DEVELOPMENT OF ON-LINE CALIBRATION SYSTEM FOR SAFETY VALVES IN POWER PLANTS BASED ON ARM AND ETHERNET TECHNOLOGY
A new on-line calibration system for safety valves in power plants based on ARM and ethernet technology has been developed
mainly including signal regulation
data acquisition
and embeded processing system.The software of ARM data acqiesition unit adopts embeded Linux operating system to carry out development of applied programme for the networks
through interface of ethernet to realize communication with upper computer(PC) to complete on-line calibration of safety valves.The highly accurate pressure transducer and valve stem displacement sensor have been selected
boasting superiority in many aspects
such as algorithm for signal processing
velocity and accuracy in data acquisition
compatibility and expandibility of the interface etc.
can more accurately judge the open pressure of the safety valves
