Wireless communication based safer street lamp control system
First Claim
1. A street lamp control system disposed in a region divided into a plurality of areas, the street lamp control system comprising:
- a plurality of street lamps being disposed in each of the plurality of areas with the street lamps within each of the areas being serially connected to each other by power lines providing power to each street lamp;
a plurality of distribution panels each installed at a center of each corresponding area, the distribution panel including power source control switching circuits respectively controlling the power provided to each street lamp within the corresponding area; and
a plurality of sensors coupled to different corresponding ones of the distribution panels and disposed to respond to an abnormal state occurring to a street lamp disposed in a first area having a first distribution panel, the power source control switching circuits controlling the power provided to the street lamp having the abnormal state by cutting off the power provided to the street lamp having the abnormal state, and street lamps disposed in the first area which are different from the street lamp having the abnormal state and are disconnected from power provided by the first distribution panel being provided by power supplied by a second distribution panel disposed within a second area neighboring the first area.

Abstract
Disclosed is a street lamp control system, which cuts off power sources only around an abnormal street lamp where an electric leakage or dangerous situation occurs and allows the rest street lamps to be kept being turned on. The street lamp control system is positioned in a region divided by a plurality of areas where a predetermined number of street lamps are installed. A distribution panel is installed in each center of the areas, and includes two power source control switching circuits for controlling right and left power sources of the corresponding areas. The power source control switching circuit of the corresponding distribution panel turns off the right and left street lamps including the corresponding street lamp when an abnormal state is sensed on a specific street lamp of a specific area, and a power is supplied to the right and left street lamps to be turned on excluding the abnormal street lamp.

4. A street lamp control system for remote-controlling street lamps using low power radio communication, comprising:
-
a street lamp light controller installed in a street lamp pole, and exchanging information with a local controller and simultaneously controlling a street lamp installed at the street lamp pole in accordance with an individual control command and a group control command transmitted from the local controller; the local controller exchanging information and a control signal with street lamp light controllers each installed at a corresponding street lamp pole to control the corresponding street lamp in individual and group ways; a central control center controlling the local controller in order to enable the corresponding street lamp to be controlled in the group and individual ways; and the local controller and the street lamp light controller being connected in a low power radio communication protocol, ZigBee, and the local controller and the central control center being connected via a bidirectional radio communication network. - View Dependent Claims (5, 6, 7, 8)

9. A street lamp control system, comprising:
-
a plurality of street lamps; a plurality of distribution panels discretely installed among the plurality of street lamps, a predetermined number of street lamps disposed between two neighboring distribution panels, and the plurality of street lamps serially electrically connected to each other by power lines each providing power to a corresponding street lamp; and a plurality of sensors coupled to corresponding ones of the distribution panels and disposed to respond to an abnormal state occurring to a street lamp, one of distribution panels neighboring the street lamp having the abnormal state disconnecting the power provided to the street lamp having the abnormal state, and the other distribution panel neighboring the street lamp providing power to street lamps which are different from the street lamp having the abnormal state and are disconnected from power provided from the one of distribution panel neighboring the street lamp.
