Ⅰ. The Background Analysis
With the rapid development of China's economy, urban traffic roads continue to increase, the number of motor vehicles and road traffic volume have increased substantially, and the resulting violations of motor vehicles have become increasingly serious, posing a great threat to the personal safety of the people and affecting the normal urban traffic order. In order to create a good urban traffic environment and improve urban traffic conditions, the single man-made management relying on traffic police can no longer meet the needs of modern traffic management. Under this premise, the improvement of the modernization level of highways and urban traffic management is imperative, and it is urgent to adopt high-tech means to enrich and strengthen the level of traffic management.
Ⅱ. Demand Analysis
· The system
integrates red light vehicle detection, picture capture and transmission.
· It can provide law
enforcement basis for the city public security traffic management department to
effectively prevent traffic violations
· It can automatically
store and process the captured data and dock the administrative system.
· The equipment should
meet the extreme outdoor working environment and adapt to extreme high
temperature, low temperature, humidity and other application scenarios. ·
· Provide 7*24 hours
of stable reliability.
Ⅲ、The Solution (Network Topology)
Ⅳ、 The Program Features
· -40-75° stability at extreme temperatures The roadside field equipment has a wide temperature environment working capacity of -40 to 85 °C, and can adapt to various bad traffic scenarios.
· 10ms ring network self-healing, ensuring high-speed line stability Industrial ring network design, ring network self-healing time ≤ 10ms, when communication failure occurs, data will be transmitted along redundant links, improving network redundancy and reliability.
· Dual power supply redundancy design The equipment involved in the scheme is designed with redundant dual power input. When one power supply is powered off due to human or natural factors, the other power supply continues to work normallyand does not affect the communication system to transmit data.
· The uplink is optical port, the transmission is fartherand the forwarding delay is smaller. Adopting the optical port uplink design, the fiber ring network is one of the best topology designs with the smallest transmission delay and the highest redundancy and reliability. It not only ensures the fast real-time transmission of data services, but also ensures the reliability of communication transmission.
· Intelligent AI function to automatically recover the bad working condition of the device Fengrunda AI industrial PoE switch supports AI PoE function. When the device is suspended or disconnected, the switch can automatically detect the problem and restart the device to resume normal operation.
