Problems solved by technology

[0002] At present, when the door opener is closing the door, due to the superposition of the speed of the door and the speed of the wind, the door will generate a large impact force. The resistance of the machine room alone is not reliable for wind protection. The door is easily out of control due to the impact of the wind, resulting in Accident

Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] Such as figure 1 Shown is the hardware structure diagram of the present invention, when a person enters the sensing area of ​​the sensor and moves, the sensor will process the signal received by the interface circuit and then send it to the MCU, and the MCU will issue a door opening command signal, and the analog door will be simulated through A / D conversion. The signal is transmitted to the motor control chip, and the motor control chip outputs the corresponding PWM waveform after receiving the signal and drives the motor to run after passing through the drive circuit to open the door.

[0028] The motor speed measuring chip (MC33035) converts the detected frequency into a corresponding level signal, and then converts it into a digital signal through D / A conversion and feeds it back to the MCU. To control the motor for precise speed r...

Abstract

The invention relates to a closed-loop automatic control device and a method of a door opener. An output end of a MCU control chip is connected with an input end of a motor control chip through an A / D conversion chip; an input end of a driving circuit is connected with an output end of the motor control chip; an output end of the driving circuit is connected with an input end of a motor; one end of a motor speed measuring chip is connected with a motor, and the other end is connected to an input end of the MCU control chip through the A / D conversion chip; one end of a current sampling chip is connected with the driving circuit, and the other end is connected to the input end of the MCU control chip through the A / D conversion chip; and the MCU control chip is connected with a sensor through an interface circuit. A method of combining a closed-loop feedback principle with a PWM pulse width modulation signal is used for enabling a door to be decelerated under the wind impact so as to generate excellent wind resistance.

Description

technical field [0001] The invention relates to the field of door openers, in particular to a closed-loop automatic control device and method for door openers. Background technique [0002] At present, when the door opener is closing the door, due to the superposition of the speed of the door and the speed of the wind, the door will generate a large impact force. The resistance of the machine room alone is not reliable for wind protection. The door is easily out of control due to the impact of the wind, resulting in Accident. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a method of combining the closed-loop feedback principle with the PWM pulse width modulation signal, so that the door can be decelerated under the impact of wind to produce good wind resistance. [0004] The technical scheme that the present invention adopts for realizing the above object is: [0005] A closed-loop automatic control device ...
