Problems solved by technology

When a communication failure occurs between the edge gateway and the platform, the gateway cannot upload the perception layer data to the platform, resulting in the loss of platform data, which in turn affects related application functions
For example, the lack of central air-conditioning operation data will affect the formulation of air-conditioning group control strategies; the lack of energy consumption monitoring data will affect the accuracy of energy consumption prediction

Embodiment Construction

[0057] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0058] refer to figure 1 , is a schematic flowchart of an alternative embodiment of the data caching method of the IoT edge gateway 20 provided by the present invention.

[0059] Specifically, such as figure 1 As shown, the Internet of Things edge gateway 20 data caching method comprises the following steps:

[0060] Step S101 , the edge gateway 20 judges whether the communication status with the IoT platform 10 is normal.

[0061] In some embodiments, the edge gateway 20 judging whether the communication status with the IoT platform 10 is normal includes: the edge gateway 20 periodically sends a heartbeat signal to the IoT platform 10; the edge gateway 20 judges whether a response message from the IoT platform 10 is ...

Abstract

The invention relates to an Internet of Things edge gateway data caching method and device. The method comprises the steps that an edge gateway judges whether the communication state with an Internet of Things platform is normal or not; if yes, the edge gateway obtains sensing layer data and sends the sensing layer data to the Internet of Things platform; if not, the edge gateway obtains sensing layer data and a cache triggering rule of the sensing layer data; and the edge gateway caches the sensing layer data according to the cache triggering rule. According to the invention, data uploading or caching can be carried out based on the communication state with the Internet of Things platform, the problem of platform data missing caused by communication faults of the edge gateway and the Internet of Things platform is effectively solved, the data integrity is ensured, and the problem that subsequent control strategies are affected or the prediction precision is poor due to data missing is avoided.

Description

technical field [0001] The present invention relates to the technical field of data caching, and more specifically, to a data caching method and device for an edge gateway of the Internet of Things. Background technique [0002] In the fields of smart buildings, smart parks, and smart hospitals, the Internet of Things generally consists of an Internet of Things platform, an edge gateway, and a perception layer (intelligent subsystem). The edge gateway is located between the IoT platform and the perception layer, and is responsible for uploading the data of the perception layer to the platform and sending the data of the platform to the perception layer at the same time. When a communication failure occurs between the edge gateway and the platform, the gateway cannot upload the perception layer data to the platform, resulting in the loss of platform data, which in turn affects related application functions. For example, the lack of central air-conditioning operation data wil...
