Definitions

  • the invention relates in general to elevator systems, and more specifically to elevator systems in which a plurality of elevator cars are controlled by a central dispatching control apparatus.
  • the highest down call registered receives special priority, and when a car is assigned to answer the highest down call registered its assignment will be changed if, while on its way to answer this call, a second and still higher down call is registered.
  • the first call now unassigned, will be assigned to another available car, or the next car that becomes available, i.e., one not currently busy serving a call for elevator service.
  • This arrangement often results in two cars traveling substantially the full length of the building, as the first car may have been the closest available car to the first highest down call registered, but it may not be the closest car to the subsequently registered highest down call.
  • An available car near the second call will not be assigned to the second call, as the first call will automatically be assigned to the subsequently registered highest down call.
  • the second car may be assigned to the first call.
  • the present invention is a new and improved elevator system, and method of dispatching cars in an elevator system, to serve calls for service therein.
  • a programmable digital computer system processor is used, with sequential processing of data, and sequential generation of command and status signals.
  • the floor calls are placed in a call table, with new floor calls being allocated to the closest suitably conditioned elevator car which is already busy serving calls for elevator service, and if the call cannot be so allocated, a demand signal is generated relative to the call.
  • the closest non-busy or available car is assigned specifically to a demand call.
  • the floor calls are marked in the call table when they are allocated to a car, or processed by assigning'a car to them, and they are also marked as to whether a demand signal was created for them.
  • the whole call table is processed at rapid intervals, which includes calls previously processed.
  • the invention distinguishes between the two categories of processed calls, providing a different strategy for calls which were originally processed by allocation to a running call and those originally processed by assigning a non-busy or available car to the call.
  • the call is marked as an assigned-demand call in the call table.
  • the strategy is to confirm that a car has been given the assignment of stopping at the floor of this call, and if this is verified, the processing of this call is complete, and the assignment is not changed. If a car is not found with this assignment, the assigned status of the call is deleted and the call reprocessed by either allocating the call to the closest suitably conditioned busy or running car, or by creating a demand signal for it and assigning the closest available car to the demand call.
  • the call is in the category of having been allocated to a car, it is marked assigned but not as a demand call. Upon reprocessing this category of call, the assigned status is always deleted and the call reprocessed by allocating the call to the closest suitably conditioned car, or by creating a demand signal relative to the call and assigning the closest available non-busy car.
  • the invention follows an initialization procedure which is normally only used upon start-up of the system, which procedure clears the call table and car assignment tables. If there would happen to be a lost call for elevator service, it would then appear as a new call in the system and be processed in the same manner as a new call.
  • the invention retains the priority of the highest down call, and does so with a different strategy which prevents two cars from effectively changing places in the building, and thus it eliminates needless travel and shortens waiting time.
  • a down call which is the highest down call and it cannot be allocated to a busy car
  • a demand signal is created which results in the closest available non-busy car being assigned to the call. If a higher down call is registered while the first car is on its way to its previously highest
