Project background:

In general, the highway tunnel is unattended, and the distance between the tunnel and the monitoring center is far. It is necessary to build a highly reliable network platform which can adapt to the tunnel environment to ensure the real-time uploading of various monitoring data in the tunnel and the real-time monitoring of tunnel equipment by the monitoring center, so as to realize the normal operation of the tunnel. The harsh environment of tunnel monitoring system and the requirement of real-time data make industrial Ethernet switch the best network scheme of tunnel monitoring system at present.

Requirements for Industrial Ethernet Switches in highway tunnel monitoring system:

♦ Industrial quality, adapt to harsh environmental requirements

♦ Flexible networking, high reliability, and high scalability

♦ Network redundancy is supported to ensure real-time and reliable data

♦ Power Supply redundancy, high reliability

♦ VLAN Support

♦ Supports network management for remote device management
