[0061] See also Figure 1 As shown, Figure 1The structure diagram of an air conditioner energy efficiency monitoring system provided by an embodiment of the present specification is shown. The air conditioner energy efficiency monitoring system may include a user terminal 100 and an energy efficiency server 200;

[0062] The user terminal 100 is used to generate an energy efficiency query request according to the query service type selected by the user for the target air-conditioning system, and send the energy efficiency query request to the energy efficiency server 200;

[0063] The energy efficiency server 200 is used to obtain the performance data of the target air-conditioning system according to the energy efficiency query request, determine the index value of each energy efficiency index in the energy efficiency standard pre-configured for the target air-conditioning system by using the performance data, and return a query response to the user terminal 100; the query response includes the index value of each energy efficiency index and the key scale of each energy efficiency index in the energy efficiency standard, the energy efficiency index reflects the energy efficiency level of different components of the air-conditioning system, and the key scale of the scale is used to indicate the energy efficiency level division boundary of the energy efficiency index;

[0064] The user terminal 100 is also used to display the query response.

[0065] The scheme of the embodiment of the present specification is applied, by providing different query service types of the air-conditioning system for the user to choose from on the user side, sending an energy efficiency query request to the energy efficiency server according to the query service type selected by the user, and the energy efficiency server calculates the index value of each energy efficiency index in the energy efficiency standard pre-configured for the air-conditioning system by obtaining the performance data of the air-conditioning system, and then returns the query response to the user side according to the index value and the key scale of the scale of each energy efficiency index in the energy efficiency standard and displays it to the user, so as to meet the user's need to view the energy efficiency of the air-conditioning system. Since each energy efficiency index reflects the energy efficiency level of different components of the air-conditioning system, the user can intuitively perceive the energy efficiency level of different components of the air-conditioning system, and since the key scale of the scale of each energy efficiency index in the pre-configured energy efficiency standard is used to indicate the boundary of energy efficiency level division, the quantitative standard of energy efficiency index can be provided to the user, so that the user can intuitively understand the energy efficiency of the air-conditioning system.

[0066] In the above system embodiment, the energy efficiency server 200 provides backend services for the user terminal 100, which can be implemented as a distributed server cluster composed of multiple servers, or as a single server. The server can also be a server of a distributed system, or a server combined with a blockchain, and of course it can also be a cloud server for basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content distribution networks (CDN, Content Delivery Network) and big data and artificial intelligence platforms, or an intelligent cloud computing server or intelligent cloud host with artificial intelligence technology.

[0067] The user end 100 serves as the front end of the energy efficiency server 200, which can be a browser, an APP (Application), or a web application such as an H5 (Hyper Text Markup Language 5, Hypertext Markup Language Version 5) application, or a light application (also known as a mini-program, a lightweight application) or a cloud application, etc.

[0068] It can be understood that the air conditioning energy efficiency monitoring system described in the embodiment of the present application is to more clearly illustrate the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided in the embodiment of the present application. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0069] Figure 2 This is a schematic diagram of an embodiment of an air conditioner energy efficiency monitoring method according to an exemplary embodiment of the present application. The air conditioner energy efficiency monitoring method is based on the above Figure 1 The energy efficiency server 200 in the air conditioning energy efficiency monitoring system shown is the execution subject. Figure 2 As shown, the air conditioning energy efficiency monitoring method comprises the following steps:

[0070] Step 201: acquiring performance data of a target air conditioning system according to an energy efficiency query request sent by a user terminal;

[0071] Step 202: using the performance data, determining the index value of each energy efficiency index in the energy efficiency standard pre-configured for the target air-conditioning system, wherein each energy efficiency index reflects the energy efficiency level of different components of the air-conditioning system;

[0072] Step 203: Return a query response to the user end, the query response including the index value of each energy efficiency index and the key scale of each energy efficiency index in the energy efficiency standard, the key scale of the scale is used to indicate the energy efficiency level division boundary of the energy efficiency index.

[0073] The energy efficiency query request can be understood as a user-triggered air conditioning system energy efficiency query request, which can include basic information of the target air conditioning system, the query service type selected by the user, project identification, query time and other request parameters. Among them, the basic information can be the name and type of the air conditioning system, the query service type can include energy efficiency real-time query type, daily energy efficiency query type, specified time range query type, etc. The project identification refers to the code of the air conditioning system energy efficiency project.

[0074] The target air conditioning system can be understood as an air conditioning system for which the user has management authority, and its associated component equipment components may include at least one of a host, a chiller, a refrigeration water pump, a cooling water pump, a cooling tower, and a terminal device.

[0075] Performance data can be understood as data processed from the equipment point data reported by the target air-conditioning system. The performance data can at least include the cooling data of the air-conditioning system and the energy consumption data of different components of the air-conditioning system. The cooling data indicates the cooling capacity provided by the air-conditioning system, and the unit can be KW. The energy consumption data indicates the electric energy consumed during the operation of the air-conditioning system, and the unit can be KWh. Generally, the main energy-consuming equipment components of the air-conditioning system include the main unit, chiller, chilled water pump, cooling water pump, cooling tower and terminal equipment. Therefore, the energy consumption data can include the energy consumption data of different components of the air-conditioning system.

[0076] The energy efficiency standard is a unified energy efficiency scale configured for the target air-conditioning system. The energy efficiency standard is used to provide a quantitative standard for energy efficiency indicators, and it has a corresponding relationship with the basic information of the target air-conditioning system. The energy efficiency standard includes various energy efficiency indicators configured by the user and the key scale of each energy efficiency indicator. Among them, each energy efficiency indicator reflects the energy efficiency level of a component in the air-conditioning system, so each energy efficiency indicator can reflect the energy efficiency level of different components of the air-conditioning system. Since the key scale of the scale is used to indicate the energy efficiency level division boundary of the energy efficiency indicator, the key scale of the scale can provide a unified quantitative standard for the air-conditioning system, and the user can understand the energy efficiency level of different values ​​of the energy efficiency indicator.

[0077] For example, assuming that the energy efficiency levels of the energy efficiency index are divided into four types: poor, general, good, and excellent, then the division of energy efficiency levels can be achieved using five key scales. These five key scales include the starting scale, the boundary scale between poor and general, the boundary scale between general and good, and the boundary scale between good and excellent.

[0078] It is worth explaining here that due to certain differences between different air-conditioning systems, the energy efficiency standards configured for different air-conditioning systems are also different. For example, different air-conditioning systems may apply different energy efficiency indicators, or different air-conditioning systems may apply the same energy efficiency indicator, but the key scales of the scale configured for the energy efficiency indicator are different.

[0079] Exemplarily, the energy efficiency index includes at least one of the energy efficiency of the air conditioning system, the energy efficiency of the refrigeration room system, the energy efficiency of the host, the energy efficiency of the chilled water delivery, the energy efficiency of the cooling water delivery, the energy efficiency of the cooling tower delivery, and the comprehensive cooling energy efficiency of the electric cooling source. Among them, the energy efficiency of the air conditioning system can reflect the comprehensive energy efficiency level of the air conditioning system, the energy efficiency of the refrigeration room system can reflect the energy efficiency level of the refrigeration room system in the air conditioning system, and the refrigeration room system usually includes equipment components such as the host, the refrigeration pump, the secondary pump, the secondary pump, the cooling pump, and the cooling tower. The host energy efficiency can reflect the energy efficiency level of the host equipment components in the air conditioning system, the chilled water delivery energy efficiency can reflect the comprehensive energy efficiency level of the refrigeration pump, the secondary pump, and the secondary pump. The cooling water delivery energy efficiency can reflect the energy efficiency level of the cooling pump, the cooling tower delivery energy efficiency can reflect the energy efficiency level of the cooling tower, and the comprehensive cooling energy efficiency of the electric cooling source can reflect the comprehensive energy efficiency level of the host, the cooling pump, the cooling tower, and the comprehensive cooling energy efficiency of the electric cooling source.

[0080] The query response can be understood as the query result of the energy efficiency query request fed back to the user.

[0081] At this point, the above Figure 2 The air conditioning energy efficiency monitoring process shown in the figure, when receiving the energy efficiency query request from the user end, obtains the performance data of the target air conditioning system, and uses the performance data to calculate the index value of each energy efficiency index in the energy efficiency standard pre-configured for the air conditioning system, and then returns the query response to the user end according to the index value and the key scale of the scale of each energy efficiency index in the energy efficiency standard and displays it to the user, so as to meet the user's needs to view the energy efficiency of the air conditioning system. Since each energy efficiency index reflects the energy efficiency level of different components of the air conditioning system, the user can intuitively perceive the energy efficiency level of different components of the air conditioning system, and since the key scale of the scale of each energy efficiency index in the pre-configured energy efficiency standard is used to indicate the boundary of energy efficiency level division, it can provide users with quantitative standards of energy efficiency indicators, so that users can intuitively understand the energy efficiency of the air conditioning system.

[0082] In some embodiments of the present application, before executing step 202, the method further includes:

[0083] In response to a standard configuration request for a target air-conditioning system sent by a user terminal, a configurable energy efficiency index is obtained, as well as a scale reference scale corresponding to the energy efficiency index under different operating levels, and the energy efficiency index and the scale reference scale corresponding to the energy efficiency index under different operating levels are returned to the user terminal, and then the energy efficiency standard carried by the configuration submission request sent by the user terminal is stored, the energy efficiency standard including the energy efficiency index selected by the user and the scale key scale corresponding to the energy efficiency index under different operating levels, and the scale key scale is set according to the scale reference scale.

[0084] The standard configuration request can be understood as a user-triggered request for configuring energy efficiency standards for the air-conditioning system. The standard configuration request may include request parameters such as basic information of the target air-conditioning system, project identification, and configuration time.

[0085] The configurable energy efficiency indicators can be understood as all indicator items for which the energy efficiency server can provide computing logic.

[0086] The above-mentioned working condition level may include at least one of the hourly working condition level and the daily working condition level. By distinguishing the working condition levels, the energy efficiency of the air-conditioning system can be reasonably measured. In other words, the energy efficiency standards that the air-conditioning system should achieve under different working condition levels are different. It is unreasonable to require daily or hourly energy efficiency with the energy efficiency standard of the whole year. Therefore, a scale reference scale can be used to distinguish different working condition levels for energy efficiency indicators.

[0087] The ruler reference scale can be understood as the reference value of the energy efficiency level division boundary provided by the energy efficiency server for the energy efficiency index. The ruler reference scale can provide users with guidance for setting the ruler key scale. It is worth noting here that the ruler key scale of the energy efficiency index can be consistent with the ruler reference scale or inconsistent.

[0088] The configuration submission request can be understood as a request for submitting energy efficiency standards triggered after the user completes the standard configuration. In addition to the relevant parameters of the energy efficiency standards, the configuration submission request can also include basic information of the target air-conditioning system, setting mode of the energy efficiency standards, etc.

[0089] In this embodiment, when configuring the energy efficiency standard, the configurable energy efficiency index and the scale reference scale corresponding to the energy efficiency index under different operating levels are returned to the user end, so that the user can customize the required energy efficiency index for the target air-conditioning system according to different operating levels, and the scale reference scale can also provide the user with guidance on setting the key scales.

[0090] In some embodiments of the present application, the reference scales for obtaining the energy efficiency indicators corresponding to different operating levels may include:

[0091] The regional information of the target air-conditioning system is obtained, and the reference scale corresponding to the energy efficiency index under different operating levels is predicted based on the historical energy consumption data and historical cooling capacity data of the air-conditioning system in the area indicated by the regional information.

[0092] The regional information refers to the geographical area where the air conditioning system is installed. Generally, the climates in different geographical areas are quite different, and the requirements for the cooling / heating capacity of the air conditioning system are different, so the energy consumption data and cooling data generated by the air conditioning system are also quite different.

[0093] Regarding the prediction implementation method of the scale reference scale, a simulation model of the air-conditioning system can be used to dynamically predict and output the scale reference scale under different operating conditions based on the input historical energy consumption data and historical cooling data. The historical energy consumption data and historical cooling data can also be input into a trained neural network model to dynamically predict and output the scale reference scale under different operating conditions. This application does not make any specific limitations on the prediction implementation of the scale reference scale.

[0094] In this embodiment, by using the historical energy consumption data and historical cooling capacity data of the air-conditioning system in the same region as the target air-conditioning system, the scale reference scale corresponding to the energy efficiency index under different operating levels is predicted, thereby ensuring the accuracy and real-time performance of the scale reference scale provided for the target air-conditioning system.

[0095] In other embodiments of the present application, obtaining the scale reference scale corresponding to the energy efficiency index under different operating levels may also include:

[0096] The default value of the scale under different working conditions pre-stored for the energy efficiency indicator is obtained, and the default value of the scale is used as a reference scale of the scale.

[0097] In this embodiment, the default value of the scale can be a value pre-entered into the energy efficiency server for each energy efficiency indicator under different operating levels in combination with the current national or local graded energy efficiency evaluation standards. The default value of the scale can reflect the comprehensive energy efficiency grade evaluation of the air-conditioning system, so as to provide users with guidance on setting key scale scales.

[0098] In other embodiments of the present application, obtaining the scale reference scale corresponding to the energy efficiency index under different operating levels may also include:

[0099] A reference scale of the energy efficiency index is obtained according to operating parameters of the target air-conditioning system, wherein the operating parameters include at least one of building environment, indoor demand, control mode, and equipment performance.

[0100] Among them, the building environment can be parameters such as the building's structure, thermal insulation performance, window type and orientation; the indoor demand can be parameters such as the temperature and humidity requirements of different spaces, usage functions, etc.; the control method can be parameters such as intelligent temperature control or user temperature control; and the equipment performance can be parameters such as the energy efficiency ratio of different components and equipment in the air-conditioning system under different loads.

[0101] Exemplarily, a simulation model of the air-conditioning system may be used to predict the reference scale of the output energy efficiency index according to the input operating parameters.

[0102] In some embodiments of the present application, in step 201, obtaining performance data of a target air conditioning system according to an energy efficiency query request sent by a user terminal includes:

[0103] The query time range is determined according to the query service type carried in the energy efficiency query request, and the performance data of the target air-conditioning system within the query time range is obtained.

[0104] The query service type can be understood as a specific query service provided by the air-conditioning system energy efficiency monitoring project for users to choose. The query service type can be one of the energy efficiency real-time query type, daily energy efficiency query type, and specified time range query type.

[0105] Exemplarily, when the query service type is the real-time energy efficiency query type, the query time range can be defined as the time when the performance data of the air-conditioning system was last recorded, that is, the query time carried by the energy efficiency query request. When the query service type is the daily energy efficiency query type, the query time range can be a specific date. When the query service type is the specified time range query type, the query time range can be the user-specified time range carried by the energy efficiency query request.

[0106] The performance data at least includes the cooling data of the target air conditioning system and the energy consumption data of at least one component in the target air conditioning system. The air conditioning system is provided with a data center, which stores the equipment point data reported by the air conditioning system, processes these equipment point data to form the cooling data and energy consumption data of the air conditioning system and stores them in the data processing table. Based on this, the request parameters and query time range of the energy efficiency query request are encapsulated and the query service interface of the data center is called to obtain the performance data returned by the data center.

[0107] Exemplarily, the cooling data can be the accumulated cooling capacity reported by the chilled water main every 10 minutes to form a sub-incremental table and a daily incremental table reported each time, and the energy consumption data can be the active power reported by the smart meters of each component every 10 minutes to form a sub-incremental table and a daily incremental table reported each time.

[0108] Based on this, if the query business type is the real-time energy efficiency query type, then what is obtained is the cooling data of the sub-incremental table formed by the most recent processing and the energy consumption data of each component; if the query business type is the daily energy efficiency query type, then what is obtained is the cooling data of the daily incremental table corresponding to the query date and the energy consumption data of each component; if the query business type is the specified time range query type, then what is obtained is the cooling data of the daily incremental table corresponding to the time range specified by the user and the energy consumption data of each component.

[0109] In this embodiment, by determining the query time range according to the query service type carried in the energy efficiency query request, the performance data of the target air-conditioning system within a certain time range is obtained instead of all the performance data of the air-conditioning system, thereby reducing unnecessary data volume.

[0110] In some embodiments of the present application, using performance data for step 202 to determine the index value of each energy efficiency index in the energy efficiency standard pre-configured for the target air-conditioning system may include: for each energy efficiency index, substituting the data required by the calculation formula of the energy efficiency index in the performance data into the calculation formula, so as to calculate the index value of the energy efficiency index.

[0111] As mentioned above, the performance data at least includes cooling capacity data and energy consumption data of each component.

[0112] The calculation formula for the energy efficiency index of the air conditioning system is as follows:

[0113] Air conditioning system energy efficiency = cooling capacity / (energy consumption of refrigeration room system + energy consumption of terminal equipment).

[0114] The calculation formula for the energy efficiency of the refrigeration room system is as follows:

[0115] Refrigeration room system energy efficiency = cooling capacity / refrigeration room system energy consumption, where the refrigeration room system energy consumption = main unit energy consumption + refrigeration pump energy consumption + secondary pump energy consumption + secondary pump energy consumption + cooling pump energy consumption + cooling tower energy consumption.

[0116] The calculation formula for the host energy efficiency is as follows:

[0117] Host energy efficiency = cooling capacity / host energy consumption.

[0118] The calculation formula for the energy efficiency index of chilled water transportation energy efficiency is as follows:

[0119] Chilled water transportation energy efficiency = cooling capacity / (energy consumption of refrigeration pump + energy consumption of secondary pump + energy consumption of secondary pump).

[0120] The calculation formula for the energy efficiency indicator of cooling water transportation energy efficiency is as follows:

[0121] Cooling water transport energy efficiency = (cooling capacity + energy consumption of the main unit) / energy consumption of the cooling pump.

[0122] The calculation formula for the energy efficiency index of cooling tower transmission energy efficiency is as follows:

[0123] Cooling tower transmission energy efficiency = (cooling capacity + host energy consumption) / cooling tower energy consumption.

[0124] The calculation formula for the comprehensive refrigeration energy efficiency of the electric cooling source is as follows:

[0125] Comprehensive refrigeration energy efficiency of electric cooling source = cooling capacity / energy consumption of main unit + energy consumption of cooling pump + energy consumption of cooling tower).

[0126] In some embodiments of the present application, returning a query response to the user terminal in step 203 includes:

[0127] Determine the interface parameter structure corresponding to the query service type in the energy efficiency query request, and determine the target operating level applicable to the query service type, and then encapsulate the indicator values ​​of each energy efficiency indicator and the scale key scales of each energy efficiency indicator under the target operating level in the energy efficiency standard according to the interface parameter structure to generate a query response, and return the query response to the user end.

[0128] The interface parameter structure can be understood as the parameter composition format of the query result interface corresponding to the query business type. Different query business types have different corresponding parameter composition structures due to different display styles of the query result interface.

[0129] Different query business types are applicable to different operating conditions. As mentioned above, the query business types may include real-time energy efficiency query type, daily energy efficiency query type, specified time range query type, etc. The real-time energy efficiency query type is applicable to the hourly operating condition level, so the hourly operating condition level scale key scale is used to measure the air conditioner energy efficiency. The daily energy efficiency query type and the specified time range query type are applicable to the daily operating condition level, so the daily operating condition level scale key scale is used to measure the air conditioner energy efficiency.

[0130] In this embodiment, by determining the target operating level applicable to the query business type, the indicator value of each energy efficiency indicator and the corresponding scale key scale under the target operating level are encapsulated according to the interface parameter structure corresponding to the query business type to obtain a query response returned to the user end, so that the user end can directly parse the encapsulated interface parameter structure to display the query results.

[0131] In the above Figure 2 Based on the embodiment shown, Figure 3 This is a schematic diagram of an embodiment of another air conditioner energy efficiency monitoring method according to an exemplary embodiment of the present application. The air conditioner energy efficiency monitoring method is based on the above Figure 1 The user end 100 in the air conditioning energy efficiency monitoring system shown is the execution subject. Figure 3 As shown, the air conditioning energy efficiency monitoring method comprises the following steps:

[0132] Step 301: Generate an energy efficiency query request according to the query service type selected by the user for the target air conditioning system;

[0133] Step 302: Send the energy efficiency query request to the energy efficiency server;

[0134] Step 303: Display the query response returned by the energy efficiency server; the query response is generated by the energy efficiency server based on the indicator values ​​of various energy efficiency indicators and the key scales of the scales of various energy efficiency indicators determined according to the performance data of the target air-conditioning system, and the various energy efficiency indicators and the key scales of the scales of various energy efficiency indicators are included in the energy efficiency standards pre-configured for the target air-conditioning system.

[0135] The query service type is a specific energy efficiency query service selected by the user, for example, it may be one of the energy efficiency real-time query type, the daily energy efficiency query type, and the specified time range query type.

[0136] The request parameters of the energy efficiency query request may include the basic information of the target air-conditioning system, project identification, query time, etc. in addition to the query service type selected by the user.

[0137] The query response can be regarded as the query result returned for the energy efficiency query request. When the user selects different query service types, the display interface style of the corresponding query response is different.

[0138] For example, Figure 4 As shown in the figure, it is the display interface of the query result corresponding to the energy efficiency real-time query type. The key scales and index values ​​of each energy efficiency index are displayed in the instrument type style, and different styles of line segments are used to represent different energy efficiency levels. Figure 4 It can be seen that the index value of each energy efficiency index represents the current real-time energy efficiency level of the air-conditioning system. The energy efficiency level of the real-time energy efficiency can be intuitively perceived through the pointer position and displayed index value on the instrument.

[0139] like Figure 5 As shown in the figure, the query result display interface corresponding to the daily energy efficiency query type, the key scales and index values ​​of each energy efficiency index are displayed in a ruler style, and different styles of line segments are used to represent different energy efficiency levels. Figure 5 It can be seen that the index values ​​of various energy efficiency indicators represent the energy efficiency level of the air-conditioning system on July 2, 2024. The index values ​​displayed on the scale can be used to intuitively perceive the energy efficiency level of the real-time energy efficiency.

[0140] like Figure 6 As shown in the figure, the query result display interface corresponding to the query type of the specified time range is shown. The key scales and index values ​​of each energy efficiency index are displayed in a ruler style. Different styles of line segments are used to represent different energy efficiency levels. Figure 6 It can be seen that the index value of each energy efficiency index represents the cumulative energy efficiency level of the air-conditioning system within a specified time range. The index value displayed on the scale can intuitively perceive the energy efficiency level of the real-time energy efficiency, and Figure 6 The standard value of each energy efficiency indicator is also displayed. The standard value is the boundary scale between good and excellent and is a key scale. Users can intuitively understand the gap with the excellent energy efficiency level through the displayed indicator value and standard value.

[0141] The present application embodiments and the above Figure 2The embodiments shown are based on the same inventive concept. The meanings of the related terms in steps 301 to 303 can be found in the above Figure 2 The relevant description in the illustrated embodiment will not be repeated here.

[0142] At this point, the above Figure 3 The air conditioning energy efficiency monitoring process shown in the figure provides different query service types of the air conditioning system for the user to choose from on the user side, sends an energy efficiency query request to the energy efficiency server according to the query service type selected by the user, and the energy efficiency server generates a query response based on the indicator values ​​of various energy efficiency indicators and the scale key scales of various energy efficiency indicators determined according to the performance data of the target air conditioning system. The user side can display the query response returned by the energy efficiency server to meet the user's need to view the operating energy efficiency of the air conditioning system.

[0143] In some embodiments of the present application, before executing step 301, a process of configuring an energy efficiency standard for the target air conditioning system may also be included:

[0144] The standard configuration request triggered by the user for the target air-conditioning system is sent to the energy efficiency server, and the configurable energy efficiency indicators of the target air-conditioning system and the scale reference scales corresponding to the energy efficiency indicators returned by the energy efficiency server are displayed. In response to the standard submission instruction triggered by the user, the energy efficiency indicator selected by the user and the key scale of the scale set for the selected energy efficiency indicator are used as the energy efficiency standard of the target air-conditioning system, and a configuration submission request containing the energy efficiency standard is sent to the energy efficiency server.

[0145] The standard configuration request may be understood as a request for a standard configuration interface of the air conditioning system.

[0146] For example, Figure 7 In the standard configuration interface shown, the user needs to enter the system name and system type of the target air-conditioning system, and can also select the setting mode of the energy efficiency standard. For the "standard mode", the user cannot change the scale reference scale of the energy efficiency index, that is, when submitting, the scale reference scale is directly used as the scale key scale. For the "custom mode", the user can change the scale reference scale of the energy efficiency index, that is, when submitting, the value changed by the user is used as the scale key scale, and the user can enable or disable the energy efficiency index in the configurable energy efficiency index. The standard submission instruction is triggered after the user clicks the "Confirm" button.

[0147] In this embodiment, when performing energy efficiency standard configuration, a standard configuration request is initiated to the energy efficiency server so that the energy efficiency server returns and displays the configurable energy efficiency indicators and the scale reference scale corresponding to the energy efficiency indicators, so that the user can customize the required energy efficiency indicators for the target air-conditioning system for configuration, and the scale reference scale can also provide the user with guidance on setting the key scales.

[0148] Based on the above Figures 1 to 3 Based on the embodiment shown, Figure 8 This is a standard configuration interaction flow chart shown in accordance with an exemplary embodiment of the present application. Figure 8 In the process, the interaction between the energy efficiency server and the user end is involved. The energy efficiency monitoring service provided by the energy efficiency server is divided into three layers: control layer, service layer and data access layer, so as to separate the back-end user requests and business logic, and improve the maintainability and scalability of the code.

[0149] like Figure 8 As shown in the figure, the interaction process of the standard configuration includes:

[0150] 1) The user terminal initiates a standard configuration request to the energy efficiency server;

[0151] 2) The control layer of the energy efficiency server forwards the standard configuration request to the service layer, and the service layer returns the configurable energy efficiency index and the scale reference scale corresponding to the energy efficiency index to the user end, and the user end displays the standard configuration interface. In the standard configuration interface, users are supported to enable or disable energy efficiency indicators according to their needs, and users are supported to select standard mode and custom mode. After the user completes the required fields in the standard configuration interface, click Confirm to trigger the standard submission instruction;

[0152] 2) The user end submits the energy efficiency index enabled by the user and the key scale set for the energy efficiency index as the configured energy efficiency standard to the control layer in the form of a configuration submission request according to the standard submission instruction, and the control layer passes the configuration submission request to the service layer;

[0153] 3) The service layer encapsulates the basic information of the air-conditioning system, the relationship between the basic information and the energy efficiency standard, and the energy efficiency index data information of the energy efficiency standard according to the parameters of the configuration submission request, and calls the interface of the data access layer to record it in the database;

[0154] 6) When the service layer completes step 3, if there is an exception, the execution will be interrupted and the exception information will be encapsulated and returned to the user end. If there is no exception, the encapsulation success information will be returned to the user end.

[0155] 7) After receiving the exception information or success information, the client renders it on the page, and the configuration process ends.

[0156] Based on the above embodiments, Fig. 9 This is an energy efficiency query interaction flow chart shown in accordance with an exemplary embodiment of the present application, such as Fig. 9 As shown in the figure, the interactive process of energy efficiency query includes:

[0157] 1) The user terminal checks the system energy efficiency through service entrances such as energy efficiency real-time query type, daily energy efficiency query type, and specified time range query type to initiate an energy efficiency query request to the energy efficiency server;

[0158] 2) The control layer of the energy efficiency server receives the energy efficiency query request and passes it to the service layer;

[0159] 3) The service layer calls the query service interface of the data center of the air conditioning system according to the parameters of the energy efficiency query request to obtain the performance data of the air conditioning system;

[0160] 4) The data center constructs SQL (Structured Query Language) statements according to the parameters of the energy efficiency query request, and executes the SQL statements to obtain the cooling data and energy consumption data of the air-conditioning system, encapsulates the performance data and returns it to the service layer;

[0161] 5) The service layer calculates the index value of each energy efficiency indicator in the energy efficiency standard pre-configured for the air-conditioning system based on the received cooling data and energy consumption data. According to the query business type, the index value of each energy efficiency indicator is combined with the key scale of each energy efficiency indicator in the energy efficiency standard to encapsulate the query result and return it to the user end.

[0162] 6) After receiving the query results, the user end renders the data on the page, and the user can view the system energy efficiency index data, and the process ends.
