[0105] When the warning module determines to output a warning instruction, it also includes:

[0106] A first preset comprehensive warning coefficient threshold E1, a second preset comprehensive warning coefficient threshold E2, a third preset comprehensive warning coefficient threshold E3, and a fourth preset comprehensive warning coefficient threshold E4 are preset, and E1 = 1.2, E2 = 1.3, E3 = 1.4, and E4 = 1.5;

[0111] It can be understood that in this embodiment, by considering the changes in multiple parameters, including pressure, temperature, flow and stress, the influence of these parameters is comprehensively considered through the comprehensive warning coefficient E0, thereby providing a more comprehensive pipeline status assessment, collecting and analyzing multiple data in real time to quickly identify potential problems, and dynamically adjusting the initial warning coefficient and threshold. The system can accurately adapt to the actual operation of the pipeline and reduce the false alarm rate. Parameter adjustment and decision-making are performed in an automated manner without the need for human intervention, which helps to reduce human errors and improve the stability of the system. Different thresholds and adjustment coefficients allow for customized settings based on the specific needs of the pipeline, which can adapt to different types of pipelines and working conditions. According to the size of the comprehensive warning coefficient E0, different levels of warning instructions K1, K2, K3, and K4 can be selected to help classify and handle emergency situations.

[0112] Furthermore, this embodiment helps improve the safety of pipeline operations, reduce accident risks, and minimize adverse impacts on the environment and personnel through real-time monitoring and multi-parameter comprehensive early warning. It also provides early warning instructions to help operation and maintenance personnel detect problems in a timely manner and reduce maintenance cycles and costs.

[0118] The adjustment module obtains the current warning time point Xi of the output warning instruction of the current warning cycle Ti, and obtains the abnormal initial warning coefficient greater than 1 in the initial warning coefficient in the current warning cycle Ti;

[0119] When the warning module determines to output the warning instruction within the next warning cycle T(i+1), the corresponding next warning time point X(i+1) is obtained;

[0120] Calculate the time difference ΔX between the current warning time point Xi and the next warning time point X(i+1), ΔX=X(i+1)-Xi; pre-set the minimum time difference threshold Xmin;

[0121] When ΔX≤Xmin, the adjustment module determines not to adjust the abnormal initial warning coefficient;

[0122] When ΔX>Xmin, the adjustment module determines to adjust the abnormal initial warning coefficient and restores the abnormal initial warning coefficient to the initial value 1.

[0123] It can be understood that in this embodiment, by considering the time difference ΔX, the initial warning coefficient can be adjusted in a more time-sensitive manner. If the threshold Xmin is exceeded, the abnormal initial warning coefficient can be restored to the initial value 1, avoiding frequent adjustments to the initial warning coefficient in a short period of time, helping to reduce unnecessary system intervention and improve system stability. By restoring the abnormal initial warning coefficient to the initial value 1, the system can ensure the stability of the system in long-term operation, avoid over-adaptation to instantaneous abnormal data, and thus reduce the risk of false alarms and missed alarms.

[0124] Furthermore, the initial warning coefficient adjustment mechanism in this embodiment helps to improve the intelligence and adaptability of the system, ensuring that the pipeline monitoring system can respond to different situations in a timely and accurate manner, while reducing unnecessary manual intervention and improving the operability and reliability of the system.
