Abstract
The invention discloses a full-automatic washing machine high precision fuzzy control circuit and a method thereof. The circuit is composed of a single chip microcomputer IC1, an optical coupler IC2 and a motor M, the motor generates back electromotive force upon sudden failure of the motor during operation, the back electromotive force forms a pulse signal through the optical coupler and a processing circuit, the pulse signal is input to an interruption input end of the single chip microcomputer, one interruption is generated every time one pulse is input, the number of the pulses can be recorded according to the interruption times, namely the number of the pulses formed by the back electromotive force differs based on the different clothes put in, the more the clothes is put in, the small the number of the pulses is, and on the contrary, the number of the pulses is large, therefore, the quantity of the clothes can be judged via a software program so that the clothes can be washed at proper water level. According to the invention, the clothes can be washed by precisely selecting proper water level, thereby saving electric energy and water resource, realizing the full-automatic washing machine high precision fuzzy control and meeting the demands of customers.
Description
Technical field
The present invention relates to a kind of automatic washing machine Precision Fuzzy control circuit and method thereof.
Background technology
Automatic washing machine fuzzy control function be what of putting clothing according to the user judge automatically selection water level, fuzzy control principle be according to the size of motor inverse electromotive force judge clothing what so that select water level.The factor that influences the motor inverse electromotive force is a lot, and the state and the belt tension of each material such as motor, clutch coupling, belt, belt pulley, impeller all have very big influence to fuzzy control.Because the discreteness of each link is too big, fuzzy control Fuzzy Control of Washing Machines precision in the market is not ideal.
When motor sudden power in the running, motor can produce inverse electromotive force, and inverse electromotive force forms the interrupting input end that pulse signal is input to single-chip microcomputer through optocoupler and treatment circuit, and pulse of every input will produce an interruption.According to the number of times that interrupts, number that can recording impulse.According to the difference of putting into clothing, the formed pulse number of inverse electromotive force is different.Clothing is many more, and pulse is few more, otherwise many more.Therefore can judge what of clothing through software program, thereby can select suitable water level washing clothes.
But the factor that influences the motor inverse electromotive force is a lot, and the state and the belt tension of each material such as motor, clutch coupling, belt, belt pulley, impeller all have very big influence to the motor inverse electromotive force.Because the discreteness of each link is too big, causes the state of every machine inconsistent, the different machine of clothing of putting into as much but produces the different pulse number, also just can't select suitable water level.
