Method and device for detecting seeding quality of duckbill drum type seeding machine

Abstract

The invention discloses a method and device for detecting seeding quality of a duckbill drum type seeding machine, and the detecting method comprises the following steps that an off-line method is used to establish a seed vector signal characteristic vector library; during normal operation of the seeding machine, the signal conditioning circuit collects capacitance information of the detecting capacitance sensor and the reference capacitance sensor when the seed passes through the detection field of the detecting capacitance sensor and performs differential operation to obtain differential capacitance information, and the wireless transmission module transmits the differential capacitance information to the vehicle-mounted terminal; the vehicle-mounted terminal extracts the peak value, pulse width and peak area of the signal by using a frequency domain algorithm according to the differential capacitance information, matches with the seed response signal characteristic vector library, and combines the seed variety, bulk density and water content information to determine whether the seed is a single particle or double particles; and if double particles, the vehicle terminal prompts an alarm and records the positioning information corresponding to the double particles. The invention also provides a detecting device for implementing the above detecting method.

Description

technical field [0001] The invention relates to an online detection technology of a seeder, in particular to a method and a device for detecting the seeding quality of a duckbill drum type seeder. Background technique [0002] Precision seeding technology has become an important feature of modern agricultural production, and it is also one of the important technologies for increasing agricultural production and harvest and reducing food production costs. In order to increase cotton production, precision film-covered seeding technology is widely used in Xinjiang cotton area. In response to this agronomic requirement, duckbill roller-type precision film-laying seeders are widely used in cotton fields in Xinjiang to achieve perforation and sowing on film in cotton fields. As the core component of the seeder, the precision seed metering device has a direct impact on the quality of the sowing operation. Due to their different adaptability, mechanical and air-suction precision m...
