Automatic gas alarm

Abstract

An automatic gas alarm is provided, which has a gas sensor probe and a microprocessor, and also includes a smoke sensor probe and a temperature sensor probe, the gas sensor probe, the smoke sensor probe and the temperature sensor probe are all connected to the microprocessor, and the microprocessor It is connected to the sound and light alarm device, and the microprocessor is also connected to the gas solenoid valve and exhaust fan through the driving device. The electrical signals of the gas sensor probe, smoke sensor probe and temperature sensor probe are detected and processed by the microprocessor and then transmitted to the sound and light alarm device. The alarm device automatically alarms, and the microprocessor outputs signals to the drive device to drive the gas solenoid valve and the exhaust fan to work. The present invention judges dangerous situations by detecting various air parameters, sends out alarm signals in time, and can automatically eliminate dangerous situations in time, effectively reduces the occurrence rate of dangerous situations, avoids further danger caused by improper human operation, and ensures personal and property safety.

Description

technical field [0001] The invention belongs to the technical field of alarms, in particular to an automatic gas alarm. Background technique [0002] The existing household and commercial gas alarm devices in the market simply detect the gas concentration after gas leakage and provide audible and visual alarm signals to remind operators of danger. Operators need to manually close the valve and ventilate to eliminate the danger. Under normal circumstances, the detection of gas concentration alone cannot judge the danger in a more timely and effective manner, delaying the alarm time, causing the danger to aggravate; at the same time, after the existing alarm alarms, personnel need to manually close the valve and ventilate. If the personnel do not operate properly, Will further stimulate dangerous situation, cause bigger personal and property safety accident. Therefore it is necessary to propose improvements. Contents of the invention [0003] The technical problem solved b...

Under normal circumstances, the detection of gas concentration alone cannot judge the danger in a more timely and effective manner, delaying the alarm time, causing the danger to aggravate; at the same time, after the existing alarm alarms, personnel need to manually close the valve and ventilate. If the personnel do not operate properly, It will further stimulate the dangerous situation and cause greater personal and property safety accidents.
