Smart Transportation Solution - Harbin Tieke Expressway Smart Upgrade

In the frigid heart of Harbin, Heilongjiang Province, a major transportation artery running from Fangzheng County to the border of Yanshou and Shangzhi is undergoing a quiet transformation. The Tieke Expressway Fangzheng-Yanshou-Shangzhi section project, a 76.9-kilometer-long icy and snowy route, faces multiple challenges, including extreme low temperatures, complex terrain, and high reliability. ONV, with its industrial-grade, full-scenario networking solution, is building a solid digital foundation for this vital transportation artery.

• Uninterrupted service: Billing, monitoring, and communication systems require stable operation 24/7.
• Power supply fluctuations: High risk of lightning strikes in outdoor environments, voltage fluctuations ±20%.
• Extreme low temperature testing: Winter extreme temperatures reach -40℃, causing frequent freezing of ordinary network equipment.
• Extremely difficult maintenance: Heavy snowfalls pose significant challenges for maintenance personnel, making troubleshooting difficult.

• Operating from -40℃ to +75℃, 6KV lightning protection, and IP40 protection rating.
• ERPS ring network protection technology (<20ms), instantaneous fault switching ensures zero service interruption.
• 8*1000M RJ45 ports and 4*1/10G Optical ports with flexible configuration, supporting full line-speed forwarding.
• Dual redundant power supply design, supporting DC12~57V input, with a self-developed power supply supporting AC90~264V input.

• Physical layer reinforcement: Aluminum alloy reinforced chassis, shock and corrosion resistant, fanless, silent design.
• Protocol layer redundancy: Dual-protocol support of STP/RSTP/MSTP (<50ms) + ERPS (<20ms)
• Service layer intelligence: IPv4/IPv6 dual-stack support, ACL security policies, QoS service assurance

Unified network management software platform, enabling visualized management of the status of all network devices.

• Platform: Visualized management of the entire network device topology, automatic diagnosis of anomalies and alarms
• Mobile: Real-time push notifications of device alarms, zero-latency triggering of maintenance responses

• Full network device visualization: Automatic topology discovery, real-time status monitoring
• Fault early warning and location: Millisecond-level awareness of the health status of all access points
• Remote centralized management: Support multiple management methods, including Web, CLI, and SNMP

• Continuous and stable operation in extremely low-temperature environments down to -40℃, with zero packet loss at ports, fully meeting the requirements of frigid conditions.
• Power Supply: Supports AC90~264V input, adapting to voltage fluctuations in outdoor environments, reducing the power supply failure rate by 90%
• Remote Management: Reduces the frequency of on-site maintenance; real-time alarm location achieves zero latency. Troubleshooting revealed that no on-site manual intervention is needed during blizzards, resulting in annual maintenance cost savings of 60%.

• System Availability 99.99%: Zero interruption of core business operations since commissioning
• Fault Response Time <1 minute: Remote diagnostics automatically locate faults
• Long Equipment Lifespan: Industrial-grade design ensures a 10-year lifespan
• 40% Energy Consumption Reduction: Fanless design + intelligent power management

"In the extreme cold of -40 degrees Celsius, the ONV industrial switch acts like a 'neural network' for a highway, operating stably 24/7 and providing us with reliable data transmission. Especially during blizzards, the equipment's stable performance exceeded our expectations." — Project Manager of Tieke Expressway.
