In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following further detailed description of the exemplary embodiments of the present application with reference to the accompanying drawings makes it clear that the described embodiments are only a part of the embodiments of the present application, and are not exhaustive of all embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

In the related art, due to the long control loop and the numerous components of the external lighting system, the external lighting system needs to continuously work all day long in the operation process of the railway vehicle, and in addition, due to the influence of actual application conditions such as electromagnetic compatibility, temperature and the like, the components in the control loop such as a lamp control relay are easy to break down. In addition, the number of components such as the lamp control relay is large, the cost of a single component is high, the cost of an external lighting system is high, and the subsequent maintenance cost is high.

In order to overcome the above problems, the present embodiment provides a control system, which uses a highly inherited lamp control module to control the states of a plurality of external headlight sets, so as to facilitate reducing the number of lamp control relays and DI/DO modules, facilitate reducing external lighting system faults caused by the faults of the lamp control relays, reduce the fault rate of the external lighting system, and facilitate reducing the procurement cost and the maintenance cost of a control loop of the external lighting system. Wherein, the English of DI is called Digital in, and Chinese is called Digital input; the English language of DO is called Digital out and the Chinese language is called Digital output.

As shown in fig. 1 to 2, the present embodiment provides a control system for controlling a group of exterior lighting lamps of a railway vehicle. The external lighting lamp set includes: a left headlight group 23, an upper headlight group 22, and a right headlight group 21. The left headlight group 23, the upper headlight group 22, and the right headlight group 21 may be collectively referred to as a headlight group for convenience of description.

The left headlight group 23, the upper headlight group 22, and the right headlight group 21 each include: light and signal lamp. The illuminating lamp mainly meets the illumination requirement of a driver for observing the state of a front road in the running process of a vehicle; the illuminating lamp can comprise a strong light lamp and a weak light lamp. The signal lights may be illuminated in white or red, for example, the signal lights may include a white signal light and a red signal light, the illuminated colors being used to identify the current status of the rail vehicle and to alert an outsider. For convenience of description, the illumination lamp and the signal lamp are collectively referred to as a lamp, that is, the lamp in this embodiment and the following embodiments is an illumination lamp and/or a signal lamp, and may be a lamp with other functions.

In this embodiment, the specific structure and implementation process of each headlamp group may adopt conventional settings in the art, and this embodiment is not limited specifically here. The head lamp group can adopt a structure of combining a light-emitting diode (LED) lamp and a xenon lamp.

The control system includes: knob switch 11, toggle switch 12, DI/DO module 13 and lamp control module 14.

The rotary switch 11 is disposed in the cab, and the specific position of the rotary switch 11 in the cab can be set according to actual needs, which is not specifically limited in this embodiment. The knob switch 11 can have three working positions, namely an automatic position, a white light position and a red light position. When the knob switch 11 is turned on to the white light position, the corresponding head lamp set is controlled to light the white light. When the knob switch 11 turns on the red light position, the corresponding head lamp set is controlled to light the red light. When the knob switch 11 is turned to the automatic position, the state of each headlamp group can be controlled by turning the switch 12. The person in the cab can drive the knob switch 11 to the corresponding working position according to the actual requirement. In addition, the specific structure of the rotary switch 11 may adopt a conventional configuration in the art, and the present embodiment is not limited in detail here.

The toggle switch 12 can be disposed in the cab, and the specific position of the toggle switch 12 in the cab can be set according to actual needs, and the embodiment is not limited in detail here. For example, the toggle switch 12 may be provided at a driver's console to facilitate operation by a train driver. The toggle switch 12 is used for being conducted with the rotary switch 11 when the rotary switch 11 is in the automatic position. After the toggle switch 12 is connected to the knob switch 11, the driver's cabin can adjust or select the status of the headlight set through the toggle switch 12. The toggle switch 12 corresponds to a high beam position, a low beam position and an off position.

Specifically, when the toggle switch 12 is located at the high beam position, it can be used to control the white signal lamps and the high beam lamps in each head lamp set to be turned on; at this time, the function realized by the external lighting system may be referred to as a high beam. When the toggle switch 12 is at the position of the high beam low beam light, it can be used to control the white light and the low beam light of the signal light in each head lamp set to light; at this time, the function realized by the external lighting system may be referred to as high beam dim. When the toggle switch 12 is at the dipped headlight position, it can be used to control the white lights of the signal lights in each headlight group to be turned on; at this time, the function performed by the exterior lighting system may be referred to as a low beam. When the toggle switch 12 is at the low beam and low light level, it can be used to control the signal lights in each head lamp set to light up; at this time, the function performed by the exterior lighting system may be referred to as low beam light. When the toggle switch 12 is in the off position, the control circuit can be used for controlling all the head lamp groups to be turned off; at this point, the function performed by the external lighting system may be referred to as all lights extinguished. Of course, the functions of the lamp position of the toggle switch 12 and the external lighting system are not limited thereto, and the embodiment is only illustrated here.

The DI/DO module 13 is electrically connected to the toggle switch 12 for receiving an output signal of the toggle switch 12. The DI/DO module 13 is electrically connected to the rotary switch 11 and is configured to be conducted with the rotary switch 11 when the rotary switch 11 is in the white light position or the red light position. The DI/DO module 13 is used for receiving output signals of the toggle switch 12 and the rotary switch 11. The DI/DO module 13 is also used to generate corresponding digital quantity codes according to the received output signals.

Illustratively, when the rotary switch 11 is in the red light position, the DI/DO module 13 encodes the digital quantity generated from the output signal when the rotary switch 11 is in the red light position as "0011". When the rotary switch 11 is in the white light position, the DI/DO module 13 encodes "0110" according to the digital quantity generated by the output signal when the rotary switch 11 is in the white light position.

When the rotary switch 11 is in the automatic position, the DI/DO module 13 needs to generate a digital code according to the output signal of the toggle switch 12. When the toggle switch 12 is in the off position, the DI/DO module 13 encodes "0000" as a digital quantity generated from the output signal when the toggle switch 12 is in the off position. When the toggle switch 12 is in the low beam dim light position, the digital value generated by the DI/DO module 13 according to the output signal when the toggle switch 12 is in the low beam dim light position is encoded as "0110". When the toggle switch 12 is in the low beam position, the digital value generated by the DI/DO module 13 from the output signal when the toggle switch 12 is in the low beam position is encoded as "1001". When the toggle switch 12 is at the high beam low beam light level, the DI/DO module 13 encodes the digital value generated according to the output signal when the toggle switch 12 is at the high beam low beam light level to "1100". When the toggle switch 12 is at the high beam position, the DI/DO module 13 encodes the digital quantity generated according to the output signal when the toggle switch 12 is at the high beam position into "1111".

Of course, the form of digital quantity coding is not limited thereto, and the embodiment is only exemplified here.

The lamp control module 14 is used for controlling the state of the headlamp group according to the digital quantity code sent by the DI/DO module 13.

And the lamp control module 14 receives the digital quantity code sent by the DI/DO module 13, and controls the signal lamps in each headlamp set to be turned on when recognizing that the digital quantity code sent by the DI/DO module 13 is '1001'. And the lamp control module 14 receives the digital quantity code sent by the DI/DO module 13, and controls the signal lamps in each headlamp set to be turned on when recognizing that the digital quantity code sent by the DI/DO module 13 is "0110". And the lamp control module 14 receives the digital quantity code sent by the DI/DO module 13, and controls all the head lamp groups to be turned off when recognizing that the digital quantity code sent by the DI/DO module 13 is "0000". And the lamp control module 14 receives the digital quantity code sent by the DI/DO module 13, and controls the red light of the signal lamp in each head lamp group to be turned on when recognizing that the digital quantity code sent by the DI/DO module 13 is '0011'.

In addition, as shown in fig. 3, the control system may further include a power module 15, and the power module 15 is electrically connected to the lamp control module 14 and is configured to supply power to the lamp control module 14. The power module 15 may be used to convert the power of the rail vehicle into power suitable for the lamp control module 14 and supply the power to the lamp control module 14. For example, the power module 15 may be used to convert a 110 volt power supply to a 24 volt power supply and supply the lamp control module 14. Of course, the power module 15 may be a separate battery module.

In addition, in the embodiment, the components (or modules) can be electrically connected through the control power line. The lamp control module 14 is provided with a lamp control module power supply switch 144, and the lamp control module power supply switch 144 is used for disconnecting or connecting the lamp control module 14 and the power supply module 15.

In one possible implementation manner, the lamp control module 14 further has a function of detecting a fault, and the lamp control module 14 can determine a specific line with the fault, so that an operator can quickly and accurately locate a fault point, and the efficiency of maintenance is improved. And when one line fails, other lines can work normally.

As shown in fig. 4 and 5, the lamp control module 14 has a first output terminal 141, a second output terminal 142 and a third output terminal 143, and the first output terminal 141, the second output terminal 142 and the third output terminal 143 are respectively used for being electrically connected to the right headlamp set 21, the upper headlamp set 22 and the left headlamp set 23. In this way, when at least one of the right headlight group 21, the upper headlight group 22, and the left headlight group 23 is out of order, the remaining headlight groups can operate normally. In addition, the right headlight group 21, the upper headlight group 22, and the left headlight group 23 are connected to the lamp control module 14 through independent lines, respectively, which facilitates the lamp control module 14 to detect a specific failed headlight group.

The lamp control module 14 is configured to generate control logic information according to the digital quantity code, and control the state of the corresponding headlamp group according to the control logic information. Illustratively, the digital quantity codes generated by the DI/DO module 13 for sending to the lamp control module 14 are as shown in table 1 below. Wherein, the functional train tail in table 1 corresponds to "0011" which indicates that the red light of the signal lamp is on.

TABLE 1 digital quantity code sent by DI/DO module to lamp control module

The lamp control module 14 is used for generating control logic information according to the digital quantity code, namely, a control code output to the head lamp group; the lamp control module 14 controls the output voltages of the first output terminal 141, the second output terminal 142 and the third output terminal 143 through the output control codes, thereby controlling the states of the corresponding headlamp sets. The control code may be as in table 2 below.

TABLE 2 control codes output by the lamp control modules

As shown in fig. 4 and 5, a1-a6 in table 2 is an output line of the lamp control module 14 corresponding to the left headlight set 23, and corresponds to the first output terminal 141; a7-a10 are output lines of the lamp control module 14 corresponding to the upper headlamp group 22 and corresponding to the second output end 142; a11-a15 are output lines of the lamp control module 14 corresponding to the right headlight group 21, and correspond to the third output terminal 143. In table 2, a "1" indicates that the lamp control module 14 controls the amount of power supplied to the lamp device through the corresponding line. In table 2, the parenthesis corresponding to a1-a15 are status information of the lamp when it is turned on.

The lamp control module 14 is further configured to obtain resistance values of the lines corresponding to the first output terminal 141, the second output terminal 142, and the third output terminal 143, respectively, determine that a corresponding head lamp group has a fault when the resistance values are not matched with corresponding control logic information, and generate a fault signal.

Illustratively, the lamp control module 14 is further configured to determine status information of the corresponding headlamp groups according to the acquired resistance values, match the status information with the corresponding control logic information, determine that the corresponding headlamp groups are failed when at least one of the status information is not matched with the control logic information, and generate a failure signal. For example, in the low beam dim state, the control code of the left headlight group 23 is "01000", and the state information of the respective light components in the left headlight group 23 is determined to be in the off state according to the detected resistance value, so that it is determined that the state information of the left headlight group 23 does not match the corresponding control code, and it is determined that the left headlight group 23 has a failure. When a certain lamp or line in the headlamp group has a disconnection fault, the corresponding resistance value at the corresponding output end is infinite.

The first output 141, the second output 142 and the third output 143 may respectively have a plurality of pins to connect to a plurality of circuits; at least one light element may be connected in each line. For example, each pin in each output terminal is connected to a lamp respectively, so as to reduce mutual interference among the lamp.

Further, the lamp control module 14 may be configured to detect resistance values of a plurality of lines corresponding to the first output terminal 141, the second output terminal 142, and the third output terminal 143, respectively, so as to determine a specific line and a lamp component with a fault. The resistance value may be detected by a conventional resistance measurement method, and this embodiment is not limited in this respect.

At this time, the lamp control module 14 may detect the resistance values of the lines corresponding to the first output terminal 141, the second output terminal 142, and the third output terminal 143; the lamp control module 14 determines the status information of each lamp in the corresponding headlamp group according to the detected resistance value, and then matches the determined status information with the corresponding control codes, respectively, if there is a mismatch between the status information and the corresponding control codes, it is determined that the lamp corresponding to the status information has a fault, and the faulty headlamp group is determined. For example, in the low beam dim state, the control code of the left headlight group 23 is "01000", and the state information of the respective lamp elements in the left headlight group 23 is determined to be in the off state according to the detected resistance value, it is determined that the state information of the left headlight group 23 does not match the corresponding control code, it is determined that the left headlight group 23 has a failure, and the signal lamps in the left headlight group 23 have a failure.

Of course, in other examples, since the resistance value of each lamp is a known value, the resistance value at the corresponding output end may be determined according to the control code, the determined resistance value may be matched with the detected resistance value, and if the determined resistance value is not matched with the detected resistance value, a fault may be determined.

Optionally, the lamp control module 14 is configured to detect the resistances of the first output terminal 141, the second output terminal 142, and the third output terminal 143 at preset intervals, so as to ensure that a fault of the lamp can be found in time. Illustratively, the lamp control module 14 is configured to detect the resistances of the first output terminal 141, the second output terminal 142, and the third output terminal 143 every 5 seconds or 10 seconds. Of course, the specific preset time period may be set according to actual situations, and this embodiment is not limited in particular here, for example, the preset time period may be 2 seconds, 3 seconds, 4 seconds, 5 seconds, 6 seconds, 7 seconds, 8 seconds, 9 seconds, or 10 seconds.

Optionally, the lamp control module 14 has a fourth output terminal, which is electrically connected to the DI/DO module 13; the DI/DO module 13 is used for electrically connecting with a cab display; the fourth output end is used for sending the fault signal to the DI/DO module 13, and the DI/DO module 13 sends the fault signal to the cab display, so that the cab display can correspondingly display according to the fault signal, and personnel in the cab can timely know and check the fault signal. The cab display is used for displaying the failed headlamp groups and/or lamp pieces according to the failure information.
