The wireless communication module 12 is for exchanging information with the column control ground device.

For example, the wireless communication module 12 receives the train control information, such as the driving permission sent by the wireless blocking center in the pilot ground device, through the GSM-R (GSM for Railway) wireless communication network, and transmits the received train control information to the The computer module 10 is securely controlled for generating a vehicle control command. The wireless communication module 12 also transmits the train position information and the operation mode information generated by the safety control computer module 10 according to the current running state of the train to the wireless blocking center through the GSM-R wireless communication network. In this way, the information exchange with the wireless blocking center is realized, so that the wireless blocking center can adjust the train control information sent to the train in real time according to the current running state of the train, thereby effectively ensuring driving safety.

In order to ensure the communication security of the wireless communication module 12 and the GSM-R wireless communication network, the wireless communication module 12 has a universal encryption device, and the universal encryption device has the same key as the wireless blocking center. Before the communication is performed, the security control computer module 10 generates a random number for the current communication according to the key, and is packaged into the first data packet together with the ID of the CTCS-3 level-controlled in-vehicle device, and is sent through the wireless communication module 12.
