[0001] The present invention relates to the field of device access technology in industrial Internet and Internet of Things, and more specifically to a Link Assistant access method and system for multi-mode and multi-level device access on an industrial Internet platform. Background Art

[0002] In the process of digital transformation, enterprises often face problems such as decentralized and duplicated IoT systems, inconsistent manufacturing data, and difficulty in data sharing and value release. With the development of the industrial Internet platform, the above problems have been solved to a certain extent. At present, the industrial Internet platform is already very powerful in IoT capabilities and can support the access and management of large-scale equipment. In the prior art, the patent with publication number CN116319375A discloses a test method and device for connecting IoT devices to an industrial Internet platform. The method includes: creating a data model of multiple IoT devices on the industrial Internet platform; for each IoT device, forming a string of unique identification and collected data of the IoT device as the content sent by mqtt; adding an mqtt plug-in to Jmeter, starting jmeter, and establishing a new thread group; based on the data models of multiple IoT devices under the thread group, using a test thread to simulate multiple IoT devices connecting to the industrial Internet platform, wherein, based on the data model, the content sent by mqtt is filled into the test thread through the mqtt plug-in during simulation; starting the thread group, observing the content sent by the IoT device; and analyzing the test results of each IoT device based on the content sent. The present invention can simulate IoT devices, can perform multiple tests, and has no test message delay.

[0003] The patent with publication number CN115987982A discloses a system and method for edge devices to access the industrial Internet cloud platform. The system includes: an edge layer, the edge layer includes a client, and the client interacts with the intelligent gateway in a question-and-answer manner; it also includes an access layer, and the access layer includes an intelligent gateway; the client and the intelligent gateway use the Socket communication technology based on the TCP / IP protocol as a communication interface; the system also includes a platform layer, and the platform layer interacts with the client through the access layer. Compared with the traditional method of edge devices accessing the cloud platform, this application adds numbering information to the interactive information, and by binding the numbering information with the device end and the platform layer, when the device end (client) needs to send a class of data packets to the intelligent gateway multiple times, in the event of an interruption in the data transmission process or the need to resend the data multiple times, the client needs to adjust the data identifier according to the data sent each time.

[0004] The patent with publication number CN114422873A discloses a method, device and equipment for dynamically accessing the industrial Internet identity resolution platform. It aims to solve the problem that the existing data monitoring of industrial equipment cannot directly access the industrial Internet or cannot achieve access to all on-site equipment. By uniformly connecting the on-site equipment, systems or scattered collection points to the collection device, and then flexibly defining the virtual devices that need to be dynamically connected to the industrial Internet identity resolution platform through the collection software configuration, it is finally possible for various on-site instruments to quickly obtain the industrial Internet identity and dynamically access the industrial Internet identity resolution platform, and realize visual data monitoring of the equipment.

[0005] The patent with publication number CN115643072A discloses an edge device management method, system, device and medium based on the industrial Internet. The method includes: registering the edge device on the industrial Internet platform so that the edge device is bound to the security device; using the security device to connect the edge device to the industrial Internet platform; using the security device to communicate between the edge device and the industrial Internet platform. The present invention realizes dual authentication of device identity and real-time location, flexibly supports device update scenarios, and improves the security of device access and device communication.

[0006] According to the description of the device access process in the above patent, the device access process can be combined and organized into the following key steps: ① Equipment access preparation: Before accessing the device, you need to prepare the device, including confirming the device type, communication protocol, data format and other information, and ensuring that the device has network connection function.

[0007] ② Equipment registration: Register the equipment information to the Industrial Internet platform, including equipment identification, equipment attributes, location and other information, so that the platform can identify and manage the equipment.

[0008] ③ Device connection: According to the communication protocol and access method of the device, configure the connection between the device and the industrial Internet platform to ensure that the device can exchange data and communicate with the platform.

[0009] ④Data collection: Once the device is successfully connected to the platform, the platform begins to collect data from the device, including device status, sensor data, operation logs and other information.

[0010] ⑤ Data transmission and processing: The collected data is processed and transmitted to the industrial Internet platform. The platform will store, analyze and display the data, and support users' real-time monitoring and data analysis.

[0011] ⑥ Remote monitoring and control: Through the industrial Internet platform, users can realize remote monitoring and control of equipment, including remote equipment management, parameter configuration, fault diagnosis and other functions.

[0012] Based on the above patent results, incremental industrial equipment can be efficiently connected.

[0013] However, the digital transformation of enterprises is not achieved overnight. The transformation of enterprises often takes several years or even more than ten years. In this process, various existing point-based IoT systems (such as workshop SCADA, energy management system, EAM equipment management system, etc.) serving specific scenarios will inevitably be built due to the demand for point-based IoT scenarios. The current access methods often do not care about or consider the access of existing devices, which leads to the loss of information on existing devices. There are still information islands between incremental and existing devices, and the devices cannot be interconnected and interoperable.

[0014] In addition, compared with traditional point-based IoT systems, industrial Internet platforms often show hierarchical capabilities, that is, industrial Internet platforms are usually developed based on "cloud-edge" or more complex architectures, and industrial Internet platforms at different levels manage the status of various production tools and industrial equipment from different management dimensions. Traditional access methods can also push data to various platforms one by one through the principle of multi-channel forwarding, but they cannot reflect the management focus of different management levels, and it is even more difficult to form an enrichment effect of multi-level equipment management knowledge and experience, and it is difficult to form an innovative development model driven by digital intelligence. Summary of the invention

[0015] In order to overcome the defects in the above-mentioned prior art, the present invention discloses an industrial Internet platform device access method and system. The present invention divides multi-source heterogeneous devices into four access categories (device direct access, device gateway access, device application access, and device platform access), and solves the problem of multi-mode and multi-level device access to the industrial Internet platform in one stop through a unified Link Assistant access module.

[0016] In order to achieve the above objectives, the technical solution adopted by the present invention is: An industrial Internet platform device access method, the access method comprising: based on device direct access, device gateway access, device application access, and device platform access, using an access module to access the access device to the industrial Internet platform, specifically comprising the following steps: S1, determine whether the access device is multi-layer access, if so, access the device using the device platform access method, if not, go to step S2; S2, determine whether the access device is incremental access, if not, it is stock access and access the device using the device application access method, if so, enter S3 step; S3, determine whether the access device is accessed using a gateway, if so, access the device using the device gateway access method, if not, proceed to step S4; S4. Use the device direct connection method to access the device.

[0017] In the present invention, first determine whether it is multi-layer access, then determine whether it is incremental access, and finally determine whether gateway access is used. The reason for this sequential determination is: first determine whether it is multi-layer access because the essence of multi-layer access is cloud-edge collaboration, which belongs to data transmission within the platform. This judgment divides the data source into internal and external; then determine whether it is incremental access because the source of external data includes two categories: devices and applications. This judgment further divides the data source into external device access and external application access; finally determine whether gateway access is used because the external device access methods include direct connection and gateway access. This judgment further divides external devices into external direct connection devices and external gateway devices. In summary, the above judgments are designed according to the data source (internal and external), data carrier form (platform and device) and data carrier category (direct connection and gateway).

Configure the connection device of the selected access mode, including configuring network parameters and communication protocols; C5.
