## Abstract

A method of monitoring a conveyance apparatus within a conveyance system including: detecting a plurality of accelerations of the conveyance apparatus; determining a number of maximum accelerations of the plurality of accelerations that are above a threshold acceleration; determining that the number of maximum accelerations exceeds a threshold number of maximum accelerations within a threshold time period; and determining a health level of the conveyance system in response to the number of maximum accelerations within the threshold time period.

## Claims

### Claim 1

A method of monitoring a conveyance apparatus within a conveyance system, the method comprising:
detecting a plurality of accelerations of the conveyance apparatus;
determining a number of maximum accelerations of the plurality of accelerations that are above a threshold acceleration;
determining that the number of maximum accelerations exceeds a threshold number of maximum accelerations within a threshold time period; and
determining a health level of the conveyance system in response to the number of maximum accelerations within the threshold time period.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
activating an alert on a mobile device indicating the health level for the conveyance system.

### Claim 3 (depends on 1)

The method of claim 1, further comprising:
receiving a selection input on a mobile device, the selection input indicating a mechanic feedback regarding the health level of the conveyance system.

### Claim 4 (depends on 3)

The method of claim 3, further comprising:
adjusting the threshold number of maximum accelerations within the threshold time period in response to the mechanic feedback.

### Claim 5 (depends on 3)

The method of claim 3, further comprising:
adjusting the threshold time period in response to the mechanic feedback.

### Claim 6 (depends on 3)

The method of claim 3, further comprising:
adjusting the threshold acceleration in response to the mechanic feedback.

### Claim 7 (depends on 3)

The method of claim 3, further comprising:
adjusting the health level of the conveyance system to an adjusted health level in response to the mechanic feedback.

### Claim 8 (depends on 1)

The method of claim 1, further comprising:
displaying the health level for the conveyance system on a display device of a mobile device.

### Claim 9 (depends on 3)

The method of claim 3, wherein receiving the selection input on the mobile device further comprises:
displaying a plurality of mechanic feedback options; and
receiving a selection input on the mobile device selecting one of the plurality of mechanic feedback options indicating the mechanic feedback.

### Claim 10 (depends on 1)

The method of claim 1, further comprising:
identifying a root cause that caused the number of maximum accelerations to exceed the threshold number of maximum accelerations within the threshold time period.

### Claim 11 (depends on 3)

The method of claim 3, wherein the mechanic feedback identifies a root cause that caused the number of maximum accelerations to exceed the threshold number of maximum accelerations within the threshold time period.

### Claim 12 (depends on 10)

The method of claim 10, further comprising:
receiving a selection input on a mobile device, the selection input indicating a mechanic feedback regarding the health level of the conveyance system,
determining whether the root cause was correct or incorrect in response to the mechanic feedback.

### Claim 13 (depends on 1)

The method of claim 1, wherein the plurality of accelerations of the conveyance apparatus comprise accelerations along three axis.

### Claim 14 (depends on 1)

The method of claim 1, wherein the conveyance system is an elevator system and the conveyance apparatus is an elevator car.

### Claim 15 (depends on 14)

The method of claim 14, wherein the plurality of accelerations of the conveyance apparatus comprise accelerations of the elevator car.

### Claim 16 (depends on 14)

The method of claim 14, wherein the plurality of accelerations of the conveyance apparatus comprise accelerations of an elevator door of the elevator car.

### Claim 17

A system for monitoring a conveyance apparatus within a conveyance system, the system comprising:
a processor; and
a memory comprising computer-executable instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising:
detecting a plurality of accelerations of the conveyance apparatus;
determining a number of maximum accelerations of the plurality of accelerations that are above a threshold acceleration;
determining that the number of maximum accelerations exceeds a threshold number of maximum accelerations within a threshold time period; and
determining a health level of the conveyance system in response to the number of maximum accelerations within the threshold time period.

### Claim 18

A computer program product embodied on a non-transitory computer readable medium, the computer program product including instructions that, when executed by a processor, cause the processor to perform operations comprising:
detecting a plurality of accelerations of the conveyance apparatus;
determining a number of maximum accelerations of the plurality of accelerations that are above a threshold acceleration;
determining that the number of maximum accelerations exceeds a threshold number of maximum accelerations within a threshold time period; and
determining a health level of the conveyance system in response to the number of maximum accelerations within the threshold time period.
