摘　　要：笔者针对现有各温室大棚之间存在的通信传输距离短、实时性不强、系统扩展性差、灵活性低等问题,设计了基于CAN总线SJA1000CAN控制器、TJA1050CAN总线收发器、网络控制器、WIFI-CAN总线集中控制器的CAN信息采集系统,并简要介绍了各系统的硬件系统、软件系统和智能节点硬件结构.该系统能实时采集各温室大棚的不同环境信息并及时根据采集的信息自动控制温室环境.Aiming at the problems of short communication distance,weak real-time performance,poor system expansibility and low flexibility among existing greenhouses,a can information acquisition system based on CAN bus SJA1000 can controller,tja1050 can bus transceiver,network controller and wifi-can bus centralized controller is designed.The hardware system,software system and intelligence of each system are briefly introduced Hardware structure of energy node.The system can collect different environmental information of each greenhouse in real time and control the greenhouse environment automatically according to the collected information.
