Description
Technical field
The utility model relates to a kind of lampblack absorber intelligent controlling device.
Background technology
Traditional oils fume purifying apparatus on market adopts machinery to adjust wind and nothing " suggestion gear " mostly; according to sense organ, user can only judge that oil smoke amount size carries out gear shift; often there will be gear and set irrational problem; gear setting is too low causes fume purifying poor effect; the too high waste causing electric energy of gear setting; and automatic cooking fumes purifier is due to the existence of automaton, cause its price relatively costly.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides that a kind of structure is simple, fume purifying is effective and can save the lampblack absorber intelligent controlling device of electric energy.
The technical scheme that the utility model solves the problem is: a kind of lampblack absorber intelligent controlling device, comprise oil smoke sensor, signal conditioning circuit, A/D change-over circuit, CPU, display, gear key, described oil smoke sensor, signal conditioning circuit, A/D change-over circuit, CPU is connected in series successively, oil smoke sensor gathers oil smoke concentration signal and the signal collected is sent into signal conditioning circuit, oil smoke concentration signal is carried out shaping by signal conditioning circuit, A/D change-over circuit is sent into after amplifying, the analog signal that signal conditioning circuit exports is converted to data signal and sends into CPU by A/D change-over circuit, CPU respectively with display, gear key is connected, CPU exports corresponding result according to the signal of input and shows to display screen.
Above-mentioned lampblack absorber intelligent controlling device also comprises memory, and described memory is connected with CPU.
In above-mentioned lampblack absorber intelligent controlling device, described oil smoke sensor adopts TGS2600 oil smoke sensor.
In above-mentioned lampblack absorber intelligent controlling device, described A/D change-over circuit master chip adopts ADC0809.
The beneficial effects of the utility model are: oil smoke sensor gathers oil smoke concentration signal and the signal collected is sent into signal conditioning circuit, oil smoke concentration signal is carried out shaping by signal conditioning circuit, be converted to data signal through A/D change-over circuit again after amplification and send into CPU, CPU exports corresponding result according to the signal of input and shows to display screen, display screen can detect oil smoke amount size by real-time display system, and suggestion gear is presented on liquid crystal display, user can according to actual needs with display gear adjusting knob, thus the situation of the waste of energy avoided gear adjustment unreasonable and cause or oil smoke process insufficient strength.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, the utility model comprises oil smoke sensor, signal conditioning circuit, A/D change-over circuit, CPU, display, gear key and memory, oil smoke sensor adopts TGS2600 oil smoke sensor, A/D change-over circuit master chip adopts ADC0809, CPU master chip is AT89C52, described oil smoke sensor, signal conditioning circuit, A/D change-over circuit, CPU is connected in series successively, CPU respectively with display, gear key, memory is connected, oil smoke sensor gathers oil smoke concentration signal and the signal collected is sent into signal conditioning circuit, oil smoke concentration signal is carried out shaping by signal conditioning circuit, be converted to data signal through A/D change-over circuit again after amplification and send into CPU, the oil smoke concentration of actual measurement and suggestion gear show at display screen according to the signal of input by CPU, user can determine the gear of gear key according to display.
The gear one that oil smoke is corresponding has three, oil smoke concentration is divided into three sections, and the line of demarcation between every section is threshold concentration n
aand n
b, as oil smoke concentration n ∈ (0, n
a) time show a gear, as oil smoke concentration n ∈ (n
, a, n
, b) time show two gears, n>n
, btime show three gears.In addition, during culinary art the size of oil smoke amount and cooking method, oil temperature, stove size etc. closely related, the size variation trend of oil smoke amount is irregular to be followed.When oil smoke amount is at the threshold value oil smoke amount n of setting
a, n
bnear when having a small interference, suggestion gear can be beated back and forth, brings inconvenience.For head it off can adopt way conventional in engineering, namely leave certain nargin Δ at Near Threshold.When oil smoke amount is in the upper and lower minor fluctuations of threshold value, only have when oil smoke amount could be shifted gears when the excursion of Near Threshold exceedes nargin Δ.Specifically, if n
a, n
bcorresponding nargin is respectively Δ
a, Δ
b, when system recommendations adjust a gear, oil smoke concentration n>n
a+ Δ
ainstantaneously, the suggestion gear on display screen will jump to two gears, with when should advise that gear is two gear, and oil smoke concentration n>n
b+ Δ
binstantaneously, advise that gear can jump to three gears; And when advising that gear is three gear, oil smoke concentration n<n
b-Δ
binstantaneously, suggestion gear just can jump to two gears, and the rest may be inferred.
