Abstract textA lighting monitor/control system for remote billboards uses a cellular network to provide utility power and light status information to a central controller, which in response provides control signals to individual remote billboard lighting controllers for setting operating parameters such as multiple on/off times, lighting power adjustments for individual billboards, and custom lighting schedules based upon geographic and environmental considerations. Battery back-up is provided in the event of utility power outage with automatic reversion to utility power when restored. Immediate notification of failure of utility power or of individual lamp or ballast failure is provided by SMS messaging formatted so as to minimize the number of messages and reduce communications costs. The monitor/control system is also adapted for use in remote power monitoring applications to automatically switch to standby power (generator) in the absence of primary power and to return to primary power when restored. |
