[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] In related technologies, the edge side can achieve mutual collaboration, for example, when the first edge device is fully loaded, the second edge device can collaborate with the second edge device to process data. The second edge device can migrate the sensory data it collects to the first edge device, and the first edge device can collaborate with the sensory data that originally needed to be processed by the second edge device. This method alleviates the data processing pressure on the edge side to a certain extent, making the load conditions of the edge devices on the edge side roughly the same. However, this is only a relatively basic mutual collaborative processing, and it is difficult to achieve data intercommunication and sharing on the edge side.

[0048] Data processing at the edge typically involves data cleaning and simple calculations. Complex calculations are required to accurately identify correlations between data. Typically, devices at the edge simply process the sensory data they collect, obtaining very basic or even invalid information that can be used by users. If it is necessary to identify correlations between sensory data collected by different devices at the edge to obtain more relevant information, the processed data must be uploaded to processing equipment closer to the center for data security considerations. However, the devices closer to the center face a large amount of data and a heavy processing load, posing a challenge to the computing power of the devices at the center.

[0049] To this end, an embodiment of the present application proposes an edge computing method for a digital cloud, which can at least enable edge devices to share their processed basic data while ensuring data security, thereby enabling more useful information that can be used by users to be mined on the edge side, and reducing the processing load of equipment on the center side.

[0050] Reference Figure 1 As shown, the edge computing method of the present application is illustrated using a first edge device 100, a second edge device 300, and a central cloud 200 as the simplest architecture. In this embodiment, the first edge device 100 is used to obtain basic data from the second edge device 300. The basic data of the second edge device 300 is data obtained by the second edge device 300 after processing the acquired data, which is typically stored in the second edge device 300. The first edge device 100 calculates the collected perception data in combination with the processed basic data from the second edge device 300 to obtain a calculation result.

[0051] Reference Figure 2 As shown, the present application provides an edge computing method for a digital cloud, which is applied to a first edge device 100, including:

[0052] S100, acquiring perception data;

[0053] S200, obtaining basic data required for the perception data based on the perception data;

[0054] S300, obtaining a second edge device 300 corresponding to the basic data;

[0055] S400 , attempting to directly obtain basic data from a second edge device 300 corresponding to the basic data;

[0056] S500: If the basic data is not directly obtained from the second edge device 300, a request message is sent to the central cloud 200; the request message is used by the central cloud 200 to send an instruction signal to the second edge device 300;

[0057] S600: Acquire basic data sent by the second edge device 300 based on the indication signal;

[0058] S700: Calculate the perception data and the basic data to obtain a calculation result.

[0059] In the technical solution of the embodiment of the present application, the first edge device 100 obtains the perception data and obtains the basic data required for the joint calculation of the perception data; then the second edge device 300 where the basic data is stored is determined based on the basic data; the first edge device 100 attempts to obtain the basic data from the second edge device 300; when the basic data is not obtained from the second edge device 300, a request message is sent to the central cloud 200 to obtain the basic data from the second edge device 300 through the central cloud 200 in coordination with the first edge device 100 to increase the security of the basic data; in an embodiment, the central cloud 200 sends an indication signal to the second edge device 300 based on the request message, and the second edge device 300 sends the basic data to the first edge device 100, and then the first edge device 100 calculates the obtained perception data and the basic data of the second edge device 300 to obtain a calculation result.

[0060] It should be noted that, in the embodiment, the layout system includes a plurality of edge devices. The edge device that requests basic data is the first edge device, and the other edge devices are all second edge devices.

[0061] In some embodiments, for data security reasons, when the first edge device 100 attempts to obtain basic data from the second edge device 300, the second edge device 300 refuses to send the basic data directly to the first edge device 100 based on the security level of the basic data. In this case, the first edge device 100 sends a request message through the central cloud 200, and the central cloud 200 sends an instruction signal to the second edge device 300 based on the request message. The second edge device 300 then sends the basic data to the first edge device 100 based on the instruction signal, thereby improving the protection of the basic data.

[0062] In some embodiments, to improve the protection of basic data, as an optional implementation of the above embodiment, the calculating the perception data and the basic data to obtain the calculation result includes:

[0063] Obtain the encrypted basic data and its encryption identifier;

[0064] Obtain the decryption identifier sent by the central cloud 200;

[0065] Decrypting the encrypted basic data based on the encryption identifier and the decryption identifier;

[0066] Calculation is performed on the perception data and the encrypted basic data.

[0067] In an embodiment, when the second edge device 300 sends basic data to the first edge device 100 based on the indication signal, it also encrypts the basic data and generates an encryption identifier; the central cloud 200 generates a decryption identifier corresponding to the encrypted representation and sends it to the first edge device 100; the first edge device 100 decrypts the encrypted basic data based on the encryption identifier and the decryption identifier to obtain the decrypted basic data, and then calculates the perception data and the decrypted basic data. In an embodiment, when the central cloud 200 sends an indication signal to the second edge device 300, it also sends an encryption scheme to the second edge device 200. The second edge device 300 encrypts the basic data based on the encryption scheme and generates an encryption identifier. The central cloud then sends the decryption identifier corresponding to the encryption scheme to the first edge device.

[0068] In other words, when the second edge device 300 does not directly send the basic data to the first edge device 100, it indicates that the basic data has a higher security level. In this case, the central cloud 200 coordinates and processes the basic data. The second edge device 300 encrypts the basic data and generates an encryption identifier. The central cloud 200 then sends the decryption identifier to the first edge device 100. The first edge device 100 decrypts the basic data based on the encryption and decryption identifiers, thereby achieving edge-side data sharing while ensuring data security.

[0069] As an optional implementation of the above embodiment, the step of attempting to directly obtain basic data from the second edge device 300 corresponding to the basic data includes:

[0070] Determine a target interface combination of the first edge device 100 and the second edge device 300;

[0071] Determining a communication order of multiple target interfaces based on the target interface combination; wherein the communication order is arranged from low to high according to the security level of the target interface;

[0072] Attempt to communicate with the second edge device 300 in sequence through the multiple target interfaces in the communication order, so as to attempt to obtain basic data from the second edge device 300 through the multiple target interfaces in the communication order.

[0073] In this embodiment, taking into account deployment costs, processing capabilities, and security considerations, multiple target interfaces are deployed between the first edge device 100 and the second edge device 300, and the target interfaces have different security levels. The first edge device 100 accesses the target interfaces in order of security level, attempting to obtain basic data from the target interfaces with the highest security level.

[0074] That is, for example, in an embodiment, a first target interface, a second target interface, and a third target interface are provided between the first edge device 100 and the second edge device 300 from low to high; the first edge device 100 attempts to obtain basic data from the first target interface, the second target interface, and the third target interface in turn.

[0075] As an optional implementation manner of the above embodiment, the attempting to communicate with the second edge device 300 in sequence through the multiple target interfaces in the communication order includes:

[0076] Attempt to communicate with the second edge device 300 through the current target interface;

[0077] If the current target interface has not established communication with the second edge device 300, determining whether the current target interface has the lowest communication order among the multiple target interfaces;

[0078] If the current target interface is not the one with the lowest communication order among the multiple target interfaces, an attempt is made to communicate with the second edge device 300 through the next target interface of the current target interface.

[0079] As an optional implementation manner of the above embodiment, the attempting to communicate with the second edge device 300 in sequence through the multiple target interfaces in the communication order further includes:

[0080] If the current target interface has the lowest communication order among the multiple target interfaces, the basic data is not directly obtained from the second edge device 300 .

[0081] Because in the embodiment, if the first edge device 100 does not obtain the basic data through the current target interface, and the current target interface has the lowest communication order among the multiple target interfaces, then the current target interface has the highest security level among the multiple target interfaces, and the basic data is not obtained directly from the second edge device 300.

[0082] As an optional implementation manner of the above embodiment, if the current target interface has not established communication with the second edge device 300, after determining whether the current target interface is the one with the lowest communication order among the multiple target interfaces, the attempting to communicate with the second edge device 300 in sequence through the multiple target interfaces in the communication order further includes:

[0083] Communication is established with the second edge device 300 through the current target interface to obtain the basic data from the second edge device 300 through the current target interface.

[0084] For example, in an embodiment, a first target interface, a second target interface, and a third target interface are provided between the first edge device 100 and the second edge device 300 from low to high; the first edge device 100 attempts to obtain basic data from the first target interface, the second target interface, and the third target interface in turn.

[0085] The first edge device 100 first attempts to obtain the basic data through the first target interface. If the basic data corresponds to the security level of the first target interface, the first edge device 100 obtains the basic data through the first target interface. If not, the first edge device 100 then attempts to obtain the basic data through the second target interface. If the basic data corresponds to the security level of the second target interface, the first edge device 100 obtains the basic data through the second target interface. If not, the first edge device 100 then attempts to obtain the basic data through the third target interface. If the basic data corresponds to the security level of the third target interface, the first edge device 100 obtains the basic data through the third target interface. If not, since the third target interface has the highest security level, the first edge device 100 fails to obtain the basic data through the first, second, and third target interfaces. In this case, the first edge device 100 attempts to obtain the data directly but fails. In this case, the request information is sent to the central cloud 200, which coordinates and processes the data.

[0086] As an optional implementation manner of the above embodiment, obtaining basic data required for the perception data based on the perception data includes:

[0087] Get deployment protocol information;

[0088] Based on the deployment protocol information, obtaining computing type information of the perception data and basic data identification information corresponding to the computing type information;

[0089] Based on the basic data identification information, basic data required for the perception data is determined.

[0090] That is, in the embodiment, identification information of the perception data and its corresponding basic data is set in the first edge device 100; when the first edge device 100 obtains the perception data, it determines the basic data required for the perception data according to its calculation type information.

[0091] In some embodiments, the second edge device 300 where the basic data is located may also be determined based on the deployment protocol information.

[0092] Reference Figure 1 As shown, the communication channel between the first edge device 100 and the second edge device 300 includes a first communication channel 10 and a second communication channel 23. The first communication channel 10 is used as a bidirectional channel for the first edge device 100 and the second edge device 300. The first edge device 100 attempts to obtain basic data through the first communication channel. If the basic data meets the security requirements of the second edge device 300, the second edge device 300 sends the basic data to the first edge device 100 through the first communication channel. If the basic data does not meet the security requirements of the second edge device 300, the second edge device 300 rejects the attempt of the first edge device 100. At this time, the first edge device 100 sends a request message to the central cloud 200 through the third communication channel 21. The central cloud 200 sends an indication signal to the second edge device 300 through the fourth communication channel 22. Based on the indication signal, the second edge device 300 sends the basic data (encrypted basic data and encryption identifier) ​​to the first edge device 100 through the second communication channel. In an embodiment, the second communication channel is a dedicated channel for the second edge device 300 to transmit basic data to the first edge device 100 , has the highest security level, and is a one-way communication channel to improve the security and confidentiality of the basic data.

[0093] Furthermore, the central cloud 200 also sends a decryption identifier to the first edge device 100 through the third communication channel.
