Abstract: A railway control signal transmitting method in an open transmission system is provided to obtain the security of a message against an error or fault by using an exclusive wired line. In a transmitter application layer of an open transmission system transmitting and receiving a railway control signal, an identifier field and a reception identifier field are generated in a sub frame to be transmitted(S211). In the transmitter application layer, a data sequence number field is generated in the sub frame(S221). The time stamp field is generated(S231). In the transmitter application layer, the reference transmission frame inserting the sub frame is encrypted(S261) and is transmitted to the TCP/IP layer(S271). The encrypted sub frame inserted into the basic transmission frame is decrypted in the application layer of the receiver(S291). If the decryption result of the sub frame is normal, the complementary code is checked in the application layer of the receiver(S301). The time stamp field, the data sequence number field, the identifier field, and the reception identifier field are confirmed and determined(S331).

Abstract: PURPOSE: A method for transmitting a train control signal in a closed transmission system is provided to transmit and receive a message in the closed transmission system by adding a time stamping field, a cyclic redundancy check field, and an identifier field to a basic transmission frame. CONSTITUTION: A source identifier field is generated in a transmitter application layer(S311). The source identifier field shows the data transmitter information of the basic transmission frame. The time stamping field is generated in the transmitter application layer(S321). The time stamping field represents the time information of the basic transmission frame. A cyclic redundancy check field is generated in the transmitter application layer using a cyclic binary code(S331). The completed basic transmission frame is transmitted to the receiver(S341). The cyclic redundancy check filed of the basic transmission frame is checked and verified in the receiver application layer. The time stamping field and the source identifier field of the basic transmission frame are checked in the receiver application layer(S361,S371).
