Pulse-supervised multi-vehicle transportation system

Abstract

Abstract AN IMPROVED MULTI-CAR ELEVATOR SUPERVISORY SYSTEM WHEREIN MOVEMENT OF THE CARS IS CONTROLLED BY PULSE DRIVE LOGIC CIRCUITS. IN ADDITION TO THE PREDETERMINED NUMBER OF CAR AND FIRST DIRECTION CORRIDOR CALLS ALLOCATED TO CARS TRAVELING IN THE FIRST DIRECTION TO SERVE FIRST DIRECTION CALLS, A PREDETERMINED NUMBER OF FIRST DIRECTION CORRIDOR CALLS ARE ALLOCATED TO CARS WHILE TRAVELING IN THE SECOND DIRECTION ON ASSIGNMENT TO SERVE FIRST DIRECTION CALLS. EXESS CORRIDOR CALLS NOT ALLOCATED TO CARS SERVING IN THE DIRECTION OF THE CALLS OR TRAVELING IN THE OPPOSITE DIRECTION TO SERVE IN THE DIRECTION OF TEH CALLS CREATE A DEMAND FOR AN EXTRA CR. CARS TRAVELING IN TEH SECOND DIRECTION TO SERVE FIRST DIRECTION CORRIDOR CALLS ARE NOT ASSIGNED TO ANY SPECIFIC FIRST DIRECTION CORRIDOR CALL. THEY ALL TRAVEL FOR THE FARTHEST FIRST DIRECTION DEMAND UNTIL ONE CAR HAS PASSED ALL THE FIRST DIRECTION DEMANDS EXCEPT THE FARTHEST ONE AT WHICH TIME IS COMMITTED TO THE FARTHEST DEMAND WHILE THE OTHER CARS ARE PERMITTED TO SEE THE NEXT FARTHEST DEMAND. IF THE DISTANCE BETWEEN CORRIDOR CALLS IS EXCESSIVE, A DEMAND FOR AN EXTRA CAR IS CREATED EVEN THOUGH LESS THAN THE PREDETERMINED NUMBER OF CALLS HAVE BEEN ALLOCATED TO THE ASSIGNED CARS. CORRIDOR CALLS REGISTERED FOR MORE THAN A PREDETERMINED TIME ARE GIVEN PREFERRED TREATMENT. SINCE CARS ON ASSIGNMENT TO SERVE PREFERRED CALLS BYPASS NONPREFFERED CALLS, THE SYSTEM CONSIDERS THESE CARS TO BE APPROACHING THE PREFERRED CALLS REGARDLESS OF THEIR ACTUAL POSITION SO THAT THE NORMAL CALL ALLOCATING CIRCUITS MAY BE UTILIZED TO ALLOCATE THE BYPASSED CALLS TO OTHER CARS. WHEN NO CAR IS LOCATED AT THE LOWER TERMINAL FLOOR AN ARTIFICIAL DEMAND FOR A CAR TO BE SENT TO THE LOWER TERMINAL IS CREATED UNLESS A CAR IS APPROACHING THE MAIN FLOR WITH LESS THAN A PREDETERMINED NUMBER OF CALLS ALLOCATED TO IT. IN THE ABSENCE OF SUCH A CAR, A CAR IS ASSIGNED TO SERVE THE ARITFICIAL DEMAND AT THE LOWER TERMINAL, HOWEVER, IT WILL REVERSE AND SERVE THE LOWEST ACTUAL UP CORRIDOR CALL BETWEEN IT AND THE LOWER TERMINAL FLOOR SHOULD A CALL BE REGISTERED. A DOWN TRAVELING CAR WILL BYPASS ALL REMIAINING DOWN CORRIDOR CALLS AFTER MAKING A PREDETERMINED NUMBER OF STOPS WITH PASSENGERS ON BOARD. SUCH A CAR WILL NOT BE CONSIDERED IN THE ALLOCATION OF CALLS TO CARS SERVING DOWN CORRIDOR CALLS.
