PROCEDURE AND APPARATUS FOR TRANSMITTING THE CALL DATA OBTAINED FROM THE CALL BUTTONS TO THE CONTROL SYSTEM OF AN ELEVATOR

摘要

The call data from the call buttons (BC1, BU1, BD1, BCi, BUi, BDi) corresponding to one floor are transmitted by turns to an elevator control system input (FLOOR1, FLOORi) corresponding to the floor in question. Transistor control signals CC, CU, CD, alternate periodically to activate car call monitoring processes to detect whether any of the call buttons are depressed. IMAGE
