Description

technical field

[0001] The invention belongs to the technical field of communication, and in particular relates to a relay routing selection method for a dual dispatching command center. Background technique

[0002] With the development of economy and technology, rail transit (passenger train, subway, light rail) has become an indispensable means of transportation in people's daily life, and the traffic dispatching command communication system is an effective means to ensure the safe and punctual operation of passenger cars.

[0003] Figure 1 is a schematic diagram of the connection of the traditional single dispatching command center system. The dispatching command communication system has only one dispatching command center, and the dispatching communication is carried out between the center and the sub-stations under its jurisdiction through a ring relay route. When the center calls the substations, it can be made clockwise or counterclockwise, and vice versa.
