Intelligent outdoor lighting control system
First Claim
1. An outdoor lighting control system for a string of outdoor illumination lamps disposed at various locations along an outdoor lighting system comprising:
- for each of plural lamp locations in the string, a controller module comprising input means for receiving electric power input and output means for supplying electric power to the remainder of the string, each of said plural lamp locations further comprising one or more outdoor illumination lamps;
each controller module comprising a first switching means for switching the electric power input to deliver current to the one or more outdoor illumination lamps at the controller module'"'"'s location, a second switching means for switching electric input power from the controller module'"'"'s input means to the controller module'"'"'s output means in response to receipt of electric power input at the controller module'"'"'s input means, a electronic control unit for controlling the first switching means and the second switching means, and a first current sensing means for sensing current flowing through its first switching means and a second current sensing means for sensing current flowing through its second switching means.

Abstract
A new and improved outdoor lighting control system for an outdoor lighting system network for automatically sensing, conveying, and recording data relevant to the operation of the lighting system network so that both control and maintenance can be performed more efficiently. At each of plural lamp locations in the network, there is a controller module that receives electric power input and that supplies electric power to the remaining lamp locations. Each controller module has a first relay to deliver current to one or more outdoor illumination lamps at the controller module'"'"'s location, and a second relay for switching electric power on to a succeeding lamp location. A first current sensor monitors current to the lamps at each lamp location, and a second current sensor monitors current to the remaining locations. The network'"'"'s power lines form portions of a bi-directional data link via which data is transmitted from each controller module to a command station, and vice versa.
