Abstract
A system and method is presented for hands-free operation of elevator using a smart phone or like device to display one or more colours that are read by a colour-detection device mounted in an elevator cabin and at each elevator landing. Different colours can be displayed by the smart phone or like device and detected by the colour-detection device where different can represent different commands to operate the elevator.
Claims18
A system for hands-free control of a control panel of an elevator, the system comprising:
- a) a colour detector configured for detecting a unique colour code comprised of a plurality of colours, the colour detector further configured to generate a first signal in response to the colour detector detecting the unique colour code;
- b) a microcontroller operatively coupled to the colour detector, the microcontroller configured to receive and decode the first signal to generate a predetermined output signal in response to the unique colour code, the microcontroller further configured to generate a plurality of unique predetermined output signals, one for each of the unique combination of the plurality of colours;
- and
- c) a plurality of relays operatively coupled to the microcontroller, wherein the system further comprises at least one relay for each of the plurality of the unique output signals, each of the plurality of relays configured to be operatively coupled to at least one button disposed on the control panel.
