花生收获机智能工况测控系统设计

Design of Working-condition Detecting and Controlling System for Peanut Harvester

针对花生收获机智能化的需求,介绍了一种花生收获机工况检测与控制系统的设计方案。该系统对花生收获机工作状况进行监测与信息反馈,可在手动和自动两种工作模式下完成工作机构控制。其主控制器采用力士乐控制器,通过CAN总线与各工作机构检测部件通讯,根据当前的运行模式和运行状况做出控制决策,控制电液系统驱动的执行机构完成收获作业。经田间试验验证,系统功能良好。

To meet the need of peanut harvester intelligentization, a design scheme working-condition detecting and con- trolling system for peanut harvester is introduced in this paper. The system can monitor working condition of peanut har- vester and feedback the information through CAN bus. The system can work in both manual and automatic control mode to accomplish the harvest work. Rexroth controller is used as the main controller, which communicate with detection com- ponents in different parts through CAN bus. According to the current operation mode and operation condition, the con- troller makes decisions to control actuator which is driven by electro-hydraulic system to complete harvest task. System function is tested by field experiment and proved to be good.
