What is the difference between moving block and traditional automatic block?

Moving block refers to communication-based block mode, in which the running speed of the following vehicle is automatically set according to the distance from the preceding vehicle and the line conditions.

The train interval of this blocking system is not fixed. As long as the braking distance of the following train is ensured and the appropriate protection distance is added, the traffic density is greatly improved, which is especially suitable for high-density urban rail transit systems.

The principle of automatic block system is to transmit the track information to the on-board system of EMU through the rail, and predict the idle state of the two blocks in front of the train through the red, yellow and green display mode of the signal.

The red light indicates that there is someone in the partition, and the train is required to stop, and it is temporarily not allowed to cross (it can run at a low speed after 2 minutes); The yellow light indicates that there is isolation block ahead, and the train is required to pay attention to running; The green light indicates that there are at least two zones ahead, indicating that the train can run at the specified maximum speed.
