1. A logic intelligent control system of train door based on intelligent control units, comprising: a first intelligent control unit, a second intelligent control unit and a door controller,
wherein the first intelligent control unit is located in a selected vehicle of a train, the second intelligent control unit is located in each of remaining vehicles of the train, and the door controller is located in each vehicle of the train; the first intelligent control unit comprises a plurality of door control instruction output ports, and the first intelligent control unit and the second intelligent control unit are provided with a plurality of door control instruction input ports corresponding to the plurality of door control instruction output ports;
the first intelligent control unit is configured to output a corresponding door control instruction through a corresponding door control instruction output port after acquiring door control operation information; and
each door control instruction input port is configured to drive a corresponding door controller control port to control the door controller of a corresponding vehicle to execute the door control instruction after receiving a door control instruction;
wherein the first intelligent control unit and the second intelligent control unit are configured to be connected with a train braking control unit through a first speed signal acquisition port and a second speed signal acquisition port, respectively;
the first speed signal acquisition port is configured to have a signal when a train speed is equal to or less than a first preset speed, and have no signal when the train speed is greater than the first preset speed;
the second speed signal acquisition port is configured to have a signal when the train speed is equal to or less than a second preset speed, and have no signal when the train speed is greater than the second preset speed; and
the second preset speed is greater than the first preset speed.
