China has many populous cities with busy highways and often congested traffic. Traffic flows are often jammed at certain road bends or sections due to things like bad weather and congestion which can cause accidents. Accordingly, a highway tunnel monitoring system was needed to help reduce traffic jams resulting from incidents or vehicle breakdowns. In this blog, ESIS takes a detailed look into one tunnel monitoring system and how it effectively offered a solution using fanless PCs.
This application is a highway tunnel monitoring control system for a Chinese southwestern province, which incorporates a number of subsystems including lighting, ventilation, traffic guidance, CCTV, fire alarm, fire suppression, and emergency telephone system and broadcasting system.
For this project, an Advantech fanless embedded controller ITA-1611 was used for front-end processing for the fire alarm and fire suppression system. Running on a low power Atom processor with onboard memory, wide-temperature and wide-voltage support, Advantech ITA-1611 can operate stably and reliably 24/7 in machine rooms inside of highway tunnels. Supporting up to 6 x RS-232/422/485 serial ports, ITA-1611 can connect with various sensors or transducers in the disaster prevention system.
Advantech provided a comprehensive tunnel monitoring and control system for the entire highway network in Yunnan Province. Now, it is possible to adjust traffic flows, control ventilation, and pre-emptively avert traffic incidents from the central control station, providing safer, more comfortable, and faster journeys to all road users.
