As shown in fig. 3, the control method of the industrial system includes steps S101 to S104.

S101, when detecting that the state of the working equipment of the equipment cluster changes, the development board acquires equipment information and state information of the working equipment.

Wherein the device cluster may include a plurality of working devices such as field devices, base network devices, industrial control devices, and the like. The change in the state of the working device may indicate a change in the state of the working device, a change in the information of the working device, or the like. For example, when the working device is turned on or turned off, the working device is controlled to perform operations such as collecting data, and the state of the working device can be considered to be changed.

In some embodiments, the development board detects the status of each working device in the device cluster through a listener; the development board controls each working device in the device cluster to acquire data, so that the working device updates the state information when acquiring working data; and after the development board detects the state information to update, acquiring the equipment information and the state information of the working equipment. Therefore, the state of each working device can be accurately monitored through the monitoring program, and when the state information is updated, the device information and the state information corresponding to the working device are acquired.

Wherein the listener may be configured to listen for a change in state of the working device, and upon the change in state of the working device, may send a message to notify the development board.

Specifically, a listener may be installed on the development board to monitor the status of each working device in the device cluster. At the moment, each working device in the development board control device cluster performs data acquisition, so that when the working device acquires working data, the working device can update the corresponding state information of the working device, and the state information of the working device can be changed at the moment; and after the development board detection state information is updated, acquiring the equipment information of the working equipment and the state information.

For example, the development board controls each working device (for example, including device a and device B) in the device cluster to collect data, when the device a collects temperature data, the device a stores the collected temperature data into the state information to update the state information of the device a, and at this time, the state information of the device a is changed; after the state information of the development board detection equipment A is updated, the equipment information and the state information of the equipment A are acquired; when the equipment B collects the humidity data, the equipment B stores the collected humidity data into the state information so as to update the state information of the equipment B, and the state information of the equipment B is changed at the moment; after the state information of the development board detection device B is updated, the device information and the state information of the device B are acquired.

In some embodiments, when detecting that the state of the working device changes, before the development board acquires the device information and the state information of the working device, after the working device and the development board find each other, the development board acquires the authentication information of the working device; the development board determines the equipment safety state of the working equipment according to the authentication information of the working equipment; and if the equipment safety state of the working equipment is the safety state, adding the working equipment into the equipment cluster, and connecting the development board with the working equipment through a distributed soft bus. Therefore, the safety state of the equipment of the working equipment can be determined, and the working equipment is added into the equipment cluster, so that the equipment safety of the equipment cluster is ensured.

The authentication information is used for recording authority information of the working equipment, the equipment safety state of the working equipment can comprise a safety state and an unsafe state, and the safety state is used for indicating that the working equipment can join in an equipment cluster through a distributed soft bus; the unsafe state is used to indicate that the working device cannot join the device cluster via the distributed soft bus.

Specifically, the development board analyzes authentication information of the working equipment to determine whether the working equipment is in a state meeting preset equipment safety check conditions, if the working equipment meets the preset equipment safety check conditions, the equipment safety state of the working equipment is determined to be a safety state, and if the working equipment does not meet the preset equipment safety check conditions, the equipment safety state of the working equipment is determined to be an unsafe state.

If the device security state of the working device is a security state, the working device is added into a device cluster through a distributed soft bus; and if the equipment safety state of the working equipment is an unsafe state, not adding the working equipment into the equipment cluster.

S102, classifying the working equipment by the development board according to the equipment information to obtain the equipment type of the working equipment.

Wherein the device information may be used to obtain identity information of the device, thereby determining a device type of the working device. The device types of the working device may include a temperature sensor, a humidity sensor, an infrared sensor, and the like.

In some embodiments, the development board parses the device information to obtain identity information of the working device; classifying the working equipment according to the identity information of the working equipment to obtain the equipment type of the working equipment. Therefore, the working equipment can be accurately classified, and the equipment types of the working equipment can be obtained.

The identity information of the working device may be ID information of the working device, for example, a device model number, a device code, and the like.

Illustratively, the development board parses the device information to obtain ID information of the working device, where the ID information may include one or more of a device model number, a device number, and a device code; and classifying the working equipment according to the equipment model, the equipment number and the equipment code of the working equipment, thereby obtaining the equipment type of the working equipment.

In some embodiments, determining a device model of the working device according to the identity information of the working device; acquiring a device model corresponding to a preset device type, and determining whether the device model of the working device is the same as the device model corresponding to the preset device type; if the equipment model of the working equipment is the same as the equipment model corresponding to the preset equipment type, determining that the equipment type of the working equipment is the preset equipment type. The device type of the working device can thus be determined accurately by means of the identity information.

The device model may be a device number of the working device, and in general, the device number of each device is unique and may be used to determine the device type. The preset device types may include types of temperature sensors, humidity sensors, infrared sensors, and the like.

Specifically, determining the equipment model of the working equipment according to the identity information of the working equipment; acquiring equipment models corresponding to preset equipment types, and determining whether the equipment models of the working equipment are the same as the equipment models corresponding to the preset equipment types; if the equipment model of the working equipment is the same as the equipment model corresponding to the preset equipment type, determining that the equipment type of the working equipment is the preset equipment type; if the equipment model of the working equipment is different from the equipment model corresponding to each preset equipment type, the equipment type of the working equipment is determined again.

Illustratively, determining that the equipment model of the equipment A is a model a according to the identity information of the equipment A; obtaining equipment models corresponding to preset equipment types (such as a temperature sensor and a humidity sensor), wherein the equipment models corresponding to the temperature sensor comprise an a model and a b model, and the equipment models corresponding to the humidity sensor comprise a c model and a d model); and determining whether the equipment model of the equipment A is the same as the equipment model corresponding to the temperature sensor and the humidity sensor, and determining that the equipment type of the working equipment is the temperature sensor if the equipment model of the equipment A is the same as the equipment model corresponding to the temperature sensor.

In some embodiments, classifying the working devices according to the identity information of the working devices, and determining whether the device types of the working devices are defined after obtaining the device types of the working devices; and if the equipment type of the working equipment is undefined, defining the equipment type according to the equipment information of the working equipment.

Wherein whether the device type has been defined may indicate whether the device type is stored in the development board, the device type having been defined may indicate that the device type is stored in the development board, and the device type having not been defined may indicate that the device type is not stored in the development board. Device information such as temperature sensors and humidity sensors has been defined, and when a new device such as a pressure sensor is connected, the device type is undefined, and thus it is necessary to define and then use it.

Specifically, determining whether a device type of the working device is defined; if the equipment type of the working equipment is undefined, defining the equipment type according to the equipment information of the working equipment; and if the equipment type of the working equipment is defined, sending the equipment type of the working equipment to the digital twin platform.

For example, assuming that the equipment type of the working equipment is a pressure sensor, determining whether the equipment type of the pressure sensor is defined, and if the equipment type of the pressure sensor is not defined, defining the equipment type according to the equipment information of the working equipment. The device type (pressure sensor) is stored in the development board.

S103, the development board sends the equipment type of the working equipment to the digital twin platform, so that the digital twin platform performs space mapping processing on the working equipment in a preset information model according to the equipment type and the state information, and a target information model is constructed.

The status information may include data collected by the working device or an actual status of the working device, such as in a working state or a leisure state, etc. The preset information model may include a Network of nodes (or a structured graph) composed of nodes (nodes) and References (References), and this structure is called an address space of OPC UA. Such a graphical structure may describe a wide variety of structured information (objects). The target information model may be a model obtained by performing spatial mapping on the preset information model by using the working device.

In some embodiments, the digital twin platform abstracts the working device into an abstract node according to the device type and generates structural information of the working device according to the state information; and in a preset information model, generating an address space according to the abstract node and the structural information, and constructing the target information model through the address space. Therefore, the working equipment can be subjected to abstract processing, and the target information model is constructed and obtained.

Wherein the structured information is used to represent image information of the working device in the information model. The address space is used to provide a standard way for a server to represent objects to clients. The address space is implemented by using information models, objects through variables and methods, and objects expressing relationships. The elements of the model in the address space are referred to as nodes, and node classes are assigned to the nodes to represent the elements of the object model. Objects and their components are represented in address space as a collection of nodes, which are described by attributes and are connected by references. The basic principle of OPC UA modeling is the node-to-node referencing.

Specifically, in a preset information model, an address space is generated according to abstract nodes and structured information, the address space comprises abstract nodes and node sets corresponding to the abstract nodes, reference relations between the abstract nodes and other nodes are included, and an object information model is obtained through OPC UA modeling construction through the node sets and the reference relations between the abstract nodes and the other nodes.

In some embodiments, determining a node type corresponding to the working device according to the device type; and screening the preset nodes according to the node types to obtain abstract nodes. Therefore, the abstract nodes corresponding to the working equipment can be accurately screened.

The preset nodes may include nodes corresponding to multiple device types and different device requirements, for example, may include nodes corresponding to a temperature sensor (high temperature), nodes corresponding to a temperature sensor (low temperature), nodes corresponding to a pressure sensor (high pressure), nodes corresponding to a pressure sensor (low pressure), and so on.

Specifically, the node type corresponding to the working equipment is determined according to the equipment type, the node type generally corresponds to the equipment type, and then the preset node is screened according to the node type and the equipment requirement to obtain the abstract node corresponding to the working equipment.

For example, the device type is a temperature sensor, the device requirement is a measured water temperature, and the device is generally used for measuring the water temperature. Therefore, the node type corresponding to the working equipment can be determined to be the node corresponding to the temperature sensor according to the equipment type, and then a plurality of preset nodes are screened according to the temperature sensor and the equipment requirement for detecting the high temperature, so that the abstract node corresponding to the working equipment is obtained.

In some embodiments, determining location information of the working device in the information model from the address information; determining relation information of the working equipment and other working equipment according to the position information; and generating structural information of the working equipment according to the relation information.

Wherein, because the working equipment is generally located at the site, the address information is used for representing the actual position of the working equipment at the site, and the position information is used for representing the coordinate position of the working equipment in the information model. The relation information is used for representing the connection relation between the working equipment and the rest of the working equipment and is used for determining the reference relation between the abstract node and the rest of the nodes.

Specifically, the working equipment is subjected to space mapping according to the address information, so that the coordinate position of the working equipment in the information model is determined; and generating structural information of the working equipment according to the relation information.

S104, responding to a device state acquisition instruction of the terminal device, extracting state information of the working device by the development board through the target information model, and sending the state information of the working device to the terminal device.

The device state obtaining instruction may be a request message sent by the terminal device to the development board, and is used for obtaining state information of the working device.

Specifically, after the development board receives the device state acquisition instruction sent by the terminal device, the development board determines the working device corresponding to the state information to be acquired according to the device state acquisition instruction, determines the corresponding abstract node of the working device from the target information model after determining the corresponding working device, and stores the state information of the working device in the corresponding abstract node after changing, so that the development board can acquire the state information of the working device by determining the corresponding abstract node of the working device and extracting the information from the abstract node. The method and the device have the advantages that the collected data of the working equipment are not required to be directly obtained, and the problems of data dispersion, repeated development and incompatibility of communication among the equipment in the existing scheme are avoided.
