为提高插秧机控制系统的可靠性和灵活性,设计了基于CAN总线的分布式控制系统。该系统主要由变速控制模块、水平自动调节控制模块、插植深浅自动调节控制模块以及参数检测和报警模块组成。各控制模块之间采用CAN 2.0总线协议进行数据通信。目前该系统已经完成了装车调试和田间作业试验。结果表明,采用基于CAN总线分布式控制系统的插秧机各项控制功能稳定、可靠,能够满足水田插秧作业要求。 In order to improve the reliability and flexibility of the transplanter control system, a distributed control system based on CAN bus is designed. The system is mainly composed of a variable speed control module, a level automatic adjustment control module, a shading automatic adjustment control module, and a parameter detection and alarm module. The control module uses CAN 2.0 bus protocol for data communication. At present, the system has completed loading and commissioning and field operation test. The results show that the control functions of transplanter based on CAN bus distributed control system are stable and reliable, and can meet the requirements of paddy field planting.
