Description

Technical Field

[0001] The present application relates to the technical field of emulsion pump station control systems, and in particular to a method and system for starting and stopping multiple emulsion pump stations based on a scoring mechanism. Background Art

[0002] In mining operations, emulsion pumping stations are key equipment, and their operating stability and efficiency directly affect the smooth progress of the entire operation process. At present, there are some emulsion pumping station control systems, but most systems still use traditional quantitative control methods, which cannot flexibly adjust the start and stop of the pumping station according to actual needs, resulting in energy waste and equipment wear; in order to improve this situation, some existing emulsion pumping station control systems use a single sensor to monitor the status of the pumping station and perform simple start and stop control based on preset thresholds. However, this method ignores the synergy and overall efficiency between multiple pumping stations and cannot achieve better resource allocation.

[0003] Therefore, it is necessary to design an emulsion pump station control system with an intelligent decision-making mechanism to achieve flexible adjustments according to actual working conditions and pump station status, improve the operating efficiency of the pump station, avoid serious energy waste, and reduce safety hazards caused by excessive wear of equipment. Summary of the invention

[0004] In order to realize the intelligent start and stop of multiple emulsion pumping stations, improve the overall operation efficiency and energy utilization of the emulsion pumping stations, and reduce equipment wear and safety hazards, the present application provides a start and stop control method and system for multiple emulsion pumping stations based on a scoring mechanism.

[0005] In a first aspect, the present application provides a method for starting and stopping multiple emulsion pump stations based on a scoring mechanism, comprising: real-time collection of operating data of each emulsion pump station, including: operating status, pressure, flow, operating time, load size, output power, input power, and fault records and storage;

[0006] The real-time score of each emulsion pumping station is calculated according to the preset scoring standard for the collected operation data of each emulsion pumping station; the real-time score of each emulsion pumping station is collected, and a coordinated adjustment strategy is generated according to the coordinated adjustment rule; the coordinated adjustment rule includes: if there are one or more emulsion pumping stations that meet the first condition, then one or more emulsion pumping stations that meet the condition are stopped accordingly and the number of stopped emulsion pumping stations is counted and recorded as the first number, and the first condition is that the real-time score is lower than the preset threshold; at the same time, all emulsion pumping stations that are currently in a stopped state and have no faults are obtained. Based on the historical scores of the pumping stations, among the emulsion pumping stations that are currently in the stopped state and not faulty, the first number of emulsion pumping stations are selected in descending order according to the historical scores and the requirement that the historical scores are greater than a preset threshold value to be turned on; if the number of emulsion pumping stations selected in descending order according to the historical scores and the requirement that the historical scores are greater than a preset threshold value is recorded as the second number, and the first number cannot be reached, the third number of standby emulsion pumping stations is turned on accordingly, wherein the third number is the difference between the first number and the second number; the corresponding emulsion pumping stations are turned on and off according to the coordinated adjustment strategy.

[0007] By adopting the above scheme, a scoring mechanism for the emulsion pump station is set up from multiple dimensions such as the operation data of the emulsion pump station, load size, energy efficiency and fault conditions. The coordinated adjustment strategy is set up using the real-time calculated score to dynamically adjust the start and stop status of the pump station, so that the emulsion pump station with a score lower than the preset threshold is stopped and replaced by an emulsion pump station with a higher score, so as to improve the overall operation efficiency and energy efficiency of the emulsion pump station and reduce equipment wear and safety hazards.

[0008] Preferably, the preset scoring criteria include: operating status score, energy efficiency ratio score, stability score and fault condition score, and the scoring result is a weighted sum of the operating status score, energy efficiency ratio score, stability score and fault condition score;

[0009] The operation status score is obtained by determining the preset range according to the pressure, flow, operation time and load size of each emulsion pump station collected in real time, and then matching the preset range with the corresponding preset score, and performing weighted summation; the energy efficiency ratio score is obtained by determining the preset range according to the ratio of output power to input power collected in real time, and then matching the preset score with the corresponding preset range;

[0010] The stability score is obtained by calculating the average pressure change rate or the average flow change rate based on the pressure or flow collected within a period of time including the current moment, and then matching the corresponding preset range with the corresponding preset score;

[0011] The fault condition score is obtained by calculating the fault frequency based on the fault records collected within a period of time including the current moment and determining the corresponding preset range, and then matching the corresponding preset score with the corresponding preset range.

[0012] By adopting the above scheme, each emulsion pump station is scored from four aspects: operating status, energy efficiency ratio, stability and fault frequency. The collected data is compared with the preset status range and the corresponding scores are matched to obtain the score value of each aspect more objectively. For example, the better the operating status and the higher the energy efficiency ratio, the higher the score.

[0013] Preferably, whether each emulsion is in the peak load period is determined based on the pressure and flow of each emulsion pumping station collected in real time, and the preset threshold of the corresponding emulsion pumping station is dynamically adjusted for each emulsion pumping station in the corresponding peak load period, and the preset score is correspondingly reduced based on the preset threshold.

[0014] By adopting the above scheme, considering that some specific operations on the emulsion pumping station will directly lead to rapid changes in the pressure and flow of the current emulsion pumping station, making the emulsion pumping station in the peak load period, the preset score threshold is dynamically adjusted for this situation. For example, during the peak load period, the threshold can be appropriately lowered to ensure a sufficient number of operating units; when the load is low, the threshold can be increased to reduce energy consumption and maintenance costs.

[0015] Preferably, it also includes:

[0016] The real-time operation data of each emulsion pump station collected is calculated using the computing device installed in each emulsion pump station in the on state to obtain a real-time score;

[0017] Establish a communication network for each emulsion pumping station. The real-time score of each emulsion pumping station will be sent to other emulsion pumping stations through the communication network for storage and information sharing;

[0018] The computing device installed in each emulsion pumping station is used to obtain the real-time scores of each stored emulsion pumping station, and a coordinated adjustment strategy is generated according to the coordinated adjustment rules, so that each emulsion pumping station can control the start and stop of its own emulsion pumping station according to the generated coordinated adjustment strategy.

[0019] By adopting the above solution and a distributed control strategy, each emulsion pump station can obtain scoring information in real time and generate an adjustment strategy, automatically completing its own start and stop adjustments, further improving the system's coordination and manageability, and reducing equipment wear and safety hazards.

[0020] Preferably, it also includes:

[0021] Using neural network technology, the pressure, flow, operation time, load size, output power, input power and fault records of each emulsion pump station are predicted respectively, and the pressure, flow, operation time, load size, output power, input power and fault condition of each emulsion pump station at the next moment are obtained, and the fault records are updated based on the fault condition;

[0022] According to the predicted pressure, flow, operation time, load size, output power, input power and fault record of each emulsion pump station at the next moment, the real-time score of each emulsion pump station in the open state at the next moment is calculated according to the preset scoring standard;

[0023] According to the predicted real-time scores of each emulsion pumping station at the next moment, a second coordinated adjustment strategy is generated according to the coordinated adjustment rules, and the generated second coordinated adjustment strategy replaces the generated coordinated adjustment strategy.

[0024] By adopting the above scheme, the operating status of each pumping station in the future is predicted and scored based on the historical data collected by the emulsion pumping station, and then a coordinated adjustment strategy is generated to make start and stop adjustments in advance to achieve more accurate start and stop control.

[0025] Preferably, it also includes:

[0026] A visual interface is designed for each emulsion pumping station to display in real time the corresponding start and stop of the emulsion pumping station according to the coordinated adjustment strategy.

[0027] By adopting the above scheme, a visual interface is designed for each emulsion pump station, which is convenient for management personnel to remotely monitor the emulsion pump station.

[0028] Preferably, the historical score is set to an average of the historical scores corresponding to a preset period of time adjacent to the current moment.

[0029] By adopting the above scheme, the score of each emulsion pumping station that is not turned on and has no faults at the current moment can be more accurately calculated by using the mean calculation method, so as to improve the overall operation efficiency and effectiveness.

[0030] In a second aspect, the present application provides a start-stop control system for multiple emulsion pumping stations based on a scoring mechanism, including: an emulsion pumping station operation data acquisition module, which is used to collect the operation data of each emulsion pumping station in real time, including: operation status, pressure, flow, operation time, load size, output power, input power and fault records and storage;

[0031] The emulsion pump station scoring calculation module is used to calculate the real-time score of each emulsion pump station according to the preset scoring standard based on the collected operation data of each emulsion pump station;

[0032] An emulsion pump station collaborative adjustment strategy acquisition module is used to collect the real-time scores of each emulsion pump station and generate a collaborative adjustment strategy according to the collaborative adjustment rules; the collaborative adjustment rules include: if there are one or more emulsion pump stations that meet the first condition, then one or more emulsion pump stations that meet the condition are stopped and the number of stopped emulsion pump stations is counted and recorded as the first number, and the first condition is that the real-time score is lower than the preset threshold; at the same time, the historical scores of all emulsion pump stations that are currently in a stopped state and not faulty are obtained, and the first number of emulsion pump stations are selected from the emulsion pump stations that are currently in a stopped state and not faulty according to the historical scores and the historical scores are required to be greater than the preset threshold. In descending order, they are opened; if the number of emulsion pump stations selected in descending order according to the historical scores and the historical scores are required to be greater than the preset threshold is recorded as the second number, and the first number cannot be reached, then a third number of standby emulsion pump stations are opened, wherein the third number is the difference between the first number and the second number;

[0033] The emulsion pump station coordinated adjustment strategy execution module is used to start and stop the corresponding emulsion pump station according to the coordinated adjustment strategy.

[0034] By adopting the above solution, intelligent start and stop control of multiple emulsion pumping stations is realized, effectively improving the overall operation efficiency and energy utilization of the pumping stations.

[0035] In a third aspect, the present application provides a computer-readable storage medium, wherein the computer-readable storage medium includes a stored computer program, wherein when the computer program is executed, the device where the computer-readable storage medium is located is controlled to execute the method as described above.

[0036] In a fourth aspect, the present application provides a computer device, comprising a memory, a processor, and a program stored and executable on the memory, wherein the program implements the steps of the above method when executed by the processor.

[0037] In summary, this application has the following beneficial effects:

[0043] Figure 2 It is a schematic diagram of the structure of the start-stop control system of multiple emulsion pump stations based on the scoring mechanism described in the specific embodiment. DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0045] like Figure 1 As shown, the embodiment of the present application discloses a method for starting and stopping multiple emulsion pump stations based on a scoring mechanism, and the specific steps are as follows:

[0046] S1. Collect and store the operating data of each emulsion pump station in real time.

[0047] Specifically, the operating data includes: operating status data, including the start or stop status and whether it is a fault status, pressure, flow, operating time, including the operating time of a single start and the cumulative operating time, output power, input power and fault records, including: the number of operating faults in a single start and the cumulative number of operating faults.

[0048] The operation data of each emulsion pump station is collected in real time, and the operation data is stored in the order of collection time. In this embodiment, the operation data stored is updated and covered based on a single day of 24 hours.

[0049] S2. Calculate the real-time score of each emulsion pumping station according to the preset scoring criteria based on the collected operation data of each emulsion pumping station.

[0050] Specifically, the preset scoring criteria include the division of different dimensions such as operation status score, energy efficiency ratio score, stability score and fault situation score; in this embodiment, the weighted average of the operation status score, energy efficiency ratio score, stability score and fault situation score is used to obtain the scoring result. Specifically, the specific settings of the score of each dimension include:

[0051] The operation status score is obtained by determining the preset ranges of the pressure, flow, operation time and load size of each emulsion pump station collected in real time, and then matching the preset scores with the preset ranges to obtain the weighted sum. Specifically, taking the pressure of the emulsion pump station as an example, the corresponding preset pressure ranges are set, such as the first preset pressure range [p1, p2], the second preset pressure range (p2, p3] and the Nth pressure range (p n-1 ,p n ]; Each corresponding pressure range is matched with a corresponding preset score, such as: the first pressure preset range [p1, p2] matches the score f1, the second pressure preset range (p2, p3] matches the score f2, the Nth pressure range (p n-1 ,p n ] Matching score fn; Similarly, for the parameter of flow rate, set the corresponding flow preset range, and each flow preset range is matched with a corresponding preset score; for the parameter of running time, you can choose to set the corresponding running time for a single start or the cumulative running time, and each preset range is matched with a corresponding preset score; for the parameter of load size, the setting is the same as the flow parameter. For the pressure p0 of the emulsion pump station collected in real time, determine the pressure preset range, such as the second pressure preset range, and match the corresponding score f2; Similarly, obtain the scores matched by flow rate, running time, and load respectively, and perform weighted summation of all matching scores to obtain the final operating status score; wherein, the higher the operating status score, the better the operating status of the emulsion pump station.

[0052] The energy efficiency ratio score is obtained by determining the preset range according to the ratio of the output power to the input power collected in real time, and then matching the preset score with the preset range determined accordingly; specifically, the energy efficiency ratio is calculated according to the ratio of the output power to the input power collected in real time, and the calculation formula is: output power of the emulsification pump / input power of the emulsification pump)×100%, and an energy efficiency ratio preset range is set corresponding to the energy efficiency ratio, and each energy efficiency ratio preset range is matched with a preset score; for example: the first energy efficiency ratio preset range [0,γ1] matches the score T1, the second energy efficiency ratio preset range (γ1,γ2] matches the score T2, the Nth energy efficiency ratio range (γ n-1 ,γ n ] Matching score Tn. According to the output power and input power of the emulsion pump station collected in real time, determine the preset range of energy efficiency ratio, and then match the corresponding score to obtain the energy efficiency ratio score; among them, the higher the energy efficiency ratio score, the better the energy efficiency of the emulsion pump station.

[0053] The stability score is obtained by calculating the average pressure change rate or average flow change rate based on the pressure or flow collected within a period of time including the current moment, and then matching the corresponding preset range with the corresponding preset score. Specifically, taking flow fluctuation as a stability score indicator, the flow collected within a period of time including the current moment is obtained. In this embodiment, the period of time is set to the 5 minutes before the current moment. The flow difference between each sampling moment and the previous sampling moment is calculated and divided by the sampling time interval to obtain a corresponding flow change rate value, and the flow change rate in all time periods is calculated and averaged to obtain the average flow change rate. For the average flow change rate parameter, a preset range of the average flow change rate is set, and each range of the average flow change rate is matched with a score value. For the real-time flow of the collected emulsion pump station, the preset range of the average flow change rate is determined, and then the corresponding score is matched to obtain the stability score. Among them, the higher the stability score, the more stable the operation of the emulsion pump station.

[0054] The fault condition score is obtained by calculating the fault frequency based on the fault records collected within a period of time including the current moment, and then matching the corresponding preset range with the corresponding preset score. Specifically, the fault records collected within a period of time including the current moment are obtained to determine the number of faults. In this embodiment, the fault records are determined based on the number of operating faults in a single start. The fault frequency is calculated by dividing the number of faults by the operating time (the operating time since a single start), and a fault frequency preset range is set for the fault frequency. Each fault frequency preset range corresponds to a matching preset score. For the collected fault records of the emulsion pump station, the fault frequency is determined, and then the corresponding score is matched to obtain the fault condition score; wherein, the lower the fault frequency, the higher the fault condition score, indicating that the emulsion pump station is less likely to fail.

[0055] Taking into account that there are emulsion pumping stations that are in a stopped state or a faulty state, some operating data does not exist for these emulsion pumping stations, and no score calculation is performed. Therefore, the real-time score of each emulsion pumping station that is in the turned-on state is calculated based on the above preset scoring criteria.

[0056] S3. Collect the real-time scores of each emulsion pumping station and generate a coordinated adjustment strategy according to the coordinated adjustment rules.

[0057] Considering that the start and stop control of the emulsion pump station and the startup of the standby pump station are directly carried out according to the scoring results, the coordinated control of different pump stations is not taken into account. The comprehensive scoring results are used to stop an emulsion pump station with a score value lower than the preset threshold, and start an emulsion pump station with a historical score value higher than the preset threshold. Compared with directly starting a standby emulsion pump station (whose operating status and energy efficiency are unclear), it is more guaranteed that the efficiency of the overall emulsion pump station will be improved. Therefore, the real-time score of each emulsion pump station is obtained and the real-time score of each emulsion pump station is stored sequentially according to time, and then a real-time coordinated adjustment strategy is generated according to the coordinated adjustment rules based on the obtained real-time score.

[0058] Specifically, the coordinated adjustment rules include:

[0059] If there are one or more emulsion pumping stations that meet the first condition, then the one or more emulsion pumping stations that meet the condition will be stopped accordingly, and the number of stopped emulsion pumping stations will be counted, which is recorded as the first number; wherein, each emulsion pumping station is numbered, and the first condition is that the real-time score is lower than the preset threshold; for example: the real-time scores corresponding to the emulsion pumping stations numbered 006 and 017 are 60 points and 63 points respectively, and the corresponding threshold score is 70. For this situation, a coordinated adjustment strategy for stopping the emulsion pumping stations numbered 006 and 017 is generated, and the number of stopped emulsion pumping stations is counted to obtain the first number of 2.

[0060] At the same time, the historical scores of all the emulsion pumping stations that are currently in a stopped state and not faulty are obtained, and the first number of emulsion pumping stations are selected in descending order according to the historical scores and the requirement that the historical scores are greater than a preset threshold value from the various emulsion pumping stations that are currently in a stopped state and not faulty, and are turned on accordingly; if the number of emulsion pumping stations selected in descending order according to the historical scores and the requirement that the historical scores are greater than a preset threshold value is recorded as the second number, and the first number cannot be reached, then the third number of standby emulsion pumping stations are turned on accordingly, wherein the third number is the difference between the first number and the second number; wherein, the historical score refers to the score obtained by real-time calculation during the operation of each emulsion pumping station that is currently in a stopped state and not faulty, which can be set to the score corresponding to the moment before the operation stopped or the average of the historical scores corresponding to a preset period of time near the current moment, such as: the average of all historical scores 4 hours before the current moment.

[0061] For example: the historical scores of all emulsion pumping stations numbered 009, 023, and 0025 that are currently in a stopped state and have no faults are 95, 92, and 72 points respectively. Then, according to the historical scores and requiring that the historical scores are greater than the preset threshold, two emulsion pumping stations, i.e., emulsion pumping stations numbered 009 and 0023, are selected in descending order. For this situation, a coordinated adjustment strategy for opening emulsion pumping stations numbered 009 and 023 is generated. In addition, if the only emulsion pumping station numbered 009 that is currently in a stopped state and has no faults is emulsion pumping station numbered 009, a coordinated adjustment strategy for opening the emulsion pumping station numbered 009 and opening 1 spare emulsion pumping station is generated for this situation.

[0062] In addition, considering that there may be certain specific operations that will cause each emulsion pump station to be at a peak load, thus affecting the real-time score judgment of each emulsion pump station, in order to reduce the impact of the peak load on the real-time score and ensure that there are enough emulsion pump stations working, you can choose to dynamically set the preset threshold. Specifically,

[0063] According to the real-time collected pressure and flow of each emulsion pumping station, determine whether each emulsion is in the peak load period. For example, determine the pressure peak range composed of the pressure peak and the flow peak range composed of the flow peak based on the collected pressure and flow of an emulsion pumping station in a period of time adjacent to the current moment. If the pressure at the current moment is in the pressure peak range and the flow at the current moment is in the flow peak range, determine whether it is in the peak load period. Dynamically adjust the preset threshold of the corresponding emulsion pumping station for each emulsion pumping station in the corresponding load peak period, and reduce the preset score accordingly based on the preset threshold. For example, the preset threshold of the emulsion pumping station in the peak load period is reduced by 10 points.

[0064] S4. Start and stop the corresponding emulsion pumping station according to the coordinated adjustment strategy.

[0065] Specifically, a collaborative adjustment strategy generated in real time based on the scoring is obtained, and start and stop instructions are generated accordingly based on the collaborative adjustment strategy, and the start and stop of each emulsion pumping station is completed based on the instructions.

[0066] In addition, a visualization interface can be designed for each emulsion pumping station. The visualization interface can display the emulsion pumping stations corresponding to each number in real time, with a green status indicator light indicating that the emulsion pumping station is in the on state, and a red status indicator light indicating that the emulsion pumping station is in the stopped (closed) state. The corresponding opening and stopping of the emulsion pumping stations according to the coordinated adjustment strategy can be displayed in real time, making it convenient for management personnel to monitor the operating status of each emulsion pumping station in real time.

[0067] In a specific embodiment, in order to further complete the automatic and timely start and stop adjustment of the emulsion pump station and further improve the coordination of the overall emulsion pump station, the method further includes:

[0068] The real-time operation data of each emulsion pump station collected is calculated using the computing device installed in each emulsion pump station in the on state to obtain a real-time score;

[0069] A communication network is established for each emulsion pumping station, and the real-time score of each emulsion pumping station will be sent to other emulsion pumping stations through the communication network for storage and information sharing.

[0070] Specifically, wireless communication is selected to complete the communication between each emulsion pumping station. The real-time score calculated by each emulsion pumping station will be transmitted to other emulsion pumping stations in real time, and the transmitted real-time score will be associated with the number information of the corresponding pumping station. When receiving the real-time score, other emulsion pumping stations will store the real-time score according to the number information and time of the pumping station.

[0071] The computing device installed in each emulsion pumping station is used to obtain the real-time scores of each stored emulsion pumping station, and a coordinated adjustment strategy is generated according to the coordinated adjustment rules, so that each emulsion pumping station can control the start and stop of its own emulsion pumping station according to the generated coordinated adjustment strategy.

[0072] Specifically, compared with a centralized server completing the real-time scoring calculation of all emulsion pumping stations, distributed scoring calculation is implemented by using computing devices installed in each emulsion pumping station to speed up the scoring calculation, and the collaborative adjustment strategy is obtained by calculating according to the same collaborative adjustment rules, so that each emulsion pumping station can be quickly adjusted according to the generated collaborative adjustment strategy.

[0073] In a specific embodiment, in order to achieve more accurate intelligent start and stop control of each emulsion pump station, the method further includes:

[0074] Using neural network technology, the pressure, flow, operation time, load size, output power, input power and fault records of each emulsion pump station are predicted respectively, and the pressure, flow, operation time, load size, output power, input power and fault condition of each emulsion pump station at the next moment are obtained, and the fault record is updated based on the fault condition. For example, taking the emulsion pump station numbered 006 as an example, the pressure at several historical moments obtained by the emulsion pump station is trained using the constructed LSTM neural network to predict the pressure value at the next moment; for the fault records at several historical moments obtained by the emulsion pump station, the time when the fault was generated is determined, and the historical fault situation and the corresponding time are used as training data. The neural network is used to predict whether a fault will occur at the next moment. If a fault occurs, the fault record is updated with the fault situation at that moment.

[0075] According to the predicted pressure, flow, operating time, load size, output power, input power and fault record of each emulsion pumping station at the next moment, the real-time score of each emulsion pumping station that is in the on state at the next moment is calculated according to the preset scoring standard; among them, each emulsion pumping station that is in the on state at the next moment is determined according to the generated collaborative adjustment strategy; and the predicted pressure, flow, operating time, load size, output power, input power and fault condition of the emulsion pumping station that is in the stopped state and has no fault at the current moment and is in the on state at the next moment are initialized and set for each emulsion pumping station.

[0076] According to the predicted real-time scores of each emulsion pump station at the next moment, a second coordinated adjustment strategy is generated according to the coordinated adjustment rules, and the generated second coordinated adjustment strategy replaces the generated coordinated adjustment strategy. For example, if the score of the emulsion pump station numbered 006 at the current moment is 70, no stop control will be performed. If the score is 68 at the next moment, the emulsion pump station numbered 006 can be stopped in advance to reduce equipment wear and safety hazards of the emulsion pump station.

[0077] like Figure 2 As shown, the embodiment of the present application discloses a start-stop control system for multiple emulsion pump stations based on a scoring mechanism, specifically comprising:

[0078] The emulsion pump station operation data acquisition module 101 is used to collect and store the operation data of each emulsion pump station in real time, including: operation status, pressure, flow, operation time, load size, output power, input power and fault records;

[0079] The emulsion pump station score calculation module 102 is used to calculate the real-time score of each emulsion pump station according to the preset score standard based on the collected operation data of each emulsion pump station;

[0080] The emulsion pump station collaborative adjustment strategy acquisition module 103 is used to collect the real-time scores of each emulsion pump station and generate a collaborative adjustment strategy according to the collaborative adjustment rules; the collaborative adjustment rules include: if there are one or more emulsion pump stations that meet the first condition, then one or more emulsion pump stations that meet the condition are stopped and the number of stopped emulsion pump stations is counted and recorded as the first number, and the first condition is that the real-time score is lower than the preset threshold; at the same time, the historical scores of all emulsion pump stations that are currently in a stopped state and not faulty are obtained, and the first number of emulsion pump stations are selected from the emulsion pump stations that are currently in a stopped state and not faulty according to the historical scores and the historical scores are required to be greater than the preset threshold in descending order to be opened; if the number of emulsion pump stations selected in descending order according to the historical scores and the historical scores are required to be greater than the preset threshold is recorded as the second number, and the first number cannot be reached, then the third number of standby emulsion pump stations are opened, wherein the third number is the difference between the first number and the second number;

[0081] The emulsion pump station coordinated adjustment strategy execution module 104 is used to start and stop the corresponding emulsion pump station according to the coordinated adjustment strategy.

[0082] In a specific embodiment, the system further includes:

[0083] The emulsion pump station start and stop control display interface 105 is used to design a visualization interface for each emulsion pump station to display in real time the corresponding start and stop of the corresponding emulsion pump station according to the coordinated adjustment strategy.

[0084] The emulsion pump station collaborative adjustment strategy acquisition module 103 is also used to determine whether each emulsion is in a load peak period based on the pressure and flow of each emulsion pump station collected in real time, and dynamically adjust the preset threshold of the corresponding emulsion pump station when each emulsion pump station is in the corresponding load peak period, and reduce the preset score accordingly based on the preset threshold.

[0085] In a specific embodiment, the emulsion pump station score calculation module 102 is further used to calculate the real-time operation data of the collected emulsion pump station itself using the calculation device installed in each emulsion pump station in the on state to obtain the real-time score;
