Description

Technical Field

[0001] The present invention belongs to the technical field of natural disaster monitoring, and in particular to a debris flow early warning and emergency treatment system and method. Background Art

[0002] In the railway transportation system, the potential hazards of debris flow disasters are particularly prominent. It not only directly threatens the physical safety of railway facilities, but also seriously interferes with the normal operation of trains. For example, when a debris flow occurs, a large amount of fluid mixed with soil, rocks and water rushes down the hillside or valley at a very fast speed, which can quickly cover the railway line and destroy key structures such as roadbeds, bridges, and tunnels, resulting in railway interruptions, train derailment or even overturning, which in turn affects the travel safety of passengers and the timely transportation of goods, and has a profound impact on economic and social activities. In order to avoid the impact of mudslides on railway traffic, detection devices are often deployed along the railway. The detection devices are used to obtain information related to mudslides in the sub-region, such as rainfall, mud level, video and other information, and transmit the rainfall, mud level, video and other information to the detection center. By judging whether the rainfall and mud level exceed the preset thresholds, it is judged whether a mudslide disaster will occur in this area. If a mudslide disaster occurs, appropriate preventive measures and warnings are taken, and the dispatching station in this area is prompted to dispatch the trains involved. Although this method can predict the occurrence of mudslide disasters to a certain extent, the evaluation method of judging whether the rainfall and mud level exceed the preset thresholds during the prediction process is single, and it is easy to make misjudgments, which in turn causes delays or suspension of trains involved in this area, causing great economic losses.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention proposes a debris flow early warning and emergency handling system. The system realizes comprehensive monitoring and rapid response to debris flow disasters by integrating multiple modules such as data acquisition, real-time analysis, mobile warning and alarm linkage. The data acquisition module can obtain various key parameters of the debris flow area in real time, such as rainfall, soil moisture, debris flow velocity, etc. The front-end networking unit can still independently generate and transmit early warning signals under abnormal communication conditions, ensuring the timely delivery of early warning information and avoiding the problem of early warning failure caused by communication interruption. The data analysis module uses advanced algorithms to quickly process the real-time acquisition parameters. By comparing with the preset level threshold, the severity of the debris flow can be accurately judged, and corresponding level warning data can be generated, thereby improving the accuracy of the early warning. The alarm and linkage module can quickly receive and analyze the early warning signal and send warning information to the user terminal and the mobile warning receiving module. The user can take emergency handling measures in time according to the received warning information to avoid the occurrence of railway traffic accidents and improve the safety of train operation.

[0015] Furthermore, the system ensures the accuracy and consistency of real-time acquisition parameters through the data processing unit. The data cleaning unit can sort and process the parameters based on the time series, effectively eliminate abnormal and invalid data, and improve the data quality. The data conversion unit further organizes the processed data into real-time parameters of debris flow in a unified format. The establishment of the early warning analysis unit greatly enhances the early warning capability of the system. The level threshold setting unit allows users to flexibly set different levels of debris flow early warning thresholds according to actual needs, thereby realizing accurate early warning of debris flow disasters of different scales and degrees of harm. The real-time data analysis unit can receive and process the real-time parameters of debris flow in real time, and quickly generate debris flow level data by comparing with the level threshold, providing a scientific basis for emergency treatment. The close combination of the data processing unit and the early warning analysis unit makes the entire data analysis process more efficient and accurate. The automated processing of data cleaning, conversion and analysis greatly shortens the early warning response time and improves the real-time and reliability of the system. Therefore, the debris flow early warning and emergency treatment system and method not only improves the accuracy and timeliness of the early warning, but also enhances the flexibility and practicality of the system.

[0016] Furthermore, the system significantly improves the alarm capability of the system through the coordinated work of the alarm output unit, the multi-terminal alarm unit and the linkage alarm unit. The alarm output unit can receive the graded alarm data in real time and quickly send the second alarm signal to the multi-terminal alarm unit and the mobile alarm receiving module, ensuring the timely transmission of the warning information. The multi-terminal alarm unit can use a variety of channels to alarm the debris flow, so that the relevant personnel can receive the warning information in the first time and take corresponding countermeasures. The linkage alarm unit is specifically responsible for receiving the first warning signal and sending the first debris flow warning signal to the user terminal, providing an earlier warning for emergency handling, improving the accuracy and timeliness of the alarm, and enhancing the traceability and controllability of the system.

[0017] Furthermore, the recording and feedback unit of the system makes the system's alarm process more traceable and controllable.

The method realizes accurate early warning and rapid response to debris flow disasters by real-time collection of debris flow related parameters and processing and analysis. The method can generate level warning data based on the comparison between the real-time collected parameters and the preset level threshold, providing a scientific basis for emergency handling. When the on-site communication is abnormal, the method can use the preset first-level warning threshold for comparison to generate a first warning message, ensuring that a warning can be issued in time even in extreme cases. The method can send a first warning message and a second warning message to the user terminal respectively based on the first warning message and the level warning data, and remind relevant personnel to take countermeasures through various channels, effectively improving the prevention and response capabilities of debris flow disasters in railway transportation.
