Industrial ITS Transmission Solutions

Roadside Communication Equipment | ITS Network Solutions Provider

Smart cities utilize information and communication technologies to sense, analyze and integrate key information from the core systems of city operations, so as to respond intelligently to the different needs of people’s livelihoods, environmental protection, public safety, city services and industrial and commercial activities. Its essence is to realize intelligent city management and operation through advanced information technology, thereby creating a better life for citizens and promoting balanced and sustainable urban development.

The Pain Points Analysis of Intelligent Transportation Communication.

1.The scale of the communication network is large, it the difficulty to integrate communication systems and the lack of professional communication solutions.
2.Access layer communication products are widely distributed, multi-point communication and outdoor environment are very different, and access network stability requirements are higher.
3.Many subsystems, flexible and variable networking, complex types of access equipment, and difficult and challenging late operation and maintenance.
4.Redundant communication needs, there is a demand for all kinds of ring network networking applications. The system requires strong fault tolerance, fast self- healing speed, and smoother transmission, and the traditional communication solutions need to be optimized and upgraded.

Communication System Network Solutions

The traffic communication system can be divided into core, convergence, and access. The network hierarchy can clearly define the interface and function of each network layer, realize good planning of the network, and make full use of equipment and link resources.

Core layer: Located at the uppermost layer of the network, it is the data exchange hub of the communication system. Completing the data exchange between the front-end devices of each subsystem and the servers of each system platform in the center and realizing the functions such as docking with the public security network and other private networks.
Convergence layer: Located in the middle layer of the network, it is the main body of the communication system and is responsible for the convergence and transmission of data of each subsystem. It provides high-speed, low-latency, and high-reliability transmission channels for services.
Access layer: located in the lower layer of the network to achieve the end of the communication system access. As the front-end equipment interface form of intelligent transportation systems, transmission needs vary, the installation environment is complex, corresponding to different markets, and the network access is also flexible and diverse ways to achieve.

The Core Layer Network Solution

The intelligent transportation system in the command center installs the core switch to achieve a layer3 core exchange of data. The command center network is formed by the core switch and the command center server, the center access switch, etc.

The platform layer of the intelligent transportation system is built by the intelligent transportation operation and maintenance platform, the video integrated management platform, picture storage system, NAS storage system, extensive screen display system, central control subsystem, and other equipment. The primary devices are various application servers (database server, platform application server, operation, maintenance management system server, streaming media storage and forwarding server, monitoring center management server, etc.) and storage devices.

Each application server is assigned two IP addresses of different network segments by dual NICs connected to the central access switch in the main server room. VLAN division is performed at the central access switch to divide the dual NICs into different virtual LANs. The servers in the command hall adopt the same access mode to ensure reliable transmission of traffic management data through network redundancy. The dual uplinks of the central access switch connect to the primary and backup core switches, respectively. The main and backup redundant links ensure reliable data transmission.
