According to the industrial equipment metadata storage method, an Internet of things platform obtains first metadata corresponding to target industrial equipment transmitted by gateway equipment, determines a target data format corresponding to the target industrial equipment, then obtains a target format analysis script template corresponding to the target data format, analyzes the data format of the first metadata by adopting the target format analysis script template to obtain target metadata, wherein the data format of the target metadata is the target data format, and stores the target metadata; the method realizes the data filtering of the metadata of the industrial equipment and reduces the pressure of the internet of things platform for storing the data.
The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
FIG. 1 is a flow chart of an industrial device metadata storage method provided herein. As shown in fig. 1, the method for storing metadata of industrial equipment provided in this embodiment includes:
s101: and acquiring first metadata transmitted by the gateway equipment, wherein the first metadata is obtained by analyzing a first transmission protocol corresponding to the target industrial equipment through an analysis script template by the gateway equipment.
The first metadata is used for indicating the industrial equipment to correspond to a large number of data stored to the gateway equipment in different format types.
Industrial equipment types and brands are numerous, metadata format types generated by different industrial equipment types are different, and the corresponding first transmission protocols cannot be unified. Therefore, metadata generated by the industrial equipment cannot be directly stored in the internet of things platform, and the gateway equipment is required to analyze and transmit the metadata corresponding to the industrial equipment.
Gateway devices play a role in data transmission in an environment monitoring system, and data acquisition is one of the core functions of an industrial gateway in the modes of 4G, ethernet, WIFI, RS485 and the like, because the data of the industrial device can be acquired and sent to an Internet of things platform through data acquisition, the following is the principle of the gateway device for acquiring the data:
1) Data acquisition unit: the data are collected into the gateway equipment through connecting sensors, industrial equipment and the like, and common data collection modes comprise digital quantity input, analog quantity input, serial port input, ethernet input and the like;
2) And (3) data processing: the gateway device extracts valuable information by processing the collected data, and generally comprises operations such as data verification, protocol conversion, data analysis, data storage and the like so as to ensure the accuracy and the integrity of the data;
3) And (3) data transmission: after data processing, the gateway device transmits the data to the internet of things platform or other devices through a network, wherein the transmission mode comprises the following steps: ethernet, WIFI, bluetooth, GPRS, etc.;
4) And (3) data storage: the gateway equipment stores the collected data in a local or cloud end for subsequent data analysis, control and other purposes;
in general, the data acquisition principle of the gateway equipment is that the data acquisition is performed through the collector, and the acquired data is transmitted to the internet of things platform or other equipment through the steps of data processing, transmission, storage and the like, so that the functions of real-time monitoring, control, debugging and the like are realized.
The gateway device may mount a direct connection device of the sub-device. The gateway equipment is provided with a sub-equipment management module which can manage the topological relation between the gateway equipment and the sub-equipment; the gateway sub-equipment cannot be directly connected with the internet of things platform and can only access the equipment of the internet of things platform by means of the gateway equipment.
Because the gateway of different manufacturers analyzes that the rule of the same type of industrial equipment corresponding to the first transmission protocol is different, in order to ensure the integrity of the metadata received by the internet of things platform, the gateway equipment is set as follows: and as long as the object numbered musical notation message format is met, the data can be forwarded and stored to the Internet of things platform. The process can lead to the data of non-production processes of some industrial equipment to be stored, occupy more resources over time, and increase the pressure of data storage of an Internet of things platform.
In order to avoid that data of non-production processes of some industrial equipment are saved, resources of the Internet of things platform are occupied. Some gateway vendors may provide script development capability to parse the message data format by writing script code before forwarding the data, filtering the data. Although this approach can solve the problem of different message data formats to some extent, there are a number of drawbacks, such as: the threshold is high, a certain requirement is provided for development skills of personnel, and the script needs to be encoded and developed; the efficiency is low, a large amount of codes and debugging are required for script development, and a large amount of time and cost are consumed; the reusability is poor, the gateways of each manufacturer are different in brands corresponding to the gateways, the analysis of the script written each time on the message data format is limited to the gateway of a certain brand, the script is required to be rewritten for the gateways of other brands, and a unified message data analysis template is not available.
Therefore, the first metadata, which is transmitted by the gateway device and is obtained by analyzing the first transmission protocol corresponding to the target industrial device through the analysis script template, is firstly obtained, and the internet of things platform stores and filters the first metadata.
S102: and determining a target data format corresponding to the target industrial equipment, and acquiring a target format analysis script template corresponding to the target data format.
The target industrial equipment is used for indicating the industrial equipment created by the Internet of things platform. The target data format is used for indicating a data format corresponding to data generated in the industrial equipment production process created by the Internet of things platform. The target format analysis script template is used for analyzing a data format corresponding to data generated in the production process of industrial equipment created by the Internet of things platform.
It can be understood that, after the first metadata transmitted by the gateway device is obtained, in order to store the target metadata, the internet of things platform can determine the data format of the first metadata transmitted by the gateway device first, and after the first metadata is determined according to the data format, the internet of things platform is different from the data storage mode of the industrial device, so that the format analysis script template is required to analyze the first metadata, not only the data in the production process of the non-industrial device is filtered, but also the first metadata is required to be converted into the data storage mode corresponding to the internet of things platform for storage.
Before storing metadata of industrial equipment, the Internet of things platform needs to define information such as product names, node types (industrial equipment selects gateway sub-equipment, gateway equipment selects gateway equipment), transmission protocols and the like by creating industrial equipment (such as an injection molding machine) and gateway equipment (such as a Kaos Internet of things gateway), and creates a physical model of the configured product after the industrial equipment and the gateway equipment products, wherein the physical model comprises detection points and attribute states; after the product and the object model are established, industrial equipment (for example, no. 1 injection molding machine) and gateway equipment (No. 1 Kaos Internet of things) are established, and when the industrial equipment and the gateway equipment are established, the product of the equipment needs to be selected, and the basic information and the object model configuration of the product are inherited; and binding the No. 1 injection molding machine (sub-equipment) at a sub-equipment management interface of the No. 1 Kaois Internet of things gateway.
The object model is a digital representation of an entity in a physical space in an internet of things platform, and is a data model attached to equipment. The measurement points represent point location data that the device can be monitored, for example: yield of the apparatus. The attribute represents a device operational attribute that is distinguished from the measurement point by a low frequency of data changes and is more focused on the current value, such as: device operating state.
A device is a unit having the capability of transmitting data, which corresponds to a physical device in a physical space, such as: and the smoke sensor is specifically arranged at the top of a workshop.
S103: and analyzing the data format of the first metadata by adopting the target format analysis script template to obtain target metadata, wherein the data format of the target metadata is the target data format, and storing the target metadata.
The target metadata are used for indicating metadata generated in the production process of the corresponding industrial equipment of the Internet of things platform to be converted into metadata which can be stored in the Internet of things platform.
It can be understood that the internet of things platform performs configuration of analysis rules on the data format analysis interface, selects the processing type of metadata (different processing types correspond to different data formats) according to the data format standard of the internet of things platform, generates a format analysis script, adjusts the script according to actually required equipment data, selects a product to be applied (for example, a Kaos internet of things gateway), clicks a debugging button to analyze the format of the metadata, generates a target data format, displays the analyzed target data format and target metadata, and realizes data filtering of the metadata while generating the target metadata.
After the first metadata format analysis is completed by the Internet of things platform, a user can check real-time equipment telemetry data (such as temperature and other information of an injection molding machine No. 1) or attributes (such as state of the injection molding machine No. 1) pushed by entity industrial equipment on an equipment management-object model management interface; in addition, by means of a rule chain of the internet of things platform, storage and forwarding of the analyzed target metadata can be automatically achieved, and based on the forwarding function, integrated application with other systems can be achieved.
According to the industrial equipment metadata storage method, first metadata transmitted by gateway equipment are obtained, the gateway equipment analyzes a first transmission protocol corresponding to target industrial equipment through an analysis script template, a target data format corresponding to the target industrial equipment is determined, a target format analysis script template corresponding to the target data format is obtained, the target format analysis script template is adopted to analyze the data format of the first metadata, target metadata is obtained, the data format of the target metadata is the target data format, and the target metadata is stored; the method realizes the data filtering of the metadata of the industrial equipment and reduces the pressure of the internet of things platform for storing the data.
Fig. 2 is an interaction diagram of an industrial device metadata storage method according to an embodiment of the present application. As shown in fig. 2, this embodiment is a detailed description of an industrial equipment metadata storage method based on the embodiment of fig. 1, where the industrial equipment metadata storage method provided in this embodiment includes:
s201: the industrial equipment collects second metadata and generates a first transmission protocol according to the second metadata.
Wherein the second metadata is used to indicate raw data generated by the industrial equipment during production.
The method for acquiring data by the industrial equipment can comprise the following steps: sensor acquisition, instrument acquisition, computer interface acquisition, wireless data acquisition, human-computer interface and data log recorder.
And (3) sensor acquisition: various sensors are used to measure and collect various parameters such as temperature, pressure, flow, humidity, vibration, etc. The sensor converts the physical quantity into an electrical signal, which is then collected and processed using a data collection device.
Instrument measurement: specific electrical or electronic parameters are measured and collected using special measuring instruments, such as oscilloscopes, spectrometers, multimeters, etc. These instruments typically have built-in data acquisition functions that can record and store measurement data.
Computer interface: connected to various devices and sensors through computer interfaces, such as serial ports, parallel ports, USB, ethernet, etc. These interfaces allow the computer to exchange and communicate data with external devices, and software can be used for data collection and processing.
And (3) wireless data acquisition: wireless data acquisition is achieved using wireless sensors and communication technologies, such as Wi-Fi, bluetooth, zigbee, and the like. The wireless sensor transmits the acquired data to a receiving device, such as a base station or a receiver, through wireless communication.
Human-machine interface (HMI): data is collected by an operator manually entering or triggering events through human interface devices such as touch screens, keyboards, buttons, etc. This approach is often used in operational control, equipment status monitoring, and other scenarios.
Data log logger: data is recorded and stored using a data logger or data logger. These devices typically have multiple input channels, which collect and record data for multiple parameters, which may be downloaded and analyzed by a storage medium (e.g., memory card) or connected to a computer.
S202: the industrial device sends the second metadata to a gateway device using a first transmission protocol.
Wherein the first transmission protocol is used for indicating to provide service functions for the gateway device. In order to provide such a service function, the gateway device incorporates data in the industrial device into the data field of the gateway device and then implements the gateway device service function by adding a header or trailer, a process called data encapsulation. The second metadata of the industrial equipment is subjected to secondary packaging, and finally converted into signals which can be transmitted on a network and sent to the gateway equipment.
The industrial equipment (for example, no. 1 injection molding machine) is connected with gateway equipment (for example, no. 1 Kaos Internet of things) and is configured with an industrial equipment acquisition point location through the gateway equipment, a first transmission protocol corresponding to the industrial equipment is set, and connection between the industrial equipment and the gateway equipment is established.
S203: and the gateway equipment analyzes and processes the first transmission protocol corresponding to the target industrial equipment to obtain first metadata acquired by the target industrial equipment.
The first metadata is used for indicating metadata which can be obtained by analyzing the first transmission protocol in the gateway equipment.
The first metadata differs from the second metadata in that: the first metadata is data obtained after the gateway processes the second metadata; the format of the first metadata is different from that of the second metadata, which is mainly determined by the properties of the industrial equipment and the gateway equipment; the first metadata is obtained by arranging the second metadata, and the regularity of the first metadata is stronger than that of the second metadata.
And the gateway equipment analyzes the transmission protocol of the industrial equipment according to the configuration information to obtain metadata transmitted by the industrial equipment.
S204: and the gateway adopts a second transmission protocol to send the first metadata to the Internet of things platform.
The second transmission protocol (which may be the MQTT protocol) is a protocol designed for communication between remote sensors and control devices in a low bandwidth, unreliable network with limited computational power, and has the following main several characteristics:
1) Providing one-to-many message publication using a publish/subscribe message schema, decoupling the application;
2) Message transmission to load content mask;
3) Providing network connectivity using TCP/IP;
4) There are three message distribution qualities of service:
