[0002] Level measurement is the process of determining the height or position of the liquid surface in a container, tank, reservoir, well or other liquid storage facility using a variety of sensors, instruments or methods.

[0003] The Chinese patent with publication number CN110108335A discloses a liquid level measurement method, a liquid level measurement device, a liquid level detector and a storage medium. The method mainly obtains the detection data of the angle measuring instrument and calculates the height difference of the float according to the detection data and the length of the movable rod. The liquid level measurement method calculates the height difference of the float by the detection data of the angle measuring instrument, thereby determining the height difference of the liquid surface. The detection accuracy is high, the performance is relatively stable, and the cost is low. Although the above patent solves the problem of liquid level measurement, the following problems still exist in actual operation:

[0004] 1. Each measuring device is not effectively tested, and the measurement data is not further processed, resulting in inaccurate raw data collection.

[0005] 2. Failure to conduct more careful data analysis on the collected measurement data and to use the analyzed data for further adjustment of the liquid pump resulted in the inability to accurately adjust the operating speed.

[0006] 3. There is no continuous monitoring of the liquid pump adjustment process, and no effective data display and early warning of the parameter data during the adjustment process, which results in the staff being unable to obtain the liquid level adjustment status in a timely manner. Summary of the invention

The setting of the alarm intensity enables the system to respond in a graded manner according to the severity of the abnormal situation, thereby improving the efficiency of emergency processing. According to the difference in alarm intensity in the abnormal liquid level data, the adjustment parameters of the liquid pump in the liquid level data to be adjusted can be automatically adjusted, thereby realizing intelligent liquid level adjustment, and prioritizing different risk assessment results to ensure that high-risk problems are dealt with first, and then medium and low-risk problems are dealt with, thereby improving the efficiency and effect of problem handling.

[0112] Specifically, through the strict inspection process of the measurement device installation inspection unit, it is ensured that all equipment meets the standardization requirements, so that the system is consistent and predictable when used in different occasions. The measurement data acquisition and processing unit is used to improve the overall efficiency and response speed of the system. The data acquisition liquid level analysis unit combines three different analysis methods to conduct in-depth analysis of the target acquisition data from multiple angles, so as to more comprehensively understand the characteristics and trends of liquid level changes.

The real-time monitoring and early warning unit can adapt to liquid level adjustment needs of different scales and complexities through adjustment data. The data transmission and display unit reduces the labor intensity of staff and improves work efficiency.

[0113] The measuring device is equipped with a detection unit and is also used for:

[0114] The liquid measuring devices in the clean room include liquid level sensors, liquid flow meters, temperature sensors, pressure sensors, liquid property sensors and liquid pumps;

[0115] Conduct equipment testing on the liquid level sensor, liquid flow meter, temperature sensor, pressure sensor, liquid property sensor and liquid pump respectively;

[0116] Among them, the liquid level sensor is subjected to functional testing, calibration testing and anti-interference ability testing; the liquid flow meter is subjected to flow calibration, flow range testing and response time testing; the temperature sensor is subjected to calibration testing, measurement range testing and thermal response testing; the pressure sensor is subjected to calibration testing, pressure range testing and pressure resistance testing; the liquid property sensor is subjected to calibration testing, response time testing and stability testing; the liquid pump is subjected to performance evaluation, flow stability testing and overload protection testing;

[0120] The measurement data acquisition and processing unit is also used for:

[0121] The standard measuring device continuously monitors the height of the liquid level in the clean room through physical principles and converts the height of the liquid level into an electrical signal;

[0122] The sensor converts the electrical signal into a digital signal, and performs filtering, smoothing and correction processing on the converted digital signal;

[0123] After filtering, smoothing and correcting the digital signal, the liquid level value of the scale is obtained;

[0124] The readable liquid level value is subjected to data preprocessing again;

[0125] Data preprocessing includes data validation, data cleaning, data standardization, and data compression;

[0126] After data preprocessing, the target acquisition data is obtained.

[0127] Specifically, the accuracy and reliability of liquid level measurement are improved through monitoring based on physical principles by standard measuring devices and multi-level signal processing (filtering, smoothing and correction) of sensors. Signal filtering and smoothing can remove noise and short-term fluctuations, making liquid level measurement more stable and reducing the possibility of errors and false alarms.

These steps can remove outliers, unify data formats, reduce redundant data, and improve data availability and efficiency. Data standardization makes processed data easier to connect with other systems or modules, improving system compatibility and data consistency. Data compression reduces data storage space requirements and transmission bandwidth requirements, and improves the overall efficiency and response speed of the system.

[0128] In order to solve the problem in the prior art that the collected measurement data is not analyzed more carefully and the analyzed data is not used for further liquid pump adjustment, which leads to the inability to accurately adjust the operating speed, please refer to Figure 1 and Figure 2 , this embodiment provides the following technical solutions:

[0129] The data acquisition liquid level analysis unit is also used for:

[0130] The target collected data is analyzed using different data analysis methods, such as trend analysis, statistical analysis and time series analysis;

[0131] Among them, the trend analysis method is to judge the change trend of the target collected data through linear regression, moving average and exponential smoothing, and the change trend includes rising, falling or stable;

[0132] The statistical analysis method is to collect statistics on the mean, standard deviation, maximum and minimum values ​​of the target collected data and evaluate the level fluctuation changes;

[0133] The time series analysis method uses the time series model in the database to predict the level change trend of the target collected data;

[0134] The liquid level trend data of the trend analysis method, statistical analysis method and time series analysis method are extracted respectively;

[0135] The extracted different liquid level trend data are concentrated into the same data set, and the time lines of the different liquid level trend data are aligned. After the time lines are aligned, the weights of the different liquid level trend data are allocated;

[0136] The different liquid level trend data after weight distribution are fused to obtain the liquid level trend change data.

[0137] Specifically, by combining three different analysis methods, the target data can be analyzed in depth from multiple angles, so as to more comprehensively understand the characteristics and trends of liquid level changes. The trend analysis method can accurately determine the change trend of liquid level through linear regression, moving average and exponential smoothing techniques. Statistical analysis provides statistical quantities such as the mean, standard deviation, maximum and minimum values ​​of the data, which helps to evaluate the degree of liquid level fluctuation. Time series analysis uses historical data to build a model to predict the future trend of liquid level changes, which increases the reliability of the analysis. The liquid level trend data obtained by different analysis methods are concentrated into the same data set, and the timeline is aligned to ensure the consistency and comparability of the data. Through weight allocation, different data sources can be weighted according to the accuracy and importance of different analysis methods, which further improves the accuracy of the results. Data fusion technology can integrate data from different sources and formats to form a more comprehensive and accurate data set. The liquid level trend change data after data fusion can more accurately reflect the actual situation and provide a more reliable basis for decision-making.

[0138] Analytical data liquid conditioning unit, also used for:

[0139] Performing liquid level safety analysis on the liquid level trend change data according to the safety liquid level rules, wherein the safety liquid level rules are extracted from the database and include the highest safety liquid level, the lowest safety liquid level and the alarm liquid level;

[0140] Liquid level safety analysis is to analyze the abnormal change pattern of liquid level in the liquid level trend change data. The abnormal change pattern of liquid level is that the frequency of liquid level rising or falling in a short period of time exceeds the preset value;

[0141] According to the results of the liquid level safety analysis, the liquid level trend change data is subject to risk assessment, and the risk assessment is divided into low risk, medium risk and high risk;

[0142] Prioritize different risk assessments and formulate adjustment parameters for the risk assessment results in each priority level;

[0143] The regulation parameters are formulated to adjust the operating speed of the liquid pump and control the liquid level by increasing or decreasing the inflow or outflow rate of the liquid;

[0144] After the adjustment parameters are formulated, the liquid level data to be adjusted is obtained.

[0145] Specifically, the safe liquid level rules are extracted from the database, which means that the rules can be dynamically updated according to the actual situation, so that the system can adapt to different working environments and safety requirements. By analyzing the abnormal change patterns in the liquid level trend change data (such as the frequency of the liquid level rising or falling in a short period of time exceeds the preset value), the system can promptly discover potential liquid level safety problems and trigger corresponding alarms or preventive measures. The liquid level trend change data is risk assessed and divided into low risk, medium risk and high risk, which helps managers to understand the current liquid level status more intuitively, so as to make more accurate decisions, prioritize different risk assessment results, and ensure that high-risk issues are dealt with first. The system first solves high-risk problems and then deals with medium- and low-risk problems, which improves the efficiency and effectiveness of problem handling. According to the risk assessment results, adjustment parameters are formulated to adjust the operating speed of the liquid pump. The liquid level is controlled by increasing or decreasing the inflow or outflow rate of the liquid. This method is both scientific and practical, and can ensure that the liquid level fluctuates within a safe range. From data extraction and analysis to parameter formulation, automated operations can be achieved, reducing the complexity and uncertainty of manual intervention and improving the stability and reliability of the system. Through real-time monitoring and early warning, as well as scientific formulation of adjustment parameters, this solution can significantly improve the safety and efficiency of liquid level control and reduce potential risks and losses caused by abnormal liquid levels.

[0146] In order to solve the problem in the prior art that there is no continuous monitoring of the liquid pump adjustment process, and no effective data display and warning of the parameter data during the adjustment process, which results in the staff being unable to obtain the liquid level adjustment status in time, please refer to Figure 1 and Figure 2 , this embodiment provides the following technical solutions:

[0147] The real-time monitoring and early warning unit of the adjustment data is also used for:

[0148] Reading the liquid level data to be adjusted, the liquid level data to be adjusted includes the current liquid level state, the target liquid level and the adjustment amount of the liquid level pump;

[0149] Generate a liquid pump adjustment instruction based on the liquid level data to be adjusted, and the liquid pump adjustment instruction is to determine whether the current liquid level is higher, lower or close to a set safety threshold;

[0150] If the current liquid level is lower than the minimum safe liquid level, adjust the liquid pump to increase the liquid inflow;

[0151] If the current liquid level is higher than the maximum safe liquid level, adjust the liquid pump to reduce liquid inflow or increase liquid outflow;

[0152] If the current liquid level is within the safe range but close to the boundary, the liquid pump is fine-tuned according to the specific situation;

[0153] Implement the instructions according to the liquid pump adjustment instructions, send the generated liquid pump adjustment instructions to the liquid pump through the controller, and after the liquid pump receives the instructions, perform corresponding operations to adjust the inflow or outflow of liquid;

[0154] When the liquid pump executes the adjustment instruction, the change of the liquid level is continuously monitored, and the continuously monitored liquid level data is marked as feedback monitoring data;

[0155] Generate an alarm plan based on the difference between the feedback monitoring data and the liquid pump adjustment instruction;

[0156] The larger the difference, the greater the alarm intensity, and the generated alarm scheme is marked as abnormal liquid level data.

[0157] Specifically, by reading the liquid level data to be adjusted, the liquid pump adjustment instructions are automatically generated, which reduces manual intervention and improves the automation of the system. The system can intelligently judge and adjust the operation of the liquid pump according to the relationship between the current liquid level and the target liquid level to achieve precise control of the liquid level. By real-time monitoring of liquid level changes and rapid response, the system can efficiently adjust the working state of the liquid pump to ensure that the liquid level is always kept within a safe range. Automated adjustment reduces the possibility of human error, improves the accuracy of liquid level control, sets the minimum and maximum safe liquid level thresholds, and when the liquid level deviates from the safe range, the system can quickly take measures to prevent the potential safety hazards caused by excessively high or low liquid levels. Through continuous monitoring and feedback mechanisms, the system can promptly detect and handle abnormal situations, improve the reliability of the system, and both the generation of liquid pump adjustment instructions and alarm schemes have certain flexibility and can be fine-tuned according to specific circumstances. The system is easy to expand and can adapt to liquid level adjustment needs of different scales and complexities. When the difference between the liquid level data and the liquid pump adjustment instructions is large, the system can generate an alarm scheme and mark it as abnormal liquid level data, so that relevant personnel can respond quickly and take measures.
