基于光电传感器的精密播种机排种性能监测系统的研究
Research on the sowing performance monitoring system for precision seeders based on photoelectric sensor
摘要
Abstract
Objective] To design a sowing performance monitoring system based on photoelectric method, so as to solve the problems of miss-seeding, re-seeding and lack of precision in seeding volume during the single grain precision seeding process for crops such as corns and beans. [Method]Infrared sensors were applied to capture the pulse signal when the seeds were falling. The signal was processed by a micro-processor, the time gap between successive seed falling was summarized and compared with the designed time gap to obtain the miss-seeding rate, re-seeding rate and seeding volume. Vertical scoop wheel seedmeter was used as the test object to monitor the miss-seeding, re-seeding performance and seeding volume .[Result]The monitoring accuracy rate for single grain of this monitoring system reached 98. 8%. Compared with the results of the test-bed for testing performance of the seedmeter, the monitoring error of miss-seeding rate was below 0. 3%, the monitoring error of re-seeding rate was below 0. 6% and the monitoring accuracy rate of seeding volume was above 94. 4%. [Conclusion] The monitoring system works stably and has high accuracy.关键词
