Intelligent anti-dry-burning alarm system for gas stove

Abstract

The invention discloses an intelligent anti-dry-burning alarm system for a gas stove. The intelligent anti-dry-burning alarm system for the gas stove comprises a temperature sensor arranged above the gas stove, the temperature sensor is used for measuring and collecting temperature data, an A / D converter is electrically connected with the temperature sensor through an amplifier and is used for amplifying the temperature data and carrying out analog-digital conversion, an input end of a single-chip microcomputer is electrically connected with the A / D converter and is used for transmitting the temperature data to the single-chip microcomputer, and an output end of the single-chip microcomputer is electrically connected with a fuel gas cut-off device used for cutting off the fuel gas and an acousto-optic alarm device used for providing sound and lamplight for giving an alarm respectively. According to the intelligent anti-dry-burning alarm system for the gas stove, the temperature sensor is arranged to sense whether the temperature of water changes in the container, the temperature changes are fed back to the single-chip microcomputer, the single-chip microcomputer controls an alarm device and an electromagnetic valve through the voltage change fed back, and an automatic alarm is given and the gas stove is closed when the water is burned dry.

Description

Technical field [0001] The invention belongs to the technical field of smart homes, and specifically relates to an intelligent anti-burning alarm system for a gas stove. Background technique [0002] Studies have shown that in the past 15 years, the number of people living alone worldwide has increased dramatically, from 153 million in 1996 to 277 million in 2011, an increase of 55% in 15 years.
