The invention relates to the technical field of ship design and construction, and discloses a positive pressure protection method and a positive pressure protection system. The positive pressure protection method is used for changing an extended explosion-proof area which can be communicated with an explosion-proof area on a ship into a closed safety area, the safety area is positive pressure, andthe explosion-proof area is negative pressure. The expansion explosion-proof area is provided with a plurality of communication structures capable of destroying the sealing performance. And the acquisition assembly detects whether the communication structure destroys the sealing performance of the extended explosion-proof area or not. And if the communication structure destroys the sealing performance of the extended explosion-proof area, the acquisition assembly sends a failure signal to the processing unit, the processing unit receives the failure signal and sends an alarm signal to the sound-light alarm unit, and the sound-light alarm unit receives the alarm signal and sends a sound alarm and a light alarm. The stress or pressure difference between the measurement explosion-proof areaand the expansion explosion-proof area is converted into whether the sealing performance of the expansion explosion-proof area is damaged or not, a high-precision pressure sensor does not need to be used or installed, so the cost is reduced.

    本发明涉及船舶设计及建造技术领域,公开了一种正压保护方法及正压保护系统。该正压保护方法用于将船舶上能够与防爆区连通的扩展防爆区变为封闭的安全区,安全区为正压,防爆区为负压。扩展防爆区具有多个能够破坏其封闭性的连通结构。采集组件检测连通结构是否已破坏扩展防爆区的封闭性。若连通结构已破坏扩展防爆区的封闭性,采集组件向处理单元发送失效信号,处理单元接收到失效信号并向声光报警单元发送报警信号,声光报警单元接收报警信号,并发出声警报和光警报。将测量防爆区与扩展防爆区的应力或压差转换为测量扩展防爆区的封闭性是否被破坏,无需使用和安装高精度的压力传感器,降低了成本。
