The invention provides an intelligent garbage cover buffer control method, which comprises the following steps:
s1, when the MCU acquires a signal that the garbage cover is about to be closed, the MCU controls the motor to rotate to drive the garbage cover to rotate towards a closing direction, and after the motor runs to a preset time threshold, the motor output is closed;
and S2, outputting a PWM signal with a preset duty ratio value by the MCU to control the motor to rotate reversely so as to generate reverse resistance, wherein the reverse resistance is smaller than the gravity of the garbage cover.
And S3, when the sensor device detects that the garbage cover is closed, the MCU closes the output, and the motor stops rotating, namely the garbage cover is buffered and closed.
In specific implementation, as shown in fig. 1, the cover closing of the garbage cover can be controlled by the transmission connection of the direct current motor and the garbage cover, and when the MCU knows that the garbage cover is about to close, the MCU sends a control signal to drive the garbage cover to close. The operating principle is that the MCU controls the motor to rotate to a preset time threshold value, namely, the garbage cover is driven to rotate to a position which is a certain angle with the cover closing plane, the motor is closed at the moment, and the gravity of the garbage cover is G = mg according to a gravity formula. The MCU outputs a PWM signal with a preset duty ratio value to control the motor to rotate reversely, so that the garbage cover generates a reverse resistance Fb, and the garbage cover at the momentWeight G1= G-Fb, where G1 is greater than Fb and much less than G; then, the gravity acceleration formula is used to obtain
Under the condition that other parameters are not changed, G1 is reduced, the gravity acceleration is also reduced, namely the garbage cover is slowly lowered. And when the sensor device detects that the garbage cover is covered, the sensor device can output a signal to the MCU, and the MCU controls the motor to stop running, namely the garbage cover is closed in a buffering manner.
Preferably, before step S1, after the MCU needs to know the signal that the garbage cover will close, the cover closing operation of steps S1 to S3 can be performed, wherein the way that the MCU knows the signal that the garbage cover will close can be designed and matched according to the actually matched garbage can structure, for example, a pressure sensor is disposed on the pedal type garbage can, and when the pedal is released, the pressure sensor transmits the signal of the cover closing operation to the MCU; if the intelligent garbage can is provided with the sensing device, when the garbage can senses that garbage is put into the garbage can, the sensing device can transmit a cover closing action signal to the MCU, so that the cover closing of the garbage cover is automatically controlled; if a switch is arranged on the intelligent garbage can, a signal of the cover closing action is transmitted to the MCU through pressing or touching the switch, so that the automatic cover closing of the garbage cover is controlled; such as to design the signals required to perform the closing action, etc., in accordance with the angle or operation of other mechanical structures.
Preferably, the time threshold is set in a range of 150ms to 500ms.
Preferably, the duty ratio value is set in a range of 30% to 70%.
It should be noted that the time threshold and duty cycle value settings should be set according to the actual trash lid weight size and the overall lid angle; specifically, if the entire closing angle is 270 °, the time threshold should be set longer, and if the entire closing angle is 90 °, the time threshold should be set shorter; in addition, the time threshold value can be set to be 25-60 degrees when the garbage cover and the covering plane are in an angle, and then the motor reversing step is carried out. Namely, under the condition that the rotating speeds are consistent, the time threshold and the garbage cover covering angle can be mutually converted. The setting of the duty ratio value is associated with the generated reverse resistance, the duty ratio value is set to be higher, the reverse resistance is large, the descending of the garbage cover is slower, the duty ratio value is set to be lower, the reverse resistance is small, and the descending of the garbage cover is relatively faster. The duty ratio value needs to be set to appropriate data according to the weight size of the trash cover and the actual demand.
As a preferred scheme, when the MCU outputs a signal to control the motor to start and rotate reversely, the motor drives the garbage cover to close the garbage cover, the motor is set to operate at 25RPM under constant torque, when the preset time threshold is 200ms, the garbage cover reaches an angle of about 25-45 ° to the horizontal plane, at this time, the motor output is closed, and the MCU outputs a PWM signal with a frequency of 15.6KHZ duty ratio of 40% to drive the motor to rotate forwardly, so that the garbage cover generates reverse resistance, and because the reverse resistance is smaller than the gravity of the garbage cover, the garbage cover slowly descends under the action of gravity.
The invention also provides an intelligent garbage cover buffering device which comprises a motor in transmission connection with the garbage cover and a motor driving module electrically connected with the motor; specifically, as shown in fig. 2, J5 represents an interface of the motor, and the output current thereof can be set to 3A.
The motor driving module comprises an MCU and a motor driving chip U2 which are electrically connected; wherein MCU controls motor driver chip U2 and then driving motor to the closed direction rotation through output signal earlier and predetermines the time threshold, and the rethread exports the PWM signal that predetermines duty ratio value and drives the motor reverse rotation for rubbish lid is because the motor reverse rotation produces the reverse resistance and slowly closes in normal rotatory closure, the reverse resistance should be less than the gravity of rubbish lid.
Preferably, the I NC2 port of the MCU is connected to the first pin of the motor driving chip U2 through the resistor R10, the I NC1 port of the MCU is connected to the second pin of the motor driving chip U2 through the resistor R36, and when the MCU outputs a high level through the I NC2 and outputs a low level through the I NC1, the motor is controlled to rotate reversely; and when the MCU outputs a low level through the INC 2 and the INC 1 outputs a PWM signal with a preset duty ratio value, the motor can be controlled to rotate forwards.
Similarly, the time threshold value is set to be 150 ms-500 ms, the duty ratio value is set to be 30% -70%, and the time threshold value and the duty ratio value are set according to the actual weight size of the garbage cover and the whole covering angle.
Preferably, the motor driving module further comprises a current sampling circuit electrically connected with the motor driving chip U2, and the current sampling circuit comprises a resistor R1, a resistor R2, and a capacitor C1; the grounding end of the motor driving chip U2 is grounded through a resistor R1, and is connected with the MCU and the grounded capacitor C1 through a resistor R2. Through the arrangement of the current sampling circuit, the change condition of the output current of the motor driving module can be detected in real time, so that the safe operation of the motor is guaranteed.
Preferably, the motor driving module further comprises a power supply filter circuit electrically connected with the motor driving chip U2, and the power supply filter circuit comprises a capacitor C2 and a capacitor C3; and after the capacitor C2 and the capacitor C3 are connected in parallel, two ends of the capacitor C2 and the capacitor C3 are respectively connected to the grounding end and the power end of the motor driving chip U2, so that the filtering effect is effectively played, and the power supply of the motor driving chip U2 is facilitated.
Preferably, the two ends of the motor are also connected in parallel with a capacitor C4, so that the motor can be subjected to filtering processing during operation.
Preferably, the MCU adopts a singlechip with the model number of HC89F 541.
Preferably, the garbage can also comprises a sensor device arranged on the garbage cover and/or the garbage can, wherein the sensor device can adopt one or more of a Hall sensor, an infrared sensor and a pressure sensor, and is used for sending a signal to the MCU to remind the MCU to drive the motor to stop running when the garbage cover is closed.
For example, if a hall sensor is used as the sensor device, a magnet may be disposed on the trash cover, and a hall sensor may be disposed on the trash can, wherein the hall sensor is electrically connected to the MCU through a circuit, specifically as shown in fig. 2, and U3 is the hall sensor.
As a preferable scheme, in the operation process of the cover closing action, after the MCU has sent a signal to the motor to rotate in the reverse direction, if the sensor device has not detected that the garbage cover is closed, the output of the MCU is automatically turned off within a preset time to stop the operation of the motor. Wherein, sensor device does not detect the rubbish lid all the time and is concerned about, probably has rubbish to surpass the garbage bin top and leads to the rubbish lid to close totally, has the foreign matter to block the garbage bin and sensor device phenomenon such as unable operation, consequently, on this basis, still can set up alarm device to remind the user to look over the situation.
