In mountainous areas, tunnels are frequently used for highways and railways, and ensuring safety is of utmost importance. Tunnels require various systems such as fire protection, ventilation, traffic guidance, communications, and lighting. Additionally, it is essential to send real-time tunnel monitoring data or messages to networking personnel in a remote control center so that immediate actions can be taken in case of system failures or accidents.
CTC Union offers a comprehensive "Tunnel Control" solution that incorporates different devices to create layered tunnel control systems. These devices aim to provide reliable services and minimize the risk of potential accidents, particularly fires. For example, the use of bypass switches in a ring topology allows for redundant connections even in the event of a power failure in a node. Furthermore, an integrated EMS system automatically collects real-time data or messages from devices placed in the tunnel, enabling networking personnel to supervise and monitor tunnel traffic safety from the remote control center.
By adopting CTC Union's complete "Tunnel Control" solutions, connections remain always-on during data transmission, and the use of optical connections enhances transmission security over longer distances. Moreover, future maintenance or upgrades become more convenient and easier with point-and-click Web configuration pages.
There are several challenges associated with tunnel control systems. The devices deployed in tunnels must withstand harsh operating environments. Reliability and uninterrupted service delivery are essential in tunnel scenarios. Additionally, personnel responsible for tunnel safety in the remote control center need to take immediate action in the event of accidents.
CTC Union addresses these challenges by offering a range of networking devices designed to meet rigorous safety standards. These solutions enhance safety measures and integrate operational information into a centralized management system for future analysis and planning.
One example of the application of CTC Union's tunnel control system involves IBP-202 Bypass switches connecting to PLC controllers that manage the tunnel ventilation system. Multiple IBP-202 Bypass switches within the same tunnel are interconnected in a ring topology to ensure redundancy. For long-distance data transmission back to the remote control center,IMC-100C is responsible for transmitting data via fiber optic cables.
In the remote control center, the SmartView EMS helps monitoring personnel collect data or messages from devices in the tunnel. By analyzing this information, the personnel can adjust device settings based on real needs, avoiding energy waste during periods of low activity.
