The display module 23 is connected to the power supply module 20 and the communication module 21. The communication module 21 is an RS485 communication module 21. The input voltage of the communication module 21 is 110V, and the output voltage of the communication module 21 is 24V;
[0027] Specifically, as Figure 1 and Figure 5 shown, it is connected to the housing 1 through a wire harness and the socket 15, and then connected to the BCU power supply system. On the other side, there is a synchronous interface connected to the power supply. When the power supply of the locomotive braking control unit BCU is abnormal, the voice module 22 will give a voice alarm, and the result of the abnormal power supply will be displayed on the display screen 3 through the display module 23, so that the staff can be notified in time of the abnormal power supply of the locomotive braking control unit BCU, reducing accidents caused by the abnormal power supply of the locomotive braking control unit BCU. It does not rely on the judgment of the crew, reduces manual participation, has higher accuracy, and is automatically detected throughout the process, reducing personnel operations.
[0028] Embodiment 2: At the upper and lower ends on both sides of the rear end of the housing 1, there are fixed blocks 9 fixedly connected. Between the fixed blocks 9, there is a connecting rod 11 fixedly connected. An articulated sleeve 12 is movably hinged on the outside of the connecting rod 11. At the bottom end of the articulated sleeve 12, there is a protective plate 13 fixedly connected. At the bottom end of the protective plate 13, there is a second magnetic block 14. At the top and middle of the rear end of the housing 1, there are first magnetic blocks 10. The protective plate 13 is arranged at the rear end of the socket 15.

There are two groups of the housing 1;
[0029] Specifically, as Figure 3 shown, the protective plate 13 can block the socket 15, preventing dust and impurities from entering the inside of the socket 15 when the socket 15 is not in use, thereby protecting the socket 15 and preventing dust and impurities from affecting the service life of the socket 15. When the socket 15 needs to be used, when the articulated sleeve 12 is rotated, the protective plate 13 rotates to the top of the connecting rod 11.

Ventilation holes 8 are formed in the inner side walls on both sides of the housing 1, and multiple groups of ventilation holes 8 are provided.
[0031] Specifically, as Figure 1 , Figure 2 and Figure 4 shown, when the heat dissipation fan 5 is started, the heat dissipation fan 5 blows air into the inside of the housing 1 to quickly dissipate heat and cool down the inside of the housing 1, preventing the components from being damaged due to excessive temperature inside the housing 1. The ventilation holes 8 can facilitate the ventilation inside the housing 1. The filter net 4 and the bamboo charcoal filter plate 16 can filter the incoming air, which can not only filter dust and impurities, but also adsorb moisture, thereby preventing dust and impurities from affecting the service life of the components and preventing moisture from affecting the components.
[0032] Working principle: When the utility model is in use, a locomotive usually has a locomotive A end and a locomotive B end. When the A end and the B end are normal, it is judged that the BCU power supply is normal and a normal instruction is output. The communication module 21 and the display module 23 display that the BCU power supply is normal. When the external power supply line of the BCU at the A end loses power, it is judged that the power supply of the BCU at the A end is abnormal and a fault instruction is output. The communication module 21 and the display module 23 display the abnormal power supply of the BCU at the A end on the display screen 3, and at the same time, the voice module 22 issues a voice alarm of "Attention, the BCU at the A end has lost power". When the external power supply line of the BCU at the B end loses power, similarly, the abnormal power supply of the BCU at the B end is displayed on the display screen 3, and at the same time, a voice alarm of "Attention, the BCU at the B end has lost power" is issued. The protection plate 13 can block the socket 15 to prevent dust and impurities from entering the inside of the socket 15 when the socket 15 is not in use, thereby protecting the socket 15 and preventing dust and impurities from affecting the service life of the socket 15. When the socket 15 needs to be used, when the hinge sleeve 12 is rotated, the protection plate 13 rotates to the top of the connecting rod 11. The first magnet 10 and the second magnet 14 cooperate with each other to limit the protection plate 13 to prevent the protection plate 13 from accidentally falling off. When the heat dissipation fan 5 is started, the heat dissipation fan 5 blows air into the inside of the housing 1 to quickly dissipate heat and cool down the inside of the housing 1, preventing the components from being damaged due to excessive temperature inside the housing 1. The ventilation holes 8 can facilitate the ventilation inside the housing 1. The filter net 4 and the bamboo charcoal filter plate 16 can filter the incoming air.
