Description

Technical Field

[0001] This utility model relates to an auxiliary monitoring device, and more particularly to an auxiliary monitoring device for a railway natural disaster and foreign object intrusion monitoring system. Background Technology

[0002] The railway natural disaster and foreign object intrusion monitoring system collects and monitors signals related to wind, rain, and foreign object intrusion along railway lines. It includes a front-end data transmission unit, wind and rain sensors, a back-end monitoring unit, and signal cables. The back-end monitoring unit collects and processes signals from the front-end data transmission unit, and the signal cables connect the two. Its applications in railways include: real-time monitoring of natural disasters, such as wind, rain, snow, and earthquakes, which may affect train operation safety. This monitoring data provides crucial information for dispatching and command, helping to implement timely countermeasures; monitoring foreign object intrusion, such as real-time monitoring of foreign object intrusion on road bridges crossing railways, ensuring railway line safety and preventing foreign objects from threatening train operation; providing alarm and emergency response information. For example, when a natural disaster or foreign object intrusion is detected, the system issues an alarm and initiates emergency response through coordinated control of the signal system, effectively preventing or reducing the impact of disasters on railway train operation safety; and ensuring train operation safety, such as providing support for train dispatching and maintenance management through real-time monitoring and alarms, ensuring safe train operation in various environments.

[0003] In practical applications, existing railway natural disaster and foreign object intrusion monitoring systems only monitor servers and monitoring unit equipment in real time, lacking real-time monitoring and system integration of outdoor cables, wind and rain sensors, and the status of foreign objects in the power grid. This results in the inability to quickly determine the fault location when a fault occurs, causing long fault latency and hindering maintenance departments from monitoring and analyzing equipment. When existing disaster monitoring systems malfunction, the fault location is unclear, requiring the entire maintenance and management unit to be mobilized to troubleshoot, which is time-consuming and labor-intensive. Furthermore, electrical performance testing of signal cables can only be conducted on-site, without real-time monitoring of the signal cable's electrical performance.

[0004] While modern monitoring systems aim to improve accuracy by integrating various sensors such as vibration sensors, 3D lidar, and video, the lack of automated monitoring equipment for the power supply of these sensors leads to widespread false alarms and missed alarms due to power failures. Currently, manual inspection and troubleshooting are still the primary methods, which are demanding, labor-intensive, and inefficient, while also compromising system reliability and performance. Furthermore, different railway lines and geographical environments impose varying requirements and loads on monitoring systems. Therefore, adapting to different needs and geographical environments, especially when manual inspection is unsuitable, and developing automated fault detection, troubleshooting, and alarm mechanisms, is a crucial issue that urgently needs to be addressed.
