Kitchen safety detection system employing digital logic circuit

Abstract

The invention discloses a kitchen safety detection system employing a digital logic circuit, and the system comprises a controller, a gas concentration sensor, a smoke sensor and an alarm, wherein the gas concentration sensor, the smoke sensor and the alarm are respectively connected with the controller. The gas concentration sensor and the smoke sensor respectively detect the gas concentration and smoke concentration of a kitchen and transmit the detection data to the controller. The controller judges whether to start the alarm or not according to the data. The system can achieve the effective protection and alarm against the kitchen fire, and is higher in reliability.

Description

technical field [0001] The invention belongs to the technical field of detection, and in particular relates to a detection system for improving kitchen use safety. Background technique [0002] With the food problem becoming more and more serious, many people choose to cook at home. The kitchen is a place that people often use, and because the kitchen uses gas and open flames frequently, it has become the most fire-prone place in the family. Considering that there are many kinds of products for fire prevention, such as Chinese patent application number 201320338550.5, titled "a kitchen air quality detection and control system" by using gas sensors to detect the concentration of flammable gases and toxic gases in the air , and judge whether to ventilate; another example is Chinese Patent Application No. 201320004363.3, titled "a kitchen door with a temperature detector and an alarm". When a certain temperature is reached, an alarm is triggered to remind people to pay attenti...

Problems solved by technology

[0003] After careful analysis, it is not difficult to see that the above two applications cannot provide comprehensive protection in case of fire. For the first application, even if the concentration of flammable gas in the air is small, if there is an open flame, etc., it may cause a fire. At this time, the system cannot realize good monitoring; for the second application, when using gas for cooking, the temperature of the kitchen will increase, especially in the hot summer, when the ventilation is not smooth The temperature in the kitchen is even higher, so relying solely on the temperature to judge whether a fire has occurred can easily lead to false alarms

[0004] Through the above analysis, the existing kitchen safety detection system cannot achieve the desired effect well and needs to be improved
