摘要
提出了基于双CAN总线的农用模块化多CPU网络型环境参数测控仪的设计,将测控仪分为模糊运算通讯、环境参数测量、输出操作控制、环境参数输入显示4部分模块电路,各模块间通过内CAN总线实现数据交换,测控仪可与上位机间通过外CAN总线实现数据交换。测控仪实现多种参数测控及自校正,通用性强、接线简单、工作可靠、维护方便,易于构成大规模设施农业测控系统。
Proposed the modular structure design of the agriculture environment parameters measure and control instrument that based on the double CAN bus and mainly CPU network. The meter is divided into four part of module electric circuits as the fuzzy operation communication, the environment parameter survey, the output operation control, the environment parameter input and display. The instrument realizes various parameters measure, control and self correct. The instrument is strong in general use, simple to connect the line, work dependable, maintenance convenience, apt to constitute the large-scale system for facilities agricultural measurement and control.
