Abstract: A zoned elevator control system for a group of cars in which the cars are distributed on a predetermined apportioned basis into various zones of the building for assignment thereto, whereupon in the absence of calls each car is brought to a stop at a landing in a zone to which it is assigned. Thereafter in a zone to which a car is assigned the response to the first landing call is limited to a car assigned to that zone. A landing call in a zone to which no car is assigned starts a car assigned in the nearest lower zone. The level of traffic in each zone is measured individually and is a function of the number of landing calls in registration in the respective zone. An average of a number of landing calls in all zones is derived and a comparison is made between the number of landing calls in each individual zone and the average number of landings calls. Whenever the number in any zone exceeds the average by a predetermined amount it signifies that the zone is a heavy traffic zone. As a result the limitation on the response to landing calls to a car assigned to that zone is removed. This enables a car in the nearest lower zone to respond to landing calls in the heavy traffic zone notwithstanding another car is assigned to that zone. In addition while the heavy traffic demand continues any car in a zone which is in excess of the apportioned number of cars for that zone and therefore is not assigned to that zone is caused to travel toward the heavy traffic zone. All cars entering the heavy traffic zone while the heavy traffic demand continues are assigned to that zone and are thereby prevented from traveling to an unoccupied zone as they otherwise would.

Abstract: Improved solid state control systems for elevators in which the solid state components are mounted on printed circuit boards, the conductor paths of which interconnect the components of each individual board and connect them to circuit terminals which enable the connections of various components on different boards to each other. A first plurality of printed circuit boards whose components are properly interconnected provides basic control circuitry for one elevator car operating in a single car system. When appropriately connected to the control equipment associated with its car so as to receive control signals therefrom this circuitry operates in response to such signals in a predetermined manner to control its car according to a particular mode of operation. Included among the conductor paths on the circuit boards of this first plurality and connected between circuit terminals and solid state components thereof are a number of paths which are unnecessary to the operation of the basic control circuitry. These enable the connection of auxiliary equipment to the basic control circuitry which causes that circuitry to operate differently in response to the control signals it receives from the associated control equipment even though the interconnections between the components of the basic control circuitry and the connection between it and the associated control equipment remain unaltered. The printed circuit boards employed in supervisory control systems for groups of elevator cars possess a similar such universal character.
