Description

Technical Field

[0001] The present invention belongs to the technical field of sensors, and particularly relates to a dual-system automatic drainage intelligent differential pressure sensor, its drainage method and system. Background Art

[0002] With the continuous improvement of industrial automation, the water supply and drainage systems in various industrial production processes and civil facilities have become increasingly complex and sophisticated. In these systems, accurately monitoring and controlling the pressure difference and draining water in a timely and efficient manner are crucial for ensuring the stable operation of the system, preventing equipment damage, and ensuring 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, the single-system drainage method dominates. When facing complex and changeable working conditions, this method exposes many obvious deficiencies. For example, when the system encounters a sudden surge in flow or abnormal pressure, single-system drainage often fails to effectively drain the accumulated water in a timely manner due to limited processing capacity, resulting in pressure imbalance within the system, which in turn leads to equipment failures such as pipeline ruptures and pump body damage, seriously affecting the production progress and causing huge economic losses. At the same time, the single-system drainage lacks an effective intelligent adjustment mechanism and is difficult to adjust the drainage strategy in real time according to the actual working conditions, resulting in low drainage efficiency and high energy consumption.

[0004] Some existing differential pressure sensors have a single function in drainage control and can only provide simple pressure difference monitoring data. They cannot be deeply integrated with the drainage system for intelligent drainage operations. This leads to the need for manual intervention in the drainage process based on differential pressure data frequently in practical applications, which not only increases the labor cost 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 cannot accurately judge the drainage demand when facing complex working conditions, often resulting in over-drainage or under-drainage, wasting water resources and unable to ensure the normal operation of the system.

[0005] In summary, the current drainage systems and differential pressure sensors have many limitations in terms of function and performance, and it is difficult to meet the urgent needs of modern industrial and civil fields for efficient, intelligent, and stable drainage. Therefore, the research and development of an intelligent differential pressure sensor with dual-system automatic drainage function and its supporting drainage method and system have 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 resource waste. Summary of the Invention

[0006] The object of the present invention is to provide a dual - system automatic drainage intelligent differential pressure sensor to solve the problems of insufficient ability of the traditional single - system drainage method to cope with complex working conditions, and the single function and low intelligence level of the existing differential pressure sensors as proposed in the above - mentioned background technology.

[0009] The height - adjusting mechanism includes a connecting piece, which is fixedly connected to the differential pressure sensor body. A first collar and a second collar are fixedly arranged on the connecting piece. An adjusting screw rod is rotatably inserted on the positioning chassis, and a guide rod is fixedly installed on the positioning chassis. The first collar is used in cooperation with the guide rod, and the second collar is used in cooperation with the adjusting screw rod. A turntable is fixedly installed at one end of the adjusting screw rod away from the positioning chassis.

[0010] In a possible implementation manner of the first aspect, a high - definition display screen is arranged on the differential pressure sensor body.

[0011] In a possible implementation manner of the first aspect, a water inlet pipe is fixedly installed on the differential pressure sensor body, and a sealing nut is threadedly sleeved on the outer surface of the water inlet pipe.

At the same time, a sealing nut is threadedly sleeved on the outer surface of the water inlet pipe, which can enhance the sealing performance of the connection of the water inlet pipe, prevent water leakage, and further ensure the stable operation of the system. However, many differential pressure sensors in the prior art have deficiencies in anti-impurity and sealing, and are prone to affecting the sensor performance due to impurity and water leakage problems.

[0047] It can be seen that by combining the real-time differential pressure data and the historical drainage operation log to process the differential pressure sensor body, the present invention can accurately grasp the drainage requirements of the sensor under different working conditions, provide a strong basis for setting reasonable drainage parameters, ensure the efficient and stable operation of the drainage system, and at the same time avoid problems such as poor drainage or excessive drainage caused by improper parameters, improving the overall performance and reliability of the system.

By synchronously collecting the flow fluctuation curve and the pressure gradient change data and analyzing the dynamic operation characteristics of the drainage system, the present invention can further quantify the coupling effect of water resistance and energy loss, providing multi-dimensional parameter support for real-time performance evaluation. By making targeted adjustments to the dual-system drainage device according to the efficiency deviation degree, the present invention can effectively improve the operation stability and drainage efficiency of the system and ensure that the differential pressure sensor works in a safe and reliable environment.

[0057] Please refer to Figure 2 , which is a cross-sectional schematic diagram of the structure of the height adjustment mechanism proposed in an embodiment of the present invention. The height adjustment mechanism 2 includes a connecting piece 21, and the connecting piece 21 is fixedly connected to the differential pressure sensor body 1. A first collar 22 and a second collar 23 are fixedly provided on the connecting piece 21. An adjustment screw rod 24 is rotatably inserted on the positioning chassis 14. A guide rod 25 is fixedly installed on the positioning chassis 14. The first collar 22 is used in cooperation with the guide rod 25, and the second collar 23 is used in cooperation with the adjustment screw rod 24. A turntable 26 is fixedly installed at one end of the adjustment screw rod 24 away from the positioning chassis 14. An installation hole 15 is provided on the positioning chassis 14. A turntable 26 is fixedly installed at one end of the adjustment screw rod 24 away from the positioning chassis 14. The turntable 26 is designed according to ergonomics, and anti-slip textures are provided on the surface, increasing the friction between the operator's hand and the turntable, facilitating the operator to apply force to rotate.

[0058] Please refer to Figure 3 , which is a cross-sectional schematic diagram of the water inlet pipe mechanism proposed in an embodiment of the present invention. An impurity filter cylinder 16 is provided inside the water inlet pipe 12, and the impurity filter cylinder 16 is made of stainless steel material.

[0059] Working principle and usage process of a dual - system automatic - drainage intelligent differential - pressure sensor of the present invention: First, the differential - pressure sensor body 1 is firmly installed at the designated position of the pipeline or equipment that needs to monitor the pressure difference through the mounting holes 15 on the positioning chassis 14 using the supporting bolts or other fixing parts. During the installation process, according to actual requirements, the height of the differential - pressure sensor body 1 can be precisely adjusted through the height - adjusting mechanism 2. Rotate the turntable 26, and the turntable drives the adjusting screw rod 24 to rotate. Since the second collar 23 is paired with the adjusting screw rod 24, when the screw rod rotates, the second collar 23 will move up and down along the screw rod, thereby driving the connected connecting piece 21 and the differential - pressure sensor body 1 fixed on the connecting piece 21 to move synchronously. At the same time, the first collar 22 slides on the guide rod 25 to ensure that the differential - pressure sensor body 1 always moves in the vertical direction and avoids deviation.

[0060] When the system starts to operate, water flows into the differential - pressure sensor body 1 through the water inlet pipe 12. The impurity filter cylinder 16 inside the water inlet pipe 12 filters the impurities in the water flow to prevent 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 continuously monitor the pressure difference at different positions in the pipeline and transmits the data to the built - in micro - processor. 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, which is convenient for the operator to view and understand the system situation at any time. When the system pressure difference returns to the normal preset range, the micro - processor will control the main drainage system and the auxiliary drainage system to stop working in sequence and close the corresponding drainage valves. During the whole process, the differential - pressure sensor body 1 continuously monitors the system status to prepare for the next possible drainage operation, and so on in a cycle to ensure that the system is always in a stable and efficient operating state.

[0061] Refer to Figure 4 As shown in the figure, a drainage method of the dual - system automatic - drainage intelligent differential - pressure sensor proposed in an embodiment of the present invention includes:

[0062] S1. Obtain the differential - pressure sensor body to be processed, collect the real - time differential - pressure data and historical drainage operation logs of the differential - pressure sensor body, and combine the real - time differential - pressure data and the historical drainage operation logs to set the drainage parameters for the differential - pressure sensor body to obtain the dynamic drainage parameter configuration of the differential - pressure sensor body.

[0063] By processing the differential pressure sensor body by combining the real-time differential pressure data and the historical drainage operation log, the present invention can accurately grasp the drainage requirements of the sensor under different working conditions, provide a strong basis for setting reasonable drainage parameters, ensure the efficient and stable operation of the drainage system, and at the same time avoid problems such as poor drainage or excessive drainage caused by improper parameters, improving the overall performance and reliability of the system.

[0064] Among them, the real-time differential pressure data is instant data reflecting the change of the pressure difference monitored by the differential pressure sensor at the current moment; the historical drainage operation log covers records of the time, frequency, duration of each drainage operation on the differential pressure sensor in the past, and the working condition information at that time (such as ambient temperature, humidity, system operation status, etc.).

[0065] As an embodiment of the present invention, by combining the real-time differential pressure data and the historical drainage operation log, drainage parameters are set for the differential pressure sensor body to obtain the dynamic drainage parameter configuration of the differential pressure sensor body, including:

[0066] Analyze the fluctuation trend of the real-time differential pressure data, and evaluate the drainage frequency factor of the differential pressure sensor body under different working conditions according to the historical drainage operation log;

[0067] Based on the fluctuation trend, determine the potential drainage risk level of the differential pressure sensor body under the current working condition;

[0068] Analyze the drainage effect difference mode corresponding to the drainage frequency factor;

[0069] According to the potential drainage risk level and the drainage effect difference mode, classify and label the current working condition of the differential pressure sensor body to obtain the labeled working condition category;

[0070] Formulate a drainage parameter strategy corresponding to the labeled working condition category;

[0071] Based on the drainage parameter strategy, set the drainage parameters for the differential pressure sensor body to obtain the dynamic drainage parameter configuration of the differential pressure sensor body.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] As an embodiment of the present invention, the specific operation process is as follows:

[0077] Accurately connect the differential pressure sensor body to the designated interface of the dual-system drainage device, ensuring a tight and stable connection to guarantee the smoothness of data transmission and the water flow path. Based on the key parameters such as the drainage start pressure threshold and drainage frequency in the dynamic drainage parameter configuration, start the preset driver program. This driver program intelligently controls the main drainage system and the auxiliary drainage system in the dual-system drainage device to alternately carry out drainage operations according to the set logic. For example, when the pressure in the inlet pipe reaches the drainage start pressure threshold, the main drainage system starts first to carry out drainage operations; after the main drainage system has been operating for a period of time, if the pressure does not return to the normal range, the auxiliary drainage system will automatically start immediately and work together with the main drainage system to enhance the drainage effect.

[0078] During the execution of the drainage operation, use high-precision flow sensors and pressure sensors to continuously monitor the fluid state of the inlet pipe of the differential pressure sensor body. These sensors can continuously collect data such as the flow rate, pressure, and temperature of the water flow in the 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 inlet pipe is in a normal state. If it is found that the fluid state is abnormal, such as sudden changes in flow rate, too high or too low pressure, etc., 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 rate, extending the drainage time, etc., to ensure the stable operation of the system.

[0079] S3. Synchronously collect the flow fluctuation curve and the pressure gradient change data during the drainage process. Combine the flow fluctuation curve and the pressure gradient change data to calculate the water resistance coefficient and the energy loss characteristics of the current drainage stage. Based on the water resistance coefficient and the energy loss characteristics, calculate the real-time efficiency deviation degree of the differential pressure sensor body.

[0080] The present invention synchronously collects the flow fluctuation curve and the pressure gradient change data, analyzes the dynamic operation characteristics of the drainage system, and further quantifies the coupling effect of water resistance and energy loss, providing multi-dimensional parameter support for real-time efficiency evaluation. Among them, the flow fluctuation curve is time-series data reflecting the instantaneous flow rate in the pipeline over time, including information such as flow velocity, periodic pulsation, and abnormal fluctuations; the pressure gradient change data is a dynamic characterization of the difference in pressure distribution along the axial direction of the pipeline, reflecting the combined effect of fluid frictional 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.

[0081] As an embodiment of the present invention, calculating the water resistance coefficient and energy loss characteristics of the current drainage stage of the differential pressure sensor body by combining the flow fluctuation curve and the pressure gradient change data includes:

[0082] Perform time-domain alignment on the flow fluctuation curve and the pressure gradient change data respectively to obtain a target flow fluctuation curve and target pressure gradient data;

[0083] Extract the flow measurement value of the differential pressure sensor body from the target flow fluctuation curve, and perform an averaging process on the flow measurement value to obtain an instantaneous flow mean value;

[0084] Based on the target pressure gradient data, calculate the pressure gradient value of the differential pressure sensor body;

[0085] Combine the instantaneous flow mean value and the pressure gradient value to calculate the water resistance coefficient of the current drainage stage of the differential pressure sensor body;

[0086] Based on the pressure gradient value, calculate the energy loss characteristics of the current drainage stage of the differential pressure sensor body.

[0087] Among them, the target flow fluctuation curve and the target pressure gradient data are the data obtained after removing the noise error and abnormal interference in the flow fluctuation curve and the pressure gradient change data respectively; the flow measurement value is the specific value of the flow measured by the differential pressure sensor body in the target flow fluctuation curve at a specific moment or time period; the instantaneous flow mean value is the average value of the flow measurement value within a very short time interval, used to reflect the average level of the flow near that moment; further, the wavelet transform algorithm can be used to perform time-domain alignment on the flow fluctuation curve and the pressure gradient change data respectively to obtain a target flow fluctuation curve and target pressure gradient data; the data sampling algorithm can be used to extract the flow measurement value of the differential pressure sensor body from the target flow fluctuation curve, and the sliding average algorithm can be used to perform an averaging process on the flow measurement value to obtain an instantaneous flow mean value; based on the target pressure gradient data, the pressure gradient value of the differential pressure sensor body can be calculated using the 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 can be calculated, such as by combining the pressure gradient value, pipeline parameters (pipe diameter, length, etc.) and fluid properties (density, viscosity, etc.) through the Darcy-Weisbach formula, and using numerical calculation algorithms to accurately calculate the energy loss rate caused by water flow resistance and the energy loss per unit pipe length in the current drainage stage.

[0088] Further, as an alternative embodiment of the present invention, calculating the water resistance coefficient of the current drainage stage of the differential pressure sensor body based on the combination of the instantaneous flow mean value and the pressure gradient value includes:

[0089] Query the pipe diameter of the current drainage stage of the differential pressure sensor body, and measure the fluid density of the current drainage stage of the differential pressure sensor body;

[0090] Combining the pipe diameter, the fluid density, the instantaneous flow mean value and the pressure gradient value, calculate the water resistance coefficient of the current drainage stage of the differential pressure sensor body through the following formula:

[0091] ;

[0092] where A represents the water resistance coefficient of the current drainage stage of the differential pressure sensor body, B represents the pipe diameter, represents the pressure gradient value, represents the fluid density, represents the instantaneous flow mean value.

[0093] Further, the pipe diameter of the current drainage stage of the differential pressure sensor body can be queried by querying the pipe 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.

[0094] The present invention calculates the real-time efficiency deviation degree of the differential pressure sensor body based on the water resistance coefficient and the energy loss characteristics, can detect the abnormal conditions in the operation of the drainage system in time, provides a key basis for accurately adjusting the system parameters and optimizing the operation strategy, thereby effectively improving the overall operation efficiency and stability of the drainage system, reducing the energy consumption and maintenance cost. It should be noted that the real-time efficiency deviation degree is a quantitative index of the difference between the current actual efficiency and the ideal efficiency of the differential pressure sensor body, and is used to intuitively reflect the deviation of the operation status of the drainage system from the best state.

[0095] As an embodiment of the present invention, calculating the real-time efficiency deviation degree of the differential pressure sensor body based on the water resistance coefficient and the energy loss characteristics includes:

[0096] The real-time efficiency deviation degree of the differential pressure sensor body can be calculated through the following formula:

[0097] ;

[0098] where G represents the real-time efficiency deviation degree of the differential pressure sensor body, represents the water resistance coefficient, represents the theoretical water resistance coefficient under ideal working conditions, Represents the energy loss characteristic Represents the theoretical energy loss characteristic under ideal working conditions

[0099] Furthermore, the water resistance theoretical coefficient and the theoretical energy loss characteristic can be obtained through theoretical derivation by relying on classical fluid mechanics equations, combining 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); it 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

[0100] S4. Dynamically correct the pressure threshold boundary condition of the dual-system drainage device according to the effectiveness deviation degree, and iteratively optimize the pressure balance parameter of the dual-system drainage device based on the pressure threshold boundary condition. When the output value of the differential pressure sensor body is stable within a preset safe interval, obtain the drainage scheme of the differential pressure sensor body

[0101] By making targeted adjustments to the dual-system drainage device according to the effectiveness deviation degree, the present invention can effectively improve the system operation stability and drainage efficiency, and ensure that the differential pressure sensor works in a safe and reliable environment. It should be explained that the effectiveness deviation degree reflects the difference between the actual operation state and the ideal state of the current drainage system; the pressure threshold boundary condition determines the pressure range for the dual-system drainage device to start and stop draining; the pressure balance parameter controls the pressure distribution and collaborative working mode between the main and auxiliary drainage systems

[0102] As an embodiment of the present invention, the specific processing process is as follows

[0103] Construct an association model between the effectiveness deviation degree and the pressure threshold boundary condition. By analyzing a large amount of historical data and the system operation simulation results, determine the functional relationship between the effectiveness deviation degree and the pressure threshold boundary condition. For example, when the effectiveness deviation degree is relatively high, it indicates that there may be problems such as poor drainage or excessive pressure fluctuations in the system. At this time, according to the association model, appropriately lower the lower limit of the pressure threshold to prompt the drainage device to start draining at a lower pressure, and at the same time increase the upper limit of the pressure threshold 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 adaptability

[0104] Based on the dynamically corrected pressure threshold boundary conditions, an intelligent optimization algorithm is used to iteratively optimize the pressure balance parameters of the dual-system drainage device. The particle swarm optimization algorithm is adopted, with the pressure threshold boundary conditions as the constraint conditions, and the system pressure stability, drainage flow uniformity, and minimum energy consumption as the optimization objectives. In the initialization stage of the algorithm, a set of initial values of pressure balance parameters is 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 process, 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 to which the parameter combination meets the optimization objectives is evaluated. By continuously updating the positions and velocities of the particles, a better pressure balance parameter combination is gradually searched. For example, in a certain working condition, after multiple iterations, it is found that when the pressure switching difference between the main and auxiliary drainage systems is X kPa 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 better solution in the current iteration process.

[0105] During the process of iteratively optimizing the pressure balance 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 equipment tolerance, and the actual operation experience. When, after multiple rounds of iterative optimization, the output value of the differential pressure sensor body continuously and stably remains within the preset safety interval, it indicates that the operating state of the dual-system drainage device has reached an ideal level at this time. The determined pressure threshold boundary conditions and pressure balance parameters are sorted out and recorded to form a complete drainage plan for the differential pressure sensor body. This optimization 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.
