CAN总线在海洋数据监控系统中的设计与实现

摘要

In view of actual requirement of remote data monitoring in the marine environment, a hardware and software method of data monitoring system for marine is developed, which is based on the fast and mixed MCU.Using C8051F040 and its built-in function modules as the core of the control system and CAN-bus for the connection of each sensor nodes can form the network of the field sensor nodes, and display real-time the data through host computer. The result shows that the monitoring system can transmit under the rate of 9 600 bit/s normally, stable and applicable in real-time. It has a broad application prospects in the marine environment.%针对海洋环境远程数据监控的实际需要,研制了一种基于高速混合单片机的海洋数据监控系统的硬软件设计方法.该系统利用C8051 F040及其内置模块的功能作为系统的控制核心,利用CAN总线作为控制系统各个传感器节点的连接总线,构成现场传感器节点网络,并通过上位机实时显示现场数据.经实验结果表明,该监控系统在传输速率为9600 bit/s下能正常通信,有较高的实时性和稳定性,在海洋环境中有广泛的应用前景.
