Detailed Description
In order to facilitate the understanding and implementation of the present invention for those skilled in the art, the technical solutions of the present invention will now be further described with reference to the accompanying drawings and specific embodiments.
Integrated cooking utensils intelligence control system include solenoid valve, plug valve, step motor, thermocouple, display screen, singlechip, impulse ignition ware, ignition controller, solenoid valve and plug valve install on the gas pipeline, the thermocouple is installed in the kitchen range position with impulse ignition ware side by side, the singlechip output is connected with ignition controller input, ignition controller output is connected with thermocouple and impulse ignition ware, the singlechip output is connected with solenoid valve and step motor control end, the step motor pivot is connected with the plug valve, the display screen is connected with the singlechip.
The control system further comprises a stepping motor drive circuit and an electromagnetic valve drive circuit, wherein the output end of the single chip microcomputer is connected with the stepping motor drive circuit and the input end of the electromagnetic valve drive circuit, the output end of the stepping motor drive circuit is connected with the stepping motor, and the output end of the electromagnetic valve drive circuit is connected with the electromagnetic valve.
The control system also comprises a flameout detection circuit, a pot temperature detection circuit and a signal conditioning circuit, wherein the flameout detection circuit and the pot temperature detection circuit are connected with the input end of the single chip microcomputer through the signal conditioning circuit.
The utility model discloses a still be provided with capacitanc response button, the output and the singlechip of capacitanc response button are connected for each item function that the required demonstration is gone up to the setting display screen.
The utility model discloses a thermocouple is as flame temperature sensor as shown in fig. 2, and vin is thermocouple voltage signal input, and the input is the negative voltage, so added the adder circuit. D1 is a 1.2V precision voltage-stabilizing tube, and a 50mV point is generated at the point A through R2R 3 partial pressure. When the temperature on the thermocouple changes, the vin terminal voltage changes, the voltage of the operational amplifier input end also changes, the signal is input to the input port PIB5 of the A/D converter of the single chip microcomputer after passing through the method, and the single chip microcomputer judges whether the ignition is successful or not by checking the new change and whether the ignition is intentionally generated or not.
The electromagnetic valve is preferably a 12V single coil power supply structure, and the attracting current is 0.1A. In order to increase the working example sentence of the stepping motor and reduce the working current of the stepping motor, a 12V four-phase 8-beat control stepping motor is also selected, and a singlechip generates positive and reverse rotation pulses. Because the solenoid valve and the stepping motor work in a larger single-pass mode, and the I/O port of the singlechip cannot be directly driven, a first-stage driving circuit needs to be added for the purpose, the driving chip selects ULN2003, and the driving circuit of the stepping motor without the driving current is larger than 500mA., as shown in figure 3.
The ignition mode adopts the traditional 12KV high-voltage pulse, the high-voltage ignition device consists of an oscillating circuit, a booster circuit and a discharge electrode, the circuit is shown in figure 4, when the Pluse end is input with high level during ignition, at the moment, Q2 is conducted, the ignition circuit starts to work, after the high-frequency oscillating circuit is boosted for the first time through a booster circuit transformer T1, a pulse signal with the amplitude of about 60V is generated on the secondary side of T1, and after the pulse signal is rectified by a fast recovery diode, the stable direct-current voltage is obtained. This dc voltage charges the capacitor C2 through resistor R2 while storing energy on the large capacitor C3. When the voltage on the C2 rises to about 30-35V, the bidirectional diode is conducted, the Silicon Controlled Rectifier (SCR) is started to conduct, the energy on the C3 releases energy to the primary coil of the secondary step-up transformer T2 through the bidirectional Silicon Controlled Rectifier (SCR), so that high voltage of more than 12KV is generated on the secondary coil of the T2, and the high voltage can break down air with a certain thickness, so that high-voltage pulse ignition is completed. Capacitor C3 recharges after discharge, thereby forming a series of sustained discharge ignitions.
