A railway network security risk monitoring device according to claim 3, characterized in that: The output ends of the two second motors (304) are respectively fixedly connected to the middle of the top ends of the two fans (308); the bottom ends of the two second brushes (307) are respectively in contact with the top ends of the two filters (302); one end of the connecting pipe (309) is respectively connected to the inner side walls of the two heat dissipation pipes (305); and the other end of the connecting pipe (309) is connected to the inside of the collection box (3010).

7. The railway network security risk monitoring device according to claim 1 is characterized by: The monitoring body (106) includes sensors and probes, a data collector, a risk assessment engine, an alarm system, a processor and a response system. The sensors and probes are installed at key nodes of the railway network to collect data such as network traffic and system logs. The data collector is used to collect data collected by the sensors and probes and ensure that the data can be transmitted to the processor. The alarm system is used to ensure that relevant personnel can be notified in time when a safety event is monitored. The response system is used to take corresponding actions when a safety event is detected.

8. The monitoring method of a railway network security risk monitoring device according to claim 1 is characterized by: The following steps are involved: S1. Deploy sensors and probes at key nodes of the railway network, and use data collectors to collect network traffic and system logs collected by sensors and probes, transmit the collected data to the processor, set the alarm threshold and notification method of the alarm system, and set the corresponding system to automatic response mode; S2. Sensors and probes continuously monitor the network activities and system status of the railway network, collect relevant data, transmit the collected data to the processor through the network interface, use the processor to clean and format the collected data, use the risk assessment engine to analyze the processed data, identify potential security threats and vulnerabilities, and generate security risk reports and statistical analysis results based on the analysis results; S3. When a high-risk event is detected, the alarm system will trigger an alarm and notify the security administrator. At the same time, the response system will take corresponding security measures according to the preset strategy, such as isolating the problematic system part, changing the security strategy, etc. S4. Regularly maintain and upgrade the device to ensure the overall performance and safety of the device. Regularly conduct security audits on the entire device to evaluate the effectiveness and compliance of the monitoring device, and optimize the monitoring system and response measures based on the audit results and new security threats; S5. When the device is working, the fixing frame (105) at the bottom end of the cover plate (101) drives the screw rod (1013) to rotate, so that the slider (1018) can drive the first brush (1016) to move, and the upper end surface of the monitoring body (106) is cleaned. At the same time, the water pump (204) is turned on so that the coolant can circulate in the serpentine water pipe (203), heat exchange is performed on the heat in the housing (103), and preliminary heat dissipation is performed on the heat in the first motor (104); S6, using the second motor (304) to drive the fan (308) to rotate, so that the heat generated in the housing (103) is discharged through the heat dissipation pipe (305). At the same time, during the rotation of the fan (308), the second brush (307) is driven to rotate. As the second brush (307) rotates, the dust adhering to the filter (302) is swept off. The axial flow fan (3011) in the connecting pipe (309) is opened to collect the dust swept off by the second brush (307), and the collected dust is uniformly collected in the collection box (3010).
