Description of drawings
Fig. 1 is a theory diagram of the present utility model;
Fig. 2 is the concrete circuit theory diagrams of implementing of this utility model.
The specific embodiment
As shown in Figure 1, comprise power supply, single-chip microcomputer, burning kitchen range, the electromagnetic valve that is used to control air inlet, infrared induction circuit, high-voltage pulse firing circuit, flame detection circuit, the input port of the delivery outlet of infrared induction circuit, high-voltage pulse firing circuit, the delivery outlet of flame detection circuit link to each other with the corresponding interface on the single-chip microcomputer, the high-voltage pulse outfan of high-voltage pulse firing circuit connects on the spray point that places burning kitchen range lighting-up tuyere, the control output end of single-chip microcomputer connects the control end of electromagnetic valve, and the gas outlet of electromagnetic valve is connected to the air inlet of burning kitchen range.When the infrared sensor induction zone in the close infrared induction circuit of hands, single-chip microcomputer is received the igniting request, sends the instruction unpack electromagnetic valve, and sends high tension spark at burning kitchen range top and light through mixed combustion gas; Flame detection circuit enters detected state thereupon, in case fray-out of flame, single-chip microcomputer exports control signal at once and cuts out electromagnetic valve.Install on the burning kitchen range and be used to regulate the knob of tolerance, realization manual adjustments flame size.This utility model also is provided for triggering the Single-chip Controlling foot switch and the wireless receiving circuit that is used to receive remote signal of igniting automatically in addition, foot switch is connected in relative trigger end on the single-chip microcomputer, wireless receiving circuit links to each other with remote signal input interface on the single-chip microcomputer, so also realize the automatic igniting of foot-operated control and realize remote control ignition, handled easily.
As shown in Figure 2, single-chip microcomputer U2 adopts the AVR family chip, and the infrared induction circuit comprises that model is that 8550 audion Q1, model are infrared receiving module U3, the light emitting diode D1 of AT138B; The high-voltage pulse firing circuit mainly comprises audion Q2, transformator T1, T2, controllable silicon D5.When living light that light emitting diode D1 sends with stick shift to infrared receiving module U3, this moment, the PB1 end output high level of single-chip microcomputer U2 made audion Q3, Q4 conducting, and electromagnetic valve gets electric work; The PB2 end triggering signal of single-chip microcomputer U2 makes the high-voltage pulse firing circuit produce vibration output high-voltage pulse and lights a fire.Flame detection circuit mainly comprises resistance R 9, R7, R8, capacitor C 5, flame sensing needle.
Concrete implementation in the single-chip microcomputer is, works as energized, and program enters initialization, start watchdog circuit, the state of flame detection pick off, if any fault then status indicator lamp " STATUS " send the indication of " dodge and stop 1 time for 3 times ", and enter the power down power save mode, wait watchdog circuit to reset.When starting watchdog circuit, program is carried out the processing of infrared signal, detects to have or not the infrared signal input.As there is not an input, enter the power down power save mode, if input (promptly have object at coverage near infrared sensor) is arranged, at this moment whether program detect foot switch again and step on, step on as nothing, the infra red treatment program begins counting (anti-interference time-delay counting), after having counted, enters ignition procedure, open electromagnetic valve, produce high-voltage pulse on burner, program is followed the flame detection transducing signal, as the success of lighting a fire, program enters hold mode, and detect foot switch again and whether be operated again, if step on, program is closed electromagnetic valve at once and is got back to original state and enters circulation next time.
