Title:
REAL-TIME DETECTION APPARATUS FOR REFRIGERATOR STATE, AND REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2019/042408
Kind Code:
A1
Abstract:
Disclosed is a real-time detection apparatus for a refrigerator state, comprising a Hall sensor (1), an MCU (2), an NB-IOT module (3), an antenna module (4) and a USIM card (5), wherein the Hall sensor (1), the MCU (2), the NB-IOT module (3) and the antenna module (4) are successively electrically connected, the USIM card (5) is electrically connected to the NB-IOT module (3), and the Hall sensor (1) is arranged close to a refrigerator door of a refrigerator and is used for detecting whether the refrigerator door of the refrigerator is open. The number of times the refrigerator door is opened can be automatically counted, thereby saving on labor costs, and the statistical data can be uploaded in real time, thereby overcoming a spatial limitation. The apparatus further has a unique identity to avoid disorder occurring in the statistical data. Further disclosed is a refrigerator having the function of counting the number of times the refrigerator door is opened.
