摘　　要：根据目前粮食水分快速检测存在的问题,应用电阻法插杆式水分传感器测量原理,研究设计了一种基于现场总线粮食水分快速检测智能节点。节点微控制器采用C8051F041,水分检测点6个,节点和上位机通信运用CAN总线,适用于分布式粮食干燥控制系统。研究设计表明,该节点具有体积小巧、通用性好、抗干扰性能强、造价降低、线路少、维修方便、精度高且抗干扰能力强的特点,可满足分布式粮食干燥控制系统的要求。Based on the existing problems in the rapid detection of grain moisture, using the theory of bar type moisture sensor resistance method to design a method which is used for intelligent nodes of grain moisture detection based on the fieldbus. Micro controller nodes are C8051F041, six moisture testing points, CAN fieldbus is used for nodes and the up- per machine communication, this adapt to distributed grain drying control system. The design indicates that the nodes have the advantages as bellow： small in size, high tensile strength, strong anti-interference performance, low-cost strategy, less line, easy maintenance, high precision ying control system. , which satisfy the performance requirement of distributed grain dr-
