Method and apparatus for maintaining device information in a lighting control system
View Patent ↗The invention regards a system and method for using a handheld programming device to configure a lighting control system wirelessly. In one embodiment, at least one device configured with a processing section is installed in the lighting control system. A communications receiver that is operable to receive a signal from the handheld programming device is also installed in the lighting control system, wherein the signal includes an instruction for configuring the lighting control system. Further, the signal is wirelessly sent from the handheld programming device to the communications receiver, and the instruction is transmitted from the communications receiver to a device in the system. The instruction functions to configure the lighting control system.
1. A method for maintaining information representing devices installed in a lighting control system, the system comprising a plurality of ballasts and a bus supply linked together by a communication bus, the bus supply providing a DC voltage to the communication bus, the method comprising:
wirelessly transmitting ballast configuration information from a handheld programmer, wherein the ballast configuration information represents one or more configuration settings of one or more respective ballasts;
storing in each of the plurality of ballasts respective ballast configuration information;
transmitting the respective ballast configuration information to the bus supply via the communication bus; and
storing in the bus supply the respective ballast configuration information for each of the ballasts.
2. The method of claim 1 , wherein the configuration setting represents at least one of a high end trim, a low end trim, a fade time, a ballast burn-in state, an emergency level intensity setting, an intensity level to operate a ballast in response to a photosensor registering a light input, an intensity level to operate a ballast in response to an occupancy sensor registering an occupied or an unoccupied status, a time-out value, and an intensity level to operate a ballast in response to a contact closure input registering a closed status or an open status.
3. The method of claim 1 , further comprising:
storing information representing a correlation of at least one wall control with at least one ballast,
wherein the information for the wall control is stored in the bus supply, the at least one ballast, or both.
4. The method of claim 1 , further comprising:
storing information representing ballast light intensity levels configured in association with each respective ballast's location within a room,
wherein the information representing ballast light intensity levels configured in association with each respective ballast's location within a room is stored in the bus supply, a respective ballast, or both.
5. The method of claim 1 , further comprising:
storing information representing a correlation of at least one sensor device with at least one ballast,
wherein the information for the sensor device is stored in the bus supply, the at least one ballast, or both.
6. The method of claim 5 , wherein information for the at least one ballast and a sensor device connected to the ballast is stored in the ballast.
7. The method of claim 5 wherein the information for the sensor device is stored in the bus supply and the at least one ballast.
8. A lighting control system comprising:
a handheld programmer operable to wirelessly transmit ballast configuration information, wherein the ballast configuration information represents one or more configuration settings of one or more respective ballasts;
a plurality of ballasts coupled to a communication bus, each of the plurality of ballasts operable to store respective ballast configuration information; and
a bus supply coupled to the communication bus and operable to provide a DC voltage to the communication bus;
wherein the bus supply is operable to receive respective ballast configuration information via the communication bus and to store the respective ballast configuration information for each of the ballasts.
9. The lighting control system of claim 8 , wherein the respective configuration setting of the respective ballasts represents at least one of a high end trim, a low end trim, a fade time, a ballast burn-in state, an emergency level intensity setting, an intensity level to operate a ballast in response to a photosensor registering a light input, an intensity level to operate a ballast in response to an occupancy sensor registering an occupied or an unoccupied status, a time-out value, and an intensity level to operate a ballast in response to a contact closure input registering a closed status or an open status.
10. The lighting control system of claim 8 , further comprising:
a sensor device connected to at least one ballast,
wherein the ballast is operable to store information representing a correlation of the sensor device and the at least one ballast.
11. The lighting control system of claim 10 , wherein the bus supply is operable to store information representing the correlation of the sensor device and the at least one ballast.
12. The lighting control system of claim 8 , further comprising:
a wall control connected to at least one ballast,
wherein the ballast is operable to store information representing a correlation of the wall control and the at least one ballast.
13. The lighting control system of claim 12 , wherein the bus supply is operable to store information representing the correlation of the wall control and the at least one ballast.
