Problems solved by technology

However, there is currently no effective verification method or measure for the fully automatic operation system at the beginning of R&D design and during operation and commissioning. To verify the function through field experiments will increase the R&D cost and prolong the R&D cycle to a certain extent, and it is difficult to adapt to the urban environment.

Description

technical field [0001] The present invention relates to the field of rail traffic control, more specifically, it relates to a fully automatic driving simulation training verification method, system, terminal and medium. Background technique [0002] In recent decades, the development of rail transit has roughly gone through three stages. One is the manual driving mode. The driver of the train drives the train in an independent signal system according to the operation diagram, and obtains the overspeed monitoring and protection of the ATP (Automatic Train Protection System); the other is the automatic operation mode of manual driving. Set up a driver, the main operation task is to open and close the doors for passengers to get on and off the train, and give the control signal for the train to start; while the acceleration, coasting, braking and stopping of the train are all communicated with the vehicle through the ATC (Automatic Train Control) signal system. The interface o...
