| Abstract: | A kind of intelligent zirconium oxide oxygen analyzer based on the fieldbus is introduced in this paper.The whole structure of the system and the hardware and the software design of the temperature control system are elabo- rated in detail.PID expert controller based on expert intelligent and PID is adopted in temperature control system. PID parameters are modified with output of knowledge base for expert system to change PID control mode.The re- sult indicates that temperature control system of the fiddbus intelligent zirconium oxide oxygen analyzer has improved the precision,reliability,maintainability and testing ability of the instrumention,which has lots of merits compared with the traditional oxygen analyzer. |
