| 摘 要： | 为实现小麦播种作业性能实时监控，设计了一种基于CAN总线的小麦精密播种机播种实时监控系统，阐述了系统总体结构，设计了系统硬件和软件，并进行了田间试验。该系统包括传感器信号采集单元、播种监测模块、CAN 模块和播种监测终端，能够实时监测种管状态、机具前进速度和排种轴转速。采用光电传感器和霍尔传感器分别检测排种管落种状态和地轮转速并输出电压或脉冲信号，播种监测模块根据传感器输出的信号，判断排种管播种状态（正常、堵塞和空管），计算出地轮转速和排种轴转速，并计算出机具前进速度，以上信息通过CAN总线传输给播种监测终端并实时显示。试验结果表明，该系统故障状态监测准确率为>98%，堵塞响应时间<0.2 s，空管报警响应时间<0.5 s。系统工作稳定可靠，抗尘、抗震能力强，能够有效监测小麦播种作业性能。该研究成果能满足小麦播种性能实时监测要求，有助于提高小麦播种作业质量。

| Abstract: | Abstract: To monitor wheat planting performance on real time, a real-time monitoring system of wheat planting performance based on CAN bus was designed. The general structure of the system was elaborate, the hardware and software of the system was designed and the field experiment was conducted. The system included sensor unit for signal collecting, monitoring module, Controller Area Network (CAN) module and terminal, and could monitor the status of seed tube, working speed, rotation velocity of seed shaft. Photoelectric sensor was used to convert quantities of seed tube status into voltage signals, and hall sensor was used to convert quantities of wheel axis rotation velocity into pulse signals. Monitoring module judge the status of seed tube (normal, blocked and missing), and calculate the rotation velocity of wheel axis and seed shaft based on the signals output by sensors. At the same time, monitoring module calculate working speed according to the rotation velocity of wheel axis information. Then the information obtained by monitoring module was uploaded to terminal by CAN bus and displayed on real time on the terminal. The result of the experiment showed that there was no false alarm at the working speed of 10 km/h, the monitoring accuracy of seed tube fault status was >98%, blocked alarm response time <0.2 s, missing alarm response time <0.5 s. The system worked reliably and had a strong ability to anti-dusting and anti-vibration, and effectively monitored wheat planting performance. |
