Research and Design of Papermaking Industry Heat Treatment Furnace Groups Wireless Monitor System

In papermaking industry heat treatment furnace temperature monitor and control system, we usually adopt artificial style or conventional instrument technology to realize monitoring and controlling of heating furnace temperature. But due to fluctuation amplitude of furnace temperature is larger, which usually lead to poor production quality appearance. Aiming to this problem, we design a heat treatment furnace grouppsilas temperature intelligent monitor and control system based on single chip microprocessor and wireless communication technology. Each field controller connects with work central station by wireless communication chip nRF401. And work central station connects with upper PC through serial interface MAX232, which realizes heat treatment furnace groupspsila temperature on-line monitor and management system design efficiently. Through papermaking industry heat treatment furnace experiment monitor, system can accurately control heat furnace according to technique requirement in real-time, temperature monitor error is less than plusmn1.5degC, steady-state error absolution is less than 1degC, and can realize alarming notice under setting limit temperature plusmn1degC, as well as communication well with upper PC.
