Embodiment Construction

[0027] figure 1 A block diagram representing a power model of an elevator system according to the invention is shown. In this power model, the power flow in the elevator system is described by means of the elevator system parameters 2 , 3 , 4 , 13 . Power is supplied to the elevator system from a power source 27, which in this example is a network supply, but which could also be a generator, for example. Motor power supply 14 , elevator control panel 29 and lighting 30 receive power supplied to them from power supply 27 . The motor driver comprises blocks describing the power flow in the motor power supply 14 and the elevator motor 15 . The elevator car, counterweight and elevator ropes form a block 17 describing the power flow in the elevator shaft mechanism. Power flows from the elevator traction sheave 16 to the elevator shaft mechanism via the elevator ropes.

Abstract

The invention relates to an arrangement and a method for the adaptation of parameters in a transport system. The arrangement of the invention comprises a power model (1), wherein power flow in the transport system is described by means of transport system parameters (2, 3, 4, 13), which include input parameters (2, 3, 13) and status parameters (4). The arrangement also comprises the determination of at least a first (2) and a second (2) input parameter, and the power model (1) is updated on the basis of at least the first input parameter (2). At least one transport system status parameter (4) is adapted using at least the updated power model (1) and the second input parameter (3) thus determined.

Description

technical field [0001] The invention relates to arrangements and methods for adapting transport system parameters. The adaptation of the parameters is carried out using a power model of the transport system. Background technique [0002] In a transportation system such as an elevator system, some system parameters need to be identified for control and maintenance etc. Traditionally, system parameters are determined by calculation or testing. However, such methods come with problems that lead to inaccurate determinations. For example, errors in elevator system measurements will hamper elevator control. [0003] The specification EP1361999 describes the distribution of calls in an elevator group by using specific energy consumption files for each elevator car. [0004] Specification US5157228 describes a method for learning elevator control adjustment parameters. Contents of the invention [0005] The purpose of the present invention is to disclose an arrangement and a ...
