Abstract
The present invention presents a method and a system for the positioning of the elevator car and the door of the elevator in the condition monitoring system. In the method the accelerations of the elevator car and the door of the elevator are measured with sensors. By integrating the acceleration information two times in relation to time the position information is determined. When the condition monitoring system detects a fault, forecasts a malfunction occurring in the future or detects a significant change in the operation of the elevator or in the measuring signals related to the elevator, it is possible to attach to this information the location of the fault or event i.e. the position of the elevator or the position of a door of a certain floor level on the slide path. The position information can be synchronized to a separate reference point by means of a positioned switch by making an adjustment to the position information at the reference point. The measuring error caused by the misalignment of the position of the acceleration sensor is compensated for either with electronics or using a program.
