[0018] Figure 1 It is a schematic flow chart of an intelligent detection method for a fire extinguishing device provided by a first embodiment of the present invention; Figure 2 It is a schematic diagram of the structure of an intelligent detection device for a fire extinguishing device provided in the second embodiment of the present invention. DETAILED DESCRIPTION

[0019] 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.

[0020] Reference Figure 1 The first embodiment of the present invention provides an intelligent detection method based on a fire extinguishing device, comprising the following steps: S11, obtaining the ambient charging pressure value of the fire extinguishing device, performing calculations, and obtaining the ambient carbon dioxide density value; S12, calculating according to the ambient carbon dioxide density value to obtain an initial time; S13, based on a preset reference carbon dioxide density value and a preset reference time, performing calculation according to the ambient carbon dioxide density value and the initial time to obtain an actual ambient carbon dioxide density value; S14, calculating the average carbon dioxide density value of the fire extinguishing device during the initial time to obtain an average carbon dioxide density value; S15, calculating the predicted carbon dioxide density average value of the fire extinguishing device, and calculating the difference between the average carbon dioxide density value and the predicted carbon dioxide density average value to obtain a carbon dioxide predicted difference value; S16, comparing the carbon dioxide prediction difference with a preset carbon dioxide density threshold; When the predicted carbon dioxide difference is greater than the preset carbon dioxide density threshold, the fire extinguishing device maintenance operation is performed according to the actual environment carbon dioxide density value; when the predicted carbon dioxide difference is less than the preset carbon dioxide density threshold, wait for the next maintenance inspection.

[0021] In step S11, it is necessary to obtain the ambient charging pressure value of the fire extinguishing device and perform calculations to obtain the ambient carbon dioxide density value, including: First, by obtaining the environmental charging pressure value of the fire extinguishing device, the environmental charging pressure value of the fire extinguishing device refers to the internal pressure value measured by the fire extinguishing device in the current environment, which reflects the state of the fire extinguishing agent (such as carbon dioxide) being compressed inside the fire extinguishing device. This charging pressure value is affected by external factors such as ambient temperature, altitude and device usage, and is a key indicator for evaluating the storage and charging status of the fire extinguishing agent in the fire extinguishing device.

[0022] For example, during the fire extinguishing process, the charging pressure value is directly related to the injection speed and diffusion effect of the fire extinguishing agent. If the charging pressure value is too low, the fire extinguishing agent may not achieve the expected injection effect when released, affecting the efficiency of the fire extinguishing device; on the contrary, if the charging pressure value is too high, it may increase the load of the fire extinguishing device and there is a risk of leakage or explosion.

[0023] Next, based on the ambient charging pressure value of the fire extinguishing device, the ambient carbon dioxide density value is calculated, wherein the calculation formula of the ambient carbon dioxide density value is: In the formula, is the ambient carbon dioxide density value; is the ambient charging pressure value; is a proportionality factor based on experimental data.

[0024] It should be noted that the proportionality coefficient It is a key factor, which takes into account the factors of temperature, altitude and humidity, and is calculated through a modified formula. The specific formula is: In the formula, is the actual measured temperature; is the reference temperature; is the actual humidity; is the reference humidity; is the actual altitude; is the reference altitude; , and are correction factors for temperature, humidity and altitude.

[0025] This correction formula can effectively correct the relationship between carbon dioxide density and pressure under different environments. The relationship between carbon dioxide concentrations under different pressures can be linearly adjusted through appropriate proportional coefficients to compensate for the density error caused by pressure differences. In addition, in actual use, the proportional coefficient can be fine-tuned according to external environmental factors (such as temperature, altitude, etc.), thereby improving the environmental adaptability of the fire extinguishing device. For example, under high altitude or low temperature conditions, after adjusting the proportional coefficient, the density value can be calculated closer to the actual situation, ensuring that the device can still maintain normal function under extreme conditions.

[0026] In step S11 of the present invention, by analyzing the change trend of the ambient carbon dioxide density value over time, the operating status of the fire extinguishing device can be evaluated in real time to determine whether its pressurization status is normal. This data not only reflects the carbon dioxide concentration in the current environment, but also provides an effective reference for the change trend of the equipment performance, so that the system can identify and deal with potential performance degradation problems in advance.

[0027] In step S12, it is necessary to calculate according to the ambient carbon dioxide density value to obtain the initial time, including: Specifically, in order to further analyze the carbon dioxide status of the environment in which the fire extinguishing device is located, it is necessary to calculate the initial time based on the environmental carbon dioxide density value. The initial time is a key parameter in the calculation model, which can help determine the change trend and attenuation of the carbon dioxide density in the fire extinguishing device. The calculation formula of the initial time is: In the formula, is the ambient carbon dioxide density value; is the initial time; is the attenuation coefficient; It is a reference coefficient based on experimental data.

[0028] It should be noted that in this formula, the variable It is the ambient carbon dioxide density value. This density value is obtained through real-time detection of the fire extinguishing device, reflecting the concentration of carbon dioxide in the environment of the fire extinguishing device. Through this density value, the system can further analyze the stability and dissipation of the fire extinguishing agent in different environments.

[0029] It should be noted that the The initial time is used to indicate the length of time required for the carbon dioxide density in the fire extinguishing device to decay naturally from the current level. The calculation of this time can help the detection device estimate the storage time and use time of the fire extinguishing agent, and then support the formulation of equipment maintenance and maintenance plans.

[0030] It should be noted that is the attenuation coefficient, which is an important parameter in the formula. The attenuation coefficient represents the rate at which the density of carbon dioxide decreases exponentially over time. For specific fire extinguishing devices, a pressurization experiment will be carried out before leaving the factory. The attenuation characteristics of carbon dioxide are analyzed by filling the device with a standard concentration of carbon dioxide and monitoring its concentration changes under different temperature, humidity and pressure conditions. Through data analysis and exponential attenuation model fitting, the specific attenuation coefficient is determined, thereby optimizing equipment design and material selection, ensuring that the carbon dioxide concentration is effectively maintained in actual use, and extending the effective use time of the fire extinguishing agent.

[0031] It should be noted that It represents the reference carbon dioxide density under ideal conditions and is used to compare with the ambient carbon dioxide density value, thereby reflecting the deviation between the current density value and the ideal conditions. The numerical value is the carbon dioxide concentration density value under standard environmental conditions (such as 0°C, 1 atm, relative humidity 50%). This setting helps to more accurately judge the impact of the actual environment on carbon dioxide.

[0032] In step S12 of the present invention, the initial time is calculated by a formula, which provides an accurate carbon dioxide attenuation prediction for the fire extinguishing device and helps the system to send a maintenance signal in time when needed.

[0033] In step S13, it is necessary to calculate based on the preset reference carbon dioxide density value and the preset reference time, according to the ambient carbon dioxide density value and the initial time, to obtain the actual ambient carbon dioxide density value, including: First, based on the preset reference carbon dioxide density value and its corresponding reference time, combined with the carbon dioxide density value measured in the current environment and the initial time, the real-time actual environmental carbon dioxide density value is calculated. The calculation formula for the actual environmental carbon dioxide density value is: In the formula, is the actual ambient carbon dioxide density; is the ambient carbon dioxide density value; is the initial time; is the reference carbon dioxide density value; For reference time.

[0034] It should be noted that the reference carbon dioxide density value is a standard value set in advance by the system to provide a benchmark for the carbon dioxide content in the environment. For specific fire extinguishing devices, a long-term pressurization monitoring experiment will be carried out before leaving the factory, and the average value of the carbon dioxide density values ​​monitored by the pressurization experiment will be used as the reference carbon dioxide density value. The reference time is the time point when the reference carbon dioxide density value is recorded. The setting of the reference time enables the system to analyze the changes in carbon dioxide concentration at different time points, and calculate the actual carbon dioxide density in combination with the initial time.

[0035] In step S13 of the present invention, the system can accurately calculate the actual carbon dioxide density at the initial time point through the calculation formula of the actual environmental carbon dioxide density value.

[0036] In step S14, it is necessary to calculate the average carbon dioxide density value of the fire extinguishing device during the initial time to obtain the average carbon dioxide density value, including: First, during the initial period, the system will continuously monitor the carbon dioxide concentration in the fire extinguishing environment. These data form a time series within the time period, capturing the dynamic changes in carbon dioxide concentration. In order to obtain an accurate average density value, the system integrates the carbon dioxide concentration data within the time period, thereby calculating the average carbon dioxide density value within the initial time. The calculation formula for the average carbon dioxide density value is: In the formula, is the CO2 value counted during the initial period; is the average carbon dioxide density value; is the initial time.

[0037] It should be noted that is the average carbon dioxide density value during the initial time, Represents the average state of the carbon dioxide concentration level during the time period, indicating the carbon dioxide concentration value at a certain moment in the initial time, which is a function that changes with time; In a specific embodiment, the system integrates the carbon dioxide concentration in the time period according to the concentration value at each time point in the initial time to obtain the average carbon dioxide density value. This average value helps to smooth the change of carbon dioxide concentration, thereby reflecting the overall concentration trend of carbon dioxide in the fire extinguishing environment and avoiding the influence of fluctuations at individual moments on the judgment of the fire extinguishing device.

[0038] In step S14 of the present invention, the calculation of the average carbon dioxide density value has multiple importance in the fire extinguishing system. First, it provides a stable concentration benchmark for the fire extinguishing system, ensuring that the release of carbon dioxide is within a safe range and avoiding excessive concentration from causing harm to the environment and personnel. Second, through the calculation of this average value, the system can better regulate the release of carbon dioxide in subsequent fire extinguishing operations, improving the fire extinguishing effect and accuracy.

[0039] In step S15, it is necessary to calculate the average value of the predicted carbon dioxide density of the fire extinguishing device, and calculate the difference between the average carbon dioxide density value and the predicted carbon dioxide density average value to obtain the carbon dioxide predicted difference value; In a specific embodiment, step S15 is divided into two key steps: first, the predicted average carbon dioxide density of the fire extinguishing device is calculated, and the difference between the average carbon dioxide density value and the predicted average carbon dioxide density value is calculated.

[0040] First, the predicted average carbon dioxide density needs to be calculated. The predicted average carbon dioxide density represents the average carbon dioxide concentration that the fire extinguishing device should reach under normal use conditions. It is a benchmark value calculated based on historical data. The system will collect carbon dioxide concentration data from multiple uses of the fire extinguishing device in the past, and the carbon dioxide concentration value of each use is recorded as ,in Indicates The sum of these historical data and divided by the number of uses can give the average predicted carbon dioxide density of the fire extinguishing device. The specific formula is: In the formula, is the predicted average CO2 density of the fire extinguishing device; It is the fire extinguishing device Carbon dioxide density value at the time of first use; is the preset number of times the fire extinguishing device is used; It should be noted that Represents the total number of times the device has been used under set conditions. Through this calculation, the system obtains a baseline value of carbon dioxide concentration, which can be used as a comparison standard during the fire extinguishing process to measure whether the current carbon dioxide concentration released is in line with historical expectations.

[0041] Secondly, the predicted difference of carbon dioxide is needed. In the actual fire extinguishing operation, after obtaining the average value of predicted carbon dioxide density and the current average carbon dioxide density After that, the system calculates the difference between the two to determine the deviation between the current release concentration and the expected baseline. This difference is called the CO2 prediction difference , the specific calculation formula is: In the formula, is the difference in CO2 predictions; is the average carbon dioxide density value; is the predicted average carbon dioxide density.

[0042] In a specific embodiment, by calculating , the system can promptly identify whether the carbon dioxide concentration in the current fire extinguishing process is within a reasonable range.

[0043] In step S15 of the present invention, this difference calculation process helps the fire extinguishing system to better manage the release of carbon dioxide and ensure that the fire extinguishing device always remains within the effective concentration range. If the set safety threshold is exceeded, the system can automatically adjust the carbon dioxide release strategy to increase or decrease the release concentration in time to avoid potential impacts on the environment or personnel. In addition, through continuous updating and analysis The system can also improve the performance of fire extinguishing equipment by monitoring the changing trends of the fire.

[0044] In step S16, the carbon dioxide prediction difference needs to be compared with a preset carbon dioxide density threshold; When the predicted carbon dioxide difference is greater than the preset carbon dioxide density threshold, a fire extinguishing device maintenance operation is performed according to the actual environment carbon dioxide density value; when the predicted carbon dioxide difference is less than the preset carbon dioxide density threshold, waiting for the next maintenance test, including: By comparing the CO2 prediction difference with the set CO2 density threshold, the system can determine whether the current working status of the fire extinguishing device requires maintenance operation. The specific operation steps include: comparing the difference with the threshold, determining the maintenance operation, and pressurizing and adjusting the CO2 density of the fire extinguishing device.

[0045] In a specific embodiment, the preset carbon dioxide density threshold is usually set within the range of 5% to 15% of the reference carbon dioxide concentration to ensure that the carbon dioxide concentration is sufficient to effectively suppress the flame during fire extinguishing. Taking safety factors into consideration, the upper limit of the threshold is generally 10% to prevent safety hazards caused by excessive concentration. In certain environments, such as high altitude areas, the threshold may be lowered to 4%. In addition, industry standards such as NFPA also provide guidance for threshold setting. By combining these factors, the specific threshold (for example, 6%) set will serve as a benchmark for the system to determine whether the fire extinguishing device needs maintenance.

[0046] Specifically, the system calculates the current CO2 prediction difference, which is the difference between the actual measured CO2 density average and the predicted density average. Then, the system compares the prediction difference with the preset CO2 density threshold. The preset CO2 density threshold is a key parameter, which is usually set according to the performance standards and safety requirements of the device to ensure that when the CO2 density deviates from the normal value, the system can detect it in time and trigger the corresponding maintenance operation.

[0047] Then, after comparing the CO2 prediction difference with the preset threshold, the system will decide whether immediate maintenance operation of the fire extinguishing device is required based on the comparison result.

[0048] Specifically, if the predicted difference is greater than the preset density threshold, it means that the current carbon dioxide concentration of the fire extinguishing device may deviate from the normal range, and the system will enter maintenance mode. At this time, the system will perform a series of maintenance operations based on the actual environmental carbon dioxide density value monitored in real time. This usually indicates that there may be a problem with the performance of the fire extinguishing device, such as insufficient carbon dioxide release or abnormal concentration, so the system will perform maintenance steps such as cleaning, inspection or replacement of parts to ensure the normal operation of the fire extinguishing device.

[0049] Specifically, if the predicted difference is less than or equal to the preset density threshold, it means that the current CO2 concentration of the device is close to the expected level and no immediate maintenance operation is required. The system will remain in monitoring status and wait for the next test to ensure that the concentration performance of the device continues to be observed at subsequent time points.

[0050] Finally, when the system confirms that maintenance operations are required, an important step is also included, which is to pressurize the fire extinguishing device according to the actual carbon dioxide density value of the environment. This pressurization operation refers to re-injecting or adjusting carbon dioxide into the fire extinguishing device so that its internal carbon dioxide density value matches the current carbon dioxide density of the environment. This pressurization process can compensate for possible carbon dioxide leakage or concentration drop inside the fire extinguishing device, thereby restoring the working capacity of the device so that it can effectively release enough carbon dioxide to extinguish the fire in the next fire situation.

[0051] In step S16 of the present invention, through this whole set of operation procedures, the system realizes intelligent monitoring and maintenance of the fire extinguishing device. When the carbon dioxide density in the device deviates from the normal range, the system can quickly analyze and determine whether immediate maintenance is required to ensure the reliability of the device. At the same time, through the pressurization operation, the system ensures that the carbon dioxide density of the fire extinguishing device is always maintained in a state that matches the actual environment.

[0052] The following describes the working process of the present invention using a common scenario as an example. Figure 2 , which is Figure 1 Schematic diagram of the working scenario of the method.

[0053] In a chemical plant, assuming that the fire extinguishing system must maintain long-term reliability and responsiveness in an environment with high temperatures and potential chemical leaks, the management of the carbon dioxide density of the fire extinguishing device is particularly critical. A chemical plant installed a carbon dioxide fire extinguishing device to deal with potential fire hazards. In the plant area, the ambient temperature is high and the altitude is low. These factors will affect the carbon dioxide density inside the fire extinguishing device. Therefore, the system needs to intelligently monitor and maintain the carbon dioxide density and release status inside the device to ensure that the fire extinguishing agent can be released quickly and effectively when a fire occurs. The following is a detailed working process and calculation example for each step.

[0054] Step S11: Obtain the ambient charging pressure value of the fire extinguishing device and calculate the ambient carbon dioxide density value In order to confirm whether the carbon dioxide in the fire extinguishing device is in an ideal charging state, the system first measures the current environmental charging pressure value P1P_1P1. Assuming that the current measured charging pressure value is 500kPa, the system inputs it into the environmental carbon dioxide density calculation formula: Among them, the proportionality coefficient =500 is set based on experimental data. Substituting the data into the equation: This ambient carbon dioxide density value It reflects the pressure status of the fire extinguishing device in the current environment. The pressure value of the fire extinguishing device is affected by the ambient temperature and altitude. For example, at high temperatures, the expansion of carbon dioxide gas may cause the internal pressure to increase, while in a high-altitude low-pressure environment, the carbon dioxide concentration may be low. Therefore, it is necessary to obtain accurate The value is the key for the system to judge the operating status of the device.

[0055] Step S12: Calculate the initial time according to the ambient carbon dioxide density value In order to further understand the decay rate of carbon dioxide density of the fire extinguishing device in a specific environment, the system calculates the initial time through the ambient carbon dioxide density, that is, the natural decay time of the fire extinguishing agent concentration from the current state to the reference value. The time required. The calculation formula is: Assume that the attenuation coefficient set in the system , then: Hour The initial time is the time it takes for the fire extinguishing device to reach the decay benchmark under the current environment. This parameter provides a time scale and a benchmark for pressurization management for subsequent operations. For example, if the system detects that the initial time value is lower than expected, it may indicate that the carbon dioxide density in the device decays faster due to the external environment, which in turn indicates that more frequent pressurization maintenance may be required.

[0056] Step S13: Calculate the actual ambient carbon dioxide density value Next, the system calculates the actual carbon dioxide density of the fire extinguishing device under the current environment based on the preset reference value. and the corresponding reference time Hour.

[0057] The calculation formula is: In the formula, is the actual ambient carbon dioxide density; is the ambient carbon dioxide density value; is the initial time; is the reference carbon dioxide density value; For reference time.

[0058] Substitute the data: This actual ambient carbon dioxide density value It is calculated based on the changing trend of environmental conditions and initial time, and can more accurately reflect the status of the fire extinguishing device in actual operation. A low value indicates that there may be insufficient CO2 in the current extinguishing device and the system may be flagged for inspection and recharge.

[0059] Step S14: Calculate the average carbon dioxide density value within the initial time At the initial time Within hours, the system monitors the changes in carbon dioxide concentration in the fire extinguishing device and records it as a function of concentration. Assuming that multiple data points are collected during this time period, the system calculates the average carbon dioxide density value according to the following formula: In the formula, is the CO2 value counted during the initial period; is the average carbon dioxide density value; is the initial time.

[0060] Assume that the system is integrated to obtain ,This average value is a smoothing of the carbon dioxide concentration in the initial time period, which can eliminate the impact of short-term fluctuations on the system judgment.

[0061] Step S15: Calculate the predicted carbon dioxide density average value and the predicted difference The system further calculates the average predicted CO2 density of the fire extinguishing device from historical data , the current average density value With the predicted value Compare and get the difference in carbon dioxide prediction : The difference It is an important basis for judging whether the current carbon dioxide density of the fire extinguishing device meets the standard. If the difference is too large, it means that the current carbon dioxide concentration is lower than expected, and the system may need to perform pressurization operations or check for abnormalities according to the situation.

[0062] Step S16: Compare the predicted difference with the threshold to determine whether maintenance is required In one specific embodiment, the system predicts the difference With the preset density threshold Therefore, the system determines that the current carbon dioxide concentration of the fire extinguishing device is still within a reasonable range and does not need immediate maintenance. At this time, the system will enter the next monitoring cycle without taking any recharging or maintenance measures.

[0063] In another specific embodiment, during the daily detection process, the system calculates and obtains the following parameters based on the ambient charging pressure value, ambient carbon dioxide density value, initial time, etc. With the preset density threshold Suppose in a certain test, the system concludes , and the preset carbon dioxide density threshold is , then the predicted difference If the set threshold is exceeded, the system determines that the current carbon dioxide density may not be sufficient to achieve the expected fire extinguishing effect and immediate maintenance operations are required.

[0064] In this case, the system will be based on the actual ambient carbon dioxide density value Initiate maintenance operations, including: The system first performs a pressurization operation, that is, replenishing carbon dioxide into the fire extinguishing device to adjust the carbon dioxide density inside to the current ambient density. level to ensure that the carbon dioxide concentration inside the device reaches a safe and sufficient state.

[0065] Secondly, in order to ensure that the performance of the fire extinguishing device meets the standards, the system will start the maintenance process and conduct a comprehensive inspection of key components, including sealing detection, nozzle cleaning and functional testing of gas valves, and replace worn parts when necessary to prevent insufficient density or leakage due to aging or wear of components in high temperature environments in the future.

[0066] Finally, after the pressurization and maintenance operations are completed, the system once again detects the carbon dioxide density inside the fire extinguishing device to ensure that it reaches the preset working range to meet the injection and diffusion requirements in future fire situations.

[0067] After completing the above steps, the system will recalculate the predicted difference and threshold value to confirm that the matching of the carbon dioxide density in the device and the environmental conditions has returned to normal levels. This intelligent monitoring system ensures that the fire extinguishing device can still function quickly and reliably under extreme conditions, thereby ensuring the fire safety protection of the chemical plant.

[0068] Through these steps, the system realizes real-time monitoring and predictive analysis of fire extinguishing equipment.
