AI Technical Summary
The whistle sound of the locomotive when running at night can easily disturb the surrounding residents, and it is difficult to completely avoid misoperation by relying on driver management.
Install a controller on the locomotive to electrically interlock the headlights and the whistle to achieve automatic switching, ensuring that the whistle cannot make a sound when the headlights are turned on at night, and alternatively use the whistle to honk the whistle.
It effectively avoids noise interference to surrounding residents by locomotive driving at night, and does not affect the safety of locomotive driving.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transport locomotives in smelters, and particularly relates to a locomotive with an automatic switching function of a whistle and a headlight. Background Art
[0002] In cities, the operation of industrial facilities such as steel plants often causes noise interference to surrounding residents. Since the whistle sound of a locomotive is relatively loud during night operation, it is easy to cause problems of disturbing the residents around. And when a train is running at night, the driver is often difficult to control. Even if it is stipulated that the whistle is not applicable at night, there may still be misoperations and it cannot be completely avoided. Therefore, it is impossible to achieve the purpose of avoiding disturbing the residents only by managing the train driver, but it is necessary to solve the fundamental problem through the improvement of hardware facilities to achieve the purpose of completely avoiding misoperations. Content of the Utility Model
[0003] The purpose of the utility model is to solve the problems put forward in the above background art, and provide a locomotive with an automatic switching function of a whistle and a headlight, which realizes interlocking automatic control on the hardware facilities, so that the whistle cannot be used at night, and completely solves the problem of disturbing the residents at night.
[0004] The specific technical solution of the utility model is as follows: A locomotive with an automatic switching function of a whistle and a headlight includes a locomotive body. A set of headlights and a whistle device are installed at the front end and the rear end of the locomotive body respectively. A controller is installed at the front end and the rear end of the locomotive body respectively. Each controller is electrically connected to the corresponding headlight and whistle device. The controller is provided with an automatic switching switch, so that only the headlight or the whistle device can be turned on at the same time.
[0005] Preferably, the two controllers are communicatively connected to achieve automatic switching. When the locomotive moves forward, the controller at the front end works. When the locomotive moves backward, the controller at the rear end works.
[0006] Preferably, the whistle device includes an electric horn and a steam whistle. The controller is only connected to the steam whistle so that there is an electrical interlock between the steam whistle and the headlight.
[0007] Preferably, the electric horn is provided with a separate control button.
[0008] The beneficial effects of the utility model are as follows: By setting the controller to make the corresponding headlight and the steam whistle electrically interlocked, it is realized that the steam whistle cannot make a sound when the headlight is on; effectively avoiding the noise interference caused by the locomotive to the surrounding residents during night driving, and at the same time not affecting the driving safety of the locomotive. Description of the Drawings
[0009] Figure 1 is a schematic structural diagram of the utility model;
[0010] Figure 2This is the circuit schematic diagram of the controller of the utility model, headlight, and siren.
[0011] In the figure: 1. Locomotive body; 2. Headlight; 3. Siren. Specific implementation mode
[0012] See Figure 1-2 , this embodiment provides a locomotive with an automatic switching function between a siren and a headlight, including a locomotive body 1. A set of headlights 2 and a siren device are installed at the front and rear ends of the locomotive body 1 respectively. A controller is installed at the front and rear ends of the locomotive body 1 respectively. Each controller is electrically connected to the corresponding headlight 2 and siren device. The controller is provided with an automatic switching switch, so that only the headlight 2 or the siren device can be turned on at the same time.
[0013] Preferably, the two controllers are communicatively connected to achieve automatic switching. When the locomotive moves forward, the controller at the front end works. When the locomotive moves backward, the controller at the rear end works.
[0014] Preferably, the siren device includes an electric siren and a siren 3. The controller is only connected to the siren 3, so that there is an electrical interlock between the siren 3 and the headlight 2. Only one of the headlight 2 and the siren 3 can be enabled at the same time.
[0015] Preferably, the electric siren is provided with a separate control button.
[0016] As Figure 2 shown, the working principle of the utility model is as follows: Two sets of siren schemes are added to the locomotive. One set is an electric siren, that is, an electric horn, whose volume is relatively small and can be controlled within the range where it can sound at night. The other set is a siren 3, and the sound of the siren 3 is relatively loud and will disturb the residents at night. Two switches are respectively set in the controller to independently control the electric siren and the siren 3. At the same time, a circuit logic related to the activation of the headlight 2 is added, and this circuit logic is used to effectively control the electric siren and the siren 3. Specifically, when the locomotive operates at night and the headlight is turned on, due to the control of the circuit logic, the siren 3 will automatically be unable to be used, while the electric siren is always open and is not affected by this circuit, so it can be used normally. In this case, even if the driver or crew accidentally presses the button of the siren 3 at night, the siren 3 will not make a sound; thus, the purpose of not disturbing the residents at night is achieved.
[0017] After the control switch of the headlight 2 is turned on at night, the intermediate relay K6 operates, the normally closed contact is disconnected, and the power supply of the siren 3 is automatically cut off. After the headlight 2 is turned off, the normally closed contact closes, and the power supply of the siren 3 is automatically restored.
