98 Controlling a Street Lighting Network
• Weekdays. A daily schedule turns on the lights at the start of the
morning commute hour, turns them off for the daylight hours, turns them
on again for the evening commute hour, and dims them at the end of the
evening commute hour.
• Weekends. A weekly schedule that turns on the lights at sundown and
turns them off at sunrise.
You would create exception schedules for holidays. The holiday exception
schedules would have the same behavior as the weekend schedule.
Creating the Weekday Schedule
The weekday schedule shown in Figure 11 uses the following events, which
occur Monday through Friday:
• An ON_100 event that turns on the lights to 100% at the start of the
morning commute hour. This event occurs at one hour before sunrise.
• An OFF event that turns the lights off during the daylight hours. This
event occurs at 09:00 AM.
• An ON_100 event that turns on the lights to 100% at the start of the
evening commute hour. This event occurs at one hour before sunset.
• An ON_60 event that dims the lights at the end of the evening commute
hour. The lights remain at this level for the rest of the night. This event
occurs at 20:00 (8:00 PM).
