Kitchen environment security monitoring system based on Internet of Things and monitoring method of kitchen environment security monitoring system

Abstract

The invention discloses a kitchen environment security monitoring system based on Internet of Things and a monitoring method of the kitchen environment security monitoring system. The kitchen environment security monitoring system comprises a main controller, a combustible gas concentration sensor, a PM2.5 (Particulate Matter 2.5) concentration sensor, a gas valve closing device, a display screen,an electronic window opener, a buzzer and a GPRS (General Packet Radio Service) communication module, wherein the combustible gas concentration sensor and the PM2.5 concentration sensor are respectively connected with the main controller; the main controller is connected with the GPRS communication module; remote signal transmission can be carried out through the GPRS communication module; the display screen is connected with the main controller and is used for displaying PM2.5 concentration values and combustible gas concentration values; the buzzer is connected with the main controller andis used for giving buzzing alarms; and the main controller is connected with the gas valve closing device and the electronic window opener, and used for achieving control on a gas valve and a window.By adopting the system, concentrations of combustible gases and PM2.5 in a kitchen environment can be monitored, alarm signals can be transmitted once the concentrations exceed standards, the window can be opened, the gas valve can be closed, and thus life and property loss can be effectively avoided.

Description

Technical field [0001] The invention belongs to the technical field of kitchen environment safety, and specifically relates to a kitchen environment safety monitoring system based on the Internet of Things and a monitoring method thereof. Background technique [0002] PM2.5 is a killer that endangers human health. Due to the special environment in the kitchen, the cooking fume produced during cooking will contain a large amount of PM2.5 (that is, inhalable particles with a particle size less than or equal to 2.5 microns). [0003] Gas leakage refers to the accidental gas leakage from the pipeline into the air. At present, gas water heaters and kitchen stoves all need gas. It is easy to encounter gas leakage during use, such as gas leakage caused by extinguished open flames, aging pipes, or failure of kitchen stoves. Once gas leakage occurs, the space Users in a closed environment may be poisoned or cause an explosion, threatening their lives and property. [0004] With the developm...

AI Technical Summary

Problems solved by technology

At present, both gas water heaters and kitchen stoves need to use gas, and it is easy to encounter gas leakage during use, such as gas leakage caused by extinguished open flames, aging pipelines, or failure of kitchen stoves. Users in a closed environment will be poisoned or explode, threatening life and property

[0004] With the development of the Internet of Things technology, some monitors capable of monitoring gas leakage and PM2.5 have appeared on the market, but there is a lack of one that can simultaneously monitor the concentration of combustible gas and PM2.5 and has an alarm function. Comprehensive kitchen environment safety monitoring system with corresponding processing mechanism

[0005] In addition, there are currently some kitchen stoves that can detect leaks and automatically shut down on the market, but they are the switches of the closed stove itself, and the leak point is likely to be on the connecting hose between the gas pipeline and the kitchen stove (gas pipeline The connection between the hose and the gas pipeline and the connection between the hose and the kitchen stove is most likely to occur through a hose), therefore, in this case, even if the stove’s own switch is turned off, it will not play a role. The purpose of preventing gas leakage
