Time:2025-06-19 Views:356
I. Overview
Running a red light is one of the significant violations in urban traffic, causing chaos in traffic order, congestion, and traffic accidents. The urban traffic guidance system is a crucial means to improve the efficiency of urban road traffic, effectively guiding the movement of vehicles, reducing travel time, and ultimately achieving a balanced distribution of traffic volume across the entire road network.
II. System Requirements
1. Real-time publication of guidance information with a highly reliable network,
2. Real-time and rapid forwarding of guidance system data, requiring low latency in network transmission
3. Various bus interface transmission capabilities, such as RS 232/485/422, etc.
4. Adaptation to various harsh temperature environments at intersections
5. Use of industrial-grade standard switches.
III. Solution
Solution Introduction:
This solution has a clear hierarchical structure, with the intersection control box serving as the network access layer. It utilizes Wintop's industrial Ethernet switch RS205-1F4T with 1 optical and 4 electrical ports, as well as RS202-1F1T (1 optical, 1 electrical transceiver) and RS203-1F2T (1 optical, 2 electrical transceiver), responsible for accessing data from high-definition cameras and signal controllers at the intersection. The switch inside the control box uplinks to the monitoring center via single-mode fiber.
This solution not only effectively resolves network congestion but also ensures the entire network operates efficiently and at high speed, resulting in smoother video and signal collection without delays. All of Wintop's industrial Ethernet switches pass EMC Level 4 testing, effectively avoiding impacts on the entire system caused by electromagnetic interference, achieving stable and effective operation.
IV. Product Advantages
1. Ultra-high industrial hardware design, power protection, port protection
2. Highly reliable dual power redundancy protection
3. Extremely large backplane bandwidth and large cache technology for fast and efficient data forwarding
4. IP40 protection level, MTBF ≥ 10 years, and unattended operation
5. Real-time publication of guidance information with a highly reliable network,
6. EMC Level 4 design with high resistance to lightning surge.
