Answer 1

对于我开发的这个问题，您可以使用findpeaks库。它被设计用于检测不同类型数据中的波峰和波谷。我试图在您的数据上测试它，但在这些值之间，还有许多其他字符串，如Pm:0、Hs:1、gain1、cld:0。我不知道该怎么办。但是有足够的文档可以帮助你自己完成。

小示例：

pip install findpeaks
x = [7193,7539,14310,14364,7414,7353,...,7231,7108]
fp = findpeaks(method="peakdetect")
results = fp.fit(x)
# All peaks and valleys can be found here:
results['df']
# Plot the results
fp.plot()
