Embodiment 1

[0031] In this embodiment, an edge cloud industrial data management system based on a publish-subscribe mechanism and delay analysis is provided, including

[0032] Data source; used to collect industrial field data;

[0033] Edge cloud server; used to deploy various industrial data applications;

[0034] 5G base station; used to receive the industrial field data transmitted by the data source through 5G, and upload the industrial field data to the edge cloud server;

[0035] Each of the edge cloud servers is deployed inside the 5G base station, and a direct connection is used for data transmission between the two;

[0036] Each of the edge cloud servers includes:

[0037] Delay analysis module; used to calculate the data transmission delay time between edge cloud servers;

[0038] Data management module; used for data publishing and subscription and data cache management;

[0039] Data application module; used to access data sources required by industrial data application...

Embodiment 2

[0042] like figure 1 As shown, in this embodiment, an edge cloud industrial data management method based on a publish-subscribe mechanism and time delay analysis is provided, and the management method is implemented using a management system; the management method specifically includes three steps, which are: Delay analysis stage, data publishing and subscription stage, data access stage. The following is a detailed description of each stage:

[0043] 1. Time delay analysis stage, corresponding to the content of step S1, step S1 is specifically:

[0044] The delay analysis module of each edge cloud server sends detection frames to other edge cloud servers respectively, receives the ark frames transmitted by the other party, and analyzes the transmission delay according to the sending time of the detection frames and the receiving time of the ark frames; each edge cloud server The server obtains a delay data table;

[0045] As an example to illustrate step S1, it is assumed ...

Embodiment 3

[0072] In this embodiment, the industrial data management system and management method are specifically described by taking the industrial cloud organizational structure of a group as an example.

[0073] If the group-type industrial cloud is distributed in city A and city B; city A has three campuses, each with one edge cloud server and one 5G IoT; city B has four campuses, each with one edge cloud server and one 5G IoT Networking; cities are connected through a wide area network. Due to the long distance between the cities, the data transmission speed is slow; the city is connected through a metropolitan area network, and the data transmission speed is fast due to the short distance between the parks in the same city.

[0074] When the edge cloud server A1 in city A accesses the data of the sensor covered by the edge cloud server B2 in city B.

[0075] The edge cloud server A1 will first request the other two edge cloud servers A2 and A3 in city A (assuming that both A2 and ...

Abstract

The invention discloses an edge cloud industrial data management system and method based on a publish-subscribe mechanism and time-delay analysis. The management system includes a data source; used for collecting industrial field data; an edge cloud server; used for deploying industrial data applications; and a 5G base station ;It is used to receive the industrial field data transmitted by the data source through 5G, and upload the industrial field data to the edge cloud server; each edge cloud server is deployed inside the 5G base station, and the data transmission is performed by direct connection between the two; the edge cloud server Including delay analysis module; used to calculate the delay time of data transmission between edge cloud servers; data management module; used for data publishing subscription and data cache management; data application module; used to access the data sources required by industrial data applications . The advantages are: through the publish and subscribe mechanism, the global awareness of data subscription information is realized; through delay analysis, low-latency reading of data is realized; through data caching, the reliability of data reading is improved.

Description

technical field [0001] The invention relates to the technical field of data management, in particular to an edge cloud industrial data management system and method based on a publish-subscribe mechanism and time delay analysis. Background technique [0002] The fifth generation mobile communication technology (abbreviated as 5G) is the latest generation of cellular mobile communication technology, and it is also an extension after 4G, 3G and 2G systems. The performance goals of 5G are high data rates, reduced latency, energy savings, lower costs, increased system capacity, and massive device connectivity. [0003] In the context of 5G, the amount of data is large and there are many computing tasks. If the classical centralized cloud computing method is adopted, due to the long data transmission distance, it will bring a large delay. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide an edge cloud industrial data management system and meth...
