Project Introduction

As Yeaplink’s technical support lead, I witnessed our Vehicle Gateway transform Stockholm’s street cleaning operations. Our SV900 gateway powers their autonomous cleaning fleet.

Initial Challenge and Requirements

Stockholm Municipality faced significant challenges with traditional street cleaning methods. Therefore, they approached us with specific requirements:

• 24/7 operation capability in harsh Nordic weather
• Real-time fleet management for 30 autonomous sweepers
• Secure data transmission for operational commands
• Reliable positioning system for precise navigation
• Remote monitoring capabilities
• Integration with existing city management systems

Technical Implementation Details

Hardware Setup

We selected the SV900-00 model with dual 5G modules. Each autonomous sweeper received:

• 8 Fakra connector antennas for optimal 5G coverage
• 4 WiFi antennas for local communication
• M12 aviation connectors ensuring stable connections
• Dual SIM configuration for network redundancy

Power Management

The SV900’s wide power input range (DC 9~48V) perfectly matched the sweepers’ electrical systems. Therefore, we implemented:

• Direct connection to the vehicle’s 24V power system
• Power consumption optimization settings
• Automatic power state management
• Overcurrent and overvoltage protection systems

Network Architecture

We established a comprehensive networking structure:

• Primary 5G connection through Telia network
• Secondary 5G connection through Telenor network
• VPN tunneling for secure data transmission
• MQTT protocol for real-time data exchange
• Bandwidth management for video streaming

Environmental Adaptations

Stockholm’s climate demanded specific configurations:

• Temperature monitoring systems activation
• Heater control integration
• Moisture prevention protocols
• IP40 protection enhancement measures

Operational Implementation

Control Center Setup

We established a central monitoring facility featuring:

• 24/7 operational capability
• Real-time fleet visualization
• Advanced routing algorithms
• Predictive maintenance systems
• Emergency response protocols

Data Management

The system processes various data streams:

• Real-time location data (GPS/BeiDou)
• Operation status metrics
• Environmental sensors data
• Battery management information
