Method for carrying out safety monitoring and early warning on kitchen work environment and system

Abstract

The present invention relates to a method for carrying out safety monitoring and early warning on a kitchen working environment and a system. The method comprises the following steps that gas stove integrated operating state data is collected and converted into a gas stove integrated operating state logic signal and is transmitted to a central CPU processing module, the central CPU processing module carries out abnormal condition judgment on the gas stove integrated operating state logic signal according to a predetermined gas stove integrated work state logic representation, if an abnormal condition is judged, the duration of the abnormal condition is counted, the central CPU processing module judges whether the duration of the abnormal condition reaches a predetermined timed interval, if so, the alarming is carried out according to an alarm level and the alarm duration is counted, the central CPU processing module judges whether the abnormal condition exists or not when the alarm duration reaches a predetermined alarm time duration, and if the abnormal condition still exists, emergency measures are implemented. According to the method and the system, the intelligent monitoring, classification process and multi-level warning of the kitchen working environment can be realized, and the safety performance is high.

Description

technical field [0001] The invention relates to the field of kitchen safety monitoring and early warning, in particular to a method and system for safety monitoring and early warning of a kitchen working environment. Background technique [0002] As food safety issues become increasingly prominent, people tend to cook at home more and more. The kitchen is a place with high frequency of use, and most families use gas stoves to boil water, cook, and stir-fry. The kitchen naturally becomes a home. The most dangerous place in the environment, especially the gas stove, for example, [Scenario 1]: During the cooking process, soup may overflow to extinguish the flame, causing gas leakage. If it is not discovered in time and effective measures are not taken, it is easy to cause gas Poisoning or an explosion when encountering an open flame; [Scenario 2]: People (especially the elderly) often leave the kitchen to do other things when cooking. After a long time, they may forget that the...

Problems solved by technology

Although this type of monitoring and alarm technology shortens the detection time, it cannot be reminded and alarmed before the accident occurs in [Scenario 2] or similar situations, so as to eliminate the hidden dangers that may cause fire accidents as soon as possible.

The root cause of the defect in the above-mentioned monitoring and alarm technology and system is the limitation of the definition of the working state of the gas stove, that is, only the state of the gas stove itself is considered, and the user and operator of the gas stove are ignored. Therefore, it is impossible to detect and judge the abnormal state (such as no one is around when the gas stove is burning) in the operation of the gas stove, so that the potential or possible danger cannot be predicted and reminded

[0004] Also have the detection to user (people) in the prior art, but still there are some defectives: (1) what adopt to the detection of user's people is the human body induction pyro-infrared sensor, mainly has induction to moving object, if people stand If you don’t move or accidentally fall down, the detection result will be inaccurate; (2) the alarm level is relatively single, and because it is realized by a variable resistor, the adjustable range has great limitations; (3) the ambient temperature reaches 45 The temperature sensor is used to judge the working state of the gas stove is not accurate enough. After the pot is heated, even if the temperature of the fire is turned off (higher than 45 degrees), it will continue to be high for a period of time; (4) The timing is determined by the capacity of the electrolytic capacitor And the resistance value of the variable resistor is determined. Once the component is selected, it cannot be changed; (5) The realization of the entire device is realized through circuit hardware, lacking software support, so it is difficult to identify various abnormal conditions in the kitchen. Different timing intervals are used in different situations, and the refinement of the warning level and the diversification of the alarm methods are not competent
