Technical Field

[0001] The present application relates to the field of intelligent control technology, and in particular to a cold source scheduling method, device and storage medium based on a configuration model. Background Art

[0002] At present, although many cold source systems on the market have achieved automated control, most of them cannot visually see the real-life model of the cold source system through the front-end interface. In addition, the front-end interface of the traditional cold source system mainly performs display functions, and there is a relatively obvious separation between it and the control of the cold source equipment. It is impossible to directly and effectively control the operation of the cold source equipment through the front-end configuration model interface and intuitively receive real-time feedback on the equipment's operating status. The interactivity between the two is poor, resulting in low efficiency in cold source scheduling.

[0049] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0050] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0051] At present, although many cold source systems on the market have achieved automated control, most of them cannot visually see the real-life model of the cold source system through the front-end interface. In addition, the front-end interface of the traditional cold source system mainly performs display functions, and there is a relatively obvious separation between it and the control of the cold source equipment. It is impossible to directly and effectively control the operation of the cold source equipment through the front-end configuration model interface and intuitively receive real-time feedback on the equipment's operating status. The interactivity between the two is poor, resulting in low efficiency in cold source scheduling.

[0052] In view of the above problems, the present application proposes a cold source scheduling method based on a configuration model. In response to the first trigger operation of the model icon in the configuration model, the model configuration interface corresponding to the model icon is displayed. In response to the configuration action received by the model configuration interface corresponding to the model icon, the device identifier of the cold source device is obtained, and the model icon is bound to the cold source device corresponding to the device identifier. Then, in response to the trigger operation of the operation mode control in the configuration model interface, the operation mode of the cold source device corresponding to the configuration model is determined, and the cold source device is controlled to operate according to the operation mode. Finally, in response to the second trigger operation of the model icon in the configuration model, the operation data of the cold source device corresponding to the model icon is displayed.

[0053] The above method enables users to intuitively build and display the cold source equipment model through a graphical interface through the steps of building and configuring the configuration model, equipment binding and interactive settings, operating mode control, and operating data display, so as to achieve accurate positioning and parameter configuration of the equipment. By directly controlling the equipment and adjusting the parameters in the configuration model interface and obtaining the equipment operating data in real time, it supports flexible control and real-time monitoring of the equipment operating mode, which helps to achieve efficient operation and refined management of the cold source system, enhances the interactivity of the system, and improves the efficiency of cold source scheduling.

[0054] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, etc., or an electronic device capable of realizing the above functions, etc. The following takes the cold source scheduling system based on the configuration model as an example to illustrate this embodiment and the following embodiments.

[0055] Based on this, the first embodiment proposed in this application provides a cold source scheduling method based on a configuration model, referring to Figure 1 In this embodiment, the cold source scheduling method based on the configuration model includes steps S10 to S40:

[0056] Step S10, in response to a first trigger operation of a model icon in the configuration model, displaying a model configuration interface corresponding to the model icon.

[0057] It should be noted that the configuration model is a cold source equipment model constructed by the user according to actual needs, which displays the cold source equipment and their relationships in a graphical way to facilitate user monitoring and management. The first trigger operation refers to a specific interactive action performed by the user on a model icon in the configuration model, such as single-click, double-click or long-press, etc., which is used to express the user's intention to configure the cold source equipment represented by the model icon. The model configuration interface is an interface for configuring a specific model icon. It can display various configurable parameters and options related to the cold source equipment type represented by the model icon, such as basic information of the equipment, operating parameter range, control logic, etc. When the user's first trigger operation on the model icon is detected, the system loads and displays the model configuration interface corresponding to the model icon so that the user can perform further configuration operations.

[0058] Step S20, in response to a configuration action received by the model configuration interface corresponding to the model icon, obtaining a device identifier of a cold source device, and binding the model icon to the cold source device corresponding to the device identifier.

[0059] It should be noted that configuration actions refer to various operations performed by users in the model configuration interface, such as entering information in a text box, selecting options from a drop-down menu, adjusting slider parameters, etc. These operations are used to define the specific configuration of the cold source device. The device identifier is the unique identifier of the cold source device. It can be the device number, name, or other information that can uniquely distinguish the device. It is used to accurately identify and locate specific cold source devices in the system. When the user completes the configuration action in the model configuration interface, the system will extract the device identifier information, and then establish an association between the current model icon and the cold source device corresponding to the device identifier, that is, a binding relationship. In this way, subsequent operations on the model icon can be mapped to the corresponding cold source device to achieve control and management of the device.

[0060] Optionally, after the model icon is bound to the cold source device, the interactive event and display label of the model icon are set corresponding to the configuration action received by the model configuration interface. Among them, the interactive event refers to the event triggered when the user performs a specific operation on the icon through an input device such as a mouse, and these events can trigger predefined behaviors or actions. Through the interactive event, the user can control the bound cold source device, such as starting, stopping, adjusting parameters, etc.; after the interactive event is triggered, the relevant information of the cold source device, such as the operating status, fault alarm, etc., can be obtained; the interactive event can also realize the page jump, such as opening the detailed information page of the device, the relevant monitoring screen, etc. Exemplarily, an interactive event is set as a click event, and the click event includes single click and double click, which means that the corresponding event behavior can be triggered by clicking or double clicking the mouse, and the event behavior includes opening a pop-up box, opening a link page, etc. The display label refers to the text, graphic or other information element associated with the model icon, which is used to show the user the key information related to the cold source device represented by the icon, such as the device name, number, current status, etc., to help the user quickly understand the situation of the cold source device.

[0061] Step S30, in response to the triggering operation of the operation mode control in the configuration model interface, determining the operation mode of the cold source device corresponding to the configuration model, and controlling the cold source device to operate according to the operation mode.

[0062] It should be noted that the configuration model interface is a visual interface for users to interact with the system. It displays the configuration model of the cold source equipment, including various icons, controls, etc. Users can view and operate the cold source equipment through this interface. The operation mode control is a specific control in the configuration model interface, which is used to select and switch the operation mode of the cold source equipment. It is the entry point for users to initiate the operation mode change operation. Each operation mode corresponds to different equipment operation parameters and control logic. After determining the operation mode, the system sends the instructions corresponding to the operation mode to the cold source equipment bound to the configuration model. After receiving the instructions, the equipment adjusts its own operating status, such as changing the cooling capacity, adjusting the fan speed, switching the working mode, etc., to meet the requirements of the selected operation mode.

[0063] Step S40, in response to the second triggering operation of the model icon in the configuration model, displaying the operation data of the cold source equipment corresponding to the model icon.

[0064] During or after the operation of the cold source device according to the specified operation mode, the user performs a second trigger operation on the model icon in the configuration model interface, such as double-clicking or right-clicking. The system will detect this operation and obtain the operation data of the cold source device from the device management module according to the binding relationship between the model icon and the cold source device, including the operating status, temperature, pressure, flow and other key parameters of the device. Then, the obtained operation data of the cold source device is displayed on the interface. The display method is carried out according to the previously set interactive events and display tags, which can be to pop up a dialog box, update the content in a specific data display area, etc., so that the user can intuitively view the current operation status of the cold source device.

[0065] In this embodiment, through the steps of building and configuring the configuration model, equipment binding and interactive settings, operation mode control, and operation data display, the problems of separation of the front-end interface and equipment control and poor interactivity in the traditional cold source system are effectively solved. Users can intuitively build and display the cold source equipment model through a graphical interface to achieve accurate positioning and parameter configuration of the equipment. By directly controlling the equipment and adjusting the parameters in the configuration model interface and obtaining the equipment operation data in real time, flexible control and real-time monitoring of the equipment operation mode are supported, which helps to achieve efficient operation and refined management of the cold source system, enhances the system interactivity, and improves the efficiency of cold source scheduling.

[0066] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. On this basis, step S30 includes steps S31~S33:

[0067] Step S31, in response to a triggering operation of an operation mode control in a configuration model interface, determining an operation mode of a cold source device corresponding to the configuration model.

[0068] The system continuously monitors the status of the operating mode control in the configuration model interface. When the user triggers the control through operations such as mouse clicks and touches, the system detects this event and determines the currently selected mode from the preset operating mode list based on the user's operation on the operating mode control.

[0069] Step S32: when the operation mode of the cold source device corresponding to the configuration model is the first mode, obtaining the energy efficiency range of the started chiller in the cold source device corresponding to the configuration model.

[0070] Optionally, when the operating mode of the cold source device corresponding to the configuration model is the first mode, the return water temperature and supply water temperature of the freezing side of the started chilled water host are collected, the inlet and outlet temperature difference of the chilled water is determined based on the return water temperature and the supply water temperature, and the energy efficiency range of the started chilled water host is determined based on the inlet and outlet temperature difference of the chilled water and the chilled water flow rate.

[0071] It should be noted that the chiller is used to produce low-temperature chilled water to meet the refrigeration needs of buildings or industrial processes. The return water temperature on the chilled side refers to the temperature of the chilled water returning from the terminal equipment to the chiller, and the supply water temperature on the chilled side refers to the temperature of the chilled water output from the chiller to the terminal equipment. The chilled water inlet and outlet temperature difference refers to the difference between the supply water temperature and the return water temperature on the chilled side. The chilled water inlet and outlet temperature difference reflects the amount of heat absorbed by the chilled water in the terminal equipment. The greater the temperature difference, the more heat the chilled water absorbs, and the higher the load of the chiller. The chilled water flow rate refers to the volume flow of chilled water passing through the chiller per unit time. The energy efficiency range refers to the range of the energy efficiency ratio of the chiller under the current operating state. The energy efficiency ratio indicates the cooling capacity that can be provided per unit of energy consumption. The energy efficiency curve is a curve that describes the change relationship of the energy efficiency ratio of the chiller under different load rates.

[0072] Exemplarily, high-precision temperature sensors are installed on the return water pipe on the freezing side and the supply water pipe on the freezing side of the chiller, respectively, to collect the return water temperature T1 and the supply water temperature T2 on the freezing side in real time, and calculate the chilled water inlet and outlet temperature difference ΔT=T2-T1. At the same time, a flow meter is installed on the chilled water pipeline to monitor the flow rate Q of the chilled water in real time. The type of flow meter can be an electromagnetic flow meter, an ultrasonic flow meter, etc., which can be selected according to the actual pipeline conditions and accuracy requirements. According to the collected chilled water temperature difference ΔT and the chilled water flow rate Q, the load of the chiller is calculated, and then the energy efficiency range of the chiller is determined according to the load of the chiller.

[0073] Optionally, a preset energy efficiency curve is obtained, and the load of the started water chiller is determined based on the chilled water inlet and outlet temperature difference and the chilled water flow rate. Based on the load of the started water chiller, the energy efficiency range of the started water chiller is determined in the energy efficiency curve.

[0074] For example, the historical operation data of the chiller at different load rates is collected, and the energy efficiency curve is established using the exponential weighted average method. The energy efficiency curve represents the change of the energy efficiency ratio of the chiller at different load rates. The closer the data is to the current time, the higher the weight is, so as to reflect the current energy efficiency status of the equipment. The energy efficiency curve provided by the equipment manufacturer can also be input into the system.

[0075] According to the current chilled water inlet and outlet temperature difference ΔT and chilled water flow Q, calculate the load P of the chiller (equivalent to the actual cooling capacity): P=Q×ρ×Cp×ΔT. Then, according to the calculated load P of the chiller, determine the load rate of the host. The load rate can be calculated by the following formula: Load rate=P / .in Indicates the rated cooling capacity of the chiller, which can usually be found on the equipment nameplate or technical specifications. The energy efficiency curve provides the energy efficiency ratio value at different load rates. By comparing the measured load of the chiller and the energy efficiency curve, the energy efficiency ratio value of each started chiller can be determined, and then the energy efficiency range value of the started chiller can be determined.

[0076] Step S33, based on the energy efficiency range of the started chillers, determine at least one target chiller among the started chillers and control the target chiller to shut down, or determine at least one target chiller among the unstarted chillers and control the target chiller to start.

[0077] It is understandable that the energy efficiency ratio is an important indicator to measure the performance of the chiller, which indicates the amount of cooling that can be obtained per unit of power consumption. The larger the energy efficiency ratio, the higher the efficiency of the cold source equipment and the more energy-saving it is. Under the same working conditions, the size of the energy efficiency ratio directly reflects the cooling efficiency of the cold source equipment. At the same time, the energy efficiency ratio of the chiller usually changes with the change of the chiller load. Under low load, the energy efficiency ratio of the host is usually low, because the cooling capacity is relatively small at this time, while the energy consumption is relatively high. At this time, you can choose to shut down at least one chiller to reduce the number of inefficient chillers in the cold source equipment, thereby reducing the overall energy consumption. Similarly, when the energy efficiency of all the started chillers is relatively large and they are all in a high-efficiency operation state, you can choose to start a new chiller and distribute the load to the newly started chiller to avoid overloading of some chillers, thereby improving the overall energy efficiency of the cold source equipment.

[0078] Optionally, if the maximum value of the energy efficiency range of the started chilled water hosts is less than the first preset energy efficiency value, and the number of started chilled water hosts is greater than 1, the chilled water host with the smallest rated maximum cooling capacity among the started chilled water hosts is determined as the target chilled water host, and the target chilled water host is controlled to be shut down.

[0079] It should be noted that the rated maximum cooling capacity refers to the maximum cooling capacity that the chiller can provide under the design conditions, and is used to measure the upper limit of the chiller's cooling capacity. In dynamic scheduling, selecting the host with the smallest rated maximum cooling capacity as the target chiller can more finely adjust the system's cooling capacity to avoid over-cooling or energy waste.

[0080] Exemplarily, in this embodiment, assuming that the first preset energy efficiency value is 2.6, the system first monitors the energy efficiency range of the started water chillers in real time, that is, the maximum and minimum values ​​of the energy efficiency ratios of all started hosts. If the maximum value of the energy efficiency range is less than the first preset energy efficiency value of 2.6, this means that the energy efficiency of all started hosts is low. At this time, check the number of started water chillers. If the number is greater than 1, it means that there are multiple water chillers in operation. Among the started water chillers, find the water chiller with the smallest rated maximum cooling capacity by comparing the rated maximum cooling capacity of each water chiller, and use this water chiller with the smallest rated maximum cooling capacity as the target water chiller, send a shutdown command to the target water chiller, and control it to switch from the started state to the closed state.

[0081] Optionally, among the started chillers, by comparing the rated maximum cooling capacity of each chiller, the started chillers can be sorted according to the size of the rated maximum cooling capacity, a preset number of chillers with smaller rated maximum cooling capacity can be selected as the target chiller, and a shutdown command can be sent to the target chiller to control it to switch from the started state to the shut down state.

[0082] When the energy efficiency of all started chillers is low, shutting down the chiller with the smallest rated maximum cooling capacity can concentrate the load on the chiller with relatively higher energy efficiency, utilize energy more efficiently, and improve the overall energy efficiency of the cold source equipment.

[0083] Optionally, if the maximum value of the energy efficiency range of the started water chiller is less than the first preset energy efficiency value, and the number of started water chillers is equal to 1, then the inlet and outlet temperature difference of the started water chiller is obtained; if the inlet and outlet temperature difference of the chilled water is greater than the first preset temperature difference value, and the frequency of the started water chiller is less than the first preset frequency, then the frequency of the water chiller is increased; if the inlet and outlet temperature difference of the chilled water is less than the second preset temperature difference value, and the frequency of the started water chiller is greater than the second preset frequency, then the frequency of the water chiller is reduced, wherein the first preset temperature difference value is greater than the second preset temperature difference value, and the first preset frequency is greater than the second preset frequency.

[0084] It is understandable that the inlet and outlet temperature difference of chilled water can reflect the load change of the cold source equipment. When the inlet and outlet temperature difference of chilled water is large, it means that the load of the chilled water host is high, and the flow rate of chilled water needs to be increased to meet the load demand; when the inlet and outlet temperature difference of chilled water is small, it means that the load of the chilled water host is low, and the flow rate of chilled water can be reduced to save energy. If the inlet and outlet temperature difference of chilled water is large, and the energy efficiency of the started chilled water host is relatively low, and only one chilled water host is running, the chilled water flow rate can be increased by increasing the frequency of the chilled water pump, thereby improving the heat exchange efficiency of the chilled water, so that the started chilled water host can better meet the load demand, avoid overloading the started chilled water host, and improve the overall energy efficiency of the cold source equipment. Similarly, when the inlet and outlet temperature difference of chilled water is small, it means that the load of the chilled water host is low, and the flow rate of chilled water can be reduced to save energy.

[0085] Exemplarily, in this embodiment, assuming that the first preset temperature difference is 5°C and the second preset temperature difference is 3°C, if the system detects that the maximum value of the energy efficiency range of the currently started chiller is less than 2.6, and there is only one started chiller, then the temperature sensors on the return water pipe on the freezing side and the supply water pipe on the freezing side of the chiller are used to obtain the supply water temperature and return water temperature of the chiller on the freezing side, and calculate the chilled water inlet and outlet temperature difference of the chiller. If the chilled water inlet and outlet temperature difference is greater than 5°C, and the frequency of the started chilled water pump is less than the first preset frequency, the frequency of the chilled water pump is increased. If the chilled water inlet and outlet temperature difference is less than 3°C, and the frequency of the started chilled water pump is greater than the second preset frequency, the frequency of the chilled water pump is reduced.

[0086] It should be noted that the first preset temperature difference value, the second preset temperature difference value, the first preset frequency, and the second preset frequency can all be set according to actual conditions.

[0087] Optionally, if the minimum value of the energy efficiency range of the started chiller is greater than a second preset energy efficiency value, the chiller with the smallest rated maximum cooling capacity among the unstarted chillers is determined as the target chiller, and the target chiller is controlled to start, wherein the second preset energy efficiency value is greater than the first preset energy efficiency value.

[0088] Exemplarily, in this embodiment, assuming that the second preset energy efficiency value is 5.1, when the minimum value of the energy efficiency range of the started chilled water hosts is greater than the second preset threshold value, it means that all started chilled water hosts are in a high energy efficiency operation state. At this time, starting the unstarted chilled water hosts can distribute the load more evenly to all hosts, avoiding overload operation of some chilled water hosts, thereby improving the overall energy efficiency of the cold source equipment.

[0089] Optionally, the expected cooling capacity for the day is calculated based on the cooling capacity of the chillers in the same period in history, or the expected cooling capacity for the day is calculated based on the cooling capacity of the chillers on the previous day. When starting an unstarted chiller, the chiller with the smallest rated maximum cooling capacity is controlled to start first. After starting, the cooling capacity of all started chillers is detected. If the cooling capacity of all started chillers is less than the expected cooling capacity for the day, the chiller with the smallest rated maximum cooling capacity that has just been started is shut down, and the chiller with the smallest rated maximum cooling capacity is selected from other unstarted chillers to start, until the cooling capacity of all started chillers is equal to or greater than the expected cooling capacity for the day. Similarly, when the cold source equipment needs to reduce the cooling supply, that is, when the activated chillers need to be shut down, the chiller with the smallest rated maximum cooling capacity will be shut down first. If the cooling capacity of all activated chillers after shutdown is greater than the preset cooling capacity threshold, the chiller with the smallest rated maximum cooling capacity that has just been shut down will be turned on, and the chiller with the smallest rated maximum cooling capacity among the other activated chillers will be shut down. This is because the chiller with the smallest rated maximum cooling capacity has a smaller cooling capacity, which can more finely adjust the overall load of the cold source equipment to avoid excessive increase or decrease in cooling supply.

[0090] Based on the above embodiments of the present application, in the third embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above introduction, and will not be described in detail later. On this basis, step S30 also includes steps S34 to S36:

[0091] Step S34, in response to the triggering operation of the operation mode control in the configuration model interface, determining the operation mode of the cold source device corresponding to the configuration model.

[0092] Step S35, when the operation mode of the cold source device corresponding to the configuration model is the second mode, obtaining the humidity detected by the humidity sensor in the cold source device corresponding to the configuration model.

[0093] Step S36, when the humidity is greater than a preset humidity threshold, controlling the fan in the cold source device to start.

[0094] If the operation mode of the cold source device is the second mode, the system accesses the humidity sensor in the cold source device and reads the current ambient humidity value detected by it. Humidity sensors are usually installed in areas where humidity needs to be monitored, such as refrigeration rooms, air supply ducts, etc., and can monitor humidity changes in the air in real time. The acquired humidity value is compared with a preset humidity threshold. The preset humidity threshold is a reference value set according to actual application scenarios and requirements. When the ambient humidity exceeds the threshold, it may affect the normal operation or cooling effect of the cold source device, and corresponding measures need to be taken. In this embodiment, if the humidity is greater than the preset humidity threshold, the system sends a control instruction to the fan in the cold source device to start it.

[0095] Optionally, step S30 further includes steps S37 to S39:

[0096] Step S37, in response to the triggering operation of the operation mode control in the configuration model interface, determining the operation mode of the cold source device corresponding to the configuration model.

[0097] Step S38, when the operation mode of the cold source device corresponding to the configuration model is the third mode, in response to the icon selection action of any model icon in the configuration model, the target cold source device corresponding to the model icon is determined, and the operation parameter control interface of the target cold source device is displayed.

[0098] Step S39, in response to the configuration action received by the operating parameter control interface of the target cooling source device, determining the operating parameters of the target cooling source device, and controlling the target cooling source device to operate according to the operating parameters.

[0099] In the present embodiment, the third mode refers to a mode that allows the user to perform refined control on a single cold source device. In the third mode, the system monitors the user's click or selection operation on any model icon in the configuration model interface. According to the model icon selected by the user, the system determines the actual cold source device corresponding to the model icon through a preset binding relationship, and uses it as the target cold source device. After that, it pops up or switches to the operating parameter control interface of the target cold source device, which contains adjustable operating parameter setting options for the target cold source device, such as temperature setting, fan speed adjustment, etc. The system waits for the user to perform configuration actions in the operating parameter control interface, such as entering a value in the input box, moving a slider, etc. After the user completes the configuration, the system reads and confirms the operating parameters set by the user, such as setting the temperature to 20 degrees Celsius, etc., and then sends the determined operating parameters to the target cold source device. After receiving the operating parameters, the target cold source device adjusts its own operating state and works according to the new operating parameters. In a complex cold source system, the above mode allows the user to flexibly optimize a single device according to actual conditions without adjusting the parameters of all devices at the same time.

[0100] Optionally, in response to a configuration action received by the operating parameter control interface of the target cold source device, a power-on time and a power-off time of the target cold source device are determined, and the target cold source device is controlled to start at the power-on time and shut down at the power-off time.

[0101] For example, according to the configured startup and shutdown time of each cold source device, the cold source device is automatically controlled to start and stop every day. For example, the automatic startup sequence is: open the cooling butterfly valve, start the cooling water pump (wait for 1 minute), start the cooling tower fan, open the chilled water valve, start the chilled water pump, and start the chilled water host; the automatic shutdown sequence is: shut down the chilled water host, shut down the chilled water pump (wait for 3 minutes), shut down the chilled water valve, shut down the cooling tower fan, shut down the cooling water pump (wait for 3 minutes), and close the cooling butterfly valve.

[0102] Based on the above embodiments of the present application, in the fourth embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above introduction, and will not be described in detail later. Figure 2 , before step S10, steps S50 to S80 are also included:

[0103] Step S50, displaying a configuration model drawing interface, wherein the configuration model drawing interface includes an icon area, a canvas area, and an icon attribute configuration area.

[0104] Step S60, in response to the icon selection action received in the icon area, determining the model icon of the configuration model, and displaying the model icon in the canvas area.

[0105] The configuration model drawing interface is a visual interface for users to create and edit configuration models. It provides the tools and areas required to build configuration models. The icon area displays various available icon resources, from which users can select the required icons to add to the configuration model. The canvas area is the core part of the configuration model drawing interface, where users can place, move, rotate, and other operations on the selected icons to build a complete configuration model.

[0106] For example, the user browses the available icons in the icon area and selects one or more icons by clicking the mouse or other selection methods. The user can move the selected model icons to the canvas area by clicking and dragging the mouse, and move, rotate, etc. these icons in the canvas area to build the required configuration model.

[0107] Step S70: In response to the icon selection action of the model icon in the canvas area, a parameter configuration control corresponding to the model icon is displayed in the icon property configuration area.

[0108] Step S80, in response to the configuration action received by the parameter configuration control corresponding to the model icon, determining the display parameters of the model icon, wherein the display parameters at least include color, size, position and angle.

[0109] When the user selects a model icon in the canvas area, the icon property configuration area will display the parameter configuration options related to the icon, where the user can set the icon's properties in detail. Each model icon represents a graphic symbol of various equipment, components or elements in the cold source system, such as a chiller icon, a fan icon, a valve icon, etc., which is the basic unit for building a configuration model. The parameter configuration control is a specific interactive element in the icon property configuration area that is used to set the model icon properties, such as an input box, a drop-down menu, a slider, a check box, etc. The user enters or selects the corresponding values ​​through these controls to define the display parameters of the model icon. The display parameters determine the visual presentation of the model icon in the canvas area, including color, size, position, and angle. The setting of these parameters helps users to more intuitively understand and distinguish different elements in the configuration model.

[0110] Optionally, in response to the user clicking on the canvas, a canvas setting interface is displayed, where the user can set the canvas size, background image, etc. Text can also be entered in the canvas area, and the position, size, angle, text width, text content, text direction, text color, alignment, etc. of the text can be set.

[0111] Optionally, the cold source dispatching system based on the configuration model can provide a CAD (Computer-Aided Design) drawing file import function. By importing the CAD drawings containing the connection relationship information of the field equipment, physical simulation is performed according to the CAD drawings or the actual connection relationship of the field equipment, and the configuration model is automatically generated in the canvas area.

[0112] For example, refer to Figure 3 , Figure 3 The schematic diagram of the configuration model drawing interface provided for the present embodiment, wherein the left side is the icon area, the middle is the canvas area, and the right side is the icon attribute configuration area. Among them, the icon area is provided with basic element icons, instrument icons, chiller icons and sensor icons. After the user drags the icon to the canvas area, clicking the icon can display the parameter configuration control corresponding to the icon on the right. In this embodiment, the parameter configuration control is set in the "element attribute" area, and the position, size, angle, color, etc. of the icon can be set through the parameter configuration control. In addition to the icon, other elements such as canvas, text and lines in the canvas area can also be configured in the attribute configuration area. After completing the drawing of the configuration model, the model configuration interface corresponding to the model icon can be displayed in the "interaction" area on the right by clicking the model icon, and the model icon can be bound to the cold source equipment, set the interaction event and display the label, etc. in the model configuration interface. Among them, the model icon refers to the icon in the canvas area after completing the drawing of the configuration model.

[0113] For example, Figure 4As shown, Figure 4 The configuration model schematic diagram provided for this embodiment includes two chillers. The left side of the chiller is the cooling side, including 3 cooling water pumps and 2 cooling towers. Each cooling tower has an outdoor temperature sensor outside for measuring the wet bulb temperature of the cooling tower. A cooling tower fan (not shown in the figure) is arranged in the cooling tower. Among them, the cooling water flows out from the water collecting tray of the cooling tower and is transported to the inlet of the cooling water pump through a pipeline. The cooling water pump pressurizes the cooling water so that it has sufficient pressure to enter the chiller. In the chiller, the high-temperature and high-pressure refrigerant gas transfers heat to the cooling water through the condenser tube bundle. The temperature of the cooling water increases after absorbing heat. The high-temperature cooling water after absorbing heat is transported to the cooling tower through a pipeline. After being processed by the cooling tower, the temperature of the cooling water is reduced again and returned to the inlet of the cooling pump through a pipeline to enter the next cycle. The right side of the chiller is the freezing side, including 3 chilled water pumps, 1 fan and 1 water supply manifold. The chiller cools the water to a lower temperature through the refrigeration cycle process, and then transports the low-temperature chilled water to the air-conditioning terminal equipment to achieve the cooling effect. Among them, the chilled water exchanges heat with the indoor air in the air-conditioning terminal equipment, absorbs heat from the air, and its temperature rises. The chilled water after heat exchange flows back to the evaporator of the chiller through the return pipe, and is cooled again, completing a cycle.

[0114] Based on the above embodiments of the present application, in the fifth embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above introduction, and will not be repeated in the following. On this basis, after step S33, the cold source scheduling method based on the configuration model further includes steps S331 to S333:

[0115] Step S331, determining the sum of the chilled water flow rates in all started chillers, and taking the sum of the chilled water flow rates as the current flow rate.

[0116] It is understandable that in the above-mentioned step of dynamically increasing or decreasing the chiller, the cooling supply of the cold source device is adjusted by starting or shutting down the chiller. This method can ensure that the cold source device can meet the load demand while minimizing energy consumption. By adjusting the operating state of the chilled water pump, the chilled water flow in the freezing side circuit can be further optimized to ensure that the chilled water flow matches the demand of the chiller.

[0117] Exemplarily, after controlling the target chiller to switch its on / off state, the ultrasonic flowmeter or electromagnetic flowmeter installed on the freezing side water supply pipe and the freezing side water return pipe is used to collect the chilled water flow of each started chiller in real time, and the chilled water flow of all started chillers is added together to obtain the total chilled water flow of the current cold source equipment, that is, the current flow.

[0118] Step S332: If the target chilled water host is a started chilled water host, the sum of the rated minimum chilled water flow rates of all started chilled water hosts is obtained. When the sum of the rated minimum chilled water flow rates is less than the current flow rate, the chilled water pump with the shortest cumulative start-up time among the started chilled water pumps is determined as the target chilled water pump, and the target chilled water pump is controlled to be shut down.

[0119] Step S333: If the target chilled water host is an unstarted chilled water host, the sum of the rated minimum chilled water flow rates of all started chilled water hosts is obtained. When the product of the sum of the rated minimum chilled water flow rates and the preset coefficient is greater than the current flow rate, the chilled water pump with the shortest cumulative start-up time among the unstarted chilled water pumps is determined as the target chilled water pump, and the target chilled water pump is controlled to start.

[0120] It is understandable that each chiller has a rated minimum chilled water flow rate, which is the minimum chilled water flow rate required for the normal operation of the chiller, and is determined by the equipment manufacturer based on the design parameters of the chiller. When the system controls the started chiller to shut down, it obtains the rated minimum chilled water flow rates of all started chillers, and adds them together to obtain the sum of the rated minimum chilled water flow rates. If the sum of the rated minimum chilled water flow rates is less than the current flow rate, it means that the current chilled water flow rate is excessive and the chilled water flow rate needs to be reduced. At this time, the system selects the chilled water pump with the shortest cumulative start-up time from all started chilled water pumps as the target chilled water pump, and sends a shutdown command to the target chilled water pump, switching it from the start state to the shutdown state, ensuring that the chilled water flow rate matches the actual needs of the chiller, and improving the overall operating efficiency and stability of the cold source equipment.

[0121] Similarly, when the system controls the startup of the unstarted chilled water host, the rated minimum chilled water flow of all started chilled water hosts is obtained, and they are added together to obtain the sum of the rated minimum chilled water flow. If the product of the sum of the rated minimum chilled water flow and the preset coefficient is less than the current flow, it means that the current chilled water flow is insufficient and the flow needs to be increased. At this time, the system selects the chilled water pump with the shortest cumulative startup time from all unstarted chilled water pumps as the target chilled water pump, and sends a shutdown command to the target chilled water pump to switch it from the closed state to the started state, wherein the preset coefficient is a parameter set by the system, which is used to adjust or calibrate certain calculation results to adapt to different operating conditions. In this step, the preset coefficient is used to adjust the sum of the rated minimum chilled water flow to determine whether it is necessary to add a chilled water pump. The preset coefficient can be adjusted according to the actual operating conditions.

[0122] Optionally, after the target chilled water pump is controlled to be shut down or started, the cooling side supply water temperature, cooling side return water temperature and cooling tower wet bulb temperature in the started chilled water host are collected. The cooling water inlet and outlet temperature difference is determined based on the cooling side supply water temperature and the cooling side return water temperature, and the cooling system approximation is determined based on the cooling side supply water temperature and the cooling tower wet bulb temperature. Based on the cooling system approximation, at least one target cooling tower fan is determined among the unstarted cooling tower fans, and the target cooling tower fan is controlled to be started, or at least one target cooling tower fan is determined among the started cooling tower fans and the target cooling tower fan is controlled to be shut down. Based on the cooling water inlet and outlet temperature difference, at least one target cooling water pump is determined among the unstarted cooling water pumps and the target cooling water pump is controlled to be started, or at least one target cooling water pump is determined among the started cooling water pumps and the target cooling water pump is controlled to be shut down.

[0123] It should be noted that the wet-bulb temperature refers to the lowest temperature that water can reach through evaporative cooling under specific environmental conditions. The temperature-sensing part of the wet-bulb temperature sensor is wrapped in wet gauze. When air flows through, water evaporates and takes away heat, causing the temperature to drop. The final stabilized temperature is the wet-bulb temperature.

[0124] Exemplarily, the cooling side water supply temperature and the cooling side water return temperature are collected in real time by installing temperature sensors on the cooling water supply pipe and the cooling water return pipe. At the same time, the current wet-bulb temperature is collected in real time by installing a wet-bulb temperature sensor near the cooling tower. Among them, the cooling water inlet and outlet temperature difference = cooling side return water temperature - cooling side supply water temperature. The cooling water inlet and outlet temperature difference reflects the actual heat exchange effect of the cooling water in the cooling system. The greater the temperature difference, the more heat the cooling water takes away. Cooling system approximation = cooling side water supply temperature - cooling tower wet-bulb temperature. The cooling system approximation reflects the degree of closeness between the cooling tower outlet water temperature and the cooling tower wet-bulb temperature. The smaller the cooling system approximation, the better the cooling effect of the cooling tower.

[0125] It can be understood that when the outlet water temperature of the cooling tower, that is, the cooling side water supply temperature is closer to the wet bulb temperature of the cooling tower, the cooling effect of the cooling tower is better. Therefore, the cooling efficiency of the cooling tower can be improved by dynamically adjusting the operating state of the cooling tower fan to ensure that the outlet water temperature of the cooling tower is close to the wet bulb temperature of the cooling tower.

[0126] Specifically, if the cooling system approximation is greater than the first preset approximation and the number of cooling tower fans that have been started is less than 1, the cooling tower fan with the shortest cumulative start-up time among the cooling tower fans that have not been started is determined as the target cooling tower fan, and the target cooling tower fan is controlled to start. If the cooling system approximation is less than the second preset approximation and the number of cooling tower fans that have been started is greater than 1, the cooling tower fan with the shortest cumulative start-up time among the cooling tower fans that have been started is determined as the target cooling tower fan, and the target cooling tower fan is controlled to be turned off, wherein the first preset approximation is greater than the second preset approximation.

[0127] Specifically, if the cooling water inlet and outlet temperature difference is greater than the third preset temperature difference value and the frequency of the started cooling water pump is greater than or equal to the third frequency threshold, the cooling water pump with the shortest cumulative start-up time among the unstarted cooling water pumps is determined as the target cooling water pump, and the target cooling water pump is controlled to start. If the cooling water inlet and outlet temperature difference is less than the fourth preset temperature difference value and the number of started cooling water pumps is greater than 1, the cooling water pump with the shortest cumulative start-up time among the started cooling water pumps is determined as the target cooling water pump, and the target cooling water pump is controlled to be turned off, wherein the third preset temperature difference value is greater than the fourth preset temperature difference value.

[0128] Optionally, the cold source scheduling system based on the configuration model in the embodiment of the present application may include a device management module, a configuration model configuration module, a configuration management module, a system configuration module and a dynamic scheduling module.

[0129] The equipment management module is responsible for connecting the cold source equipment at the cold station site to the system through a direct connection, and configuring the equipment parameter fields such as the first preset energy efficiency value, the second preset energy efficiency value, the first preset temperature difference value, the second preset temperature difference value, the third preset temperature difference value, the fourth preset temperature difference value, the first preset approximation degree, the second preset approximation degree, the first frequency threshold, the second frequency threshold, the third frequency threshold, the fourth frequency threshold, etc. according to the monitoring data, as well as realizing real-time monitoring of the cold source equipment or issuing control instructions.

[0130] The configuration model configuration module provides a configuration model configuration interface, supports the import of CAD drawing files and manual drawing of configuration models, realizes physical simulation of configuration models, and restores the connection relationship of on-site equipment. Users can use the configuration model configuration module to set the style of the configuration model, bind devices, set interactive events and display labels, publish and update the configuration model, etc.

[0131] The configuration management module is used to manage the configured configuration models and provide viewing and interaction functions for the configuration models. A single device can be controlled through the configuration model. By clicking the device icon of the configuration model, the selected single device can be turned on and off and the operating parameters can be adjusted according to actual needs.

[0132] The system configuration module allows users to set the system automatic operation time and expected cooling capacity according to different seasons and months.
