The passenger information system adopts a 1000M redundant ring network connection method. When any network cable is disconnected, it can still guarantee a 100M bandwidth trunk network. The transmission delay is less than 3ms; the station information and transfer information of the current line are provided to passengers in the form of multimedia playback; in case of emergency, passengers can notify subway staff through the alarm device for processing; real-time monitoring of train carriages and saving of surveillance videos; support flexible time period advertising business, such as weekly, monthly, annual, etc., and provide information services to passengers in the train through display terminals and broadcasting systems.

[0003] Based on the above, the inventors have discovered the following problems: most of the current onboard chassis of train passenger information systems store the passenger compartment control host inside the chassis, and connect the passenger compartment control host to the driver's room control host network, but the existing chassis lacks a protective mechanism. When hit by external force, it is easy to cause damage to the passenger compartment control host device inside the chassis, thereby affecting the normal operation of the passenger compartment control host device inside the chassis.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a train passenger information system on-board chassis is provided to achieve the purpose of having more practical value. Utility Model Content

A pair of slide bars 1012 are installed on the back of the box body 1001, and a mounting seat 1013 is slidably connected between the pair of slide bars 1012. A box door 1014 is installed on the front of the box body 1001 by bolts, and the fan 1004 is installed inside the heat sink 1003 by a "cross" bracket, and is near A cooling pipe 1005 is arranged at the bottom of the fan 1004. When the fan 1004 is working, air is sent into the heat sink 1003. The air passes through the cooling pipe 1005. Since the cooling pipe 1005 is filled with coolant, the air becomes cool. By installing a water inlet pipe 1006 and a water outlet pipe 1007 at both ends of the cooling pipe 1005, and respectively sleeved with a water inlet valve 1008 and a water outlet valve 1009 on the outside of the water inlet pipe 1006 and the water outlet pipe 1007, when the water outlet valve 1009 is opened, the coolant in the cooling pipe 1005 can be discharged from the water outlet pipe 1007. 07, and then open the water inlet valve 1008 to facilitate the injection of coolant into the cooling pipe 1005. By setting the pipeline 1010, since the pipeline 1010 is connected with the heat sink 1003, the cooling air inside the heat sink 1003 can flow into the pipeline 1010 and enter the box body 1001 through the air hole 1011, so as to dissipate heat for the components installed in the box body 1001.

When it is necessary to dissipate heat for the components and equipment inside the box body 1001, the fan 1004 is started to send air into the internal air of the heat dissipation box 1003 and pass through the cooling pipe 1005, so that the air becomes cold. The box 1003 is connected, so that the cooling air inside the heat dissipation box 1003 flows into the pipe 1010 and enters the box body 1001 through the air hole 1011, so as to dissipate heat for the components installed inside the box body 1001. By setting the water inlet valve 1008 and the water outlet valve 1009, when the water outlet valve 1009 is opened, the coolant inside the cooling pipe 1005 can flow out from the water outlet pipe 1007, and then the water inlet valve 1008 is opened to inject the coolant into the cooling pipe 1005. By setting the filter, dust and debris can be prevented from entering the heat dissipation box 1003 and the box body 1001.
