Continuous quality monitoring of a conveyance system

A monitoring method comprising:

• generating, at an elevator system, one or more data streams describing a ride of the elevator system and comprising vibration data generated by a vibration sensor and audio data captured by a microphone;
• detecting a trigger event;
• triggering an active mode in response to the trigger event, wherein the vibration sensor measures vibrations during the active mode and the microphone captures audio during the active mode;
• transmitting, to an analytics system remote from the elevator system, sensor data based on the one or more data streams;
• and
• determining a ride quality of the elevator system, based on the sensor data;
• wherein the vibration sensor is configured to be placed in a sleep mode and the active mode, such that the vibration sensor measures vibrations during the active mode but not during the sleep mode, wherein the active mode of the vibration sensor is triggered in response to a first trigger event;
• wherein the microphone is configured to be placed in a sleep mode and the active mode, such that the microphone captures audio during the active mode but not during the sleep mode, wherein the active mode of the microphone is triggered in response to a second trigger event different than the first trigger event, the second trigger event being the detection of no passengers present in an elevator car.

A computer-program product for monitoring a elevator system, the computer-program product comprising a non-transitory computer-readable storage medium having program instructions embodied therewith, the program instructions executable by a processing unit to cause the processing unit to perform a method comprising:

• generating, at the elevator system, one or more data streams describing a ride of the elevator system and comprising of vibration data generated by a vibration sensor and audio data captured by a microphone;
• detecting a trigger event;
• triggering an active mode in response to the trigger event, wherein the vibration sensor measures vibrations during the active mode and the microphone captures audio during the active mode;
• transmitting, to an analytics system remote from the elevator system, sensor data based on the one or more data streams;
• and
• determining a ride quality of the elevator system, based on the sensor data;
• wherein the vibration sensor is configured to be placed in a sleep mode and the active mode, such that the vibration sensor measures vibrations during the active mode but not during the sleep mode, wherein the active mode of the vibration sensor is triggered in response to a first trigger event;
• wherein the microphone is configured to be placed in a sleep mode and the active mode, such that the microphone captures audio during the active mode but not during the sleep mode, wherein the active mode of the microphone is triggered in response to a second trigger event different than the first trigger event, the second trigger event being the detection of no passengers present in an elevator car.
