Automatic induction door working principle
The automatic door sensors to detect there is someone that is coming, the pulse signal to the main controller, main control unit and determining the notification operation of the motor, motor speed monitor and control, the sensor with chip notice motor in certain time afterburner and enter slow operation. After running a certain current motor do run forward, the dynamic force is transmitted to a synchronous belt, again by the synchronous belt to transmit the power to the spreader system to open the door and window. After the door open by the controller to make a judgment as to close, notice motor reverse movement, close the door. When the induction detector to detect a man to enter, the signal is passed to the main controller, main controller to accept to information by judging immediately notify the motor to run and monitor and control motor speed, notify the motor at a certain point in time accelerated or slowed down. Motor information and some current do forward motion, the power is transmitted to the synchronous belt, synchronous belt to transmit the power to the spreader system to open the door and window leaf open again by the controller made judge whether needs to be closed, such as door needs to be closed controller then notify the motor reverse, close the door, and so on.
Also known as microwave radar, the object movement reaction, and the reaction speed is fast for walking speed normal personnel through the place, it is once in a near the door of the staff do not want to go out and motionless, the radar will no longer reaction. Automatic door closes, there may appear clip phenomenon.
Response to the presence of an object, regardless of whether the person is moving, is in the range of the sensor's scan, it will react. The reaction rate of the infrared sensor is slower than that of the microwave sensor.
Clean inside the chassis oil, dust, check the automatic induction door parts wear, check automatic door support deviation and screw tightening situation; check the belt tightness; check the controller output, opening and closing the door width, speed, braking, etc.; check voltage parameters are normal; maintenance and replacement of damaged parts; owners must pay attention to the automatic door of regular maintenance and maintenance, automatic door due to the installation quality and the use of the environment using process will inevitably problems. |
