An internet of things cloud end data interaction system

摘要

The invention relates to an internet of things cloud end data interaction system. A Hall alarm sensor, a flow pressure sensor and a video camera arc installed on the upper surface of a liquid level displayer. Flow pressure information and video information are obtained in real time through the Hall alarm sensor, the flow pressure sensor and the video camera on the liquid level displayer. The alarm information of the highest liquid level and the alarm information of the lowest liquid level are collected through the Hall alarm sensor, all the information is synthesized through a digital signal synthesizer and divided into three routes, one route enters a data recorder to be automatically recorded, another route enters a 2.4G wireless comprehensive data transmission device and enters an internal control system, and the third route has access to a 3G network of an internet of things cloud end so that a remote internet of things can be observed and controlled in real time.
