Intelligent outdoor lighting control system
First Claim
1. A method of controlling a lighting system having a plurality of lamps, wherein each lamp in the plurality of lamps is coupled to a controller module, the method comprising:
- sending a “
power on”
signal to the controller module, sending a “
lamp on”
command to the controller module to turn on at least one lamp associated with the controller module, determining start times for each lamp component to update operating logs, receiving lamp data from the controller module, comparing the lamp data to a predetermined range of lamp data values, and logging a fault condition if the lamp data is beyond the predetermined range of lamp data values.

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.
