Planning for the Street Lighting Solution
Scheduling
Figure 9. RF/RF Repeating
The Segment Controller includes an Event Scheduler application that you can
use to schedule events. Thus, for example, you can schedule luminaires to turn
on at sundown, dim at the end of the evening rush hour, brighten at the start of
the morning rush hour, and then turn off at sunrise. In general, you would not
define an event schedule for CRD 3000 Street Light Bridge modules (they should
run continuously).
See Chapter 6, Controlling a Street Lighting Network, for more information about
scheduling.
Device and Network Recovery Planning
The CRD 3000 Street Light Bridge module has a watchdog mechanism that
covers the main processor, the Smart Transceiver, and the radio communication
chip. That is, if LonTalk (ISO/IEC 14908-3) communications are lost, the Smart
Transceiver resets; if the radio communications are lost, the radio communication
chip resets.
Figure 10 shows a simple street lighting network with two CRD 3000 Street
Light Bridge modules. This section considers two recovery scenarios: loss of SLB
A or loss of SLB B. For any extended outage (generally longer than 15 minutes),
