When controlling the left turn light 111, the first pin 1011 of the input 101 may include pin 2 (i.e., IN0 IN table 1, denoted as left turn input 1 IN fig. 4), pin 3 (i.e., IN1 IN table 1, denoted as left turn input 2 IN fig. 4), pin 9 (i.e., IN7 IN table 1, denoted as open left door IN fig. 4), and pin 11 (i.e., IN9 IN table 1, denoted as close left door IN fig. 4) of the X1 terminal.
The first pin 1021 of the output terminal 102 includes pin 1 (i.e., KB0 in Table 3, denoted as left turn output 1 in FIG. 4), pin 2 (i.e., KB1 in Table 3, denoted as left turn output 2 in FIG. 4) on the X3 terminal.
Specifically, the process of controlling the operation of the left turn lamp 111 is as follows:
when the rail vehicle requires a left turn, the operator presses the left turn button S01 and the current reaches the interface IN0 and/or IN1 of the input 101 IN the first pin 1011, where the interfaces IN0 and IN1 are of redundant design, so that the input 101 detects a high signal, i.e. an indication signal, at the interface IN0 and/or IN1 IN the first pin 1011, from which it is determined that the rail vehicle is about to turn left. The controller 10 then processes the indication signal to generate a control signal, and outputs the control signal through the interfaces KB0 and/or KB1 in the first pin 1021 of the output terminal 102, where the interfaces KB0 and KB1 are redundant in design, so as to control the left turn light 111 to blink, and control the blinking frequency of the left turn light 111 by using the PLC, which may be 1 Hz.
When the rail vehicle needs to open or close the left door, the operator turns on the left door opening relay contact K01 or turns on the left door closing relay contact K03, and the current reaches the interface IN7 or the interface IN9 of the input terminal 101 IN the first pin 1011, so that the interface IN7 or the interface IN9 of the input terminal 101 IN the first pin 1011 detects a pulse signal, i.e., an indication signal, and the rail vehicle determines that the rail vehicle is going to open or close the left door through the indication signal. The controller 10 then processes the indication signal to generate a control signal and outputs the control signal through the interfaces KB0 and/or KB1 in the first pin 1021 of the output terminal 102, where the interfaces KB0 and KB1 are redundant in design, thereby controlling the left turn light 111 to blink and controlling the blinking frequency of the left turn light 111, which may be 1Hz, using the PLC.

Specifically, the process of controlling the right turn light 112 is as follows:
when the rail vehicle requires a right turn, the operator presses the right turn button S02 and the current reaches the interface IN2 and/or IN3 of the input 101 IN the second pin 1012, where the interfaces IN2 and IN3 are of redundant design, so that the input 101 detects a high signal, i.e. an indication signal, at the interface IN2 and/or IN3 IN the second pin 1012, by means of which it is determined that the rail vehicle is about to turn to the right. The controller 10 then processes the indicator signal to generate a control signal and outputs the control signal via the interfaces KB2 and/or KB3 in the second pin 1022 of the output terminal 102, where the interfaces KB2 and KB3 are redundant in design, to control the right turn light 112 to blink and to control the blinking frequency of the right turn light 112, which may be 1Hz, using the PLC.
When the rail vehicle needs to open or close the right door, the operator makes the right door opening relay contact K02 turned on or the right door closing relay contact K04 turned on, and the current reaches the interface IN8 and/or IN10 of the input terminal 101 IN the second pin 1012, so that the interface IN8 and/or IN10 of the input terminal 101 IN the second pin 1012 detects a pulse signal, i.e., an indication signal, and determines that the rail vehicle will either open or close the right door through the indication signal. The controller 10 then processes the indicator signal to generate a control signal and outputs the control signal via the interfaces KB2 and/or KB3 in the second pin 1022 of the output terminal 102, where the interfaces KB2 and KB3 are of redundant design, to control the right turn light 112 to blink and to control the blinking frequency of the right turn light 112, which may be 1Hz, using the PLC.

The controller 10 then processes the indication signal to generate a control signal, and outputs the control signal through the interface KB7 of the sixth pin 1026 of the output terminal 102, so as to control the parking lamp 115 to flash, and control the flash frequency of the left turn lamp 111 by using the PLC, wherein the flash frequency may be 1 Hz. When the signal indicating a rail vehicle fault disappears, vehicle parking light 115 is extinguished.
When controlling the parking light 115, the third case is: when the operator presses the trouble button S04 and the parking button S05 simultaneously, the current reaches the interface IN6 IN the fifth pin 1015 and the interface IN5 IN the sixth pin 1016 simultaneously to the input terminal 101, so that the interface IN6 IN the fifth pin and the interface IN5 IN the sixth pin of the input terminal 101 simultaneously detect a high level, and at this time, the high level detected on the sixth pin 1016 is taken as an indication signal. The controller 10 then processes the indication signal to generate a control signal, and outputs the control signal through the interface KB7 of the sixth pin 1026 of the output terminal 102, so as to control the parking lamp 115 to flash, and control the flash frequency of the left turn lamp 111 by using the PLC, wherein the flash frequency may be 1 Hz. When both the signal indicating a rail vehicle fault and the park signal are absent, the vehicle parking light 115 is turned off.
