[0032] An embodiment of the present disclosure provides a data transmission method, which is applied to a data sending end, comprising: determining a data source of the target data in response to target data uploaded by a data acquisition component, wherein the data acquisition component is used to collect information on the physical protection system of a nuclear power plant; encrypting the target data based on the data source to obtain data to be transmitted; and displaying the data to be transmitted and a transmission sequence number corresponding to the data to be transmitted on a data display component, so that after a data capture component of a data receiving end detects the transmission sequence number displayed on the data display component, it receives and parses the data to be transmitted to determine the target data; wherein the data receiving end receives and parses the data to be transmitted to determine the target data, comprising: in response to the data capture component detecting the transmission sequence number displayed on the data display component, capturing the displayed content; and parsing the displayed content to determine the target data.

[0033] Figure 1 The application scenario diagram of the data transmission method, apparatus, device, medium and program product according to the embodiments of the present disclosure is schematically shown.

[0034] like Figure 1 As shown, the application scenario 100 according to this embodiment may include a nuclear power plant physical protection system 110, a data transmitter 120, and a data receiver 130. The data transmitter includes a data acquisition component 121, a first processor 122, and a data display component 123, and the data receiver 130 includes a data capture component 131 and a second processor 132. The data acquisition component 121 and the nuclear power plant physical protection system 110 are connected via a network. The data capture component 131 monitors the data display component 123 and, when data is displayed on the data display component 123, captures the displayed content.

[0035] The data sending end 120 acquires data from the nuclear power plant physical protection system 110 using the data acquisition component 131 , processes the acquired data using the first processor 122 , and displays the processing results on the data display component 123 .

[0036] The data receiving end 130 uses the data capture component 131 to monitor and capture the content displayed by the data display component 123. When the information is captured, the second processor 132 is used to process the captured information, and the data obtained by the data acquisition component 131 from the nuclear power plant physical protection system 110 is restored to complete the data transmission.

[0037] It should be understood that Figure 1 The number of nuclear power plant physical protection systems, data transmitters, data receivers, data acquisition components, first processors, data display components, data capture components, and second processors in the embodiment is merely illustrative. Any number of nuclear power plant physical protection systems, data transmitters, data receivers, data acquisition components, first processors, data display components, data capture components, and second processors may be provided as required.

[0038] The following will be based on Figure 1 The scene described by Figures 2 to 4 The data transmission method according to the embodiment of the present disclosure is described in detail.

[0039] Figure 2 The flowchart of the data transmission method according to the embodiment of the present disclosure is schematically shown.

[0040] like Figure 2 As shown, the data transmission method of this embodiment includes operations S210 to S230.

[0041] In operation S210 , in response to target data uploaded by the data acquisition component, a data source of the target data is determined.

[0042] According to embodiments of the present disclosure, a data acquisition component is used to collect information from a nuclear power plant's physical protection system. The data sources for this information may include information on entrances and exits related to management areas, access authorization and approval, access control, equipment management, fire protection systems, and video systems. By analyzing the data type of the target data, the data source can be determined.

[0043] According to the embodiments of the present disclosure, the data acquisition component can obtain target data from different data sources of the nuclear power plant physical protection system through means such as inter-system interface docking, message subscription, and reading database files. Multiple target data can be classified according to the different data sources to which they belong, and prioritized according to the data types and data contents of the multiple target data. The data acquisition component will upload and process target data with higher priority according to the priority of the target data.

[0044] In operation S220 , the target data is encrypted based on the data source to obtain data to be transmitted.

[0045] According to the embodiments of the present disclosure, different data sources correspond to different encryption methods. These methods include encoding rules for data encoding and a data header representing the data source that needs to be added when encapsulating the target data. Based on the data source to which the target data belongs, the corresponding encryption method is selected and processed to obtain the data to be transmitted.

[0046] In operation S230, the data to be transmitted and the transmission sequence number corresponding to the data to be transmitted are displayed on the data display component, so that after the data capture component at the data receiving end detects the transmission sequence number displayed on the data display component, it receives and parses the data to be transmitted to determine the target data.

[0047] According to an embodiment of the present disclosure, the transmission sequence number can be used to represent the order of the data to be transmitted in the transmission queue, so that the data receiving end can determine whether the currently displayed data to be transmitted is unreceived data.

[0048] According to an embodiment of the present disclosure, the data receiving end receives and parses the data to be transmitted and determines the target data, including: in response to the data capture component detecting the transmission sequence number displayed on the data display component, capturing the displayed content; and parsing the displayed content to determine the target data.

[0049] According to an embodiment of the present disclosure, the displayed content includes a transmission sequence number and data to be transmitted. When the data receiving end determines that the transmission sequence number indicates that the current data to be transmitted is data that has not been received locally, the displayed content on the data display component is captured, and the data to be transmitted in the displayed content is determined. The data to be transmitted is processed using methods such as data decryption to determine the target data.

[0050] According to an embodiment of the present disclosure, a data transmitter uses a data acquisition component to collect data from a nuclear power plant's physical protection system. After obtaining target data, the transmitter determines the target data's data source and encrypts the target data using an encryption method corresponding to the data source to obtain the data to be transmitted. Furthermore, a transmission sequence number is determined based on the target data and the data source. The transmission sequence number and the data to be transmitted are displayed on the data display component, allowing the data receiver to detect and capture the content on the data display component and further perform data analysis and decryption to obtain the target data. Because the target data is encrypted locally at the transmitter before being displayed, the displayed content is ensured to be non-plaintext, preventing target data leakage and improving data security. Because the encryption method and transmission sequence number are both determined based on the data source, the receiver can also determine the data source by analyzing the displayed content and decrypt it using a decryption method corresponding to the data source to restore the target data, ensuring the accuracy of data transmission. Furthermore, data transmission through data display and data capture eliminates the need for a stable network connection between the transmitter and receiver, improving data transmission stability when network quality is unreliable.

[0051] According to an embodiment of the present disclosure, target data is encrypted based on a data source to obtain data to be transmitted, including: based on the data source, transmission information corresponding to the data source is added to the target data to obtain data to be encrypted; and the data to be encrypted is encrypting using a public key of asymmetric encryption to obtain data to be transmitted.

[0052] According to embodiments of the present disclosure, a data header can include transmission information. This transmission information is added to the target data as a data header, enabling analysis of the encrypted data to identify the data source. Asymmetric encryption involves a pair of corresponding public and private keys, with the public key stored at the data transmitter and the private key stored at the data receiver. The encrypted data is encrypted using the public key to obtain the data to be transmitted.

[0053] According to an embodiment of the present disclosure, based on the data source, transmission information is added to the target data and encrypted using a public key, so that after receiving the data, the data receiving end can use the decryption method corresponding to the data source to parse and decrypt the data to obtain the target data, thereby improving the security and accuracy of data transmission.

[0054] According to an embodiment of the present disclosure, displaying the data to be transmitted and the transmission sequence number corresponding to the data to be transmitted on a data display component includes: determining the transmission sequence number of the data to be transmitted based on the data to be transmitted and the data source; determining the display content based on the data to be transmitted and the transmission sequence number; and displaying the display content on the data display component.

[0055] According to an embodiment of the present disclosure, a transmission sequence number may include a sequence number of the data to be transmitted and a tag representing the data source to which the data to be transmitted belongs. The sequence number is used to represent the order of the data to be transmitted. For example, if the data to be transmitted is the 25th data item and the data source to which it belongs is marked as b, the transmission sequence number of the data to be transmitted may be b25.

[0056] According to an embodiment of the present disclosure, the display content includes the data to be transmitted and the transmission sequence number, so the display content can be obtained by splicing the data to be transmitted and the transmission sequence number according to the format requirements.

[0057] According to an embodiment of the present disclosure, by displaying display content determined based on the transmission sequence number and the data to be transmitted on a data display component, it is possible to ensure that the data receiving end can determine the transmission sequence number based on the received display content, thereby determining the data source of the target data, and further decrypt the data to be transmitted based on the data source, thereby ensuring the transmission accuracy of the target data.

[0058] According to an embodiment of the present disclosure, in response to target data uploaded by a data acquisition component, determining the data source of the target data includes: determining a data type corresponding to the target data based on the target data; and determining the data source based on the data type and the correspondence between the data type and the data source.

[0059] According to an embodiment of the present disclosure, since the data generated by different data sources correspond to different data types, the data source to which the target data belongs can be determined based on the data type corresponding to the target data, so that the corresponding encryption algorithm or data source label can be selected based on the data source.

[0060] According to the embodiments of the present disclosure, by determining the data type of the target data, it is possible to accurately determine the data source to which the target data belongs, further determine the appropriate encryption algorithm or data source tag and process the target data, and ensure that the data to be transmitted obtained after processing can be accurately received and decrypted by the data receiving end.

[0061] Figure 3 The following schematically shows a flow chart of a data transmission method according to another embodiment of the present disclosure.

[0062] like Figure 3 As shown, the data transmission method of this embodiment includes operations S310 to S330.

[0063] In operation S310, a data display component of a data sending end is detected using a data capture component.

[0064] According to an embodiment of the present disclosure, the data capture component may include an image acquisition device such as a camera and a processor, wherein the image acquisition device is used to capture the display status of the data display component at the data sending end and send it to the processor, and the processor is used to perform image processing on the captured display status to determine whether the transmission sequence number is displayed on the data display component.

[0065] In operation S320 , in response to the data capture component detecting that the transmission sequence number is displayed on the data display component, the display content on the data display component is captured.

[0066] According to an embodiment of the present disclosure, when a processor is used to perform image processing and determine the display transmission sequence number of the current data display component, an image acquisition device is used to obtain the display content on the data display component.

[0067] In operation S330 , the displayed content is parsed to determine target data.

[0068] According to an embodiment of the present disclosure, the displayed content is parsed, thereby determining the data to be transmitted based on the displayed content and the transmission sequence number determined in operation S320, and decrypting the data to be transmitted to obtain the target data.

[0069] According to an embodiment of the present disclosure, the display content is displayed on the data display component through the following operations: the data sending end determines the data source of the target data in response to the data acquisition component uploading the target data; based on the data source, the target data is encrypted to obtain the data to be transmitted; and the data to be transmitted and the transmission sequence number corresponding to the data to be transmitted are displayed on the data display component.

[0070] According to the embodiments of the present disclosure, by using a data capture component to detect and capture a data display component, data transmission and communication can be performed without a network connection, reducing dependence on network quality and improving the stability of data transmission.

[0071] According to an embodiment of the present disclosure, parsing the displayed content to determine the target data includes: parsing the displayed content to determine the data to be transmitted; and using a data decryption method corresponding to the data encryption performed by the data sending end to decrypt the data to be transmitted to obtain the target data.

[0072] According to an embodiment of the present disclosure, the displayed content includes the data to be transmitted and a transmission sequence number. After determining the displayed content, the data to be transmitted can be determined based on the known transmission sequence number. The data to be transmitted can be parsed to determine the data source to which the target data corresponding to the data to be transmitted belongs. The data to be transmitted can then be decrypted using the encryption method and decryption method corresponding to the data source and the decryption method.

[0073] According to an embodiment of the present disclosure, the data to be transmitted and the transmission sequence number in the display content are separated so that the decryption method for the data to be transmitted can be determined based on the transmission sequence number, thereby completing the decryption of the data to be transmitted, improving the efficiency of network transmission and ensuring that the correct decryption method is selected to obtain the correct target data.

[0074] According to an embodiment of the present disclosure, a data decryption method corresponding to that used when data is encrypted by a data sending end is used to decrypt the data to be transmitted to obtain target data, including: using an asymmetric encryption private key to decrypt the data to be transmitted to obtain the data to be encrypted, wherein the asymmetric encryption private key corresponds to the asymmetric encryption public key used when the data sending end encrypts the data; determining the data source of the target data based on the transmission sequence number; and using transmission information corresponding to the data source to process the encrypted data to obtain the target data.

[0075] According to an embodiment of the present disclosure, a decryption method corresponding to a data source is obtained, wherein the decryption method includes a private key for asymmetric encryption. Since the private key corresponds to the public key used for encryption, the private key can be used to decrypt the data to be transmitted to obtain the data to be encrypted.

[0076] According to an embodiment of the present disclosure, by analyzing the transmission sequence number, the data source corresponding to the data to be transmitted or the target data can be determined, thereby removing the transmission information corresponding to the data source from the data to be encrypted to obtain the target data.

[0077] According to an embodiment of the present disclosure, after selecting a data decryption method through a data source, the asymmetric encryption private key and the transmission information corresponding to the data source can be determined, so that the private key can be used to decrypt the data to be transmitted, and the transmission information can be eliminated from the obtained data to be encrypted to obtain the target data.

[0078] Figure 4 The interactive process of the data transmission method according to an embodiment of the present disclosure is schematically illustrated.

[0079] like Figure 4 As shown, the interaction process includes operations S401 to S407.

[0080] In operation S401, the data transmitting end uses the data acquisition component to obtain target data from the nuclear power plant physical protection system. In operation S402, the data transmitting end determines the data source of the target data. In operation S403, the data transmitting end encrypts the target data. In operation S404, the data transmitting end determines the transmission sequence number and uses the data display component to display the transmission sequence number and target data. In operation S405, the data receiving end uses the data capture component to detect the data display component. In operation S406, if it is determined that the transmission sequence number is displayed on the data display component, the display content on the data display component is captured. In operation S407, the display content is parsed, the target data is determined, and the transmission of the target data is completed.

[0081] Based on the above data transmission method, the present disclosure also provides a data transmission device. Figure 5~Figure 6 The device is described in detail.
