Kitchen fire alarm system and method for human body detection in front of cooking bench

Abstract

The invention discloses a kitchen fire alarm system and method for human body detection in front of a cooking bench. The system comprises a flame detection module, an analog-to-digital conversion module, a data transmission module, a main control module, a combustible gas detection module, a GSM communication module, a human body detection module, a temperature detection module and a distance measurement module. The method comprises the steps that the main control module calculates a combustible gas concentration value, a flame concentration value and a temperature value and compares the values with corresponding alarm thresholds; when any numerical value of the combustible gas concentration, the temperature and the flame concentration is detected to exceed the preset alarm thresholds, thehuman body detection module detects infrared rays emitted by a human body in front of a cooking bench, the distance measurement module measures the distance between the head of the human body in front of the cooking bench and the alarm system, and the main control module calculates the height of the human body in front of the cooking bench and selects whether to send alarm information or not. Before the kitchen fire alarm information is sent, the human body in front of the cooking bench is detected, and the practicability of the kitchen fire alarm system is improved.

Description

technical field [0001] The present invention relates to the technical field of physics, and further relates to a kitchen fire alarm system and method for human body detection in front of a stove in the kitchen safety alarm technical field. The invention can be used in the kitchen environment, through the detection of the temperature in the kitchen, the concentration of combustible gas and the people in front of the stove, so as to realize the comprehensive inspection of the fire danger in the kitchen. Background technique [0002] With the continuous innovation of technology, single-chip microcomputer has been deeply applied to various fields of industrial and agricultural production and people's daily life applications. Because it has complete functions like computer systems, but its volume and cost are far smaller than computers, it is widely used in various fields. in an electronic system. Likewise, the field of alarm technology is inseparable from its work. The kitchen...
