Abstract
Devices, systems, and methods for operating a building management system using a lighting control interface are described herein. One device includes an occupancy sensing component, a lighting control interface configured to connect the occupancy sensing device to a lighting control channel of a building, and a building management system (BMS) interface configured to connect the occupancy sensing device to a BMS channel of the building.
Claims14
An occupancy sensor, comprising:
- an occupancy sensing component;
- wherein the occupancy sensing component is at least one of an optical occupancy sensor, microwave occupancy sensor or an ultrasonic occupancy sensor;
- a lighting control interface included in the occupancy sensor and configured to connect the occupancy sensor directly to a digital addressable lighting interface (DALI) lighting control bus of a building without an intermediary;
- a building management system (BMS) interface included in the occupancy sensor and configured to connect the occupancy sensor directly to a BMS bus of the building without the intermediary;
- and
- a lighting control application included in the occupancy sensor and configured to translate data communicated, through the occupancy sensor, between the lighting control bus and the BMS bus;
- wherein the BMS interface includes at least one of an RS-232 port, a current loop interface, or an RS-485 port.
A system, comprising:
- a building management system (BMS) including a plurality of BMS devices of a building connected by a BMS bus;
- a lighting control system including:
- a plurality of lighting control system devices connected by a digital addressable lighting interface (DALI lighting control bus;
- and
- an occupancy sensor associated with the plurality of lighting control system devices, wherein the occupancy sensor includes:
- an occupancy sensing component;
- wherein the occupancy sensing component is at least one of an optical occupancy sensor, microwave occupancy sensor or an ultrasonic occupancy sensor;
- a BMS interface included in the occupancy sensor and configured to connect the occupancy sensor directly to the BMS bus of the BMS system without an intermediary;
- wherein the BMS interface includes at least one of an RS-232 port, a current loop interface, or an RS-485 port;
- a DALI lighting control interface included in the occupancy sensor and configured to connect the occupancy sensor directly to the lighting control bus of the building without the intermediary;
- and
- a lighting control application included in the occupancy sensor and configured to translate data communicated, through the occupancy sensor, between the lighting control system and the BMS system.
A method of operating a building management system using a lighting control interface, comprising:
- receiving a request made using a user interface of a building management system (BMS) device of a BMS bus of a building, the request associated with modifying a lighting setting in the building;
- receiving the request at an occupancy sensor via a BMS interface included in the occupancy sensor, wherein the occupancy sensor is directly connected to the BMS bus without an intermediary;
- translating, by the occupancy sensor the request from a BMS protocol to a lighting control protocol;
- and
- communicating, via a digital addressable lighting interface (DALI) lighting control interface included in the occupancy sensor directly connected to a DALI lighting control bus without the intermediary, the translated request from the occupancy sensor to a lighting control device of the lighting control bus.
