Abstract
It is a broad application to measure and control temperature in the industry production.Especially in some industry,such as oil,chemistry,electric power,metallurgy,it is a very importand tache to measure and control temperature,temperature parameter is an important index in industry control situation.
The paper mainly researches the application in kinds of temperature control situations in the industry field based on ARM9 construct and embedded Linux system. Presently the control projects normally are PLC and SCM. PLC normally aims at single project or small repetition project, lacks in agility and volume, the cost is higher comparatively; SCM is mainly used in the minitype equipment, the cost and the power is lower, the efficiency is higher, but it is hard to transplant. In order to adapt to the improvement of information industry, the paper focuses on strongpoints, weakpoints and applied fields of PLC and SCM, and puts forward to adopt ARM9 embedded micro controller and Linux operation system to control the temperature. It has a good expansibility, dependability, fast response speed, small volume, offers a new type control project to users.
