Block, automatic gas adjust valve module, and range hood module, speech recognition module, LCD MODULE and network communication module are equal
It is connect with single-chip microcontroller.
Single-chip microcontroller model selection be positive point atom stm32F407, the single-chip microcontroller have low-voltage and low-power dissipation, high-performance,
The advantages that strong interference immunity.In addition, single-chip microcontroller has been internally integrated timer, the I/O resource of ADC and abundance.
Sensor module: gas sensor is monitored indoor gas concentration, when gas sensor detects combustion gas
When density is exceeded in air, interrupt signal is sent to CPU, CPU generates control signal and gsm module is driven to send out to user mobile phone
Send gas leakage alarm signal, driving relay control loudspeaker automatic alarm and pushing function external electrical magnet valve, cutting combustion
Gas channel is also turned on external range hood power supply, makes its operation, when the combustion gas density in air is lower than setting value, gas
Body sensor is sent to CPU stops range hood working signal, and range hood stops working.Temperature sensor measurement temperature of boiler
When detecting dry pot phenomenon, interrupt signal is sent to CPU, and control signal is generated by CPU and drives external automatic alarm, relay
Device controls loudspeaker automatic alarm, and solenoid valve is pushed to cut off blast tube, stops gas-cooker and heats to the bottom of a pan.
Solenoid valve control module: the central processing unit for controlling modules is single-chip microcontroller, the control of the I/O output of single-chip microcontroller
Signal is 0 or 1, and control mode is simple and efficient, but there are security risks.That is I/O mouthfuls probably due to certain interference or internal breakdown
It causes to continue 0 or 1 signal of output, very likely occurs gas leakage problem in this way on gas-cooker.In driving circuit for electromagnetic valve
On be made that following adjustment.The both ends of one side solenoid valve are all controlled respectively, and the probability that two-way breaks down simultaneously is very low；
On the other hand, controlled on the way using square wave wherein, can not also be kept when there are I/O mouthfuls of failures so original frequency into
Row output, to avoid fault open solenoid valve.Solenoid-driven schematic diagram is as shown in Figure 2:
Flame detection modules: fire defector mainly passes through LM258 operational amplifier, and the signal of thermocouple is amplified 100
Times, single-chip microcontroller determines the flame combustion state of gas-cooker, using schematic diagram such as Fig. 3 institute by the voltage signal variation of detection CY1
Show:

Work.Its working principle diagram is as shown in Figure 6.When kitchen is cooked, oil suction while user opens gas-cooker control panel-switch
Whether smoke machine automatic work detects in gas-cooker after 15 seconds with the presence of flame, if existing without flame, voice broadcast exception information
And close fume-exhausting smoke machine；If there is flame, smoke extractor is in normal operating conditions.In addition, when sensor module detects electromagnetism
When valve is closed, smoke extractor work automatic shutdown after a certain period of time.
After opening gas-cooker control panel-switch, intelligent gas stove control system, which automaticly inspects each system of gas-cooker, is
No normal work.If detection is not over gas-cooker system enters idle protection state, while showing combustion gas over the display
Stove exception information simultaneously carries out voice broadcast, automatic shutdown after a period of time.If detection passes through, igniter is opened, and solenoid valve is opened,
Simultaneously detect flame whether normal combustion；If without normal combustion, into opening igniter and solenoid cycles, when timing is to 8S
Flame combustion is still abnormal, and igniter and solenoid valve is automatically closed, and into standby mode, display screen shows that exception information is gone forward side by side
Row voice broadcast, automatic shutdown after certain time.
After detecting flame normal combustion, igniter is closed, opens the reception to thermocouple signal.It is special when food in pot
It is not after soup food overflows, gas flame to be caused to extinguish, to the cold, thermo-electromotive force disappears thermocouple, makes the iron core of safety valve because of spring
Effect is closed, and causes gas supply to interrupt automatically, while intelligent gas stove control system enters standby mode, display screen is shown
Exception information simultaneously carries out voice broadcast.
After detecting that flame normal combustion, igniter are closed, voice prompting owner selects suitable gas-cooker operating mode,
After selecting suitable operating mode, intelligent gas stove control system can be connected to home network by WIFI module, lead to
It crosses Ethernet to enter in corresponding database, reads information relevant to recipe and culinary art, broadcast by voice system
Report；Or it can choose the voice program oneself liked.
When operating mode completes timing, voice broadcasting system prompt user related information simultaneously carries out subsequent work mould
Formula.When not having key or speech answering, into voice reminder cycle of states, after a certain period of time, Self-shut electromagnetic valve, intelligence is fired
Gas kitchen control system enters standby mode, and display screen shows exception information and records.When obtaining key or speech answering, to user
After having handled related work, automatically into subsequent work mode.When obtaining key shutdown and speech answering shutdown, gas-cooker
Solenoid valve is just closed, into standby mode.
