The output of detector or sensor is delivered to respectively through central processing system and is just being reversed control circuit sum digit analogy change-over circuit.The anaiog signal of numerical digit analogy change-over circuit output send comparison circuit with the input voltage of motor again through the amplification of amplifying circuit, the output of comparison circuit triggers through the signal that phase-control circuit produces again and send motor drive circuit after just reversing control circuit, and the input voltage of motor send central processing system with the motor rotary speed signal simultaneously behind the counting shaping circuit.Central processing system also is connected with memory circuit with external control circuit respectively, the external control circuit external connection keyboard.
Central processing system can receive and handle the status signal that is transmitted by detector, sends two groups of signals again, divides supplementary biography to just reversing control circuit and numerical digit analogy change-over circuit, and it also receives and handle the tach signal that is transmitted by motor.This system can connect a memory circuit and an external control circuit in addition again, can control the rotating speed of motor really.
Just reversing control circuit and receiving the signal that is transmitted by central processing system and phase-control circuit respectively, controllable motor is just being changeed or is being reversed and triggering simultaneously motor drive circuit.
But motor drive circuit starter and control motor rotary speed, though the automatic door closure or openness, and the signal of revolution state reaches comparison circuit and counting shaping circuit respectively.
Numerical digit analogy change-over circuit will convert anaiog signal to by the signal that central processing system transmits, and reach amplifying circuit.
Amplifying circuit with anaiog signal with transmit magnitude of voltage relatively by motor, if difference is then notified phase-control circuit to impel just to reverse control circuit and is made motor subtract (increasing) speed.
Phase-control circuit can produce a signal triggering and just reverse control circuit.
The counting shaping circuit calculates the rotation number of turns of motor and converts signal to and is transmitted back to central processing system again and handles it.
Memory circuit can be remembered all devices during automatic doors, empirical values such as suitable folding speed of proofreading and correct with artificial adjustment and door-plate position, and link to each other with central processing system, provide all memory documents to use to central processing system.
External control circuit can external operation keyboard etc., required data (for example speed of switch door, position, holdup time etc.) input memory circuit memory when utilizing keyboard that automatic door is moved.
Utilize the organic assembling of foregoing circuit, the control motor speed varying only starts once it in action each time.
In the recall info of memory circuit, can be provided with when making the continuous several times of automatic door can't be fully closed, just stop motor running automatically, switch to be restarted can recover all functions.
Compare with existing device for controlling automatic door, the present invention can make the action of automatic door reach smooth and easy unlatching and closed purpose, and both power savings reduce its fault rate again; Installation is easy with adjustment in addition, and prolongs motor life.
One group of signal that the present invention is sent by central processing system is after converting anaiog signal to, operational voltage value at comparison circuit and motor is made comparisons, the phase-control circuit of comparative result can being transmitted scriptures is used the control motor speed varying again, and another group signal of motor is through the counting shaping circuit, can again the revolution number of turns be informed central processing system, whether the position of its decidable automatic door is conformed to at that time translational speed, can not order about motor speed varying again if do not conform to, and when guaranteeing automatic door and a certain position with a certain speed motion, no matter make this automatic door when closure or openness, only must make motor mode execution to slow down gradually after startup, do not influence motor life and expend power supply because of repeatedly starting.In addition, can an external control circuit, make the installer of automatic door can directly adjust opening and closing amplitude, speed and the dead time of automatic door in the mode of line traffic control, needn't be time-consuming, the effort climbing adjusts to the door top, installer needn't can be installed for specialty or experienced person.
