Example 3
The embodiment also provides a vehicle-mounted control system, which comprises the control device of the vehicle-mounted control system of the embodiment and a two-by-two-out-of-two safety platform consisting of a safety platform main system and a safety platform standby system.
The vehicle-mounted control system is a key actuating mechanism of the CBTC system, and the safety and the reliability of the vehicle-mounted control system are mainly a safety platform with a two-by-two-out-of-two redundancy architecture, so that better safety, reliability, usability and maintainability are provided for train operation.

When the main system cannot work normally, the standby system needs to smoothly take over the main system to work, and the process of double-set switching should be transparent for external equipment. The relation between the master and slave is updated in real time through a double-set state adjustment algorithm, so that the problem of seamless switching of the double sets is solved; meanwhile, in order to further ensure the smooth transition of the double sets, a double-coefficient data synchronization algorithm is formulated to prevent possible output jump in the switching process.
