Description

Technical Field

[0001] The invention belongs to the technical field of sensors, and in particular relates to a dual-system automatic drainage intelligent pressure difference sensor and a drainage method and system thereof. Background Art

[0002] With the continuous improvement of industrial automation, water supply and drainage systems in various industrial production processes and civil facilities have become increasingly complex and sophisticated. In these systems, accurate monitoring and control of pressure differences and timely and efficient drainage operations are essential to ensure stable system operation, prevent equipment damage, and ensure production safety and product quality. As a key pressure monitoring device, the performance and function of the differential pressure sensor directly affect the reliability of the entire system.

[0003] In traditional drainage systems, single-system drainage is dominant. This method has many obvious shortcomings when facing complex and changeable working conditions. For example, when the system encounters a sudden surge in flow or abnormal pressure, the single-system drainage is often unable to effectively and timely remove the accumulated water due to limited processing capacity, resulting in pressure imbalance in the system, which in turn causes equipment failures such as pipe rupture and pump damage, seriously affecting production progress and causing huge economic losses. At the same time, the single-system drainage lacks an effective intelligent adjustment mechanism, making it difficult to adjust the drainage strategy in real time according to actual working conditions, resulting in low drainage efficiency and excessive energy consumption.

[0004] Some existing differential pressure sensors have a single function in drainage control and can only provide simple differential pressure monitoring data. They are unable to achieve deep integration with the drainage system to perform intelligent drainage operations. This results in the need for frequent manual intervention in the drainage process based on differential pressure data in actual applications, which not only increases labor costs and the risk of human error, but also makes it difficult to achieve accurate and efficient drainage control. In addition, some so-called "intelligent" differential pressure sensors have a low degree of intelligence and are unable to accurately judge drainage needs when faced with complex working conditions, often resulting in over-drainage or under-drainage, which not only wastes water resources but also fails to ensure the normal operation of the system.

[0005] In summary, the current drainage system and differential pressure sensor have many limitations in function and performance, which makes it difficult to meet the urgent needs of modern industrial and civil fields for efficient, intelligent and stable drainage. Therefore, the development of an intelligent differential pressure sensor with dual-system automatic drainage function and its supporting drainage method and system has important practical significance for improving the intelligence level of the drainage system, ensuring the stable operation of the system, reducing energy consumption and reducing water waste. Summary of the invention

[0023] See also Figure 1 , which is a schematic diagram of the three-dimensional structure of the dual-system automatic drainage intelligent differential pressure sensor proposed in the present invention, including a differential pressure sensor body 1, on which a positioning chassis 14 is provided. The positioning chassis 14 is made of high-strength engineering plastic material, which not only has good insulation performance and can effectively prevent sensor measurement errors caused by electrical interference, but also has excellent impact resistance.

The water inlet pipe 12 is made of a special rubber material that is resistant to high pressure and corrosion, can withstand high water pressure, and is not easily corroded by chemical substances in the water flow, effectively ensuring the stable transmission of the water flow.

[0024] See also Figure 2, is a schematic cross-sectional view of the height adjustment mechanism structure proposed in an embodiment of the present invention, the height adjustment mechanism 2 includes a connecting member 21, the connecting member 21 is fixedly connected to the differential pressure sensor body 1, the connecting member 21 is fixedly provided with a first ring 22 and a second ring 23, the positioning chassis 14 is rotatably inserted with an adjusting screw 24, the positioning chassis 14 is fixedly provided with a guide rod 25, the first ring 22 is used in conjunction with the guide rod 25, the second ring 23 is used in conjunction with the adjusting screw 24, the end of the adjusting screw 24 away from the positioning chassis 14 is fixedly provided with a turntable 26, the positioning chassis 14 is provided with a mounting hole 15, the end of the adjusting screw 24 away from the positioning chassis 14 is fixedly provided with a turntable 26, the turntable 26 adopts an ergonomic design, and the surface is provided with an anti-slip texture, which increases the friction between the operator's hand and the turntable, and is convenient for the operator to apply force to rotate.

[0025] See also Figure 3 , is a schematic cross-sectional view of a water inlet pipe mechanism according to an embodiment of the present invention. An impurity filter cartridge 16 is provided inside the water inlet pipe 12, and the impurity filter cartridge 16 is made of stainless steel.

[0026] The working principle and use process of a dual-system automatic drainage intelligent differential pressure sensor of the present invention are as follows: first, the differential pressure sensor body 1 is firmly installed at the designated position of the pipeline or equipment where the pressure difference needs to be monitored through the mounting hole 15 on the positioning chassis 14, using matching bolts or other fixings. During the installation process, the height of the differential pressure sensor body 1 can be accurately adjusted by the height adjustment mechanism 2 according to actual needs, and the turntable 26 is rotated, and the turntable drives the adjusting screw rod 24 to rotate. Since the second ring 23 is matched with the adjusting screw rod 24, when the screw rod rotates, the second ring 23 will move up and down along the screw rod, thereby driving the connecting piece 21 connected thereto and the differential pressure sensor body 1 fixed on the connecting piece 21 to move synchronously. At the same time, the first ring 22 slides on the guide rod 25 to ensure that the differential pressure sensor body 1 always keeps moving in the vertical direction to avoid deviation.

[0027] When the system starts running, water flows into the differential pressure sensor body 1 through the water inlet pipe 12. The impurity filter cartridge 16 inside the water inlet pipe 12 will filter the impurities in the water flow to prevent the impurities from entering the sensor and affecting the measurement accuracy and damaging the equipment. At this time, the differential pressure sensor body 1 starts to monitor the pressure difference at different positions in the pipeline in real time, and transmits the data to the built-in microprocessor. During the entire drainage process, the high-definition display screen 11 will display the current pressure difference value, the operating status of the drainage system (such as whether the main drainage system is working, whether the auxiliary drainage system is started, etc.) and other key information in real time, so that the operator can check and understand the system status at any time. When the system pressure difference returns to the normal preset range, the microprocessor will control the main drainage system and the auxiliary drainage system to stop working in turn and close the corresponding drainage valve. During the whole process, the differential pressure sensor body 1 continuously monitors the system status and prepares for the next possible drainage operation. This cycle is repeated to ensure that the system is always in a stable and efficient operating state.

[0028] See also Figure 4 As shown, a drainage method of a dual-system automatic drainage intelligent pressure difference sensor proposed in one embodiment of the present invention includes: S1. Obtain the pressure differential sensor body to be processed, collect the real-time pressure differential data and historical drainage operation log of the pressure differential sensor body, set the drainage parameters of the pressure differential sensor body in combination with the real-time pressure differential data and the historical drainage operation log, and obtain the dynamic drainage parameter configuration of the pressure differential sensor body.

[0029] The present invention processes the pressure differential sensor body in combination with the real-time pressure differential data and the historical drainage operation log, thereby being able to accurately grasp the drainage requirements of the sensor under different working conditions, providing a strong basis for setting reasonable drainage parameters, and ensuring efficient and stable operation of the drainage system. At the same time, it avoids problems such as poor drainage or excessive drainage due to inappropriate parameters, thereby improving the overall performance and reliability of the system.

[0030] Among them, the real-time pressure difference data is instant data reflecting the changes in the pressure difference value monitored by the pressure difference sensor at the current moment; the historical drainage operation log covers the time, frequency, duration of each drainage, and the operating conditions information at the time (such as ambient temperature, humidity, system operating status, etc.) of the drainage operations performed on the pressure difference sensor in the past.

[0031] As an embodiment of the present invention, the method of combining the real-time pressure difference data and the historical drainage operation log to set drainage parameters for the pressure difference sensor body to obtain a dynamic drainage parameter configuration of the pressure difference sensor body includes: Analyze the fluctuation trend of the real-time pressure difference data, and evaluate the drainage frequency factor of the pressure difference sensor body under different working conditions according to the historical drainage operation log; Based on the fluctuation trend, determining a potential drainage risk level of the differential pressure sensor body under a current working condition; Analyze the drainage effect difference pattern corresponding to the drainage frequency factor; Classify and label the current working condition of the differential pressure sensor body according to the potential drainage risk level and the drainage effect difference mode to obtain a labeled working condition category; Formulate drainage parameter strategies corresponding to the marked working condition categories;

[0032] Based on the drainage parameter strategy, drainage parameters are set for the differential pressure sensor body to obtain a dynamic drainage parameter configuration of the differential pressure sensor body.

[0033] Among them, the fluctuation trend is the rising, falling or stable change trend of the real-time pressure difference data over time; the drainage frequency factor is a quantitative indicator reflecting the frequency of drainage operations under different working conditions based on the historical drainage operation log; the potential drainage risk level is the risk level classification of poor drainage or other drainage-related problems that may occur under the current working conditions based on the fluctuation of real-time pressure difference data; the drainage effect difference mode is the different impact mode of drainage operation on system performance (such as pressure stability, drainage efficiency, etc.) under different drainage frequencies; the marked working condition category is a classification of the current working condition with risk and effect feature identification based on the potential drainage risk level and drainage effect difference mode; the drainage parameter strategy is a setting scheme for parameters such as drainage start pressure threshold, drainage duration, drainage frequency, etc., which is formulated for the risk characteristics and drainage effect requirements of the marked working condition category.

[0034] Optionally, the fluctuation trend of the real-time differential pressure data can be analyzed by a time series analysis algorithm, and the drainage frequency factor of the differential pressure sensor body under different working conditions can be evaluated by constructing a working condition and drainage operation association model based on the historical drainage operation log; based on the fluctuation trend, the potential drainage risk level of the differential pressure sensor body under the current working condition can be determined by studying the relationship between the pressure difference and drainage; based on the drainage frequency factor, the drainage effect difference pattern corresponding to different drainage frequency levels is analyzed with the help of experimental data and experience summary; according to the potential drainage risk level and the drainage effect difference pattern, the current working condition is classified and labeled according to pre-set classification rules to obtain the labeled working condition category; according to the characteristics of the labeled working condition category, a drainage parameter strategy corresponding to the labeled working condition category is formulated, and based on the drainage parameter strategy, the drainage parameters of the differential pressure sensor body are set to obtain the dynamic drainage parameter configuration of the differential pressure sensor body, such as appropriately reducing the drainage start pressure threshold and extending the drainage duration for working conditions with high risks and poor drainage effects.

[0035] S2. Connect the pressure difference sensor body to the dual-system drainage device, and based on the dynamic drainage parameter configuration, use the preset driving dual systems to alternately perform the drainage operation of the dual-system drainage device, and monitor the fluid state of the water inlet pipe of the pressure difference sensor body in real time.

[0036] The present invention connects the pressure difference sensor body to the dual-system drainage device, and drives the dual systems to work alternately according to the dynamic drainage parameter configuration, so as to realize an efficient, accurate and stable drainage process, monitor the fluid state of the water inlet pipe in real time, and help to promptly discover abnormal situations and adjust the drainage strategy to ensure the reliable operation of the entire system. It should be explained that the dual-system drainage device is composed of a main drainage system and an auxiliary drainage system, and the working mode can be flexibly switched according to different working conditions.

[0037] As an embodiment of the present invention, the specific operation process is as follows: Accurately connect the differential pressure sensor body to the designated interface of the dual-system drainage device to ensure a tight and stable connection, guarantee smooth data transmission and water flow, and start the preset driver program based on the key parameters such as the drainage start pressure threshold and drainage frequency in the dynamic drainage parameter configuration. The driver program intelligently controls the main drainage system and the auxiliary drainage system in the dual-system drainage device to alternately perform drainage operations according to the set logic. For example, when the water inlet pipe pressure reaches the drainage start pressure threshold, the main drainage system starts first to perform drainage operations; after the main drainage system has been running for a period of time, if the pressure has not returned to the normal range, the auxiliary drainage system will automatically start and work with the main drainage system to enhance the drainage effect.

[0038] During the drainage operation, high-precision flow sensors and pressure sensors are used to monitor the fluid state of the water inlet pipe of the differential pressure sensor body in real time. These sensors can continuously collect data such as the flow rate, pressure and temperature of the water flow in the water inlet pipe, and transmit the data to the system control center in real time. The control center analyzes the collected data in real time to determine whether the fluid in the water inlet pipe is in a normal state. If the fluid state is abnormal, such as sudden changes in flow, too high or too low pressure, the system will immediately issue an alarm and automatically adjust the drainage parameters of the dual system drainage device according to the preset emergency plan, such as increasing the drainage flow, extending the drainage time, etc., to ensure the stable operation of the system.

[0039] S3. Synchronously collect the flow fluctuation curve and pressure gradient change data during the drainage process, calculate the water resistance coefficient and energy loss characteristics of the current drainage stage by combining the flow fluctuation curve and the pressure gradient change data, and calculate the real-time performance deviation of the differential pressure sensor body based on the water resistance coefficient and the energy loss characteristics.

[0040] The present invention analyzes the dynamic operation characteristics of the drainage system by synchronously collecting flow fluctuation curves and pressure gradient change data, and further quantifies the coupling effect of water resistance and energy loss, providing multi-dimensional parameter support for real-time performance evaluation, wherein the flow fluctuation curve is time series data reflecting the change of instantaneous flow in the pipeline over time, including flow velocity, periodic pulsation and abnormal fluctuation information; the pressure gradient change data is a dynamic representation of the pressure distribution difference along the axial direction of the pipeline, reflecting the comprehensive effect of fluid friction resistance and local resistance; further, the flow fluctuation curve can be captured in real time by an ultrasonic flowmeter, and the pressure gradient change data is synchronously collected by a distributed pressure sensor array.

[0041] As an embodiment of the present invention, the calculation of the water resistance coefficient and energy loss characteristics of the current drainage stage of the differential pressure sensor body in combination with the flow fluctuation curve and the pressure gradient change data includes: Performing time domain alignment on the flow fluctuation curve and the pressure gradient change data respectively to obtain a target flow fluctuation curve and a target pressure gradient data; Extracting the flow measurement value of the differential pressure sensor body from the target flow fluctuation curve, and averaging the flow measurement value to obtain an instantaneous flow mean value; Calculating a pressure gradient value of the differential pressure sensor body based on the target pressure gradient data; Calculate the hydraulic resistance coefficient of the differential pressure sensor body at the current drainage stage by combining the instantaneous flow mean value and the pressure gradient value; Based on the pressure gradient value, an energy loss characteristic of the current drainage stage of the differential pressure sensor body is calculated.

[0042] Among them, the target flow fluctuation curve and the target pressure gradient data are the data obtained after removing the noise errors and abnormal interference in the flow fluctuation curve and the pressure gradient change data respectively; the flow measurement value is the specific numerical value of the flow measured by the pressure difference sensor body at a specific moment or time period in the target flow fluctuation curve; the instantaneous flow mean is the average value of the flow measurement value in a very short time interval, which is used to reflect the average level of the flow near this moment; further, the flow fluctuation curve and the pressure gradient change data can be aligned in time domain by wavelet transform algorithm respectively to obtain the target flow fluctuation curve and target pressure gradient data; the data sampling algorithm can be used The flow measurement value of the differential pressure sensor body is extracted from the target flow fluctuation curve, and the flow measurement value can be averaged by a sliding average algorithm to obtain an instantaneous flow mean; based on the target pressure gradient data, the pressure gradient value of the differential pressure sensor body is calculated using a pressure gradient calculation formula; based on the pressure gradient value, the energy loss characteristics of the current drainage stage of the differential pressure sensor body are calculated, such as by combining the Darcy-Weisbach formula with the pressure gradient value, pipeline parameters (pipe diameter, length, etc.) and fluid properties (density, viscosity, etc.), and using a numerical calculation algorithm, accurately calculating the energy loss rate caused by water flow resistance in the current drainage stage, the energy loss per unit pipe length and other characteristics.

[0043] Further, as an optional embodiment of the present invention, the hydraulic resistance coefficient of the differential pressure sensor body in the current drainage stage is calculated in combination with the instantaneous flow mean value and the pressure gradient value, including: querying the pipe diameter of the differential pressure sensor body at the current drainage stage, and measuring the fluid density of the differential pressure sensor body at the current drainage stage; In combination with the pipe diameter, the fluid density, the instantaneous flow mean value and the pressure gradient value, the water resistance coefficient of the differential pressure sensor body at the current drainage stage is calculated by the following formula: ; Among them, A represents the water resistance coefficient of the differential pressure sensor body at the current drainage stage, B represents the pipe diameter, represents the pressure gradient value, represents the fluid density, Indicates the instantaneous flow mean.

[0044] Furthermore, the pipe diameter of the current drainage stage of the differential pressure sensor body can be queried by querying the pipeline design document or database information, and the fluid density of the current drainage stage of the differential pressure sensor body can be measured by using professional measuring instruments such as a densitometer.

[0045] The present invention calculates the real-time performance deviation of the differential pressure sensor body based on the water resistance coefficient and the energy loss characteristics, so as to timely detect abnormal conditions in the operation of the drainage system, and provide a key basis for accurately adjusting system parameters and optimizing operation strategies, thereby effectively improving the overall operation efficiency and stability of the drainage system, and reducing energy consumption and maintenance costs. It should be explained that the real-time performance deviation is a quantitative indicator of the difference between the current actual drainage efficiency and the ideal efficiency of the differential pressure sensor body, which is used to intuitively reflect the deviation of the drainage system operation status from the optimal state.

[0046] As an embodiment of the present invention, the calculating the real-time performance deviation of the differential pressure sensor body based on the water resistance coefficient and the energy loss characteristic includes: The real-time performance deviation of the differential pressure sensor body can be calculated by the following formula: ; Where G represents the real-time performance deviation of the differential pressure sensor body. represents the water resistance coefficient, It represents the theoretical water resistance coefficient under ideal working conditions. Represents the energy loss characteristics, Represents the theoretical energy loss characteristics under ideal working conditions.

[0047] Furthermore, the theoretical water resistance coefficient and theoretical energy loss characteristics can be obtained by theoretical deduction based on the classical fluid mechanics equations, combined with the design specifications of the drainage system (such as pipe inner diameter, length, roughness, etc.), and considering the physical properties of the fluid (density, viscosity); they can also be obtained by conducting a large number of experimental tests on similar drainage systems operating under standard working conditions, collecting data and analyzing and summarizing them.

[0048] S4. Dynamically correct the pressure threshold boundary condition of the dual-system drainage device according to the efficiency deviation, iteratively optimize the pressure equalization parameters of the dual-system drainage device based on the pressure threshold boundary condition, and obtain the drainage solution of the pressure differential sensor body when the output value of the pressure differential sensor body is stabilized in a preset safety interval.

[0049] The present invention can effectively improve the system operation stability and drainage efficiency by making targeted adjustments to the dual-system drainage device according to the performance deviation, and ensure that the differential pressure sensor works in a safe and reliable environment. It should be explained that the performance deviation reflects the degree of difference between the actual operating state of the current drainage system and the ideal state; the pressure threshold boundary condition determines the pressure range for starting and stopping drainage of the dual-system drainage device; the pressure balance parameter controls the pressure distribution and collaborative working mode between the main and auxiliary drainage systems.

[0050] As an embodiment of the present invention, the specific processing process is as follows: Construct an association model between performance deviation and pressure threshold boundary conditions. By analyzing a large amount of historical data and system operation simulation results, determine the functional relationship between performance deviation and pressure threshold boundary conditions. For example, when the performance deviation is high, it indicates that the system may have problems such as poor drainage or excessive pressure fluctuations. At this time, according to the association model, the lower limit of the pressure threshold is appropriately lowered to prompt the drainage device to start drainage at a lower pressure. At the same time, the upper limit of the pressure threshold is increased to enhance the system's ability to cope with sudden high-pressure situations, thereby broadening the working pressure range of the drainage device and improving the system's adaptability.

[0051] Based on the dynamically corrected pressure threshold boundary conditions, the intelligent optimization algorithm is used to iteratively optimize the pressure equalization parameters of the dual-system drainage device. The particle swarm optimization algorithm is used, and the pressure threshold boundary conditions are used as constraints. The optimization objectives are system pressure stability, drainage flow uniformity, and energy consumption minimization. In the initialization stage of the algorithm, a set of initial values ​​of pressure equalization parameters are randomly generated, including the pressure switching difference between the main drainage system and the auxiliary drainage system, the pressure distribution ratio under different working conditions, etc. In each iteration, according to the rules of the particle swarm optimization algorithm, the fitness value of each parameter combination under the current pressure threshold boundary conditions is calculated, that is, the degree of satisfaction of the parameter combination with the optimization objective is evaluated. By continuously updating the position and velocity of the particles, a better combination of pressure equalization parameters is gradually searched. For example, under a certain working condition, after multiple iterations, it is found that when the pressure switching difference between the main and auxiliary drainage systems is XkPa and the pressure distribution ratio is Y, the system pressure stability is significantly improved, the drainage flow uniformity is good, and the energy consumption is reduced. This parameter combination is the optimal solution in the current iteration process.

[0052] In the process of iterative optimization of pressure equalization parameters, the output value of the differential pressure sensor body is monitored in real time. The preset safety interval is a reasonable pressure difference range determined according to the design requirements of the drainage system, the tolerance of the equipment and the actual operating experience. After multiple rounds of iterative optimization, the output value of the differential pressure sensor body is continuously and stably within the preset safety interval, indicating that the operating state of the dual-system drainage device has reached a relatively ideal level. The pressure threshold boundary conditions and pressure equalization parameters determined at this time are sorted and recorded to form a complete drainage plan for the differential pressure sensor body. This tuning plan can not only effectively improve the performance of the dual-system drainage device, but also ensure the long-term stable and accurate operation of the differential pressure sensor body, providing strong support for the efficient operation of the entire drainage system.
