DISTRIBUTED CONTROL SYSTEM

摘要

A distributed control system permits local or remote control of equipment. T he distributed control system provides a communication bridge through a local control panel between a non-real-time network, such as an Ethernet, and a re al- time network, such as a controller area network. Both soft real-time and har d real-time networks are suitable, but hard real-time is preferred. The system uses multiple distributed control units to control various equipment components and is thus highly expandable. The distributed control system may be applied in any environment. When applied to a skid-mounted coiled tubing unit, the distributed control system reduces the amount of hydraulic hose required and therefore makes set up and take down shorter and more economica l.
