Disaster Prevention Monitoring and Disaster Rating Table
The overall composition of disaster prevention and safety monitoring consists of natural disasters (wind, rain, flood, earthquake), rail temperature and fire, and sudden accidents. After the use of professional measuring instruments, the above factors are understood to be regulated, and the processed disaster warning information, speed limit information, outage information, etc. are provided for adjustment of the dispatch center operation plan, traffic control, emergency rescue, and maintenance. As the basis, ensure that the passenger dedicated line trains are safe, efficient and comfortable.
1 Gale: jeopardizes traffic safety and makes trains running at high speeds unstable. When the critical state is reached, the train is easy to turn over and upside down. In combination with the terrain, a wind wall is installed on the windward side of the line to monitor the wind speed value of the dangerous section, according to the wind speed value, Train running conditions and line facilities status limit the speed of the train. The monitoring of wind direction wind speed is generally performed using a wind direction anemometer to perform operations. Through the records it has implemented and uploading the measurement results to the plant base to analyze the data, the change of wind direction wind speed is known, and the change process is used to make early decisions. Corresponding protective measures.
2Rain and flood: easily lead to various disasters, such as water accumulation, landslides, mudslides, landslides, and floods crossing bridges and roadbeds, etc., to monitor the rainfall and flood water level values ​​in dangerous areas, and to reflect on-site disasters in real time, based on monitored values ​​and lines. The status of facilities, such as the timely inspection of the line and the speed limit of the train. The measurement of rainfall is the use of a rainfall monitor, through which he calculates the amount of rainfall, according to the different levels of rainfall, to determine the natural disasters that will be triggered, the following table is the relationship between rainfall and natural disasters:
