Description

Based on the multifunction gas stove of the singlechip technology pass ignition system of opening fire automatically

Affiliated technical field:

The utility model relates to a kind of automatically controlled intelligent gas valve based on 51 singlechip technologies, especially realizes the button igniting, regularly closes the intelligent gas-burning stove of fire.

Background technology:

Gas-cooker in the market mostly is with rotary switch and regulates firepower, do not have regularly functions such as Guan Huo.Use for household.Waste time and energy and rapid wear, occur accident easily, might open fire by unable twisting turn-knob for the elderly or patient.Cause great inconvenience.

Summary of the invention:

In order to overcome old type gas-cooker effort and unsettled firing system and other some shortcomings.The utility model provides a kind of flame-out function of touch-tone additional timing of singlechip technology control of utilizing can increase the intelligent gas-burning stove of additional function by the upgrading Single Chip Microcomputer (SCM) program with other.

1. the utility model solves the technical scheme that its technical matters adopts and is: be connected by lead with two 7 sections charactrons by five electronic switches of a 80C51 single-chip microcomputer and an electromagnetic pulse valve, wherein, five electronic switches are connected with 80C51 single-chip microcomputer input signal end; An electromagnetic pulse valve is connected with the output signal end of 80C51 with two 7 sections charactrons.To the 80C51 mcu programming, this program is deposited in the 80C51 single-chip microcomputer to realize following 3 purposes:

1. single-chip microcomputer is controlled the electric impulse signal that electromagnetic impulse valve is opened by one of I/O (F) output behind electric signal of key 1 input, the electric impulse signal of closing by a control of I/O (H) output electromagnetic impulse valve behind electric signal of key 5 inputs, and make the zero clearing of countdown the number of minutes.

2. make the timer function of chip microcontroller count-down.And set count-down by key 2 and add the number of minutes, key 3 is set count-down and is subtracted the number of minutes, key 4 is controlled the electric impulse signal that electromagnetic impulse valve is opened for the beginning of timing mode and by one of I/O (G) output, and the electric impulse signal that electromagnetic impulse valve is closed is controlled in one of output automatically when count-down finishes.I/O (A) in the single-chip processor i/o input end wherein, I/O (B), I/O (C), I/O (D), I/O (E) connects

button

1,2,3,4,5 respectively.I/O in the single-chip processor i/o output terminal (F), I/O (G) links to each other with the opening signal input end of electric pulse electromagnetism gas raft.I/O (H) links to each other with the opening signal output terminal of electric pulse electromagnetism gas raft.All the other I/O mouths link to each other with 27 sections charactrons.

3. when key 2, key 3 single-chip microcomputer when regulating countdown the number of minutes is exported corresponding signal and is used to control 27 charactrons, shows the time of countdown.

The utility model works in the non-pattern of clocking when beginning: the operator presses 1 on key by electric impulse signal of single-chip processor i/o (F) end output, solenoid valve receives to be opened valve behind this signal combustion gas is flowed out to reach the igniting purpose, when the operator presses 5 on key by another electric impulse signal of single-chip processor i/o (H) end output, make closed electromagnetic valve to reach the purpose of closing fire.

The utility model works in the pattern of clocking when beginning: at first by key 2, key 3 configure the count-down time (the number of minutes) then the operator press key 4 beginning count-downs and by electric impulse signal of I/O (G) end output, solenoid valve receives to be opened valve behind this signal and makes combustion gas flow out igniting.Single-chip microcomputer is exported another electric impulse signal automatically after count-down finishes, make closed electromagnetic valve reaching the purpose of closing fire or directly to press key 5, and the replacement count-down is 0 to make closed electromagnetic valve to reach the purpose of closing fire thus by single-chip processor i/o (H) end output closed electromagnetic valve electric impulse signal.

The beneficial effects of the utility model are can realize the key switch of gas-cooker and can freely set the time auto extinguishing that closes fire.Greatly facilitating family uses.And because single-chip microcomputer has very big extensibility, (it is flame-out for example can to increase thermometric to reach the purpose that increases other subsidiary functions for program that can also be by the upgrading single-chip microcomputer in the use in future, the contact witch fire) and the ripe software language of singlechip technology easy-to-understand, (retail price is several units of Renminbi only) with low cost, extensibility is strong, and the energy steady operation is in rugged surroundings.So these utility model market outlook are fabulous.
