[0021] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0022] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0023] First, to facilitate understanding of the embodiments of the present invention, some of the terms or nouns involved in the present invention are explained below:

[0024] The Transmission Control Protocol (TCP) is a connection-oriented, reliable, byte-stream-based transmission protocol commonly used in network communications. The TCP communication channel is a communication connection established based on the TCP protocol, which is a bidirectional channel for transmitting data on the network.

[0025] A gateway switch is a network device used to connect communications between different networks. It can convert and route data between different network protocols to achieve data transmission between different networks.

[0026] The asynchronous event-driven network communication framework (Netty) is used to quickly develop high-performance, scalable network application interfaces and build network transmission frameworks. It provides a simple and powerful application programming interface that enables developers to easily create various types of network applications, such as clients and servers.

[0027] like Figure 1 As shown, an embodiment of the present invention provides a battery data transmission system, the battery data transmission system comprising:

[0028] like Figure 1 As shown, Figure 1 The figure is a schematic diagram of the structure of a battery data transmission system according to an embodiment of the present invention. The battery data transmission system includes: a battery management module 1 for collecting battery data from an energy storage power station; a collection server 2, connected to the battery management module 1 via a wireless network, for receiving and storing the battery data; a Netty communication module 3, disposed between the battery management module 1 and the collection server 2, connected to the battery management module 1 via a wireless network, for establishing a transmission control protocol channel between the battery management module 1 and the collection server 2, and transmitting the battery data to the collection server 2 based on the transmission control protocol channel; and an 104 protocol module 4, disposed between the Netty communication module 3 and the collection server 2, connected to the Netty communication module 3 via an RS485 interface, for converting the battery data into transmission data in the 104 protocol format.

[0029] The battery data transmission system provided in this embodiment is used to collect battery data in an energy storage power station based on a battery management module 1. The energy storage power station contains multiple battery blocks, each of which outputs power and inputs power during charging. Data such as voltage and current on the multiple battery blocks is collected to monitor the safety of the battery blocks in the energy storage power station in real time, effectively preventing power hazards in the energy storage power station from being discovered in a timely manner. Furthermore, temperature information near the multiple battery blocks can be collected. Since battery blocks release heat during charging and discharging, excessively high temperatures between multiple battery blocks can cause spontaneous combustion of the battery blocks. Collecting temperature information near the battery blocks in the energy storage power station effectively achieves the effect of real-time monitoring of the safety of the energy storage power station.

[0030] Optionally, the above-mentioned collected battery data is transmitted to the collection server 2 through the Netty communication module 3, wherein the Netty communication module 3 can specifically construct a network communication framework (Netty), and the Netty framework can provide high-performance network programming capabilities, which can achieve fast and reliable data transmission. The Netty communication module 3 can establish a Transmission Control Protocol channel (TCP channel) between the battery management module 1 and the collection server 2 to achieve efficient and stable transmission of battery data. Based on the 104 protocol preset in the 104 protocol module 4, the battery data is transmitted to the collection server 2, and the collection server 2 stores the battery data for subsequent real-time detection of the battery data, which can achieve the effect of real-time monitoring of the safety of the energy storage power station.

[0031] Specifically, based on the 104 protocol module 4, the battery data can be converted into transmission data that conforms to the 104 protocol format at the beginning of battery data transmission, that is, at the initial end of the network communication framework constructed by the Netty communication module 3. Data that conforms to the 104 protocol format can effectively reduce the data loss rate during transmission and ensure data transmission security. The transmission data that conforms to the 104 protocol format is transmitted to the collection server 2, and then the collection server 2 converts the data into data that the collection server 2 can recognize, effectively realizing the fast, efficient, stable and secure transmission of battery data.

[0032] like Figure 1 As shown, the battery data transmission system also includes: a gateway switch 5, which is arranged between the battery management module 1 and the Netty communication module 3, connected to the battery management module 1 through a wireless network, and connected to the Netty communication module 3 through an RS485 interface, and is used to convert battery data from a wireless network communication mode to an RS485 interface communication mode.

[0033] With the above structure, the energy storage power station is far away from the monitoring main console (i.e., the acquisition server 2), and it is necessary to use a wireless network to transmit the above battery data to the acquisition server 2. The Netty communication module 3 is established between the energy storage power station and the main console, and there may be conversion between battery data and network switching. During the network switching process, by setting a gateway switch 5, the different networks in the above network switching process are connected based on the gateway switch 5, so that the data between different networks are converted and routed to realize data transmission between different networks.

[0034] like Figure 1 As shown, the battery data transmission system further includes: a network switch 6, which is arranged between the battery management module 1 and the gateway switch 5, and is used to transmit the battery data from the battery management module 1 to the gateway switch 5 in a unidirectional manner.

[0035] With the above structure, the gateway switch 5 can realize the conversion and routing of battery data between multiple different networks. Since the battery data needs to be transmitted to the acquisition server 2 after conversion, in order to avoid the battery data being converted multiple times at the gateway switch 5 and then returned to the battery management module 1, a network switch 6 is set between the gateway switch 5 and the battery management module 1. The network switch 6 is a unidirectional network gateway, which enables the battery data to be transmitted unidirectionally from the battery management module 1 to the gateway switch 5, effectively realizing the transmission of the battery data to the acquisition server 2.

[0036] like Figure 1As shown, the battery data transmission system also includes: a data processing module 7, which is connected to the acquisition server 2, and is used to obtain the transmission data received by the acquisition server 2, filter the transmission data, convert the filtered transmission data into digital data that can be recognized by the acquisition server 2, and transmit the digital data to the acquisition server 2.

[0037] Using the above structure, the acquisition server 2 receives the transmission data in the protocol format 104 and needs to convert it into digital data that can be recognized by the server (processor or computer device) to enable subsequent real-time monitoring of the battery data, thereby achieving monitoring of the energy storage power station. Specifically, the data processing module 7 is connected to the acquisition server 2, and the data processing module 7 is used to convert the transmission data into digital data that can be recognized by the acquisition server 2. The data processing module 7 can also be integrated into the acquisition server 2, that is, the acquisition server 2 includes two parts, one with storage function and the other with data conversion function. This effectively achieves stable transmission of battery data, thereby effectively achieving the reception and storage of battery data.

[0038] like Figure 1 As shown, the battery data transmission system also includes: a cloud server 8, which is connected to the collection server 2 through a Netty communication module 3; the collection server 2 is also used to transmit the received digital data to the cloud server 8.

[0039] Using the above structure, the acquisition server 2 converts the battery data into digital data for storage and transmits the digital data to the cloud server 8 via the Netty communication module 3. Cloud server 8, acting as a processor, can perform real-time monitoring of the digital data to monitor the safety of the energy storage power station. Cloud server 8 can also integrate the digital data into a time-based comparison table or line chart for subsequent review by energy storage power station maintenance personnel.

[0040] like Figure 1 As shown, the battery data transmission system further includes: a display module 9 connected to the cloud server 8 for displaying digital data.

[0041] With the above structure, the cloud server 8 integrates the digital data to form a time-based comparison table of the battery data. The cloud server 8 is connected to the display module 9 to display the above-formed comparison table for the maintenance staff of the energy storage power station to view. The display module 9 can be a display screen.

[0042] like Figure 1As shown, the battery data transmission system also includes: a transmission detection module 10, which is connected to the acquisition server 2 and is used to detect erroneous data in the transmitted data; an alarm module 11, which is connected to the transmission detection module 10; the transmission detection module 10 is also used to transmit erroneous data to the alarm module 11; the alarm module 11 is also used to issue an alarm when erroneous data is received.

[0043] With the above structure, during the battery data transmission process, there may be reasons such as data loss, resulting in erroneous data during the transmission process. Erroneous data refers to data that has errors during the transmission process. The transmission detection module 10 is connected to the acquisition server 2 and detects whether there is data in the transmission data that suddenly exceeds the threshold value through time sequence. For example, the voltage data before the preset time is a stable output of 220V, but suddenly drops to 110V or increases to 360V at the preset time. However, after the preset time, the voltage data returns to 22V. This indicates that the voltage data acquired at the preset time is erroneous and is identified as erroneous data.

[0044] It should be noted that only cases where the voltage suddenly rises or falls and returns to normal data within a short period of time (within a predetermined time) are judged as erroneous data. For example, if the data rises or falls gently, for example, the voltage at the nth second is 220V, the voltage at the n+2th second is 230V, the voltage at the n+4th second is 240V..., and the voltage at the n+Nth second is 360V. In the above case, the voltage gradually rises and does not return to 220V for a long time, which may indicate a malfunction of the energy storage station. The above data is not judged as transmitted data with errors. For example, if the voltage at the nth second is 220V, the voltage at the n+2th second is 360V, the voltage at the n+4th second is 360V..., and the voltage at the n+Nth second is 360V, the voltage suddenly rises but does not return to 220V for a long time, which may also indicate a malfunction of the energy storage station. Similarly, the data is not judged as erroneous data in the transmitted data.

[0045] It should be noted that the above-mentioned error data determination process is an existing technology and can be implemented using any server with processing capabilities on the market. The above-mentioned error data determination process is to realize the transmission function of the battery data transmission system, which can be set as a hardware module and only needs to embed a CPU chip.

[0046] Optionally, if erroneous data exists, it may lead to errors in subsequent battery data detection by cloud server 8. In this case, the erroneous data needs to be corrected to effectively prevent subsequent cloud server 8 from misjudging the energy storage power station as a malfunction. Specifically, if erroneous data exists, an alarm is issued by alarm module 11, reminding staff to promptly review the erroneous data and make corrections, effectively ensuring the accuracy and stability of battery data transmission, thereby effectively achieving real-time monitoring of the safety of the energy storage power station.

[0047] like Figure 1 As shown, the battery data transmission system further includes: a data modification module 12 connected to the collection server 2 , for correcting erroneous data in the collection server 2 .

[0048] With the above structure, based on the above-mentioned situation where there is erroneous data, it may be possible that the staff cannot make corrections in time. A data modification module 12 can be set up. The data correction module calculates the average value based on the battery data at the previous moment and the battery data at the next moment, and automatically replaces the above-mentioned erroneous data with the average value to realize automatic correction of the erroneous data.

[0049] It should be noted that the above-mentioned error data correction process is an existing technology and can be implemented using any server with processing capabilities on the market. The above-mentioned error data correction process is to realize the transmission function of the battery data transmission system, which can be set as a hardware module and only needs to be embedded in a CPU chip.

[0050] like Figure 1 As shown, the battery data transmission system also includes: a power supply module 13, which is connected to the acquisition server 2 and is used to supply power to at least the acquisition server 2, the Netty communication module 3, the 104 protocol module 4 and the data processing module 7.

[0051] With the above structure, the acquisition server 2 may be placed on the main console side together with the cloud server 8, or it may be set between the battery management module 1 and the cloud server 8 (main console). When the acquisition server 2 is not set on the main console side, the acquisition server 2 and the hardware modules connected to the acquisition server 2 need to be powered separately. That is, the power module 13 is used to power the acquisition server 2. The acquisition server 2 is connected to the Netty communication module 3, the 104 protocol module 4, and the data processing module 7 via an interface line, which also has the function of powering on. Therefore, while the power module 13 powers the acquisition server 2, it also has the effect of powering the Netty communication module 3, the 104 protocol module 4, and the data processing module 7, ensuring the normal power supply and use of the above hardware modules.

[0052] like Figure 1As shown, the battery data transmission system also includes: a restart module 14, which is connected to the transmission detection module 10; the transmission detection module 10 is also used to transmit error data to the restart module 14; the restart module 14 is also connected to the power module 13, and is used to restart the power module 13 when error data is received.

[0053] With the above structure, if there is erroneous data, and the erroneous data exceeds a preset number, it may be due to an error in a set parameter in the transmission system, resulting in excessive erroneous data in the battery data transmission process. In this case, the restart module 14 is used to restart the entire battery data transmission system and reset the parameters in the transmission system to correct the erroneous data during the battery data transmission process and reduce the number of erroneous data during the battery data transmission process. Specifically, the restart module 14 is used to disconnect the power module 13 and then reconnect the power supply to restart the battery data transmission system. This effectively improves the accuracy of the battery data transmission.

[0054] The device provided by the embodiment has the following beneficial effects:

[0055] (1) By setting the Netty communication module 3, a transmission control protocol channel (TCP channel) can be established between the battery management module 1 and the acquisition server 2 to achieve efficient and stable transmission of battery data;

[0056] (2) By setting up a network gate 6, the battery data is transmitted unidirectionally from the battery management module 1 to the gateway switch 5, effectively realizing the transmission of the battery data to the collection server 2;

[0057] (3) An alarm is issued through the alarm module 11 to remind the staff to check the above-mentioned erroneous data in time and correct it in time, effectively achieving the accuracy and stability of battery data transmission, thereby effectively realizing real-time monitoring of the safety of the energy storage power station.

[0058] Based on the above embodiments and optional embodiments, the present invention proposes an optional implementation method: Figure 2 This is a schematic structural diagram of an optional battery data transmission system according to an embodiment of the present utility model. Figure 2 As shown, the system includes:

[0059] The three-level battery management system (Battery Management System, three-level BMS), equivalent to the battery management module 1 of the above embodiment, is responsible for monitoring the battery management system status of the energy storage power station and collecting battery data such as battery voltage, current, temperature, etc.

[0060] Collection server 2 is used to receive battery data from the third-level BMS.

[0061] The gateway switch 5 is used to establish and maintain the communication connection between the acquisition server 2 and the third-level BMS, and configure the network switch to achieve efficient and stable transmission of battery data.

[0062] The network communication framework module (Netty communication module) is used to establish and maintain the Transmission Control Protocol channel (TCP channel) between the acquisition server 2 and the gateway switch 5. At the same time, it uses the gateway switch 5 to access the third-level BMS to ensure efficient and stable transmission of battery data.

[0063] The 104 protocol module 4 is used to convert the battery data sent by the three-level BMS into data (i.e., transmission data) that conforms to the 104 protocol format so that the acquisition server 2 can correctly receive and process the data.

[0064] The data collection server 2 is also used to deploy a data collection program, establish a communication channel with the gateway switch 5 through the Netty communication module 3, and receive data from the third-level BMS through the 104 protocol module 4. The data collection server 2 is responsible for performing preliminary processing on the received data and then transmitting the processed data to the cloud server 8 through the Netty communication module 3.

[0065] The data processing module 7 is deployed on the acquisition server 2 and is responsible for preprocessing and filtering the received transmission data to ensure the accuracy and consistency of the transmission data, and performing format conversion to obtain digital data so that the digital data is suitable for uploading to the cloud server 8 and can be recognized by the cloud server 8.

[0066] The cloud server 8 receives the processed digital data from the acquisition server 2, stores and further analyzes and processes it, supports remote access and monitoring, and realizes real-time monitoring and management of the operating status of the energy storage power station.

[0067] The energy storage power station in this utility model utilizes Netty communication technology to achieve efficient data transmission between the data collection server 2 and the three-level BMS. Netty communication technology offers powerful single-machine concurrent processing capabilities of millions, ensuring efficient and stable battery data transmission. Through the Netty communication module 3, the 104 protocol module 4, and the data processing module 7, processed battery data is securely and stably transmitted to the cloud server 8. This entire process not only ensures the real-time and reliable transmission of battery data, but also significantly improves the monitoring and management efficiency of the energy storage power station.

[0068] In addition, it should be noted that the optional or preferred implementation of this embodiment can be found in the relevant description in the embodiment, which will not be repeated here.

[0070] In the above embodiments of the present invention, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0071] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
