Gas path control method and gas path system capable of preventing door from being opened by mistake and vehicle door
The invention provides an air path control method and an air path system capable of preventing door opening by mistake and a vehicle door, at least two branch air paths connected in parallel are adopted to provide compressed air for a door opening and closing device, the branch air paths are controlled to only output and supply air in one direction towards the downstream door opening and closing device, and the air pressure required by the door opening and closing device in the door closing state is kept. An upstream main air supply path is changed into a multi-path air supply path from a single path in the prior art, air supply to the downstream can still be guaranteed when faults such as leakage and pull-off occur in a branch air path, the residual pressure when the air supply path breaks down is improved, the automobile door can still be kept in a closed and pressed safe state, and the safety of the automobile door is guaranteed. The hidden danger that the train door is in a free state and is opened by mistake due to pipeline leakage and pull-off is avoided, and train operation safety is effectively guaranteed.
本发明提供了一种可预防误开门的气路控制方法、气路系统及车门,采用至少两条并联的支气路向开关门装置提供压缩空气，控制所述支气路仅向下游开关门装置方向单向输出供风，保持关门状态时所述开关门装置所需的空气压力。本发明将上游的主供风气路由现有技术的单路改为多路供风，在有支气路出现泄漏和拉脱等故障时，依然可以保证向下游供风，提高供风气路发生故障时的剩余压力，仍能维持车门处于关闭及压紧的安全状态，避免因管路泄漏、拉脱造成车门处于自由状态而误开的隐患，有效保证列车运行安全。
