制漿造紙行業(yè)工藝規(guī)程復雜、多樣,對系統(tǒng)和設備都有著較高的要求,尤其對系統(tǒng)來說,其可靠的穩(wěn)定性和較高的靈活性是保證生產(chǎn)工藝順利進行的前提，在森博一期30萬噸項目中，我們采用了HONEYWELL TPS開放型分布過程控制系統(tǒng)，其完善的診斷，組態(tài)工具，模塊化的軟硬件結構，完全滿足了系統(tǒng)的連續(xù)性和穩(wěn)定性要求。在二期擴建的100萬噸漿項目中，我們再次采用HONEYWELL 新一代控制系統(tǒng)PKS ，到目前為止，我公司的木片輸送，給水及污水處理已進行了應用和實踐，下面將逐一介紹新一代控制系統(tǒng)的結構、布局和控制方案。

 1．  EPKS硬件組成及結構

        EXPERION PKS 過程控制系統(tǒng)是HONEYWELL新一代過程自動化系統(tǒng)，它的功能高于一般的集成控制系統(tǒng)，其中嵌入式?jīng)Q策支持和診斷技術，為決策者提供了所需信息，其安全組件使安全環(huán)境獨立于主控系統(tǒng)，也提高了系統(tǒng)整體的安全穩(wěn)定性。
