Kind Code:
A1
Abstract:
A sowing data processing method and apparatus, a particulate material sowing detection method, a flow control method of a sowing device (100), a sowing uniformity determining method and apparatus, a computer-readable storage medium, a sowing device (100) control apparatus, the sowing device (100) and an operation device (200), which relate to the field of control detection. The sowing data processing method is used for the sowing device (100). The sowing device (100) comprises a sowing unit (110) and a radar sensor (120), wherein the radar sensor (120) is arranged around a sowing outlet of the sowing unit (110). The method comprises: controlling the radar sensor (120) to detect spatial position data of a particulate material sprayed out of the sowing outlet; and according to the spatial position data, determining sowing flow data of the sowing unit (110). The sowing device (100) can accurately detect the spatial position data of the particulate material by means of the radar sensor (120), and the radar sensor (120) is not afraid of dust shielding; thus, the flow data of the sowed particulate material can be accurately and stably measured.
