Abstract:
A method for controlling opening/closing of a door in an automatic door system comprises the steps of causing the door to conduct opening operation to its opening-stop limit by an initial opening signal transmitted after the power supply is put to work and the arrival of the door at its closing-stop point is confirmed, and measuring the opening stroke at that time; causing the door to conduct closing operation to its closing-stop point when it is stopped at opening-stop point and no opening signal is inputted, and measuring the closing stroke of the door at that time; computing the difference between the measured opening and closing strokes upon stopping of the door at its closing-stop point; and outputting a signal of abnormal condition if the difference is more than a present value, or causing the door to conduct normal opening/closing operation if it is less than the preset value. Thus, the opening/closing operation of the door can be made at a high speed by a preset distance in the beginning of the whole stroke, and thereafter at a low speed.
Abstract:
In a method for controlling an automatic door system, after a power-supply switch of the system is turned on, a door of the system initially conducts its low-speed opening/closing operation when a first human-body detection signal is inputted to the system; and then, when the door travels a distance more than a predetermined minimum door stroke, the door conducts its normal-speed opening/closing operation after completion of its traveling the predetermined minimum door stroke to enable the door to conduct its normal-speed operation within a short time after the power-supply switch is turned on.

Abstract:
An apparatus for use in an automatic door system. Means are provided which compares the current position of the running door with a deceleration point to generate a low speed command upon their coincidence. A speed control responds to decelerate the door to a selected low speed. A measuring device measures a variable run-length of the door which is subject to variations in the mechanical condition of the door. In one embodiment, the device measures a low speed run-length over which the door has moved at a low speed. A comparator compares the measured low speed run-length with a preselected optimal low speed run-length to obtain error or departure from the optimal value. A correction logic produces an updated deceleration point by removing the error from the former deceleration point.
