According to the present invention, owing to adopt the intelligent control technology method, can make vacuum cleaner differentiate the kind and the quality on ground automatically, control automatically according to ground and dust suction state, produce the most appropriate suction, improve dust suction operating efficiency and performance.
Description of drawings
Fig. 1 is the control method flow chart that is used for the control system of smart cleaner of the present invention;
The specific embodiment describes the preferred embodiments of the present invention in detail below in conjunction with accompanying drawing
Traditional vacuum cleaner is to judge floor type and the quality that needs cleaning by the self-dependent intuition of user, sets optimal suction with manual order again.Can imagine that differentiate ground with experience intuitively, manual operation setting suction is a loaded down with trivial details process again, because the user must constantly carry out manual operation according to the state on ground.
Smart cleaner can reasonably be inferred the kind and the state on ground according to pressure detecting result and current detecting result, and the user need not often observe ground, the error that the intuition of also having avoided varying with each individual is judged.Simultaneously, draw corresponding desirable suction with fuzzy reasoning, and control the duty of air-breathing motor according to ground and quality.Like this, just make entire work process overcome artificial error, reach higher dust collection efficiency.
As shown in Figure 1.With carpet wool length, floor kind and quality and dust suction amount is input quantity, i.e. condition; With the phase place is output quantity, i.e. result.The length of carpet wool is to ask for by changeing the brush motor current value; Floor kind and quality change by the pressure in the dust catcher operating process to be asked for; The dust suction amount is asked for by force value.Therefore, in the fuzzy reasoning of practical application, be to change with current value, pressure, pressure to infer the phase place that use as initial conditions.
Pressure detecting and ground discriminating step, pressure sensor are semiconductor pressure sensors, and it utilizes semi-conductor silicon chip when being stressed generation deformation resistance value to be changed and reflects pressure state.
Four resistance that are connected into bridge-type are arranged on the silicon chip, when producing deformation, the resistance of bridge resistor is changed owing to silicon chip, the electric bridge disequilibrium, at this moment the voltage change of Chan Shenging just changes corresponding to pressure.Therefore, sensor can detect atmospheric pressure and be added in poor between the pressure on the pressure introducing port.Sensor is arranged on the control circuit printed circuit board (PCB), therefore, pressure measurement place must be connected on the introducing port of sensor with pipe, and the pressure of at this moment measuring is this place's pressure and atmospheric difference.
In vacuum cleaner, pressure is meant the pressure between air-breathing motor front and the dirt catcher.Be in when slowly running at air-breathing motor, dust bag and filter are in clog-free state, the about 3000Pa of pressure at this moment; When air-breathing motor is in when running up, suction inlet is in the complete closed state, and pressure at this moment is approximately 2.5 * 10
4Therefore Pa produces negative pressure to atmospheric pressure.
Infer the ground quality with pressure, the amount of dust in the dust bag is estimated by surface pressure before measuring air-breathing motor, thus the replacing time of deduction dust bag.The suction inlet kiss the earth of brush holder also is inactive state, and the negative pressure during than a little higher than ground of suction inlet is big.So the amount of dust that shows when the suction inlet kiss the earth can produce certain deviation.But the suction inlet of brush holder moves forward and backward and will reduce this error.
Static and the absorption of the suction inlet of brush holder on the ground will build-up of pressure increases.On the contrary, if suction inlet moves forward and backward, at this moment, the reach process is in impaction state, after move past the Cheng Ze suction inlet and be in the state of peeling off, therefore, produce the variation of pressure.In addition, turned back to by the front in the process of back, there is mentioning of certain hour the front portion of suction inlet, and at this moment pressure can reach maximum.Learn by experiment: the pressure of timber floor is less, and the variation of the pressure in the dust suction process is roughly 0; The formed pressure ratio plank of frizzle type carpet is big, and pressure changes also slightly more greatly; It is big that the pressure ratio frizzle type carpet that pine tag type carpet produces is wanted, and its pressure changes greatly; It is big that the pressure ratio pine tag type carpet that the shearing-type carpet forms is wanted, but the pressure variation is less; With the pressure maximum that dirt is produced on the floor of mat, still, pressure changes and shearing shape carpet is similar to.
Current detecting and ground discriminating step are when inferring the classification on ground with this physical quantity of pressure, because of of a great variety being difficult to of carpet realizes differentiating accurately.Therefore, need and change the brush current of electric with pressure combines and can finish.Detecting changes brush current of electric employing current transformer.Changeing the brush motor is 0.2A at suction inlet state load electric current hour, and the electric current during motor rotation is 2.5A.The voltage that current transformer is responded to has only tens millivolts.Therefore, carry out full-wave rectification and amplification, send in the single-chip microcomputer to produce corresponding 0~5V DC voltage with operational amplifier.
Infer the ground quality with electric current, when various dissimilar carpets were carried out dust suction, the current characteristic of vacuum cleaner was different.Therefore, change the electric current of brush motor, just can infer the quality of carpet by detecting vacuum cleaner.
There is spike in the current waveform of pine tag type carpet.Static or when moving forward and backward, the current peak that changes the brush motor is all bigger at brush holder, special in the dust suction process in the past backward or from after conversion moment of moving forward can produce sharp-pointed peak value.This is because the wadding of wool of carpet is entangled in to change to brush, or hair is peeled off the load increase that Shi Douhui makes motor from brushing.
The current waveform of the undercoat carpet of shearing-type is fluctuation shape.It does not produce sharp-pointed peak value, but forms comparatively level and smooth crest and trough.Crest partly be brush holder when moving forward, the blanket hair is run into brush to be increased motor load and forms.Because the undercoat carpet can the circumvolution brush, so can not produce the spike waveform.Trough part then is when rearward mobile, does not alleviate and is produced owing to almost there is hair to run into load that the face of brushing makes motor.
The current waveform balance of the undercoat carpet of frizzle type is calm.Brush holder changes the variation that does not almost occur electric current in the brush motor when current detecting, and waveform is steady.This is because change the surface that brush just contacts carpet lightly, the few of variation of the load of motor.The electric current that is detected is handled, judged the kind and the quality of carpet by fuzzy reasoning.
