【摘要】 讨论了一种采用CAN/1-wire双总线分级网络的温室环境监控系统,系统上层网络采用CAN总线连接HMI和RTU,下层网络采用1-wire总线,连接RTU和各现场环境参数变送器。采用分级网络的温室监测系统管理方便,能够有效地隔离局部故障,提高系统可靠性;系统结构灵活,安装使用方便。更多还原

【Abstract】 This paper discusses a greenhouse monitoring system based on CAN/1-wire double bus hierarchical network,its upper network connects HMI with RTU by CAN bus and its lower network connects RTU with various field environmental parameter transmitters by 1-wire bus.Greenhouses which adopt Monitoring systems based on hierarchical network are convenient to be managed,they can isolate local faults effectively and improve system reliability.In addition,they have flexible structures and people are easy to install and use them.更多还原
