Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.Wherein, accompanying drawing only for exemplary illustration, expression be only schematic diagram, but not pictorial diagram, can not be interpreted as the restriction to this patent; In order to embodiment of the present utility model is described better, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; For a person skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.
embodiment 1
The present embodiment provides a kind of Intellignet simple sound control electric fan, as shown in Figure 1 and 2, comprise electric fan main body 1, support 2 and plug 3, described electric fan main body is provided with acoustical-electrical transducer 11, acoustical-electrical transducer 11 is connected successively with single-chip microcomputer governor circuit, circuit for controlling motor, and described circuit for controlling motor is made up of head-shaking motor control circuit and control of Fan Motor circuit; Described acoustical-electrical transducer 11 converts discrete sound signal to discrete individual pulse, input single-chip microcomputer governor circuit, send different control signals according to the pulse number in the unit time after single-chip microcomputer governor circuit received pulse, output to head-shaking motor control circuit or control of Fan Motor circuit respectively.Be provided with timer sum counter in described single-chip microcomputer governor circuit, all have 2 ~ 3 counters in the chip of wherein each single-chip microcomputer, able to programme being used for adds up pulse number.The described unit time is in 2s.
During use, the number of times that people in unit time 2s claps one's hands is changed into discrete individual pulse by acoustical-electrical transducer 11: when the pulse number in the unit time is 1, the control signal sent is outputted to control of Fan Motor circuit by single-chip microcomputer governor circuit, controls unlatching or the closedown of fan; When pulse number in unit time is 2, the control signal sent is outputted to control of Fan Motor circuit by single-chip microcomputer governor circuit, and the speed controlling fan circulates by the mode of low speed → middling speed → at a high speed → low speed; Whether, when the pulse number in the unit time is 3, the control signal sent is outputted to head-shaking motor control circuit by single-chip microcomputer governor circuit, control fan and shake the head.
Described support 2 is provided with and shakes fast control knob 21, and it is connected with head-shaking motor control circuit, controls the speed of shaking the head of fan.
First plugged in by socket during work, be in holding state, controlling method is as follows more specifically:
(1) clap one's hands in the unit time (): start or stop
When clapping one's hands (1 pulse), if electric fan stopped in advance before this, then initialization, electric fan starts, and rotates with geared-down speed, shakes the head with the speed loop of shaking the head pre-set; If electric fan rotated in advance before this, when clapping one's hands (1 pulse), single-chip microcomputer governor circuit output motor stall signal, then stopping fan rotation and shaking the head.
If when being in holding state, do not clap one's hands in the unit time or clap one's hands more than 2 times (namely do not receive pulse or receive more than 2 or 2 pulses), fan is still in holding state.
(2) to clap one's hands continuously in the unit time two sound (whip): after startup, regulate and control wind speed
After startup, clap one's hands two sound time (2 pulses), electric fan accelerates one grade, enters mid ranger; To clap one's hands again two sound; Accelerate one grade again, enter top gear; Clap one's hands two sound (2 pulses), electric fan wind speed then gets back to again initial low grade again.Namely the mode iterative cycles pressing low speed → middling speed → at a high speed → low speed controls fan wind speed.
(3) to clap one's hands continuously in the unit time three sound (whip): control after starting to shake the head
After startup, clap one's hands three sound time (3 pulses), control the head-shaking device of electric fan, allow it rest on to clap one's hands moment position, no longer continue to shake the head; Continuous shooting three sound (3 pulses) again, electric fan starts again circulation and shakes the head; Continuous shooting three sound again; Rocking device for electric fan suspends again somewhere.
When clapping one's hands more than three sound in the unit time, electric fan attonity performs.
(4) electric fan support 2 arranges one and shakes fast control knob 21, and point low speed and middling speed two grades, can pre-set required speed of shaking the head before use.
Described single-chip microcomputer governor circuit is made up of singlechip chip and peripheral circuit.When writing primary control program, for often kind of working state, a state variable is set respectively, is used for recording current place state: represent with sate1 the state of starting or stoping, can value 0 or 1, represent respectively and stop or starting state; State2 represents speed governing state, can value 1,2,3, represents low speed, middling speed and fast state respectively; State3 represents the state of shaking the head, can value 0 and 1, represents that time-out is shaken the head and shake the head state respectively.Electric fan often enters a new state, and just correspondence revises the value of state1, state2, state3 automatically, and to ensure the accuracy of next control procedure, specific procedure control procedure is as shown in Fig. 3 ~ 4.
Described head-shaking motor control circuit is direct current motor drive circuit, and control of Fan Motor circuit is AC electric machine driving circuit, comprises many grades of alignment circuits.
The utility model Intellignet simple sound control electric fan, according to the number of clapping one's hands, just can control the switch of electric fan, speed governing and shake the head, and control command simplicity of design is easy to use, easily realizes.
