Description

Train light control device

technical field

The utility model relates to a train lamp control device.

Background technique

In the prior art, the lights of railway locomotives and EMUs need to be manually controlled. During the operation of locomotives and EMUs, they often encounter mountainous areas, tunnels or areas with dark light. Control lights on and off. If the lights are turned on for a long time, it is not conducive to saving electric energy.

Contents of the invention

The purpose of the utility model is to provide a train light control device, which can overcome the deficiencies of the prior art, realize automatic control of train lights, reduce the workload of drivers, and improve the comfort of train passengers.

The purpose of this utility model is achieved in that:

A train light control device, which includes a light, a micro-control unit, a power supply, a light sensor and a plurality of drive modules, the light sensor is arranged on the top of the train and/or in the passenger compartment, the light sensor and the The power supply is connected with the micro-control unit, and the lamp is connected with the micro-control unit and the driving module.

Through the photoelectric sensor, the change of ambient light is converted into an electrical signal, and the micro-control unit judges and controls the driving module according to the magnitude of the current signal, thereby controlling the on-off of the train headlight circuit or the interior lighting circuit of the passenger compartment, to achieve The automatic compensation effect is provided when the light is insufficient, so that the driver can adapt to the ambient brightness faster when the light changes suddenly, so that passengers can feel more comfortable cabin lighting, making the train more humanized, safe, intelligent, and environmentally friendly.

In one of the embodiments, it also includes a mode selection switch, and the mode selection switch is connected with the micro control unit.

In one of the embodiments, the mode selection switch is a multi-level control switch or a stepless control switch.

Compared with the prior art, the train light control device of the utility model has the following beneficial effects:

The utility model applies light sensing technology to train lighting, so that the train lights can automatically adjust the brightness and darkness of the lights according to the intensity of the light, reduce the driver's operating intensity, and improve the comfort of the passengers.

Detailed ways

As shown in Figure 1, the utility model train lamp control device includes two lamps 11, a micro control unit 12, a power supply 13, a light sensor 14, a mode selection switch 15 and two drive modules 16. The light sensor 14 is arranged on the top of the train and/or in the passenger compartment, the light sensor 14, the power supply 13 and the mode selection switch 15 are all connected to the micro control unit 12, the lights 11 and the driving module 16 are all connected to the micro control unit 12, and each lamp 11 is correspondingly connected to a driving module 16.

Through the photoelectric sensor 14, the change of ambient light is converted into an electrical signal, and the micro-control unit 12 judges and controls the driving module 16 according to the magnitude of the current signal, thereby controlling the on-off of the train headlight circuit or the interior lighting circuit of the passenger room. It can automatically compensate when the light is insufficient, so that the driver can adapt to the ambient brightness faster when the light changes suddenly, so that passengers can feel more comfortable lighting in the passenger compartment, making the train more humanized, safe, intelligent, and environmentally friendly. .

Wherein, the mode selection switch 15 is a multi-level control switch or a stepless control switch, wherein the multi-level control switch 15 refers to that the train passenger compartment lights or headlights only have three states of bright, medium and dark to switch, and the stepless control switch It means that with the slight change of the input signal, the brightness of the train cabin lights or headlights is also adjusted accordingly, so as to realize the precise control of the light brightness.

Described power supply 13 adopts 12V DC power supply to supply power to control circuit, and DC power supply can be obtained from dry cell or driver's cab.

The micro-processing unit 12 adopts an enhanced single-chip microcomputer, has a high-precision internal AD function, can sense small changes in light intensity, and has two PWM (pulse wave modulation) outputs, which can realize the adjustment of headlights and passenger compartments respectively. The adjustment of the brightness of the lamp can realize the precise control under the step control and stepless control mode.

The driving module 16 can be selected according to the lamp power of different models, and generally uses a power triode 8550 (3A) or a MOSFET tube (such as IFR540, 33A) to meet the needs of various models.

The above-mentioned embodiments only express several implementations of the utility model, and the description thereof is relatively specific and detailed, but it should not be construed as limiting the patent scope of the utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the scope of protection of the utility model patent should be based on the appended claims.
