The invention provides a salt-cavern gas storage cavity construction oil-water interface monitoring tool which comprises a detection device, a density adjusting device, a floating device and a timing device. The detection device is used for detecting underground pressure; the density adjusting device is connected with the detection device and is used for adjusting the initial density of the detection device to be consistent with the density at the oil-water interface; the timing device is connected with the floating device and is used for controlling the floating device to start at fixed time; and the floating device is connected with the detection device and is used for increasing the buoyancy of the floating device so as to drive the detection device to float. According to the salt cavern gas storage cavity-building oil-water interface monitoring tool, the cost input of downhole operation or optical fiber tripping-in can be reduced, high economic benefits are achieved, and large-scale application can be achieved.

This invention provides a radar-based sleep staging method, terminal, and storage medium. The method includes: acquiring human echo signals detected by radar over a preset monitoring area in real time, and calculating a sleep staging index corresponding to each calculation cycle during the sleep period based on the human echo signals; calculating a sleep staging threshold corresponding to the current calculation cycle based on the standard deviation of the sleep staging indices corresponding to multiple calculation cycles near the current calculation cycle; and determining the sleep staging result for the current calculation cycle based on the sleep staging index and the corresponding sleep staging threshold. This method can adaptively set the sleep staging threshold based on the user's own sleep patterns, thereby improving the accuracy of sleep staging calculations.
