The first pyroelectric infrared sensor 1, the second pyroelectric infrared sensor 2 and the third pyroelectric infrared sensor 3 are used for detecting whether a person is in the lower portion of a hopper 101 of the movable garbage compression box. In this embodiment, the first pyroelectric infrared sensor 1, the second pyroelectric infrared sensor 2 and the third pyroelectric infrared sensor 3 preferably adopt commercially available pyroelectric infrared sensors specially used for detecting human body infrared radiation, the pyroelectric infrared sensors specially used for detecting human body radiation are passive sensors, do not emit any radiation, are only sensitive to infrared radiation with a wavelength range of 7-10 um, are exactly matched with the wavelength of human body infrared radiation, and do not react to infrared rays with other wavelengths, so that the hopper can effectively eliminate the self-overturning of the moving hopper and the interference of other objects when in use, and misjudgment is effectively prevented. In this embodiment, the first pyroelectric infrared sensor 1, the second pyroelectric infrared sensor 2 and the third pyroelectric infrared sensor 3 are preferably human body infrared sensing pyroelectric infrared sensors of model No. RE200B-D203S of shenzhen shang xiang core micro-technology limited company.
