[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0033] 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.

[0034] The embodiment of the present invention provides an industrial data access and forwarding system, which is connected to industrial equipment; Figure 1 As shown, the industrial data access and forwarding system includes: a core framework layer 11, an extension layer 12 and an external function plug-in layer 13.

[0035] The extension layer 12 is connected and communicated with the core framework layer 11 and the external function plug-in layer 13 respectively.

[0036] Furthermore, the core framework layer 11 includes a console 111, an adapter library 112 and a basic library 113; the extension layer 12 includes a control panel 121, a command line tool 122, a plug-in library 123, a data persistence plug-in 124 and an SDK interface 125; the external function plug-in layer 13 includes: a message agent 131, a database 132, a message flow 133, a message queue 134 and other applications 135.

[0037] Among them, the plug-in library 123 may include protocol plug-ins, MQTT plug-ins, other service plug-ins, etc. Each plug-in can be developed according to the data persistence plug-in and SDK interface; the adapter library 112 may include protocol driver adapters, MQTT adapters and other adapters, etc.

[0038] Furthermore, the interaction between the core framework layer 11, the extension layer 12 and the external function plug-in layer 13 is described. Through the interaction between these three layers, the access and forwarding of industrial data can be achieved.

[0039] Specifically, the control panel 121 or the command line tool 122 in the extension layer 12 receives a data acquisition instruction, and under the control of the data acquisition instruction, calls the first plug-in in the plug-in library 123, and further sends the data acquisition instruction and the plug-in data of the called first plug-in to the console 111 in the core framework layer 11; wherein the first plug-in can be any plug-in in the plug-in library 123, determined according to the data acquisition instruction.

[0040] After receiving the plug-in data of the first plug-in, the console 111 calls the first adapter matching the plug-in data in the adapter library 112, and binds the plug-in data with the first adapter to obtain a first data node. Further, the first data node is a functional node that can configure the IP, protocol parameters, transmission mode (active, passive), etc. of the data acquisition device. The first adapter can be any adapter library in the adapter library 112, determined according to the plug-in data.

[0041] Further, under the control of the data acquisition instruction, the console 111 controls the first data node to acquire the first device data sent by the industrial device 2 connected to the industrial data access and forwarding system.

[0042] The first data node uses the first adapter as a carrier of the first plug-in and controls the plug-in to obtain data.

[0043] Specifically, during the communication process, the first adapter sends a command to obtain data to the first plug-in. After receiving the command, the first plug-in communicates with the industrial device 2 and returns the communication data, that is, the first device data, through the callback function interface.

[0044] Further, after obtaining the first device data, the console 111 uses a specific protocol conversion program to convert the first device data of different protocol types into a unified data format, namely, second device data. Then, the console 111 forwards the second device data to the external function plug-in layer 13.

[0045] First, the console 111 calls the second adapter in the adapter library 112 according to the second device data, and sends the adapter data of the second adapter and the second device data together to the control panel 121 .

[0046] After receiving the adapter data, the control panel 121 calls the second plug-in matching the adapter data in the plug-in library 123, and binds the adapter data with the second plug-in to obtain a second data node. Further, the second data node is a functional node that forwards the second device data.

[0047] Through the above embodiments, any data node in the system can be dynamically created or destroyed without interfering with other running nodes, that is, the industrial data access and forwarding system can very flexibly start a new node service by loading a plug-in module at runtime, or uninstall the plug-in module of a stopped node service.

[0048] Furthermore, the industrial device 2 will actively send the first device data to the first data node. After receiving the first device data, the first data node will send the first device data to the console 111 for storage until a data acquisition instruction is received. The console 111 then forwards the first device data to the external function plug-in layer 13.

[0049] When the industrial device 2 sends a plurality of first device data to the first data node, each first device data is sent to the first data node in sequence according to a preset queue, such as Figure 2 As shown, the sequential processing of device data is guaranteed, achieving the purpose of loose coupling and fast message transmission.

[0050] Furthermore, in the above-mentioned interaction process between the core framework layer 11 and the extension layer 12, a connection needs to be made through a serial port. Therefore, a basic library 113 is provided in the core framework layer for storing the communication serial port.

[0051] Furthermore, in the above-mentioned interaction process, all nodes are centered around a star-shaped message bus, which adopts a broker-less mode. Generally, data may be lost in a broker-less mode. Therefore, in the embodiment of the present invention, the core framework layer communicates internally through an internal message bus. Therefore, a message bus is provided to store the processing status of each first device data received by the core framework layer. By adding a state storage to record the processing status of the message, it is ensured that a device data message is processed exactly once.

[0052] The industrial data access and forwarding system provided by the embodiment of the present invention can select different plug-ins to load into the corresponding adapter according to different data acquisition instructions during data access, forming different first data nodes for data acquisition; when forwarding data, it can also select different plug-ins to load into the corresponding adapter according to different received data, forming different second data nodes for data forwarding; at the same time, before forwarding the accessed data, the format of the accessed data will be converted so that it can adapt to different adapters and plug-ins, and complete the forwarding. Therefore, all data processing processes in the present invention are run in a loosely coupled thread environment, realizing a mechanism similar to hot-swappable devices, and the device can be connected to the entire system without shutting down. At the same time, any data node can be easily created or destroyed without affecting the normal operation of other nodes.

[0053] Based on the internal interaction process of the industrial data access and forwarding system provided by the above embodiment of the present invention, in one embodiment, a topology structure of a message bus mode is provided, such as Figure 3 As shown, the message bus mode is used for internal interaction of industrial data access and forwarding systems.

[0054] Specifically, the message bus is based on the pair-1 feature of the NNG library to organize a star-shaped scalable framework. There is a message router core in the center. There are two types of nodes around the router core. The southbound driver node is the node that communicates with the device, and it is a data producer. The northbound application node is a data consumer that processes or forwards data information. The communication between nodes relies on NNG's efficient asynchronous I / O to fully utilize the capabilities of multi-core CPUs.

[0055] Each node (southbound or northbound) consists of a plug-in adapter and a plug-in.

[0056] Specifically, all plugins (such as Figure 1Other services, MQTT Broker and protocol plug-ins in the MQTT broker are based on the Adapter as a carrier. Users can dynamically add plug-ins with different functions according to the functional requirements of the application scenario to obtain different nodes. Each node runs independently. When a node plug-in is upgraded, loaded or unloaded, it will not affect the normal operation of other nodes.

[0057] Further, in one example, based on Figure 3 The topology of the message bus mode shown in FIG. 1 provides an industrial protocol gateway system running on edge gateway hardware. The hierarchical structure of the system is as follows: Figure 4 shown.

[0058] Specifically, the lowest level design in the system is the basic message communication library based on NNG. The message transmission of each node must rely on this communication library, and it provides basic thread management, dynamic library management, and various basic function functions. It also includes various types of adapters, such as streaming computing, MQTT connection, and driver connection. The middle layer is various functional plug-ins, and each plug-in provides different services through the loading of adapters, such as drivers, MQTT conversion, etc. The top layer is third-party applications that run independently and provide application services, such as edge streaming computing frameworks, MQTT-brokers, etc. The basic message communication library based on NNG solves the problem of repeated messages, and can fully utilize multiple cores of the CPU.

[0059] The data transmission and conversion process of this system is as follows Figure 5 As shown, the user dynamically loads the required application or function plug-in into the adapter (generally in the form of a Linux dynamic library .so file) according to the on-site working conditions. After loading, the plug-in initialization and configuration process is executed. The service node will issue a device data reading command and execute the plug-in function (request) according to the reading frequency set by the data tag. After receiving the data reply, it will execute the callback function (response). Through a specific protocol conversion program, data of different protocol types are converted into a unified data format to facilitate internal data processing. The system forwards the received data to the consumer end through the message bus according to the needs of the data consumer end, such as the MQTT agent, edge streaming computing framework, etc.

[0060] Therefore, in general, users only need to implement the required services in different plug-ins independently, isolating the coupling of functions between nodes. At the same time, the system supports third-party proxy plug-ins (such as remote calls), and can realize data exchange according to the communication interface API of the third-party proxy plug-in, and load it into the adapter to realize the connection with third-party software.

[0061] Furthermore, the edge streaming computing process is as follows Figure 6 As shown, the edge streaming computing module is integrated into the system in plug-in mode. The data is converted into JSON format through the NNG message bus for data exchange and consumed by the edge computing module. Real-time status analysis and calculation are performed on the infinite data stream. SQL is used for data processing, and built-in functions are used to quickly process structured and unstructured data, thereby directly processing the data sources of different industrial equipment and forwarding the processing results to other consumers or importing them into local storage.

[0062] Specifically, since streaming data is infinite, it is impossible to process it as a whole. Therefore, a window method is used to process streaming data. The window divides the unbounded data into a series of continuous bounded data for calculation. Here, windows are divided into two types: time windows: windows divided by time. Count windows: windows divided by element count. Among them, the commonly used time windows are divided into rolling windows (0-5s, 5-10s), jumping windows (0-5s, 2-10s), sliding windows, session windows, etc. These windows are called in the edge streaming computing framework in the form of built-in functions, so that the unbounded data is cut into limited data sets for analysis and calculation. Based on the limited data sets, conventional SQL functions can be called for calculation or custom algorithms can be implemented in the framework with code. The data in the continuous window is continuously calculated to obtain continuously updated calculation results.

[0063] The embodiment of the present invention further provides an industrial data access and forwarding method, which is used in the industrial data access and forwarding system as described in the embodiment of the present invention, wherein the system is connected to the industrial equipment; Figure 7 As shown, the method comprises the following steps:

[0064] Step 101: The control panel in the industrial data access and forwarding system receives a data acquisition instruction, and based on the data acquisition instruction, calls a first plug-in in the plug-in library, and sends the data acquisition instruction and the plug-in data of the first plug-in to the control console in the industrial data access and forwarding system.

[0074] Specifically, the industrial equipment will actively send the first device data to the first data node. After receiving the first device data, the first data node will send the first device data to the console for storage until it receives a data acquisition instruction, and then the console will forward the first device data to the external function plug-in layer.
