摘　　要：阀门是管道系统中应用最广泛的执行机构。随着机电一体化技术和计算机控制技术的发展,实现阀门的数字化、智能化和网络化已变得十分迫切。为此,将先进的计算机通信技术应用于电动阀门的控制系统中,设计了一种基于Modbus现场总线的智能农用阀门电动执行机构控制系统,实现了农用阀门电动执行机构的自动控制和主从分机之间的数字通信等功能。The valve is one of the most popular actuators which are widely used in the piping system. With the development of electromechanical integration technology and computer control technology, it is very urgent to achieve the digitalization, intelligentization and network of the valve system. A novel design scheme of intelligent electrical valve actuator based on Modbus bus is presented by syncretizing the advanced computer communication technology and the control strategy of the valve system. The automatic control of the electrical valve actuator and the functions of Digital Communication for master slave control can be achieved by using the proposed method.
