Destination entry system with delayed elevator car assignment

摘要

An elevator system utilizes a destination entry control technique and delays indicating which car is assigned to a request to allow an individual to arrive near an elevator lobby. An elevator group assignment is made responsive to a destination request. An indication regarding the group assignment is provided to a passenger within a first time from the receipt of the request. A second indication regarding a car assigned to carry that passenger to the desired destination is provided at a second, later time from the request. Separating out the group assignment indication and the car assignment indication is accomplished in one example by providing separate interfaces at different locations within a building, for example. A disclosed example includes making the group assignment and car assignments at separate times corresponding to a difference in time between receipt of the initial request and the passenger's expected or actual arrival in the vicinity of the assigned elevator group.
