The invention provides a vehicle-mounted ATP
system compatible with C2ATO and CBTC. The
system comprises an application input layer, an application functional layer, an application output layer and amain calling module, wherein the application functional layer comprises all functional modules of the vehicle-mounted ATP
system of C2ATO and CBTC
train operation control systems; the application input / output
layers are compatible with all internal and
peripheral interfaces of the two
train operation control systems; the main calling module is used for acquiring
data information from the outside through each interface of the application input layer in the preset cyclic operation process, transmitting to each
functional module corresponding to the application functional layer, and sequentiallycalling each
functional module, so that the main calling module can actuate the
processing function under the current system according to the received
data information and transmitting the processed output information to the application output layer; and the output information is transmitted to the outside through each interface of the application output layer. According to the vehicle-mounted ATPsystem, seamless switching of two systems can be realized in the vehicle-mounted system controlled
train operating process, the transportation efficiency is ensured, and a train can run efficiently.
