[0047] The embodiment of this specification provides a flow chart of a method for realizing reliable transmission of messages, which can effectively solve the above problems. By using the method of big data and models, combined with historical data, after data cleaning, feature extraction, and model training, after obtaining the model, it can be combined with subsequent collected data to automatically and accurately predict the abnormal charging power of the battery during the charging process.

[0048] In this specification, a method and system for implementing reliable transmission of messages are provided. This specification also relates to a computing device, a computer-readable storage medium, and a computer program, which are described in detail one by one in the following embodiments.

[0049] Figure 1 A flow chart of a method for implementing reliable message transmission according to an embodiment of this specification is shown, including:

[0050] Step S1: when message transmission is required between multiple cooperative control devices and multiple PCS devices in the energy storage cooperative control system, determining a sending device end for sending messages and a receiving device end for receiving messages among the multiple cooperative control devices and multiple PCS devices in the energy storage cooperative control system;

[0051] Furthermore, any co-control device and any PCS device can be used as both a transmitting device and a receiving device.

[0052] In the embodiment of this specification, after step S1, the method further includes:

[0053] The receiving device uses its device's local unique code to calculate and save the device's local feature code for reliable message transmission, and publishes the device's local feature code to each sending device, so that each sending device saves the receiving device's local feature code into a device's local feature code table.

[0054] In the embodiment of this specification, the receiving device uses the local unique code of its device to calculate and save the local feature code of the device for reliable message transmission, including:

[0055] The receiving device generates a local key of the receiving device by using the local unique code of the receiving device and the pre-established basic key in the energy storage cooperative control system;

[0056] The receiving device uses the local key and a pre-defined feature code polynomial to calculate and save the local feature code of the device for reliable message transmission.

[0057] In the embodiment of this specification, the cooperative control device and the PCS device in the energy storage cooperative control system communicate and control each other through messages. The system diagram is shown in FIG. Figure 4 As shown. Co-control 1 needs to receive messages from PCS1, PCS2, PCS3, Co-control 2, and Co-control m, and Co-control 1 needs to publish messages to PCS1, PCS3, Co-control 2, and Co-control m. Then Co-control 1 needs to publish the local feature code to PCS1, PCS2, PCS3, Co-control 2, and Co-control m to realize the check code processing in the message parsing and packet assembly process.

[0058] Step S2: the sending device acquires the real-time data to be transmitted to the receiving device, and combines the local device feature code of the receiving device with the real-time data to obtain a verification code;

[0059] In the embodiment of this specification, the step S2 includes:

[0060] The sending device acquires the real-time data to be transmitted to the receiving device, and searches for the local device feature code of the receiving device from a pre-stored local device feature code table;

[0061] The sending device uses the local device feature code of the receiving device and the real-time data to perform combined processing to obtain a verification code.

[0062] Furthermore, if Figure 3 As shown, the embodiment of this specification generates a local key based on the local unique code and the basic key, and the local key generates a local feature code through the feature code polynomial, and the local feature code has independent uniqueness. Among them, the example of the feature code polynomial (only as an example) is X16+X13+X12+X11+X10+X8+X6+X5+X2+1, and the local feature code and the message data are operated to generate a check code, which is used as a check code for sending and receiving messages, see the check code generation process diagram. The CRC32 polynomial x32+x26+x23+x22+x16+x12+x11+x10+x8+x7+x5+x4+x2+x+1 can be used to operate and generate a check code. The local unique code can use the local MAC address, or the DNA code of the SOC chip used by the co-control system, such as the local MAC address DC-65-73-A1-25-87, or other unique features of the local machine or their combination, such as the DNA code of the SOC chip (0x200C340680010A13). The DNA code of each SOC chip is unique. The basic key is a key formulated by a certain co-control system. This key must be stored securely and secretly. It can be a 256-bit or 128-bit agreed key string agreed by the co-control, that is, the basic password. Due to the independent uniqueness of the local unique code, the local key is also unique at the same time, and it is combined with the feature code polynomial to generate the local feature code. The message data sent or received in each frame is combined with the local feature code in real time to obtain the check code to realize the encrypted transmission of the message.

[0063] Step S3: the sending device side fills the real-time data and the check code according to the message format to obtain a current transmission message with the real-time data and the check code, and sends the current transmission message with the real-time data and the check code to the receiving device side;

[0064] In the embodiment of the present specification, the sending device end fills the real-time data and the check code according to the message format to obtain the current transmission message with the real-time data and the check code, including:

[0065] The sending device side obtains a current transmission message with real-time data by filling the real-time data according to the message format;

[0066] The sending device end obtains the current transmission message with real-time data and the check code by filling the check code into the current transmission message with real-time data according to the predetermined position of the message.

[0067] Step S4: the receiving device extracts real-time data and a check code from the current transmission message by parsing the current transmission message, and combines the extracted real-time data with its pre-stored device local feature code to obtain a current check code;

[0068] Step S5: The receiving device uses the current verification code and the extracted verification code to perform security transmission verification on the current transmission message to achieve reliable transmission and response of the energy storage cooperative control system.

[0069] In an embodiment of the present specification, the receiving device end uses the current verification code and the extracted verification code to perform secure transmission verification on the current transmission message, including:

[0070] The receiving device compares the current verification code with the extracted verification code;

[0071] If the comparison results are consistent, the receiving device determines that the real-time data in the current transmission message is reliable and valid, and performs further processing on the real-time data in the current transmission message;

[0072] If the comparison result is inconsistent, the receiving device determines that the real-time data in the current transmission message is invalid, and discards the real-time data in the current transmission message.

[0073] like Figure 5 As shown, the steps of adding a check code to the sent message by the sending device include:

[0074] Step S100: The logic processing unit of the energy storage coordination controller obtains the data to be sent and the local feature code.

[0075] Step S102: Following step S100, the logic processing unit of the energy storage coordination controller fills the data to be sent according to the message format.

[0076] Step S104: Following step S102, the logic processing unit of the energy storage coordination controller combines the data to be sent with the local feature code to calculate the current check code.

[0077] Step S106: Following step S104, the logic processing unit of the energy storage coordination controller fills the current verification code into the agreed position of the sent message.

[0078] Step S108: Following step S106, the logic processing unit of the energy storage coordination controller sends the message filled with the current verification code.

[0079] like Figure 6 As shown, the steps for the receiving device to determine whether the check codes in the received message are consistent include:

[0080] Step S200: The logic processing unit of the energy storage coordination controller parses the received message and synchronously reads the local feature code.

[0081] Step S202: Following step S200, the logic processing unit of the energy storage coordination controller extracts the real-time data in the parsed message.

[0082] Step S204: Following step S202, the logic processing unit of the energy storage coordination controller combines the parsed real-time data with the local feature code to calculate the current verification code.

[0083] Furthermore, the entire system will distribute the corresponding feature codes to the devices in need. For example, if device 1 wants to send a message to the local device, and both device 1 and device 2 receive the message sent by the local device, then the entire system will give the local feature code to device 1, and device 1 and device 2 will give their feature codes to the local device.

[0084] Step S206: Following step S204, the logic processing unit of the energy storage coordination controller will parse and extract the check code in the current message.

[0085] Step S208: Following step S206, the logic processing unit of the energy storage coordination controller determines whether the calculated current check code is consistent with the check code extracted from the message.

[0086] Step S210: Continuing from step S208, the logic processing unit of the energy storage coordination controller determines that if the check codes are consistent, the real-time data of the message is reliable and valid, and proceeds to the next step of processing. If the check codes are inconsistent, the current message data is discarded and the parsing process of the next frame of the message continues.

[0087] An embodiment of this specification proposes a method for realizing reliable transmission control of digital messages by an energy storage coordination controller, which realizes high-speed processing of message data based on the SOC platform, and completes the function of reliable coordination control by adding message keys and feature codes. Abnormal message impacts may occur in the coordinated control system network, and abnormal situations such as malicious message attacks may also occur. For example, messages that comply with subscription rules are maliciously published in the network, so that the receiving device will not be able to resist the attack. In response to possible abnormal message impacts or malicious message attacks in the coordinated control system, the embodiment of this specification adds feature codes to the sent messages and parses and verifies the feature codes of the received messages in real time to resist possible anomalies in the network and realize reliable transmission and response of coordinated control system messages. The embodiment of this specification uses the example of key processing of real-time data in messages to illustrate a method for realizing reliable coordination control, which is suitable for key processing of real-time data in messages but is not limited to real-time data in messages.

[0088] Corresponding to the above method embodiment, this specification also provides an energy storage cooperative control system embodiment for realizing reliable transmission of messages. Figure 2 A schematic diagram of an energy storage cooperative control system for implementing reliable message transmission according to an embodiment of this specification is shown. Figure 2 As shown, the energy storage cooperative control system includes:

[0089] The determination module 201 is used to determine a sending device end for sending messages and a receiving device end for receiving messages among the multiple cooperative control devices and multiple PCS devices in the energy storage cooperative control system when messages need to be transmitted between the multiple cooperative control devices and multiple PCS devices in the energy storage cooperative control system;

[0090] The sending device 202 is used to obtain the real-time data to be transmitted to the receiving device, and to combine and process the real-time data with the device local feature code of the receiving device to obtain a check code; and to fill the real-time data and the check code with data according to the message format to obtain a current transmission message with the real-time data and the check code, and to send the current transmission message with the real-time data and the check code to the receiving device;

[0091] The receiving device end 203 is used to parse the current transmission message, extract the real-time data and the check code from the current transmission message, and combine the pre-stored device local feature code and the extracted real-time data to obtain the current check code; and use the current check code and the extracted check code to verify the safe transmission of the current transmission message, so as to realize the reliable transmission and response of the energy storage cooperative control system.

[0092] In the embodiment of the present specification, the receiving device end 203 is also used to use the local unique code of its device to calculate and save the device local feature code used for reliable message transmission, and publish the device local feature code to each sending device end respectively, so that each sending device end can save the device local feature code of the receiving device end into the device local feature code table.

[0093] To summarize, the master control or sub-control device (i.e., the auxiliary control device or PCS device) transmits the check code currently calculated in real time in the message to be sent. At the same time, the master control or sub-control receives the message data and calculates the check code in real time, which is matched with the check code transmitted in the message. The data with consistent check is reliable data and is processed in the next step. The data with inconsistent check is discarded to achieve reliable control of the auxiliary control.
