Abstract

The embodiment of the invention provides a vehicle-mounted signal system and a vehicle-mounted signal communication method. The system comprises at least one processor, and an ATP software process andan ATO software process run in the same processor; the ATP software process is used for sending train state information to the ATO software process; and the ATO software process is used for calculating the train control information according to the train state information and sending the train control information to the ATP software process. According to the system and the method provided by theembodiment of the invention, the communication delay between the ATP software and the ATO software is reduced, the response time is shortened, and the parking precision of the train is improved.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a vehicle-mounted signal system and a vehicle-mounted signal communication method. Background technique [0002] With the widespread application of fully automatic driverless technology, multiple control systems with different functions are installed on train vehicles. For example, ATP (Automatic Train Protection, automatic train protection system) for preventing train collisions, and ATO (Automatic Train Operation, automatic train driving system) for safe automatic driving. [0003] The vehicle-mounted signaling system used in the prior art distributes ATP and ATO on different hardware modules, and uses network cables for communication based on the network protocol. The communication delay is relatively large, resulting in large error in speed measurement and distance measurement, and long system response time. Poor parking accuracy. Contents of the invention [0004] Embo...
