[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, article, or apparatus that includes that element.

[0034] The terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0035] First, a brief introduction to the application scenarios involved in this application will be given.

[0036] Energy is a core element of economic development. Almost all production, transportation, and service activities depend on energy supply. Ensuring energy security can guarantee the normal operation of industry, agriculture, and service industries, and promote sustained economic growth, making it of great importance.

[0037] There is a crucial interrelationship between oil transportation system control and energy security. Effective oil transportation system control is fundamental to ensuring energy security, which in turn is a vital support for sustainable economic, social, and environmental development. With the continuous growth of energy demand and the increasing complexity of the supply environment, improving the intelligence and automation levels of oil transportation system control will contribute to enhancing energy security and promoting comprehensive economic and social development.

[0038] Currently, there is no independently developed water hammer prevention function in domestically produced process control systems (PCSs), resulting in insufficient promotion of domestically produced PCS in oil pipelines and control systems, and reducing the autonomy, security, and controllability of industrial control systems. Therefore, there is an urgent need to develop functions for effective control of oil transportation systems to improve their operational stability.

[0039] This application addresses the aforementioned problems by providing a control method for an oil transportation system. The method acquires operational information of the pipelines and pumps within the system, and determines the energy efficiency assessment result based on this information. The energy efficiency assessment result includes either abnormal or normal energy efficiency. Furthermore, when the assessment result indicates abnormal energy efficiency, the method further acquires the operating efficiency of the oil transportation system and controls the operating state of the pump units based on this efficiency. Therefore, this application can be used to effectively control an oil transportation system and improve its operational stability.

[0040] Next, a brief introduction will be given to the implementation environment (implementation architecture) involved in this application.

[0041] like Figure 1The diagram shown is a structural schematic of an oil transportation system control system provided in an embodiment of this application. The oil transportation system control system may include a computer device 101 and a data acquisition device 102. The oil transportation system control method provided in this embodiment can be applied to the computer device 101.

[0042] It should be noted that the number of computer devices 101 and data acquisition devices 102 included in the above-mentioned oil transportation system control system is only an example, and the embodiments of this application do not limit this.

[0043] Figure 1 The computer device 101 is used to acquire various data in the oil transportation system from the acquisition device 102 and to control the oil transportation system based on the acquired data.

[0044] In one possible implementation, computer device 101 can be divided into a data acquisition module, a system resource optimization module, a logic calculation module, a triggering mechanism module, and an execution mechanism module. The data acquisition module can acquire pipeline operation information and oil pump operation information from acquisition device 102 within the oil transportation system. The system resource optimization module can calculate the oil utilization rate and oil pump load rate based on the data acquired by the data acquisition module, evaluate the energy efficiency of the oil transportation system based on the calculation results, and transmit the results to the logic calculation module. The logic calculation module calculates the oil pump rate, oil pump speed, and valve opening based on the operating parameters in the oil transportation system to further determine the working efficiency of the oil transportation system and sends the working efficiency of the oil transportation system to the triggering mechanism module. The triggering mechanism module can use a single-read rising edge and uniqueness filtering plugin to control the effective trigger count to one, and trigger a control signal based on the working efficiency value of the oil transportation system. The execution mechanism module can use an execution delay and count control plugin to control the execution strategy to trigger three times after a 2-second delay, and control the start and stop of the pump based on the control signal triggered by the triggering mechanism module, and send alarm information to the control center. Thus, this application can support the implementation of water hammer early protection function that performs independent logical operations.

[0045] Optionally, the computer device 101 described above can be a terminal or a server. The terminal can be a personal computer such as a desktop, tablet, or laptop computer, or a remote terminal, user terminal (TE), or mobile device. The server can be a single server (such as a cloud server) or a server cluster consisting of multiple servers. A server cluster can also be called a computer device cluster. In some embodiments, the server cluster can also be a distributed cluster. This application does not limit the form of the computer device 101.

[0046] Figure 1The data acquisition device 102 is used to collect various data in the oil transportation system and send them to the computer device 101. For example, the data acquisition device 102 can be an oil pressure sensor, etc.

[0047] In terms of hardware implementation, the aforementioned computer device 101 can be implemented through, for example... Figure 2 The structure shown is implemented as follows. Figure 2 The diagram shown is a structural schematic of a computer device provided in an embodiment of this application. Figure 2 The computer device shown may include a processor 201, a memory 202, a communication interface 203, and a bus 204. The processor 201, the memory 202, and the communication interface 203 can be connected via the bus 204.

[0048] The processor 201 is the control center of the computer device. It can be a general-purpose central processing unit (CPU) or other general-purpose processors. The general-purpose processor can be a microprocessor or any conventional processor.

[0049] As an example, processor 201 may include one or more CPUs, for example Figure 2 CPU0 and CPU1 are shown in the diagram.

[0050] The memory 202 may be a read-only memory (ROM) or other type of static storage device capable of storing static information and instructions, random access memory (RAM) or other type of dynamic storage device capable of storing information and instructions, or electrically erasable programmable read-only memory (EEPROM), disk storage media or other magnetic storage devices, or any other medium capable of carrying or storing desired program code in the form of instructions or data structures and accessible by a computer, but is not limited thereto.

[0051] In one possible implementation, the memory 202 can exist independently of the processor 201. The memory 202 can be connected to the processor 201 via a bus 204 and is used to store data, instructions, or program code. When the processor 201 calls and executes the instructions or program code stored in the memory 202, it can identify the object to be identified.

[0052] In another possible implementation, the memory 202 can also be integrated with the processor 201.

[0053] Communication interface 203 is used for connecting computer equipment to other devices via a communication network, such as Ethernet, radio access network (RAN), wireless local area network (WLAN), etc. Communication interface 203 may include a receiving unit for receiving data and a transmitting unit for transmitting data.

[0054] Bus 204 can be an industry standard architecture (ISA) bus, a peripheral component interconnect (PCI) bus, or an extended industry standard architecture (EISA) bus, etc. This bus can be divided into address bus, data bus, control bus, etc. For ease of representation, Figure 2 The bus is represented by a single thick line, but this does not mean that there is only one bus or one type of bus.

[0055] It should be pointed out that, Figure 2 The structure shown does not constitute a limitation on computer equipment, except Figure 2 In addition to the components shown, a computer device may include more or fewer components than illustrated, or combine certain components, or have different component arrangements.

[0056] For ease of understanding, the oil transportation system control method provided in this application will be described in detail below with reference to the accompanying drawings.

[0057] like Figure 3 The diagram shown is a flowchart illustrating an oil transportation system control method provided in an embodiment of this application. Figure 3 The oil pipeline system control method shown can be applied to the above. Figure 1 The computer equipment in the middle. This computer equipment can be based on Figure 2 The structure shown is implemented as follows. The method includes: S301-S304.

[0058] S301. Obtain the operating information of pipelines and oil pumps in the oil transportation system.

[0059] The oil transportation system is a complete set of equipment consisting of pipelines, oil pumps, and feed pumps used to transport oil.

[0060] Pipeline operation information may include the actual oil volume transported through the pipeline, i.e., the actual amount of oil transported through the pipeline. Alternatively, pipeline operation information may also include information such as pipeline pressure and temperature.

[0061] The operating information of the oil pump may include the oil pump flow rate, which refers to the actual volume or mass of oil transported by the oil pump.

[0062] In one possible implementation, the data acquisition device can be connected to sensors installed at pipelines and oil pumps in the oil transportation system. The sensors acquire pipeline and oil pump operating information and transmit this information to a computer. The computer can then receive the pipeline and oil pump operating information from the data acquisition device.

[0063] S302. Based on the pipeline operation information and the oil pump operation information, determine the energy efficiency assessment results of the oil transportation system.

[0064] The energy efficiency assessment results include either abnormal energy efficiency or normal energy efficiency.

[0065] Computer equipment can determine the oil utilization rate and pump load rate of the oil transportation system based on pipeline operation information and pump operation information. Furthermore, the computer equipment can determine the energy efficiency assessment results of the oil transportation system based on the oil utilization rate and pump load rate.

[0066] S303. Obtain the working efficiency of the oil transportation system when the energy efficiency assessment results indicate abnormal energy efficiency.

[0067] The operating efficiency of the oil transportation system reflects the energy utilization efficiency and transportation efficiency of the oil transportation system during the oil transportation process.

[0068] If the energy efficiency assessment results indicate an energy efficiency anomaly, it suggests that the oil pump load rate is high, the oil utilization rate is low, and there is energy waste. In this case, computer equipment can obtain the working efficiency of the oil transportation system to rationally adjust the working status of the pump units in the oil transportation system, thereby improving the energy efficiency anomaly.

[0069] S304. Control the working status of the pump units in the oil transportation system according to the working efficiency of the oil transportation system.

[0070] The pump set in the oil transportation system may include multiple oil pumps. When the oil transportation system is operating, the multiple oil pumps in the pump set can be turned on simultaneously or partially to meet the oil transportation demand.

[0071] For example, computer equipment can compare the operating efficiency of the oil transportation system with a pre-set efficiency threshold to further determine whether to suspend or start the oil pumps in the oil transportation system based on the comparison results, thereby improving the abnormal energy efficiency.

[0072] In one embodiment, during S302 above, when the computer device determines the energy efficiency assessment result of the oil transportation system based on the pipeline operation information and the oil pump operation information, this application embodiment provides an optional implementation method, including: S3021-S3023.

[0073] S3021. Determine the oil utilization rate of the oil transportation system based on the actual oil transport volume of the pipeline, the pipeline energy loss efficiency, the operating efficiency of the oil transportation system, the correction factor, and the reference oil volume.

[0074] The oil utilization rate is calculated as the ratio of the product of the actual oil transported by the pipeline, the pipeline energy loss efficiency, the operating efficiency of the oil transport system, and the correction factor, to the reference oil volume. The reference oil volume can be the total oil volume input into the oil transport system.

[0075] The actual oil transport volume of the pipeline, the pipeline energy loss efficiency, the operating efficiency of the oil transport system, the correction factor, the reference oil volume, and the oil utilization rate of the oil transport system can satisfy the first formula. The first formula is as follows:

[0076]

[0077] Where Zyly represents the oil utilization rate of the oil transportation system. Qa represents the actual oil transportation volume of the pipeline. Eg represents the pipeline energy loss efficiency. Ec represents the operating efficiency of the oil transportation system. Cx is a correction factor, ranging from 0 to 1, which can be dynamically assigned. Ql represents the reference oil volume.

[0078] S3022. Determine the load rate of the oil pump based on the oil pump flow rate, oil pump head, oil density, gravitational acceleration, and fixed power of the oil transfer system.

[0079] The load factor is equal to the product of the oil pump flow rate, the oil pump head, the oil density, and the gravitational acceleration, and the ratio to the fixed power of the oil transportation system.

[0080] The oil pump flow rate, oil pump head, oil density, gravitational acceleration, fixed power of the oil transfer system, and oil pump load rate can satisfy the second formula. The second formula is as follows:

[0081]

[0082] Where Bdfz is the load rate of the oil transfer pump, Qs is the flow rate of the oil transfer pump, Hb is the head of the oil transfer pump, ρ is the oil density, gk is the acceleration due to gravity, and Pe is the stationary power of the oil transfer system.

[0083] S3023. Determine the energy efficiency assessment results of the oil transportation system based on the oil utilization rate and load rate.

[0084] For example, computer equipment can determine whether there is an energy efficiency anomaly in the oil transportation system by judging the relationship between the oil utilization rate and the utilization rate threshold, as well as the load rate of the oil pump and the load rate threshold.

[0085] For example, computer equipment can use a two-dimensional matrix evaluation method, constructing a four-quadrant evaluation matrix with oil utilization rate as the vertical axis and load rate as the horizontal axis. Furthermore, the computer equipment can determine whether there are energy efficiency anomalies in the oil transportation system based on the currently calculated oil utilization rate and the zone in which the oil pump load rate is located.

[0086] In one embodiment, when the computer device determines the energy efficiency assessment result of the oil transportation system based on the oil utilization rate and load rate in S3023 above, this application embodiment provides an optional implementation method, including: S30231-S30232.

[0087] S30231. If the oil utilization rate is greater than or equal to the utilization rate threshold and the load rate is less than or equal to the load rate threshold, then the energy efficiency assessment result is determined to be normal.

[0088] S30232. If the oil utilization rate is less than the utilization rate threshold, or the load rate is greater than the load rate threshold, then the energy efficiency assessment result is determined to be an energy efficiency anomaly.

[0089] The utilization threshold and load rate threshold can be flexibly set based on experience. For example, the utilization threshold can be 80% or 85%, and the load rate threshold can be 40% or 45%. This application does not impose any limitations on these settings.

[0090] Therefore, if the oil utilization rate is greater than or equal to the utilization rate threshold and the load rate is less than or equal to the load rate threshold, it indicates that the oil transportation system is making full use of energy and operating under reasonable conditions. Computer equipment can confirm that the energy efficiency is normal.

[0091] If the oil utilization rate is less than the utilization rate threshold, it indicates that the oil transportation system is not utilizing energy sufficiently. Alternatively, if the load rate of the oil pumps is greater than the load rate threshold, it indicates that the oil transportation system is operating under unreasonable conditions. In these cases, computer equipment can identify energy efficiency anomalies and further optimize the system.

[0092] In one embodiment, when the computer device obtains the working efficiency of the oil transportation system in S303 above, this application embodiment provides an optional implementation method, including: S3031-S3032.

[0093] S3031. Obtain the operating parameters of the oil transportation system.

[0094] The operating parameters of the oil transportation system may include the inlet and outlet cross-sectional area of ​​the oil pump, the average flow velocity of the fluid inside the oil pump, the average oil volume, the diameter of the oil pump, the oil viscosity, the valve flow coefficient, the valve flow area, the pressure difference before and after the valve, and the oil density.

[0095] For example, the inlet cross-sectional area of ​​an oil pump can be the fluid flow area at the inlet or outlet flange of the oil pump. The average fluid velocity within the pump is used to represent the average velocity of the fluid within the pump. The average oil volume is used to represent the average volume of oil flowing through the oil pump per unit time.

[0096] S3032. Determine the working efficiency of the oil transportation system based on its operating parameters.

[0097] Computer equipment can calculate the oil pump rate, oil pump speed, and valve opening based on the operating parameters of the oil transportation system, in order to further calculate the working efficiency of the oil transportation system.

[0098] In one embodiment, when the computer device determines the working efficiency of the oil transportation system based on the operating parameters of the oil transportation system in S3032 above, this application embodiment provides an optional implementation method, including: S30321-S30324.

[0099] S30321. Determine the pump speed based on the inlet and outlet cross-sectional areas of the pump and the average flow velocity of the fluid inside the pump.

[0100] The oil pump speed is equal to the product of the inlet and outlet cross-sectional areas of the oil pump and the average flow velocity of the fluid inside the oil pump.

[0101] The pump speed, the inlet and outlet cross-sectional areas of the pump, and the average flow velocity of the fluid inside the pump can satisfy the third formula. The third formula is as follows:

[0102] Bdsl=Amhj×V.

[0103] Where Bdsl is the pump speed, Amhj is the inlet and outlet cross-sectional area of ​​the pump, and V is the average flow velocity of the fluid inside the pump.

[0104] S30322. Determine the oil pump speed based on the average oil volume, oil pump diameter, and oil viscosity.

[0105] The oil pump speed is equal to the ratio of the average oil volume to the first product. The first product is equal to the product of a preset coefficient, the cube of the oil pump diameter, and the oil viscosity. The preset coefficient can be flexibly set based on experience and is not limited.

[0106] The average oil volume, pump diameter, oil viscosity, and pump speed satisfy the fourth formula. The fourth formula is as follows:

[0107]

[0108] Where Bdzs is the oil pump speed, Yljz is the average oil volume, δ is a preset coefficient (e.g., 0.0314), and Dp is the oil pump diameter. This refers to the viscosity of the oil.

[0109] S30323. Determine the valve opening degree based on the valve flow coefficient, valve flow area, pressure difference across the valve, and oil density.

[0110] The valve opening is equal to the product of the valve flow coefficient, the valve flow area, and a first ratio. The first ratio is determined based on the pressure difference across the valve and the oil density.

[0111] The valve flow coefficient, valve flow area, pressure difference across the valve, oil density, and valve opening degree can satisfy the fifth formula. The fifth formula is as follows:

[0112]

[0113] Where Fmkd is the valve opening degree, Cxs is the valve flow coefficient, Ar is the valve flow area, ΔP is the pressure difference across the valve, and ρ is the oil density.

[0114] S30324. Determine the working efficiency of the oil transfer system based on the oil pump rate, oil pump speed, and valve opening.

[0115] For example, computer equipment can input the oil pump rate, oil pump rotation speed, and valve opening degree into a target prediction model for processing to obtain the operating efficiency of the oil transportation system. The target prediction model can be pre-trained on a machine learning model based on multiple sets of sample data. A set of sample data may include a corresponding set of sample oil pump rates, sample oil pump rotation speeds, sample valve opening degrees, and sample operating efficiencies.

[0116] In one embodiment, in the above S30324, when the computer device determines the working efficiency of the oil delivery system based on the oil pump rate, oil pump speed and valve opening, this application embodiment provides an optional implementation method, including: step A.

[0117] Step A: Determine the working efficiency of the oil transfer system based on the mechanical efficiency of the oil transfer pump, the oil transfer pump rate, the oil transfer pump speed, and the valve opening.

[0118] The working efficiency of the oil transportation system is equal to the product of the mechanical efficiency of the oil pump, the oil pump speed, and the oil pump rotation speed, and the ratio of the valve opening degree.

[0119] The operating efficiency of the oil transportation system, the mechanical efficiency of the oil pump, the pump speed, the pump rotation speed, and the valve opening can satisfy the sixth formula. The sixth formula is as follows:

[0120]

[0121] Where Gzzb represents the operating efficiency of the oil transfer system. Jxxl represents the mechanical efficiency of the oil pump. Bdsl represents the oil pump speed. Bdzs represents the oil pump rotation speed. Fmkd represents the valve opening degree.

[0122] In one embodiment, when the computer device controls the working state of the pump group in the oil transportation system according to the working efficiency of the oil transportation system in S304, this application embodiment provides an optional implementation method, including: S3041 and S3042.

[0123] S3041. If the working efficiency is greater than or equal to the efficiency threshold, the running oil pump in the control pump group shall stop working.

[0124] The efficiency threshold can be flexibly set based on experience. For example, the efficiency threshold can be 0.9 or 1. This application does not impose any limitations on this.

[0125] The computer equipment can compare the operating efficiency with an efficiency threshold to obtain a comparison result. If the comparison result indicates that the operating efficiency is greater than or equal to the efficiency threshold, it suggests that there may be a large number of operating oil pumps in the pump set. Continuing to operate these multiple pumps could lead to energy waste. In this case, the computer equipment can control the operating oil pumps in the pump set to stop working.

[0126] For example, a computer device can select a preset number of operating oil pumps from multiple operating oil pumps in a pump group, and control the selected preset number of operating oil pumps to stop working. The preset number can be 1 or 2, etc.

[0127] For example, computer equipment can select a preset proportion of operating oil pumps from multiple operating oil pumps in a pump group according to a preset ratio, and control the selected preset proportion of operating oil pumps to stop working.

[0128] S3042. If the working efficiency is less than the efficiency threshold, the non-operating oil pump in the control pump group will start working.

[0129] If the comparison result indicates that the working efficiency is less than the efficiency threshold, it may indicate that the number of operating oil pumps in the pump set is insufficient, and the oil transportation system may be in a state of substandard efficiency or abnormal load. In this case, the computer equipment can control the non-operating oil pumps in the pump set to start working, so as to support the normal operation of the oil transportation system.

[0130] For example, a computer device can select a preset number of non-operational oil pumps from multiple non-operational oil pumps in a pump group, and control the selected preset number of non-operational oil pumps to start working.

[0131] In one embodiment, the oil transportation system control method provided in this application further includes: S401.

[0132] S401 Output alarm information to indicate abnormal energy efficiency.

[0133] Based on this, the computer equipment can send alarm information to the control center so that staff can understand the operation of the oil transportation system in a timely manner.
