Application of Industrial Switch in Intelligent Transportation

With the rapid development of China's economy, the number of urban traffic roads is increasing, the number of motor vehicles and road traffic flow are increasing significantly, and the resulting traffic congestion, motor vehicle violations and other phenomena are becoming 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 the urban traffic conditions, a single artificial management relying on traffic police can no longer meet the needs of modern traffic management. On this premise, it is imperative to improve the modernization level of expressway and urban traffic management, and high-tech means are urgently needed to enrich and strengthen the level of traffic management.

The intelligent transportation system is an integrated application of information technology, data communication transmission technology, electronic sensor technology, computer technology and control technology to the ground traffic management system, referred to as ITS. Intelligent transportation can effectively use existing traffic facilities, improve traffic efficiency, reduce traffic load and environmental pollution caused by traffic, and ensure traffic safety. By using the intelligent traffic management system, managers can control the traffic flow to the best state to ensure the maximum social and economic benefits.

The intelligent transportation system requires massive data to be exchanged and transmitted, such as video image data of surveillance cameras, control signal data of various traffic facilities, and audio data of traffic monitoring and command. These data need to be transmitted to the monitoring center through data transmission lines for unified management, and the monitoring center also needs to transmit relevant data to each monitoring site node for unified command. Massive data exchange requires a real-time data transmission system capable of carrying high data flow. Ordinary TCP/IP network cannot meet the demand of high data flow, and industrial Ethernet must be used to meet the demand.

Advantages of Our Industrial Switches in Intelligent Transportation

In order to create a reliable multi service intelligent traffic command platform, the support of the network platform must be highly reliable and adapt to the requirements of multi service and multi platform access: 1. The network equipment must be stable and reliable to meet the needs of multi concurrent and multi service; 2. It has good scalability to meet the needs of later expansion; 3. It has management functions to achieve unified management of multi service equipment. At the same time, the intelligent transportation industrial switch is required to have the following characteristics:

Components: the selection of components is required to be higher and better adapt to the needs of industrial production sites

Mechanical environment: It can better adapt to harsh mechanical environment, including vibration resistance, impact resistance, corrosion resistance, dust prevention, waterproof, etc.

Climate environment: It can better adapt to poor climate environment, including temperature, humidity, etc.

Electromagnetic environment: It has strong electromagnetic interference resistance

Working voltage: the working voltage range is wide

Power supply design: the power supply is generally dual power redundancy design

Installation method: DIN rail, rack and other installation methods can be used

Heat dissipation mode: fanless enclosure is generally used for heat dissipation

Based on the above requirements, we have customized a set of intelligent transportation industrial switch solutions, with the following advantages:

Multi service interface, supporting multiple service slots+management slots

Support equipment cascading, with super scalability and multi service access requirements

Support dual power supply, switching power supply overvoltage and overcurrent protection, power output ripple and noise less than 50MV

All aluminum alloy shell, good shielding and strong anti-interference

Visual management, supporting unified management of remote supporting products

The field equipment at the road mouth is capable of working in a wide temperature environment of - 40~85 ℃, and can adapt to various bad traffic scenarios

Industrial ring network design, the ring network self-healing time is ≤ 20ms, when communication failure occurs, data will be transmitted along the redundant link, improving the network redundancy and reliability

The stepped bandwidth design eliminates data congestion caused by data bursts;

The design of optical fiber ring network not only ensures the fast and real-time transmission of data services, but also ensures the reliability of communication transmission.

Based on the above solutions, our Intelligent Transportation Industrial switch provides a strong guarantee for users to build a stable and reliable video private network and effectively simplifies user operation and maintenance while meeting users' demand for high-quality basic network products.

We are committed to creating an interconnected network for users and endowing the network itself with the ability of security, so as to inject security energy into the basic network products. At present, our industrial switch products have been widely used in traffic automation, industrial automation and power automation. In the application of railway, light rail, subway, expressway, airport, wharf, metallurgy, paper making, automobile, wind power generation, water conservancy and hydropower, water supply and water treatment, petrochemical, pipeline and regional backbone network and other industrial key tasks and harsh environments, it is applicable to the requirements of strong electromagnetic interference, high ambient temperature, high mechanical load and rail clamping installation. In the future, we will make better use of industrial switches to support the overall network construction of intelligent transportation and help the development of intelligent transportation!
