AI Technical Summary
Technical Problem
Existing technologies struggle to perform targeted fault diagnosis in process equipment based on limited data, especially when distinguishing and identifying fault causes in multiple control loops, resulting in artifact effects and inaccurate fault diagnosis.
Method used
By setting up multiple regulators and central units in the process equipment, and utilizing the conversion between local and global fault diagnosis codes and fault diagnosis deduction logic, combined with expert knowledge and logical conditions, a clear diagnosis of faults can be achieved.
Benefits of technology
It enables targeted diagnosis of faults in process equipment, reduces the impact of artifacts, and improves the accuracy and efficiency of troubleshooting.

Abstract
在用于具有用于调节过程流体的多个调节器(1i)和中央单元的工艺过程设备的控制和 / 或调整系统的故障诊断方法中规定如下步骤：a)获取(200)至少一个调节器专属的调整原始数据如理论值(w)、实际值(s)、理论‑实际差值(d)或控制值(g)；b)通过多个调节器(1i)中的一个基于至少一个所获的调整原始数据产生(300)至少一个尤其局部故障诊断代码(Dj,Dij)；c)将至少一个故障诊断代码(Dj,Dij)从各自调节器(1i)传输(400)至中央单元(3)；d)将源自特定调节器(1i)的和 / 或涉及特定调节器(1i)的局部故障诊断代码(Dj)变换(304,404)为全局故障诊断代码(Dij)，做法是将局部故障诊断代码(Dj,Dij)与调节器专属识别符(Ii)逻辑关联；e)限定(603)用于故障诊断演绎逻辑(γ)的至少一个逻辑条件，使得故障诊断演绎逻辑(γ)在将至少一个逻辑条件应用于至少一个故障诊断代码(Dj,Dij)时将确定预定的演绎结果(K)；f)借助故障诊断演绎逻辑(γ)基于至少一个故障诊断代码(Dj,Dij)在中央单元(3)中确定(500)至少一个演绎结果(K)。
