Rugged Wide-Temperature AM5728 Makes High-Speed Rail Pantograph Video Monitoring More Reliable

China's railway development is rapid, with the total length of railways expected to reach 120,000 kilometers by 2020, of which 18,000 kilometers will be high-speed railways operating at over 200 km/h. In recent years, with the increasing number of IT intelligent devices and applications, the construction of China's high-speed railways has reached its peak. Among them, video surveillance systems have played a prominent role in improving communication for China's high-speed railways.

Application Requirements

Modern high-speed trains are electrically powered via a pantograph, which is mounted on the train's roof and collects current through sliding contact with overhead power lines. Therefore, the condition of the pantograph is difficult to monitor and is susceptible to environmental factors or obstructions during operation. If unexpected events occur, such as a garbage bag entanglement or a broken overhead line, the pantograph's power grid transmission system will experience a short circuit or malfunction. Therefore, real-time video monitoring of the pantograph can proactively and effectively detect problems, allowing sufficient time for repair and maintenance.

Solution

To meet the requirements of high-speed rail video monitoring, we procured and evaluated Xinmai's high-performance, low-power AM5728 system-on-module (SOM) and evaluation board. This single-board computer is rugged and highly reliable, supporting wide-temperature operation from -40 to 85°C, ensuring long-term stable operation in harsh environments.
