Abstract
PURPOSE: To improve the maintenance property and the accuracy of detection of position, by using a pulse counter.
CONSTITUTION: A perforated tape 13 is provided in an elevator duct in the moving direction of a gondola 8 and a proximity switch 15 is attached to the donlola so that a pulse generator is formed. The pulse generator is connected to a microcomputer 20 through a buffer register 17, an updown counter 18 and input/output regiters 19a, 19c. When a perforated hole 14 is detected by the proximity switch 15, a pulse is generated. The pulse is added to the content of the updown counter 18 when the gondola is moving up. The pulse is stored into an input/output register 19b when the gondola is moving down. A central processing unit 23 compares data in a read-only memory 21 with the number of pulses stored in the register 19 and corresponding to the position of the gondola to apply a deceleration instructing signal 27 to a driving unit when the gondola can be decelerated and stopped. Therefore, the number of mechanical contacts for switching is greatly reduced and the accuracy of detection of the position depends on the spacing between the perforated holes 14.
