摘要
针对农田小气候采集具有环境特殊和要求灵活多样等特点,采用嵌入式技术设计了一种模块化气象要素采集系统。在分布式CAN总线基础上,应用层采用CANopen协议实现网络管理服务和报文传送协议。试验结果表明,主控制器和分采集器之间的数据通信可靠、准确,可满足气候采集需求。
For the microclimate in the fields collector has the characteristics of special capture circumstances and flexible collection requirements, a module optimal design of the acquisition system was conducive to the collection elements changes. A distributed network based on CAN bus was designed. One of CAN high layer protocol, CANopen was analyzed and adopted to realize the system communication. Verified by the test and operation of the real system, the data communication between master and slave is reliable and accurate, meets requirements of measurement system.
