Cloud-edge cooperative linkage system suitable for smart Internet of Things system

Abstract

The invention discloses a cloud-edge cooperative linkage system suitable for a smart Internet of Things system, and the system comprises an uplink MQTT communication module which achieves message interaction between the cloud-edge cooperative linkage system and a platform side MQTT; a downlink communication module which achieves MQTT message interaction between the cloud-edge cooperative linkage system and an internal data center of an edge Internet of Things agent device; a message body mapping module which realizes information interaction with each APP in the edge Internet of Things proxy device through an MQTT protocol in the edge Internet of Things proxy device; and a management function module which realizes equipment access and registration functions of the edge Internet of Things proxy device to an Internet of Things management platform. According to the sstem, application management collaboration, service management collaboration, security policy collaboration and resource collaboration between the edge Internet of Things proxy device and the Internet of Things management platform can be realized.

Description

technical field [0001] The invention relates to a cloud-edge collaborative linkage system, in particular to a system suitable for linkage between an IoT management platform and an edge IoT agent in a smart IoT system. Background technique [0002] With the continuous advancement of the construction of the State Grid Corporation's smart IoT system, the construction of the IoT management platform by provincial companies is also becoming more and more perfect, and various original business data have gradually begun to be connected to the IoT management platform. As an edge-side device in the smart IoT system, the edge IoT proxy device on the one hand carries part of the computing functions under the platform, and on the other hand realizes the collection, analysis, and computing functions of data collected by its southbound sensing devices. It can shield the underlying network differences, break the vertical closed mode of the traditional Internet of Things, establish a "hub" f...

AI Technical Summary

Problems solved by technology

The above scheme only realizes the data interaction scheme between the functional modules inside the edge IoT agent device, and does not design the data interaction between the edge IoT agent device and the IoT management platform, nor does it involve application management collaboration and business management collaboration , security policy collaboration, and resource collaboration functions cannot accurately and efficiently complete cloud-side collaborative management and control
