[0026] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0027] The present application provides a cloud-edge collaborative message intercommunication system for the Internet of Things, which includes a cloud and an edge. It is understood that the cloud refers to the cloud server and the edge refers to the edge server. The present application aims to open up a channel for message intercommunication under cloud-edge collaboration, and realize message intercommunication between the cloud and the edge under cloud-edge collaboration. Cloud-edge collaboration refers to the complementary collaboration between cloud computing and edge computing. Cloud computing can grasp the overall situation, process large amounts of data and conduct in-depth analysis, and plays an important role in non-real-time data processing scenarios, while edge computing focuses on the local area and can better play a role in small-scale, real-time intelligent analysis to meet the real-time needs of local data processing. The present application also provides a cloud-edge collaborative message intercommunication method for the Internet of Things applied to the above-mentioned system. Based on the cloud-edge collaborative message intercommunication method for the Internet of Things, the message intercommunication channel under cloud-edge collaboration can be realized without intrusion into the existing cloud-edge collaborative architecture, without adjusting the business code, and without perception of development. It can maintain the existing development methods and processes, and can achieve code consistency on both ends of the cloud and edge, avoiding the need to maintain different branch codes, thereby reducing the complexity of maintenance.

[0028] In some embodiments of this application, please refer to Figure 1 , Figure 1This is the implementation flowchart of the first cloud-edge collaborative message intercommunication method provided by the embodiments of this application. This cloud-edge collaborative message intercommunication method of the Internet of Things is applied to the cloud. Exemplarily, as Figure 1 shown, the above method may specifically include the following steps:

[0029] S11: The cloud producer obtains the first message to be consumed, and delivers the first message to be consumed to the cloud public queue for waiting to be consumed;

[0030] S12: The cloud virtual consumer subscribes to messages from the cloud public queue, obtains the first message to be consumed, and delivers the first message to be consumed to the cloud private queue for waiting to be consumed, where the cloud private queue accepts the subscription of the edge consumption proxy service.

[0031] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the process of sending a message from the cloud to the edge for consumption provided by the embodiments of this application. As Figure 2 shown, the cloud is configured with a cloud producer, a cloud public queue, a cloud virtual consumer, a cloud private queue, and a message interceptor.

[0032] During the process of the cloud creating a message and sending it to the edge for consumption, in the cloud, the cloud producer can obtain the first message to be consumed from the business system accessed by the cloud. After the cloud producer obtains the first message to be consumed, the obtained first message to be consumed can be delivered to the cloud public queue by the cloud producer for waiting to be consumed. In this embodiment, the cloud public queue can cache the first messages to be consumed from different business systems. It should be noted that the first message to be consumed is the data to be processed uploaded by the business system to the cloud, and the cloud can access one or more business systems.

[0033] The cloud virtual consumer is used to simulate an edge consumer to consume the first message to be consumed obtained by the cloud producer. In this embodiment, a subscription link can be established between the cloud virtual consumer and the cloud public queue, so that the cloud virtual consumer can subscribe to messages from the cloud public queue through the subscription link, thereby obtaining the first message to be consumed through the subscription message. After the cloud virtual consumer obtains the first message to be consumed, the cloud virtual consumer can deliver the obtained first message to be consumed to the cloud private queue for consumption. In the cloud, the cloud private queue can accept subscriptions from the edge consumption proxy service, thereby effectively opening up the channel for message exchange under cloud-edge collaboration and communicating messages between the cloud and the edge. In this embodiment, the cloud private queue can establish a mapping association with the business system, so that the cloud private queue corresponds to the business system one-to-one. It is understandable that multiple cloud private queues can be created in the cloud to connect to different business systems and provide them to the edge for use, so as to avoid mutual impact between cloud and edge businesses.

[0034] In some embodiments of this application, please refer to Figure 3 , Figure 3 The second embodiment of the present application provides a flowchart for implementing the cloud-edge collaborative message intercommunication method of the Internet of Things. The cloud-edge collaborative message intercommunication method of the Internet of Things is applied at the edge. For example, Figure 3 As shown, the above method may specifically include the following steps:

[0035] S31: The edge consumption proxy service subscribes to messages from the cloud private queue to obtain the first message to be consumed;

[0036] S32: The edge consumption proxy service simulates the cloud producer and delivers the first message to be consumed to the edge public queue for consumption;

[0037] S33: The edge consumer subscribes to messages from the edge public queue, obtains the first message to be consumed, and processes the first message to be consumed.

[0038] In this embodiment, Figure 2 As shown, the edge is configured with edge consumption proxy service, edge public queue and edge consumer.

[0039] Based on the fact that the cloud - side private queue can accept subscriptions from the edge - side consumption proxy service. At the edge - side, by establishing a subscription link between the edge - side consumption proxy service and the cloud - side private queue, the edge - side consumption proxy service can subscribe to messages from the cloud - side private queue, thereby realizing the transfer of the first message to be consumed from the cloud to the edge - side. After the edge - side consumption proxy service obtains the first message to be consumed, it can simulate the cloud - side producer through the edge - side consumption proxy service and deliver the first message to be consumed into the edge - side public queue for waiting to be consumed. In this embodiment, the edge - side public queue can also cache the first messages to be consumed from different business systems. Among them, at the edge - side, the first messages to be consumed of different business systems are delivered to the edge - side public queue through different edge - side consumption proxy services. At the edge - side, the edge - side public queue can accept subscriptions from edge - side consumers, that is, at the edge - side, by establishing a subscription link between the edge - side public queue and the edge - side consumers, the edge - side consumers can subscribe to messages from the edge - side public queue, thereby realizing that the edge - side consumers can obtain the first message to be consumed from the edge - side public queue, and then process the first message to be consumed through the edge - side consumers. In this way, the process of message inter - communication between the cloud and the edge - side under cloud - edge collaboration is realized.

[0040] As can be seen from the above, in the cloud - edge collaborative message inter - communication method of the Internet of Things provided by the embodiments of the present application, the first message to be consumed is obtained through the cloud - side producer and delivered to the cloud - side public queue for waiting to be consumed. The cloud - side virtual consumer subscribes to messages from the cloud - side public queue and delivers the first message to be consumed to the cloud - side private queue for waiting to be consumed. The edge - side consumption proxy service subscribes to messages from the cloud - side private queue and obtains the first message to be consumed. The edge - side consumption proxy service simulates the cloud - side producer and delivers the first message to be consumed to the edge - side public queue for waiting to be consumed. The edge - side consumer subscribes to messages from the edge - side public queue, obtains the first message to be consumed and processes the first message to be consumed. In this way, through the cloud - side virtual consumer in the cloud and the edge - side consumption proxy service in the edge - side, the channel for message inter - communication under cloud - edge collaboration can be effectively opened up, and the technical problem of how messages are inter - communicated between the cloud and the edge - side under cloud - edge collaboration is solved.

[0041] In some embodiments of the present application, please refer to Figure 4 , Figure 4 is a flowchart of a method when the cloud - side virtual consumer delivers the first message to be consumed to the cloud - side private queue in the first cloud - edge collaborative message inter - communication method provided by the embodiments of the present application. Exemplarily, as Figure 4 shown, the above - mentioned method may specifically include the following steps:

[0042] S41: Use a preset message interceptor to judge whether the first message to be consumed meets the preset interception condition;

[0043] S42: If not satisfied, deliver the first message to be consumed to the cloud private queue for waiting to be consumed.

[0044] In this embodiment, based on the one-to-one correspondence between the cloud private queue and the business system, a message interceptor can be configured between the cloud virtual consumer and the cloud private queue. The first message to be consumed written into the cloud private queue is determined through the message interceptor, so as to effectively ensure the security of the process of sending messages from the cloud to the edge for consumption. Specifically, an interception condition can be set in the message interceptor. Exemplarily, the interception condition can be set as the read / write permission of the private queue. For example, in the cloud, the interception condition of the cloud private queue A is the first message to be consumed generated by other business systems except the business system A'. That is, the message interceptor only delivers the first message to be consumed generated by the business system A' to the cloud private queue A. In this embodiment, when the cloud virtual consumer delivers the first message to be consumed to the cloud private queue, the cloud virtual consumer can transmit the first message to be consumed obtained by subscribing from the cloud public queue to the message interceptor for identification. The message interceptor determines whether the first message to be consumed meets the interception condition. If the interception condition is not met, it means that the cloud private queue has the write permission for the first message to be consumed. At this time, the first message to be consumed can be delivered to the cloud private queue for waiting to be consumed.

[0045] In some embodiments of the present application, please refer to Figure 5 , Figure 5 which is another implementation flowchart of the first cloud-edge collaborative message intercommunication method provided by the embodiments of the present application. This cloud-edge collaborative message intercommunication method is applied to the cloud. Exemplarily, as Figure 5 shown, the above method may specifically include the following steps:

[0046] S51: The cloud virtual producer receives the second message to be consumed reported by the edge consumption proxy service, and simulates the edge producer to deliver the second message to be consumed to the cloud public queue for waiting to be consumed;

[0047] S52: The cloud consumer subscribes to messages from the cloud public queue, obtains the second message to be consumed and processes the second message to be consumed.

[0048] Please also refer to Figure 6 , Figure 6 which is a schematic diagram of the process of sending messages from the edge to the cloud for consumption provided by the embodiments of the present application. As Figure 6 shown, a cloud consumer and a cloud virtual producer are also configured in the cloud.

[0049] During the process of the edge - end creation message sending the message to the cloud for consumption, in the cloud, a communication connection can be established between the cloud virtual producer and the edge - end consumption proxy service of the edge - end. The cloud virtual producer receives the second message to be consumed reported by the edge - end consumption proxy service. After the cloud virtual producer receives the second message to be consumed, in the cloud, the cloud virtual producer can simulate the edge - end producer to deliver the second message to be consumed into the cloud public queue for waiting to be consumed. And the cloud consumer in the cloud can obtain the second message to be consumed transmitted from the edge - end by subscribing to the message from the cloud public queue, so as to enable the cloud consumer to process the second message to be consumed transmitted from the edge - end. In some specific embodiments of the present application, the communication connection between the cloud virtual producer and the edge - end consumption proxy service of the edge - end can be established through the RPC remote call service. Among them, RPC (Remote Procedure Call Protocol) refers to the remote procedure call protocol, which is a protocol for requesting services from remote computer programs through the network without the need to understand the underlying network technology. In this embodiment, RPC uses the https protocol and uses the authentication mechanism of openapi (open interface) to ensure the security of communication.

[0050] In some embodiments of the present application, please refer to Figure 7 , Figure 7 which is a flowchart of a method for the edge - end consumption proxy service to establish a subscription link with the cloud private queue in the second cloud - edge collaborative message intercommunication method provided by the embodiment of the present application. Exemplarily, as Figure 7 shown, the above - mentioned method may specifically include the following steps:

[0051] S71: Identify whether the edge - end consumption proxy service has read permission in the cloud private queue;

[0052] S72: If it has, establish a subscription link between the edge - end consumption proxy service and the cloud private queue, where the subscription link is used to transfer the first message to be consumed from the cloud private queue to the edge - end consumption proxy service.

[0053] In this embodiment, at the edge side, before establishing a subscription link between the edge-side consumption proxy service and the cloud private queue, the security of the connection between the edge-side consumption proxy service and the cloud private queue can be ensured by identifying whether the edge-side consumption proxy service has read permission in the cloud private queue. Specifically, the edge-side read permission can be set in the cloud private queue. For example, the identity identifier of the edge-side consumption proxy service that can be connected to the cloud private queue is stored in the cloud private queue. Before establishing a subscription link between the edge-side consumption proxy service and the cloud private queue, the identity identifier of the edge-side consumption proxy service is compared with the identity identifier stored in the cloud private queue to determine whether the two identity identifiers are the same. If they are the same, it is recognized that the edge-side consumption proxy service has read permission in the cloud private queue; otherwise, it does not have read permission. When the edge-side consumption proxy service has read permission in the cloud private queue, the edge-side consumption proxy service is triggered to connect to the cloud private queue to establish a subscription link between the edge-side consumption proxy service and the cloud private queue. In this embodiment, this subscription link is used to transfer the first message to be consumed from the cloud private queue to the edge-side consumption proxy service, thereby effectively opening up the message intercommunication channel under cloud-edge collaboration and realizing message intercommunication between the cloud and the edge side.

[0054] In some embodiments of the present application, please refer to Figure 8 , Figure 8 which is another implementation flowchart of the second cloud-edge collaboration message intercommunication method for the Internet of Things provided by the embodiments of the present application. This cloud-edge collaboration message intercommunication method for the Internet of Things is applied to the edge side. Exemplarily, as Figure 8 shown, the above method may specifically include the following steps:

[0055] S81: The edge-side producer obtains the second message to be consumed and delivers the second message to be consumed to the edge-side public queue for waiting to be consumed;

[0056] S82: The edge-side consumption proxy service subscribes to messages from the edge-side public queue, obtains the second message to be consumed, and reports the second message to be consumed to the cloud virtual producer, where the cloud virtual producer is used to simulate the edge-side producer to deliver the second message to be consumed to the cloud public queue for waiting to be consumed.

[0057] In this embodiment, please refer to Figure 6, an edge producer is also configured at the edge side. In this embodiment, at the edge side, the edge producer can obtain the second message to be consumed from the service system accessed at the edge side. After the edge producer obtains the second message to be consumed, the obtained second message to be consumed can be delivered to the edge public queue by the edge producer for waiting to be consumed. It should be noted that the second message to be consumed is the data to be processed uploaded by the service system to the edge side, and one or more service systems can be accessed at the edge side. After the edge producer delivers the second message to be consumed to the edge public queue, the edge consumption proxy service can subscribe to messages from the edge public queue to obtain the second message to be consumed. Furthermore, based on the communication connection between the edge consumption proxy service and the cloud virtual producer, the edge consumption proxy service reports the second message to be consumed to the cloud virtual producer, so as to effectively open up the message intercommunication channel under cloud-edge collaboration and perform message intercommunication between the cloud and the edge side. In this embodiment, the cloud virtual producer is used to simulate the edge producer delivering the second message to be consumed to the cloud public queue for waiting to be consumed. In some specific implementation manners of the present application, the cloud virtual producer and the edge consumption proxy service at the edge side can be communicatively connected through an RPC remote call service, so that the edge consumption proxy service can use the RPC remote call service to report the second message to be consumed to the cloud virtual producer.
