Description

Technical Field

[0001] The present invention relates to the technical field of combining industrial Internet of Things with intelligent devices, and in particular to a data acquisition and control protocol construction system and method based on a crowd-building and crowd-sharing model. Background Art

[0002] At present, domestic industrial manufacturing, especially furniture manufacturing companies, have deployed various types of advanced automated manufacturing equipment on a large scale, covering industrial control equipment, logistics warehousing systems, robots, and special process equipment. These high-tech equipment have significantly improved production efficiency and product quality, but they have also brought new challenges: because different brands and models of equipment use a variety of interfaces, communication protocols and data formats, they encounter serious heterogeneity barriers when accessing the production line system. This makes it particularly difficult to seamlessly integrate these devices into the industrial Internet required for intelligent manufacturing. If you choose to directly eliminate existing manufacturing equipment to achieve a comprehensive upgrade, it will not only cause a huge waste of investment, but also be inconsistent with the concept of sustainable development. Therefore, a more realistic and cost-effective solution is to bridge this "gap" by introducing industrial gateway technology.

[0003] As a key connection hub, the industrial gateway can enable various edge manufacturing equipment to smoothly access the industrial Internet without changing the original hardware facilities, ensuring that they can be "connected to the network and integrated into the cloud", thereby realizing functions such as data interoperability, resource sharing, and remote monitoring, helping enterprises to transform and upgrade to intelligentization.

[0004] One of the biggest challenges in building industrial gateways is that there are many types of industrial equipment and different models, resulting in great diversity in interfaces, protocols, data formats, and application scenarios. According to statistics, there are hundreds of industrial control protocols, dozens of CNC protocols, nearly a thousand types of robots, and tens of thousands of process equipment in the domestic market alone. Faced with such a large number of equipment and a complex protocol system, even the most powerful companies find it difficult to develop an industrial gateway product that is versatile enough to be compatible with all existing industrial control protocols and technical standards.

[0005] In fact, in any particular sub-industry, it is extremely difficult to develop a universal industrial gateway that can meet a wide range of needs and ensure high compatibility. This is because each type of equipment has its own unique characteristics and requirements. Therefore, how to effectively deal with the challenges brought by this diversity has become a common concern and urgent problem for the manufacturing industry at home and abroad. That is, the research and development and application of universal industrial gateways are still a major problem that hinders the integration of manufacturing equipment and the integration of manufacturing equipment into the industrial Internet. Summary of the invention

[0006] The purpose of the present invention is to provide a data acquisition and control protocol construction system and method based on a crowd-building and crowd-sharing model to solve the above-mentioned technical problems.

[0007] To achieve the above-mentioned purpose, the present invention provides a data acquisition and control protocol construction system based on a crowd-building and crowd-sharing mode, including a software-definable industrial gateway and a sharing platform, wherein the sharing platform is deployed on a cloud platform and is used to provide a variety of protocol parsing microservice management entities based on a microservice framework and data acquisition and control software; The software-definable industrial gateway includes a collection device connected to the production equipment, which is used to download the data collection and control software and protocol parsing microservices matching the production equipment from the shared platform to the collection device, and collect and control the production equipment based on the data collection and control software, while providing intermediate gateway support for third-party control equipment; Data acquisition and control software runs as microservices in software-definable industrial gateways and acquisition devices.

[0008] Preferably, the sharing platform is managed and operated by the operator, and has the functions of uploading, registering in the database, updating, reviewing, user registration and authentication, demand search, downloading, feedback, deletion, demand publishing, purchase transaction, disaster recovery backup and limited-time trial of data collection and control software.

[0009] Preferably, the acquisition device adopts the architecture of MCU-industrial control interface-communication interface, wherein the MCU runs a data acquisition and control protocol that can be dynamically loaded online; the industrial control interface includes one of CAN, serial port, Profinet, industrial Ethernet and any combination thereof; the communication interface includes one of LAN, WIFI, 3G, 4G, 5G and any combination thereof; The MCU of the collection device interacts with the software-definable industrial gateway to collect data through the communication interface.

[0010] Preferably, the software can define the industrial gateway to be designed with reference to the edge computing architecture. At the network level, it is connected to the collection equipment through at least one transmission method among LAN, WIFI, 3G, 4G, and 5G to realize data collection of various types of production equipment; In terms of computing and storage, it uses an industrial CPU and is configured with DDR RAM, has high-performance processing capabilities, supports edge computing technology, collects data from software-definable industrial gateways on each node for computing and processing, and transmits the processed valid data to a shared platform to reduce the computing burden of the network and system.

[0011] Preferably, the software-definable industrial gateway has a common hardware architecture and is located close to production equipment.

[0012] Preferably, the multiple protocol parsing microservice management entities include PLC parsing service, robot protocol parsing service, industrial control data processing service and CNC data processing service.

[0013] The method for constructing a data collection and control protocol based on a crowd-building and crowd-sharing model includes the following steps: S1.

Data acquisition and control implementation: Demanders can use software to define industrial gateways to search and download data collection and control software corresponding to production equipment models from a shared platform, and perform data collection and control on production equipment based on the data collection and control software.

[0014] Preferably, in step S4, when the demander fails to search for the data acquisition and control software corresponding to the production equipment model on the sharing platform, the demander publishes the demand information on the sharing platform, and the sharing platform publishes the demand information to the developer. The developer matches the software type that he has the development capability with the equipment model in the demand information, determines the data acquisition and control software that matches the equipment model, uploads it to the sharing platform, and forwards it to the demander by the sharing platform.

[0015] Preferably, in step S4, when the data acquisition and control software is in trial mode, when the software trial period ends, it is determined whether the demander has completed the payment. If the payment is not completed, the software trial is stopped, and the application market notifies the software to define the industrial gateway and acquisition device to delete the trial data acquisition and control software to realize software controlled transactions; otherwise, it switches to normal mode.

[0016] Preferably, in step S4, the demander logs in to the sharing platform to search for the required protocol parsing microservice; if the protocol parsing microservice is found and the purchase is completed, the demander downloads the protocol parsing microservice from the sharing platform, and if the demander finds any problem during the use of the protocol parsing microservice, the demander feedbacks the problem to the sharing platform.
