In order to make the purpose, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.

For the sake of brevity and intuition in description, the solution of the present invention is described below by describing several representative implementation manners. Numerous details in the embodiments are only used to help the understanding of the solutions of the present invention. But obviously, the technical solutions of the present invention may not be limited to these details when implemented. In order to avoid unnecessarily obscuring the solution of the present invention, some embodiments are not described in detail, but only a framework is given. Hereinafter, "including" means "including but not limited to", and "according to..." means "at least according to, but not limited to only based on...". Due to the language habits of Chinese, when the quantity of a component is not specifically indicated below, it means that the component can be one or more, or can be understood as at least one.

Fig. 1 is a flowchart of a method for deploying industrial edge applications according to an embodiment of the present invention. The method 100 can be executed by a central node connected to multiple industrial edge devices.

As shown in Figure 1, the method 100 includes:

Step 101: Obtain a first label of each industrial edge device, where the first label describes the capability of each industrial edge device.

Here, industrial edge devices can include smart devices on the industrial site, such as transmitters, programmable logic controllers (PLCs), and programmable automation controllers (PACs), as well as devices that connect various network components or bridge different networks. Edge gateways such as protocol converters, routers and industrial PCs, etc.

The central node may receive the first registration request of each industrial edge device from the industrial edge device. Each first registration request includes a first label of the industrial edge device sending the first registration request, wherein the first label describes the capability of the industrial edge device.

In one embodiment, the first label is determined by each industrial edge device based on a capability self-check process, or the first label is determined by each industrial edge device querying a capability parameter table stored in a third-party database.

For example, the central node is connected to five industrial edge devices, which are industrial edge device 1, industrial edge device 2, industrial edge device 3, industrial edge device 4, and industrial edge device 5. The industrial edge device 1 , the industrial edge device 2 , the industrial edge device 3 , the industrial edge device 4 and the industrial edge device 5 respectively send respective first registration requests to the central node. Wherein: the first registration request sent by the industrial edge device 1 contains the first label describing the capability of the industrial edge device 1; the first registration request sent by the industrial edge device 2 contains the first label describing the capability of the industrial edge device 2; The first registration request sent by the industrial edge device 3 contains the first label describing the capability of the industrial edge device 3; the first registration request sent by the industrial edge device 4 contains the first label describing the capability of the industrial edge device 4; the industrial edge The first registration request sent by the device 5 includes a first label describing the capabilities of the industrial edge device 5 .

In an embodiment, the capability of the industrial edge device includes: hardware capability of the industrial edge device; software capability of the industrial edge device; firmware capability of the industrial edge device; operating system capability of the industrial edge device, and so on. For example, the capabilities of industrial edge devices can include: capabilities about CPUs (such as the number of cores, frequency, RISC, etc.), capabilities about RAM (such as capacity or ECC), capabilities about network cards (such as speed), Capabilities on real-time operating systems (e.g., CPU core isolation or Linux rt-patch), capabilities on real-time networks (e.g., TSN), capabilities on industrial fieldbuses/protocols (e.g., PROFINET or OPC UA, etc.) or About high availability capabilities (such as UPS), and so on.

The above exemplarily describes a typical example of the ability to obtain the first tag and the industrial edge device, and those skilled in the art can realize that this description is only exemplary, and is not intended to limit the protection scope of the embodiments of the present invention.

Step 102: Obtain a second label of each component module in the industrial edge application to be deployed, where the second label describes the deployment requirement of each component module.

Here, the industrial edge application to be deployed is divided into multiple constituent modules. Among them, the industrial edge application to be deployed can be divided into multiple component modules based on various module division methods such as functional division, hierarchical division, professional division, and demand division. For example, the constituent modules can be specifically implemented as microservices. Each component service in the microservice architecture can be developed, deployed, operated, and expanded without affecting the functionality of other services. These services do not need to share any code or implementation with other services. Communication between the various components is done through well-defined APIs.

Moreover, the central node may obtain the second label of each component module from sources such as the provider of the industrial edge application, where each second label describes the deployment requirement of the corresponding component module. Considering that there is usually a need for mutual communication between the various components that constitute the industrial edge application, the requirements for the communication protocol between the components can be further described in the second label, such as HTTP-based RESTful, Remote Procedure Call (Remote Procedure Call, RPC) or communication services based on Message Queuing Telemetry Transport (MQTT), etc. In fact, industrial edge devices usually have the ability to support communication protocols between constituent modules.

For example, the industrial edge application is divided into four components, namely component module 1, component module 2, component module 3 and component module 4. The provider of the industrial edge application (for example, the developer) sends (for example, through the interactive interface of the central node) the first component of each component module in the component module 1, component module 2, component module 3 and component module 4 Two tabs. The second label of each component module describes the capability requirement of the corresponding component module for the industrial edge device to be deployed. Among them: the second label of component module 1 describes the capabilities required to deploy the industrial edge equipment of component module 1; the second label of component module 2 describes the capabilities required for the deployment of component module 2; the second label of component module 3 The label describes the capabilities required for the deployment of the industrial edge device of the component module 3; the second label of the component module 4 describes the capabilities required for the deployment of the industrial edge device of the component module 4.

The deployment requirements may include: requirements for hardware capabilities of industrial edge devices; requirements for software capabilities of industrial edge devices; requirements for firmware capabilities of industrial edge devices; requirements for operating system capabilities of industrial edge devices, and so on. For example, the capabilities of industrial edge devices can include: capabilities about CPUs (such as the number of cores, frequency, RISC, etc.), capabilities about RAM (such as capacity or ECC), capabilities about network cards (such as speed), Capabilities on real-time operating systems (e.g., CPU core isolation or Linux rt-patch), capabilities on real-time networks (e.g., TSN), capabilities on industrial fieldbuses/protocols (e.g., PROFINET or OPC UA, etc.) or About high availability capabilities (such as UPS), and so on.

Step 103: Based on the relationship between the capability described by the first label and the deployment requirement described by the second label, determine the industrial edge device to deploy each component module.

For example, the central node determines the industrial edge device where each component module is deployed based on the matching process of the first label and the second label. Wherein, when the capabilities described in the first label fully meet the deployment requirements described in the second label, it is determined that the first label has a matching relationship with the second label, and at this time the industrial edge device that provides the first label can deploy the The constituent modules of the second label. Otherwise, when the capabilities described in the first label cannot fully cover the deployment requirements described in the second label, it is determined that the first label does not have a matching relationship with the second label, and the industrial edge device that provides the first label does not The constituent modules of the second label can be deployed.

In one embodiment, when the number of industrial edge devices (referred to as candidate industrial edge devices) that can deploy the constituent modules of the second label is multiple, these multiple industrial edge devices can be formed into a candidate industrial edge device list, That is, the first tab contains a list of industrial edge devices that make up the second tab of the module. Then, based on a predetermined criterion, the industrial edge device on which the component module is deployed is determined from the list of candidate industrial edge devices. For example, determine whether the capability of the industrial edge device described by each first label meets the deployment requirements of a component module, and if so, determine the industrial edge device as a candidate industrial edge device suitable for deploying the component module; if No, the industrial edge device is not determined as a candidate industrial edge device; a candidate industrial edge device list including all candidate industrial edge devices is generated; and an industrial edge device to deploy the component module is determined from the candidate industrial edge device list.

The industrial edge device on which the component module is deployed can be determined from the candidate industrial edge device list based on the specific requirements of the component module. For example, the industrial edge device with the smallest load may be determined from the list of industrial edge devices; the industrial edge device with the smallest load is determined as the industrial edge device where the constituent modules are deployed. It can be seen that by taking the industrial edge device with the smallest load as the deployment location of the component modules, sufficient available resources of the component modules are guaranteed. For another example, the industrial edge device with the least load may be determined from the list of industrial edge devices; the industrial edge device with the fastest network speed is determined as the industrial edge device where the component modules are deployed. It can be seen that by using the industrial edge device with the fastest network speed as the deployment location of the component modules, it is ensured that the component modules have sufficient network transmission speed.

Similarly, the above process can be repeated for each component module, and finally the industrial edge device to be deployed is determined for each component module.

Example: Assume that the central node is connected to 5 industrial edge devices, namely industrial edge device 1, industrial edge device 2, industrial edge device 3, industrial edge device 4, and industrial edge device 5. The industrial edge application is divided into three building blocks, namely building block 1, building block 2 and building block 3.

For component module 1: judge whether the first label of each industrial edge device in industrial edge device 1, industrial edge device 2, industrial edge device 3, industrial edge device 4, and industrial edge device 5 satisfies the second label of component module 1 Deployment requirements described in the tags. Assuming that industrial edge device 1, industrial edge device 2, and industrial edge device 3 meet the requirements, then the list of candidate industrial edge devices that make up module 1 is determined to be: industrial edge device 1, industrial edge device 2, and industrial edge device 3. Considering that component module 1 needs to occupy a large amount of computing resources, the device with the smallest load in the candidate industrial edge device list of component module 1 is finally determined as the industrial edge device where component module 1 is deployed.

For component module 2: judge whether the first label of each industrial edge device in industrial edge device 1, industrial edge device 2, industrial edge device 3, industrial edge device 4, and industrial edge device 5 satisfies the second label of component module 2 Deployment requirements described in the tags. Assuming that industrial edge device 1, industrial edge device 2, and industrial edge device 4 meet the requirements, then the list of candidate industrial edge devices that make up module 2 is determined to be: industrial edge device 1, industrial edge device 2, and industrial edge device 4. Considering that component module 2 has a high demand for network speed, the device with the fastest network speed in the candidate industrial edge device list of component module 2 is finally determined as the industrial edge device where component module 2 is deployed.

For component module 3: determine whether the first label of each industrial edge device in industrial edge device 1, industrial edge device 2, industrial edge device 3, industrial edge device 4, and industrial edge device 5 satisfies the second label of component module 3 Deployment requirements described in the tags. Assuming that the industrial edge device 2 and the industrial edge device 4 meet the requirements, then the list of candidate industrial edge devices that make up the module 3 is determined as: the industrial edge device 2 and the industrial edge device 4 . Considering that the component module 3 needs to occupy a large amount of computing resources, the device with the smallest load in the candidate industrial edge device list of the component module 3 is finally determined as the industrial edge device where the component module 3 is deployed.

In one embodiment, the method further includes: receiving a second registration request from the industrial edge device deploying the component module, wherein the second registration request contains a third label describing the capability of the component module; combining the third label and the access component module The interface address of the module is delivered to other industrial edge devices except the industrial edge device where the component is deployed, so that when other industrial edge devices need to obtain the capability of the component module, they can access the component module based on the interface address. Here, the capability of the constituent module includes the functions that the constituent module can realize. For example, when the component module is implemented as an artificial intelligence module, the capability is the artificial intelligence function; when the component module is implemented as a fault detection module, the capability is the fault detection function, and so on.

It can be seen that the capability of a component module can also be used as the capability of the industrial edge device deploying the component module, so that other industrial edge devices can access the component module to obtain the capability of the component module. Therefore, the capabilities of the constituent modules deployed in an industrial edge device can be further provided to other industrial edge devices.

Based on the matching process of all the first tags and all the second tags, the central node 30 determines that: the deployment device of the first component module 41 is the first edge device 31, and the deployment device of the second component module 42 is the second edge device 32. The deployment device of the third component module 43 is the third edge device 33 .

(For example, when the first component module 41 is an artificial intelligence module, the third label describes that the first component module 41 has artificial intelligence capabilities). The central node 30 sends the third label and the interface address of the access first component module 41 to the second edge device 32 and the third edge device 33, so that when the second edge device 32 or the third edge device 33 needs to obtain the first component When the capability of the module 41 is determined, the first component module 41 may be accessed based on the interface address, and the capability of the first component module 41 may be acquired. Similarly, the second edge device 32 may send the third label describing the capability of the second component module 42 through the central node 30, and the third edge device 33 may transmit the third label describing the capability of the third component module 43 through the central node 30, thereby The capability of the second component module 42 and the capability of the third component module 43 are shared across edge devices.
