication interface metadata of the device from the parsed communication data packet according to the device model.

[0112] After determining the device model, determine the communication protocol corresponding to the device, load the corresponding protocol plug-in according to the communication protocol used by the device, parse the device's communication data packet, and then use artificial intelligence algorithms to extract point bit metadata (register address, data type, unit, etc.) from the parsed data packet.

[0113] Specifically, protocol plug-ins can be used to parse data packets, extract information such as register addresses and data types, and artificial intelligence algorithms (such as machine learning and deep learning) can be used to analyze data packets and extract metadata.

[0114] In an optional embodiment of the present invention, step 103 further includes the following sub-steps:

[0115] S103-1, determining a data object transmitted by the communication interface according to the communication interface metadata;

[0116] S103-2, classify the communication interface according to the data object to obtain a classification result.

[0117] Classify points according to the specific devices or functional modules they correspond to in the equipment system, that is, classify them according to the dimensions of the objects associated with the data, for example: points in the battery management system:

[0118] Module voltage point: corresponds to the voltage information of the battery module;

[0119] Cell voltage point: corresponds to the voltage information of the cell in the battery module;

[0120] Points in the power conversion system:

[0121] Input voltage point: voltage information corresponding to the input terminal;

[0122] Output current point: corresponding to the current information of the output end;

[0123] According to the point metadata, the data object transmitted by the point can be determined, that is, whether the point transmits voltage or current, whose voltage it is, etc. It focuses more on the specific meaning and associated objects of the point in the system.

[0124] Specifically, machine learning algorithms can be used to intelligently classify points, such as classification algorithms (such as random forest, SVM (support vector machine), KNN (K nearest neighbor)) can be used to classify points. Clustering algorithms (such as K-Means (K mean), DBSCAN (Density-Based Spatial Clustering of Applications with Noise, density-based clustering algorithm)) can be used to group points and identify similar points. Association rule mining (such as Apriori algorithm) can be used to analyze the association relationship between points.

[0125] Specifically, the collected point metadata is processed to extract device features, point features and associated features, and construct feature vectors. The classification model is trained (a large number of point samples are collected and the equipment or devices corresponding to each point are labeled) using the labeled data (selecting a suitable machine learning algorithm), and the points are intelligently classified using the trained model to obtain the classification results.

[0126] In an optional embodiment of the present invention, step 104 further includes the following sub-steps:

[0127] S1041, determining a communication interface numbering rule library according to the communication interface metadata of the device and the classification result of the communication interface.

[0128] When generating point numbering rules, the following principles should be followed: each point number must be unique to avoid duplication; the numbering rules should support the expansion of new points in the future; the numbers should have a certain readability to facilitate understanding and maintenance; the numbers can reflect the hierarchical structure of the points (such as equipment, modules, functions).

[0129] When generating point numbering rules, not only the point metadata should be considered, but also the classification results based on the specific devices or functional modules corresponding to the points in the equipment system, that is, the dimensions of the objects associated with the data.

[0130] Common point numbering rules: device number (identifies the device or module of the point), function number (identifies the function type of the point (such as telemetry, remote control, remote signaling)), address number (identifies the address of the point (such as register address)), sequence number (identifies the order of the point (such as 1, 2, 3...)), etc.

[0131] Let's take an example to illustrate:

[0132] Point numbering rule format: equipment number-function number-address number-sequence number;

[0133] BMS-01-40001-001: indicates the first telemetry point of the battery management system (BMS), with the address 40001;

[0134] PCS-02-50001-002: indicates the second remote control point of the power conversion system (PCS), with the address 50001.

[0135] S1042, obtaining a communication link between the devices;

[0136] S1043, identifying the data flow of a device connected to the electrochemical energy storage system;

[0137] S1044: Determine the communication level of the device in the communication link according to the data flow direction.

[0138] The communication link between devices is the data transmission path. For example, the voltage data of your battery cell may be collected by the BMS, and then sent to the PCS, then to the EMS system, and then to the centralized control system. The communication link is from BMS to PCS to EMS to the centralized control system. After determining the communication link, determine the communication level of the communicating devices (assuming that devices A and B are communicating) in the entire communication link.

[0139] S1045, selecting a communication interface numbering rule from the communication interface numbering rule library according to the communication level;

[0140] S1046, numbering the communication interfaces of the device according to the communication interface rule to generate a communication interface table;

[0141] Set up different levels in advance, and then each level can have a point numbering rule to form a point numbering rule library.

[0142] After determining the communication level of the device, you can select the appropriate point numbering rule from the point numbering rule library according to the communication level. According to the selected point numbering rule, you can number the points of the device and finally generate a point table.

[0143] For example: the selected point numbering rule is: device number-function number-address number-sequence number,

[0144] Assuming the current device is A, the number is: A-01-40001-001: indicates the first telemetry point of device A, with address 40001.

[0145] In addition, the point numbering rule can also be selected according to the communication protocol between devices. For example, if device A and device B use the Modbus protocol, the point numbering rule can be based on the Modbus register address; if device A and device B use the OPC UA (OPC Unified Architecture) protocol, the point numbering rule can be based on the OPC UA node ID.

[0146] Sort and number the points according to the point numbering rules to ensure that the point numbers and order of device A and device B are consistent.

[0147] The point table may include the point number (unique identifier, such as A-01-40001-001), equipment number (such as BMS, PCS, EMS), function type (such as telemetry, remote control, remote signaling), address number (such as register address), and point name (such as battery voltage, temperature sensor, etc.).

[0148] When performing point matching, the matching rules are:

[0149] The point name of device A is the same as the point name of device B;

[0150] The point number of device A is the same as the point number of device B;

[0151] The point address of device A is consistent with the point address of device B;

[0152] The communication protocols of device A and device B are consistent;

[0153] Point matching is performed through the point table to ensure that the points of device A and device B correspond one to one and that the communication protocols are consistent, thereby achieving point matching of device A and device B and ensuring smooth communication and accurate data transmission.

[0154] It should be noted that the communication between devices, that is, data transmission, will be encrypted and securely transmitted to ensure the security of data during transmission. The SSL (Secure Sockets Layer) / TLS (Transport Layer Security) protocol can be used to encrypt data transmission to prevent data from being stolen during transmission, and to encrypt data stored in the database or data lake to prevent data leakage. Strict access control is implemented to ensure that only authorized users can access sensitive data. User access behavior can also be recorded and audit logs can be generated for easy tracking and analysis.

[0155] In an optional embodiment of the present invention, after S1045, the following sub-steps are also included:

[0156] S1045-1, obtaining real-time operation data of the device and historical configuration records of the device;

[0157] S1045-2: Adjust the communication interface numbering rule according to the real-time operation data and the historical configuration record.

[0158] The real-time operation data of the points during operation is collected through the big data cloud platform, and the operation status of the points is recorded, such as communication delay, data loss rate, communication success rate, etc. Real-time operation data refers to the specific values ​​collected or transmitted in real time during the operation of a certain point, which is dynamic and changes over time.

[0159] Obtain the historical configuration records of the equipment (equipment model, communication protocol, point metadata, etc.) from the big data cloud platform, and extract the point numbering rules from the historical configuration records. Analyze the communication problems in the historical configuration records, such as communication failure, data loss, etc., to find out the deficiencies of the point numbering rules.

[0160] Based on real-time operation data and historical configuration records, the point numbering rules are dynamically adjusted to improve communication efficiency and stability.

[0161] In an optional embodiment of the present invention, after S1045, the following sub-steps are also included:

[0162] S1045-11, reserving a candidate communication interface number in the communication interface numbering rule;

[0163] S1045-12: If the communication interface of the device is increased, the increased communication interface is numbered using the candidate communication interface number.

[0164] The point numbering rules should support the expansion of new points in the future to avoid numbering conflicts caused by new points. This can be achieved by reserving a certain amount of numbering space in the numbering rules.

[0165] Let's take an example to illustrate:

[0166] Equipment number: BMS, PCS, EMS;

[0167] Function number: 01 (telemetry), 02 (remote control), 03 (remote communication);

[0168] Address number: 40001, 40002, 40003;

[0169] Sequential numbers: 001, 002, 003;

[0170] Reserved range: Sequential numbers from 001 to 999, with 900 to 999 reserved as backup points.

[0171] In an optional embodiment of the present invention, step 105 may further include the following steps:

[0172] S1051, matching the communication interfaces between the devices according to the communication interface numbers;

[0173] S1052: Enable the devices to communicate with each other according to the communication protocol and the matched communication interface.

[0174] Specifically, the point table may include point number (unique identifier, such as A-01-40001-001), equipment number (such as BMS, PCS, EMS), function type (such as telemetry, remote control, remote signal), address number (such as register address), point name (such as battery voltage, temperature sensor, etc.), etc.

[0175] When performing point matching, the matching rules are:

[0176] The point name of device A is the same as the point name of device B;

[0177] The point number of device A is the same as the point number of device B;

[0178] The point address of device A is consistent with the point address of device B;

[0179] The communication protocols of device A and device B are consistent;

[0180] Point matching is performed through the point table to ensure that the points of device A and device B correspond one to one and that the communication protocols are consistent, thereby achieving point matching between device A and device B and ensuring smooth communication between devices and accurate data transmission.

[0181] After completing the point matching between devices, the middleware will automatically perform point communication tests to ensure normal communication.

[0182] In an optional embodiment of the present invention, the following steps may also be included:

[0183] S1, monitor the operation data of the device in real time to detect whether the device is abnormal or fails;

[0184] S2: If the device is abnormal or fails, a corresponding adjustment plan is automatically adopted.

[0185] The middleware integrates anomaly detection and self-healing mechanisms. Anomaly detection monitors the system's operating status in real time and promptly detects configuration errors or communication failures. After detecting an anomaly, the self-healing mechanism automatically adjusts the configuration or takes other measures to ensure the stable operation of the system.

[0186] Through the communication protocol parsing engine of the middleware and the data collection layer in the big data cloud platform, the operating status and communication data of the equipment are monitored in real time, and anomaly detection rules are defined, such as data anomalies, communication interruptions, configuration conflicts, etc. During the monitoring process, whether there are abnormal situations is automatically detected. When a configuration error or communication failure is detected, the configuration plan is automatically adjusted to solve the abnormal problem. When a device failure is detected, the device is automatically restarted to restore the normal operation of the system. When a communication interruption is detected, the communication connection is automatically restored to ensure normal data transmission. After the automatic adjustment, the adjustment results can be displayed to the user, and the user can confirm or adjust manually.

[0187] The middleware is designed with a user interface and a graphical programming interface, which provides drag-and-drop operations to customize point configuration. Specifically, graphical components such as point icons, device icons, and connection lines are designed, and users can combine these components into configuration solutions through drag-and-drop operations.

[0188] An intuitive user interface is designed to display the adjustment results to users through the user interface, thus improving the user experience.

[0189] Through the above-mentioned embodiments of the invention, through automated equipment identification and point data collection, the workload of manual configuration is greatly reduced, the configuration cycle is shortened, and the overall configuration efficiency is improved; and automated point scanning and intelligent classification reduce configuration errors caused by human factors and improve the accuracy of point configuration; the design of the middleware and cloud platform allows the system to easily adapt to the expansion of the power station scale without large-scale changes to the existing configuration process; the graphical user interface provides an intuitive operation method, allowing users to manage and adjust point configurations more conveniently. In addition, the integrated anomaly detection and self-healing mechanism can monitor the configuration and communication status in real time, respond quickly to abnormal situations, and reduce system downtime; data encryption and access control mechanisms enhance the data security of the system and protect key information from unauthorized access.
