Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of locomotive monitoring, in particular to a shunting yard safety inspection and management system. Background Art
[0002] With the rapid development of railway transportation, the operational safety and performance stability of locomotives, as the primary power equipment for railway transportation, have become extremely important. If the rail surface is contaminated by rainwater, oil, or the locomotive power output is excessive, the wheel output torque will exceed the friction between the wheel and the rail, causing the wheels to spin. This not only affects the normal operation of the locomotive but may even damage the wheels and rails, leading to serious safety accidents. Therefore, regular locomotive inspection and maintenance are crucial. Traditional locomotive inspection methods rely on manual inspections, which are not only time-consuming and labor-intensive, but also susceptible to human factors, resulting in low accuracy and efficiency. Utility Model Content
[0003] In order to solve the above problems, the purpose of the embodiments of the present utility model is to provide a shunting yard safety inspection and management system.
[0004] A shunting yard safety inspection and management system, comprising:
[0005] The speed sensor is installed at the wheel axle of the locomotive to collect the wheel speed;
[0006] The station microcomputer is connected to the speed sensor and the GPS communication module respectively. When the speed of the locomotive increases sharply to a set threshold within a preset time, it is determined that the wheels are idling, and the station microcomputer sends an alarm to the driver's monitoring room through the GPS communication module; when the speed of the locomotive drops sharply to 0 within a preset time, it is determined that the wheels are locked, and the station microcomputer sends an alarm to the driver's monitoring room through the GPS communication module.
[0007] Preferably, the vehicle further comprises: a driver alarm module, configured to send an alarm to the locomotive driver when the wheels are spinning or locked.
[0008] According to the specific embodiments provided by the present invention, the present invention discloses the following technical effects:
[0009] The utility model relates to a shunting yard safety inspection and management system. Compared with the existing technology, the utility model monitors the wheel speed changes in real time through a speed sensor, and can promptly identify the situation of wheel locking or idling. When a wheel fails, an alarm is promptly issued to the inspection personnel, thereby improving the work efficiency of the inspection work.

[0014] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0015] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.
[0016] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
[0017] See also Figure 1-2 , a shunting yard safety inspection and management system, comprising:
[0018] The speed sensor is installed at the wheel axle of the locomotive to collect the wheel speed;
[0019] The station microcomputer is connected to the speed sensor and the GPS communication module. When the locomotive's speed increases to a set threshold within a preset time, the wheels are judged to be spinning, and the station microcomputer sends an alarm to the driver's monitoring room via the GPS communication module. When the locomotive's speed drops to zero within a preset time, the wheels are judged to be locked, and the station microcomputer sends an alarm to the driver's monitoring room via the GPS communication module. In practical applications, the present invention can utilize the DGPS communication technology built into the GPS communication module in conjunction with an electronic map to accurately locate the locomotive.
[0020] In the embodiment of the present invention, a sensor is installed at the wheel axle of the locomotive to measure the speed, and the data is transmitted to the microcomputer for analysis. Here, five speed values are taken within 1s as an example, and the speed value is taken every 20ms, which are set as A, B, C, D, and E respectively; put it into the formula The data is then taken from a limited range, K. If W > KC, it is determined to be wheel slippage and idling. If the wheel speed suddenly increases while the locomotive is in operation, the microcomputer controls appropriate remedial measures and issues a danger alarm to the driver's control room, which also stores this data in the backend. If idling is recorded three or more times within 30 minutes for the same track section (the expected frequency can be adjusted based on site conditions), this section is considered susceptible to slippage, and the dispatch office is notified to schedule a track inspection. If only one vehicle is idling on multiple sections of track, and the remaining vehicles pass through the operating route without any problems within the designated time, this vehicle is considered to require maintenance, and the dispatch office is notified to arrange for a replacement locomotive and the necessary maintenance. If the recorded speed suddenly drops to zero, it is determined to be wheel locking, and the microcomputer controls appropriate remedial measures and issues a danger alarm to the driver's control room, which also stores this data in the backend. If the same track section is recorded to have locked rails more than twice within 30 minutes (the expected frequency can also be adjusted according to on-site conditions), the friction of this section of rails is judged to be low, and the dispatching room will be notified to arrange inspections of the corresponding tracks; if only one vehicle is locked on multiple sections of rails, and the other vehicles pass through its operating route within the specified time without any problems, it is judged that this vehicle needs maintenance, and the dispatching room will be notified to arrange the corresponding maintenance.
[0021] The utility model monitors the wheel speed change in real time through the speed sensor, and can promptly identify the wheel locking or idling situation, so as to promptly alert the inspection personnel when the wheel fails, thereby improving the work efficiency of the inspection work.
[0022] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technical solution that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
