Abstract

1281970 Lift control systems WESTING- HOUSE ELECTRIC CORP 28 Oct 1970 [18 Nov 1969] 51137/70 Heading B8L In a multicar lift control system in which the flows are divided into zones and individual cars are assigned to zones when calls are registered therein (i.e. one car is assigned to deal with all calls registered in a given zone at any one time) additional assigning means are provided which send an additional available car to a zone already provided for after all the zones having calls have been provided for. The normal system for assigning available cars to zones having calls is as described in Specification 949,761. However, in that system only one car would be assigned to deal with several calls if they are all in the same zone, even though another car is available. With the addition of the present system, relay circuits, controlled by the output of a resistor bridge network whose arms represent registered calls and assigned cars respectively, assign a car which remains available at the end of the normal process to answer a call not yet dealt with by its normally assigned car. Fig. 2 illustrates an example in which a down call on floor 6 is assigned to car B already in its zone, down calls on floors 4 and 5 are both assigned by the normal process to car C, leaving car A available. The present system assigns A to answer call 5, leaving car C to answer call 4 only. The complete system is described only in conjunction with Specification 949,761.
