Description

Technical Field

[0001] The present invention relates to the field of early warning systems, and in particular to a chemical process safety early warning system based on data analysis. Background Art

[0002] During the operation of chemical parks, safety issues cannot be ignored. Therefore, safety construction usually needs to be considered at the initial stage of the layout of chemical parks. Existing chemical park safety warnings usually collect necessary data at various locations in the chemical park by deploying sensors and other collection equipment, and upload the collected data to the server or central processor for analysis, and issue warnings to the chemical park based on the analysis results; At present, the early warning for chemical parks basically relies on the real-time alarm method of sensors in the park. Although this method can achieve a certain degree of safety early warning, it is too dependent on the collected data. When there is a delay or loss in the data transmission process, or the instantaneous data volume is large, it will cause the safety early warning to lag and affect the safety early warning effect. At the same time, for some safety hazards, real-time early warning relying on data will lead to insufficient early warning, resulting in insufficient time to maintain and eliminate safety hazards.

[0003] In view of the above technical problems, this application proposes a solution. Summary of the invention

[0004] The present invention collects and classifies environmental conditions in the operating environment of chemical equipment, analyzes the environmental interference risks of chemical equipment according to the collected environmental conditions, and then makes corrections in combination with the operating conditions of the chemical equipment itself to obtain the risk conditions in the processing and production process of the chemical equipment, and makes graded warnings of different degrees according to the risk conditions. When there are risks in the chemical processing equipment, timely reminders can be made for maintenance and repair to eliminate potential safety hazards, thereby avoiding the occurrence of risk accidents. The problem that early warnings in chemical parks rely on real-time data, resulting in insufficient advance warnings and inability to fully maintain and eliminate potential safety hazards in advance is solved, and a chemical processing safety early warning system based on data analysis is proposed.

[0005] The purpose of the present invention can be achieved through the following technical solutions: A chemical processing safety early warning system based on data analysis, comprising an environmental interference capture unit, an operation monitoring unit, a collection and summary unit, a comprehensive analysis unit, a fluctuation early warning unit and a numerical early warning unit, wherein the environmental interference capture unit can capture environmental information, analyze the acquired environmental information, and obtain an environmental interference value; The operation monitoring unit can monitor the operation status of the chemical equipment, and analyze the monitored operation parameters of the chemical equipment to obtain the equipment operation status; The collection and summary unit performs a comprehensive analysis on the environmental interference value and the equipment operation status, generates a comprehensive evaluation value according to the analysis result, and sends the comprehensive evaluation value to the comprehensive analysis unit; The comprehensive analysis unit performs analysis based on the comprehensive evaluation value to obtain an equipment safety warning, and distributes the equipment safety warning to the fluctuation warning unit and the numerical warning unit; The fluctuation warning unit is used to identify the equipment fluctuation safety warning and generate a fluctuation safety alarm according to the identification result; The numerical warning unit is used to identify the general warning of the equipment and generate the general safety alarm of the equipment according to the identification result.

[0006] As a preferred implementation of the present invention, the environmental information acquired by the environmental interference capturing unit includes environmental temperature interference and environmental gas interference. The environmental interference capturing unit performs weighted averaging of the environmental temperature interference and the environmental gas interference through a formula to obtain an environmental interference value.

[0007] As a preferred embodiment of the present invention, the method for the environmental interference capturing unit to obtain the environmental temperature interference is: The environmental interference capture unit monitors the ambient temperature through a sensor, and compares the monitored ambient temperature with a set ambient temperature range. If the ambient temperature is outside the set ambient temperature range, the difference between the ambient temperature and the two end values ​​of the ambient temperature range is calculated, and a smaller set of differences is recorded as the ambient temperature difference. The environmental interference capture unit obtains the midpoint of the ambient temperature range, and calculates the ratio of the ambient temperature difference to the midpoint of the ambient temperature range to obtain a temperature difference ratio. If the ambient temperature is within the set ambient temperature range, the temperature difference ratio is recorded as 0.

[0008] As a preferred embodiment of the present invention, the environmental interference capture unit collects the ambient temperature multiple times at different times, summarizes the temperature difference ratio collected each time, and draws a temperature difference ratio change curve in a coordinate system, wherein the horizontal axis of the temperature difference ratio change curve is the number of times the ambient temperature is collected, and the vertical axis of the temperature difference ratio change curve is the temperature difference ratio value; The environmental interference capturing unit calculates the area of ​​a figure enclosed by the temperature difference proportional variation curve and the horizontal axis, and uses the result of the area calculation as the environmental interference value.

[0009] As a preferred embodiment of the present invention, the method for the environmental interference capturing unit to obtain environmental gas interference is: The environmental interference capture unit acquires component parameters of the environmental gas, and divides the component parameters into risk parameters and common parameters according to the composition of the environmental gas. The environmental interference capture unit performs threshold analysis on the risk parameters, and generates a gas risk signal and a gas safety signal according to the analysis results.

[0010] As a preferred embodiment of the present invention, the chemical equipment operation parameters acquired by the operation monitoring unit include operation failure rate and maintenance interval; The operation monitoring unit compares the operation failure rate with a set failure rate threshold to obtain a high failure rate signal or a normal failure rate signal; The operation monitoring unit compares the maintenance interval with the set interval threshold to obtain an insufficient maintenance signal or a normal maintenance signal. The operation monitoring unit records the excessive failure rate signal, normal failure rate signal, insufficient maintenance signal and normal maintenance signal as the equipment operation status.

[0011] As a preferred implementation of the present invention, the collection and aggregation unit generates a corresponding correction coefficient according to the operation status of the equipment, and corrects the environmental interference value by the correction coefficient to obtain a comprehensive evaluation value; The comprehensive analysis unit analyzes the comprehensive evaluation value with the set high and low thresholds.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the environmental conditions in the operating environment of chemical equipment are classified and collected, and the environmental interference risks of chemical equipment are analyzed based on the collected environmental conditions. Then, combined with the correction of the operating conditions of the chemical equipment itself, the risk conditions in the processing and production process of the chemical equipment are obtained, and graded warnings of different degrees are carried out according to the risk conditions. Therefore, when there are risks in the chemical processing equipment, the management personnel can be notified in time to carry out maintenance and repair to eliminate safety hazards, thereby avoiding the occurrence of risk accidents, and greatly improving the advance time of the warning.

[0015] 2. In the present invention, when warning chemical equipment, graded warnings are carried out according to warning values ​​of different levels, and high-risk warnings, low-risk warnings and critical thresholds of warnings are analyzed at the same time to confirm the warning gap between low-risk warnings and high-risk warnings, and the probability of low-risk warnings turning into high-risk warnings is analyzed to achieve further accurate warnings of graded safety alarms.

[0018] The technical scheme of the present invention will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1: See also Figure 1 - Figure 2 As shown, a chemical process safety early warning system based on data analysis includes an environmental interference capture unit, an operation monitoring unit, a collection and summary unit, a comprehensive analysis unit, a fluctuation early warning unit and a numerical early warning unit. The environmental interference capture unit can capture environmental information. The environmental information obtained by the environmental interference capture unit includes environmental temperature interference and environmental gas interference. The method for the environmental interference capture unit to obtain the environmental temperature interference is: The environmental interference capture unit monitors the ambient temperature through a sensor, and compares the monitored ambient temperature with the set ambient temperature range. If the ambient temperature is outside the set ambient temperature range, the difference between the ambient temperature and the two end values ​​of the ambient temperature range is calculated, and the smaller set of differences is recorded as the ambient temperature difference. The environmental interference capture unit obtains the midpoint of the ambient temperature range, and calculates the ratio of the ambient temperature difference to the midpoint of the ambient temperature range to obtain the temperature difference ratio; If the ambient temperature is within the set ambient temperature range, the temperature difference ratio is recorded as 0; The environmental interference capture unit collects the ambient temperature multiple times at different times, summarizes the temperature difference ratio collected each time, and draws a temperature difference ratio change curve in the coordinate system, wherein the horizontal axis of the temperature difference ratio change curve is the number of times the ambient temperature is collected, and the vertical axis of the temperature difference ratio change curve is the temperature difference ratio value; The environmental interference capture unit calculates the area of ​​the figure enclosed by the temperature difference proportional change curve and the horizontal axis, and uses the result of the area calculation as the environmental interference value; The method for the environmental interference capture unit to obtain environmental gas interference is: The environmental interference capture unit obtains the component parameters of the environmental gas, and divides the component parameters into risk parameters and common parameters according to the composition of the environmental gas. The environmental interference capture unit performs threshold analysis on the risk parameters. If the risk parameter is greater than the set fixed threshold, a gas risk signal is generated. If the risk parameter is not greater than the set threshold, a gas safety signal is generated. The environmental interference capture unit uses the formula to perform weighted average of the environmental temperature interference and the environmental gas interference to obtain the environmental interference value GH. , where q and k are the set weight coefficients. The values ​​of q and k are determined by the raw materials used in the chemical processing environment and the processing technology environment requirements. When the risk of gas leakage during chemical processing is higher, the value of k relative to q is larger. When the process requirements during chemical processing are higher, the value of q relative to k is larger. The operation monitoring unit can monitor the operation status of the chemical equipment and analyze the monitored operation parameters of the chemical equipment. The operation parameters of the chemical equipment obtained by the operation monitoring unit include the operation failure rate and maintenance interval; The operation monitoring unit compares the operation failure rate with the set failure rate threshold to obtain a high failure rate signal or a normal failure rate signal; The operation monitoring unit compares the maintenance interval with the set interval threshold to obtain an insufficient maintenance signal or a normal maintenance signal. The operation monitoring unit records the excessive failure rate signal, the normal failure rate signal, the insufficient maintenance signal and the normal maintenance signal as the equipment operation status; The collection and summary unit generates corresponding fault correction coefficients and maintenance correction coefficients according to the equipment operation status, wherein the correction coefficient corresponding to the excessively high fault rate signal is greater than the correction coefficient corresponding to the normal fault rate signal, the correction coefficient corresponding to the insufficient maintenance signal is greater than the correction coefficient corresponding to the normal maintenance signal, and all correction coefficients are greater than 1. The environmental interference value GH is multiplied and corrected by the fault correction coefficient and the maintenance correction coefficient to obtain a comprehensive evaluation value, and the comprehensive evaluation value is sent to the comprehensive analysis unit; The comprehensive analysis unit analyzes the comprehensive evaluation value with the set high and low thresholds. If the comprehensive evaluation value is greater than the set high threshold, a high-risk equipment alarm is generated. If the comprehensive evaluation value is between the set high threshold and the set low threshold, a low-risk equipment alarm is generated. If the comprehensive evaluation value is less than the set low threshold, a normal equipment signal is generated. Both high-risk equipment alarms and low-risk equipment alarms belong to equipment safety warnings. The comprehensive analysis unit distributes the equipment safety warning to the fluctuation warning unit and the numerical warning unit.

[0020] Embodiment 2: See also Figure 1 - Figure 2 As shown, after the fluctuation warning unit obtains the low-risk alarm of the equipment, it obtains the comprehensive evaluation value through the comprehensive analysis unit, and calculates the ratio of the comprehensive evaluation value to the set high threshold to obtain the critical ratio; The fluctuation warning unit compares the critical ratio with the set critical threshold. If the critical ratio is greater than the set critical threshold, a fluctuation safety alarm is generated. If the critical ratio is not greater than the set critical threshold, a fluctuation low-risk warning is generated. After obtaining a high-risk alarm from the equipment, the numerical warning unit generates a regular safety alarm for the equipment. After obtaining a low-risk alarm from the equipment, it generates a safety warning for the equipment. After obtaining a normal signal from the equipment, it does not respond.
