An elevator system includes an elevator car within an elevator hoistway; a camera; and an image analysis system in communication with the camera; the camera providing a reference image to the image analysis system; the camera providing a current image to the image analysis system; the image analysis system comparing the current image to the reference image to detect a difference between the current image to the reference image; the image analysis system initiating a maintenance notification in response to the comparing.

A method for determining a state of a system for transportation of passengers includes the steps of: receiving condition data of the system, the condition data being generated by a condition sensor adapted for sensing physical conditions of an equipment of the system; receiving environmental data of the system, the environmental data containing information on an influence of an environment of the system on the equipment and/or the condition sensor; weighting the condition data with the environmental data; and determining a state of the equipment based on the weighted condition data.

The present invention relates to a machinery brake for an elevator. The machinery brake comprises a frame part comprising an electromagnet and an armature part, wherein the machinery brake further comprising an inductive proximity sensor mounted to one of the following: the frame part, the armature part and a target mounted to the other of the following: the frame part, armature part. The inductive proximity sensor and the target are mounted with respect to each other so that in a normal state of the machinery brake the target resides within an operational area of the inductive proximity sensor and in an abnormal state of the machinery brake the target resides at least partly outside the operational area of the inductive proximity sensor. The invention also relates to a method therein.

A method of wear detection of a coated belt or rope includes connecting a wear detection unit to one or more monitoring strands and/or cords of a coated belt or rope. The coated belt or rope includes one or more baseline strands and/or cords exhibiting a first change in electrical resistance as a function of bending cycles of the belt or rope and one or more monitoring strands and/or cords exhibiting a second change in electrical resistance as a function of bending cycles of the belt or rope, greater than the first change in electrical resistance. An electrical resistance of the one or more monitoring strands and/or cords is measured via the wear detection unit. Using at least the measured electrical resistance of the one or more monitoring strands and/or cords, a wear condition of the belt or rope is determined.

Methods and systems for reporting issues in an elevator system are provided. The reporting system includes a display located within an elevator car, an input device configured to receive input from a passenger within the elevator car, and a computing system having a processor and a memory, the computing system configured to generate a user interface on the display and configured to receive input from the input device, wherein the memory includes a list of possible issues related to the elevator car. The computing system is configured to generate a user report based on the received input, and transmit the user report to a remote location.

An elevator system (100) includes an elevator drive system (101) including a tension member (103) supporting an elevator car (106) under tension and a monitoring system (102). The monitoring system includes a vibration sensor (111) for detecting vibration of at least one of the tension member and the elevator car and an analysis unit (112) for determining a level of wear and life of the tension member based on the vibration of the tension member detected by the vibration sensor.

A drive engine arrangement for an elevator system includes a drive engine for driving suspension traction media for displacing an elevator car, a fan for generating a fluid flow for cooling the drive engine and a fluid flow sensor. The fluid flow sensor senses the fluid flow generated by the fan. Accordingly, using the fluid flow sensor, it can be determined whether or not the fan is currently operating. By e.g. comparing the fan's behavior with previous operation patterns and/or by additionally measuring a temperature of the drive engine with a temperature sensor, it can be monitored whether the fan is operating correctly or whether e.g. cooling requirements may be compromised due to a malfunction of the fan. Such monitoring can be performed remotely and/or automatically.

A method for operating an elevator control system for controlling and monitoring the movements of at least one elevator car when the elevator car approaches individual floors in a building, and in the process stops at a respective floor in a prescribed stopping position, the method including, in conjunction with a floor stop, determining an overall error in the form of a deviation between an actual position of the elevator car and a position of the elevator car assumed as the current position. The elevator control system generates service signals based on a statistical acquisition of several values for the overall error, and/or wherein the overall error is used to ascertain a derivative value, which is taken into account along with the current or stopping position during a comparison between the current position and stopping position performed by the elevator control system for approaching the respective stopping position.
