Networked light control system

摘要

LED light assemblies (20) are spaced over a geographical territory defined by a central dispatch of public service personnel operating in the geographical territory and are controlled by transmitting digital packets on a first radio frequency reserved for public safety personnel from a central transceiver (24) to repeaters (26) in the geographical territory and re-transmitting the digital packets on a different second frequency reserved for public safety personnel from the repeaters (26) to the light assemblies (20). In turn, the light assemblies (20) transmit digital radio signals on frequencies reserved for public safety personnel to the repeaters (26) for re-transmission to the central transceiver (24). A plurality of emergency signaling devices (36) transmit digital radio signals on the channels of frequencies reserved for public safety personnel to the light assemblies (20) to transmit a radio signal on the reserved frequencies to the central transceiver (24), a 9-1-1 alert or the like.

1. A system for transmitting and receiving radio signals to street light assemblies (20) including light emitting diodes (22) and spaced over a geographical territory defined by a central dispatch of public service personnel operating in the geographical territory, said system comprising;
a central system controller (52) for initiating the transmission and receipt of voice and tones and digital packets encoded with digital data on channels of radio frequencies reserved for public safety personnel in the geographical area, a central transceiver (24) interfacing said central system controller (52) transmitting and receiving said voice and said tones and said digital packets, a plurality of repeaters (26) for receiving said voice and said tones and said digital packets on a first radio frequency and re-transmitting said voice and said tones and said digital packets on a different second radio frequency, a plurality of personnel transceivers (28) located with public safety personnel for receiving said voice and said tones on said different second radio frequency and for transmitting said voice and said tones on said first radio frequency reserved for public safety personnel to said repeaters (26) for re-transmission to said central transceiver (24), a plurality of light assemblies (20) each including a plurality of light emitting diodes (22) and a microprocessor (34) for processing and storing digital data and each having a fixed digital address different from the fixed digital addresses of the other microprocessors (34) and a dynamic digital address for being assigned the same dynamic digital address as at least one other microprocessor (34) by said central system controller (52), each of said light assemblies (20) including a light transceiver (32) for receiving an LED radio signal having said digital packets encoded with digital data on said different second radio frequency initiated by said central system controller (52) for actuating the associated light assembly (20) independently of the other light assemblies (20) and for transmitting digital radio signals having digital packets encoded with digital data including said digital addresses of said microprocessor (34) on said first radio frequency to said repeaters (26) and ultimately to said central system controller (52), a plurality of emergency signaling devices (36) for broadcasting an emergency digital radio signal on said channels of radio frequencies to the nearest light transceivers (32) to actuate said microprocessors (34) for initiating an emergency LED radio signal on said channels of radio frequencies reserved for public safety personnel to said central system controller (52), each of said light transceivers (32) including a signal strength measurement device (50) for measuring the strength of said emergency digital radio signal and for generating emergency digital data representing said strength for transmission via said emergency LED radio signals to said repeaters (26) and ultimately to said central system controller (52), and said central system controller (52) including a signal strength voting algorithm program or device (64) for comparing and determining the one light transceiver (32) receiving the strongest emergency digital radio signal to provide the proximate geographical location in latitude and longitude of said emergency signaling device (36) broadcasting said emergency digital radio signal.
