Title:
APPARATUS AND METHOD FOR AUTOMATICALLY MONITORING HEAT SOURCE IN HOME KITCHEN
Document Type and Number:
WIPO Patent Application WO/2019/080341
Kind Code:
A1
Abstract:
An apparatus and method for automatically monitoring a heat source in a home kitchen. The apparatus comprises: a controller (7), and a stepping electric motor control circuit, an infrared detector (1), a stepping electric motor 0° position recognition circuit, a status indicator light (10), a button (9) and a voice circuit, which are connected to the controller (7), wherein the stepping electric motor control circuit is connected to a stepping electric motor (5); and the infrared detector (1) comprises a driving circuit, a dual-element pyroelectric infrared sensor (24), a filter amplifier, a gate screen execution mechanism, and a Fresnel lens (13). The method comprises: by means of data analysis of two states, i.e. human body monitoring and heat source scanning, automatically recognizing an enabled state of a fixed heat source when there is no person in a kitchen, automatically determining a voice playing period according to the radiation intensity of the fixed heat source, and automatically playing voice alarm information. A fixed heat source in a kitchen can be effectively monitored, and intelligent home control over automatically recognizing a situation in which there is a person in a room and a situation in which there is no person in a room can be achieved.
