From Bus to Ethernet, Signal Light Control is a Cornerstone of Road Transportation
Industrial grade switches have come to play a key role in signaling systems, especially in outdoor traffic control environments. As signal hosts need to handle a large amount of real-time traffic data, especially with the development of intelligent signal systems, video analysis and become extremely important research and judgment data, the traditional bus has been unable to guarantee the real-time data and large bandwidth, and industrial grade switches provide a highly reliable and low-latency network connection, to ensure that the traffic signal control data is delivered in a timely manner.
Application Scenario:
1、road traffic signal control box industrial grade switch is installed in the control box of the road intersection, through the fiber optic connection, the traffic data from different directions will be converged to the central control system, and can even be used as the convergence point of the video and radar data of the surrounding intersections.
2、remote monitoring and management: industrial grade switches support a variety of protocols and interfaces, and can be seamlessly integrated with a variety of sensors, traffic signal controllers and other equipment. They can transmit the collected traffic data to the traffic management center via TCP/IP network to realize centralized management and remote control, and can differentiate the service channels according to multiple converged services without interfering with each other.
3、networking flexibility and redundancy and reliability: redundancy design of industrial-grade switches (such as support for ERPS redundant ring network) further improves the reliability of the SCATS system, even in the case of a single-point network failure, the data can be switched to the reverse transmission to maintain unobstructed, to ensure that real-time adjustments to and optimization of traffic signals.
Advantage:
– High anti-interference: industrial grade switches have excellent anti-electromagnetic interference capability and adapt to various complex electromagnetic environments.
– Strong stability: industrial-grade switches can still operate stably in extreme temperature and humid environment to ensure the continuity of traffic signals.
