Referring to fig. 1 to 7, the working principle of the intelligent toilet seat turning cover plate circuit of the present embodiment is as follows:
When the seat cover needs to be turned over by the intelligent closestool, a main control chip U1 of the main control circuit sends out a PWM pulse control signal, the PWM pulse control signal is output to the ring turning and cover turning motor driving circuit through the signal gating circuit, the corresponding full bridge circuit is enabled to operate, the direct current brushless motor gear box is driven to rotate positively, and the seat cover plate is correspondingly turned over upwards. In the process that the seat cover plate rises, the seat cover plate angle can increase gradually, and the potentiometer value can constantly increase on the motor this moment, and main control chip U1 constantly monitors the angle change condition of seat cover plate through the ADC sampling to constantly adjust PWM pulse width duty ratio value, thereby adjustment motor output torque makes the seat cover plate can rise with the uniform velocity.
When the seat cover plate rises to the end point, the main control chip U1 can reach the maximum value through the ADC value of the potentiometer on the motor, so that the cover plate can be known to be in place, the PWM pulse signal is stopped, the motor gear box is powered off, and the seat cover plate stops moving.
When the intelligent closestool closes the seat cover plate, the main control chip U1 sends out a reverse PWM pulse control signal, and the reverse PWM pulse control signal is output to the ring-turning flip motor driving circuit through the signal gating circuit U2, so that the corresponding full bridge circuit operates to drive the direct current brushless motor gear box to reverse, and the seat cover plate correspondingly turns downwards. In the downward overturning process, the angle of the seat cover plate can be gradually reduced, the potentiometer value on the motor can be continuously reduced at the moment, the main control chip U1 continuously monitors the angle change condition of the seat cover plate through ADC sampling, and the duty ratio value of the reverse PWM pulse width is continuously adjusted, so that the output torque of the motor is adjusted, the uniform speed of the seat cover plate is reduced, and the slow reduction effect is achieved. When the seat cover plate falls to the initial position, the main control chip U1 reaches the minimum value through the potentiometer ADC value on the motor, so that the cover plate is known to be in place, the PWM pulse signal is stopped, the motor gear box is powered off, and the cover plate stops moving.
When the intelligent closestool is in an idle state or a power-saving state for a long time, the main control chip U1 can enable the motor driver M1 to enter a low power consumption mode by controlling the nsleep interface of the motor driver U3, so that the energy-saving purpose is achieved. The intelligent closestool turns over circle and turns over apron circuit of this embodiment still adopts the current control circuit to be used for the protection of system when overcurrent, appears stifled commentaries on classics, artificial interference or other abnormal conditions in the twinkling of an eye in the motor gear case, and it detects motor operating current through an external current sampling resistance, when detecting the electric current and being greater than reference current, closes full-bridge pipe MOSFET.
The current-limiting protection formula is as follows:
Wherein Vref is a reference voltage, generally 3.3V, when the temperature of the motor driver M1 is too high and reaches 160 ℃, Rsense is a sampling resistor, which must be less than 1 Ω, and the motor driver M1 turns off the full-bridge MOSFET.
Therefore the utility model discloses the circuit adopts the combination of low-power chip, and system reliability is high, and circuit structure is succinct, and standby power is low, and it is big to cause power when avoiding adopting discrete component simultaneously, and volume space is big, has multiple protect function simultaneously.
