Brief Analysis on the Advantages of Using Industrial Ethernet Technology on Highways

As industrial equipment becomes increasingly intelligent, Industrial Ethernet has emerged from the field of industrial communications with its networking functions and open features, becoming the mainstream trend in the industry. Many manufacturers have also increased their investment in an effort to seize the opportunity of Industrial Ethernet.

Industrial Ethernet uses switched Ethernet technology to provide an interactive mechanism for the coordination and cooperation between controllers, operation stations, and various workstations, and seamlessly integrates with the upper information network. Currently, industrial Ethernet has gradually taken a mainstream position in the monitoring layer network and is penetrating into the field device layer network. Industrial Ethernet has many advantages over previous automation technologies.

Punan Expressway is the second expressway in northern Fujian, with a total mileage of 245 kilometers and a total investment of RMB 9.8 billion. Construction started in December 2005 with a contract period of 3 years. There are 99 large and medium-sized bridges and 24 tunnels along the entire line, which basically adopts a two-way four-lane design, and a six-lane design is adopted for some sections in Wuyishan. After the completion of Punan Expressway, it will only take more than four hours to drive from Pucheng to Fuzhou.

The starting point of the Pu'nan Expressway is located in Guanlu Township, Pucheng County, at the junction of Fujian and Zhejiang. It connects to the Huangqu Expressway in Zhejiang Province, and connects to the Nanping section of the Beijing-Fuzhou Expressway, which has been opened to traffic, in Yanping District, Nanping, connecting Wuyishan, Jianyang, and Jianou. Its construction further improves the traffic conditions in northern Fujian, optimizes the investment environment, drives the development and opening up of areas along the line, and further improves the transportation network of Fujian Province from east to west, making Nanping a better connection point for the interactive development of the West Coast Economic Zone of the Straits and the Yangtze River Delta, and an extension area radiating inland.

The entire highway has 18 tunnels and 231 monitoring transmission points. Each tunnel is mainly responsible for six parts: PLC lighting, PLC wind control, PLC lane indication, fire alarm, vehicle inspection device, and information board. A dual-fiber ring network is used from the tunnel to the tunnel entrance machine room, FDU equipment is used from the tunnel entrance machine room to the sub-center, and fiber optic transceivers are used from the tunnel entrance machine room to the toll station. FDU equipment or fiber optic transceivers are used from the toll station to the sub-center and service area. The trunk network is completed by 9 FDU devices. The above is the use of Omate 6000 equipment from the tunnel to the tunnel entrance machine room to transmit the Ethernet data collected in the tunnel to the fiber optic transceiver or FDU equipment. Among them, Zhuyuan Tunnel uses 50 Omate 6000 devices to form a ring network, which focuses on the redundancy of industrial Ethernet equipment.

Solution Advantages

1. Industrial quality, low power consumption, fanless design, solid and flexible structure, wide temperature and humidity range. It should be able to work in harsh environmental conditions, such as high temperature, humidity, strong electromagnetic interference environment.

2. The network is simple, reliable and scalable. The system has simple and flexible expansion and intelligent upgrade functions, which facilitates the continuous expansion of the system.

3. Networking: On-site information distributed in various locations can be managed and viewed synchronously and in real time through a proprietary communication network.

4. The information resources of each management station can be fully shared with other management systems and coordinated in a unified manner as needed.

5. Omate 6000's excellent switching performance and extremely fast 30ms self-healing capability greatly ensure reliable and timely transmission of tunnel data. When a fiber break occurs, the ring network can automatically resume normal operation within 30ms.

6. High real-time performance and supports fault self-diagnosis function.

7. Support dual power supply redundancy to improve equipment reliability.

8. Omate6000 can divide VLANs according to different services to isolate service data without affecting each other.

9. Omate6000 has the SNMP standard network management function, which can easily manage the network.
