为了将水产养殖中的溶解氧进行采集并可靠地远传和存储,设计了基于CAN总线和嵌入式USB主机的智能溶解氧传感器系统.将CAN总线应用到水产养殖的现场环境中,利用CAN总线的实时性、可靠性和灵活性,能够实时显示水环境中的溶解氧含量,并可以与上位机进行通信.嵌入式USB主机可以脱离PC独立运行,将采集的数据保存到移动USB存储设备中,扩展了系统的存储容量.该系统为溶解氧浓度的控制提供了可靠的数据,具有良好的应用前景.%In order to collect dissolved oxygen in aquaculture and implement reliable transmission and storage, the intelligent dissolved-oxygen sensor system based on CAN bus and embedded USB host computer is designed. It can apply CAN bus to aquaculture field environment By realtime , reliability and flexibility of the CAN bus, it can display the dissolved oxygen content in water environment, and communicate with the PC. The embedded USB host can operate independently from PC, and save the collected data to the USB mobile storage device, extend the system's storage capacity. The system provides reliable data for control of the dissolved oxygen concentratin. It has good application prospects.
