Description

Technical Field

[0001] This specification relates to the field of fluid system control, and particularly to a control method, system, medium, and electronic device for a fluid system. Background Art

[0002] A non-switching device refers to a device whose output states are more than just "on" and "off". Existing group control technologies simply consider the number of devices that are turned on when dealing with multi-machine parallel connection in a cold heat source fluid system. First, one device is turned on at 100% power, then another device is turned on until 100% and the next device is turned on in sequence until all devices are turned on. This results in relatively low overall energy efficiency. When dealing with multi-machine series connection in a cold heat source fluid system, remote sensors are usually installed at the farthest position of the system being served, which leads to slow response, low overall energy efficiency of the system, and inflexible setting of requirements for supply and load.

[0003] Therefore, there is a need to provide a control method, system, medium, and electronic device for a fluid system to efficiently and flexibly control non-switching devices. Summary of the Invention

[0020] As Figure 1 shown, application scenario 100 may include a processing device 110, a network 120, a user terminal 130, a storage device 140, and a fluid system control system.

In some embodiments, the processing device 110 may be directly connected to the user terminal 130 and the storage device 140 to access the information and / or data stored therein.

[0024] The user terminal 130 can obtain information or data in the application scenario 100, and the user (e.g., the user of the fluid system control system) can be the user of the user terminal 130. For example, the user terminal 130 can send a control instruction to the processing device 110 through the network 120. The processing device 110 can obtain energy parameters through the acquisition module of the fluid system control system according to the control instruction, and generate a control model based on the positional relationship and energy parameters between non-switching devices to control the non-switching devices. In some embodiments, the user terminal 130 can include one or any combination of a mobile device, a tablet computer, a laptop computer, etc. In some embodiments, the mobile device can include a wearable device, a smart mobile device, a virtual reality device, an augmented reality device, etc. or any combination thereof.

[0025] In some embodiments, the storage device 140 can be connected to the network 120 to communicate with one or more components in the application scenario 100 (e.g., the processing device 110, the user terminal 130, etc.).

For more descriptions about the fluid system control system, reference can be made to Figure 2 and its related descriptions.

[0027] It should be noted that the above description is provided for illustrative purposes only and is not intended to limit the scope of the present application. For those of ordinary skill in the art, various changes and modifications can be made under the guidance of the content of the present application. The features, structures, methods, and other features of the exemplary embodiments described in the present application can be combined in various ways to obtain additional and / or alternative exemplary embodiments. For example, the storage device 140 can be a data storage device including a cloud computing platform, such as a public cloud, a private cloud, a community cloud, and a hybrid cloud, etc. However, these changes and modifications do not depart from the scope of the present application.

[0028] It should be understood that Figure 1 The system and its modules shown can be implemented in various ways. It should be noted that the above description of the application scenario 100 is only for convenience of description and cannot limit this specification within the scope of the exemplified embodiments.

[0029] Figure 2 It is a schematic diagram of modules of a fluid system control system shown according to some embodiments of this specification.

[0030] As Figure 2 shown, a fluid system control system may include an acquisition module, a control model generation module, and a control module.

[0031] The acquisition module can be used to acquire one or more energy parameters of multiple non-switching devices in a cold and heat source fluid system. In some embodiments, the energy parameters of non-switching devices can be acquired through sensors. For more descriptions of the acquisition module, reference can be made to Figure 3 and its related descriptions, which will not be elaborated here.

[0032] The control model generation module can be used to generate one or more control models based on the positional relationship between multiple non-switching devices and one or more energy parameters. Among them, the positional relationship between multiple non-switching devices can include a series relationship and a parallel relationship. For more descriptions of the control model generation module, reference can be made to Figure 3 and its related descriptions, which will not be elaborated here.

[0033] The control module can be used to control multiple non-switching devices based on one or more control models. In some embodiments, the control module can control the opening and closing of multiple non-switching devices according to the control models. For example: in a central air conditioning system, a heat exchanger is used when the temperature difference is large enough, and a refrigeration unit is used when the temperature difference is small. The heat exchanger and the refrigeration unit can be connected in parallel. According to the control model, different valves can be controlled to determine which device to use and switch between the two sets of devices. For more descriptions of the first control module, reference can be made to Figure 3 and its related descriptions, which will not be elaborated here.

[0034] It should be noted that the above descriptions of the acquisition module, the control model generation module, and the control module are only for the convenience of description and do not limit this specification within the scope of the examples given. It can be understood that for those skilled in the art, after understanding the principle of the system, they may, without departing from this principle, make any combination of each module, or form a subsystem and connect it with other modules. In some embodiments, Figure 2 the acquisition module, the control model generation module, and the control module disclosed in

[0035] Figure 3It is an exemplary flowchart of a fluid system control method shown in some embodiments of this specification.

[0036] As Figure 3 shown, a fluid system control method includes the following steps. In some embodiments, a fluid system control method can be executed by a fluid system control system and a processing device 110.

[0037] Step 310, obtain one or more energy parameters of multiple non-switching devices in a cold and heat source fluid system. In some embodiments, step 310 can be executed by an acquisition module.

[0038] A cold and heat source refers to a non-switching device that provides low-temperature fluid to remove heat or provides thermal energy to output energy. Among them, the fluid refers to flowing liquid or gas. A non-switching device refers to a device whose output state is more than just "on" or "off", such as: variable frequency pump, blower, variable frequency water pump, variable frequency chiller, dimming lamp, variable speed fan, etc. For example: The cold source can include a cooling tower, a condenser, etc. The heat source can include a boiler, a geothermal heat exchanger, etc. A cold and heat source fluid system refers to a fluid system that includes a cold source and / or a heat source. For example: a cooling system, a water cooling system, a heating system, a constant temperature system, an air conditioning system. An energy parameter refers to a parameter that can reflect the energy consumption of a non-switching device. The energy parameter can include voltage, current, power, duty cycle, temperature, flow rate, head, valve opening angle, and pressure. In some embodiments, the energy parameters of non-switching devices can be obtained through corresponding sensors. For example, temperature sensors, pressure sensors, current sensors, voltage sensors, power sensors, and flow meters can be used to obtain the temperature, pressure, current, voltage, power, and flow rate when the water pump is running.

[0039] Step 320, generate one or more control models based on the positional relationship between multiple non-switching devices and one or more energy parameters. In some embodiments, step 320 can be executed by a control model generation module.

[0040] In some embodiments, the positional relationship between multiple non-switching devices includes a series relationship and / or a parallel relationship. As Figure 5 shown, the series non-switching devices can include a cold / heat source, a pump, a heat exchanger, a refrigeration unit, a pump, and a cold / heat load. As Figure 6 shown, the parallel devices can include 1 to n refrigeration units. One or more first control models can be generated based on the series relationship and one or more energy parameters and / or one or more second control models can be generated based on the parallel relationship and one or more energy parameters. It can be understood that the appendix of this specification Figure 5 and 6A schematic diagram showing the series and parallel positional relationships of multiple non-switching devices. The positions and types of the non-switching devices can be adjusted, and the types of the non-switching devices can be the same or different. This embodiment is only for illustrative purposes and does not limit this specification to the scope of the examples given.

[0041] In some embodiments, in response to the positional relationship between multiple non-switching devices being a series relationship, one or more first control models for controlling the non-switching devices in the subsequent circuit are generated based on one or more energy parameters corresponding to the non-switching devices in the previous circuit. In some embodiments, the first control model can be a machine learning model. Among them, the input of the machine learning model is the name of the non-switching device in the previous stage, the corresponding energy parameter, and the name of the non-switching device in the subsequent stage (for example, heat exchanger, flow rate, water pump), and the output of the machine learning model is the energy parameter (flow rate) corresponding to the non-switching device in the subsequent stage. The machine learning model can include, but is not limited to, neural network (NN), convolutional neural network (CNN), deep neural network (DNN), recurrent neural network (RNN), etc. or any combination thereof. For example, the machine learning model can be a model formed by combining a convolutional neural network and a deep neural network.

[0042] The specific process of establishing the first control model can be as follows: An initial machine learning model is established in advance, the name of the non-switching device in the previous stage, the corresponding energy parameter, and the name of the non-switching device in the subsequent stage are obtained, and a first training sample is generated. The label of the first training sample is the energy parameter (for example, flow rate) corresponding to the non-switching device in the subsequent stage. Based on the first training sample, the parameters of the initial machine learning model are updated until the trained initial machine learning model meets the preset conditions, and a trained machine learning model is obtained. The preset conditions can be that the loss function converges, the value of the loss function is less than the preset value, or the number of iterations is greater than the preset number of times, etc.

[0043] For another example, if the device at the previous stage of the water pump is a heat exchanger, the flow rate inside the heat exchanger can be obtained through a sensor, and a first control model is established based on the flow rate of the heat exchanger to control the flow rate of the water pump. For example, if the flow rate of the heat exchanger does not meet the requirements, the first control model can be used to control the water pump to increase the flow rate. If the flow rate of the heat exchanger reaches the standard, the first control model can be used to control the water pump to maintain the flow rate.

[0044] Controlling the energy consumption of the non-switching device in the subsequent stage through the energy parameters of the non-switching device in the previous stage overcomes the drawback in the prior art that in order to meet the energy consumption of the non-switching device at the farthest end, the energy consumption of the remaining non-switching devices is increased. It has the advantages of reducing unnecessary energy consumption and increasing the flexibility of the system.

[0045] In some embodiments, in response to the positional relationship among the plurality of non-switching devices being a parallel relationship, one or more third control models are constructed. One or more fourth control models are obtained by adjusting one or more third control models based on one or more preset reference models; the global optimal solutions of one or more fourth control models are calculated to obtain one or more second control models.

[0046] In some embodiments, when the positional relationship among the plurality of non-switching devices is a parallel relationship, a third control model can be constructed according to the acquired energy parameters. In some embodiments, the corresponding relationship between the energy parameters of the non-switching devices and time can be obtained through linear regression fitting, non-linear regression fitting, exponential fitting, logarithmic fitting, etc. Taking the speed and load of a variable-frequency water pump as an example, after obtaining N data pairs of the speed and load of the variable-frequency water pump, the N data pairs are subjected to data fitting, and the function that most accurately describes the relationship between the speed and load is selected as the third control model. Specifically, a scatter plot can be first established based on the SPSS software according to the speed of the variable-frequency water pump at multiple time points and the load of the variable-frequency water pump corresponding to the multiple time points. Through various curve fitting forms (such as linear regression fitting, non-linear regression fitting, exponential fitting, logarithmic fitting, etc.), multiple candidate fitting curves are obtained, and the candidate fitting curve that best fits the scatter plot is selected as the third control model. It can be understood that different energy parameters of the selected non-switching devices result in different third control models. This embodiment is only for illustration and does not limit this specification within the scope of the examples given.

[0047] In some embodiments, one or more fourth control models can be obtained by adjusting one or more third control models based on one or more preset reference models. Among them, the preset reference models can be linear functions, other high-order functions, exponential functions, etc. The preset reference models can be obtained through linear regression methods. For example, the reference model of the current parameter and power signal of the variable-frequency water pump can be preset as: y = kx + b, where x can be the current parameter, y can be the power signal, and k and b can be obtained through sampling calculations. In some embodiments, the system may not only calculate k and b. The system may also add coefficients or constants, or may add variables. For more descriptions of the fourth control model, see Figure 4 and related descriptions.

[0048] In some embodiments, the global optimal solutions of one or more fourth control models can be calculated to obtain one or more second control models. In some embodiments, a high-dimensional control model can be obtained by superimposing one or more fourth control models of multiple non-switching devices, and the highest energy efficiency point of the high-dimensional control model is selected as the global optimal solution to obtain the second control model.

[0049] Step 330, controlling a plurality of non-switching devices based on one or more control models. In some embodiments, step 330 may be performed by a control module.

[0050] In some embodiments, a plurality of non-switching devices may be controlled according to a first control model and / or a second control model. For example, when the non-switching devices in a cold and heat source fluid system are in series, the non-switching devices may be controlled by the first control model; when the non-switching devices in a cold and heat source fluid system are in parallel, the non-switching devices may be controlled by the second control model; when the non-switching devices in a cold and heat source fluid system have both series and parallel relationships, the first control model and the second control model may be used for joint control. By using the first control model and the second control model to perform joint adjustment and control on the non-switching devices in the cold and heat source fluid system, the overall system energy consumption can be reduced and the system flexibility can be increased.

[0051] Figure 4 is an exemplary flowchart of obtaining a fourth control model according to some embodiments of the present specification.

[0052] As Figure 4 shown, the method for obtaining the fourth control model includes the following steps.

[0053] Step 410, comparing one or more third control models with corresponding preset one or more reference models. Step 410 may be performed by a control model generation module.

[0054] Among them, the preset reference model may be a linear function, other higher-order functions, exponential functions, etc. The preset reference model may be obtained by a linear regression method. For example, the reference model of the current parameter and power signal of a variable-frequency water pump may be preset as: y = kx + b, where x may be the current parameter, y may be the power signal, and k and b may be obtained by sampling calculation.

[0055] Step 420, performing data sampling on the data interval of one or more third control models that are closest to the preset one or more reference models. Step 420 may be performed by a control model generation module.

[0056] In some embodiments, the power change curve of a preset reference model can be compared with the third control model by fitting. Taking the current and voltage of a variable-frequency water pump as independent variables and the flow rate and head as dependent variables as an example, in the initial deployment, N test independent variable data points are uniformly input into the control range of the control components. After each change in the dependent variable stabilizes, the response timestamps from the start of the change to the next stable state are recorded, and the stable rotational speed is also recorded. After obtaining N state points in sequence, the power efficiency curve of the preset reference model is fitted, and the control interval with the mapping relationship y = f(x) obtained by fitting is intercepted.

[0057] Step 430: Perform data fitting based on the sampled data to obtain one or more fourth control models. Step 430 can be executed by the control model generation module.

[0058] Based on the obtained linear control interval above, read the change and stable intervals between each common control point, and further take values and fit the control curve within this interval to obtain the fourth control model. It can be understood that in order to improve the control accuracy, after reading the change and stable intervals between each common control point, more than one fitting can be performed, and the third control model can be continuously adjusted to obtain a more accurate fourth control model.

[0059] It should be noted that the above description of a control method for a fluid system is only for illustration and explanation, and does not limit the scope of application of this specification.
