Self-adaptive intelligent gas stove safety monitoring system

Abstract

The invention discloses a self-adaptive intelligent gas stove safety monitoring system. The system comprises an MCU and a composite sensing module; the composite sensing module comprises a fixed detection module; the fixed detection module comprises a support (61) and a plurality of horizontal detection units arranged on the support, and each horizontal detection unit comprises an infrared detection sensor and an ultrasonic sensor; the horizontal detection unit points to a fire outlet of a gas stove and the upper part of the fire outlet; the ultrasonic sensor is used for detecting whether thefront is blocked or not; the infrared detection sensor is used for detecting the front temperature; and the MCU judges whether dry burning occurs or not according to the composite sensing module, wherein the dry burning judgment process comprises the steps that if an obstacle is detected, the temperature is within the preset range of 140-180 DEG C and lasts for T time, it is determined that dry burning occurs. The self-adaptive intelligent gas stove safety monitoring system is ingenious in conception, easy to implement, capable of effectively preventing dry burning of a pot body, high in sensitivity and high in safety.

Description

technical field [0001] The invention relates to an adaptive intelligent gas stove safety monitoring system. Background technique [0002] Existing monitoring devices for kitchens mostly use temperature sensors to detect indoor temperature, and infrared sensors to sense whether someone is in the kitchen. In addition, more advanced ones, such as the invention patent with publication number CN105758529A, disclose a non-contact based The safety monitoring device for temperature detection uses an infrared temperature sensor to detect the temperature of the pot body to determine whether dry burning occurs. Although this method is ingenious, it needs to manually align the probe to the bottom of the pot, which is cumbersome to use, especially for the elderly. In addition, whether the sensor is aligned will greatly affect the accuracy of the result. Therefore, this device still exists Unreliable and weakly adaptive problems. [0003] Therefore, it is necessary to design a safety mo...
