摘　　要：对目前国内海洋水文气象观测系统数据采集部分进行了分析,针对数据采集系统结构封闭、传感器互换性差、系统无法灵活升级等存在的问题提出了解决方案。将国际上广泛应用在汽车和电梯控制系统以及其他工业现场的CAN总线技术应用到海洋观测系统当中。根据海洋水文气象观测的业务需求和海洋环境的特殊性并结合CAN总线的特点,以基于CAN2.0B规范的iCAN应用层协议为基础,设计了通用性分布式海洋水文气象观测数据采集系统原型。经过对该原型系统的性能测试及连续运行,验证了该原型的合理性和可用性。该原型结构可根据海洋自动观测站和志愿船等不同的观测环境和业务需求进行适当扩充和裁剪。对提高海洋观测系统的扩展性和通用性具有重要意义。The data acquisition component of China＇s current marine hydro-meteorological observation system is analyzed in this paper, so as to put forward a solution to tackle the problems of the data acquisition system, like closed structure, poor interchangeability of sensors and unavailability of update for the system. CAN-bus, a technology widely used in the control systems of motor vehicles and elevators across the world, has been introduced into the ocean observation system. In view of the professional requirements of ocean observation, and combined with the characteristics of the CAN-bus and the marine environment, a general distributing data acquisition prototype for ocean observation is designed on the foundation of iCAN application layer protocols in line with the CAN2.0B standard. Through performance tests and continuous operation, the prototype has proved reasonable and usable. The prototype structure is able to be extended or cut out according to different environments and professional requirements of ocean observation onshore and offshore. The findings are attached significance for improving the expansibility and universality of the ocean observation system.
