Moving block train operation control method and system based on train autonomous positioning

A system comprising:

• a train-mounted device located on a train;
• an all-IP multi-mode communication network configured to perform communication connection between the train-mounted device and a ground device;
• a railside device;
• and
• a center device,
• wherein the train-mounted device, the railside device, and the center device are configured to communicate with each other via the all-IP multi-mode communication network,
• wherein the system is configured to perform moving block train operation control steps including:
• the train-mounted device autonomously positioning a train and performing train integrity checking via satellites;
• determining a real-time position, speed, and line state of a preceding train via a train-to-train communication;
• and
• dynamically determining a movement authority and a target distance based on the real-time position, speed, and line state of the preceding train according to a train safety protection mechanism,
• wherein a control process of the moving block includes:
• step (1):
• determining a position of the train on a line, wherein the position comprises a train maximum safety head and a train minimum safety tail;
• step (2):
• obtaining, by the train-mounted device, an IP of the preceding train via a center resource management system;
• step (3):
• establishing, by the train-mounted device, wireless communication with the preceding train, and obtaining a position and a speed of the preceding train in real time;
• step (4):
• obtaining, by the train-mounted device, an available length of track resource and a point position ahead from the center resource management system;
• step (5):
• determining, by the train-mounted device, the movement authority;
• and
• step (6):
• dynamically monitoring, by the train-mounted device, train operation in real time according to the movement authority, a maximum restricted speed profile, and baking performance of a train, and controlling the train with moving block tracking operation of a train control system.
