Abstract:
An apparatus for retrofitting an elevator system to enable voice control includes a first main board installable within an elevator adjacent to an elevator button panel and two or more additional main boards installable on respective floors adjacent to respective elevator call panels, each of the main boards having a microphone circuit, a plurality of onboard output relays, and a processor operable to select an output relay in response to a voice command received by the microphone circuit and to output a signal to the selected output relay. One or more auxiliary output relay boards are installable within the elevator adjacent to the elevator button panel, each having a plurality of additional output relays selectable by the processor of the first main board. A controller area network (CAN) bus connects the first main board to the one or more auxiliary output relay boards.
