## Abstract

Disclosed is an elevator system including an elevator car, a sensor operationally connected to the elevator car, and a smart device configured to: display collected sensor data, instruct the sensor to dynamically collect sensor data, displaying dynamically collected data, thereby dynamically illustrating trends in the sensed data. Further disclosed is a method of collecting sensor data in an elevator system using one or more features and elements of the disclosed elevator system, wherein the method includes display collected sensor data, instructing the sensor to dynamically collect sensor data, and displaying dynamically collected data, thereby dynamically illustrating trends in the sensed data.

## Claims

### Claim 1

An elevator system including
an elevator car,
a sensor secured to the elevator car, and
a smart device that is a mobile phone, wherein the mobile phone communicates with the sensor with wireless protocols, the smart device is configured to:
display, on the smart device, collected sensor data,
instruct the sensor to dynamically collect sensor data,
displaying dynamically collected data, thereby dynamically illustrating trends in the sensed data;
wherein
the collected data represents ride quality;
the smart device instructs the sensor to adjust sensitivity levels to provide sensor results within a predetermined bandwidth; and
wherein, responsive to analyzing the illustrated trends from the collected data, the smart device provides a scheduling calendar for scheduling elevator system diagnostics.

### Claim 2 (depends on 1)

The system of claim 1 wherein the smart device communicates with the sensor over a wireless ad hoc network.

### Claim 3 (depends on 1)

The system of claim 1 further comprising a controller for operatively communicating with the sensor over a local area network and communicating with the smart device over a personal area network.

### Claim 4 (depends on 3)

The system of claim 3 further comprising a telecommunications beacon for effecting communications with the smart device over the personal area network.

### Claim 5 (depends on 1)

The system of claim 1 wherein the controller is a building management system (BMS).

### Claim 6

A method of collecting data with an elevator system, the elevator system including an elevator car, a sensor secured to the elevator car, the method comprising:
display, on a smart device that is a mobile phone, wherein the mobile phone communicates with the sensor with wireless protocols, collected sensor data,
instructing, with the smart device, the sensor to dynamically collect sensor data,
displaying, on the smart device, dynamically collected data, thereby dynamically illustrating trends in the sensed data,
wherein
the collected data represents ride quality;
the smart device instructs the sensor to adjust sensitivity levels to provide sensor results within a predetermined bandwidth; and
wherein, responsive to analyzing the illustrated trends from the collected data, the smart device provides a scheduling calendar for scheduling elevator system diagnostics.

### Claim 7 (depends on 6)

The method of claim 6 wherein the smart device communicates with the sensor over a wireless ad hoc network.

### Claim 8 (depends on 6)

The method of claim 6 further comprising a controller for operatively communicating with the sensor over a local area network and communicating with the smart device over a personal area network.

### Claim 9 (depends on 8)

The method of claim 8 further comprising a telecommunications beacon for effecting communications with the smart device over the personal area network.

### Claim 10 (depends on 6)

The method of claim 6 wherein the controller is a building management system (BMS).
