Background Art

[0002] With the rise of Industry 4.0, manufacturing and other industrial fields are undergoing rapid digital and intelligent transformation. Traditional industrial communication systems usually rely on wired networks, which face problems such as slow data transmission, high latency, insufficient bandwidth and poor scalability. These limitations affect the efficiency and flexibility of industrial production.

[0003] In recent years, the rapid development of 5G technology has provided new possibilities for solving these problems. 5G networks meet the needs of real-time data transmission and efficient communication in industrial environments. Especially in real-time monitoring and control systems, the advantages of 5G are particularly prominent, which can significantly improve data processing speed and system responsiveness, thereby supporting more complex and sophisticated industrial operations. However, there are still many challenges in effectively applying 5G technology to industrial communication systems, such as network coverage and reliability. Therefore, industrial communication systems based on 5G networks combined with load technology give full play to the potential of 5G technology and solve the shortcomings of existing technologies.

In actual use, when an abnormal state of the gas cylinder is detected, the closure of the gas cylinder can also be remotely controlled, further ensuring the safety of use. Although this invention patent application monitors the gas cylinder through a variety of sensor devices and 5G networks, it does not monitor and adjust the 5G network link, and cannot guarantee the reliability of 5G communication data transmission.

It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0037] An embodiment of the present invention discloses an industrial communication system based on a 5G network, including: a network link acquisition module, a communication load balancing module, a distributed data acquisition module, a data analysis and statistics module, and a visualization module.

[0038] The network link acquisition module uses a 5G communication interface to collect network traffic data on the communication link in real time. In the embodiment of the present invention, the network traffic data includes but is not limited to key indicators such as bandwidth occupancy, packet loss rate, and delay. The network link acquisition module uses efficient data storage and transmission technology to transmit network link traffic data to the communication load balancing module.

[0039] The communication load balancing module uses a dynamic weight allocation algorithm to analyze the link load status based on the collected network traffic data, identify bottlenecks and potential high-load areas, and schedule distributed collection modules in real time according to the analysis results to achieve dynamic traffic balancing, optimize network performance, and ensure the stability and efficiency of data transmission.

[0040] In the embodiment of the present invention, the communication link load calculation formula used by the communication load balancing module is as follows:

[0042] Where n i is the number of nodes included in the communication link, K i is the load balancing coefficient, x(t) is the real-time collected communication link traffic data, and Y i is the link load.

[0043] Taking into account the 5G communication capacity, the current link load detection result can be obtained. The capacity calculation formula is:

[0044] C i =m dct (W(i)+B(i))

[0045] In the formula, m dct is the matrix determinant function, W(i) and B(i) are the communication link unit matrix and bandwidth value, which can be obtained from the communication link acquisition module, C i is the communication link capacity.

[0046] Furthermore, the communication load balancing module The detection results of the load level of the 5G communication link are obtained.

[0047] After obtaining the load status of the 5G communication link (i.e., the detection result of the load degree of the 5G communication link), the link with load congestion is scheduled and controlled to alleviate the congestion degree. The communication link congestion load control amount ΔF jam (i) is:

[0048]

[0049] In the formula, δ is the load level of the communication link, δ0 is the setting threshold, and the load balancing control amount ΔF is calculated according to the congestion load control amount balanced (i)

The data acquisition devices transmit data to the distributed data acquisition module through the 5G network using the MQTT protocol / HTTP protocol. The distributed data acquisition module adjusts the distributed strategy in time according to the communication link load analysis results.

[0055] According to the communication link control quantity result, if the communication link control quantity result of the current link is positive, the load of the current link needs to be scheduled to other links, that is, the distributed link scheduling information containing the negative communication link control quantity result is transmitted to the data acquisition device of the current link through the distributed acquisition module, and the data acquisition device that receives the distributed link scheduling information connects other distributed communication links for data transmission based on the scheduling information.

[0056] The data analysis and statistics module is used to conduct in-depth analysis and statistics on the data uploaded by the distributed data acquisition module. It mainly uses data mining and other technologies, including: data cleaning, data classification, data statistics, data analysis, to achieve industrial communication system energy consumption analysis, production efficiency evaluation, equipment failure warning, product quality monitoring and other functions.

[0057] The visualization module develops a user-friendly visualization interface to display key information such as network link traffic, various production data, and analysis results in real time. In the embodiment of the present invention, the visualization module supports multiple visualization forms, such as dashboards, line charts, heat maps, etc., to help managers intuitively understand the production status, quickly discover problems and respond.

[0058] In the technical solution disclosed in the embodiment of the present invention, the data acquisition device establishes a communication connection with the distributed acquisition module through the 5G network, the network link acquisition module collects traffic data in real time, and the distributed data acquisition module performs dynamic link adjustment according to the analysis results of the communication load balancing module to ensure efficient and stable transmission of various types of production, quality and other data.

The industrial communication system can collect, process and visualize various data in the industrial production process in real time, providing strong technical support for production management. At the same time, by optimizing the configuration of communication links and data analysis statistics, it effectively improves the stability and reliability of data transmission, reduces the data transmission delay, and provides a strong guarantee for the intelligent transformation of industrial enterprises.
