Abstract
Abstract Procedure for selecting an elevator in a group consisting of elevators (2-7) serving the floors (K1-K18) of a building (1), each floor being provided with call input devices (11-14) for the input of calls, said elevator group having a group control unit (21,22) controlling the group and provided with at least one computer. On the basis of the call sent by a call input device, the group control unit finds out which call input device has been used for issuing the call and selects one of the elevators (2-7) serving the floor in question on the basis of the passengers' positions on the landing as determined from the information thus obtained. <IMAGE>

112 words
Procedure for selecting an elevator in a group consisting of elevators (2-7) serving the floors (K1-K18) of a building (1), each floor being provided with call input devices (11-14) for the input of calls, said elevator group having a group control unit (21,22) controlling the group and provided with at least one computer, characterized in that the group control unit, based on the call sent by a call input device, finds out which call input device has been used for issuing the call and selects one of the elevators (2-7) serving the floor in question on the basis of the passengers' positions on the landing as determined from the information thus obtained.
Claim 2
Dependent Claim
56 words
Procedure according to claim 1, characterized in that the group control system determines the distance of the passengers on each floor from the doors (2'-7') of different elevators of the group on the floor in question, and that said distance is the basis for the selection of the elevator to be sent to serve the call.
Claim 3
Dependent Claim
64 words
Procedure according to claim 1 or 2, whereby the control system first performs a normal optimiztion to select the elevators to which the call could be allocated, characterized in that, after the normal optimization, an additional optimization is performed to choose from the elevators selected by the normal optimization the one which is to serve the call on the basis of said distance data.
Claim 4
Dependent Claim
44 words
Procedure according to any one of the preceding claims, characterized in that, to allow additional optimization, the elevators among which the one to be selected in the first place to serve a call are defined for each call input device in the elevator lobby.
Claim 5
Dependent Claim
38 words
Procedure according to any one of the preceding claims, characterized in that the elevator is selected among those located on the same side of the elevator lobby as the call input device through which the call was issued.
Claim 6
Dependent Claim
26 words
Procedure according to any one of the preceding claims, characterized in that the additional optimization is performed on the basis of the oldest call in force.
Claim 7
Dependent Claim
54 words
Procedure according to claim 1, characterized in that it is also possible to select an elevator located farther away from the call input device through which the call was issued, in which case the door-open time for the elevator is temporarily prolonged and the advance signalling indicating its arrival is given earlier than normal.
Claim 8
Dependent Claim
40 words
Procedure according to any one of the preceding claims, characterized in that, to guide the passengers, the signal light indicating the registration of a call is lit only for the call input device through which a call was issued first.
Claim 9
Dependent Claim
55 words
Procedure according to any one of the preceding claims, characterized in that, to guide the passengers in a situation where calls are issued via several call input devices in the lobby, the signal light indicating the registration of a call is lit only for those call input devices through which a call has been issued.
