ABSTRACT:
TECHNICAL FIELD
This invention relates to automatically entering elevator calls to predetermined destinations which are altered after each trip, which are displayed in a timely fashion to the bearer, and which may be altered by the bearer.
BACKGROUND ART
The automatic entry of elevator calls, remotely, from devices carried by potential passengers has recently received much attention. Such automatic call placement systems typically match the floor upon which a passenger approaches an elevator with the usual destination of said passenger when entering the elevator at said floor. In U.S. Pat. No. 5,689,094, the passenger is not informed of his destination floor until he is at the elevator, and the only way to change it, if he desires to do so, is by means of building-mounted destination entry keys. No provision is made for identifying the particular passenger to which the newly entered destination relates. In U.S. Pat. No. 4,558,298, only the last call destination entered by voice of a passenger into microphones disposed on the building can be changed by a new destination by voice, if voice prints of the two destinations match. While this solves the problem of matching the present destination to the previous destination which it is to replace. There is no provision for automatic destination entry, Japanese published application 5-278962(A) discloses portable devices, each of which are essentially a portable car operating panel with all of the same buttons and indicators that a normal car operating panel has, thereby avoiding the necessity for each passenger to reach the car operating panel. The device therein has a cancel button to allow it to cancel a car call that it has just made. However, this does not result in changing predetermined destinations for automatic call placement. In Canadian patent publication 2,238,210, a call entered into a portable device can be changed only before it is interrogated by the building, and not after the call has been registered. In commonly owned U.S. patent application Ser. No. 09/111,077, filed Jul. 7, 1998, now U.S. Pat. No. 5,952,626 a portable, remote call entering device transmits its identification number with every call request and with every call cancellation request; however, this does not provide for altering the automatic destination floor nor informing the passenger thereof.
DISCLOSURE OF INVENTION
Objects of the invention include provision of automatic shifting from one automatic destination for a passenger, to another automatic destination for the passenger, as the passenger makes successive trips; informing the passenger of the destination that will be automatically entered; allowing the passenger to designate the destination in an overriding fashion; and controlling automatic destinations either in a centralized fashion, or in a distributed fashion.
According to the present invention, communication between a first transponder and a card borne by each passenger will cause the card to display the current next destination that will automatically be registered for the passenger bearing the card, unless said destination is designated as “unfixed”, in which case a new next destination will be determined from the passenger's destination record and the floor of the beacon; communication between the card and a second transponder will cause a hall call to be entered for the passenger. Destinations entered by the passenger are designated as “fixed”, and destinations are designated as “unfixed” after they have been used to enter a car call for the passenger. The determination of destinations and designating them as “fixed” or “unfixed” may either be done centrally by signal processing means in the building, or may be done in a distributed fashion by signal processing means contained within each card carried by the passengers, or part centrally and part distributed.
Other objects, features and advantages of the present invention will become more apparent in the light of the following detailed description of exemplary embodiments thereof, as illustrated in the accompanying drawing.
