Description

Technical Field

[0001] This utility model belongs to the field of locomotive early warning technology, and in particular relates to a real-time early warning system for the status of a Harmony type locomotive 6A system when it is coupled together. Background Technology

[0002] Harmony-type locomotives are high-power electric locomotives widely used in China's railways. They are characterized by strong traction and high operating efficiency. They are often used in multiple-unit configurations to meet the needs of large-capacity and long-distance transportation. This means that multiple locomotives are connected to form a multiple-unit combination during operation, with one locomotive serving as the main locomotive operated by the crew, while the other multiple-unit locomotives are in an unattended state.

[0003] During the operation of Harmony locomotives in double-unit formation, the running gear monitoring information and fire prevention monitoring information of the double-unit locomotive (in its unattended state) cannot be transmitted to the main locomotive. When the running gear monitoring information of the double-unit locomotive is abnormal or a fire occurs, the main locomotive cannot detect it in time, posing a potential safety hazard: for example, abnormal axle temperature may lead to bearing seizure or even breakage; abnormal fire prevention poses a fire safety risk. To address these issues, the following solutions are proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a real-time early warning system for the status of a Harmony type locomotive when the 6A system is coupled together. By transmitting the 6A monitoring information of the coupled locomotive to the main locomotive via the coupling line and displaying it, the crew of the main locomotive can promptly detect and handle alarm anomalies in the running gear and fire monitoring of the coupled locomotive. This solves the problem that in existing Harmony type locomotives, the 6A monitoring information of the coupled locomotive cannot be transmitted to the main locomotive when coupled together, which leads to the main locomotive's inability to detect abnormalities in the coupled locomotive in a timely manner and the potential for traffic safety accidents.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a real-time early warning system for the status of a Harmony-type locomotive 6A system during multiple-unit operation. The early warning system includes:

[0007] The information reading module is used to read the running gear monitoring information, fire prevention monitoring information and video information of the vehicle's 6A system;

[0008] The first data processing module, connected to the information reading module, is used to distribute the read vehicle 6A information to multiple reconnection sockets;

[0009] The transmission module includes a modified reconnection line, which is equipped with an Ethernet communication line to transmit the 6A information of this vehicle to other reconnected vehicles through the reconnection socket, and at the same time read the 6A information of other reconnected vehicles.

[0010] The second data processing module, connected to the transmission module, is used to distribute the read information of the multiple-unit locomotive 6A to the driver's cab display module of the locomotive.

[0011] The display module is installed in the driver's cab at both ends of the locomotive and at both ends. It is used to display the 6A information of other locomotives that are coupled together. When the monitoring information of other locomotives is abnormal or there is a fire, the locomotive can issue a real-time warning.

[0012] Furthermore, the information reading module is connected to the reserved information transmission interface of the locomotive 6A system via an Ethernet cable to read 6A information.

[0013] Furthermore, the first data processing module adopts the YT / SJCL-1 locomotive multiple-unit data processor, which has 6 100Mbps adaptive ports, can distribute the 6A information of this locomotive to 4 external multiple-unit sockets, and any multiple-unit socket can output the 6A information of this locomotive.

[0014] Furthermore, the modified reconnection line in the transmission module adds two sets of Ethernet communication lines, one set for outputting the 6A information of this vehicle and the other set for reading the 6A information of other vehicles reconnected.

[0015] Furthermore, the second data processing module adopts the YT / SJCL-1 locomotive multiple-unit data processor, which reads the 6A information from any of the four multiple-unit sockets connected to other cars and distributes one signal to the display modules of the driver's cab at end I and end II.

[0016] Furthermore, the display module is a 6A display screen, which is installed in the driver's cab at both ends of the locomotive and the driver's cab at both ends, and can display the 6A information of other locomotives coupled together in real time.

[0017] This utility model has the following beneficial effects:

[0018] This invention enables the transmission and display of 6A monitoring information from the coupled locomotives to the primary locomotive via the coupling line during operation. This allows the primary locomotive crew to promptly detect and address alarm anomalies in the running gear and fire monitoring of the coupled locomotives. It solves the problem of unattended operation of coupled locomotives without the transmission of relevant safety information to the primary locomotive, avoids potential safety hazards caused by undetected axle temperature abnormalities or fires, and ensures the safety of coupled locomotive operation.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
