摘　　要：针对稻麦变量施肥机施肥状态监测方法可靠性差等问题,研究设计一种稻麦变量施肥机施肥状态监测方法。该方法用RFP-602薄膜压力传感器来检测排肥管中肥料颗粒的下落状态,对施肥系统的施肥状态进行监测。首先通过仿真试验对RFP-602薄膜压力传感器进行可行性验证;其次使用数字示波器来采集和储存薄膜压力传感器产生的信号,以小波包变换对信号进行能量分解得到特征向量;最后把特征向量导入BP神经网络模型进行识别训练得到分类器,训练得到的分类器经过效果检验后写入单片机,单片机与排肥管上传感器相连接就可以实现监测方法的广泛应用。试验结果表明:该方法监测精度可达95.3%。实现对稻麦播种机施肥系统排肥管堵塞问题的状态监测。In order to solve the problem of poor reliability of fertilizer condition monitoring method of rice and wheat variable fertilizer machine, we designed a new method. This method used rfp-602 thin film pressure sensor to detect the falling state of fertilizer particles in the fertilizer discharge pipe and monitored the fertilization state of the fertilization system. Firstly, the feasibility of rfp-602 thin film pressure sensor was verified by simulation test. Secondly, digital oscilloscope is used to collect and store the signal generated by the thin film pressure sensor. Finally, the feature vector is imported into the BP neural network model for recognition training to obtain the classifier, which is then written into the single-chip microcomputer after effect testing. The test results show that the monitoring accuracy can reach 95.3%m this method can be used to monitor the status of clogging of discharge pipe of rice and wheat seeder fertilization system.
