AI Technical Summary
Traditional tunnel pressure regulation systems cannot adapt to dynamically changing train speeds, resulting in energy waste and equipment damage, and have poor durability in complex environments.
The system employs flexible airbags and a generator system. By combining conical and teardrop-shaped flexible airbags with a flow guide pipe, air pump, laser sensor, and control center, dynamic pressure regulation and energy recovery are achieved. The laser sensor monitors train information in real time, the pressure sensor monitors tunnel pressure fluctuations, and the generator recovers energy and stores it in the battery.
It enables dynamic regulation of pressure within the tunnel, reduces transient pressure, improves tunnel safety and passenger comfort, and enhances energy efficiency.
