Problems solved by technology

[0004] The problem with solutions according to the current state of the art using conventional control and zoning for controlling the elevators in an elevator bank is that, under small traffic conditions, when optimization is applied exclusively to capacity or travel time Crowding occurs in the elevator lobby when
In order to provide space for passengers in the elevator lobby, it is necessary to build a larger elevator lobby, which in turn will be too expensive in large buildings
[0005] Another source of problems is the fact that when using conventional controls in elevator group control, empty elevators often pass floors where passengers are waiting for elevators, which can be annoying for waiting passengers

Embodiment Construction

[0025] figure 1 The diagram in , visualizes the method of the invention in which the call entry to the elevators in the elevator bank is implemented using the destination floor call entry and, depending on the traffic intensity and type, using multi-objective optimization or dynamic partitioning as the control method, To optimize the traffic volume in the elevator group. The elevator group is controlled by a computer configured for this purpose.

[0026] The information used by the group control system of the elevator group is obtained from traffic forecasts regarding the current traffic type and intensity. In the forecast statistics, information is gathered, for example, from car load measuring devices and / or light units and / or destination floor call buttons, which can obviously be used in conjunction with destination control. Information representing the time of arrival of the transport and the floors on which passengers arrive and depart is preferably obtained from the de...

Abstract

The invention concerns a method for controlling the elevators in an elevator group when destination floor call input is used and the traffic within the elevator group is to be optimized. According to the inventive concept of the method, based on traffic intensity, a cost function is optimized by changing the number of cost criteria from one to several and back and weighting the criteria in different ways in the aforesaid cost function.

Description

technical field [0001] The invention relates to a method as defined in the preamble of claim 1 for controlling elevators in an elevator group. The present invention relates to an elevator group control method using destination floor call input. Background technique [0002] The prior art is described in EP patent specification 356731 (B66B 1 / 20), which discloses an elevator group control system using immediate assignment of destination calls, wherein, immediately after an incoming call, only the incoming floor for the new call and the destination floor to calculate the running cost corresponding to the passenger waiting time. Afterwards, these costs are compared, whereby the call is assigned to the elevator with the least operating costs. [0003] The prior art is also described in FI application document 972937 (B66B 1 / 20), which discloses such an elevator group control system, wherein the optimization is based on the traffic situation, ie the current dominant type and tr...
