The invention discloses an underwater self-adaptive pressure reduction method based on air diving, and belongs to the technical field of air diving pressure reduction, diving pressure reduction is divided into three modes including safe staying, deep staying and pressure reduction staying, the safe staying and the deep staying refer to that diving of a diver does not reach the pressure reduction-free time, and at the moment, the pressure reduction-free time is not reached by taking the water depth of 10 m as the boundary; when the depth of the diver is smaller than 20 m, the diver enters a safe staying mode, the diver stays at the water depth of 3-6 m for 3-5 min and then comes out of water, and if the water depth is larger than 20 m, the diver enters a deep staying mode. According to the underwater self-adaptive pressure reduction method based on air diving, the diving depth and the diving time of the diver are used for calculating the pressure reduction scheme in real time, the defect that the diving pressure reduction scheme is formulated in advance can be overcome, the diver is more flexible underwater, in addition, within the pressure reduction-free time, the pressure reduction algorithm can carry out safe staying and deep staying according to the diving depth, and the safety of the diver is improved. And the underwater diving safety of the diver is further ensured.

    本发明公开了一种基于空气潜水的水下自适应减压方法,属于空气潜水减压技术领域,潜水减压共分为三种模式,一是安全停留,二是深度停留,三是减压停留,安全停留和深度停留是指潜水员潜水未到达免减压时间,此时以10m水深为界,当潜水员深度小于20m时,潜水员进入安全停留模式,在水深3m~6m处停留3min~5min后出水,如果水深大于20m时,潜水员进入深度停留模式。该基于空气潜水的水下自适应减压方法,利用潜水员潜水深度和潜水时间实时计算减压方案,能够摆脱提前制定潜水减压方案的弊端,让潜水员在水下更加灵活,另外,在免减压时间内,减压算法能够根据潜水深度进行安全停留和深度停留,进一步确保了潜水员水下潜水安全。
