Security inspection system and method for stones in rice seedlings

Abstract

The invention provides a security inspection system and method for stones in rice seedlings, the security inspection system comprises a drive shaft, a servo motor, a conveyor belt, an inlet light shield, a display screen, a cross beam, an X-ray security inspection machine, a support frame, an X-ray detection plate, an X-ray generator, a warning light, a computer, an exit light shield, a belt pulley, a speed reducer, a gear pair, a support seat, a coupling, a driven shaft, rice seedlings and a seedling taking table. Rice seedling images obtained by the X-ray security inspection machine can be filtered and divided by the computer, according to feature extraction and analysis of the obtained images, the stones in rice seedlings can be early detected and alarmed before the seedlings are loadedto a seedling transplanter, the seedlings, loaded to a seedling transplanter, being free of the stones can be ensured, the probability of seedlings being lost, damage of a planting mechanism and timefor stopping to removing the stones due to the mixed stones in the rice seedlings can be reduced, and the working efficiency and work quality of the seedling transplanter can be significantly improved.

Description

technical field [0001] The invention relates to a security inspection system and method for pebbles in seedlings, belonging to the field of intelligent agricultural machinery. Background technique [0002] my country's rice transplanter adopts blanket-like seedlings with soil. Due to the non-standard seedling raising process, rice growers bring the stones in the soil to the seedling tray when raising seedlings. If the transplanting mechanism of the rice transplanter grabs the seedlings with stones , The stone is stuck in the planting mechanism, so that the clutch of the planting mechanism is disengaged. If it cannot be found in time, it will cause the missing insertion of the corresponding rows of rice seedlings or the damage of the planting mechanism. If the missing insertion line is just in the middle of the working width method of the rice transplanter, the rice transplanter cannot be used to replenish seedlings, otherwise it will cause pressure damage to the transplanted ...

The control unit includes PLC controller, luggage detection device, frequency converter and motor. The PLC controller is connected to 5 sets of infrared tubes and alarms. When the luggage is taken away by the thief, the infrared tube sends a signal to the PLC controller, and then sends out an alarm signal. , to remind passengers or station staff, but this invention cannot be used for the monitoring of rice seedlings and stones

The patent (application number: 201610748757.8) discloses a device and method for rapid and automatic detection and alarm of dangerous goods in X-ray security inspection luggage, including an X-ray security inspection machine, a signal input interface, a digital signal processing unit, an alarm unit, and a signal output interface. Process the bag image captured by the X-ray security inspection machine, automatically identify guns and liquids in the bag, and send an alarm for suspicious dangerous goods, but the invention cannot be used to monitor stones in rice seedlings
