摘 要:为了解决大型精播机作业质量的自动监测问题,设计了种、肥作业智能计量监测系统。系统能够完成计量种、肥施播量,监测种箱和肥箱排空以及种管和肥管堵塞等情况。与以往的研究不同的是:采用了间接测量法计量种、肥施播数量,双轮测距法测量作业面积,并采用光电阵列检测种、肥排空及堵塞信息。系统安装在2BJM-9型精播机上进行了田间生产试验,播种量测量相对误差<5%,施肥量测量相对误差<9.6%,作业面积测量相对误差<5.5%,报警最大响应时间为0.8s。通过现场试验,证明其方法可行,监测效果较好,能实现精播机作业的全天候、全过程监测。For solving the problems about automatic testing farming quality and quantity of large scale precision seeder, seed and fertilizer farming intelligent gauging and monitoring system was studied and designed.It can gauge the seeding rate and fertilizer rate,and monitor the blockage of seed and fertilizer spouts,or the emptying of seed and fertilizer boxes. Compared with the past study methods,the differences of the study were:it used indirect method to gauge the seeding rate and fertilizer rate,and to gauge farming area by two-wheel testing distance method.And photoelectric sensors array were used to monitor the blockage of seed and fertilizer spouts,and the emptying of seed and fertilizer boxes.It was installed on the 2BJM-9 precision seeder,and experimented in farm.The relative errors of seeding rate,fertilizer rate and farming area were less than 5%,9.6%,5.5%,respectively.The maximum relay time of alarming was 0.8 s.Field trial showed this method was practicable,and the monitoring effect was better.This system can realize to monitor whole course of precision seeders operating in all-weather.
