Streetlight monitoring and control system
DIMONOFF INC, PUBLIC LIGHT MONITORING AND CONTROL SYSTEM
Powerline communication technology specifications:
- Carrier Type ASK and Very robust narrowband FSK modulation
- Complete Media Access Control (MAC) logic
- CSMA/CD type collision detection and resolution
- Carrier Frequency: 262 kHz
- Error detection (CRC 16) for every transmission
- High-efficiency Forward Error Correction (FEC)
XB technology (radio-frequency): Specifications:
- 2.4Ghz Automesh 802.15.4 ISM rated
- range up to 1mile (1.6km) LOS

Typical Pole-Lamp module functions (REL-MON-20-VVV)
- Individual serial number per relay
- Capacity to create 32767 groups with 15 levels of subgroups plus capacity to assign 65534 logical addresses per group.
- ON/OFF control
- Lamp Capacitor/ballast status (based on power factor measured by the relay)
- Poles fuses status (declared defective if no current is drawn by load) existing fuses need to be installed between the relay and the lamp.
- Usage timers (2 timers, 1 for ballast and 1 for lamp, measured by the relay)
- Cycling detection, prevention and alarms
- Pole door open/close (based on magnet contact or mechanical switch sensor provided by third party)
- Electrical measurements: Current (A), Voltage (V), Power (W), Power Factor, Temperature (C) (measured by the relay), it is possible to identify leakage or failure based on reference parameters.
- HI-LO Bi-Level dimming module with dual-capacitor circuit: Lights dimming control: to save 30% or more of energy and extend lamp and ballast life, we can schedule the dimming to reduce the light power during predefine hours or to reduce energy requirements during peak periods. Module provides required start time protection to HI level to prevent Lamps and ballast damage. Relay is provided with two impendent output wired to connect to a dual-capacitor module. Note additional installation may be required to replace existing capacitors and arrange wiring accordingly.
- Options (not included in current proposal)
1. Ground fault detection circuit
2. Pole tilt detection requires an additional sensor
3. Wire theft alarm (not functional if power is out)
For Substations (SS) Remote Terminal Units (RTU)
- SS Alarms (6 inputs or outputs available via INT-MIO-U6)
-
SS doors open/close status (based on magnet contact or mechanical switch sensor to beprovided by 3rd party)
-
Distribution panels door open (based on magnet contact or mechanical switch sensor tobe provided by 3rd party)
-
Circuit breakers control: MV breakers control by 1 low-voltage digital output to control 3rdparty supplied relay (Via INT-MIO-U6) Note: in order for the pole relays to operate, MV breakers must be closed at all time and all feeds need to remain energized.
