It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0038] During long-distance railway transportation, vehicles must be secured to the train flatbed using reinforcement equipment to ensure transport safety. However, due to vibrations and turns during long-distance transport, vehicles may become loose. Current technology typically relies on manpower for on-site inspections during train stops, which suffers from incomplete inspections, numerous blind spots, high manpower costs, and low efficiency. Furthermore, the lack of real-time monitoring means that the vehicle reinforcement status cannot be monitored in real time while the train is in motion, making it difficult to detect and address loosening and other abnormalities promptly. Therefore, there is an urgent need to develop a system capable of real-time monitoring of vehicle status and rapid location of problematic vehicles.

[0039] Based on this, an exemplary embodiment of this application provides a vehicle status monitoring and early warning system for railway transportation, including a vehicle status monitoring device, a server, and a display terminal. The vehicle status monitoring device is installed on or around the monitored vehicle and can monitor and acquire vehicle status information in real time. The acquired vehicle status information is sent to the server in real time via a wireless network. After receiving the vehicle status information and analyzing and processing it, the server promptly uploads the information to the display terminal, which displays the analysis and processing results. In this way, during train operation, the vehicle status can be monitored in real time, and abnormalities such as loosening or displacement can be detected in a timely manner. Through data analysis and positioning, the specific location of the problematic vehicle can be quickly determined.

[0040] Example 1:

[0041] An exemplary embodiment of this application provides a vehicle status monitoring and early warning system during railway transportation. In the railway transportation diagram, vehicles are fixed to the transportation platform by baffles 100 and chains. Figure 1As shown, the system includes: a vehicle status monitoring device, a server, and a display terminal; the vehicle status monitoring device is connected to the server via a wireless network; the server is connected to the display terminal via a wireless network; preferably, the wireless communication method can be ZigBee wireless communication. The vehicle status monitoring device is installed on or around the monitored vehicle to acquire vehicle status information; the vehicle status information includes at least one of the following: chain fastening status information, baffle 100 status information, vehicle position status information, and vehicle attitude information. The vehicle status monitoring device is used to send the vehicle status information to the server; the server is used to receive the vehicle status information and perform analysis and processing; the display terminal is used to receive and display the analysis and processing results. In this way, during train operation, the vehicle status can be monitored in real time, and abnormalities such as loosening and displacement can be detected in a timely manner; through data analysis and positioning, the specific location of the problematic vehicle can be quickly determined.

[0042] like Figure 4 As shown, the vehicle condition monitoring device includes a chain fastening condition monitoring device, a baffle condition monitoring device, a vehicle position condition monitoring device, and a vehicle attitude monitoring device. The chain fastening condition monitoring device is installed at the chain securing the vehicle. This device includes multiple fiber optic force sensors to monitor the chain tension in real time, enabling real-time monitoring of the tension value of the chain securing the vehicle to detect whether the chain is loose and to identify potential chain loosening issues. The baffle condition monitoring device includes multiple fiber optic acoustic signature sensors 110 to monitor the mechanical vibration of the baffle 100 in real time; such as... Figure 5 and 6 As shown, the fiber optic acoustic signature sensor 110 is fixed on the side of the baffle 100 away from the vehicle tires, capable of collecting mechanical vibration data caused by unstable fixing. After processing and analysis by the server, the collected data can determine the vehicle's swaying on the transport platform. The vehicle position status monitoring device includes multiple positioning sensors 120, which are installed at the rear of each vehicle to monitor the spacing between the vehicles in real time.

The warning device has the function of issuing an alarm. The warning device can be an alarm, signal light, or horn, which can issue an alarm through sound or signal lights. The alarm is configured into multiple warning levels based on whether the vehicle status information exceeds preset values. For example, the alarm includes various methods such as sound, light, and electricity; when the warning device is a signal light, it issues an alarm through flashing lights. The degree of danger of the warning information can be preset, for example, setting red for a level one alarm and orange for a level two alarm. When the warning device is a horn, it issues an alarm through sound. Of course, flashing lights and sound can also be combined to issue an alarm.
