Smart egg rack and application thereof

Abstract

The invention provides a smart egg rack and application thereof. The smart egg rack comprises a bottom plate and a dragging egg tray. The dragging egg tray is provided with a plurality of egg placinggrids; an ultrasonic ranging sensor for detecting whether an egg is placed in the grid is arranged at the bottom of each egg placing grid. A circuit board is installed inside the bottom plate and includes an MCU, an NB-IoT transceiver module, a power module and a photosensitive diode; a signal output terminal of each ultrasonic ranging sensor is connected with an STM32L431RCT6; the photosensitivediode is used for sensing the light situation in a refrigerator; and the power module is connected with the MCU by the photosensitive diode. When the photosensitive diode is in conduction and the power module provides power for the photosensitive diode, the system starts working. Since the egg rack employs the NB-IoT wireless communication mode, effective monitoring of the freshness of the eggs inthe refrigerator, the number of eggs, and the time of use of the refrigerator is completed simultaneously.

Description

technical field [0001] The invention belongs to the field of electronic information technology and smart home technology, and in particular relates to a smart egg rack and its application. Background technique [0002] With the development of mobile Internet and Internet of Things technology, people's requirements for intelligent life are gradually increasing, but the vast majority of people do not have the urgent need to replace smart home appliances, so we provide a method to intelligentize traditional home appliances. In this embodiment, a brand-new intelligent egg rack is designed to make the traditional refrigerator intelligent. [0003] Eggs are an indispensable ingredient in every family, so it is particularly important to ensure the freshness of eggs in the refrigerator. In order to facilitate people to know the freshness of eggs, or to choose eggs with different freshness when cooking , At the same time, it solves the situation that people often ignore the number o...
