High-speed railways must conduct comprehensive monitoring of various possible disasters (such as strong winds, heavy rain, heavy snow, earthquakes, and other natural disasters as well as landslides, rockfalls, and foreign invasions), and establish safety early warning systems and emergency disaster relief systems. There are generally the following alarm devices on high-speed rails:
Smoke monitoring alarms all trains are non-smoking and trains have sensors. If a passenger smokes cigarette smoke, the sensor senses it and the driver knows there is smoke in the compartment and then chooses a suitable place to park.
Train speed warning The train speed sensor is installed at the bottom of the train and can accurately capture the train speed. When the train exceeds a certain limit speed, the network control system can alarm in real time and the driver needs to adjust the operating speed immediately.
Bearing overheating alarm The train temperature sensor monitors the bearing. Once the temperature is too high, the network control system will immediately report an alarm to prevent the bearing temperature from being too high to prevent the accident.
Foreign objects set up a monitoring and warning system in the sections where there may be idlers entering high-speed railways, and roads where rockfall may occur. Metal protection nets, foreign material monitoring networks, and monitoring and alarm systems are installed to ensure that invaded information is transmitted to the comprehensive dispatching center in a timely manner to control the operation of trains.
In rainstorm, additional rain sensors were installed in areas where the camera's sensor annual precipitation was greater than 200 mm, and three-level rainfall warnings were set to implement measures such as warning, speed limit, and outage. In places where necessary, additional cameras, inclinometers, strain gauges, detection nets and other sensors were added to monitor subgrade disasters.
Seismic automatic cut-off of contact network power After an earthquake occurs, the railway seismic monitoring system will analyze and determine the monitored seismic signals in a timely manner. If the pre-warning level is reached, the power of the contact network of the relevant section will be automatically cut off, and the train running on this section will be stopped by the ATC signal, and the train running in the adjacent section will no longer enter the disaster area.
Strong Wind Setting Wind Speed ​​Detector Wind speed detectors are required along the railway lines. These detectors are generally installed in oversized bridges, stations, substations, and tuyere areas. When strong winds are detected, the trains need to be immediately controlled.
