Smart Industrial Park Road System Solution

Integrated Application of Solar Street Lights and Renewable-Energy Smart Poles

1. Project Background and Needs Analysis

Modern industrial parks typically cover large areas, feature dense road networks, and experience frequent movement of vehicles and personnel around the clock. Traditional industrial-road infrastructure commonly faces the following challenges:

• High lighting energy consumption and inefficient management
• Inadequate illumination in some areas alongside excessive lighting in others
• Scattered security-monitoring points and blind spots along the perimeter and internal roads
• Limited capabilities for vehicle dispatching, personnel positioning, and environmental monitoring
• Uneven communications coverage throughout the industrial park
• Slow response to emergency incidents

At the same time, factories are highly sensitive to energy costs. How to reduce infrastructure energy consumption while ensuring production safety has become a key concern for industrial-park operators.

The combination of solar street lights and renewable-energy smart poles provides an effective pathway for upgrading industrial-road infrastructure. Solar street lights use clean energy for independent power supply, eliminating the need for cable installation and reducing electricity costs. Renewable-energy smart poles integrate video surveillance, environmental sensing, wireless communications, information displays, emergency alarms, vehicle charging, and other functions into the lighting infrastructure.

This enables “multiple functions on one pole and unified management through one network.”

Based on years of experience in smart poles and renewable-energy applications, Sanqian Smart has developed an integrated solution combining solar street lights and renewable-energy smart poles for industrial environments. The solution helps factories create a safe, green, efficient, and intelligent road environment throughout the industrial park.

5. Smart Management Platform Functions

The Sanqian Smart Industrial Smart Road Management Platform serves as the central management system for the entire solution.

Lighting Strategy and Energy Management

Based on factory shift schedules, sunrise and sunset times, and vehicle and pedestrian density, the platform automatically executes time-based lighting strategies.

For example:

• Full-power lighting during shift-change periods
• Lighting reduced to 30% during low-traffic nighttime periods
• Sensor-based activation when vehicles or personnel are detected

The platform records the power generation, electricity consumption, and energy-saving rate of each light and generates energy reports to support the factory’s carbon-accounting activities.

Video and Security Coordination

Smart-pole cameras transmit live video to the platform.

The system supports:

• Electronic-map positioning
• Video patrols
• Perimeter-intrusion alerts
• Coordinated security responses

When an emergency alarm is triggered, the platform automatically retrieves footage from multiple nearby cameras, allowing security personnel to assess the situation and issue remote voice announcements.

Environmental and Safety Monitoring

The platform displays environmental heat maps for the industrial park in real time.

Automatic alerts are generated when noise levels or hazardous-gas concentrations exceed configured thresholds, supporting the factory’s EHS management.

Full-Life-Cycle Device Management

Each light and smart pole is assigned a unique identification code.

The platform records:

• Operating status
• Fault history
• Maintenance records
• Service history
• Asset information

This creates a digital asset register for the entire lighting and smart-pole system.

Maintenance Work Orders

When a fault is detected, the platform automatically generates a work order and sends it to maintenance personnel through the mobile application.

The system supports:

• QR-code repair requests
• Photo uploads
• Work-order tracking
• Closed-loop completion

This helps maintain a high equipment availability rate.

6. Example of Power Distribution and Energy-Storage Design

The following example is based on the primary road of an automotive-parts factory.

• Road width: 12 meters
• LED power per light: 100 W
• Daily operating time: 11 hours
• Full-power operation: 5 hours
• 50% power operation: 6 hours

The daily energy consumption of each light is calculated as follows:

5 h × 100 W + 6 h × 50 W = 800 Wh

A 12.8 V/80 Ah lithium iron phosphate battery provides approximately 1024 Wh of stored energy, which can support normal lighting for four consecutive cloudy or rainy days.

A 200 W photovoltaic module is selected. Based on an average of four effective peak-sunlight hours per day, the estimated daily power generation is approximately 800 Wh.

Combined with an MPPT controller efficiency of more than 95%, the system can achieve a balanced energy supply.

In regions with insufficient solar resources or frequent rainfall, the photovoltaic capacity can be increased to approximately 250 W to ensure reliable operation during winter.
