The invention provides a method and a device for precisely tracing a root reason for an oil and gas production system alarm signal. The method comprises the following steps: after receiving the alarm signal, acquiring at least two preselected disturbance propagation routes according to a monitoring variable causal relationship built in advance, wherein each preselected disturbance propagation route at least comprises a target monitoring variable causing the alarm signal and a start monitoring variable directing to the target monitoring variable; acquiring correlation coefficients among the adjacent monitoring variables in the preselected disturbance propagation routes, and a disturbance change rate of each monitoring variable; based on the correlation coefficients and the disturbance change rates, acquiring a weight coefficient of the disturbance propagation route of a corresponding place; according to the weight coefficient, determining a target disturbance propagation route; and taking the start monitoring variable in the target disturbance propagation route as the root reason for the alarm signal. By the method and the device, the root reason for the alarm signal in an oil and gas production process can be relatively accurately found.
Description
technical field [0001] The application relates to the field of information technology processing, in particular to a method and device for accurately tracing the root cause of an alarm signal in an oil and gas production system. Background technique [0002] The descriptions in this section merely provide background information related to the disclosure in this application and may not constitute prior art. [0003] As an important part of the current oil and gas production system, such as catalytic cracking and catalytic reforming production systems in the petroleum processing process, the alarm signal can effectively monitor the operation status of the oil and gas production process. When an abnormality occurs in one or several links of the oil and gas production system, the alarm signal will be triggered in the form of sound and light. After receiving the sound and light alarm signal, the operator can take necessary measures to prevent further deterioration of the abnorma...
