Embodiment Construction

[0026] The working principle of a home automatic alarm and exhaust system of the present invention is that the sensor converts the gas concentration into an analog voltage signal, and the millivolt-level electrical signal is sent to a low-pass filter through the first transmitter, and filtered out by the low-pass filter. Interference signal, the amplifier amplifies the signal and sends it to the A / D converter, transforms it into a digital signal and sends it to the controller for data analysis. When the concentration of gas in the air reaches the first set value, it will output a digital value, which is passed through D The / A converter is respectively sent to the second transmitter, the driver and the third transmitter. The second transmitter drives the solenoid valve execution unit to close the gas pipeline to reduce the gas transmission. The driver drives the relay to open the exhaust device. Exhaust the gas to reduce the indoor carbon monoxide content. When the carbon monox...

Abstract

The invention discloses a household automatic alarm and exhaust system comprising a gas concentration detecting module, a display screen, a power supply, a controller, an alarm module, and a processing module. The gas concentration detecting module comprises a sensor, a first transmitter, a filter, and an A / D converter. The processing module is connected with the controller through a D / A converter and comprises a first processing module, a second processing module, and a third processing module. The second processing module comprises a driver, a relay, and an exhaust device. The third processing module comprises a third transmitter and an electric appliance equipment execution unit. The household automatic alarm and exhaust system is simple in structure and good in practicality, enables a user to obtain gas leakage information by means of the alarm module and enables a security room to locate gas leakage as early as possible. The processing module may close a gas channel. Gas can be exhausted by the automatic speed regulation exhaust device. The electric appliance equipment execution unit disconnects the circuits of electric appliances in order to ensure personal and property safety.

Description

technical field [0001] The invention relates to a home automatic alarm and exhaust system. Background technique [0002] With the development of the economy, people pay more and more attention to the improvement of the quality of life and the improvement of the living environment. The entry of liquefied petroleum gas and gas into the family has brought convenience to people and improved the environment of the city, but it has also brought people Potential hazards, of which carbon monoxide is the most important source of danger. [0003] Carbon monoxide is a colorless and odorless gas. Because it has a high affinity with hemoglobin in the human body, when it is absorbed by the human body, it will compete for oxygen in the blood in the body to form carbon monoxide hemoglobin, which will make the arterial wall hypoxic, edema, and hinder The blood flow is normal, causing people to experience tiredness, shortness of breath, nausea and other adverse symptoms. At the same time, c...
