Abstract
In accordance with at least some embodiments, a process for determining the safety of an elevator may be implemented to collect, by an acceleration sensor, an operational measurement of the elevator in operation, wherein the operational measurement includes a velocity measurement of the elevator. The process may be implemented to determine, by a processor, an operational status of the elevator by evaluating the operational measurement. The process may further be implemented to generate, by the processor, a warning signal when the operational status indicates that the elevator is operating abnormally.
Claims20
A method for determining the safety of an elevator, comprising:
- collecting, by an acceleration sensor, an operational measurement of the elevator, wherein the operational measurement comprises a velocity measurement of the elevator;
- determining, by a processor, an operational mode of the elevator by evaluating the operational measurement, wherein the operational mode indicates whether the elevator is loaded or unloaded;
- determining, by the processor, an operational status of the elevator by evaluating the operational measurement and the operational mode, wherein the operational status indicates whether the elevator is operating normally or abnormally;
- and
- generating, by the processor, a warning signal when the operational status indicates that the elevator is operating abnormally.
A method for determining the safety of an elevator, comprising:
- collecting, by an acceleration sensor, a velocity measurement of the elevator as the elevator is in operation;
- collecting, by a noise sensor, a noise measurement of the elevator as the elevator is in operation;
- determining, by the processor, an operational mode of the elevator based on the velocity measurement, wherein the operational mode indicates whether the elevator is loaded or unloaded;
- and
- determining, by a processor, an operational status of the elevator by comparing the velocity measurement with a baseline velocity measurement associated with the operational mode and comparing the noise measurement with a baseline noise measurement associated with the operational mode, wherein the operational status indicates whether the elevator is operating normally or abnormally.
A system configured to determine the safety of an elevator, comprising:
- an acceleration sensor to collect a velocity measurement of the elevator;
- a microphone to collect a noise measurement of the elevator;
- and
- a processor coupled with the acceleration sensor and the microphone, the processor configured
- to determine an operational mode of the elevator from the velocity measurement, wherein the operational mode indicates whether the elevator is loaded or unloaded,
- to determine an operational status of the elevator from the operational mode, the velocity measurement and the noise measurement, wherein the operational status indicates whether the elevator is operating normally or abnormally, and
- to generate a warning signal upon a determination that the operational status indicates that the elevator is operating abnormally.
