气吸式花生穴播器播种监测系统设计与试验
Design and experiment of seeding monitoring system of air-suction dibbler peanut for planter
摘要
Abstract
To address the issue of low seeding rate and unstable sowing quality on the peanut film during preci-sion seeding,a planting monitoring system of air-suction peanut burrow planter was designed based on infrared opti-cal fiber sensor.STM32F407VGT6 single chip microcomputer and encoder were used to collect speed pulse signals and seeding time interval information.Real-time monitoring of seeding quality information such as single seed seed-ing rate,missing seeding rate and reseeding rate was realized.Results showed that when the sensor installation dis-tance was 3.1 mm with installation angle of 3.2°,the monitoring accuracy of seeding was the best,which had a sin-gle seed monitoring accuracy of 95.98%,missed seeds monitoring accuracy of 95.91%,and a single seed replay monitoring accuracy of 93.28%.Bench test results showed that when the operation speed of burrow planter was 3-5 km/h,the monitoring accuracy of single seed could be>95%,with monitoring accuracy of miss seeding>91%,monitoring accuracy of replayed>90%.Field experiments results showed that the accuracy of single seed monitor-ing could be>93%,missed sowing monitoring>90%,replay monitoring>88%,when the operating speed was 3-5 km/h.In summary,this air-suction peanut dibbler seeding monitoring system might meet the needs of real-time monitoring of seeding quality in peanut seeding process,provide data reference for actual seeding operations,and ensure higher seeding quality in the whole sowing process.关键词
