Problems solved by technology
Through the existing two-level alarm setting value, it can help users understand the alarm level of the current real-time monitoring data, that is, the risk level of the site, so as to take corresponding control measures; but the section from the first level alarm to the second level alarm Due to the inability to judge the speed of the risk development trend, the enterprise cannot prevent the control measures in advance or the prevention speed is too slow before the secondary alarm triggers the corresponding control measures, resulting in serious losses for the enterprise due to the control measures

Embodiment Construction
[0018] The technical solutions of the present invention will be described in further detail below through specific implementation methods.
[0019] Such as figure 1 As shown, a risk trend deduction and hierarchical early warning method based on online monitoring data includes the following steps:
[0020] When the online monitoring data is greater than the first-level alarm threshold, query the historical monitoring data, identify and obtain the (n-1) wave peaks closest to the online monitoring data, and form a reference number set (t 1 ,y 1 ), (t 2 ,y 2 ), (t 3 ,y 3 )...(t n ,y n );
[0021] Among them, y 1 is the online monitoring data, t 1 is the monitoring time corresponding to the online monitoring data, y 2 is the first wave peak closest to the online monitoring data, t 2 is the monitoring time corresponding to the first peak value; y i is the i-1th peak value closest to the online monitoring data, t i is the monitoring time corresponding to the i-1th peak ...

The invention provides a risk trend deduction and grading early warning method based on online monitoring data, and the method comprises the following steps: querying historical monitoring data when the online monitoring data is greater than a first-level alarm threshold value, recognizing and obtaining (n1) crest values nearest to the online monitoring data, and forming a reference number set with the online monitoring data; performing trend fitting on the reference number set to obtain a trend fitting curve equation y = a + bt; wherein b is a parameter representing the speed of the development trend; and comparing the parameter b with a plurality of preset graded early warning thresholds, and carrying out graded early warning according to a comparison result. The historical monitoring data of the online monitoring and early warning system is fully utilized, the development trend of the risk of the monitoring point data in a future period of time is deduced by means of the time sequence analysis model, and the risk is subjected to graded early warning and information pushing according to the deducing result in combination with the acceptable degree of the risk of an enterprise, sothat a supervisor prejudges in advance. Pertinent management and control measures are taken.
Description
technical field [0001] The invention relates to the field of safety monitoring and early warning, in particular to a risk trend deduction and hierarchical early warning method based on online monitoring data. Background technique [0002] The safety monitoring and early warning system is one of the important technical prevention means to realize the safety risk prevention and management of major hazards, key equipment and key areas. In recent years, the state has put forward more and more strict requirements on the installation and use of safety monitoring and early warning systems and the closed-loop management of early warning information. [0003] At this stage, the online monitoring and early warning systems installed by enterprises generally set two-level alarm thresholds according to the on-site working conditions. GB / T50493-2019 "Petrochemical Combustible and Toxic Gas Detection and Alarm Design" stipulates that the first-level alarm setting value of flammable gas is...
