Description

Control circuit for headlamp of railway passenger car

Technical Field

The utility model belongs to the technical field of railway passenger car control systems, and particularly relates to a headlamp control technology.

Background

The urban railway passenger car headlamp integrates a dipped headlight and a high beam, different illumination can be realized under different working conditions, and part of vehicles are also provided with marker lights. The dipped headlight and the high beam are switched according to the light control button and the direction handle of the driver controller, and the marker light is generally set to be normally on. The vehicle is in the tunnel or the vehicle section, and the staff can only judge the front end or the tail end of the vehicle according to the state of the vehicle headlamp at a position far away from the vehicle, can not judge whether the vehicle is in a forward, backward or standby state, and can only determine when the distance is close, thereby influencing the working efficiency and easily causing safety accidents.

Disclosure of Invention

The utility model aims at the problem that the state of a vehicle cannot be quickly judged by naked eyes when the urban railway passenger car is in a front tunnel or a vehicle section and the vehicle is far away, and provides a method for switching a marker lamp between different colors (red and white) and different states (normally bright and twinkling) under different states of the vehicle according to control logic on the premise of ensuring that the volume of a headlamp is not changed, and a worker in the tunnel or the vehicle section can quickly judge whether the vehicle is in a forward, backward or standby state at a distance.

In order to achieve the purpose, the utility model provides a control circuit of a head lamp of a railway passenger car, which is characterized in that: the left and right marker lamps are arranged at the vehicle end and are in the form of LED lamp beads and used for changing colors to judge working states, and the marker lamps are connected with a power supply through direction handles of driver controllers and keys of the driver controllers of two drivers to form 5 channel working modes, so that three working states of forward, backward and standby are realized.

The specific circuits of the 5 channels are as follows:

the vehicle advancing state: when the key of the head car is in an activated state, the direction handle is forward, the head car is closed through a fifth channel, namely the normally open contact of the key, the forward normally open contact of the direction handle is closed, the contact of the marker light is electrified, and the normally-on state of the white light is displayed; the tail car does not act through a third channel, namely the normally closed contact of the key, the forward normally open contact of the direction handle is closed, the contact of the marker light is electrified, and the normally-on state of the red light is displayed;

vehicle reverse state: when the key of the head car is in an activated state, the direction handle is backward, the head car is closed through the first channel, namely the normally open contact of the key, the backward normally open contact of the direction handle is closed, the contact of the marker light is electrified, and the normally-on state of the red light is displayed; the tail car does not act through a fourth channel, namely the normally closed contact of the key, the backward normally open contact of the direction handle is closed, the contact of the marker light is electrified, and the red light flashing state is displayed;

vehicle standby state: the key is not activated, the direction handle is in a zero position, the head car passes through the second channel, namely the normally closed contact of the direction handle, the contact of the marker light is electrified, the normally-on state of the red light is displayed, and the modes of the tail car and the head car are consistent.

Further, the rear marker light red flashing frequency was 2 times/second.

Furthermore, the direction handles of the drivers of the two drivers' cabs are linked through a train control line penetrating through the whole train.

The marker light arranged in the headlamp has two states of red and white, flashing and normally-on, three working states of forward, backward and standby are realized through the design of 5 channel working modes, and the state of the urban railway passenger car in the main tunnel or the vehicle section in the state of long vehicle distance is quickly judged through the switching of the marker light, so that the safety is improved.

Detailed Description

Referring to fig. 1-5, the specific embodiment of the utility model is that a left marker light 1, a right marker light 2 and a far and near light 3 are respectively arranged at the vehicle end part, a driver controller 4 is respectively arranged at the head and the tail of two driver rooms, the direction handles of the driver controller are divided into a forward F position, a backward R position and a zero position 0, and a key 5 switch (an ON position and an OFF position) is arranged, the direction handles of the two driver rooms can realize a linkage state 14 by penetrating through a train control line of a whole row, namely the action of the direction handle at any end is regarded as simultaneous action of the two ends, and the key switch can identify which vehicle the driver controls, so as to judge the activation end by the action of the key.

The control circuits at the head and tail ends of the train are completely consistent. Firstly, a DC 110V power supply is led out from a storage battery, and enters a marker lamp control circuit through a first channel 6 to a fifth channel 10, and the red lamp normally-on, the red lamp flickering and the white lamp normally-on of the marker lamp are respectively corresponding to the control circuit, and the specific description is as follows:

the vehicle advancing state: the head car key is in an activated state, and the direction handle of the driver controller is forward F. At this time, the head car is closed through a fifth channel 10, namely the normally open contact of the key 5, the forward normally open contact of the direction handle is closed, the contact of the marker lamp is electrified, and the normally-on state 11 of the white lamp is displayed. The tail car does not act through a third channel 8, namely the normally closed contact of the key, the forward normally open contact of the direction handle is closed, the contact of the marker light is electrified, and the normally-on state 13 of the red light is displayed.

Vehicle reverse state: the head car key is in an activated state, and the direction of the driver controller is towards the handle to the rear R.

At the moment, the first vehicle is closed through the first channel 6, namely the normally open contact of the key, the backward normally open contact of the direction handle is closed, the contact of the marker light is electrified, and the normally-on state 13 of the red light is displayed. The tail car does not act through a fourth channel 9, namely the normally closed contact of the key, the backward normally open contact of the direction handle is closed, the contact of the marker light is electrified, and the red light flickering state 12 is displayed. Vehicle standby state: the key is not activated, and the direction of the driver controller is zero 0 of the handle. At this time, the head car passes through the second channel 7, namely the normally closed contact of the direction handle, the contact of the marker light is electrified, and the normally-on state 13 of the red light is displayed. The tail car mode is consistent with the head car mode.
