20080230326 | Condition monitoring system - The present invention relates to an elevator condition monitoring system, which comprises at least a control unit ( | 09-25-2008 |
20090166133 | Positioning Method in an Elevator System - 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. | 07-02-2009 |
20090218176 | CONDITION MONITORING METHOD - Method for the condition monitoring of the safety switches of the safety circuit of an elevator. Inferences can be made about the condition of a safety switch by measuring and examining the current of the safety circuit of the elevator after the state of the safety circuit has changed. The current signal is filtered, after which the amount of interference caused by contact malfunctions of the switch is determined from it. Based on the amount of interference it is possible to determine in what condition the switch is. | 09-03-2009 |
20090218177 | ELEVATOR SYSTEM - The present invention discloses a method, a device, a computer program and a system for detecting the arrival in the elevator car/departure from the elevator car of elevator passengers. In the method the vertical acceleration values of the elevator car are received from the acceleration sensor and the passengers arriving in the elevator car and/or leaving the elevator car are detected on the basis of the vertical acceleration measurements of the acceleration sensor. | 09-03-2009 |
20100276230 | ADAPTATION OF TRANSPORT SYSTEM PARAMETERS - 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 ( | 11-04-2010 |
20140339024 | ARRANGEMENT AND METHOD FOR MONITORING CONDITION OF AUTOMATIC DOOR - An arrangement and a method for monitoring the operational condition of an automatic door in an elevator, particularly a passenger and/or goods elevator, or in a building, the arrangement includes an automatic door which includes one or more door leaves, which slide horizontally in their location, a door operator, which includes a door motor and a door mechanism for moving the door leaf horizontally in its location, a closing device for closing the automatic door, a control system for the door operator for controlling the door motor, a device configured to define the operational condition of the closing device and the door mechanism of the automatic door, the device configured to define the operational condition of the closing device and the door mechanism of the automatic door includes a mechanism configured to determine the mechanical energy of the shaft in the door motor of the automatic door during an operating cycle. | 11-20-2014 |
20150019182 | OBTAINING PARAMETERS OF A TRANSPORT SYSTEM - The invention refers to a method for obtaining the system parameters of a transport system, particularly an elevator, in which method
