[0052] The specific embodiments of the application will be described in detail below with reference to the accompanying drawings.

[0053] Figure 1 A flowchart of an industrial Internet of Things data management method is provided according to an exemplary embodiment, in some embodiments, the industrial Internet of Things data management method is implemented by a management terminal, which can be one of at least one management terminal included in an industrial Internet of Things data management system, the system including an Internet of Things device data management platform, at least one management terminal, and an industrial Internet of Things device, the Internet of Things device data management platform being in communication connection with the at least one management terminal, and the at least one industrial Internet of Things device, as shown in Figure 1 The method comprises:

[0054] Step S101: In response to the data processing operation on the data file of the IoT device, send the corresponding IoT device data acquisition message.

[0055] In some embodiments, a client with IoT device data processing capabilities is deployed on the management terminal. Users can trigger data processing operations on IoT device data files by clicking on the data processing trigger unit displayed on the display module on the client. In response to the data processing operation on the IoT device data file, the client sends a corresponding IoT device data acquisition message to the IoT device data management platform. The data processing operation may include, for example, modifying data, adding data, querying data, and data cleaning, etc., and this disclosure does not limit the scope of the operation.

[0056] It should be noted that IoT device data can correspond to IoT device data files, which are encoded aggregates of IoT device data. In practice, the encoded data corresponding to the IoT device data is stored in an IoT device database. This database may or may not be managed by an IoT device data management platform. The IoT device data management platform can read the required IoT device data files from the IoT device database for forwarding.

[0057] In some embodiments, in response to a data processing operation on an IoT device data file, an authentication management system sends a corresponding IoT device data retrieval message, which carries an IoT device data file flag.

[0058] In practical implementation, the authentication management system can be integrated into the management terminal client. The client can use the authentication management system to perform operations such as sending IoT device data acquisition messages, acquiring encoded data, sending verification request messages, acquiring encoding functions, and decoding encoded data.

[0059] It should be noted that in the IoT device database, the encoded data corresponding to the IoT device data file is stored in association with the flag bit of the IoT device data file. This allows the IoT device data management platform to locate the corresponding encoded data based on the IoT device data file flag bit carried in the data acquisition request. For example, the flag bit and encoded data of the IoT device data file generated by the first IoT device are stored in association in the IoT device database, enabling the IoT device data management platform to locate the encoded data associated with the IoT device data file flag bit.

[0060] Step S102: Obtain the returned encoded data.

[0061] The encoding front end of the encoded data includes the data location flag bit of the corresponding IoT device data management platform, and the encoded data segment of the encoded data includes IoT device data.

[0062] In some embodiments, encoded data returned based on the flag bit of the IoT device data file is obtained; wherein, the encoded data is obtained by decoding the IoT device data file to obtain the IoT device data; the IoT device data is encoded by an encoding function, and the encoding function flag bit of the corresponding encoding function and the data location flag bit of the IoT device data management platform are entered into the encoding front end, and the encoding front end and the encoded IoT device data are encoded and aggregated.

[0063] In some embodiments, the data encoding program can obtain encoded data in the following ways: First, a private encoding function, a public encoding function, encoding function generation parameters, and encoding function flags are created, and an encoding function is generated from the encoding function generation parameters and encoding function flags. This encoding function is used to encode and protect IoT device data. Then, the encoding function flags, the data location flags of the IoT device data management platform, and the data version information are stored in the encoding front-end, and the encoding front-end is identified according to the private encoding function. Finally, the IoT device data is encoded, and the encoded IoT device data is aggregated together with the encoding front-end into encoded data in the target data format.

[0064] Step S103: Send a verification request message for the corresponding IoT device data file based on the data location flag.

[0065] In practice, the management terminal can first query locally whether a valid encoding function exists. If it does, it can directly search for the encoding function of the encoded data from the management terminal system. If the query fails, it can access the IoT device data management platform based on the data location flag and send a verification request message for the corresponding IoT device data file to the IoT device data management platform.

[0066] In some embodiments, the management terminal may send a verification request message for the corresponding IoT device data file in the following manner: obtain the management terminal identifier parameter of the management terminal corresponding to the data processing operation; send a verification request message carrying the encoding function flag bit and the management terminal identifier parameter to the IoT device data management platform, so as to perform data management authentication verification according to the management terminal identifier parameter, and return the encoding function corresponding to the encoding function flag bit after the authentication is completed.

[0067] In actual implementation, the management terminal determines a management terminal identification parameter, and obtains an encoding function flag bit from a pre-encoding section of the encoded data, and then generates a verification request message corresponding to the data file of the Internet of Things device according to the management terminal identification parameter and the encoding function flag bit, and sends the verification request message to the data management platform of the Internet of Things device. The data management platform of the Internet of Things device determines whether the management terminal has the right to process the data file of the Internet of Things device according to the management terminal identification parameter, and if so, obtains the encoding function corresponding to the encoding function flag bit from the encoding function database; otherwise, returns a request failure information.

[0068] For example, for the data file of the Internet of Things device that only the authorized terminal has the right to process, the data management platform of the Internet of Things device matches the management terminal identification parameter with the terminal identification parameters in the authorized terminal data table to determine whether the management terminal is the authorized terminal, and if so, obtains the encoding function corresponding to the encoding function flag bit and returns to the management terminal.

[0069] In some embodiments, the management terminal can directly send the pre-encoding section of the encoded data together with the management terminal identification parameter to the data management platform of the Internet of Things device, and the data management platform of the Internet of Things device generates an encoding function corresponding to the encoding function corresponding to the encoding function flag bit in the pre-encoding section of the encoded data and the encoding function generation parameter received from the client, for decoding operation.

[0070] Step S104, obtaining the returned encoding function corresponding to the encoded data.

[0071] The encoding function is returned by the data management platform of the Internet of Things device after completing the data management authentication verification according to the verification request message.

[0072] Step S105, decoding the encoded data according to the returned encoding function to obtain the data of the Internet of Things device.

[0073] In actual implementation, the management terminal can store the returned encoding function in the local terminal to directly search the encoding function from the management terminal system when next time data processing of the data file of the Internet of Things device is needed. It should be noted that the obtained encoding function is provided with permission, such as data processing times, start and end time, etc. When the data processing times are exceeded or the permission time is exceeded, the encoding function is invalid.

[0074] In some embodiments, the management terminal can obtain the data of the Internet of Things device by the following way: performing integrity check on the encoded data to obtain the data of the Internet of Things device after data encoding; and decoding the data of the Internet of Things device after data encoding according to the returned encoding function to obtain the data of the Internet of Things device after decoding operation.

[0075] In actual implementation, since the encoded data includes the pre-encoding segment and the encoded data segment, here, the integrity of the encoded data segment is checked, and when the complete data encoded Internet of Things device data is obtained, the data encoded Internet of Things device data is decoded according to the returned encoding function.

[0076] In some embodiments, the management terminal can obtain the Internet of Things device data by the following manner: searching for a management terminal encoding function corresponding to the encoded data in the management terminal system; fusing the management terminal encoding function and the returned encoding function as parameters to obtain a target encoding function; and decoding the encoded data according to the target encoding function.

[0077] In actual implementation, when the Internet of Things device data management platform sends the encoding function to the management terminal, there is a possibility of interception, and if the encoding function is intercepted by hackers, the encoded data can be decoded to obtain the Internet of Things device data file. By dividing the encoding function into two parts, one part is stored in the Internet of Things device data management platform, and the other part is stored locally in the management terminal. When decoding the encoded data, the encoding function needs to be obtained from the Internet of Things device data management platform first, and then the locally stored encoding function is obtained. Then, the two parts of the encoding function are fused as parameters to obtain a target encoding function, so as to decode the encoded data by using the target encoding function. In this way, since the two parts of the encoding function must be obtained at the same time to decode the encoded data, the security of the encoding function can be effectively enhanced.

[0078] Step S106, using the data management client to perform data processing on the Internet of Things device data.

[0079] Since the data encoded Internet of Things device data has been decoded, the data management client obtains the unencoded Internet of Things device data, and thus the data management client can perform data processing on the Internet of Things device data.

[0080] In some embodiments, the management terminal can perform data processing on the Internet of Things device data by the following manner: encoding and aggregating the Internet of Things device data into an Internet of Things device data file in a target data format; and using the data management client to perform data parsing and data processing on the Internet of Things device data file in the target data format.

[0081] The Internet of Things device data can be encoded and aggregated into an Internet of Things device data file in a target data format that can be read by the terminal application program, and then the data management client is used to enable the terminal application program to obtain the Internet of Things device data file in the target data format from the client to perform data parsing and data processing on the Internet of Things device data file in the target data format.

[0082] For example, the initially acquired Internet of Things device data can be inconvenient-to-handle data in a json format, and the json format Internet of Things device data can be changed into easy-to-handle EXCLE documents through encoding aggregation.

[0083] In the embodiments of the present disclosure, the management terminal sends an Internet of Things device data acquisition message to the Internet of Things device data management platform in response to a data processing operation on the Internet of Things device data file, so that the Internet of Things device data management platform sends encoded Internet of Things device data, authenticates the management terminal according to the authentication request message, and sends the encoding function after the authentication is completed. The management terminal can decode the encoded data according to the encoding function to obtain decoded Internet of Things device data and further implement processing on the Internet of Things device data, thereby effectively ensuring the security performance of the Internet of Things device data.

[0084] Based on the same inventive concept, the present disclosure also provides an industrial Internet of Things data management method as shown in Figure 2 The flowchart of an industrial Internet of Things data management method according to an exemplary embodiment shown in FIG. 1 can be applied to an Internet of Things device data management platform, which can be an Internet of Things device data management platform included in an industrial Internet of Things data management system. The system includes an Internet of Things device data management platform, at least one management terminal, and an industrial Internet of Things device. The Internet of Things device data management platform is in communication connection with the at least one management terminal and the at least one industrial Internet of Things device, respectively.

[0085] It can be understood that since the Internet of Things device data management platform, the management terminal, and the industrial Internet of Things device can jointly constitute the industrial Internet of Things data management system, the management terminal can be used to execute the steps of the method described above. Figure 1 Correspondingly, the Internet of Things device data management platform can be used to execute the steps as shown in Figure 2 The method includes the steps as shown in Figure 2 The method includes the steps as shown in

[0086] Step S201, acquiring an Internet of Things device data acquisition message, the Internet of Things device data acquisition message being sent by a management terminal in response to a data processing operation on an Internet of Things device data file.

[0087] Step S202, sending encoded data, the pre-encoding segment of the encoded data including a data location flag corresponding to the Internet of Things device data management platform, and the encoded data segment of the encoded data including Internet of Things device data.

[0088] Step S203, acquiring an authentication request message corresponding to the Internet of Things device data file, the authentication request message being sent by the management terminal according to the data location flag.

[0089] Step S204, after the data management authentication verification according to the verification request message is completed, the encoding function corresponding to the encoded data is sent.

[0090] The encoding function is used to manage the terminal to decode the encoded data according to the returned encoding function, and obtain the Internet of Things device data; and use the data management client to process the Internet of Things device data.

[0091] Optionally, the Internet of Things device data acquisition message is sent by the authentication management system in response to the data processing operation of the Internet of Things device data file, and the Internet of Things device data acquisition message carries an Internet of Things device data file flag bit.

[0092] Optionally, the step S202 of sending the encoded data comprises:

[0093] The Internet of Things device data file is decoded to obtain the Internet of Things device data.

[0094] The Internet of Things device data is encoded by the encoding function, and the encoding function flag bit corresponding to the encoding function and the data position flag position of the Internet of Things device data management platform are entered into the encoding segment, the encoding segment and the Internet of Things device data after data encoding are aggregated to obtain the encoded data.

[0095] The encoded data is sent according to the Internet of Things device data file flag bit.

[0096] Optionally, the step S203 of acquiring the verification request message corresponding to the Internet of Things device data file comprises:

[0097] The verification request message carrying the encoding function flag bit and the management terminal identification parameter is acquired.

[0098] The data management authentication verification is performed according to the management terminal identification parameter, and the encoding function corresponding to the encoding function flag bit is sent after the authentication is completed.

[0099] Based on the flowchart of the industrial Internet of Things data management method shown in the above Figure 1 and Figure 2 In one specific embodiment, the industrial Internet of Things data management method provided by the embodiment of the present application comprises:

[0100] 1) The Internet of Things device data management platform acquires the Internet of Things device data generated by the industrial Internet of Things device.

[0101] 2) The Internet of Things device data management platform encodes the Internet of Things device data through an encoding function, and enters the encoding function flag bit of the encoding function and the data location flag bit of the Internet of Things device data management platform into the pre-encoding section.

[0102] In actual implementation, after the Internet of Things device data is encoded through the encoding function, the encoding function flag bit, the data location flag bit of the Internet of Things device data management platform, and the data version information are stored in the pre-encoding section, and the pre-encoding section is identified according to the secret encoding function.

[0103] 3) The Internet of Things device data management platform aggregates the pre-encoding section and the Internet of Things device data after data encoding to obtain encoded data.

[0104] Among them, the Internet of Things device data after data encoding can be aggregated with the pre-encoding section into encoded data in a target data format.

[0105] 4) The Internet of Things device data management platform stores the encoded data into the Internet of Things device database of the Internet of Things device data management platform.

[0106] Among them, the encoded data can be stored in association with the data location flag bit in the Internet of Things device database.

[0107] 5) The Internet of Things device data management platform stores the encoding function and the encoding function flag bit in association in the Internet of Things device database of the Internet of Things device data management platform.

[0108] 6) The management terminal obtains a data processing operation for the Internet of Things device data file.

[0109] 7) The management terminal sends an Internet of Things device data acquisition message carrying the data location flag bit.

[0110] Among them, the management terminal can send the corresponding Internet of Things device data acquisition message through the authentication management system in response to the data processing operation.

[0111] 8) The Internet of Things device data management platform sends the encoded data corresponding to the data location flag bit.

[0112] Among them, the Internet of Things device data management platform can obtain the corresponding encoded data through the data location flag bit, and send the encoded data to the management terminal.

[0113] 9) The management terminal sends a verification request message carrying a management terminal identification parameter and an encoding function flag bit.

[0114] 10) The Internet of Things device data management platform performs data management authentication verification according to the management terminal identification parameter.

[0115] For example, for IoT device data files that only authorized terminals have the authority to process, the IoT device data management platform will match the management terminal identification parameter with the terminal identification parameter in the data table to determine whether the management terminal is an authorized terminal.

[0116] 11) After authentication is completed, the IoT device data management platform returns the encoding function with the corresponding encoding function flag bit.

[0117] 12) The management terminal performs integrity verification on the encoded data to obtain the IoT device data with data encoding.

[0118] 13) The management terminal decodes the encoded IoT device data using the returned encoding function to obtain the decoded IoT device data.

[0119] 14) The management terminal uses the data management client to process and decode the IoT device data.

[0120] In practice, the management terminal encodes and aggregates IoT device data to obtain IoT device data files, and the data management client enables the data processor to parse and process the IoT device data files.

[0121] Based on the same inventive concept, this disclosure also provides, for example Figure 3 The diagram shown illustrates an industrial Internet of Things (IoT) data management system according to an exemplary embodiment, as follows: Figure 3 As shown, the system includes an IoT device data management platform 310, at least one management terminal 320, and at least one industrial IoT device 330.
