Abstract
An elevator rope monitoring device includes at least one source of electromagnetic radiation for emitting a radiation beam, at least one sensor for receiving at least part of an emitted radiation beam, a control unit for detecting an abnormality of an elevator rope arranged to travel between the at least one source of electromagnetic radiation and the at least one sensor by analyzing measurement data received from the at least one sensor. A method, a computer program product and an elevator system are also disclosed.
Claims20
An elevator rope monitoring device comprising:
- at least one source of electromagnetic radiation for emitting a radiation beam;
- at least one sensor for receiving at least part of the emitted radiation beam;
- and
- a control unit for detecting an abnormality of an elevator rope arranged to travel between the at least one source of electromagnetic radiation and the at least one sensor by analyzing measurement data received from the at least one sensor.
A method for monitoring an elevator rope, the method comprising:
- generating, by a control unit of an elevator rope monitoring device, a control signal to at least one source of electromagnetic radiation for emitting a radiation beam;
- receiving, by the control unit of the elevator rope monitoring device, measurement data from at least one sensor receiving at least part of the emitted radiation beam;
- and
- detecting, by the control unit of the elevator rope monitoring device, an abnormality of an elevator rope arranged to travel between the at least one source of electromagnetic radiation and the at least one sensor by analyzing data received from the at least one sensor.
