[0003] However, there are some defects in the existing solutions: different manufacturers have different modeling rules for measurement point data, and the full amount of data they collect requires different adaptation processing on the cloud platform, which makes the configuration cost too high; different power stations have different scales and different numbers of measurement points. The number of measurement points in a large energy storage power station can be about ten times that of a small energy storage power station.

[0025] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0026] The following describes the data transmission method and device of the energy storage power station according to the embodiment of the present application with reference to the accompanying drawings.

[0027] Figure 1 is a flow chart of a data transmission method of an energy storage power station provided in accordance with an embodiment of the present application, such as Figure 1 As shown, the data transmission method of the energy storage power station in the embodiment of the present application includes but is not limited to the following steps:

[0028] S101, acquiring equipment data information of an energy storage power station, where the equipment data information includes structure information and data point information of a plurality of equipment.

[0029] It should be noted that the execution subject of the data transmission method of the energy storage power station provided in the embodiment of the present application is an electronic device and a server, and the electronic device can be a terminal device. Optionally, the terminal device can be a mobile electronic device or a non-mobile electronic device. Optionally, the server includes but is not limited to a network server, an application server, or a server of a distributed system, or a server combined with a blockchain, etc. The embodiment of the present application is not specifically limited.

[0030] In some implementations, the structural information and data point information of multiple devices in the energy storage power station can be determined based on the construction plan of the energy storage power station. The equipment of the energy storage power station includes but is not limited to: battery packs, energy storage controllers, chargers, energy storage converters, etc.; the data point information includes but is not limited to: data point information of the battery management system, data point information of the energy storage converter, data point information of the power distribution system and auxiliary system, etc.

[0031] S102, modeling the energy storage power station based on the equipment data information to obtain a target file of the energy storage power station.

[0032] In some implementations, the energy storage power station can be modeled based on the measurement points of each device in the device data information to obtain a model file of the energy storage power station as a target file. Optionally, the measurement points can be encoded based on data encoding rules, and the encoded data can be represented in a horizontal structure to establish a data model of the energy storage power station and obtain a model file of the energy storage power station.

[0033] Optionally, data encoding rules can be determined based on data attribute information such as system declaration, data block start mark, data block header definition, data block, and data block end mark of the energy storage power station. Among them, the system declaration is information such as the location, time, and system where the data is generated; the data block start mark and data block end mark contain the type of the measurement point of the data; the data block header definition consists of a row of data groups, and each data in the group is the data type collected by the device; the data block consists of multiple data rows, and the expression of each data row corresponds one-to-one to the data block header definition.

[0034] In some implementations, data collection is performed on the energy storage power station based on the measurement points in the equipment data information to obtain the measurement data of the energy storage power station, and the measurement data file of the energy storage power station is determined based on the measurement data, and the measurement data file is used as the target file. Optionally, an alarm file of the energy storage power station can also be obtained, and the alarm file is used as the target file. In other words, the target file includes the model file, measurement data file, and alarm file of the energy storage power station.

[0035] S103, based on the forward isolation technology, the data acquisition server transmits the target file to the forwarding server, and the forwarding server transmits the target file to the cloud server.

[0036] In some implementations, the data collection server and the forwarding server can be connected using an internal and external dual network. The forwarding server is connected to the external network and then communicates with the cloud server. The data collection server uses forward isolation technology, adopts comprehensive filtering, access control, and application proxy technology, and implements isolation of the link layer, network layer, and application layer to communicate with the forwarding server, so that the target file can only be sent from the data collection server to the forwarding server.

[0037] In some implementations, in order to ensure that data can only be transmitted from the data acquisition server to the forwarding server, an isolation device can be installed between the data acquisition server and the forwarding server based on forward isolation technology to prevent reverse communication and ensure network security of the data acquisition server.

[0038] It is understandable that the isolation device has functions such as unidirectional data transmission, status detection function, address binding function, bidirectional address conversion function, dual-machine hot standby function, log audit, etc., prohibits the two application gateways of the external network from directly establishing a Transmission Control Protocol (TCP) connection, and decomposes the TCP connection between the two internal and external application gateways into two TCP virtual connections from the two internal and external application gateways to the two internal and external network cards of the isolation device respectively. The two internal and external network cards of the isolation device are non-network connections inside the device, and only allow one-way data transmission.

[0039] Optionally, a port dedicated to the isolation device can be configured on the data acquisition server, and the generated target file can be sent through the port. The other end interface of the isolation device is connected to the forwarding server, and a corresponding receiving program is configured on the forwarding server to receive the target file.

[0040] In some implementations, after receiving the target file, the forwarding server can perform an integrity check on the target file to determine whether the target file is complete and detect whether there is erroneous data in the target file. That is to say, the forwarding server verifies the integrity of the target file, obtains the error information in the target file, and removes the error information from the target file to obtain a complete and correct target file, and then transmits the target file to the cloud server.

[0041] In some implementations, by detecting the target file before transmission, the unified data format, rich data types, and comprehensive data content are guaranteed in the process of data transmission from the energy storage power station to the cloud, and the redundant elimination of erroneous data is performed to a certain extent, thereby achieving the unification of cloud data analysis, increasing the efficiency of data analysis, and reducing the difficulty of difference processing.

[0042] In some implementations, the target file can be encrypted and compressed, and the encrypted and compressed target file can be transmitted to the cloud server. Optionally, the forwarding server is connected to the external gateway through a vertical encryption device and a firewall, and then a point-to-point encrypted tunnel is established between the forwarding server and the cloud server through a virtual private network (VPN), and the encrypted and compressed target file is sent to the cloud server, thereby realizing a triple encrypted high-security transmission mechanism.

[0043] In the data transmission method of the energy storage power station provided in the embodiment of the present application, the target file of the energy storage power station is obtained by acquiring the equipment data information of the energy storage power station and modeling the energy storage power station based on the equipment data information. Then, the data acquisition server transmits the target file to the forwarding server, and the forwarding server transmits the target file to the cloud server. By adopting the form of isolated transmission, the data is sent to the forwarding server, and then the data is encrypted and compressed by data tunneling, data encryption, and lossless compression, which improves the data transmission efficiency, avoids the risk of data leakage, and ensures the security of data transmission.

[0044] Figure 2 is a flow chart of a data transmission method of an energy storage power station provided in accordance with an embodiment of the present application, such as Figure 2 As shown, the data transmission method of the energy storage power station in the embodiment of the present application includes but is not limited to the following steps:

[0045] S201, acquiring equipment data information of an energy storage power station, where the equipment data information includes structure information and data point information of a plurality of equipment.

[0046] In the embodiment of the present application, the implementation method of step S201 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0047] S202: Determine the respective measuring points of a plurality of devices of the energy storage power station based on the device data information.

[0048] S203, coding and sorting the measuring points to obtain a coding file of the energy storage power station.

[0049] It can be understood that the measuring point refers to the measuring location set up during the operation of the energy storage power station equipment to monitor the specific parameters or status of the equipment. These measuring points can provide real-time or periodic data on the operation of the equipment to assess the health status, performance and potential problems of the equipment.

[0050] Optionally, the operating parameters of each device may be acquired based on the device data information, and respective measuring points may be set for each device based on the operating parameters.

[0051] In some implementations, after the respective measuring points of the devices are determined, coding is sorted based on the measuring points to obtain a coding file of the energy storage power station.

[0052] S204, obtaining data encoding rules, and based on the data encoding rules, modeling the encoding file to obtain a model file of the energy storage power station, and using the model file as the target file.

[0053] In some implementations, data encoding rules may be determined based on data attribute information so that the data encoding rules conform to the data attributes. That is, data attribute information of device data information may be obtained, and data encoding rules may be determined based on the data attribute information.

[0054] Optionally, the data attribute information includes: system declaration of the energy storage power station, data block start mark, data block header definition, data block, data block end mark, etc. Among them, the system declaration is information such as the location, time and system where the data is generated; the data block start mark and data block end mark contain the type of the measurement point of the data; the data block header definition consists of a row of data groups, and each data in the group is the data type collected by the device; the data block consists of multiple data rows, and the expression of each data row corresponds to the data block header definition one by one.

[0055] In some implementations, the encoded file can be encoded according to data encoding rules, and the encoded data can be modeled using a horizontal representation structure to obtain a data model of the energy storage power station, and a model file can be generated based on the data model as a target file.

[0056] In some implementations, the measurement data file and alarm data file of the energy storage power station can also be used as the target file. The measurement data and alarm data of each measuring point of the energy storage power station can be obtained based on the device data information, and then the measurement data file and the alarm data file can be determined based on the measurement data and the alarm data. By collecting data for the energy storage power station based on the respective measuring points of each device in the device data information, the measurement data and alarm data of each measuring point can be obtained.

[0057] Optionally, the measurement data is type-identified to obtain telemetry data and telesignaling data in the measurement data, and the telemetry data and telesignaling data are converted into telemetry files and telesignaling files based on the set file generation frequency and data encoding rules. In other words, the measurement data file includes the telemetry file and the telesignaling file.

[0058] Optionally, based on data encoding rules, the alarm data can be extracted to obtain an alarm file, and then the telemetry file, telesignaling file, and alarm file are used as target files, and the target files are transmitted to the forwarding server.

[0059] In some implementations, when generating the measurement data file, the measurement data file may be generated based on the data encoding rule and at a set frequency, wherein the set frequency should be greater than twice the shortest update frequency of the collected data.

[0060] In some implementations, after obtaining the model file, the telemetry file, the telesignal file, and the alarm file, the above-mentioned multiple files can be converted into a unified format. Optionally, the files in a unified format can be divided into a model file, a telemetry file, a telesignal file, and an alarm file based on the identification information of the file.

[0061] S205, based on the forward isolation technology, the data acquisition server transmits the target file to the forwarding server, and the forwarding server transmits the target file to the cloud server.

[0062] In the embodiment of the present application, the implementation method of step S205 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0063] In the data transmission method of the energy storage power station provided in the embodiment of the present application, the equipment data information of the energy storage power station is obtained, and the energy storage power station is modeled based on the equipment data information to obtain the model file of the energy storage power station, and the measurement data file and the alarm file are obtained from the equipment data information, and the model file, the measurement data file and the alarm file are used as the target file. Then, the data acquisition server transmits the target file to the forwarding server, and the forwarding server transmits the target file to the cloud server. By adopting the form of isolated transmission, the data is sent to the forwarding server, and then the data is encrypted and compressed by data tunneling, data encryption, and lossless compression, which improves the data transmission efficiency, avoids the risk of data leakage, and ensures the security of data transmission.

[0064] Figure 3 is a flow chart of a data transmission method of an energy storage power station provided in accordance with an embodiment of the present application, such as Figure 3 As shown, the data transmission method of the energy storage power station in the embodiment of the present application includes but is not limited to the following steps:

[0065] S301, acquiring equipment data information of an energy storage power station, where the equipment data information includes structure information and data point information of a plurality of equipment.

[0066] In the embodiment of the present application, the implementation method of step S301 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0067] S302, modeling the energy storage power station based on the equipment data information to obtain a target file of the energy storage power station.

[0068] In the embodiment of the present application, the implementation method of step S302 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0069] S303, based on the forward isolation technology, a Transmission Control Protocol TCP connection is established between the data acquisition server and the forwarding server.

[0070] In some implementations, the data collection server and the forwarding server are connected in an internal and external dual network. The forwarding server is connected to the external network and then communicates with the cloud server. The data collection server uses forward isolation technology, adopts comprehensive filtering, access control, and application proxy technology, and implements isolation of the link layer, network layer, and application layer to communicate with the forwarding server, so that the target file can only be sent from the data collection server to the forwarding server.

[0071] In some implementations, an isolation device can be installed between the data acquisition server and the forwarding server based on the forward isolation technology to prevent reverse communication and ensure the network security of the data acquisition server. The isolation device establishes a TCP connection between the data acquisition server and the forwarding server by decomposing the Transmission Control Protocol (TCP) connection between the two internal and external application gateways into two TCP virtual connections from the two internal and external application gateways to the two internal and external network cards of the isolation device, respectively.

[0072] S304, the data acquisition server transmits the target file to the forwarding server based on the TCP connection.

[0073] In some implementations, a port dedicated to the isolation device can be configured on the data collection server, and the generated target file can be sent through the port. The other end interface of the isolation device is connected to the forwarding server, and the corresponding receiving program is configured on the forwarding server to receive the target file.

[0074] That is, the data acquisition server can establish a TCP connection according to the isolation device, and send the target file to the forwarding server based on the TCP connection of the isolation device.

[0075] S305, the forwarding server transmits the target file to the cloud server.

[0076] In the embodiment of the present application, the implementation method of step S305 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0077] In the data transmission method of the energy storage power station provided in the embodiment of the present application, the target file of the energy storage power station is obtained by acquiring the equipment data information of the energy storage power station and modeling the energy storage power station based on the equipment data information. Then, the data acquisition server transmits the target file to the forwarding server based on the forward isolation technology, and the forwarding server transmits the target file to the cloud server. By adopting the form of isolated transmission, the data is sent to the forwarding server, and then the data is encrypted and compressed by data tunneling, data encryption, and lossless compression, which improves the efficiency of data transmission, avoids the risk of data leakage, and ensures the security of data transmission.

[0078] Figure 4 is a flow chart of a data transmission method of an energy storage power station provided in accordance with an embodiment of the present application, such as Figure 4 As shown, the data transmission method of the energy storage power station in the embodiment of the present application includes but is not limited to the following steps:

[0079] S401, acquiring equipment data information of an energy storage power station, where the equipment data information includes structure information and data point information of a plurality of equipment.

[0080] In the embodiment of the present application, the implementation method of step S401 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0081] S402, modeling the energy storage power station based on the equipment data information to obtain a target file of the energy storage power station.

[0082] In the embodiment of the present application, the implementation method of step S402 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0083] S403, based on the forward isolation technology, the data acquisition server transmits the target file to the forwarding server.

[0084] In the embodiment of the present application, the implementation method of step S403 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0085] S404, determining the file size of the target file.

[0086] In some implementations, in order to ensure data transmission efficiency, the target file may be converted according to the file size of the target file, and the converted target file may be sent to the cloud server. That is, by determining the file size of the target file and comparing the file size with the file size threshold, the target format for format conversion of the target file is determined.

[0087] S405, in response to the file size being less than or equal to the file size threshold, converting the target file into a target JS key-value pair data JSON file, and transmitting the target JSON file to the cloud server based on the message queue telemetry transmission MQTT protocol.

[0088] In some implementations, if the file size is less than or equal to a file size threshold and the target file is determined to be a small or medium batch of data, the target file can be converted into a target JS key-value pair data (JavaScript Object Notation, JSON) file.

[0089] Optionally, the target file may be converted into a corresponding target JSON file in a manner of attribute parsing, feature extraction, hierarchization, and serialization.

[0090] It can be understood that the JSON structured file follows the previous interaction specification definition with the system declaration, data block, and data block end marker as the main structure, and the data block content tag is defined by the data block header declaration. This method has the characteristics of simple grammatical format and detailed hierarchical structure, which is convenient for the forwarding server to fill in and generate JSON data from data files, and easy for the cloud server to operate and parse the data.

[0091] Furthermore, the target JSON file is transmitted to the cloud server using the Message Queuing Telemetry Transport (MQTT) protocol.

[0092] It is understandable that the MQTT protocol is lightweight, sophisticated, open and easy to implement. It has the characteristics of small-scale transportation and minimized protocol exchange in the process of small and medium-volume data communication. It adopts a publishing and consumption communication mechanism, with the forwarding server as the publisher and the cloud server as the consumer. Once the data file is published, the platform can subscribe to the corresponding information and read the corresponding data. This protocol can significantly reduce network traffic and facilitate rapid construction and deployment.

[0093] S406, in response to the file size being greater than the file size threshold, converting the target file into a target data stream file, and transmitting the target data stream file to the cloud server based on bus communication.

[0094] In some implementations, if the file size is greater than a file size threshold, the target file is determined to be a large batch of data, and the target file is converted into a target data stream file. Optionally, the target file can be converted into a target data stream file by format sequence, data extraction, and stream segment parsing.

[0095] Furthermore, the target data stream file can be transmitted in the communication network based on bus communication. Optionally, a half-duplex bus communication structure can be adopted, and the receiving end does not provide feedback and confirmation when receiving the target data stream file, but only replaces the corresponding target data stream file with the corresponding data file by monitoring the data bus to read the corresponding data content.

[0096] In some implementations, the above-mentioned communication bus is configured with corresponding functions such as multi-device management, interrupt mechanism, error handling, etc., to provide each server device with bus application, occupancy, addressing and data transmission, thereby avoiding transmission conflicts, system errors, data confusion and other problems during data transmission, and further improving the transmission efficiency and quality of large amounts of data; at the same time, the cost of processing delay in the end-side data stream format greatly reduces the transmission delay, further improves the transmission efficiency, and provides a guarantee for the transmission of large amounts of data.

[0097] In some implementations, the forwarding server may encrypt and compress the target JSON file and the target data stream file, and transmit the encrypted and compressed files to the cloud server. Optionally, the cloud server may be authenticated based on the target address, and the encryption public key of the cloud server may be obtained to encrypt the file.

[0098] In some implementations, the target cloud server is determined from the candidate cloud servers by obtaining the target address to be transmitted and verifying multiple candidate cloud servers based on the target address, and a link is established with the target cloud server. Further, the forwarding server obtains the verification certificate of the target cloud server based on the link, and obtains the encryption public key based on the verification certificate.

[0099] Furthermore, for any file in the target JSON file and the target data stream file, any file is encrypted using the encryption public key, and any encrypted file is compressed to obtain a compressed file, so that the forwarding server transmits the compressed file to the target cloud server based on the link.

[0100] In some implementations, the file can be compressed based on XOR algorithm dictionary order compression. Any file is encrypted by using an encryption public key, and any encrypted file is converted into a binary data stream, and the first sequence data and the last sequence data of the binary data stream are obtained, and the first sequence data is used as the first feature value.

[0101] Furthermore, an XOR operation is performed on the first sequence data and the second sequence data to obtain a data segment matrix, and an eigenvalue is extracted from the data segment matrix to obtain a second eigenvalue. Then, based on the first eigenvalue and the second eigenvalue, any encrypted file can be compressed to obtain a compressed file.

[0102] In some implementations, when performing an XOR operation, if the lengths of the first sequence data and the second sequence data are different, the tail of the insufficient data can be padded with zeros to ensure that the lengths of the first sequence data and the second sequence data files are consistent, thereby forming a data segment matrix with the first sequence length as the horizontal length and the ratio of the data horizontal length as the vertical length.

[0103] In other words, through XOR operation and zero padding, it is ensured that the proportion of zero elements in the data sequence exceeds 50%, which ensures that the effective bit splicing operation is reduced during compression calculation, and improves the compression efficiency. At the same time, using determinant calculation and dictionary order compression method, the data is losslessly compressed, thereby further improving the compression efficiency.

[0104] In some implementations, after receiving the compressed file, the cloud server decompresses the compressed file to obtain a binary data stream, and performs format conversion on the binary data stream to obtain an encrypted target file. Optionally, the cloud server can decompress the compressed file according to the first eigenvalue and the second eigenvalue to obtain a binary data stream.

[0105] Furthermore, a decryption private key may be obtained based on the verification certificate, and the encrypted target file may be decrypted based on the decryption private key to obtain the target file.

[0106] In some implementations, an energy storage power station can be deployed at the edge, and one-click deployment can be performed on the corresponding forwarding server and data acquisition server to build a forwarding environment and establish communication with the cloud server. After the communication is established, the data acquisition server generates the corresponding target file according to the data encoding rules based on the equipment data information of the energy storage power station and sends it to the cloud server by the forwarding server.

[0107] In some implementations, after receiving the target file, the cloud server can verify the integrity of the target file based on the data attribute information, and store the target file in the database after the verification is passed. Optionally, if the target file fails to pass the verification, a prompt message is sent to the energy storage power station, and the prompt message is used to instruct the energy storage power station to re-transmit the data.

[0108] Optionally, the overall format of the target file can be confirmed to be legal and the corresponding configuration can be read by comparing whether the file system declaration in the data attribute information is complete and whether the data block start marks can correspond one to one.

[0109] In some implementations, after confirming that the file is complete, the cloud server can also read the model and configuration data of all measuring points in the energy storage power station from the target file, that is, the equipment data information, and establish a candidate data model of the energy storage power station with the measuring point as the unit based on the equipment data information, and generate the corresponding measuring point data matching rules through the candidate model, and match the candidate data model and the data model transmitted in the target file based on the matching rules to determine whether the transmitted data is complete. After the cloud platform receives the model file, according to the processing results, in some implementations, the cloud server can send a corresponding confirmation reply to the energy storage power station based on the matching results, where the confirmation reply includes a prompt for illegal retransmission of the model, a prompt for missing model data, and a confirmation of data model establishment. The energy storage power station performs the next step according to the feedback from the cloud server. In the case of illegal model, the forwarding server regenerates and completes the model data and sends it twice; when the data is missing, the model data is retransmitted; under model confirmation, the forwarding server confirms that the data model is available and starts forwarding the data file sent by the centralized procurement server.

[0110] In the data transmission method of the energy storage power station provided in the embodiment of the present application, the target file of the energy storage power station is obtained by acquiring the equipment data information of the energy storage power station and modeling the energy storage power station based on the equipment data information. Then, the data acquisition server transmits the target file to the forwarding server, and the forwarding server converts the target file into a different file format based on the file volume of the target file, and transmits the target file to the cloud server based on the transmission method corresponding to the different file formats. By adopting the form of isolated transmission, the data is sent to the forwarding server, and then the data is encrypted and compressed by data tunneling, data encryption, and lossless compression, the data transmission efficiency is improved, the risk of data leakage is avoided, and the security of data transmission is ensured.

[0111] As an example, a transmission system can be determined based on the data transmission method of the energy storage power station proposed in the embodiment of the present application, and data transmission can be performed based on the transmission system. Figure 5 The structural diagram of the data transmission system shown. Figure 5 In the example, the data acquisition server is located in the power grid area I, and the forwarding server is located in the power grid area III / IV.

[0112] The data acquisition server obtains the equipment data information of the energy storage power station based on the information acquisition equipment of the energy storage power station, and determines the model file, measurement data file and alarm file of the energy storage power station as the target file based on the equipment data information, and sends the target file to the forwarding server based on the forward isolation device between the data acquisition server and the forwarding server. After receiving the target file, the forwarding server converts the target file into a target data stream file or a target JSON file based on the file volume of the target file. Furthermore, the target data stream file or the target JSON file is transmitted to the cloud server based on the corresponding transmission method. It is linked to the firewall through vertical isolation technology, the firewall is linked to the gateway, the gateway is connected to the communication network, and thus linked to the cloud server.

[0113] Figure 6 The figure shows a flow chart of data transmission. In the first area of ​​the power grid, the data acquisition server obtains the equipment data information of the energy storage power station, and generates a target file based on the equipment data information, so as to transmit the target file to the forwarding server in the third area of ​​the power grid based on the forward isolation technology.

[0114] The forwarding server converts the target file into a target data stream file or a target JSON file according to the file size of the target file, and then encrypts any file in the target data stream file and the target JSON file using the public key, and compresses the encrypted file using the XOR algorithm dictionary order to obtain a compressed file. Based on the data transmission method corresponding to the compressed file, the compressed file is transmitted using the bus or MQTT protocol, and sent to the cloud server through the VPN encrypted tunnel.

[0115] After receiving the compressed file, the cloud server decompresses it based on the XOR algorithm lexicographic order, decrypts the decompressed file using the private key to obtain the target file, and stores and displays the target file.
