And a vehicle-mounted Passenger Information System (PIS) 10 for acquiring the vehicle state data.
In one implementation of the present embodiment, the vehicle-mounted sensor 60 is as follows: the camera, the thermometer, the laser vibration meter, the microphone or the microphone are connected to the vehicle-mounted passenger information system 10 through a video transmission line, an audio transmission line and other equipment connection lines, and the vehicle-mounted passenger information system 10 acquires the whole vehicle state data of the train 100 through the plurality of vehicle-mounted sensors 30.
And the vehicle-mounted data terminal 20 is used for acquiring the whole train message data of the train.

comparing the whole train message data with pre-stored standard whole train message data to obtain a second working state of train parts;
if the message data of a certain part in the message data of the whole vehicle is larger or smaller than the message data of the prestored standard part, the part is indicated to be abnormal, the second working state of the part is abnormal, and the degree or the abnormal type is judged according to the size or the message value of the message data.
The current working state at least comprises: normal, abnormal sound, aging, crack, fracture, oil leakage, deformation, damage, corrosion, normal tire pressure, excessive tire pressure, insufficient tire pressure, serious tire pressure and failure of the vehicle door of the parts.
Further, if the first working state and the second working state of the same part are abnormal, the part is judged to be seriously abnormal, and a spare part is started or stopped for replacement immediately. For example: the first working state of the part tyre is that the surface of the tyre has cracks and is aged; and if the second working state of the component tire is that the tire pressure is seriously excessive, judging that the tire is serious, immediately stopping the tire, starting a spare tire or immediately stopping the vehicle to replace the tire.
And if the first working state of the same part is abnormal and the second working state is normal, replacing or maintaining the part after the train stops running. For example, the first operating state of the vehicle door is abnormal sound; and if the second working state of the vehicle door is normal, the vehicle door can be maintained when the train arrives at the station or stops running.
If the first working state of the same part is normal and the second working state is abnormal, the part can be maintained in a remote restarting or automatic restarting mode. For example, if the first operating state of the vehicle door is normal and the second operating state of the vehicle door is an obstacle in closing of the vehicle door, the vehicle door can be maintained by remote restarting or automatic restarting of the vehicle door controller.
In the application, the general whole vehicle state data represents the mechanical performance or appearance condition of parts on the train; the whole vehicle message data represents the electrical performance or the internal state of the parts on the train, and the whole vehicle message data and the train message data are combined together, so that the mechanical performance or the appearance condition of the train parts is detected in real time, the electrical performance or the internal state of the train parts is detected in real time, the integrity and the accuracy of detection can be improved, and the detection precision is further improved.
