Description

Technical Field

[0001] The present invention relates to the technical field of secondary water supply control, and in particular to an intelligent secondary water supply terminal control system based on an AI algorithm. Background Art

[0002] Accurately understanding and controlling the static pressure of water supply is crucial to ensure that each floor has the appropriate water supply pressure. For example, in a high-rise residential building, too low static pressure may result in no water for high-rise users, while too high static pressure may damage pipes and water-using appliances. AI algorithms can process a large amount of data from sensors (such as pressure sensors, flow sensors, etc.); in the water supply system, by installing pressure sensors on the water supply pipes on different floors, static pressure data can be collected in real time.

[0003] The application with publication number CN116823521A discloses an intelligent secondary water supply terminal control system based on an AI algorithm, which includes a communication module, a scene prediction module, a water supply control module, a feedback calculation module, an adjustment module, and a sending module, which can be used to predict the water use scene based on the water supply working parameters sent by the secondary water supply terminal and the sensor data sent by the sensor device, and then determine the control instructions of the secondary water supply terminal according to the water use scene. It can be seen that the present invention can predict the water use scene based on the sensor parameters of the target water supply area, and then determine the water supply control instructions according to the water use scene to meet the needs of users, and can adjust the control according to user feedback, so as to achieve more intelligent and accurate and reasonable control of the secondary water supply terminal to improve the user's water supply experience.

[0004] In the secondary water supply treatment process, water is generally supplied uniformly based on the demand water supply pressure of the corresponding highest floor. Since the water supply pipes used are the same pipe, the water supply pressure of the lower floors is at the maximum state. However, in actual application, the water supply pressure can effectively make the water supply of the highest floor meet the standard. When the water supply pressure is appropriately reduced, the normal water use of the highest floor can be guaranteed simultaneously. Secondly, when the water supply pressure is appropriately reduced, the water supply pressure of the lower floors will also be reduced proportionally, and there is no problem with its water supply. The existing pressure supply method is to always use the maximum water supply pressure for water supply. Although this method can guarantee the normal water use of the corresponding floors, it will cause some energy waste. A proportional adjustment method is not adopted to enable each floor to not only effectively supply water but also save energy at the same time. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides an intelligent secondary water supply terminal control system based on AI algorithm, which solves the problem of not adopting a proportional adjustment method, so that each floor can not only effectively supply water but also save energy.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an intelligent secondary water supply terminal control system based on AI algorithm, comprising:

[0007] The associated water pressure confirmation terminal confirms the required water pressure associated with each group of control floors based on the control floors associated with the secondary water supply terminal, and transmits the different required water pressures confirmed for each floor to the control processing center. The confirmation methods include:

[0008] The number of the associated control floor is marked as C i , where i represents different control floors, using: C i ×Y1=G i Confirm the floor height associated with the corresponding control floor, where Y1 is the preset value;

[0009] Priority: P i = fluid density × g × G i Confirm the hydrostatic pressure P associated with the corresponding control floor i , where the fluid density is the density of water, which is 1000 kg / m 3 , where g is the acceleration due to gravity, which is 9.8 m / m 3 ;

[0010] Then use: Confirm the pipe loss parameter GS associated with the corresponding control floor i , where f is the preset friction coefficient, and L i is the pipe length, D is the pipe diameter, both are preset values. The pipe lengths corresponding to different control floors are different. g is the acceleration of gravity, v is the standard flow rate, and the hydrostatic pressure P confirmed on the corresponding control floor is i And the water pressure CY i To determine, its CY i =P i ×G i ×C1, where C1 is the preset fixed coefficient factor, using: Confirm the standard flow rate v;

[0011] Use: XQ i =P i +GS i + Equipment pressure confirmation corresponds to the required water pressure XQ of the control floor i , the pressure of the device is 0.1Mpa;

[0012] The real-time flow monitoring terminal monitors the water flow of the pipelines associated with each control floor in real time. When the flow value is detected, the real-time monitored flow value is directly transmitted to the control processing center;

[0013] The control processing center, based on the real-time monitored flow value of the corresponding control floor, locks the control floor that currently uses water, supplies pressure, and records the numerical performance and historical data of the corresponding flow value during the pressure supply process, and locks the normal floor and the abnormal floor. The specific method is as follows:

[0014] Based on the real-time monitored flow value, confirm the control floor where water is currently used and directly determine the floor height G i The highest control floor, determine the required water pressure XQ of this control floor i , control the pressure water pump to make the pressure value of the pressure water pump reach the required water pressure XQ i Supply pressure;

[0015] From the historical completion data, identify the control floors with water supply corresponding to the required water pressure XQ i The flow data generated under the water supply state is based on the minimum value V of its flow data i min and max values ​​V i max, confirm the flow interval [V i min-Y2,V i max+Y2], where Y2 is the preset value;

[0016] The real-time monitored flow value of the corresponding control floor is calibrated as LS i , where i represents different control floors, identifying the LS of the corresponding control floor i Satisfied: LS i ∈[V i min-Y2,V i max+Y2], if it is satisfied, the corresponding control floor is marked as a normal floor, if not, the corresponding control floor is marked as an abnormal floor;

[0017] If all floors are abnormal during the confirmation process, a water supply error signal will be directly generated for display;

[0018] The comprehensive control end controls the water pressure of multiple normal floors with water supply at the same time based on the calibrated normal floors, and adjusts the water supply pressure at the next moment in real time based on the demand water pressure and flow value at the previous moment. The specific method is as follows:

[0019] S1. Confirm the flow value LS corresponding to the normal floor at the current time i , and then directly confirm the middle value Z corresponding to the normal floor flow interval i , where the middle value is the mean between the minimum value and the maximum value of the interval, using CJ i =|LS i -Z i |Confirm the difference value CJ confirmed at the current momenti , and then determine the difference values ​​of other normal floors at the current moment in turn, and calculate the determined groups of difference values ​​CJ i Perform summation and confirm the total value;

[0020] S2. When the current moment ends and the next moment becomes the current moment, identify whether the normal floor associated with the current moment is consistent with the normal floor confirmed at the previous moment:

[0021] If they are consistent, then the confirmed demand water pressure XQ i Make adjustments, preferably downward, and identify whether the total value becomes smaller:

[0022] If it becomes smaller, continue to adjust in the subsequent moments until the total value reaches the minimum;

[0023] If it becomes larger, the required water pressure will be XQ i Adjust upwards, and continue to adjust in the subsequent moments until the total value drops to the minimum;

[0024] If the sum values ​​associated with the next moment and the next two moments are both increasing, then the current required water pressure XQ is maintained. i constant;

[0025] If they are not consistent, this moment is taken as the current moment and step S1 is executed again;

[0026] The cycle management center defines a set of monitoring cycles based on the marked abnormal floor, identifies the water flow curve of the abnormal floor within the monitoring cycle, and identifies whether there is a minimum water consumption line in the water flow curve. If there is a minimum water consumption line, a set of monitoring time periods is defined to identify whether there is a minimum water consumption line in other control floors located above the abnormal floor at the same time, and displays signals based on the identification results;

[0027] The specific method for determining the lowest water line of this abnormal floor is:

[0028] Based on the marked abnormal floors, a set of monitoring cycles is confirmed starting from the current moment, and the monitoring cycle is a preset cycle;

[0029] Based on the water flow monitored by the real-time flow monitoring terminal, confirm the water flow curve generated by the abnormal floor during this monitoring period;

[0030] The lowest water flow rate is identified from the water flow rate curve. If the lowest water flow rate = 0, it means that there is no lowest water line, and the abnormal floor is marked as a normal floor. If the lowest water flow rate ≠ 0, the line segment of the water flow rate curve that belongs to the lowest water flow rate is marked, and the marked line segment is marked as the lowest water line;

[0031] The specific method for identifying whether the lowest water use line exists synchronously in other control floors located at the height of this abnormal floor is as follows:

[0032] A set of monitoring time periods is defined, and the monitoring time period is a preset time period. Other control floors located above the abnormal floor are marked as floors to be monitored, and it is identified whether the other floors to be monitored also have a minimum water usage line during this monitoring period. The determination method is consistent with the abnormal floor in determining the water flow curve within a set of monitoring cycles, and the minimum water usage line is locked. If it exists, a pipeline inspection signal is generated. If not, a water use abnormality signal corresponding to the abnormal floor is generated.

[0033] The present invention provides an intelligent secondary water supply terminal control system based on AI algorithm. Compared with the prior art, it has the following beneficial effects:

[0034] The present invention not only considers the corresponding hydrostatic pressure, but also the corresponding head loss and the corresponding appliance demand pressure when determining the demand pressure of a specified floor, so that the confirmation accuracy of the demand pressure of the corresponding floor can be more accurate, and the water supply pressure of the corresponding floor can be fully satisfied, thereby achieving a better pressure accuracy guarantee effect;

[0035] In the subsequent water supply process, based on the water flow monitoring situation of the corresponding floor, it is identified whether the water flow of the corresponding floor is normal. For the relevant floors with normal flow, the water supply pressure is uniformly adjusted by comprehensive control, which can not only ensure the normal water use of each floor, but also effectively avoid energy loss and waste, achieving a better control and treatment effect;

[0036] For the confirmed abnormal floors, by confirming their lowest water usage line and the water usage of other floors, it is identified whether the corresponding abnormal floor has water usage abnormality or there is a water leakage abnormality in the corresponding water supply pipeline. The identification method is relatively comprehensive, which can not only carry out relevant control, but also achieve better abnormality identification effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] First embodiment

[0041] See also Figure 1 , the present application provides an intelligent secondary water supply terminal control system based on AI algorithm, including an associated water pressure confirmation terminal, a flow real-time monitoring terminal, a control processing center, a comprehensive control terminal and a cycle management center, wherein the associated water pressure confirmation terminal and the flow real-time monitoring terminal are both electrically connected to the input node of the control processing center, and the control processing center is electrically connected to the comprehensive control terminal and the cycle association center input node respectively, and the flow real-time monitoring terminal is electrically connected to the input node of the cycle management center;

[0042] Among them, the associated water pressure confirmation terminal confirms the demand water pressure associated with each group of control floors based on the control floors associated with the secondary water supply terminal, and transmits the different demand water pressures confirmed for each floor to the control processing center, wherein the demand water pressure confirmation method for each control floor includes:

[0043] Combination Figure 2 , the number of the associated control floor is marked as C i , where i represents different control floors, using: C i ×Y1=G i Confirm the floor height associated with the corresponding control floor, where Y1 is a preset value, generally 3m, and its specific value is determined by the operator based on the actual height of the corresponding floor;

[0044] Priority: P i = fluid density × g × G i Confirm the hydrostatic pressure P associated with the corresponding control floor i , where the fluid density is the density of water, which is 1000 kg / m 3 , where g is the acceleration due to gravity, which is 9.8 m / m 3 ;

[0045] Then use: Confirm the pipe loss parameter GS associated with the corresponding control floor i , the pipe loss parameter GS here is i is the head loss in MPa, where f is the preset friction coefficient, which is determined in advance by the relevant operators based on experience. i is the pipe length, D is the pipe diameter, which are automatically extracted from the system and are preset values. The pipe lengths corresponding to different control floors are different. g is the acceleration of gravity, v is the standard flow rate, and the hydrostatic pressure P confirmed based on the corresponding control floor i And the water pressure CY i To determine, its CY i =P i×G i ×C1, where C1 is the preset fixed coefficient factor, using: Confirm the standard flow rate v;

[0046] Use: XQ i =P i +GS i + Equipment pressure confirmation corresponds to the required water pressure XQ of the control floor i , the appliance pressure is 0.1Mpa, and the appliance pressure is the water demand pressure generated by the faucets, shower heads, toilets and other water-using appliances corresponding to each control floor;

[0047] When determining the demand pressure of a specified floor, not only the corresponding static water pressure is taken into account, but also the corresponding head loss and the corresponding appliance demand pressure. This can effectively make the confirmation accuracy of the demand pressure of the corresponding floor more accurate, and the water supply pressure of the corresponding floor can be fully met, achieving better pressure accuracy guarantee effect.

[0048] The real-time flow monitoring terminal monitors the water flow of the pipelines associated with each control floor in real time. When the flow value is detected, the real-time monitored flow value is directly transmitted to the control processing center using a designated flow sensor.

[0049] Among them, the control processing center, based on the flow value monitored in real time on the corresponding control floor, locks the control floor where water is currently used, supplies pressure, and records the numerical performance and historical data of the corresponding flow value during the pressure supply process, locks the normal floor and the abnormal floor, and the specific method of locking is:

[0050] Based on the real-time monitored flow value, confirm the control floor where water is currently used and directly determine the floor height G i The highest control floor, determine the required water pressure XQ of this control floor i , control the pressure water pump to make the pressure value of the pressure water pump reach the required water pressure XQ i Supply pressure;

[0051] From the historical completion data, identify the control floors with water supply corresponding to the required water pressure XQ i The flow data generated under the water supply state is based on the minimum value V of its flow data i min and max values ​​V i max, confirm the flow interval [V i min-Y2,V i max+Y2], where Y2 is a preset value, and its specific value is determined by the operator based on experience;

[0052] The real-time monitored flow value of the corresponding control floor is calibrated as LS i , where i represents different control floors, identifying the LS of the corresponding control floor i Satisfied: LS i ∈[V i min-Y2,V i max+Y2], if it is satisfied, the corresponding control floor is marked as a normal floor, if not, the corresponding control floor is marked as an abnormal floor;

[0053] If all floors are abnormal during the confirmation process (that is, there are no normal floors), a water supply error signal is directly generated for display, indicating that there is a problem with the corresponding pressure water pump.

[0054] Among them, the comprehensive control end controls the water pressure of multiple normal floors with water supply at the same time based on the calibrated normal floors, and adjusts the water supply pressure at the next moment in real time based on the demand water pressure and flow value at the previous moment, so that multiple normal floors can achieve better water supply effects. The specific methods of real-time adjustment are:

[0055] S1. Confirm the flow value LS corresponding to the normal floor at the current time i , and then directly confirm the middle value Z corresponding to the normal floor flow interval i , where the middle value is the mean between the minimum value and the maximum value of the interval (that is, a set of parameters in the middle), using CJ i =|LS i -Z i |Confirm the difference value CJ confirmed at the current moment i , and then determine the difference values ​​of other normal floors at the current moment in turn, and calculate the determined groups of difference values ​​CJ i Perform summation and confirm the total value;

[0056] S2. When the current moment ends and the next moment becomes the current moment, identify whether the normal floor associated with the current moment is consistent with the normal floor confirmed at the previous moment (that is, the normal floor corresponding to this moment has not changed):

[0057] If they are consistent, then the confirmed demand water pressure XQ i Make adjustments, preferably downward, and identify whether the total value becomes smaller:

[0058] If it becomes smaller, continue to adjust in the subsequent moments until the total value reaches the minimum;

[0059] If it becomes larger, the required water pressure will be XQ i Adjust upwards, and continue to adjust in the subsequent moments until the total value drops to the minimum;

[0060] If the sum values ​​associated with the next moment and the next two moments are both increasing (first, no matter whether the pressure value is adjusted upward or downward at the first moment, if the associated sum value increases, then the pressure value corresponding to the second moment will be adjusted in the opposite direction compared to the first moment, so if they are all in the corresponding increasing state, it means that no adjustment is required), then maintain the current demand water pressure XQ i constant;

[0061] If not, this moment is taken as the current moment and step S1 is executed again (when the normal floor of water consumption changes, the relevant reference for adjustment will change, because the water pressure may be sufficient or insufficient when the user intervenes or leaves, so re-analysis and processing is required);

[0062] Specifically, this embodiment is mainly aimed at the water supply situation of normal floors. The processing method of this embodiment can not only effectively ensure that each floor can use water normally (that is, the corresponding water flow rate is infinitely close to the corresponding flow range, then the corresponding floors can use water normally), and secondly, the associated water supply pressure is adjusted under the premise of ensuring normal water use, so as to effectively avoid energy loss and waste, and can achieve a better energy saving effect. The reason for energy waste is that there is a highest floor and several other floors in the same period, and the heights of the other floors are relatively low. In order to meet the highest water supply of the highest floor, the water supply pressure used is the largest, but this type of water supply pressure is more than enough for the water supply of other floors. In order to ensure the normal water supply of high floors, the corresponding water pressure can be appropriately reduced so that the water flow rate of high-rise water tends to the corresponding center line or the lowest line, and the corresponding water flow rates of the several floors below will also decrease accordingly and tend to the corresponding center line. Then, the flow monitoring method can be used to ensure the synchronous water supply between multiple floors and achieve a better water supply treatment effect.

[0063] The cycle management center defines a set of monitoring cycles based on the calibrated abnormal floor, identifies the water flow curve of the abnormal floor within the monitoring cycle, identifies whether there is a minimum water use line in the water flow curve, and if there is a minimum water use line, defines a set of monitoring time periods to identify whether there is a minimum water use line simultaneously in other control floors located above the abnormal floor, and performs signal display based on the identification result, wherein the specific method of determining the minimum water use line of the abnormal floor is:

[0064] Based on the marked abnormal floors, a set of monitoring cycles is confirmed from the current moment. The monitoring cycle is a preset cycle, which is prepared by the operator in advance based on experience and is generally set at 1 hour.

[0065] Based on the water flow monitored by the real-time flow monitoring terminal, the water flow curve generated by the abnormal floor during this monitoring period is confirmed. The horizontal coordinate axis of this curve is the timeline, and the vertical coordinate axis is the water flow;

[0066] The minimum water flow rate is identified from the water flow rate curve. If the minimum water flow rate = 0, it means that there is no minimum water line, and the abnormal floor is marked as a normal floor. If the minimum water flow rate ≠ 0, the part of the line segment belonging to the minimum water flow rate in the water flow rate curve is marked, and the marked part of the line segment is marked as the minimum water line (there are two possibilities for the existence of the minimum water line at this time. The first possibility is that there is a water-using appliance in the corresponding floor that has been in a state of draining water, resulting in the minimum water line. Another possibility is that there is a water leakage in the corresponding water main, resulting in the minimum water line);

[0067] A set of monitoring periods is defined, and the monitoring period is a preset period, generally 24 hours. Other control floors located above the abnormal floor are marked as floors to be monitored, and it is identified whether the lowest water consumption line also exists in other floors to be monitored during this monitoring period. The determination method is consistent with the abnormal floor in determining the water flow curve within a set of monitoring cycles, and the lowest water consumption line is locked. If it exists, a pipeline inspection signal is generated. If it does not exist, a water consumption abnormality signal corresponding to the abnormal floor is generated;

[0068] Based on the determined pipeline inspection signal, the relevant operators can inspect the water pipeline for leaks from the height of the abnormal floor, identify whether there is a real leak, and handle it;

[0069] Based on the determined abnormal water usage signals, relevant operators can alert relevant owners of the corresponding floors, warning them whether there is water leakage or other conditions in their homes.

[0070] By adopting this processing method, it is not only possible to effectively identify whether there is a leak in the corresponding water supply pipeline, but also to identify whether there is abnormal water usage on the corresponding floor, thereby improving the overall control effect of the water supply.

[0071] Some of the data in the above formulas are dimensionless and numerically calculated. Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0072] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
