Abstract

A conveyance system includes a local gateway configured to communicate with a remote system over a communications network; at least one module in communication with the local gateway; the at least one module including a processor configured to perform local processing of data at the at least one module.

First claim

What is claimed is:

1. A conveyance system comprising:
an elevator car;
a local gateway configured to communicate with a remote system over a communications network;
at least one module in communication with the local gateway;
the at least one module including at least one of:
a sensor module mounted to the elevator car, the sensor module including a sensor configured to detect a condition at the elevator car and a processor configured to perform local processing of data from the sensor at the sensor module, the local processing comprising determining car location or determining faults;
a car level module mounted to the elevator car, the car level module including a location sensor configured to detect a location of the elevator car relative to a landing and a processor configured to perform local processing of data from the location sensor at the car level module, the local processing comprising computing a distance and direction of car movement needed to level the elevator car with a landing;
a light presence module mounted to the elevator car, the light presence module including a light sensor configured to detect a light level in the elevator car and a processor configured to perform local processing of data from the light sensor at the light presence module, the local processing comprising determining if a sensed light level is greater than a threshold; and
an operating panel module mounted to the elevator car, the operating panel module including a user interface and a processor configured to perform local processing of data from the user interface at the operating panel module, the local processing comprising processing an input into a format usable by a system controller.

2. The conveyance system of claim 1 , wherein the condition detected by the sensor of the sensor module includes at least one of acceleration, air pressure and sound.

3. The conveyance system of claim 1 , further comprising:
a voice module mounted to the elevator car, the voice module including a microphone and a speaker.

4. The conveyance system of claim 3 , wherein the voice module is configured provide at least one of uni-directional and bi-directional voice communication at the elevator car.

5. The conveyance system of claim 1 , wherein the user interface is configured to receive a destination floor from a passenger.

6. The conveyance system of claim 1 , wherein the user interface includes an audio/video unit.

7. The conveyance system of claim 1 , further comprising:
a processing module mounted to the elevator car, the processing module including a wireless interface and a wired interface.

8. The conveyance system of claim 7 , wherein the wireless interface provides communication between the processing module and a second module of the at least one module.

9. The conveyance system of claim 8 , wherein the processing module provides local processing of data received from the second module to generate processed data.

10. The conveyance system of claim 8 , wherein the processing module is configured to provide the processed data to the local gateway.

11. The conveyance system of claim 7 , wherein the wired interface is configured to communicate over an elevator system bus.

12. The conveyance system of claim 7 , wherein the wired interface is configured to provide power to the processing module.

13. The conveyance system of claim 7 , wherein the at least one module includes the car level module, the light presence module, the sensor module, and the operating panel module.

14. The conveyance system of claim 1 wherein the at least one module includes a power source.

15. The conveyance system of claim 14 wherein the power sources includes at least one of a battery, a power line, an inductive power receiver, a regenerative power source and an energy harvesting device.

16. The conveyance system of claim 1 , wherein the at least one module includes at least two of the car level module, the light presence module, the sensor module, and the operating panel module.
