On the basis of technique scheme, microprocessor unit MCU reads the value of pendulum angle probe unit in real time, thereby learns the shaking table pendulum angle, changes the thrust of electro-motor through the dutycycle that changes PWM, thereby adjusts the shaking table pendulum angle to the value of setting.
The d.c. motor job description:
The thrust that the d.c. motor velocity of rotation produces more soon is just big more, and it is just big more that thrust more greatly then promotes the shaking table pendulum angle, and the thrust that the d.c. motor velocity of rotation produces more slowly is just more little, and thrust is more little, and then to promote the shaking table pendulum angle just more little.The rotating speed of the more little then d.c. motor of the dutycycle of PWM is just slow more, and the rotating speed of the bigger then d.c. motor of the dutycycle of PWM is just fast more.MCU is exactly a velocity of rotation of controlling d.c. motor through the dutycycle size of adjustment PWM, thereby the thrust size of adjustment d.c. motor makes shaking table put the angle of setting.
Workflow for example (supposes that the pendulum angle by-pass cock is at 3 grades seat):
MCU reads swing gear data, and what read is 3 grades, knows that then pendulum angle is 18 degree.At first with less duty output PWM, promptly let shaking table swing stably with less thrust, then MCU reads the value of pendulum angle probe unit; Obtain the shaking table pendulum angle, if little 18 degree then progressively strengthen the dutycycle of PWM; Promptly progressively strengthen the thrust of electro-motor; And then read the shaking table pendulum angle, and be 18 degree up to pendulum angle, MCU is with the lasting output PWM of this dutycycle then.When MCU reads the shaking table pendulum angle greater than 18 degree, then progressively reduce the dutycycle of PWM, promptly reduce the thrust of electro-motor, be 18 degree up to the shaking table pendulum angle.
Pendulum angle just strengthens the dutycycle of PWM less than the angle of setting in a word, and pendulum angle just reduces the dutycycle of PWM greater than the angle of setting, thereby realizes that pendulum angle is locked in the angle of setting.
Note: control is waved the pwm signal of angle and is controlled pin PA2 by the single-chip microcomputer embedded software, and pwm signal is sent in simulation.
Fig. 2 is the circuit specific embodiment of the pendulum angle controller of baby's electric cradle, and the circuit working process is roughly following:
External power adapter is given U1 (buck DC-DC converter) power supply, by U1 voltage transitions is become U2 (microprocessor unit MCU), the needed burning voltage of U3 (gravity sensor).
S1 gives an order by the pendulum angle by-pass cock; The shaking table pendulum angle that notice U2 need control; U2 receives after the order through the PA1 pin (CLK) of U2, the angle parameter that PA3 pin (DATA) reads U3; Send the simulation pwm signal by the PA2 pin of U2 again and control MG1 (electro-motor) swing, and by PWM1 pin (the 19th, 20 pin) send music, can customize music according to customer demand.The big I of music by volume increase, volume reduces two by-pass cockes and S2 controls.
The pendulum angle controller of baby's electric cradle of the present invention; Be provided with the gravity sensor that is used for the wobble detection angle; No matter what plane shaking table is placed on; Swing all comes detection angles with respect to gravity vertical, and accuracy of detection is very high, and concrete precision depends on the concrete gravity sensor device of employing; After setting pendulum angle; Thrust can be adjusted automatically; Promote shaking table with less thrust earlier, progressively add high thrust after the swing again up to the angle of setting, shaking table stops (for example artificially stoping the shaking table swing) or the amplitude change diminishes greatly when detecting; Then working as pendulum angle then increases thrust less than the angle of setting, when pendulum angle then reduces thrust greater than the angle of setting.
The content of not doing in this instructions to describe in detail belongs to this area professional and technical personnel's known prior art.
