The voltage of the power supply line of a certain base station near Gujiao City has fluctuated. "On the large screen of the Taiyuan Communication Section Network Adjustment Area of China Railway Taiyuan Bureau, a light spot suddenly flickered from green to red. Song Yang, the foreman of Taiyuan North Transmission Work Area, stared closely at the screen and quickly issued instructions: "Retrieve related data and notify relevant work areas to pay more attention!" The flashing light on the screen reflects the operating status of communication towers along the Taiyuan Railway. Communication towers are important carriers of signal transmission, which are related to transportation safety. In recent years, the number of towers maintained along the Taiyuan communication section has exceeded 8398. In order to cope with challenges such as storms, geological activities, and equipment aging, the research and development team of Taiyuan Communication Section has developed the "Railway Trackside Tower Tilt Online Monitoring System". This system integrates data collection, precise monitoring, and intelligent diagnosis, just like putting a 'health bracelet' on every tower. With the help of high-precision inclinometers and other sensors, we can conduct 24-hour online monitoring and trend analysis. ”Song Yang pointed to the constantly refreshing real-time parameters on the screen and said. In the past, the inspection of communication towers relied on regular manual hiking, walking through sections and tunnels, looking with the eyes and touching with both hands. Not only is it labor-intensive, but it is also difficult to accurately capture deformation trends. Now, the monitoring system has become our 'thousand mile eye'. Once the monitoring tower data is abnormal, the system will automatically alarm, and we can notify the on-site work area in a timely manner to achieve efficient repair, "sighed Liu Junming, the business supervisor of Taiyuan North Communication Workshop. On the larger security prevention and control network, 'digital sentinels' are also silently guarding. During the Spring Festival travel rush, the Taiyuan North Rolling Stock Depot of Taiyuan Railway Bureau has an average of over 330 trains and 18000 vehicles per day. The high-density operation of vehicles poses a significant challenge to the maintenance efficiency and accuracy of large freight trains. The application of intelligent technology has solved this problem. At the centralized monitoring center of TFDS (Intelligent Recognition System for Truck Fault Trackside Image Detection), maintenance personnel are using the TFDS dynamic detection system to process thousands of photos collected at high speed by trackside equipment. Wang Jiahong, the person in charge of the dynamic monitoring operation site at Taiyuan North Rolling Stock Depot, said: "The TFDS intelligent recognition system can classify and identify faults in various parts of freight trains, achieving high-speed photography, quick judgment, and rapid recognition. It not only reduces the workload of operators, but also greatly improves the accuracy of fault recognition. ”(New Society)
