[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0031] First, to facilitate understanding of the embodiments of this utility model, some terms or nouns involved in this utility model will be explained below:

[0032] Netty is an asynchronous, event-driven network application framework used for rapidly developing high-performance, scalable network server and client programs. Netty supports multiple protocols and encoding / decoding technologies, making network communication simpler and more efficient.

[0033] The IEC 61850 protocol is a standard developed by the International Electrotechnical Commission (IEC) for designing and operating communication networks for power systems. The IEC 61850 protocol defines standards for communication, data models, and device configuration in the field of power system automation. This protocol aims to provide a standardized communication protocol that enables reliable and efficient communication and data exchange between devices in a power system, thereby achieving the intelligence, automation, and interoperability of the power system.

[0034] Long-Term Evolution (LTE) is a fourth-generation (4G) mobile communication technology designed to provide higher data transmission speeds, lower latency, and better network performance. LTE technology employs technologies such as OFDMA (Orthogonal Frequency Division Multiple Access) and MIMO (Multiple-Input Multiple-Output) to support higher data transmission rates, making it suitable for the mobile communications field.

[0035] Code Division Multiple Access (CDMA) is a digital communication technology that uses different code patterns to distinguish signals from different users, enabling parallel transmission between multiple users. CDMA technology can improve spectrum utilization, reduce communication interference, and is suitable for multi-user access and data transmission in mobile communication systems. Figures 1 to 2 As shown in the figure, this utility model embodiment provides a data acquisition system for an energy storage power station, which includes:

[0036] A battery management system 1 is used to collect battery data from an energy storage power station; a communication interface device 2 is used to establish a communication connection between the battery management system 1 and a protocol data acquisition module 3; the protocol data acquisition module 3 is connected to the communication interface device 2 and is used to collect the battery data according to the 61850 protocol format based on the built-in Netty protocol module; a data parsing and processing module 4 is connected to the protocol data acquisition module 3 and is used to convert the collected battery data into standard protocol data supported by a cloud server 5, and send the standard protocol data to the communication interface device 2; the cloud server 5 is connected to the communication interface device 2 and is used to analyze the standard protocol data to obtain the battery data analysis results of the energy storage power station.

[0037] The energy storage power station data acquisition system provided in this embodiment includes at least a battery management system (BMS) 1, a communication interface device 2, a protocol data acquisition module 3, a data parsing and processing module 4, and a cloud server 5. The BMS directly contacts the battery and monitors and collects the battery's operating status data (i.e., battery data), such as voltage, current, and temperature, ensuring real-time and accurate monitoring of battery status and preventing overcharging, over-discharging, or abnormal conditions. The communication interface device 2 acts as a bridge between the BMS and the protocol data acquisition module 3, establishing a stable and reliable communication connection to ensure battery data transmission. The protocol data acquisition module 3, based on a built-in Netty protocol module, can efficiently and concurrently acquire battery data sent by the BMS according to the 61850 protocol format. This improves the efficiency and quality of battery data acquisition, handles a large number of concurrent connections, and ensures the accuracy and timeliness of battery data acquisition even under high load conditions. The data parsing and processing module 4 preprocesses and converts the received raw battery data to ensure that the battery data conforms to the receiving standards of the cloud server 5. This optimizes the data transmission format and ensures that the cloud server 5 can receive and identify the data normally. The cloud server 5 receives standard protocol data from the data parsing and processing module 4, performs in-depth analysis, generates battery data analysis results, and provides the ability to remotely monitor and manage the energy storage power station.

[0038] Optionally, the battery management system 1 can be a level 3 BMS system. The data parsing and processing module 4 can preprocess and convert the received raw battery data based on existing data preprocessing algorithms, transforming the received battery data into data conforming to the 61850 protocol format, so that the cloud server 5 can support and recognize the received data. The cloud server 5 can be a private cloud server 5, which can pre-integrate existing data processing algorithms and models for performing battery health assessments and fault predictions of the energy storage power station based on the received battery-related data (i.e., standard protocol data), and obtaining corresponding battery data analysis results.

[0039] like Figure 1 As shown, the communication interface device 2 includes a remote communication module 21 and a gateway switch 22. The remote communication module 21 establishes a wireless communication connection between the battery management system 1 and the protocol data acquisition module 3; the gateway switch 22 establishes a wired communication connection between the battery management system 1 and the protocol data acquisition module 3. Using this structure, the communication interface device 2 includes both a remote communication module 21 and a gateway switch 22. The use of both modules ensures the diversity and security of battery data transmission. Optionally, the remote communication module 21 and the gateway switch 22 have the same function. The priorities of the remote communication module 21 and the gateway switch 22 can be preset, with the gateway switch 22 having a higher communication priority than the remote communication module 21. When the gateway switch 22 fails, the remote communication module 21 is activated, thereby ensuring the smooth transmission of battery data. The above process can be achieved by setting up an automatic switching device, which may include an infrared sensor, a controller, and a relay. When the gateway switch 22 fails, the infrared sensor detects the fault signal and transmits it to the controller. Upon receiving the signal, the controller triggers the relay to activate the remote communication module 21. This automatic switching device ensures that the remote communication module 21 can be activated promptly when the gateway switch 22 fails, guaranteeing the continuity and stability of communication.

[0040] Optionally, the remote communication module 21 can also be configured to support remote transmission functionality. That is, for situations requiring remote transmission, such as when the distance between the battery management system 1 and the protocol data acquisition module 3 is relatively far, the remote communication module 21 can be used as a bridge for communication and data transmission between the battery management system 1 and the protocol data acquisition module 3. This remote communication module 21 can be a 4G remote communication module. The remote communication module 21 can adopt the Long-Term Evolution (LTE) communication protocol and can also support the Code Division Multiple Access (CDMA) communication protocol.

[0041] like Figure 1 As shown, the energy storage power station data acquisition system further includes a one-way isolation gate 6, wherein the one-way isolation gate 6 is disposed between the battery management system 1 and the communication interface device 2. By adopting the above structure and setting a one-way isolation network between the battery management system 1 and the communication interface device 2, the data of the battery management system 1 can be securely isolated from the outside world, thereby improving the operational safety of the battery management system 1.

[0042] It should be noted that the one-way isolation gateway 6 plays a role in data security protection between the battery management system 1 and the communication interface device 2. It prevents unauthorized access from the communication interface device 2 to intrude into the battery management system 1, thus preventing unauthorized data transmission. Through the one-way isolation gateway 6, data is only allowed to be transmitted from the battery management system 1 to the communication interface device 2, but not from the communication interface device 2 to the battery management system 1, ensuring the security of data transmission and thereby protecting the normal operation and data security of the battery management system 1. Figure 1 As shown, the communication interface device 2 establishes a communication connection between the battery management system 1 and the protocol data acquisition module 3 through the transmission control protocol.

[0043] With the above structure, the communication interface device 2 acts as a bridge between the battery management system 1 and the protocol data acquisition module 3, establishing a stable and reliable communication connection through the Transmission Control Protocol (TCP) to ensure data transmission. By defining the communication interface device 2 to transmit data based on the TCP protocol, efficient and uninterrupted data transmission can be achieved, maintaining stable communication even in complex network environments and reducing the risk of data packet loss or transmission delay.

[0044] like Figure 1As shown, the unidirectional isolation gate 6 includes a high-speed isolation device. Using this structure, the high-speed isolation device provides physical layer isolation, ensuring that battery data can only flow from the battery management system 1 to the communication interface device 2, and not in the reverse direction, thereby protecting the normal operation and data security of the battery management system 1.

[0045] It should be noted that because high-speed isolation devices use physical isolation, this physical isolation is more secure than logical isolation methods such as firewalls, as the data link is actually disconnected, reducing potential security vulnerabilities. High-speed isolation devices can also filter and process transmitted battery data, allowing only data of specific formats or types to pass through, further enhancing security.

[0046] like Figure 1 As shown, the protocol data acquisition module 3 and the data parsing and processing module 4 are integrated in the acquisition server 7. Using this structure, integrating the protocol data acquisition module 3 and the data parsing and processing module 4 enables the integration of data acquisition and parsing processing functions, simplifying the system architecture and improving overall system performance. This not only reduces data transmission and processing latency, improving the efficiency of data acquisition and processing, but also simplifies system management and maintenance processes, reducing unnecessary deployment and configuration work.

[0047] like Figure 1 As shown, the acquisition server 7 further includes an encryption device 8, connected to the data parsing and processing module 4 and the communication interface device 2, used to encrypt the standard protocol data and send the encrypted standard protocol data to the communication interface device 2. With the above structure, the acquisition server 7 includes an encryption device 8. After encrypting the standard protocol data through this encryption device 8, it is sent to the cloud server 5 via the communication interface device 2, thereby further improving the security and integrity of battery data transmission.

[0048] like Figure 1 As shown, the energy storage power station data acquisition system also includes a monitoring device 9, connected to the cloud server 5, used to display the battery data analysis results from the cloud server 5. Using the above structure, by setting up the monitoring device 9 to receive and display the battery data analysis results, users can monitor battery status and performance, better understand the working condition and monitoring status of the batteries in the energy storage power station, promptly identify problems and take corresponding measures, and improve the troubleshooting efficiency of the energy storage power station.

[0049] like Figure 1As shown, the energy storage power station data acquisition system also includes an alarm device 10, connected to the monitoring device 9, used to issue alarms based on abnormal data in the battery data analysis results. With this structure, the alarm device 10 can issue alarms based on abnormal data in the battery data analysis results, reminding users of potential problems with the battery system in the energy storage power station, improving users' awareness and response speed to abnormal situations. This helps users discover potential problems with the battery system in advance, take timely measures for repair or maintenance, and avoid more serious accidents.

[0050] Optionally, the alarm device 10 can be an audible and visual alarm.

[0051] like Figure 1 As shown, the energy storage power station data acquisition system further includes: multiple sensor devices 11 connected to the communication interface device 2, used for data acquisition and sending the acquired data to the communication interface device 2; wherein, the multiple sensor devices 11 include at least a vibration sensor, a sound sensor, and a smoke sensor. The vibration sensor is used to collect vibration data of the energy storage power station, the sound sensor is used to collect sound data within the energy storage power station, and the smoke sensor is used to collect smoke data within the energy storage power station. With the above structure, the sensor devices, including vibration sensors, sound sensors, and smoke sensors, are used to collect vibration, sound, and smoke data from the energy storage power station. The data collected by the sensor devices can monitor and analyze the internal state and environmental conditions of the energy storage power station, promptly detect abnormalities, and provide early warnings. For example, vibration sensors can detect equipment vibration, sound sensors can detect abnormal noise, and smoke sensors can detect smoke, thereby providing early warnings of potential safety risks.

[0052] It should be noted that by setting up multiple sensor devices 11 and connecting them to the communication interface device 2, the number of required hardware devices can be reduced by using a single communication interface device 2, thereby reducing equipment and maintenance costs. A single communication interface device 2 can centrally process and forward data from all sensors, making the entire system architecture simpler and easier to manage and upgrade. Through centralized data acquisition, data preprocessing, filtering, and conversion can be performed more effectively, ensuring the quality of data uploaded to the cloud server 5.

[0053] Optionally, vibration sensors can detect the vibration of the battery compartment or battery pack in the energy storage power station. This is very useful for preventing equipment failures, detecting abnormal operations (such as impacts and drops), and monitoring the physical condition of the batteries (such as loosening). Sound sensors can be used to detect abnormal sounds emitted by the battery or battery management system 1 during operation, such as arcing sounds and explosion sounds. These sounds are often precursors to battery failures or abnormalities. Sound sensors can provide early warnings and assist in fault diagnosis and maintenance. The application of smoke sensors in the battery management system 1 is mainly to detect smoke in the battery or battery environment. This is a common signal of battery overheating, short circuits, or fires. Smoke sensors can detect fire hazards in a timely manner, activate fire protection systems, or take other safety measures to protect the safety of personnel and equipment.

[0054] Based on the above embodiments and optional embodiments, this utility model proposes an optional implementation method for an energy storage power station data acquisition system, such as... Figure 1 As shown, the data acquisition system for this energy storage power station includes:

[0056] Battery Management System 1 is responsible for monitoring the status of Battery Management System 1 in the energy storage power station and collecting various battery data, including voltage, current, and temperature.

[0057] The one-way isolation gate 6 is connected to the battery management system 1 and is used to isolate the data stored in the battery management system 1 from the outside world, so as to ensure the data security of the battery management system 1.

A stable and reliable communication connection is established through TCP protocol so that the battery data collected by battery management system 1 can be transmitted to acquisition server 7 efficiently and without interruption.

[0059] The acquisition server 7 includes a protocol data acquisition module 3 and a data parsing and processing module 4, wherein:

[0060] The protocol data acquisition module 3 is based on the built-in Netty protocol module, which can acquire battery data sent by the battery management system 1 in a high-concurrency and high-efficiency manner according to the 61850 protocol format;

[0061] The data parsing and processing module 4 is connected to the protocol data acquisition module 3. It is used to parse and convert the acquired battery data to obtain the standard protocol data supported by the cloud server 5, and send the standard protocol data to the gateway switch 22.

[0062] Gateway switch 22 is also used to send standard protocol data to cloud server 5;

[0063] Cloud server 5, connected to gateway switch 22, is used to analyze the received standard protocol data to obtain the battery data analysis results of the energy storage power station;

[0064] The remote communication module 21 is used to establish and maintain the communication connection between the acquisition server 7 and the battery management system 1 when there is a need for remote data transmission or when the switch is not working, so as to ensure efficient and stable data transmission. The function of the remote communication module 21 is the same as that of the gateway switch 22, and will not be described again here.

[0069] S4, the battery management system 1 collects battery data sent by the battery management system 1 through the protocol data acquisition module 3 based on the built-in Netty protocol module, and converts the data into standard protocol data supported by the cloud server 5 through the data parsing and processing module 4, and generates a standard format file based on the standard protocol data.

[0070] S5, establishes a TCP communication channel between cloud server 5 and acquisition server 7 through gateway switch 22. When gateway switch 22 fails or there is a need for remote transmission, remote communication module 21 serves as the transmission channel.

[0071] S6, the acquisition server 7 and gateway switch 22 serve as a communication channel to transmit the obtained standard format files to the cloud server 5.

[0072] The energy storage power station data acquisition system in this embodiment utilizes Netty communication technology to achieve efficient data transmission between the acquisition server 7 and the battery management system 1. Netty's powerful single-machine million-concurrency processing capability ensures the efficiency and stability of data transmission. A unidirectional isolation gateway 6 achieves data isolation between internal and external security zones, as well as between high and low security zones, ensuring data security.
