Abstract
The invention relates to the technical field of train ventilation control, in particular to a dynamic control system for the air tightness of a dual-flow vehicle, comprising a positioning module, a control module, a controlled damper module and a timing module. The positioning module locates the real-time position of the vehicle, and the control module obtains Real-time position and according to the real-time position send the opening adjustment signal to all the controlled damper modules on the vehicle, and send the timing signal to the timing module to start the timing. Whether the actual opening reaches the preset opening, if not, the control module determines whether the actual opening is less than the preset opening, and when the actual opening is less than the preset opening, the control module sends a reciprocating adjustment signal to the controlled damper module. The present invention can automatically and dynamically adjust the air pressure in the vehicle compartment through the controlled air door module, thereby reducing the variation of the air pressure when the vehicle is running in two different environments.
