Tunnel Monitoring

In order to balance the development between city and township and make more convenience transportation in between, one of the important engineering projects is to develop the tunnel system. Therefore, to build up the reliable and stable tunnel monitoring system has become an important project for all the governments in the world. Nowadays the intelligent highway traffic system was implemented by the latest control and information technology, along with 3C technology, open network communication system and PLC’s outstanding reliability, interference immunity and flexibility of control that becomes the kernel of the tunnel monitoring system.

The communication network in the tunnel monitoring system is the crucial to ensure the system can operate efficiently. The network nodes and regional network control stations are increases significantly along with more and more long tunnel, extra-long tunnel and the advent of tunnel groups has been constructed. The communication network should not only have the high speed communication to ensure the effective transfer of information, also need to features with the fault-tolerance capabilities to improve the reliability of communication. The self-recovery features should be achieved immediately while the network fails, and the hardware design should meet the industrial requirements to adapt the harsh working conditions in the tunnel.

There are many subsystem inside the tunnel monitoring system, including lighting systems, ventilation systems, passenger guiding systems, fire alarm systems, fire control systems, emergency telephone system and radio system. All signals between these subsystems were used as the management database that must be sent to the tunnel monitoring center through the network equipment. All the Netzin Industrial Managed Ethernet Switches were pass the standard industrial environment test during production which to guarantee its extremely high stability operation and effective transmission of the data information inside the harsh tunnel environment. In addition, the feature of software ring make system architecture has greater scalability and ductility, to make the tunnel monitoring application more flexible and expandable to meet future demand. Netzin Ethernet Switch is your excellent choice of network equipment in tunnel monitoring applications.
