Location: Near Huawei Headquarters, Dongguan, China
Project Overview
This PLC (Power Line Communication) smart street lighting project was successfully completed near the Huawei headquarters in Dongguan, China. The project demonstrates how a simple PLC-based lighting control system can deliver reliable remote management and significant energy savings without complex installation or additional communication wiring.
By leveraging existing power lines for data transmission, the solution provides an efficient and cost-effective upgrade from traditional street lighting to an intelligent lighting system.
Solution Architecture
The project adopted a PLC-based street lighting control solution, consisting of:
- PLC Concentrator
Installed in the control cabinet, the PLC concentrator serves as the central communication and management unit. It collects data from street lights and sends control commands through existing power lines. - PLC Dimmable Driver (PLC Dimmer Driver)
Integrated into each street light luminaire, the PLC dimmer driver enables on/off control, brightness adjustment, and status feedback via power line communication.
Using the existing electrical infrastructure, the system forms a stable PLC network without the need for additional signal cables or wireless gateways.
Key Features & Advantages
1. Simple Installation
No new communication wiring is required. Devices are deployed directly on existing power lines, significantly reducing installation time and labor cost.
2. Smart Remote Control
Operators can remotely switch lights on/off and adjust brightness levels through the PLC concentrator, improving operational efficiency.
3. Energy Saving Through Dimming
By implementing scheduled or demand-based dimming, the system effectively reduces power consumption while maintaining adequate lighting levels.
4. Stable and Secure Communication
PLC technology ensures reliable data transmission, unaffected by common wireless interference, making it suitable for urban and industrial environments.
5. Low Maintenance Cost
Real-time status monitoring helps detect faults quickly, reducing on-site inspection and maintenance efforts.
Project Results
- ✔ Rapid deployment with minimal on-site construction
- ✔ Stable PLC communication across the street lighting network
- ✔ Achieved customer requirements for smart control and energy efficiency
