Open state (in other words, after gas burning system is normal, can magnetic valve 106 described in hand-reset be opening state)；The display
Module 108, for showing the detected value of sensor assembly 103.
It should be noted that the main function of power module 102 is, by 220V Power converts into 24V, 5V, 3.3V, to electricity
Magnet valve, sensor assembly, control module, extinguishing device etc. provide power supply, and wherein 24V is that magnetic valve supplies with aerosol fire-extinguishing device
Electricity, 5V power for sensor, and 3.3V powers for control module.
In addition, main control module is mainly using MCU as core, including sensor Acquisition Circuit, display driver circuit, alarm electricity
Road, control relay circuit, keystroke interface circuit etc., mainly complete the functions such as signal acquisition, control, warning output.
In one example, it is described when the detected value of the sensor assembly 103 is more than or equal to predetermined threshold value, it is described
Control module 101 controls the magnetic valve 106 to turn off, and controls the warning device 104 to alarm, in addition to：The control mould

Skilled person will appreciate that when system detectio to pipe gas flows or leaks, system starts timing；When fixed
When the time arrive, then control module is disconnected magnetic valve by relay, cut off gas pipeline.When smoke detectors detect kitchen
During generation fire (flue gas concentration severe overweight), then control module starts aerosol fire-extinguishing device by relay, is put out a fire.
This control system utilizes the mechanism of pipeline " gas flow " detection, can not only monitor whether combustion gas leaks,
More importantly, additionally it is possible to which effective control combustion gas engagement time, using the time of setting, to opening fire, process carries out time control
System, time arrive, then automatically cut off gas pipeline.This control system also has flue gas inspection function simultaneously.
Firstly because during gas range is opened fire or during gas leakage, combustion gas becomes " to flow " from " non-current ", control
Mainboard processed can detect the change of gas flow by Hall flow sensor, and at this moment, control system starts timing (during timing
Between can be controlled by knob), when timing arrives, then control mainboard closes magnetic valve, and gas pipeline is closed.
On the other hand, by smoke detectors, it can detect and be happened suddenly caused by unexpected (such as short circuit reason)
Catch fire, when this occurs, break magnetic valve immediately, while start aerosol fire-extinguishing.System reaches to domestic gas
The function of " examine, control, going out " integration.
A kind of possible structure of domestic gas control system in the utility model embodiment is illustrated below.
The flow of combustion gas is mainly changed into electric impulse signal and send MCU by Hall flow sensor, and MCU passes through pulse signal
Judge that combustion gas has been switched on or in leak condition.Hall flow sensor operating voltage DC3.5~24V, system use+
5V powers, and output high level is+5V, and low level is about 0V.Smoke detectors use MP503 sensors, this sensor in Fig. 1
The gases such as flue gas, alcohol, formaldehyde can be detected, based on flue gas, mainly for detection of the fire accident in kitchen, this accident can
Can be the fire accident of gas leakage or the fire accident of other factors, now control module sends police by smoke alarm
Report and according to the grade of flue gas concentration, handled accordingly, when flue gas grade reaches severe overweight, start extinguishing device.
Now system will also combine current gas flow and change, if gas pipeline has gas flowing, while electromagnetism valve events are cut off
Gas pipeline.
