The traditional sliding door drive system is mostly driven by electro-hydraulic force. In order to make the device more environmentally friendly and safe, combined with the relevant specifications of ship equipment, aiming at the opening and closing needs of passenger cabin wall and deck, a pneumatic drive system was developed. In the system, pneumatic transmission was used as the driving force of door body movement, which could effectively reduce the volume of equipment and avoid environmental pollution caused by oil leakage. Its main functions included automatic closing, remote release, door side release, remote shielding, collision protection, fire protection, energy storage emergency opening and closing, manual emergency opening and closing. After field debugging and verification, the designed system could achieve the above functions well.
