摘要
联合收割机的液压系统结构复杂,较多的驱动部件承载着巨大的负载变化,故实现联合收割机液压驱动装置的在线监测对于提高联合收割机工作效率具有重要意义。为此,对联合收割机液压监测系统的硬件配置、软件控制系统及故障报警系统进行了设计及优化。系统可以实时采集和显示联合收割机主要工作部件的工作参数,并向用户发出错误工作状态的警报。田间试验结果表明:监测系统的功能和精度完全满足田间作业的要求,故障报警的准确率为96.5%,自动诊断时间小于78s,极大地提高了联合收割机的作业效率。研究结果对于降低田间作业的故障率、提高作业效率、实现联合收割机自动化和智能化发展具有参考价值。
The hydraulic system of combine harvester has a complex structure,and more driving components carry huge load changes.It is important to realize online monitoring of hydraulic drive unit of combine harvester to improve the efficiency of combine harvester.This study designs and optimizes the hardware configuration,software control system and fault alarm system of the combine harvester hydraulic monitoring system,which can collect and display the working parameters of the main working parts of the combine harvester in real time and send alarms to the user about the wrong working status.The results of field experiments show that the function and accuracy of the monitoring system fully meet the requirements of field operation,the accuracy rate of fault alarm is 96.5%,and the automatic diagnosis time of fault alarm is less than 1 minute and 18 seconds,which greatly improves the operation efficiency of combine harvester.The research results are useful for reducing the failure rate of field operation,greatly improving the operation efficiency and realizing the automation and intelligent development of combine harvester.
