制浆造纸行业工艺规程复杂、多样,对系统和设备都有着较高的要求,尤其对系统来说,其可靠的稳定性和较高的灵活性是保证生产工艺顺利进行的前提，在森博一期30万吨项目中，我们采用了HONEYWELL TPS开放型分布过程控制系统，其完善的诊断，组态工具，模块化的软硬件结构，完全满足了系统的连续性和稳定性要求。在二期扩建的100万吨浆项目中，我们再次采用HONEYWELL 新一代控制系统PKS ，到目前为止，我公司的木片输送，给水及污水处理已进行了应用和实践，下面将逐一介绍新一代控制系统的结构、布局和控制方案。

 1．  EPKS硬件组成及结构

        EXPERION PKS 过程控制系统是HONEYWELL新一代过程自动化系统，它的功能高于一般的集成控制系统，其中嵌入式决策支持和诊断技术，为决策者提供了所需信息，其安全组件使安全环境独立于主控系统，也提高了系统整体的安全稳定性。
