1. a retractable door automatic correction method comprises the following steps:

  • Step 1 is used the retractable door automatic deviation rectifying device, and microprocessor receives the switch gate order;

    The architectural feature of described retractable door automatic deviation rectifying device is;

    comprise push-button unit, remote control unit, the charactron display unit, alarm relay, motor relay and microprocessor, described microprocessor by data wire or control line respectively with described push-button unit, remote control unit, the charactron display unit, alarm relay, motor relay links to each other, described motor relay adopts bi-motor synchronous working mode, the power subsystem power supply, one group of pre-buried on door running body track equally spaced magnetic navigation identifies, 4 magnetic induction sensors are installed for the detection to the magnetic navigation sign on the trackless door, these 4 sensor straight lines arrange and perpendicular to traffic direction, 2 wherein are used for navigation, and 2 of the outside are used for correction;

    Comprise the navigation detecting unit, described navigation detecting unit is made of a plurality of sensors and magnetic navigation sign, and described microprocessor is proofreaied and correct by magnetic navigation information and magnetic navigation sign that described sensor detects, makes a running body on correct track;

    Comprise soft starting circuit, described soft starting circuit control motor relay and alarm relay, described microprocessor is realized the soft start of motor by soft starting circuit;

    Comprise the infrared anti-collision detecting unit, described infrared anti-collision detecting unit links to each other with described microprocessor, realizes intelligent distinguishing infrared anti-collision function;

    Comprise spacing detecting unit, described microprocessor realizes the door control of body position and cutting out of power supply by spacing detecting unit;

    Step 2, the motion of bi-motor synchronous operation driving gate body, the signal of device and real time detecting sensor, does judging have navigation signal in blanking time? if then execution in step four;

    If nothing judges then whether the reverse direction operation number of times equals setting value, is not equal to setting value and namely carries out next step, and equaling setting value is that bi-motor stops;

    Step 3, bi-motor turns round in the other direction, does judging again have navigation signal in blanking time? if have, then the reverse direction operation number of times adds 1, skips to step 2, the operation of bi-motor positive direction;

    If nothing, then bi-motor stops;

    Has step 4 judged whether deviation correcting signal? if have, the motor intermittent operation of the direction of then rectifying a deviation, and another motor moves always, utilizes the deflection of the asynchronous operation generation of bi-motor, and a body is got back on the correct running orbit gradually;

    If nothing is then carried out next step;

    Step 5, device control bi-motor returns to the synchronous operation state;

    Step 6 has judged whether to stop limit signal, if having, then bi-motor stops;

    If nothing then continues to have judged whether to cease and desist order, ceasing and desisting order is that bi-motor stops, and namely skips to step 2 without ceasing and desisting order, the operation of bi-motor positive direction.
