摘要： An elevator system having a plurality of elevator cars and supervisory control for directing their movement in a building to efficiently serve the floors therein. The supervisory control divides the work load uniformly among the elevator cars by periodically assigning, clearing and reassigning service directions from the floors to the cars according to a predetermined strategy. The predetermined strategy accords special treatment for assigning the service directions from floors at which each car will stop and depart in a predetermined direction due to register car calls. The strategy includes special limitations on such car call related assignments to improve elevator service, with one embodiment limiting such car call related assignments to a predetermined number N, which are the N closest car calls ahead of the car. Another embodiment provides a dynamic limitation on car call related assignments by counting the stops due to car calls and previously committed hall calls ahead of each car, and making a car call related assignment only when it is within a predetermined number of stops ahead of the car.

摘要： An elevator system including apparatus for detecting mechanical damage to the elevator system, such as might be caused by an earthquake. A cable strung in the hoistway is reeved about a plurality of sheaves carried by the counterweight. Normal operation of the counterweight maintains a predetermined tension in the cable, which predetermined tension is used to maintain a switch in a first condition. Abnormal movement of the counterweight outside of its vertical travel path changes the tension in the cable and operates the switch to a second condition which modifies the operation of the elevator system.

摘要： An elevator system for a building having a plurality of floors, including supervisory system control for controlling a plurality of elevator cars to answer calls for elevator service from the plurality of floors. The system control assigns unassigned service directions from the plurality of floors to each of the elevator cars, until meeting a predetermined dynamic limiting average. The assignments are made to one car at a time, proceeding to the next when a predetermined limiting average is met. The order in which the cars are selected for assignment is a dynamic order, responsive to the relative work loads of the cars. The assignments are made to each car, starting in a predetermined direction from each car's position, and are terminated a predetermined travel distance from the car, if not terminated sooner due to a limiting dynamic average. A predetermined minimum limiting dynamic average may be set, to control the rate at which idle cars become busy cars when traffic increases.
