smart city street light infrastructure control monitoring system

Detailed of the PLC & LoRa Technology showing on 93km Shen Zhen Outer Ring Expressway Street Lights & Tunnel Light Groups:

NEMA Based Street Lighting Controller

I. INTRODUCE

CH-SLC910 Smart Single Lighting Controller is an important part of Intelligent Lighting Management system,by adopting PWM/0-10V dimming technology, it mainly realizes the switch  On/Off of lamps and dimming 0%~100%.

It adopts the latest LORA Communication Technology and Self-Organizing Network Communication Technology, which has advantages of Free Wiring, Low Power Consumption, Long Transmission Distance and other advantages to work with our Two-Way Communication CC(Centralized Controller) which is independently developed by our company, which can remote On/Off, 0%~100% Dimming, Electric Energy/Data acquisition, Fault Detect,etc.

II. FUNCTIONS

     1.  Control Function     

  1.1: SCL(Smart Lighting Controller) will control the Power Supply Circuit On&Off and the Illumination Changing of the lamp through  LoRa Wireless Communication Channel under the management of the Intelligent CC(Centralized Controller) and other Management Devices, with range of 0%~100%.

  1.2: Automatically control the Power Supply Circuit On&Off and the Illumination Changing of the lamp according to the Schedule(Timetable), with range of 0% to 100%.

     2. Communication Functio

      2.1. Uplink LoRa Communication, Communication Distance between LoRa Single Lighting Controller and Intelligent Lighting Centralized Controller is 500m to 800m, Mesh Networkin

3. Fault Alarm Function

The Single Lamp Smart Controller(SLC) can Automatically report the Fault Information to the Centralized Controller(CC) and other Management Equipment;the Intelligent Lighting CC and other Management Equipment will continuously inquire the status of the Smart Single Lighting Controller.

     4. Illuminance Sensing Function

The Smart SLC can calculate the average illuminance of the surrounding environment, can be intelligently switching On&Off the Lamps when disconnected from the Managements System.  

     5. Power Acquisition Function

Electric Energy Parameter Collection, can record the lamp’s  Electricity Consumption.

      6. The Enclosure

 Follow the International Standard NEMA Interface Housing, Compact and Easy to Install.

IV:  Wiring Diagram

V: Attention

1. It is forbidden to connect one SLC to Multiple Drivers, and the Max. power of Driver does not exceed 400W (220V) or 200W (110V).Since Multiple Drivers are connected in Parallel, the internal Capacitance is equivalent to a Large Capacitance, and the reverse Discharge of the Capacitor at the moment of Switching On/Off will affect the life of the Relay Switch.

2. The SLC should be connected correctly and firmly to avoid short-circuit and fire caused by wrong wiring or improper wiring.

3. Due to the differences in the Dimming Curve Parameters of LED Drivers among various power supply manufacturers, our company only guarantees that the Dimming Output signal of the controller is Linear, and does not guarantee that the illumination changes to linear when work with power supply. If the lamp illumination is required to be changed to linear, our company can provide Freely Testing Service and Calibration of Dimming Curve, customers are required to provide lamps and Testing environment.
