[0052] <System Embodiment>

[0053] Please see Figure 1 , which is a schematic diagram of the structure of the energy storage data management system provided by the embodiment of the present disclosure. Figure 1As shown, the energy storage data management system 100 provided by the embodiment of the present disclosure includes at least one energy storage system 1000, a cloud server 2000, a user terminal 3000 and a network 4000, wherein the energy storage system 1000 and the cloud server 2000 can communicate through the network 4000 using a preset remote communication technology, and the user terminal 3000 and the cloud server 2000 can communicate through the network 4000.

[0054] Please see Figure 2 , which is a schematic diagram of the structure of the cloud server provided by the embodiment of the present disclosure. Figure 2 As shown, in one embodiment, the cloud server 2000 may include a data receiving device 2100 and a data storage device 2200, wherein the data receiving device receives the encrypted data portion sent by the energy storage system 1000 according to a preset long-distance communication technology; and decrypts and parses the data portion to obtain standard energy storage data, and stores the standard energy storage data. In addition, the cloud server 2000 may include a request response device 2300, wherein the request response device 2300 is used to receive a data viewing request sent by the user terminal 3000, and generate a response message corresponding to the data viewing request according to the standard energy storage data, and provide the response message to the user terminal.

[0055] It should be noted that, in a specific implementation, the cloud server 2000 may be, for example, a blade server, a rack server, etc. In the system 100, the number of the cloud servers 2000 may be one or more, for example, a server cluster, and no special limitation is made here.

[0056] Please see Figure 3 , which is a schematic diagram of the structure of the energy storage system provided by the embodiment of the present disclosure. Figure 3 As shown, the energy storage system 1000 at least includes: a data acquisition device 1100 , a data processing device 1200 , a first data transmission device 1300 and a second data transmission device 1400 .

[0057] The data acquisition device 1100 is used to acquire raw energy storage data and send the raw energy storage data to the data processing device.

[0058] Specifically, Figure 3 As shown, the energy storage system may also include Figure 3 The BMS battery management subsystem 1500 (Battery Management System) shown in FIG. 1 includes Figure 3The process control module 1501 (PCS, Process Control Systems), the battery pack 1502 and the battery boost and capacity expansion control module 1503 (DC-DC, DC-DC Converter) are shown.

[0059] The BMS battery management subsystem 1500 is used to collect, analyze and process the operating data generated by each module it contains to generate original energy storage data; wherein, the process control module 1501 is used to control the grid-connected charging and discharging and off-grid PV charging functions and collect corresponding data; the battery boost and capacity expansion control module 1503 is used to control the boost and capacity expansion functions of the battery pack 1502 and collect corresponding data.

[0060] The original energy storage data may include multiple data items, for example, three voltage values, current values, etc.; in addition, the multiple data items may belong to different data item categories, and the data item categories may include, for example: operation data, parameter data, command data. Those skilled in the art can obviously understand the meaning of the different categories of data based on common knowledge, and will not be elaborated here.

[0061] like Figure 3 As shown, the BMS battery management subsystem 1500 can communicate with the process control module 1501 and the battery boost and expansion control module 1503 based on the controller area network bus (CAN) 2, and can communicate with the battery pack 1502 based on a serial component, for example, a serial peripheral interface (SPI).

[0062] In one embodiment, the data acquisition device 1100 can communicate with the BMS battery management subsystem 1500 via the controller area network bus 1 and other user-defined protocols to obtain the original energy storage data.

[0063] The data processing device 1200 is used to receive the original energy storage data and convert the original energy storage data into standard energy storage data. That is, the data processing device is used to perform format conversion, simple calculation, judgment and format conversion on the original energy storage data to obtain standard energy storage data.

[0064] The first data transmission device 1300 is used to receive the standard energy storage data, generate a serial port data frame according to the standard energy storage data; and send the serial port data frame to the second data transmission device using a preset serial port communication technology; wherein the serial port data frame includes a frame header and a data portion, the data portion stores the standard energy storage data in a key-value format, and the frame header is used to store control data of the serial port data frame.

[0065] The second data transmission device 1400 is used to receive the serial port data frame using the preset serial port communication technology; when it is determined according to the control data in the frame header that the data portion meets the preset conditions, the data portion is cut from the serial port data frame according to the control data, and the data portion is encrypted; and the encrypted data portion is sent to the cloud server using the preset long-distance communication technology.

[0066] Specifically, the energy storage system 1100 provided in the embodiment of the present disclosure performs data communication between the serial port component (not shown in the figure), the first data transmission device 1300 and the second data transmission device 1400 through a preset serial communication technology based on the serial port component, wherein the serial port (Serial Interface) component, whose full name is serial interface component, is an extended interface using a serial communication method.

[0067] In the prior art, when encapsulating a serial port data frame, it is generally encapsulated and framed according to the serial port communication protocol shown in Table 1, wherein the data type identifier in Table 1 is used to identify the content of the data item, and the subsequent data items 1 to N are the data lengths and data meanings predefined in the serial port communication protocol, for example, data item 1 represents voltage value 1, data item 2 represents current value 2, etc. In the prior art, for different collected data items, the sender usually frames each data item and sends it to the receiver through a serial port component; after the receiver receives the data frame based on the serial port component, it needs to parse it item by item according to the serial port transmission protocol to restore the data item and store it.

[0068] The problem with this method is that, on the one hand, when encapsulating and framing based on a serial communication protocol similar to that described in Table 1, even if the data of a certain data item is not collected, it is necessary to reserve a position for the data item in the data frame, otherwise, the receiver will not be able to parse the data frame normally, which results in a problem of wasted bytes; at the same time, during the transmission process, if an error occurs in a certain data item, it may cause the receiver to parse all subsequent data items incorrectly, thereby reducing the fault tolerance of the data frame.

[0069]

[0070] Table 1

[0071] To solve this problem, in an embodiment of the present disclosure, when the first data transmission device 1300 generates a serial port data frame according to the standard energy storage data, it is used to: obtain at least one preset key value corresponding to each data item in the energy storage data, and generate at least one key-value data pair according to the corresponding preset key value and data item; generate the data part according to the at least one key-value data pair; obtain the verification data and data length of the data part; construct the control data according to the verification data and the data length, the message type corresponding to the standard energy storage data, and the data type corresponding to the standard energy storage data to generate the frame header; encapsulate the frame header and the data part to generate the serial port data frame.

[0072] In one embodiment, the at least one key-value data in the data portion generated by the first data transmission device 1300 is stored in a serial manner.

[0073] Please refer to the following Table 2, which is a schematic diagram of the communication protocol of the serial port data frame provided by the embodiment of the present disclosure:

[0074]

[0075] Table 2

[0076] In Table 2, the feature code identifies the identifier of the serial port data frame provided in this embodiment, and the data length identifies the remaining data length except the 12 bytes of the header, that is, the length of the data part; the message type is used to identify the data type corresponding to the data frame, and its value can be specifically operation data (0x01), parameter data (0x02), and command data (0x03); the data type can be, for example, battery pack data (represented by number 31), installation parameter information (represented by number 632), etc. The flag bit is used to identify the success or failure of data transmission, so that in the case of transmission failure, data retransmission processing can be performed, or data transmission processing can be terminated; the check bit stores the check data, which is used by the data receiver to determine whether the received data is consistent with the sent data; the device ID is mainly used to distinguish different energy storage devices; the upload type and time are mainly used to facilitate the cloud server to screen, parse and classify data.

[0077] It should be noted that, in the embodiment of the present disclosure, the data portion in the serial port data frame can store the standard energy storage data in the JSON protocol format, and, in order to save bytes, the preset JSON protocol format is a protocol format that does not contain line breaks.

[0078] That is to say, when the serial communication protocol provided by this embodiment is used to encapsulate the serial data frame, it is not necessary to set a line break between the fields, and they can be directly arranged in sequence.

[0079] Specifically, in an embodiment of the present disclosure, in order to ensure secure transmission of data, the second data transmission device 1400 includes an encryption chip. After the second data transmission device 1400 receives the serial port data frame sent by the first data transmission device 1300 from the serial port component, in order to ensure correct transmission of the data, the second data transmission device 1400 can first obtain verification data from the frame header length according to the frame header length, and judge whether the data in the data part is correctly received based on the verification data. If it is correctly received, there is no need to parse and then encrypt the data in the data part one by one, but the data part can be directly cut out from the serial port data frame, and then the data part can be directly encrypted and the encrypted data part can be sent to the cloud server 2000 through a preset long-distance communication technology, such as socket technology.

[0080] That is, in this embodiment, the second data transmission device 1400 can determine whether the data part meets the preset condition through the following processing: after receiving the serial port communication frame, parse and obtain the verification data from the frame header; based on the verification data, verify whether the received data part is correct, and determine that the data part meets the preset condition if the verification passes.

[0081] In addition, the energy storage system in the prior art may encrypt the data before sending it to the cloud server. However, since the existing energy storage system is usually based on a traditional serial communication protocol, for example, the communication protocol shown in Table 1 encapsulates the data frame. Therefore, when the encryption chip encrypts the data, it is often necessary to first parse the data frame to obtain each data item, and then encrypt the data item and encapsulate it into a key value format to send it to the cloud server. This requires the encryption chip to be able to process data with higher complexity, thereby increasing the hardware cost of the encryption chip used.

[0082] In an embodiment of the present disclosure, the first data transmission device 1300 directly uses the key value format when encapsulating the data frame, for example, encapsulating the standard energy storage data in the JSON format; this allows the second data transmission device 1400 based on the encryption chip to obtain the serial port data frame containing the standard energy storage data without having to parse the serial port data frame, but can directly cut out the data part for transmission when the data part is determined to be correct based on the verification data in the frame header, without the need to re-encapsulate the data items in the data part, thereby reducing the computational complexity of the encryption chip, so that the encryption chip only needs to have basic encryption capabilities.

[0083] In this embodiment, when the second data transmission device 1400 cuts the data portion from the serial port data frame according to the control data, it is used to: calculate the second starting address of the data portion according to the first starting address of the serial port data frame and the frame length of the frame header; in the serial port data frame, with the second starting address as the starting position, cut the data corresponding to the data length to obtain the data portion.

[0084] According to the above description, it can be seen that the method of generating serial port data frames based on the customized serial port communication protocol provided by the embodiment of the present disclosure can, on the one hand, play a role in data protection, so that in the absence of the serial port communication protocol, the specific meaning of the data cannot be truly parsed only by the data content intercepted during the transmission process; on the other hand, the serial port communication protocol can be customized according to actual needs, which facilitates the connection of system data to an existing cloud server and simplifies the data cleaning and parsing process after the cloud server receives the data.

[0085] In one embodiment, the first data transmission device 1300 may include a data caching sub-device 1301 and a data sending sub-device 1302 .

[0086] The data cache sub-device 1301 is used to generate a serial port data frame according to the standard energy storage data, and generate a task message corresponding to the serial port data frame, and write the task message into a target cache queue; and receive a reply message corresponding to the task message provided by the second data transmission device 1400; when the reply message indicates that the data portion in the serial port data frame is successfully sent to the cloud server 2000, remove the task message from the target cache queue; and / or, when the reply message indicates that the data portion is not successfully sent to the cloud server 2000 and the number of retransmissions corresponding to the task message is greater than a preset threshold, remove the task message from the target cache queue and generate corresponding fault log information;

[0087] The data sending sub-device 1302 is used to consume the task message from the target cache queue according to a preset mechanism, and send the serial port data frame in the task message to the second data transmission device 1400 using a preset serial port communication technology, and update the number of retransmissions in the task message.

[0088] Specifically, in order to further reduce the computational complexity of the second data transmission device and ensure that the standard energy storage data can be accurately sent to the cloud server, in an embodiment of the present disclosure, the first data transmission device may also maintain a target cache queue to cache the standard energy storage data to be sent to the cloud server; for each piece of data to be sent, the first data transmission device may first generate its corresponding task message and write the task message into the target cache queue to reduce the concurrency of data transmission; thereafter, the first data transmission device may consume a task message from the target cache queue again according to a preset mechanism, for example, according to a preset time interval, or when the previous task message is processed, and send the serial port data frame in the task message to the second data transmission device through the serial port component for transmission; after the second data transmission device sends the encrypted data portion to the cloud server, the cloud server may also transmit a reply message to the second data transmission device to indicate that the data portion has been successfully received; the second data transmission device provides the reply message to the first data transmission device so that the first data transmission device can remove the task message from the target cache queue when confirming that the cloud server has successfully received it, so as to reduce the loss during the data transmission process.

[0089] In addition, according to the above description, it can also be pointed out that in the first data transmission device, even if a serial port data frame fails to be sent, the corresponding fault log information will be written into the fault log data, so that the energy storage system 1000 can resend the serial port data frame again if the retry conditions are met.

[0090] Please continue to see Figure 3 ,like Figure 3 As shown, the energy storage system 1000 provided in the embodiment of the present disclosure not only sends the energy storage data to the cloud server 2000 so that the user can remotely monitor the energy storage system at any time through the user terminal 3000; but also maintains local storage and local data viewing capabilities so that the user can conveniently monitor the operating status of the energy storage system.

[0091] Specifically, in one embodiment, the energy storage system 100 further includes a local storage subsystem 1600 and a local display subsystem 1700 .

[0092] The local storage subsystem 1600 is used to obtain standard energy storage data from the data processing device 1200 and directly store the standard energy storage data.

[0093] The local display subsystem 1700 is used to read and display the standard energy storage data stored in the local storage subsystem 1600, and to display the standard energy storage data.

[0094] like Figure 3As shown, the local storage subsystem may include a shared memory and a local database, wherein the shared memory is used to store standard energy storage data of a first type, and the local database may be used to store standard energy storage data other than the first type.

[0095] According to the above description, the energy storage system 1000 provided by the embodiment of the present disclosure collects raw energy storage data by the data acquisition device 1100 and sends the raw energy storage data to the data processing device 1200; and after the data processing device 1200 converts the raw energy storage data into standard energy storage data, it is different from the way of encapsulating data frames in the way of continuously storing data values ​​in the existing serial communication protocol. In the embodiment of the present disclosure, the data part of the serial data frame generated by the first data transmission device 1300 stores the standard energy storage data in a key-value format, that is, a key-value format, so that the user can easily view the standard energy storage data; at the same time, in order to ensure the safe transmission of data and To reduce the processing complexity of the second data transmission device 1400, after receiving the serial port data frame sent by the first data transmission device, the second data transmission device 1400 will directly cut out the data portion from the serial port data frame and encrypt it and send it to the cloud server after verifying that the data portion meets the preset conditions. In this way, on the one hand, the security of the data can be maintained. On the other hand, after the data portion is transmitted to the cloud server 2000, the cloud server 2000 can directly parse the data portion according to the key value method to obtain the standard energy storage data, so that the cloud server can respond to the data viewing request of the user terminal at any time and provide the standard energy storage data to the user for viewing, so as to improve the user experience.
