Description

Technical Field

[0001] The present invention belongs to the technical field of oil and gas storage and transportation control and management, and specifically relates to a centralized alarm system for an oil and gas storage and transportation regional control and management center. Background Art

[0002] In the field of oil and gas storage and transportation, along with the large-scale development and transportation of oil and gas resources, the oil and gas storage and transportation regional control center shoulders the vital responsibility of safety management. As the core facility for storing oil and gas resources in the oil and gas storage and transportation area, the safety of storage tanks is in the first place.

[0003] At present, the continuous growth of oil and gas demand has promoted the continuous expansion of storage and transportation infrastructure, and the number, volume and distribution range of storage tanks have shown a significant growth trend. However, the traditional decentralized and isolated storage tank alarm mechanism has been difficult to adapt to the current needs. Therefore, in order to achieve all-round real-time monitoring and centralized management of storage tank safety, a centralized alarm system for the control center needs to be established urgently.

[0004] In the prior art, there are also some solutions related to tank alarm control that can be applied to oil and gas storage and transportation areas. For example, China Patent Publication No. CN117831240A is a tank liquid level slope alarm method and device, which obtains the monitoring status of the tank. If the monitoring status is a static monitoring status, the static calculation slope is obtained, and a static alarm is performed according to the static calculation slope and the static set slope. If the monitoring status is a dynamic monitoring status, the shape of the tank is obtained. If the tank is a regular shape tank, the first dynamic calculation slope is obtained, and a first dynamic alarm is performed according to the first dynamic calculation slope and the first dynamic setting slope. If the tank is an irregular shape tank, the second dynamic calculation slope is obtained, and a second dynamic alarm is performed according to the second dynamic calculation slope and the second dynamic setting slope. By performing static alarm and dynamic alarm on the tank respectively, the relevant status alarms of the oil storage tank can be monitored more accurately.

[0005] Another Chinese patent publication number CN102930687B is a fire alarm system suitable for inflammable and explosive places such as large oil storage tanks. It includes a pressure-bearing device, a temperature sensing device and an alarm device, which can achieve full coverage of the detection area, eliminate fire blind spots, and effectively reduce operating costs.

[0006] Although the above schemes put forward some relevant solutions that can be applied to the alarm control of storage tanks in oil and gas storage and transportation areas, the existing technology still has the following limitations, specifically: 1. The existing storage tank alarm system in oil and gas storage and transportation areas generally adopts alarm rules based on a unified fixed alarm threshold, which is difficult to adapt to complex and changeable actual working conditions. For example, in different seasons, different storage media and different operation stages of storage tanks, the normal fluctuation range of parameters such as pressure, temperature, and liquid level in the storage tank will change. The fixed alarm threshold makes the storage tank alarm system unreliable and inaccurate, which may lead to frequent false alarms or missed alarms.

[0007] 2. The existing oil and gas storage and transportation area tank alarm system lacks an effective self-checking mechanism, which limits the adaptive adjustment and optimization capabilities of the tank alarm system. Summary of the invention

[0008] In order to overcome the shortcomings of the background technology, an embodiment of the present invention provides a centralized alarm system for an oil and gas storage and transportation area control center, which can effectively solve the problems involved in the above-mentioned background technology.

[0009] The purpose of the present invention can be achieved through the following technical solutions: a centralized alarm system for oil and gas storage and transportation area control center, including: a regular self-inspection planning module, a self-inspection process startup module, a correction demand judgment module and a configuration parameter determination module.

[0010] The periodic self-check planning module is connected to the self-check process starting module, the self-check process starting module is connected to the correction requirement judgment module, and the correction requirement judgment module is connected to the configuration parameter determination module.

[0011] The regular self-inspection planning module is used to plan the regular self-inspection time sequence of the storage tank alarm rules in the target oil and gas storage and transportation area, and determine the date of each self-inspection and the corresponding control cycle.

[0012] The self-inspection process startup module is used to start the self-inspection process of the target oil and gas storage and transportation area tank alarm rules on the current self-inspection date, and retrieve the configuration parameters of the target oil and gas storage and transportation area tank alarm rules in the previous self-inspection control cycle, including the alarm thresholds of various indicators corresponding to various types of tanks in various operating states, where each indicator includes pressure, temperature and liquid level.

[0013] The correction demand judgment module is used to collect the tank alarm event record set and tank operation monitoring data set of the target oil and gas storage and transportation area in the previous self-inspection and control cycle, and determine whether there is a correction need for the configuration parameters of the tank alarm rules of the target oil and gas storage and transportation area in the previous self-inspection and control cycle, and obtain the reference configuration parameters of the tank alarm rules of the target oil and gas storage and transportation area in the current self-inspection and control cycle.

[0014] The configuration parameter determination module is used to consider the environmental change factors of the current self-inspection and control cycle, adjust the reference configuration parameters of the tank alarm rules of the target oil and gas storage and transportation area of ​​the current self-inspection and control cycle, and determine and feedback the configuration parameters of the tank alarm rules of the target oil and gas storage and transportation area of ​​the current self-inspection and control cycle.

[0015] The tank alarm event record set includes the occurrence time of each tank alarm event, the operation status logic indicator, the alarm verification feedback indicator, the tank number involved and the indicator alarm value involved, wherein the operation status logic indicator outputs 0 or 1, 0 indicates non-loading and unloading operation status, 1 indicates oil loading operation status, and the alarm verification feedback indicator outputs the feedback risk level of manual verification of the tank alarm event; the tank operation monitoring data set includes the monitoring values ​​of each indicator corresponding to each type of tank at each unit time point on each day in history.

[0016] The judgment of whether there is a need to modify the configuration parameters of the target oil and gas storage and transportation area tank alarm rules in the previous self-checking and control cycle includes: sorting out the alarm values ​​and alarm verification feedback indicators of each tank alarm event of each indicator involved in the non-loading and unloading operation state of each type of storage tank in the target oil and gas storage and transportation area in the previous self-checking and control cycle according to the tank type corresponding to each tank number in the target oil and gas storage and transportation area, and evaluating the setting sensitivity of the alarm threshold of each indicator corresponding to each type of storage tank in the non-loading and unloading operation state of the target oil and gas storage and transportation area in the previous self-checking and control cycle ,in The serial numbers of various types of storage tanks in the target oil and gas storage and transportation area. is the number of each indicator, .

[0017] Sorting out the monitoring values ​​of each indicator at each unit time point during the non-loading and unloading operation state and no alarm period for various types of storage tanks in the target oil and gas storage and transportation area on each day of the previous self-inspection and control cycle, and evaluating the rationality of the setting of the alarm thresholds of various indicators corresponding to various types of storage tanks in the non-loading and unloading operation state in the target oil and gas storage and transportation area of ​​the previous self-inspection and control cycle .

[0018] Will As the judgment condition for the need to correct the alarm thresholds of various indicators corresponding to various storage tanks in the target oil and gas storage and transportation area in the non-loading and unloading operation state in the previous self-inspection control cycle, A preset benchmark value of reasonableness is set for the alarm threshold of the indicator corresponding to the non-loading and unloading operation status of the storage tanks in the target oil and gas storage and transportation area.

[0019] Said The specific evaluation process includes: calculating the alarm exceeding thresholds of each tank alarm event for each indicator involved in the non-loading and unloading operation state of various types of storage tanks in the target oil and gas storage and transportation area in the previous self-inspection and control cycle, and analyzing the alarm exceeding correlation ratio of each indicator involved in the non-loading and unloading operation state of various types of storage tanks in the target oil and gas storage and transportation area in the previous self-inspection and control cycle. .

[0020] According to the preset tank risk weights corresponding to the risk levels of each feedback of the manual verification tank alarm event, combined with the alarm verification feedback indicators, the preset tank risk weights corresponding to each tank alarm event of each indicator involved in the non-loading and unloading operation state of various types of tanks in the target oil and gas storage and transportation area in the previous self-inspection control cycle are obtained, and the alarm risk correlation ratios of various indicators involved in the non-loading and unloading operation state of various types of tanks in the target oil and gas storage and transportation area in the previous self-inspection control cycle are analyzed. .

[0021] By formula Evaluate the setting sensitivity of the alarm thresholds of various indicators corresponding to various types of storage tanks in the target oil and gas storage and transportation area in the previous self-inspection and control cycle in the non-loading and unloading operation state, among which They are respectively the preset weights corresponding to the alarm excess correlation ratio and the alarm risk correlation ratio. , is a natural constant, They are respectively the preset reasonable thresholds of the alarm over-range correlation ratio and the alarm risk correlation ratio of the corresponding indicators of the non-loading and unloading operation status of the storage tanks in the target oil and gas storage and transportation area, express .

[0022] Said The specific evaluation process includes: defining the normal monitoring value fluctuation range of each indicator corresponding to various types of storage tanks in the target oil and gas storage and transportation area during the previous self-inspection and control cycle during the non-loading and unloading operation state and the no-alarm period, and calculating the buffer rationality index relative to the alarm threshold.

[0023] The number of times the monitoring values ​​of various indicators of various storage tanks in the target oil and gas storage and transportation area in the last self-inspection and control cycle were outside the normal monitoring value fluctuation range and triggered tank alarm events was counted; combined with the deviation ratio between the alarm value and the normal monitoring value fluctuation range when the tank alarm event was triggered each time, the response rationality index of various indicators corresponding to the alarm threshold of various storage tanks in the target oil and gas storage and transportation area in the last self-inspection and control cycle in the non-loading and unloading operation state was analyzed.

[0024] The buffer rationality index is added to the response rationality index to obtain the rationality of the setting of the alarm thresholds of various indicators corresponding to various types of storage tanks in the target oil and gas storage and transportation area in the previous self-inspection and control cycle in the non-loading and unloading operation state.

[0025] The judgment of whether there is a need to modify the configuration parameters of the alarm rules of the target oil and gas storage and transportation area in the previous self-inspection and control cycle also includes: sorting out the monitoring values ​​of each indicator corresponding to each unit time point of each type of storage tank in the target oil and gas storage and transportation area in the oil filling operation state in each day of the previous self-inspection and control cycle, and calculating the average value of the change rate of each indicator monitoring value corresponding to each type of storage tank in the target oil and gas storage and transportation area in the oil filling operation state in the previous self-inspection and control cycle and standard deviation ,by Plan the permissible tolerance interval of each indicator alarm threshold corresponding to the oil loading operation status of various storage tanks in the target oil and gas storage and transportation area in the previous self-inspection control cycle relative to the non-loading and unloading operation status, among which The confidence coefficient is preset to determine the allowable tolerance of each indicator relative to the alarm threshold of various types of storage tanks in the target oil and gas storage and transportation area in the oil filling operation state. .

[0026] Obtain the reference alarm thresholds for each indicator corresponding to various types of storage tanks in the target oil and gas storage and transportation area in the current self-inspection control cycle in the non-loading and unloading operation state , according to the formula Obtain the potential planning alarm thresholds for each indicator of each type of storage tank in the target oil and gas storage and transportation area in the current self-inspection and control cycle in the oil filling operation state, and the alarm thresholds for each indicator of each type of storage tank in the target oil and gas storage and transportation area in the previous self-inspection and control cycle in the oil filling operation state Make a comparison.

[0027] like , it is judged that there is a need to correct the alarm thresholds of various indicators corresponding to the oil filling operation status of various types of storage tanks in the target oil and gas storage and transportation area in the previous self-inspection control cycle, and As the reference alarm thresholds for various indicators corresponding to the oil filling operation status of various types of storage tanks in the oil and gas storage and transportation area of ​​the current self-inspection control cycle, , then it is judged that there is no need for correction, and It continues to serve as the reference alarm threshold for each indicator corresponding to the oil filling operation status of various types of storage tanks in the target oil and gas storage and transportation area of ​​the current self-inspection and control cycle.

[0028] The specific process of obtaining the preset confidence coefficient is: setting a series of different values ​​of the confidence coefficient, performing simulated backtesting simulation based on the alarm values ​​of each tank alarm event of each indicator involved in the oil filling operation status of various types of tanks in the target oil and gas storage and transportation area in the previous self-inspection and control cycle, and selecting the confidence coefficient value corresponding to the optimal balance point as the preset optimal confidence coefficient.

[0029] The optimal balance point satisfies the condition that the comprehensive evaluation value of the false alarm rate and the missed alarm rate of the simulation results is the lowest.

[0030] Said The specific acquisition process includes: if there is a need to correct the alarm threshold of a certain indicator corresponding to a certain type of storage tank in the target oil and gas storage and transportation area of ​​the previous self-inspection control cycle in a non-loading and unloading operation state, extract the setting sensitivity of the alarm threshold of the indicator corresponding to this type of storage tank in the target oil and gas storage and transportation area of ​​the previous self-inspection control cycle in a non-loading and unloading operation state ,like , it means that the sensitivity of the alarm threshold of this indicator for this type of tank in the non-loading and unloading state is low and needs to be lowered. , it means that the sensitivity of the alarm threshold of this indicator for this type of tank in the non-loading and unloading state is too high and needs to be adjusted upward. The calculation formula for the specific adjustment value is ,in The sensitivity of the unit is set to the preset indicator control value, thereby obtaining the reference alarm threshold value of each indicator corresponding to various types of storage tanks in the target oil and gas storage and transportation area in the current self-inspection and control cycle in the non-loading and unloading operation state.

[0031] The method for determining the configuration parameters of the alarm rules for storage tanks in the target oil and gas storage and transportation area during the current self-inspection and control cycle includes: obtaining the environmental change temperature value and the environmental change humidity value of the target oil and gas storage and transportation area during the current self-inspection and control cycle relative to the previous self-inspection and control cycle, and analyzing the adjustment values ​​of the alarm thresholds of various indicators of various types of storage tanks for the environmental changes in the current self-inspection and control cycle of the target oil and gas storage and transportation area relative to the previous self-inspection and control cycle according to the preset correlation coefficients of the environmental changes in the current self-inspection and control cycle of the target oil and gas storage and transportation area relative to the previous self-inspection and control cycle, so as to adjust the reference alarm thresholds of various indicators corresponding to various types of storage tanks in the target oil and gas storage and transportation area during the current self-inspection and control cycle in each operating state, and determine the configuration parameters of the alarm rules for storage tanks in the target oil and gas storage and transportation area during the current self-inspection and control cycle.

[0032] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects: (1) The present invention promotes the orderly inspection of the tank alarm rules by planning the regular self-inspection time sequence of the tank alarm rules in the target oil and gas storage and transportation area, and provides systematic guarantee for the continuous and stable operation of the tank alarm system in the target oil and gas storage and transportation area, thereby improving management efficiency and reliability.

[0033] (2) The present invention retrieves the configuration parameters of the alarm rules for storage tanks in the target oil and gas storage and transportation area in the previous self-inspection and control cycle to carry out correction demand judgment, clarifies the reference alarm thresholds of various indicators corresponding to various types of storage tanks in the target oil and gas storage and transportation area in the current self-inspection and control cycle in each operating state, and continuously improves the safety management level of storage tanks in the oil and gas storage and transportation area in a data-driven intelligent management manner.

[0034] (3) The present invention adjusts the reference configuration parameters of the alarm rules for storage tanks in the target oil and gas storage and transportation area during the current self-inspection and control period by considering the environmental change factors during the current self-inspection and control period, thereby helping to improve the adaptability and flexibility of the alarm control of storage tanks in the target oil and gas storage and transportation area, effectively reducing the risks of false alarms and missed alarms, and ensuring the effectiveness of storage tank safety management.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0040] refer to Figure 1 As shown, the present invention provides a centralized alarm system for oil and gas storage and transportation regional control centers, including: a regular self-inspection planning module, a self-inspection process startup module, a correction demand judgment module and a configuration parameter determination module.

[0041] The periodic self-check planning module is connected to the self-check process starting module, the self-check process starting module is connected to the correction requirement judgment module, and the correction requirement judgment module is connected to the configuration parameter determination module.

[0042] The periodic self-inspection planning module is used to plan the periodic self-inspection time sequence of the storage tank alarm rules in the target oil and gas storage and transportation area, and determine the date of each self-inspection and the corresponding control cycle.

[0043] The embodiment of the present invention plans a regular self-inspection time sequence of the tank alarm rules in the target oil and gas storage and transportation area, thereby promoting the orderly inspection of the tank alarm rules, providing systematic guarantee for the continuous and stable operation of the tank alarm system in the target oil and gas storage and transportation area, thereby improving management efficiency and reliability.

[0044] The self-inspection process startup module is used to start the self-inspection process of the target oil and gas storage and transportation area tank alarm rules on the current self-inspection date, and retrieve the configuration parameters of the target oil and gas storage and transportation area tank alarm rules in the previous self-inspection control cycle, including the alarm thresholds of various indicators corresponding to various types of tanks in various operating states, where each indicator includes pressure, temperature and liquid level.

[0045] It should be noted that the alarm thresholds of various indicators corresponding to various types of storage tanks in various operating states in the present invention all focus on the alarm upper limits, namely, the temperature upper limit, the liquid level upper limit and the pressure upper limit.

[0046] The correction requirement judgment module is used to collect the tank alarm event record set and tank operation monitoring data set of the target oil and gas storage and transportation area in the previous self-inspection and control cycle, and determine whether there is a correction requirement for the configuration parameters of the tank alarm rules of the target oil and gas storage and transportation area in the previous self-inspection and control cycle, and obtain the reference configuration parameters of the tank alarm rules of the target oil and gas storage and transportation area in the current self-inspection and control cycle accordingly.

[0047] Specifically, the tank alarm event record set includes the occurrence time of each tank alarm event, the operation status logic indicator, the alarm verification feedback indicator, the tank number involved and the indicator alarm value involved, wherein the operation status logic indicator outputs 0 or 1, 0 indicates non-loading and unloading operation status, and 1 indicates oil loading operation status, and the alarm verification feedback indicator outputs the feedback risk level of manual verification of the tank alarm event.

[0048] It should be noted that the above-mentioned occurrence time is accurate to a specific time point on a certain date.

[0049] The storage tank operation monitoring data set includes monitoring values ​​of various indicators corresponding to various types of storage tanks at various unit time points on various days in history.

[0050] It should be noted that the tank alarm event record set of the target oil and gas storage and transportation area in the previous self-inspection and control cycle is obtained by feedback from the automated alarm devices deployed inside various types of storage tanks, among which the alarm verification feedback indicators are obtained by on-site inspection and evaluation and uploaded by professional maintenance personnel in the target oil and gas storage and transportation area, and the tank operation monitoring data set is obtained by real-time monitoring and upload by pressure sensors, temperature sensors and liquid level sensors distributed inside various types of storage tanks.

[0051] refer to Figure 2As shown, specifically, the judgment as to whether there is a need to modify the configuration parameters of the alarm rules for the storage tanks in the target oil and gas storage and transportation area of ​​the previous self-inspection and control cycle includes: sorting out the alarm values ​​and alarm verification feedback indicators of each tank alarm event of each indicator involved in the non-loading and unloading operation state of each type of storage tank in the target oil and gas storage and transportation area of ​​the previous self-inspection and control cycle according to the storage tank type corresponding to each tank number in the target oil and gas storage and transportation area, and evaluating the setting sensitivity of the alarm threshold values ​​of each indicator corresponding to the non-loading and unloading operation state of each type of storage tank in the target oil and gas storage and transportation area of ​​the previous self-inspection and control cycle. ,in The serial numbers of various types of storage tanks in the target oil and gas storage and transportation area. is the number of each indicator, .

[0052] Sorting out the monitoring values ​​of each indicator at each unit time point during the non-loading and unloading operation state and no alarm period for various types of storage tanks in the target oil and gas storage and transportation area on each day of the previous self-inspection and control cycle, and evaluating the rationality of the setting of the alarm thresholds of various indicators corresponding to various types of storage tanks in the non-loading and unloading operation state in the target oil and gas storage and transportation area of ​​the previous self-inspection and control cycle .

[0053] Will As the judgment condition for the need to correct the alarm thresholds of various indicators corresponding to various storage tanks in the target oil and gas storage and transportation area in the non-loading and unloading operation state in the previous self-inspection control cycle, A preset benchmark value of reasonableness is set for the alarm threshold of the indicator corresponding to the non-loading and unloading operation status of the storage tanks in the target oil and gas storage and transportation area.

[0054] Specifically, the The specific evaluation process includes: calculating the alarm thresholds of each tank alarm event involving each indicator of each type of tank in the target oil and gas storage and transportation area in the previous self-inspection control cycle in the non-loading and unloading state ,in is the number of each tank alarm event, Calculate the alarm excess correlation ratio of various indicators involved in the non-loading and unloading operation state of various types of storage tanks in the target oil and gas storage and transportation area in the previous self-inspection control cycle , ,in Preset reasonable alarm exceeding thresholds for tank alarm event indicators.

[0055] It should be noted that the above The specific calculation process is as follows: subtract the alarm values ​​of each tank alarm event of each indicator involved in the non-loading and unloading operation state of each type of storage tank in the target oil and gas storage and transportation area in the previous self-inspection and control cycle from the alarm threshold of the corresponding indicator involved in the non-loading and unloading operation state of the corresponding tank type, so as to obtain the alarm exceeding threshold value of each tank alarm event of each indicator involved in the non-loading and unloading operation state of each type of storage tank in the target oil and gas storage and transportation area in the previous self-inspection and control cycle.

[0056] According to the preset tank risk weights corresponding to the risk levels of each feedback of the manual verification tank alarm event, combined with the alarm verification feedback indicators, the preset tank risk weights corresponding to each tank alarm event of each indicator involved in the non-loading and unloading operation state of various types of tanks in the target oil and gas storage and transportation area in the previous self-inspection control cycle are obtained. , analyze the alarm risk correlation ratio of various indicators involved in the non-loading and unloading operation status of various types of storage tanks in the target oil and gas storage and transportation area during the previous self-inspection and control cycle , ,in A preset tank risk weight threshold corresponds to a low risk level of a tank alarm event.

[0057] By formula Evaluate the setting sensitivity of the alarm thresholds of various indicators corresponding to various types of storage tanks in the target oil and gas storage and transportation area in the previous self-inspection and control cycle in the non-loading and unloading operation state, among which They are respectively the preset weights corresponding to the alarm excess correlation ratio and the alarm risk correlation ratio. is a natural constant, They are respectively the preset reasonable thresholds of the alarm over-range correlation ratio and the alarm risk correlation ratio of the corresponding indicators of the non-loading and unloading operation status of the storage tanks in the target oil and gas storage and transportation area, express .

[0058] It should be noted that the analysis logic of the alarm threshold setting sensitivity is as follows: In an ideal state, the tank alarm device will trigger the alarm action at the moment the indicator reaches the preset alarm threshold. However, in actual operation scenarios, due to the interaction of multiple complex factors, the situation is not so simple and direct.

[0059] First, from the perspective of the time dimension of system response, there is inevitably a system response delay from the moment the indicator monitoring sensor detects that the indicator has reached the set alarm threshold to the moment the alarm signal is successfully sent and fully recorded. During the short delay period, the value of the monitored indicator often has the possibility of continuing to rise, which directly causes the indicator alarm value that is finally recorded to slightly exceed the originally set alarm threshold.

[0060] Secondly, considering the physical properties of the oil and gas inside the tank and the external environmental interference factors, the oil and gas inside the tank are always in a dynamic change process, and its pressure, liquid level, temperature and other indicators will fluctuate due to various factors. At the same time, sudden external factors such as the start and stop of equipment around the tank, the rapid opening or closing of pipeline valves, and lightning strikes may instantly cause sudden peaks in the indicator values. In view of these complex and changeable situations, in order to ensure that the tank can operate safely and stably to the greatest extent, a certain safety margin is usually reserved when setting the alarm threshold. For example, taking the pressure indicator as an example, when the pressure actually exceeds 0.005MPa, it is defined as reaching the alarm standard, but when setting the alarm threshold, it is often set to 0.0045MPa, so as to effectively prevent the risk caused by excessively high alarm values ​​due to various emergencies.

[0061] The core function of the alarm over-range correlation ratio is to accurately reflect the degree of over-threshold of the alarm value relative to the alarm threshold. Once the alarm event has a large over-threshold amplitude and its proportion is high, it will imply that the setting of the alarm threshold may be defective and fail to accurately capture the abnormal changes in the parameters. Or, from another perspective, since the alarm threshold is set with a certain safety margin, allowing the indicator value to rise within a certain range, it is also possible that the indicator monitoring value has actually been in an abnormal state for a long time, but the alarm threshold has not responded in time. It is inferred that the setting sensitivity of the alarm threshold is at a low level and needs to be adjusted downward appropriately.

[0062] The main function of the alarm risk correlation ratio is to intuitively present the degree of close correlation between alarm events and actual risks, such as safety accidents and potential major safety hazards. When the alarm risk correlation ratio is low, it means that the connection between alarm events and actual risks is relatively weak, and a large amount of alarm information may not be necessary information that is closely related to the actual risk, reflecting that the sensitivity of the alarm threshold setting is too high, and the alarm threshold needs to be appropriately adjusted upward. However, in the process of comprehensively evaluating the sensitivity of alarm threshold settings, from the macro perspective of overall safety, the weight of the alarm risk correlation ratio in the entire evaluation system should be lower than the alarm over-limit correlation ratio. The combined alarm over-limit correlation ratio and the alarm risk correlation ratio can fully show the actual sensitivity of the indicator alarm threshold setting.

[0063] For example, the above The specific values ​​can be 0.6 or 0.4.

[0064] Specifically, the The specific evaluation process includes: sorting out the monitoring values ​​of each indicator at each unit time point during the non-loading and unloading operation state and no alarm period of various types of storage tanks in the target oil and gas storage and transportation area on each day of the previous self-inspection and control cycle, planning the probability density curve of each indicator during the non-loading and unloading operation state and no alarm period of various types of storage tanks in the target oil and gas storage and transportation area of ​​the previous self-inspection and control cycle through kernel density estimation, taking the median of the data distribution corresponding to the probability density curve as the starting point, and gradually traversing the data points to the left and right sides respectively. During the traversal process, the cumulative probability of the covered data points is continuously calculated until the cumulative probability reaches the preset probability value. At this time, the monitoring value interval corresponding to the left and right sides is the normal monitoring value fluctuation interval, thereby defining the normal monitoring value fluctuation interval of each indicator during the non-loading and unloading operation state and no alarm period of various types of storage tanks in the target oil and gas storage and transportation area of ​​the previous self-inspection and control cycle, and calculating the buffer rationality index relative to the alarm threshold. .

[0065] It should be noted that the above The specific calculation process is as follows: extract the upper limit of the normal monitoring value fluctuation range of each indicator corresponding to each type of storage tank in the target oil and gas storage and transportation area in the previous self-inspection control cycle during the non-loading and unloading operation state and no alarm period , extract the alarm thresholds of various indicators corresponding to various types of storage tanks in the target oil and gas storage and transportation area in the previous self-inspection control cycle in the non-loading and unloading operation state , according to the formula Obtain the buffer rationality index of the normal monitoring value fluctuation range of each indicator relative to the alarm threshold of various types of storage tanks in the target oil and gas storage and transportation area in the previous self-inspection control cycle during the non-loading and unloading operation state and no alarm period, where It is the preset safety buffer margin of the normal monitoring value fluctuation range of the tank indicators relative to the alarm threshold.

[0066] The number of occurrences of the phenomenon that the corresponding monitoring values ​​of various indicators of various types of storage tanks in the target oil and gas storage and transportation area in the previous self-inspection and control cycle are outside the normal monitoring value fluctuation range and trigger tank alarm events in the non-loading and unloading operation state is counted, and the ratio analysis is performed with the total number of tank alarm events involving the corresponding indicators of the corresponding storage tank types in the target oil and gas storage and transportation area in the previous self-inspection and control cycle in the non-loading and unloading operation state. Obtain the ratio of the number of occurrences of the corresponding monitoring values ​​of various indicators of various types of storage tanks in the target oil and gas storage and transportation area in the previous self-inspection and control cycle in the non-loading and unloading operation state that are outside the normal monitoring value fluctuation range and trigger tank alarm events. , combined with the deviation ratio between the alarm value and the normal monitoring value fluctuation range when each tank alarm event is triggered , It is the number of each time when the indicator monitoring value is outside the normal monitoring value fluctuation range and triggers the tank alarm event. , analyze the response rationality index of various indicators relative to the alarm threshold of various types of storage tanks in the target oil and gas storage and transportation area in the previous self-inspection and control cycle in the non-loading and unloading operation state .

[0067] It should be noted that the above The specific analysis process is: extract the upper limit of the preset reasonable deviation range of the tank index monitoring value relative to the normal monitoring value fluctuation range and lower limit , extract the monitoring value of the tank index outside the normal monitoring value fluctuation range and the preset reasonable number of occurrences of the triggering tank alarm event is greater than the upper limit of the range and lower limit , or , set the response rationality index to , otherwise set the response rationality index to , The number of times the index monitoring value is outside the normal monitoring value fluctuation range that triggers the tank alarm event, thereby obtaining the response rationality index of various types of tanks in the target oil and gas storage and transportation area in the previous self-inspection control cycle in the non-loading and unloading state corresponding to each index relative to the alarm threshold , , .

[0068] The buffer rationality index is added to the response rationality index to obtain the rationality of the setting of the alarm thresholds of various indicators corresponding to various types of storage tanks in the target oil and gas storage and transportation area in the previous self-inspection and control cycle in the non-loading and unloading operation state.

[0069] It should be noted that the above analysis logic on the rationality of alarm threshold setting is explained as follows: The buffer rationality index focuses on evaluating whether there is an appropriate buffer space between the fluctuation range of the routine monitoring value of the indicator and the corresponding alarm preset value during non-loading and unloading operations. The appropriate buffer spacing helps to accurately identify the normal fluctuations and abnormal changes of the indicator, which serves as one of the reference factors for evaluating the rationality of the alarm threshold setting.

[0070] The response rationality index focuses on the proportion of indicators exceeding the limits of the normal monitoring value fluctuation range and causing the tank alarm to occur, and the rationality of the relationship between the indicators and the average amplitude of the indicators exceeding the normal monitoring value fluctuation range. If the proportion of events that trigger an alarm when the indicator exceeds the normal monitoring value fluctuation range is high, but the average deviation ratio is low, it means that the indicator triggers an alarm when it only slightly exceeds the normal monitoring value fluctuation range. On the contrary, if the proportion of events that trigger an alarm when the indicator exceeds the normal monitoring value fluctuation range is low, and the average deviation ratio is significantly high, it means that the alarm threshold fails to give a timely warning for potential risks, and there is a risk of underreporting. This is used as the second reference factor for evaluating the rationality of the alarm threshold setting.

[0071] refer to Figure 3 As shown, specifically, the method of judging whether there is a need to modify the configuration parameters of the alarm rules for the target oil and gas storage and transportation area in the previous self-inspection and control cycle also includes: sorting out the monitoring values ​​of each indicator corresponding to each unit time point of each type of storage tank in the target oil and gas storage and transportation area in the oil filling operation state on each day of the previous self-inspection and control cycle, and calculating the average value of the change rate of each indicator monitoring value corresponding to each type of storage tank in the oil filling operation state in the target oil and gas storage and transportation area in the previous self-inspection and control cycle. and standard deviation ,by Plan the permissible tolerance interval of each indicator alarm threshold corresponding to the oil loading operation status of various storage tanks in the target oil and gas storage and transportation area in the previous self-inspection control cycle relative to the non-loading and unloading operation status, among which The confidence coefficient is preset to determine the allowable tolerance of each indicator relative to the alarm threshold of various types of storage tanks in the target oil and gas storage and transportation area in the oil filling operation state. .

[0072] It should be noted that the present invention uniformly determines the allowable tolerance of each indicator of the oil loading operation status of various types of storage tanks in the target oil and gas storage and transportation area relative to the alarm threshold as the upper limit value of the allowable tolerance range of each indicator alarm threshold corresponding to the oil loading operation status of various types of storage tanks in the target oil and gas storage and transportation area relative to the non-loading and unloading operation status in the previous self-inspection and control cycle.

[0073] Obtain the reference alarm thresholds for each indicator corresponding to various types of storage tanks in the target oil and gas storage and transportation area in the current self-inspection control cycle in the non-loading and unloading operation state , according to the formula Obtain the potential planning alarm thresholds for each indicator of each type of storage tank in the target oil and gas storage and transportation area in the current self-inspection and control cycle in the oil filling operation state, and the alarm thresholds for each indicator of each type of storage tank in the target oil and gas storage and transportation area in the previous self-inspection and control cycle in the oil filling operation state Make a comparison.

[0074] like , it is judged that there is a need to correct the alarm thresholds of various indicators corresponding to the oil filling operation status of various types of storage tanks in the target oil and gas storage and transportation area in the previous self-inspection control cycle, and As the reference alarm thresholds for various indicators corresponding to the oil filling operation status of various types of storage tanks in the oil and gas storage and transportation area of ​​the current self-inspection control cycle, , then it is judged that there is no need for correction, and It continues to serve as the reference alarm threshold for each indicator corresponding to the oil filling operation status of various types of storage tanks in the target oil and gas storage and transportation area of ​​the current self-inspection and control cycle.

[0075] Specifically, the specific process of obtaining the preset confidence coefficient is: setting a series of different values ​​of the confidence coefficient, performing simulated backtesting simulation based on the alarm values ​​of each tank alarm event of each indicator involved in the oil filling operation status of various types of tanks in the target oil and gas storage and transportation area in the previous self-inspection and control cycle, and selecting the confidence coefficient value corresponding to the optimal balance point as the preset optimal confidence coefficient.

[0076] Specifically, the optimal balance point satisfies the condition that the comprehensive evaluation value of the false alarm rate and the missed alarm rate of the simulation result is the lowest.

[0077] It should be noted that the comprehensive evaluation values ​​of the false alarm rate and the missed alarm rate of the simulation results mentioned above specifically refer to the cumulative value of the products of the false alarm rate and the missed alarm rate of the simulation results and their corresponding preset weights.

[0078] Specifically, the The specific acquisition process includes: if there is a need to correct the alarm threshold of a certain indicator corresponding to a certain type of storage tank in the target oil and gas storage and transportation area of ​​the previous self-inspection control cycle in a non-loading and unloading operation state, extract the setting sensitivity of the alarm threshold of the indicator corresponding to this type of storage tank in the target oil and gas storage and transportation area of ​​the previous self-inspection control cycle in a non-loading and unloading operation state ,like , it means that the sensitivity of the alarm threshold of this indicator for this type of tank in the non-loading and unloading state is low and needs to be lowered. , it means that the sensitivity of the alarm threshold of this indicator for this type of tank in the non-loading and unloading state is too high and needs to be adjusted upward. The calculation formula for the specific adjustment value is ,in The sensitivity of the unit is set to the preset indicator control value, thereby obtaining the reference alarm threshold value of each indicator corresponding to various types of storage tanks in the target oil and gas storage and transportation area in the current self-inspection and control cycle in the non-loading and unloading operation state.

[0079] The embodiment of the present invention retrieves the configuration parameters of the alarm rules for storage tanks in the target oil and gas storage and transportation area of ​​the previous self-inspection and control cycle to carry out correction demand judgment, clarifies the reference alarm thresholds of various indicators corresponding to various types of storage tanks in the target oil and gas storage and transportation area of ​​the current self-inspection and control cycle in various operating states, and continuously improves the safety management level of storage tanks in the oil and gas storage and transportation area in a data-driven intelligent management manner.

[0081] Specifically, the configuration parameters of the alarm rules for storage tanks in the target oil and gas storage and transportation area during the current self-inspection and control cycle are determined, including: obtaining the environmental change temperature value and environmental change humidity value of the target oil and gas storage and transportation area during the current self-inspection and control cycle relative to the previous self-inspection and control cycle, and analyzing the adjustment values ​​of the alarm thresholds of various indicators of various types of tanks for the environmental changes in the current self-inspection and control cycle of the target oil and gas storage and transportation area relative to the previous self-inspection and control cycle according to the preset correlation coefficients of the environmental changes in the current self-inspection and control cycle of the target oil and gas storage and transportation area relative to the previous self-inspection and control cycle, so as to adjust the reference alarm thresholds of various indicators corresponding to various types of tanks in the target oil and gas storage and transportation area in each operating state during the current self-inspection and control cycle, and determine the configuration parameters of the alarm rules for storage tanks in the target oil and gas storage and transportation area during the current self-inspection and control cycle.

[0082] It should be noted that the analysis process of the adjustment value of the alarm threshold of each indicator of each type of storage tank for the environmental changes in the current self-inspection and control cycle of the above-mentioned target oil and gas storage and transportation area relative to the previous self-inspection and control cycle is as follows: multiply the preset correlation coefficient between the indicators corresponding to each type of storage tank in the target oil and gas storage and transportation area and the ambient temperature by the environmental change temperature value of the current self-inspection and control cycle of the target oil and gas storage and transportation area relative to the previous self-inspection and control cycle, and obtain the change value of each indicator corresponding to each type of storage tank in the target oil and gas storage and transportation area in the current self-inspection and control cycle affected by the ambient temperature. Similarly, obtain the change value of each indicator corresponding to each type of storage tank in the target oil and gas storage and transportation area in the current self-inspection and control cycle affected by the ambient humidity, accumulate the change values ​​affected by the ambient temperature and the change values ​​affected by the ambient humidity, and obtain the comprehensive change value of each indicator corresponding to each type of storage tank in the target oil and gas storage and transportation area in the current self-inspection and control cycle affected by the environment. After standardized processing, the adjustment value of the alarm threshold of each indicator of each type of storage tank for the environmental changes in the current self-inspection and control cycle of the target oil and gas storage and transportation area relative to the previous self-inspection and control cycle is obtained.

[0083] The embodiment of the present invention takes into account the environmental change factors of the current self-inspection and control cycle, adjusts the reference configuration parameters of the alarm rules of the target oil and gas storage and transportation area tanks in the current self-inspection and control cycle, helps to improve the adaptability and flexibility of the alarm control of the target oil and gas storage and transportation area tanks, effectively reduces the risks of false alarms and missed alarms, and ensures the effectiveness of tank safety management.
