Domestic rail transit (including subway, light rail, passenger dedicated line and high-speed rail line) has developed rapidly and become a national business card industry and promoted to overseas markets. Rail transit has high sensitivity to safety production and a large amount of maintenance work. There are many potential insecurities when crossing densely populated areas and complex geological conditions. At present, there are still many work to be carried out to strengthen traffic safety control and protect the country. , the personal and property safety of enterprises and people.

Otto developed the high-speed railway intelligent prevention and control system based on the wireless ad hoc network for the University of Communications and Electronic Science and Technology, and carried out the experimental construction in the Hepu-Beihai section of the North Railway Line of the Guangxi Railway, which is currently on the high-speed rail line of the Guangxi Railway. It is currently undergoing acceptance and succession. In the research stage of capacity and business promotion, we strive to build a comprehensive capability support system covering comprehensive protection along the line and station, train over-the-horizon safety warning assisted driving, maintenance operation information, vehicle broadband communication and in-vehicle wireless communication service.

The system has a variety of business support capabilities:

It provides railway public security with the ability to intrusion early warning and abnormal automatic warning along the railway. It can improve the video identification and matching ability through AI system, reduce the probability of false alarms such as wind and grass, and make the automatic alarm capability authentic and credible;

Facing the railway operation and maintenance department, designing an information operation platform based on the wireless broadband access capability of the full-line operation surface, greatly improving job scheduling and management efficiency, and providing convenient means for remote diagnosis and operation assistance;

Multi-source multi-dimensional sensors along the line, through sensor network and multi-level multi-level distributed computing, information elements extraction real-time, low network transmission delay, through the special over-the-horizon safety driving assistance system to provide timely warning to train drivers, Effective disposal capacity;

The good scalability of the self-organizing network provides wireless communication access capability for emergency rescue teams and equipment.
