| titleOfInvention | Method for quickly positioning oscillation signal during complex chemical process |
| abstract | The invention discloses a method for quickly positioning an oscillation signal during a complex chemical process. Specific to the characteristics of large scale, strong nonlinearity, strong coupling, and the like of the present complex chemical process, a propagation path of the oscillation signal is searched and a fault source is accurately positioned. The method comprises the following steps: signifying an original signal; obtaining signifying dynamic information of the signal; calculating directed signifying mutual information of each path of signal and obtaining signal transmission direction and coupling strength; and lastly, positioning variables of the fault source from a cause and effect matrix. According to the method, the chemical process is directly utilized to measure the variables and no disturbance is added to a working condition; a fault position during the large-scale chemical process is accurately positioned; the calculation is easy and the implementation is convenient; the method can be easily realized on a host computer of present extensively applied DCS (Data Communication System) or industrial control system; the maintenance cost of the large-scale complex process is reduced; the risk of improving and promoting the control property is reduced; and the benefit is increased. |
