Abstract

The invention discloses an intelligent linkage method for smart cities with edge-cloud collaboration, and relates to the technical fields of edge-cloud collaboration and smart cities. The method configures general linkage rules on the cloud side, and once the system detects a linkage event, it will call the device immediately Carry out linkage tasks to realize automated and intelligent processing of urban events; during the execution of linkage tasks, a strategy of edge-cloud collaboration is adopted: the edge side performs equipment control and simple or preliminary data processing; the cloud side is responsible for complex data In-depth analysis and processing, as well as resource scheduling tasks across edge gateways and multiple edge gateways. The advantages of the present invention are: the configuration of general linkage rules is more suitable for the scenario of massive devices in smart cities, and the flexibility is higher; the strategy of edge-cloud collaboration is used in the linkage process, which allows complex scene linkage and reduces linkage event processing Time, improve linkage efficiency, but also slow down the cloud-side mass storage, computing and network bandwidth pressure.

Description

technical field

[0001] The invention relates to the technical field of edge-cloud collaboration and smart city, in particular to an intelligent linkage method for edge-cloud collaboration in a smart city. Background technique

[0002] At present, when configuring linkage rules in the linkage method based on the Internet of Things, it is generally necessary to specify a specific device terminal. In the smart city scenario, since a large number of devices are connected, and there are multiple devices of each type, at this time, it is necessary to configure multiple sets of linkage rules of the same type according to the configuration method of specific devices. The process is very cumbersome. And when the linkage link changes, multiple rules need to be modified, which lacks flexibility.

[0003] On the other hand, data in smart city scenarios are geographically dispersed, and intelligent real-time data collection, transmission, processing, and execution become particularly im...

Examples

Embodiment

[0035] Such as figure 1 As shown, the present invention provides a structure between the device terminal, the edge side and the cloud side in a smart city, specifically including:

[0036] Equipment terminal refers to each specific equipment, which is the most basic facility in a smart city, and is used to monitor various operating conditions of the city and provide public services for various areas of the city; various types of equipment will be deployed in public places in various areas of the city, Covering the entire city; devices in each area will be connected to nearby edge gateways through the network and managed by the edge gateways. Among them, there may also be a connection relationship between the device terminals. For example, the light bulbs, LED displays, sensors, charging piles and other devices in the smart light pole will be connected to the centralized controller.

[0037] The edge side refers to the edge gateway, which is an intermediate facility connecting...
