摘要:
A policy-based OLN (outdoor lighting network) light management system including a central control apparatus (40); lighting unit control apparatus (50); a communication system (60) operably connecting the central control apparatus (40) and the lighting unit control apparatus (50); and a repository (70) in communication with the central control apparatus (40), the repository (70) being operable to store an OLN policy. The central control apparatus (40) is operable to: receive a policy; check the policy for consistency against the OLN policy; determine attributes and configuration commands for each of the lighting unit control apparatus (50) in accordance with the policy when the policy is consistent with the OLN policy; and communicate the attributes and the configuration commands for each of the lighting unit control apparatus (50) to a corresponding one of the lighting unit control apparatus (50).

摘要:
A method (300) for enabling self-coexistence of devices in a flexible wireless system (200) that includes first and second wireless networks sharing a frequency band. The method includes discovering a second device operable in the second wireless network that overlaps with the first wireless network (S310); reporting the discovered second device to a first device operable in the first wireless network (S320); determining if an adjustment is needed between a first beacon period of the first device and a second beacon period of the second device (S330); and adjusting a first beacon period start time (BPST) of the first device with a second BPST of the second device (S370) if the adjustment is needed.
摘要:
Channel access time slots are reserved in a wireless network employing a flexible medium access control (MAC) protocol. At least a type and a mode of the channel reservation are determined (S310). A reservation request frame is generated (S320) based on the determined type and mode of the channel reservation. The reservation request frame is sent to a reservation proxy device (S330). In response to the reservation request frame, a reservation response frame is received from the reservation proxy device (220-RP). Usage of an allocated time slot is announced if a channel reservation request is confirmed in the reservation response frame (S382).
摘要:
A lighting system (100) including at least one controller (102) and a memory (104) containing program portions which configure the controller (102) to obtain weather forecast information including one or more of current and expected weather conditions over a period of time; determine one or more lighting settings based upon the weather forecast information; form lighting setting information in accordance with the determined lighting settings; and transmit the lighting setting information. The system (100) may include an illumination source (106) to provide illumination in accordance with the lighting setting information The system may change characteristics (e.g., illumination pattern, illumination intensity, illumination spectrum, illumination polarization,) of the illuminated source (106). The process may form lighting setting information to control one or more filters (130) in accordance with a desired lighting setting.
摘要:
An OLN lighting requirements generation system and method including a lighting requirements generation system for an outdoor lighting network (OLN, 90) having lighting units (82), the system having a central control apparatus (40); a plurality of lighting unit control apparatus (50); and a communication system (60) operably connecting the central control apparatus (40) and the lighting unit control apparatus (50). The central control apparatus (40) is operable to: acquire location-based data; define clusters from the location-based data; define lighting requirements for each of the clusters; associate the lighting units (82) to the clusters from location information for the lighting units; map the lighting units (82) to the lighting requirements; and implement the lighting requirements of the clusters associated with each of the lighting units (82).
摘要:
Light management system for an outdoor lighting network (OLN) having lighting units, the system including a central control apparatus (40); lighting unit control apparatus (50); and a communication system (60). The central control apparatus (40) is operable to receive a configuration request; receive optimization objectives/constraints; identify the lighting units operably connected to the plurality of lighting unit control apparatus (50) associated with the configuration request; determine whether at least one of lighting requirements, illuminance model, and cost model have changed; update the lighting requirements, the illuminance and the cost model when at least one of the lighting requirements, the illuminance model, and the cost model have changed; optimize operation of the identified lighting units as a function of the optimization objectives/constraints, the lighting requirements, the illuminance and the cost model; and send an operation instruction to the lighting control apparatus (50).
