Problems solved by technology
The disadvantage of this prior art solution is that the information about the failure of the elevator is only provided to the elevator service unit when the elevator has come to a complete stop
Therefore, it is already too late to take any preventive measures and the problem must be solved immediately because the elevator is not operational during the time it is not repaired

Embodiment Construction
[0025] Elevator usage may be different on different days or at different times of the day. For example, in an office building, elevators may be heavily used during the working day, and especially during the morning and afternoon, when people come to and leave the office. For example, between 7:30 am and 9:00 am and / or between 3:00 pm and 6:00 pm. On the other hand, for example, during weekends and / or when the office building is closed, there may be little use of the elevator. Also, during the same time period, elevator usage may be very similar to the same elevator usage on the same day in the previous week.
[0026] Any change in elevator usage may indicate a problem with the elevator's operation. The problem may be a misoperation of the elevator. Some non-limiting examples of elevator misoperation may be accidents, malfunctions, breakdowns, wear and tear. Alternatively or additionally, a significant change in usage itself can provide important information to the building...

The invention relates to an elevator system (100) for observing malfunctions. The elevator system includes an observation unit (106) and a processing unit (106). The observation unit (106) is configured to obtain data representing the movement of the elevator car (102) during a predetermined time interval and to transmit the obtained data to the processing unit (108). The processing unit (108) is configured to receive and store data representing movement of the elevator car (102), generate at least one statistical parameter from the received data, compare the at least one generated statistical parameter with at least one previously stored The statistical parameters are compared and a signal indicative of a misoperation is generated in response to detecting that at least one generated statistical parameter deviates from a corresponding previously stored statistical parameter by more than a predetermined limit. The invention also relates to a method for observing malfunctions.
Description
technical field [0001] The present invention generally relates to the technical field of elevator technology. In particular, the invention relates to observing the condition of elevators. Background technique [0002] Typically, an elevator includes an elevator car and an elevator configured to drive the elevator car in a hoistway between landings. Some misoperations, such as failure or failure, may occur during elevator operation. In most cases, when a misoperation occurs, the operation (eg, movement) of the elevator car stops, and the operation of the elevator may not continue until the elevator is repaired. Usually, the user of the elevator is the first person to notice a malfunction or failure and to notify it to an elevator service unit such as an attendant, a service center, a service company or similar. Alternatively or additionally, an automatic notification, for example in the form of at least one fault code, may be passed directly from the elevator control syste...
