摘　　要：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。How to design a control system with CAN bus distribution.In order to enhance reliability and maneuverability for a rice-shoot transplanter we designed a distribution type control system therefor based on a CAN bus.The system consists mainly of gear-shift control modes,automatic level readjusting modes,automatic planting-depth readjustment control modes,and data check and warning modes,among which are data communicated with CAN 20 bus.Such a machine is found in stable and reliable performance while meeting operational requirements for rice shoot transplantation in the paddy field.
