[0027] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0029] Embodiment 1

[0030] Figure 1 A flowchart of a method for sending a model file is provided for the first embodiment of the present invention, which is applied to a cloud server with a mirroring service, such as Figure 1 As shown, the method includes:

[0031] S110: Convert the received model file into an image file.

[0032] S120: Storing the image file in the image service.

[0033] Regarding step S110 to step S120, specifically, the mirror service is a set of interfaces between the application / component and the server platform, so that the application / component can be conveniently deployed to the server for operation. The mirror service in this embodiment is responsible for storing and issuing mirror files.

[0034] It is understandable that the cloud server is responsible for mirroring the model. After receiving the model file uploaded by other devices, the cloud server mirrors the model file and sends it to the mirroring service.

[0035] S130: In response to the model delivery request, transmit the integration message to the edge device through the second information transmission channel.

[0036] Specifically, the integration information includes at least the attribute information of the mirror service and the attribute information of the mirror file. The attribute information of the mirror service includes at least the address information, user name and password information of the mirror service; the attribute information of the mirror file includes at least the name information and version information of the mirror file.

[0037] It is understandable that the model sending request is triggered by the user, and the user can trigger the model sending request in a variety of ways, such as sending a request instruction on the terminal device, or performing a key operation.

[0038] It is worth mentioning that the integration information in this embodiment can be encrypted. After receiving the integration information, the subsequent edge device needs to decrypt the integration information to obtain the attribute information of the mirror service, the name information of the mirror file, etc. In this way, the security of the model file distribution method is improved.

[0039] It should be noted that the cloud server in this embodiment also includes a message middleware; the transmission of the integrated message to the edge device through the second information transmission channel includes: transmitting the integrated message to the message middleware through the second information transmission channel; the message middleware sends the integrated message to the edge device. It can be understood that the message middleware uses an efficient and reliable message transmission mechanism to exchange platform-related data, and integrates distributed systems based on data communication; by providing message transmission and message queuing models, it can expand inter-process communication in a distributed environment. In this way, it can ensure that the edge device receives the integrated message, and improve the reliability of the method of issuing the model file.

[0040] It is worth mentioning that the message middleware in this embodiment is MQTT middleware. In addition, the message middleware can also be other types, such as message middleware based on TCP / TP protocol, and this embodiment does not specifically limit the type of message middleware.

[0041] S140: In response to the image file download request sent by the edge device according to the integrated message, the image file matching the image file download request is sent to the edge device through the first information transmission channel.

[0042] Specifically, after receiving the integration message, the edge device decompresses and decrypts the integration message, obtains the address, user name, password and image name of the image service to be downloaded, and uses this information to connect to the image service to obtain the image file returned by the image service.

[0043] It is worth mentioning that the first information transmission channel and the second information transmission channel in this embodiment are different information transmission channels.

[0044] Compared with the related art, the embodiments of the present invention have at least the following advantages: by converting the model file into a mirror file, the mirror file is transmitted through the first information transmission channel, and the integrated message is transmitted through the second information transmission channel, so that the transmission of messages and files has a dedicated channel, and the decoupling design of message and file information transmission is realized, ensuring that the message can maintain a high throughput, thereby improving the efficiency of information transmission; files and messages are transmitted in the form of data streams, so that there is no blockage and delay in the communication between the cloud server and each device, and the business response speed is fast and the performance is high; in addition, the mirror file is transmitted to the mirror service, that is, the model is mirrored and served, so that the model after the mirror service has low coupling and small disk space, which improves the superiority of the method for issuing model files.

[0045] Embodiment 2

[0046] Figure 2 This is a flow chart of a method for sending a model file provided in the second embodiment of the present invention. This embodiment is a further improvement of the previous embodiment. The main improvement is that before sending the integrated information to the edge device, it will also determine whether the edge device meets the message receiving conditions. In this way, the method for sending the model file is more orderly and reliable.

[0047] like Figure 2 As shown, the method includes:

[0048] S210: Convert the received model file into an image file.

[0049] S220: Store the image file in the image service.

[0050] Steps S210 to S220 of this embodiment are similar to steps S110 to S120 of the first embodiment, and are not described again here to avoid repetition.

[0051] S230: In response to the model sending request triggered by the user, determine whether the edge device meets the message receiving conditions; if so, execute step S250; if not, execute step S240.

[0052] Specifically, the message receiving condition of this embodiment may be whether the edge device is online, or other conditions, which may be set according to actual conditions. This embodiment does not specifically limit the message receiving condition.

[0053] S240: Integrate the message cache and monitor in real time within the preset cache time whether the edge device meets the message receiving conditions again. If the edge device is monitored to meet the message receiving conditions within the preset cache time, execute step S250; if the edge device is monitored to not meet the message receiving conditions within the preset cache time, execute step S260.

[0054] Specifically, the duration of the preset cache time can be set according to actual needs, and this embodiment does not specifically limit the duration of the preset cache time.

[0055] S250: Send the integrated message to the edge device.

[0056] S260: Clear the integrated message from the message middleware.

[0057] S270: In response to the image file download request sent by the edge device according to the integrated message, the image file matching the image file download request is sent to the edge device through the first information transmission channel.

[0058] Specifically, after the integrated message is cleared from the message middleware, the cloud server will also mark the integrated message as timeout information.

[0059] Compared with the related art, the embodiments of the present invention have at least the following advantages: by converting the model file into a mirror file, the mirror file is transmitted through the first information transmission channel, and the integrated message is transmitted through the second information transmission channel, so that the transmission of messages and files has a dedicated channel, and the decoupling design of message and file information transmission is realized, ensuring that the message can maintain a high throughput, thereby improving the efficiency of information transmission; files and messages are transmitted in the form of data streams, so that there is no blockage and delay in the communication between the cloud server and each device, and the business response speed is fast and the performance is high; in addition, the mirror file is transmitted to the preset mirror service, that is, the model is mirrored and served, so that the model coupling degree after the mirror service is low and the disk occupies less space, which improves the superiority of the method for sending the model file.

[0060] Embodiment 3

[0061] Figure 3 This is a flow chart of a method for sending a model file provided in the third embodiment of the present invention. This embodiment is a further improvement of the previous embodiment. The main improvement is that before sending the integrated information to the edge device, it is also determined whether the integrated message has timed out and whether the edge device meets the message receiving conditions. In this way, the method for sending the model file of this embodiment is more orderly and reliable.

[0062] like Figure 3 As shown, the method includes:

[0063] S310: Convert the received model file into an image file.

[0064] S320: Store the image file in the image service.

[0065] Steps S310 to S320 of this embodiment are similar to steps S110 to S120 of the first embodiment, and are not described again here to avoid repetition.

[0066] S330: Save the integrated message as a message to be sent to the internal message queue.

[0067] Specifically, the internal message queue is composed of multiple messages to be sent, and the multiple messages to be sent are arranged in the order of entering the internal message queue. The message to be sent at the end of the internal message queue is the last message to enter the internal message queue. That is to say, when the integrated message is saved in the internal message queue as a message to be sent, the integrated message that last enters the internal message queue is at the end of the internal message queue.

[0068] S340: Determine whether the integrated message exceeds the preset sending time. When it is determined that the integrated message does not exceed the preset sending time, execute step S350; when it is determined that the integrated message exceeds the preset sending time, end the process.

[0069] Specifically, the duration of the preset sending time can be set according to actual needs, and this embodiment does not specifically limit the duration of the preset sending time. It is understandable that when judging whether a certain integrated message exceeds the preset sending time, the time when the integrated message first enters the internal message queue is recorded as the start time, and the time when the integrated message needs to be sent from the internal message queue is recorded as the end time, and it is judged whether the duration between the start time and the end time exceeds the duration of the preset sending time.

[0070] S350: Determine whether the edge device meets the message receiving condition. When it is determined that the edge device meets the message receiving condition, execute step S360; when it is determined that the edge device does not meet the message receiving condition, return to step S330.

[0071] Specifically, in this embodiment, the determination of whether the edge device meets the message receiving condition can be to determine whether there are unprocessed messages on the edge device. The edge device can process one message at a time, so before sending the integrated message to the edge device, it is necessary to determine whether there are unprocessed messages on the edge device. It is worth mentioning that the determination of whether there are unprocessed messages on the edge device refers not only to integrated messages, but also to other instruction messages other than integrated messages.

[0072] S360: Send the integrated message to the edge device through the second information transmission channel.

[0073] S370: In response to the image file download request sent by the edge device according to the integrated message, the image file matching the image file download request is sent to the edge device through the first information transmission channel.

[0074] Compared with the related art, the embodiments of the present invention have at least the following advantages: by converting the model file into a mirror file, the mirror file is transmitted through the first information transmission channel, and the integrated message is transmitted through the second information transmission channel, so that the transmission of messages and files has a dedicated channel, and the decoupling design of message and file information transmission is realized, ensuring that the message can maintain a high throughput, thereby improving the efficiency of information transmission; files and messages are transmitted in the form of data streams, so that there is no blockage and delay in the communication between the cloud server and each device, and the business response speed is fast and the performance is high; in addition, the mirror file is transmitted to the mirror service, that is, the model is mirrored and served, so that the model after the mirror service has low coupling and small disk space, which improves the superiority of the method for issuing model files.

[0075] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.

[0077] The model conversion module 1 is used to convert the received model file into an image file and transmit the image file to the image service 4; the second transmission module 3 is used to transmit an integrated message to the edge device after receiving the model sending request, wherein the integrated message at least includes the attribute information of the image service and the attribute information of the image file; the image service 4 is used to send the image file matching the image file download request to the edge device through the first transmission module 2 after receiving the image file download request sent by the edge device according to the integrated message.

[0078] Please see further Figure 4 The cloud server also includes a message middleware 5; the second transmission module 3 is specifically used to transmit the integrated information to the message middleware 5 after receiving the model issuance request triggered by the user; the message middleware 5 is used to send the integrated message to the edge device after receiving the integrated message.

[0079] The cloud server provided in the embodiment of the present invention can execute the method for sending the model file provided in any embodiment of the present invention, and has the functional modules and beneficial effects corresponding to the execution method.

[0080] Embodiment 5

[0081] Figure 5This is a schematic diagram of the structure of a system for issuing a model file provided in Embodiment 5 of the present invention. The specific structure is as follows Figure 5 As shown, including:

[0082] A cloud server 100 and an edge device 20 having a mirror service 10; the cloud server 100 is used to convert a received model file into a mirror file and store the mirror file in the mirror service 10; the cloud server 100 is also used to respond to a model sending request and transmit an integrated message to the edge device 20 through a second information transmission channel, wherein the integrated message at least includes attribute information of the mirror service 10 and attribute information of the mirror file; the edge device 20 is used to send a mirror file download request to the mirror service 10 according to the integrated message; the mirror service 10 is used to send the mirror file corresponding to the mirror file download request to the edge device 20 through a first information transmission channel, wherein the first information transmission channel and the second information transmission channel are different channels.

[0083] It is worth mentioning that the cloud server 100 also includes a message middleware 30; after receiving the model issuance request triggered by the user, the cloud server 100 transmits the integrated information to the message middleware 30; the message middleware 30 is used to send the integrated message to the edge device 20 after receiving the integrated message; the message middleware 30 is also used to send the reply message of the edge device 20 to the cloud server 100.

[0084] The model file distribution system also includes an end device 40; the edge device 20 is also used to collect data from the end device 40, run the image file, input the data from the end device 40 into the image file, and distribute control instructions to the end device 40 according to the output result of the image file; the edge device 20 is also used to send a reply message to the cloud server 100; the cloud server 100 is also used to continue to send the remaining messages to be distributed after receiving the reply message; the end device 40 is used to perform operations according to the control instructions.

[0085] For ease of understanding, the following takes the MQTT middleware as an example. Figure 6 The message processing method of the edge device 20 is specifically described:

[0086] After receiving the integrated message, the edge device 20 processes the integrated message asynchronously. On the one hand, the reply message is sent to the cloud server 100 through the message middleware 30. After receiving the message, the cloud server 100 will send other messages to be sent later. On the other hand, the integrated message is processed, and after decompressing and decrypting the integrated message, the address, user name, password and image name of the image service 10 to be downloaded are obtained. Through this information, the image service 10 is connected to obtain the returned image file. The edge device 20 runs the image file locally, analyzes the collected end data, and sends corresponding control instructions to the end device 40 according to the analysis results. In this way, the local data analysis service of the edge device 20 is not affected when the public network is interrupted.

[0087] It is worth mentioning that by first sending the relevant address of the image service 10 to the edge device 20, and then the edge device 20 downloads the image file according to the address, the parallelism of the model delivery is increased. In addition, after receiving the integration message, the cloud server is immediately replied to indicate that the integration information has been received, and the cloud server can then send the next message, which effectively improves the message processing speed.

[0088] The system for sending model files provided in the embodiment of the present invention can execute the method for sending model files provided in any embodiment of the present invention, and has the corresponding functional modules and beneficial effects of the execution method.

[0089] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
