[0020] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the application scenario of the solution of the present application is first described below.

[0021] For heavy-load trains, many technical aspects such as traction system performance, braking system performance, longitudinal dynamics performance of trains, strength of locomotives and their components, and reasonable operation methods will affect the safety of train operation. Especially for 20,000-ton heavy-load trains, the important indicator of safe operation is longitudinal dynamics performance, including braking performance, coupler force and longitudinal acceleration level. In fact, during the operation of heavy-load trains, not only the line conditions change frequently, but also the operating state changes constantly, and they will be affected by various forces, including traction, resistance, impact, etc. The train cannot always maintain uniform motion during operation, and there is a longitudinal gap between the two adjacent vehicles inside the train. Affected by the driver's operating conditions, the synchronous control performance of the train and the braking wave speed, the speed of the two adjacent vehicles is also different, so the coupler force of the two adjacent vehicles and the magnitude and direction of the longitudinal acceleration of the vehicle will be different. This difference will cause the coupler to make complex relative movements in the entire train, which is easy to generate large coupler force and longitudinal acceleration. These forces will have a direct impact on the body and structure of the train. If the force condition exceeds the design tolerance of the train, it may cause vibration, displacement or deformation of the train.

[0022] At present, the stress condition of heavy-load trains is judged only by human feeling, which cannot accurately reflect the actual stress condition of the train. Moreover, everyone's feeling is different, and there is no unified standard, so it is impossible to accurately and real-time measure, display and record the actual stress condition of the train. Therefore, the safety of locomotive operation will be reduced.

[0023] In order to solve the technical problems mentioned above, the present disclosure provides a locomotive data collection system, method, device, medium and product. In the present disclosure, the locomotive data collection system includes a data collection module, a data processing module and a data display module; the data collection module includes a plurality of collection submodules, and the plurality of collection submodules are respectively installed on the locomotive's coupler, axle box, bogie and body to collect data, obtain locomotive measurement data, and send the locomotive measurement data to the data processing module; the data processing module is used to perform digital signal analysis on the locomotive measurement data to determine the locomotive operation data of the locomotive operation status; the data display module is used to display the locomotive operation data. By installing a variety of collection submodules at different positions of the locomotive, a distributed collection of locomotive forces can be achieved, and the collected data can be processed and displayed, and the locomotive force conditions can be synchronized to the operator end, thereby improving the quality of locomotive data and the accuracy of operation. Therefore, the safety of locomotive operation can be improved.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, and to fully understand and implement how the present disclosure applies technical means to solve technical problems and achieve the corresponding technical effects, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure.

[0027] Embodiment 1 Figure 1 The structure diagram of a locomotive data collection system provided by the present disclosure is shown in FIG. Figure 1 As shown, the system includes: a data acquisition module 100, a data processing module 200 and a data display module 300.

[0028] The data acquisition module 100 includes a plurality of acquisition submodules 110 , which are respectively installed on the coupler, axle box, bogie and body of the locomotive to collect data, obtain locomotive measurement data, and send the locomotive measurement data to the data processing module 200 .

[0029] Specifically, in this embodiment, multiple measuring points are set on the coupler, axle box, bogie and body of the locomotive, and a corresponding acquisition submodule is installed at each measuring point, which can improve the accuracy of data acquisition. After collecting the locomotive measurement data, the acquisition submodule can send the data to the data processing module 200 for further analysis. Among them, the acquisition submodule can be a sensor.

[0030] The data processing module 200 is used to perform digital signal analysis on the locomotive measurement data to determine the locomotive operation data of the locomotive operation status.

[0031] Specifically, the collected locomotive measurement data can be analyzed by digital signals to obtain locomotive operation data, such as coupler force, coupler swing angle, relative displacement between car body and frame, longitudinal acceleration of car body, etc. This allows the operator to understand the current force condition of the locomotive based on the locomotive operation data and make corresponding operation operations, thus improving the accuracy of the operation.

[0032] The data display module 300 is used to display the locomotive operation data.

[0033] Specifically, the locomotive operation data is visualized and the locomotive stress condition is synchronized to the operator end, so that the operator can more conveniently understand the current locomotive stress condition, thereby improving the safety of locomotive operation.

[0034] In the present disclosure, the locomotive data collection system includes a data collection module, a data processing module and a data display module; the data collection module includes a plurality of collection submodules, and the plurality of collection submodules are respectively installed on the coupler, axle box, bogie and body of the locomotive to collect data, obtain locomotive measurement data, and send the locomotive measurement data to the data processing module; the data processing module is used to perform digital signal analysis on the locomotive measurement data to determine the locomotive operation data of the locomotive operation status; the data display module is used to display the locomotive operation data. By installing a variety of collection submodules at different positions of the locomotive, distributed collection of locomotive forces can be achieved, and the collected data can be processed and displayed, and the locomotive force conditions can be synchronized to the operator end, thereby improving the quality of locomotive data and the accuracy of operation. Therefore, the safety of locomotive operation can be improved.

[0035] Embodiment 2 On the basis of the above embodiment, the data acquisition module includes a coupler strain gauge acquisition submodule, a vibration acceleration acquisition submodule, a cable displacement acquisition submodule, a laser displacement acquisition submodule, a locomotive pressure acquisition submodule and a speed acquisition submodule; the locomotive measurement data includes the longitudinal force of the locomotive, the vibration data between the wheel and rail, the lateral offset of the coupler, the offset of the bogie, the vertical offset of the coupler, the air cylinder pressure, the vehicle pipe pressure and the current locomotive speed. The coupler strain gauge acquisition submodule is installed on both sides of the coupler to collect the longitudinal force of the locomotive; the vibration acceleration acquisition submodule is installed on the axle box and the bogie to collect the vibration data between the wheel and rail of the locomotive; the cable displacement acquisition submodule is installed on the coupler and the bogie to collect the lateral offset of the coupler and the offset of the bogie; the laser displacement acquisition submodule is installed on the coupler to collect the vertical offset of the coupler; the locomotive pressure acquisition submodule is installed on the car body to collect the air cylinder pressure and vehicle pipe pressure of the locomotive; the speed acquisition submodule is installed on the car body to collect the current locomotive speed of the locomotive.

[0036] Specifically, the strain gauge is a component composed of a sensitive grid and other components for measuring strain. When in use, it is firmly attached to the measuring point of the component. When the component is subjected to force, the measuring point is strained, and the sensitive grid is deformed accordingly, causing its resistance to change. The resistance change is then measured by a special instrument and converted into the strain value of the measuring point. Placing the strain gauge on both sides of the coupler can accurately collect the stress changes of the coupler, and it is more convenient to collect using strain gauges. When the locomotive vehicle is running on the railway line, the wheel and rail interact with each other, and vibration is generated due to the unevenness of the line. The vibration acceleration of the axle box and the vibration acceleration of the bogie can reflect the vibration state between the locomotive wheel and rail. Affected by the position and movement changes of the locomotive coupler, it is more convenient and convenient to collect the lateral offset of the coupler using a pull-wire displacement sensor. The laser displacement sensor can be installed on the couplers at the head and tail of the locomotive, which are less affected by movement changes, and the laser collection data is more accurate.

[0037] Embodiment 3 Based on the above embodiment, the data acquisition module includes multiple data acquisition instruments and multiple switches.

[0038] Multiple collectors are installed in the air-conditioning side cabinet and the reconnection door tool cabinet of the vehicle body, which are used to collect locomotive measurement data and upload it to the switch; multiple switches are installed in the signal cabinet of the vehicle body, which are used to transmit the locomotive measurement data to the data processing module.

[0039] Specifically, the data collector has multiple data channels, so each data collector can be connected to multiple data collection submodules. The data collected by the data collection submodules of all measurement points are collected through data cables to the corresponding connected data collectors, and connected to switches through network cables to form a distributed data collection network, which can realize remote background viewing and dumping functions.

[0040] Embodiment 4 Based on the above embodiment, the data processing module 200 includes an industrial computer, a router and a signal analysis submodule.

[0041] The router is connected to the switch through a network and is used to forward the locomotive measurement data to the industrial computer; the signal analysis submodule is used to perform digital signal analysis on the locomotive measurement data and determine the locomotive operation data of the locomotive operation status; the industrial computer is used to store the locomotive operation data.

[0042] Specifically, the signal analysis submodule performs digital signal analysis and calculates the locomotive operation data in real time, including coupler stress, coupler swing angle, relative displacement between the car body and the frame, and longitudinal acceleration of the car body, etc. The industrial computer can collect, transmit, store and pre-process the locomotive operation data in real time.

[0043] Embodiment 5 Based on the above embodiments, Figure 2 Another structural schematic diagram of a locomotive data collection system provided by the present disclosure. Figure 2 As shown, the system further includes an early warning module 400 .

[0044] The early warning module 400 is used to obtain locomotive operation data; make early warning judgments on the locomotive operation data according to the standard operation indicators of the locomotive; and send an early warning signal to the data display module when it is determined that the locomotive operation data does not meet the standard operation indicators.

[0045] Specifically, during the operation of the locomotive, the operating state may change continuously due to changes in line conditions. The locomotive will be affected by various forces, including traction, resistance, impact, etc., which will cause the locomotive operation data to change. At this time, the locomotive operation data may not meet the standard operation index, that is, the locomotive has an abnormal operation safety situation. After determining the index, the early warning module sends an early warning signal to the data display module, and the data display module displays the early warning signal to achieve the effect of prompting the operator.
