摘要：Direct drive electro-hydraulic actuator is a new type of hydraulic transmission with easy maintenance and high efficiency,which has been widely used in municipal engineering (such as water pipe network, gas pipe network), nuclear power plants, and other occasions. For these applications, we designed the electro-hydraulic valve actuator based on Internet of things technology(IOT for short). This paper introduces the mechanical structure and the working principle of the direct-drive electro-hydraulic valve actuator,analyzesIOT architecture. Detailed design was carried on according to the IOT architecture and related experiments have been done. The actuator can automatically, accurately control valve opening, be monitored by PCremotely, display device real-time information through LCD and be operated by touch screen. © (2014) Trans Tech Publications, Switzerland.
