摘要
在现代化的运输网络系统中,阀门有着举足轻重的作用。然而传统的手动阀门有着很大的局限性,因此结合电阀门和CAN现场总线的优点,本文提出基于电控技术的海通阀,该阀门能够进行远程控制;同时本文阐述CAN现场总线的通信原理、结构以及特点;给出电控阀门驱动设计的整体方案,分析各个模块的功能,着重介绍下位机阀门控制系统的设计原理;最后介绍基于CAN现场总线的通信接口设计原理,分析该总线通讯接口的优点。本设计在阀门控制中采用了CAN总线将上位机与下位机构成一个控制系统,这对通海阀的自动智能化提供了实验和理论依据。
Valve has a pivotal role in the modern transportation network system. But the tradition manual valve has important limitation. Combined with the advantages of the electric valve and CAN fieldbus, this paper proposed a sea valve based on the electronic control technology, which can be controlled remotely. The communication principle, structure and characteristics of CAN fieldbus are analyzed by the paper. The overall design scheme of electronic control valve drive is presented, and the function of each module is analyzed. The design principle of the valve control system is introduced emphatically. At last, the design principle of communication interface based on CAN fieldbus is introduced, and the advantages of the bus communication interface are analyzed. CAN bus is used to combine the upper computer and the lower computer to be an control system, which provides an experimental and theoretical basis for intelligent control of the sea gate vale.
