Problems solved by technology

[0004] However, in the existing technology, for the storage of edge computing gateway data, there are the following problems: 1) It is difficult to guarantee the consistency of data in the same cycle; 2) The speed of persistent storage and update is slower than that of memory operation. Data inconsistency; 3) Data query efficiency is low, and data management efficiency requires the gateway to have powerful hardware resources or software capabilities

Embodiment 1

[0024] combine figure 1 As shown, an edge computing gateway data storage method of the present invention is applied to various industrial devices in the industrial system, and the edge computing gateway collects data of each industrial device. The present invention can store various devices in the edge computing gateway The data is stored synchronously to ensure the cycle consistency of the data of each device. Method concrete steps of the present invention are:

[0025] (1) Store data to memory

[0026] First, establish n linked lists in the memory according to the number of devices, each linked list has m nodes, and n and m are both integers; further, linked lists are associated with devices one by one, that is, a linked list is set for each device Used to store data. For data storage in the memory cache, the specific process is as follows:

[0027] Transfer the real-time data of n devices acquired at the same time to the memory cache, specifically, synchronously store t...

Embodiment 2

[0042] The content of this embodiment is basically the same as that of Embodiment 1. The specific process of storing data in the persistent storage space in this embodiment is as follows:

[0043] Real-time data includes configuration information. When the configuration information of a certain device changes at time t, the data of n devices stored in memory during the period from the last change time t0 to time t is saved to the persistent storage space, where t0 ∈[0,1,2...t]. That is, whenever the configuration information of a certain device changes, the data of all devices in the corresponding period stored in the memory is stored in the persistent storage space.

[0044] Specifically, a time wheel is established in the persistent storage space. When there is a change in the configuration information of the device, a grid is added to the time wheel according to the change in configuration information; that is, when there are L configurations in the total time period corres...

Abstract

The invention discloses a method and system for storing edge computing gateway data, and relates to the technical field of data management. The method of the present invention is as follows: set up n linked lists in memory, each linked list is provided with m nodes, and the linked lists are associated with devices in one-to-one correspondence; at the same time, real-time data of n different devices are obtained, and then the data of n different devices are The real-time data is synchronously stored to the nodes of the corresponding linked list, wherein the time interval between the start time and the end time of each node storing data is the same, and the data stored by n different devices at the same time is stored in the same node number of the corresponding linked list. The system of the present invention includes a memory and a processor; the memory is used to store computer programs, and the processor is used to execute the computer programs to realize the above method. The purpose of the present invention is to overcome the problem that it is difficult to ensure the synchronization of gateway data storage in the prior art. The present invention can ensure the periodic consistency of gateway data and realize fast query of gateway data.

Description

technical field [0001] The present invention relates to the technical field of data management, and more specifically, to a method and system for storing edge computing gateway data. Background technique [0002] Originating from the media field, edge computing refers to an open platform that integrates network, computing, storage, and application core capabilities on the side close to the source of objects or data, and provides the nearest end services. Its applications are launched on the edge side to generate faster network service responses and meet the basic needs of the industry in terms of real-time business, application intelligence, security and privacy protection. Edge computing sits between the physical entity and the industrial connection, or on top of the physical entity. With cloud computing, historical data from edge computing can still be accessed. [0003] In the existing technology, industrial system equipment will generate massive industrial data, which ...
