Automatic door is how to do when someone came to the door?
Mainly by the door above the sensor, the sensor is generally two, a far-infrared, a microwave, far infrared light affected by the relatively large, so not stable, microwave self-induction moving objects can not Induction of prohibited objects, that is, if you stand in the middle of the door does not move, the door will automatically shut up to hold you, then the best way is to install the microwave sensor and then in the middle of the door to install a set of infrared on the radio Closing the door. Microwave sensors are currently more popular, and far out of the basic infrared has been eliminated.
Induction automatic doors a lot of types, is only a common translation of automatic doors as an example to introduce its basic working principle:
?(1) the main controller: it is the command center of the automatic door, through the internal command program with large-scale integrated block, issued a corresponding instruction, command motor or electric lock sys
tem work, and people through the main controller to adjust the door open Speed, opening amplitude and other parameters;
?(2) sensor detectors: responsible for the collection of external signal devices, such as people's eyes, when a moving object into its scope of work, it can give the main controller a pulse signal;
?(3) power motor: its task is to open the door and the door to provide the main force to control the door of the acceleration and deceleration operation;
?(4) door spreader wheel system: for hanging activities of the door, while driving under the power to drive the door run;
?(5) door travel track: the constraints of the door of the spreader wheel system to make it in a specific direction;
?(6) timing belt: for the transmission of motor power generated by traction door spreader wheel system;
?(7) the lower guide system: This is the lower part of the door guide and positioning device to prevent the door when running before and after the door swing;
??Note: the door to complete a switch of the workflow: the sensor detects someone to enter ----- pulse signal will be passed to the main controller --- the main controller to determine the motor after the judge - the motor will run after the power Pass to the timing belt - the timing belt will pass the power to the spreader system to open the door - the door is opened by the controller to make a judgment --- to close the door to inform the motor to do reverse movement, close the door.
