The invention relates to a train network control system, in particular to a motor train unit central control unit multithread processing method. A program is divided according to processes and threads to improve the executing efficiency and reliability of the program; the whole program is divided into two processes, namely a main CCU progress and an auxiliary CCU progress, the main CCU progress and the auxiliary CCU progress shares a memory to achieve data interaction, the phenomenon that the auxiliary CCU progress breaks down and accordingly program execution of the main CCU progress is influenced is avoided, and the thread executing reliability of a CCU is improved. An MVB information board card read-write thread and an MVB traction board card read-write thread which run synchronously are set in the main CCU progress, and a logic operation thread and a logic variable updating thread which run in a mutual exclusion mode are set, so that data reading seed and data operation real-timeliness of a central control unit are effectively improved.
