Description

Technical Field

[0001] The present invention relates to the technical field of pump rooms, and in particular to a pump room control method, device, electronic equipment and storage medium. Background Art

[0002] A pump house is a building where water pumps, power machines and their auxiliary equipment are installed. Its main function is to provide power for various water supply, drainage, irrigation and other systems, and to transport water from one place to another through water pumps; for example, in the city's water supply system, the pump house takes water from the water source (such as rivers, lakes, groundwater, etc.), and then transports the water to the water treatment plant for purification, and then transports the treated water to various areas of the city through a series of pump houses, including residential areas, commercial centers, factories, etc., to meet people's living and production water needs.

[0003] During the water supply control process, the pump room generally confirms the height of the highest water-using floor based on the total water consumption of the corresponding water-using floors, confirms its water supply echelon through its height, and then directly uses the water pump associated with the corresponding echelon for pressurization based on the confirmed water supply echelon. However, in the actual processing process, the higher the echelon, the higher the pressurization energy consumption generated by the water pump, and the high-gradient pressure data is not reasonably distributed, and the subsequent low-gradient water pumps are not appropriately used for pressurization, thereby failing to effectively reduce energy consumption. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a pump room control method, device, electronic equipment and storage medium, which solve the problems of unreasonable distribution of high-gradient pressure data and inappropriate use of subsequent low-gradient water pumps for pressurization processing.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A pump room control method, comprising the following steps:

[0006] Step 1: Monitor the water pressure of the pipelines associated with the water supply floor in real time. When the water pressure in the pipeline decreases, mark the water supply floor as the water use floor, and confirm the water supply demand pressure of the water use floor based on the associated height of the water use floor. The specific sub-steps are as follows:

[0007] S11, monitor the water pressure of the associated pipelines of the water supply floors involved in the corresponding pump room in real time, and calibrate the real-time monitored water pressure as SY i , where i represents different water supply floors;

[0008] S12, if the water pressure SY monitored on the corresponding water supply floor i Meet: (BY-SY i)≥0.05MPa, a low pressure state signal is generated, where BY is the preset standard floor water pressure, and the duration T of the low pressure state signal based on this water supply floor i , if T i ≥10S, then the water supply floor is marked as the water use floor. If T i If the time is less than 10S, no calibration will be performed on this water supply floor;

[0009] If the water pressure SY monitored on the corresponding water supply floor i Not satisfied: (BY-SY i ) ≥0.05MPa, no signal is generated;

[0010] S13: Based on the determined water-using floor, confirm the floor value G of the water-using floor i , using P i =G i ×3×g×ρ confirms the water supply demand pressure P of this floor i , where g is the acceleration due to gravity and ρ is the density of water;

[0011] Step 2: Based on the different water-using floors confirmed at the same time, the highest water-using floor is determined based on the values ​​of the different water-using floors. By confirming the water supply echelon to which the highest water-using floor belongs, it is determined whether to confirm direct water supply or confirm the optimal water supply logic. The specific method is as follows:

[0012] Based on the floor values ​​of different water-using floors confirmed at the same time, the highest water-using floor with the largest floor value is confirmed, and the floor value G of the highest water-using floor is confirmed. i , confirm the highest water consumption floor G at the current moment i The water supply team to which it belongs:

[0013] If G i ∈[1, 6], it means that the highest water consumption floor at the current moment belongs to the first water supply echelon, and municipal water supply is used without the intervention of water pump groups;

[0014] If G i ∈[7, 18], which means that the highest water consumption floor at the current moment belongs to the second water supply echelon, confirming the water supply demand pressure P of the highest water consumption floor at the current moment i , directly adjust the frequency of the water pump group in the second water supply echelon so that the output water pressure of the water pump group reaches P i And provide real-time water supply;

[0015] If G i ∈[19, ZG], where ZG is the highest floor of the corresponding water supply floor, which means that the highest water consumption floor at the current moment belongs to the third water supply echelon, and the specific confirmation of the optimal water supply logic is directly carried out;

[0016] Step 3: From the historical completion data, confirm the energy consumption loss of the pump groups of the second water supply echelon and the third water supply echelon under different working frequency states, and based on the specific energy consumption loss data, lock the energy consumption ranges associated with different pump groups under different working frequency states. The specific sub-steps are:

[0017] S31. Confirm several groups of energy consumption loss data associated with the single working frequency of the water pump group of the second water supply echelon and the water pump group of the third water supply echelon from the historical completion data, and mark the confirmed several groups of energy consumption loss data as energy consumption data sets associated with the single working frequency of the water pump group, and each different working frequency corresponds to a different energy consumption data set;

[0018] S32, processing the energy consumption data set associated with a single group of operating frequencies: re-arranging the different energy consumption data in the set in ascending order according to the value, and starting from the first value after sorting, confirming the difference between adjacent values, and preparing the sorted energy consumption data set as {J1, J2, ..., J n}, where J1 is the minimum energy consumption value, J n For the maximum energy consumption value, use Cz=|J q -J q+1 |Confirm the difference between adjacent values, where q belongs to [1, n-1];

[0019] If Cz≤Y1, where Y1 is a preset value, the energy consumption value associated with this difference Cz is calibrated to a similar value;

[0020] If Cz>Y1, no calibration is performed;

[0021] Starting from J1 and confirming step by step, the numerical segments with the same numerical values ​​are marked as the same characteristic segments;

[0022] Based on the different similar characteristic segments confirmed by the energy consumption data set, a group of characteristic segments with the largest energy consumption values ​​in the same characteristic segments are selected as characteristic segments, and based on the minimum and maximum values ​​within the selected characteristic segments, a numerical interval is confirmed, and this numerical interval is used as the energy consumption interval associated with the water pump group under this working frequency working state;

[0023] S33, sequentially determining the energy consumption intervals associated with the water pump groups in the second water supply echelon under different working frequencies and working states, and then sequentially confirming and recording several groups of energy consumption intervals associated with the water pump groups in the third water supply echelon;

[0024] Step 4: For the relevant moments where the optimal water supply logic needs to be confirmed, the water supply demand water pressure corresponding to the highest water use floor at the corresponding moment is determined first, and then based on the pressure values ​​associated with the second water supply echelon pump group and the third water supply echelon pump group under different working frequency states, a random combination is performed to confirm several groups of pressure combination sequences, and then based on the different energy consumption ranges associated with different water pump groups under different working frequency states, the pressure combination sequence with the lowest energy consumption value is selected as the optimal water supply logic, and this optimal water supply logic is used for water supply. The specific sub-steps are as follows:

[0025] S41, based on the water supply demand water pressure P of the highest water-using floor at the corresponding moment i , and then confirm the different pressures associated with different working frequencies of different water pump groups, where the working frequencies and the corresponding different pressures are all preset data, so that the different pressures associated with the water pump groups of the second water supply echelon and the water pump groups of the third water supply echelon are randomly combined, so that the combined pressure data sum ZH satisfies: ZH≥P i And (ZH-P i )≤Y2, where Y2 is the preset value. During the combination process, different water pump groups select one set of pressure data for combination, and a single water pump group cannot select multiple sets of pressure data for combination;

[0026] S42, sorting different pressure data satisfying the combination condition to generate a pressure combination sequence, then confirming the water pump group to which the different pressure data in the pressure combination sequence belong, thereby confirming the working frequency associated with the corresponding pressure data, combining the associated working frequencies, and confirming the working frequency combination sequence;

[0027] S43, confirming the water pump groups to which the different working frequencies belong from the working frequency combination sequence, and thereby confirming the different energy consumption intervals corresponding to the different working frequencies based on the different energy consumption intervals associated with the different working frequencies in the corresponding water pump groups;

[0028] After confirming the different energy consumption intervals associated with different working frequencies in a single group of working frequency combination sequences, summing up the minimum values ​​of several groups of energy consumption intervals to confirm the sum of the minimum values, and then summing up several groups of maximum values ​​to confirm the sum of the maximum values, and confirming the characteristic interval belonging to this single group of working frequency combination sequences based on the sum of the minimum values ​​and the sum of the maximum values;

[0029] The characteristic intervals of other working frequency combination sequences are confirmed in turn in the same manner;

[0030] S44, locking the middle value of the corresponding characteristic interval, taking the middle value as the characteristic value of this characteristic interval, selecting the working frequency combination sequence with the smallest characteristic value state as the optimal sequence, and taking the pressure combination sequence corresponding to the optimal sequence as the optimal water supply logic.

When there is a decrease in pipeline water pressure, the water supply floor is marked as a water-using floor, and the water supply demand water pressure of the water-using floor is confirmed based on the associated height of the water-using floor.

[0033] The water supply logic confirmation end determines the highest water-using floor based on the different water-using floors confirmed at the same time and the values ​​of the different water-using floors. By confirming the water supply echelon to which the highest water-using floor belongs, it confirms whether to directly supply water or confirms the best water supply logic;

[0034] The historical data processing end confirms the energy consumption loss of the water pump groups of the second water supply echelon and the third water supply echelon under different working frequency states from the historical completion data, and based on the specific energy consumption loss data, locks the energy consumption ranges associated with different water pump groups under different working frequency states;

[0035] At the optimization and regulation control end, for the relevant moments when the optimal water supply logic needs to be confirmed, the water supply demand water pressure corresponding to the highest water use floor at the corresponding moment is determined first, and then based on the pressure values ​​associated with the second water supply echelon water pump group and the third water supply echelon water pump group under different working frequency states, a random combination is performed to confirm several groups of pressure combination sequences, and then based on the different energy consumption ranges associated with different water pump groups under different working frequency states, the pressure combination sequence with the lowest energy consumption value is selected as the optimal water supply logic, and this optimal water supply logic is used for water supply.

[0036] Preferably, a storage medium for pump room control is used to store different energy consumption intervals associated with different operating frequencies of different water pump groups, wherein the different water pump groups belong to different water supply echelons;

[0039] The present invention determines the water-using floor by real-time monitoring of the pipeline water pressure in the pump room control area, and then identifies the water supply echelons to which the water-using floor belongs based on the height area where the water-using floor is located, and confirms the water supply execution logic based on the identification result, and confirms whether direct water supply or logic optimization is required;

[0040] Based on the confirmed water supply floor, confirm the water supply pressure associated with the corresponding water supply floor, and then based on the corresponding water supply pressure and the pressure performance of other floors or multiple echelons, make relevant confirmation of the pressure combination, and select the pressure through the comprehensive pressure performance of the secondary water supply echelon and the tertiary water supply echelon. Based on the determined pressure value, pressure distribution can be carried out, and the second and third echelons will provide comprehensive pressure supply. This pressure supply method can effectively ensure the full optimization of its energy consumption and simultaneously ensure normal water use on the corresponding floors.

[0042] Figure 2 It is a schematic diagram of the principle framework of the device of the present invention. DETAILED DESCRIPTION

[0043] 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.

[0044] First embodiment

[0045] See also Figure 1 , the present application provides a pump room control method, comprising the following steps:

[0046] Step 1: Monitor the water pressure of the pipelines associated with the water supply floors in real time. When there is a decrease in pipeline water pressure, mark the water supply floor as a water-using floor, and confirm the water supply demand pressure of the water-using floor based on the associated height of the water-using floor. Specifically, install a pressure sensor on the water supply main pipeline of each floor. When the pressure sensor detects a certain drop in pressure (such as from 0.3MPa to 0.25MPa) and lasts for a certain period of time (such as more than 10 seconds), it can be determined that there are users on the floor using water. The specific sub-steps for confirming the water supply demand pressure of the water-using floor are as follows:

[0047] S11, monitor the water pressure of the associated pipelines of the water supply floors involved in the corresponding pump room in real time, wherein the corresponding pressure sensor collects the pressure data in real time during the real-time monitoring process, and calibrates the real-time monitored water pressure as SY i , where i represents different water supply floors;

[0048] S12, if the water pressure SY monitored on the corresponding water supply floor i Meet: (BY-SY i)≥0.05MPa, a low pressure state signal is generated, where BY is the preset standard floor water pressure, representing the water pressure parameter without any water use, generally taking the value of 0.3MPa. Based on this, the duration of the low pressure state signal of the water supply floor is T i , if T i ≥10S, the water supply floor will be marked as the water-using floor (for the confirmed water-using floor, the relevant water pump is required to carry out hydraulic transportation to ensure the normal water use of the corresponding water-using floor. After the water supply, when the water-using floor does not need water, the corresponding real-time monitored water pressure will increase, so that the water pressure monitored on the corresponding floor will gradually approach 0.3MPa. Therefore, during the process of water pressure increase, when the water pressure reaches the standard, the corresponding floor will not be marked as the water-using floor, and the water supply treatment will be stopped). If T i If the time is less than 10S, no calibration will be performed on this water supply floor;

[0049] If the water pressure SY monitored on the corresponding water supply floor i Not satisfied: (BY-SY i ) ≥0.05MPa, no signal is generated;

[0050] S13: Based on the determined water-using floor, confirm the floor value G of the water-using floor i (Each pressure sensor on a different floor has a different related mark. When the pressure signal monitored by the pressure sensor on the fifth floor changes, it can be directly determined that the water-using floor is the fifth floor). i =G i ×3×g×ρ confirms the water supply demand pressure P of this floor i , where g is the acceleration due to gravity and ρ is the density of water;

[0051] After the water-using floor is calibrated, it does not immediately transform into the original normal floor. Instead, there is a period of time. When the water is supplied, the water pressure is gradually increased, and the corresponding floor is also using water. Therefore, there is a period of time for the water-using floor to transform into a normal floor.

[0052] Step 2: Based on the different water-using floors confirmed at the same time, the highest water-using floor is determined based on the values ​​of the different water-using floors. By confirming the water supply echelon to which the highest water-using floor belongs (primary water supply, secondary water supply or tertiary water supply, etc., primary water supply belongs to municipal water supply, the floor is low, and no water pump intervention is required, and secondary water supply and tertiary water supply both require water pump intervention), it is determined whether to confirm direct water supply or confirm the best water supply logic (direct water supply is the situation where the best water supply logic cannot be determined, so direct water supply is required), wherein the specific method of confirmation is:

[0053] S21, based on the floor values ​​of different water-using floors confirmed at the same time, confirm the highest water-using floor with the largest floor value, and confirm the floor value G of the highest water-using floor i , confirm the highest water consumption floor G at the current moment i The water supply team to which it belongs:

[0054] If G i ∈[1, 6], it means that the floor with the highest water consumption at the current moment belongs to the first water supply echelon and does not need any treatment (water can be directly supplied based on the pressure of municipal water without pressurization treatment), where 1 and 6 represent floors;

[0055] If G i ∈[7, 18], which means that the highest water consumption floor at the current moment belongs to the second water supply echelon, confirming the water supply demand pressure P of the highest water consumption floor at the current moment i , directly adjust the frequency of the water pump group in the secondary water supply area so that the output water pressure of the water pump group reaches P i And provide real-time water supply;

[0056] If G i ∈[19, ZG], where ZG is the highest floor of the corresponding water supply floor, which is preset in advance by the relevant operators, indicating that the highest water consumption floor at the current moment belongs to the third water supply echelon, and directly confirms the specific optimal water supply logic, so that the water pump groups in the secondary water supply area and the tertiary water supply area can be used in combination, which can not only ensure the normal transportation of water power, but also ensure the effective saving of energy, and achieve a better water pump control effect;

[0057] Step 3: From the historical completion data, confirm the energy consumption loss of different pump groups in different water supply echelons under different working frequency states, and based on the specific energy consumption loss data, lock the energy consumption range associated with different pump groups under different working frequency states. The specific sub-steps for locking the energy consumption range are:

[0058] S31. Confirm several groups of energy consumption loss data associated with single working frequencies of different water pump groups (that is, two groups of water pump groups, namely, the water pump group of the second water supply echelon and the water pump group of the third water supply echelon) in different water supply echelons from the historical completion data (that is, different energy consumption data generated by a water pump group when it is running at a certain working frequency, and different energy consumption loss situations exist in each different execution situation), and mark the confirmed several groups of energy consumption loss data as energy consumption data sets associated with the single working frequency of this water pump group, and each different working frequency corresponds to a different energy consumption data set;

[0059] S32, processing the energy consumption data set associated with a single group of operating frequencies: re-arranging the different energy consumption data in the set in ascending order according to the value, and starting from the first value after sorting, confirming the difference between adjacent values, and preparing the sorted energy consumption data set as {J1, J2, ..., J n}, where J1 is the minimum energy consumption value, J n For the maximum energy consumption value, use Cz=|J q -J q+1 |Confirm the difference between adjacent values, where q belongs to [1, n-1];

[0060] If Cz≤Y1, where Y1 is a preset value, and its specific value is determined by the operator based on experience, then the energy consumption value associated with this difference Cz is calibrated as a similar value;

[0061] If Cz>Y1, no calibration is performed;

[0062] Starting from J1 and confirming step by step, the value segments with the same value are marked as the same characteristic segments (for example: J1 and J2 are the same value, J2 and J3 are the same value, J3 and J4 are not the same value, then the three sets of energy consumption values ​​associated from J1 to J3 belong to a same characteristic segment);

[0063] Based on the different similar feature segments confirmed by this energy consumption data set, a group of feature segments with the largest energy consumption values ​​in the same feature segment is selected as the feature segment (if there are multiple selected feature segments, they are randomly determined, that is, there are multiple similar feature segments with the largest and identical values), and based on the minimum and maximum values ​​within the selected feature segment, the value interval is confirmed, and this value interval is used as the energy consumption interval associated with this water pump group under this working frequency working state;

[0064] S33, sequentially determining the energy consumption intervals associated with the water pump groups in the secondary water supply echelon under different working frequencies, and then sequentially confirming and recording several groups of energy consumption intervals associated with the water pump groups in the tertiary water supply echelon, and storing the records in a corresponding storage medium;

[0065] Step 4: For the relevant moments where the optimal water supply logic needs to be confirmed, the water supply demand water pressure corresponding to the highest water use floor at the corresponding moment is determined first, and then based on the pressure values ​​associated with the internal water pump groups of different water supply echelons under different working frequency states, a random combination is performed to confirm several groups of pressure combination sequences, and then based on the different energy consumption ranges associated with different water pump groups under different working frequency states, the pressure combination sequence with the lowest energy consumption value is selected as the optimal water supply logic, and this optimal water supply logic is used for water supply. The specific sub-steps for determining the optimal water supply logic are as follows:

[0066] S41, based on the water supply demand water pressure P of the highest water-using floor at the corresponding moment i , and then confirm the different pressures associated with different working frequencies of different water pump groups, where the working frequencies and the corresponding different pressures are all preset data (different working frequencies correspond to different pressure data, and different water pump groups are preset with different execution frequencies, which are preset in advance by relevant operators in the storage medium), so that the different pressures associated with different water pump groups in different water supply echelons are randomly combined, so that the sum of the combined pressure data ZH satisfies: ZH≥P i And (ZH-P i )≤Y2, where Y2 is the preset value. During the combination process, different water pump groups select one set of pressure data for combination. A single water pump group cannot select multiple sets of pressure data for combination. The specific value is determined by the operator based on experience. The general value is 0.05MPa, which means that the comprehensive pressure data can be larger than the required water supply pressure, but not too large;

[0067] S42, sorting different pressure data satisfying the combination condition to generate a pressure combination sequence, then confirming the water pump group to which the different pressure data in the pressure combination sequence belong, thereby confirming the working frequency associated with the corresponding pressure data, combining the associated working frequencies, and confirming the working frequency combination sequence;

[0068] S43, confirming the water pump groups to which the different working frequencies belong from the working frequency combination sequence, and thereby confirming the different energy consumption intervals corresponding to the different working frequencies based on the different energy consumption intervals associated with the different working frequencies in the corresponding water pump groups;

[0069] After confirming the different energy consumption intervals associated with different working frequencies in a single group of working frequency combination sequences, summing up the minimum values ​​of several groups of energy consumption intervals to confirm the sum of the minimum values, and then summing up several groups of maximum values ​​to confirm the sum of the maximum values, and confirming the characteristic interval belonging to this single group of working frequency combination sequences based on the sum of the minimum values ​​and the sum of the maximum values;

[0070] The characteristic intervals of other working frequency combination sequences are confirmed in turn in the same manner;

[0071] S44. Lock the middle value of the corresponding characteristic interval, use this middle value as the characteristic value of this characteristic interval, select the working frequency combination sequence with the smallest characteristic value state as the optimal sequence, use the pressure combination sequence corresponding to the optimal sequence as the optimal water supply logic, and perform logical control based on the different pressure data executed by different water pump groups within this optimal water supply logic to complete the floor water supply work at the corresponding time, and perform associated control on different water pump groups.

[0072] Specifically, it is planned that there is a user on the 23rd floor who is using water in the corresponding stage. During the water use process, there is a corresponding water supply pressure on the 23rd floor. This water supply pressure can be directly supplied by the third water supply echelon, but there is corresponding energy loss when the third water supply echelon supplies water. When the third water supply echelon is supplying water, its pressure can be comprehensively reflected by the pressures of the secondary water supply echelon and the tertiary water supply echelon to select the pressure. Based on the determined pressure value, pressure distribution can be carried out, and the second and third echelons can provide comprehensive pressure supply. This pressure supply method can effectively ensure the full optimization of its energy consumption.

[0076] The water supply logic confirmation end determines the highest water-using floor based on the different water-using floors confirmed at the same time and the values ​​of the different water-using floors. By confirming the water supply echelon to which the highest water-using floor belongs, it confirms whether to directly supply water or confirms the best water supply logic;

[0077] The historical data processing end confirms the energy consumption loss of different water pump groups in different water supply echelons under different working frequency states from the historical completion data, and based on the specific energy consumption loss data, locks the energy consumption range associated with different water pump groups under different working frequency states;

[0078] At the optimization and regulation control end, for the relevant moments when the optimal water supply logic needs to be confirmed, the water supply demand water pressure corresponding to the highest water use floor at the corresponding moment is determined first, and then based on the pressure values ​​associated with the water pump groups within different water supply echelons under different working frequency states, a random combination is performed to confirm several groups of pressure combination sequences, and then based on the different energy consumption ranges associated with different water pump groups under different working frequency states, the pressure combination sequence with the lowest energy consumption value is selected as the optimal water supply logic, and this optimal water supply logic is used for water supply.
