Description

Technical Field

[0001] The present application relates to the technical field of railway locomotive lighting fixtures, and in particular to a railway locomotive headlamp. Background Art

[0002] At present, the headlights of railway locomotives in operation are equipped with two working states: full light and half light according to the standard, and the illumination of the lamps is not adjustable in either working state.

[0003] As the use time of the lamp increases, the overall illumination gradually decreases, which greatly reduces the visibility distance of the driver and passengers at night and easily causes driving safety hazards. In addition, when the lights of online operating locomotives are running during the day, they generally use the light-off or half-light working mode. When there is a tunnel or the light dims on rainy days during the day, it is necessary to manually switch to the full light state to enhance the lighting. This method increases the workload of the driver and passengers to a certain extent.

[0004] Especially when the vehicle is running in semi-light mode, if the driver and passengers enter a tunnel or on rainy days without switching the lighting mode, it is very easy to cause visual tension and fatigue, affecting driving safety.

[0005] Therefore, there is an urgent need for a motorcycle lamp body that can adjust the illumination in multiple gears and automatically switch the lighting state. Utility Model Content

[0026] In order to make the purpose, implementation methods and advantages of the present application clearer, the exemplary implementation methods of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, not all of the embodiments. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.

[0027] It should be noted that the brief descriptions of terms in this application are only for the purpose of facilitating the understanding of the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and usual meanings.

[0028] In the specification and claims of this application and the accompanying drawings, the terms "first," "second," "third," etc. are used to distinguish similar or similar objects or entities, and are not necessarily intended to limit a particular order or sequence, unless otherwise noted. It should be understood that the terms used in this manner are interchangeable under appropriate circumstances.

[0029] The terms "comprise," "include," and "have," and any variations thereof, are intended to cover but not exclude inclusion; for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0030] Before explaining the railway locomotive headlight provided by the embodiment of the present application, the application scenario and implementation environment of the embodiment of the present application are first introduced.

[0031] At present, the headlights of railway locomotives in operation are equipped with two working states: full light and half light according to the standard, and the illumination of the lamps is not adjustable in either working state.

[0032] As the use time of the lamp increases, the overall illumination gradually decreases, which greatly reduces the visibility distance of the driver and passengers at night and easily causes driving safety hazards. In addition, when the lights of online operating locomotives are running during the day, they generally use the light-off or half-light working mode. When there is a tunnel or the light dims on rainy days during the day, it is necessary to manually switch to the full light state to enhance the lighting. This method increases the workload of the driver and passengers to a certain extent.

[0033] Especially when the vehicle is running in semi-light mode, if the driver and passengers enter a tunnel or on rainy days without switching the lighting mode, it is very easy to cause visual tension and fatigue, affecting driving safety.

[0034] Therefore, there is an urgent need for a railway locomotive headlamp that can adjust the illumination intensity in multiple gears and automatically switch the lighting state.

[0035] Based on this, the present application provides a railway locomotive headlight and its control method, which realizes light attenuation compensation and automatic switching of light status according to the brightness of the locomotive operating environment. The headlight can keep the light intensity close to a constant value at all times, and reduce the impact of misoperation caused by frequent switching of light status by drivers and passengers, thereby safeguarding driving safety.

[0036] Next, the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems will be described in detail through embodiments and in conjunction with the accompanying drawings. The various embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, not all of them.

[0039] The illumination adjustment switch 8 and the controller 7 are both connected to the lamp body;

[0040] The lamp body includes a light-emitting module 1, a mounting frame 2, a support frame 3, a power supply component 4 and a lamp body connector 6.

The lamp body is fixedly connected to the front of the vehicle through the mounting frame 2.

[0041] Figure 2is a schematic structural diagram of a controller 7 shown in an exemplary embodiment of the present application. Figure 3 1 is a structural diagram of a light intensity adjustment switch 8 shown in an exemplary embodiment of the present application.

[0042] In one possible implementation, Figure 2 and Figure 3 As shown, the specific structure of the railway locomotive headlight is as follows;

[0043] The device includes a lamp body, a controller 7, and an illumination adjustment switch 8. The illumination adjustment switch 8 is connected to the lamp body via a cable and has eight adjustment positions. The switch periodically adjusts the positions to compensate for illumination attenuation. The lamp body is equipped with an illumination sensor assembly 5, which is connected to the controller 7. The illumination values ​​collected by the sensor are combined with a program set within the controller 7 to automatically control the switching of the lighting state.

[0044] In one possible implementation, Figure 2 and Figure 3 As shown, the light intensity sensor assembly 5 of the above-mentioned lamp body is fixed to the light-emitting module 1 by screws and structural parts; the light-emitting module 1 is fixed to the mounting frame 2 by screws and related structural parts; the power supply assembly 4 and the lamp body connector 6 are fixed to the support frame 3 by screws; the mounting frame 2 and the support frame 3 are fixedly connected by screws and nuts; the controller 7 is installed at the corresponding position in the driver's cab and is connected to the lamp body connector 6 through the control cable 9; the light intensity adjustment switch 8 is installed at the corresponding position in the driver's cab and is connected to the power supply assembly 4 through the switch cable 10.

[0045] In a possible implementation, a 485 communication interface is further provided at the output end of the power supply assembly 4 .

[0046] In a possible implementation, a control cable connector 11 and a controller power supply port 12 are provided on the controller 7 , and the control cable connector 11 is connected to the lamp body connector 6 .

[0047] In a possible implementation, the light intensity adjustment switch includes a mounting plate 13 , a light intensity adjustment knob 14 , and a switch cable connector 15 , and the switch cable connector 15 is connected to the power supply assembly 4 .

[0048] It should be understood that although the steps in the flowcharts of the above embodiments are shown in sequence as indicated, these steps are not necessarily executed in the order indicated.

Moreover, at least a portion of the steps in the flowcharts of the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times. The order of execution of these steps or stages is not necessarily sequential, but can be executed in rotation or alternation with other steps or at least a portion of steps or stages in other steps.

[0049] Corresponding to the aforementioned embodiment of a railway locomotive headlight and adopting the same technical concept, the present application also provides an embodiment of a railway locomotive headlight control method.

[0050] It can be seen that the lamp body in some embodiments of the present application is designed with a certain margin for light intensity adjustment. The gradual attenuation of light intensity can be compensated by increasing the gear position of the light intensity adjustment switch 8, ensuring that the light intensity value is always maintained at a certain level. At the same time, a 485 communication interface is left at the output end of the lamp body power supply component 4 to expand related functions, and the current gear can be set remotely online through the data platform in the future. In addition, a light intensity sensor is installed inside the lamp body. When a sudden change in the external ambient light is detected, the internal program of the connected controller 7 controls the automatic switching of the light state of the lamp body (the switching between turning off the light and full light state or the switching between full light and half light state can be selected according to the actual needs of the customer). This solves the problem that drivers and passengers need to frequently switch the light state due to changes in the ambient light while driving, and effectively ensures the safety and reliability of the locomotive while reducing their workload.

Each module in the above-described railway locomotive headlight control method can be implemented in whole or in part via software, hardware, or a combination thereof. Each of these modules can be embedded in or independent of a processor in a computer device in hardware form, or stored in a computer device memory in software form, allowing the processor to call and execute the corresponding operations of each module.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
