The invention discloses an automatic weighing metering
system for a granary. The
system comprises a weighbridge. Multiple
infrared light curtain detectors limit a vehicle
parking area. A host computer, a waiting area and a camera unit are arranged near the weighbridge. The host computer is configured in a way that after a grain carrier worker stays in the waiting area and the face information of the worker is verified, an RFID card is swiped, the weighbridge records weighing data and the camera unit captures current video frames at the same time after a grain carrying vehicle stays in the vehicle
parking area, the camera unit does not capture the face and the weighing data by the weighbridge is steady, and the data and the video frames are uploaded to the host computer; and if the grain carrying vehicle does not stay in the vehicle
parking area, or the camera unit captures the face or the weighing data by the weighbridge is not steady, the weighbridge does not have a weighing effect and will emit reminding sound. The invention also discloses an automatic weighing metering method for a granary. Man-made
cheating can be prevented in many ways, smooth
information operations of a whole course during which a grain carrying vehicle enters a granary and exits from the granary can be achieved, the number of workers can be reduced,
operating procedures can be standardized, and highly efficient and automatic weighing metering is achieved.
