Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning control, and in particular to a control method and system for measuring the performance of air conditioning users under working conditions based on big data. Background Art

[0002] Single air conditioners are installed in thousands of households. In summer, the operation of air conditioners is affected by many factors, including the outdoor temperature of the day, the room orientation, the window layout, the thickness of the wall insulation layer, the wind speed set by the user, the gear set by the user, etc., so that the actual operation conditions vary greatly, and the final temperature that the indoor temperature can drop to is also different. From a professional perspective, the cooling capacity required by the air conditioner can be calculated by statistically analyzing the various influencing factors in the environment where the single air conditioner is located, and then using a formula to calculate the cooling capacity of the air conditioner, so as to confirm whether the air conditioner can reach the set temperature, but it is usually impossible to obtain accurate influencing factor data, and thus it is impossible to calculate the accurate cooling capacity. Summary of the invention

[0003] The purpose of the present invention is to provide a control method and system for measuring the performance of air conditioners under user working conditions based on big data, so as to solve the technical problem that the prior art cannot fully obtain all the influencing factor data of a single air conditioner, resulting in the inability to accurately calculate the cooling capacity of the air conditioner and the inability to confirm whether the set temperature can be reached.

[0004] The present invention solves the above problems through the following technical solutions:

[0005] The control method based on big data to measure the capacity of air conditioner users under working conditions includes:

[0006] Step S1: Establishing an air conditioning capacity database:

[0007] When the air conditioner is turned on, the historical operation data of the air conditioner is judged one by one. If the indoor temperature in the key field of the air conditioner is the same for n consecutive times, and n≥3, the key field content described in the data is recorded, so as to complete the judgment of each data at each startup, and all the key field contents at the corresponding time that meet the conditions are recorded and stored in the database to form the air conditioner capacity database;

[0008] Step S2: Screening and filtering of air conditioning capacity database:

[0009] Perform secondary processing on the data in the air conditioning capacity database, retaining only the lowest or highest data with different indoor temperatures in the key fields of the air conditioning as the final indoor temperature value that the single air conditioning can reach under the set conditions;

[0010] Step S3: Verify the air conditioning capacity database:

[0011] Verify the filtered air conditioning capacity database to remove interference data that cannot reflect the air conditioning refrigeration capacity;

[0012] Step S4: query the air conditioning capacity database:

[0013] Automatically match the key field content of the air conditioner and output the corresponding final indoor temperature value that the air conditioner can reach under the set conditions in the air conditioner capacity database;

[0014] Step S5: operate the air conditioner according to the final indoor temperature value obtained.

[0015] As a further improvement, in step S1, each data in the air conditioner startup data is arranged in ascending order by timestamp.

[0016] As a further improvement, the key fields include: outdoor temperature, user-set wind speed level, user-set mode, current time, user-set temperature, air conditioning equipment number and indoor temperature.

[0017] As a further improvement, in step S3, the verification content of the air conditioning capacity database includes the outdoor temperature and the wind speed level set by the user.

[0018] As a further improvement, in step S4, the automatically matched air-conditioning key field content at least includes the air-conditioning equipment number, outdoor temperature, current time, user-set wind speed level and user-set temperature.

[0019] As a further improvement, in step S4, the user-set wind speed level and the user-set temperature are input through an air-conditioning remote controller.

[0020] As a further improvement, the final indoor temperature value is displayed on an air-conditioning remote controller or an air-conditioning panel so that the user can modify the content of the key field of the air-conditioning.

[0021] As a further improvement, in step S5, the air conditioner is operated according to the final indoor temperature value obtained, and the specific method is as follows:

[0022] When the air conditioner cannot reach the user-set temperature, that is, in cooling mode, the user-set temperature value is less than the final indoor temperature value, the air conditioner will operate according to the final indoor temperature value; in heating mode, the user-set temperature value is greater than the final indoor temperature value, the air conditioner will operate according to the final indoor temperature value;

[0023] When the air conditioner can reach the user-set temperature, that is, in cooling mode, the user-set temperature value ≥ the final indoor temperature value, the air conditioner will operate according to the user-set temperature; in heating mode, the user-set temperature value ≤ the final indoor temperature value, the air conditioner will operate according to the user-set temperature.

[0024] At the same time, the present invention also solves the above problems through the following technical solutions:

[0025] A control system for measuring the capacity of air conditioners under user working conditions based on big data, comprising: an air conditioner data processor, a big data platform and an air conditioner remote controller, wherein the air conditioner data processor communicates with the big data platform and the air conditioner remote controller, and obtains the previous historical operation data of the air conditioner stored in the big data platform through the air conditioner data processor to establish an air conditioner capacity database; and the established air conditioner capacity database is screened, filtered, verified and queried to obtain a final indoor temperature value, and the key field content of the air conditioner operation is adjusted according to the obtained final indoor temperature value, so that the air conditioner realizes the control method for measuring the capacity of air conditioners under user working conditions based on big data as described above.

[0026] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0027] The present invention is based on the air-conditioning status data reported to the cloud by a single air-conditioner, and sorts out and extracts the data content of key fields in each startup cycle of the air-conditioner, including outdoor temperature, user-set wind speed level, user-set mode, current time, and user-set temperature, and obtains them by classification processing, so as to obtain the lowest temperature value or the highest temperature value that can be reached in the room under different outdoor temperatures, wind speed levels, time periods, and indoor set temperatures, which is regarded as the cooling or heating capacity of the air-conditioner in the user's home under various working conditions, and is stored in a database in the form of multi-dimensional data. By inputting the data of the current environment into the database at subsequent startup, the temperature value that the air-conditioner can finally reach can be obtained, which is used for the air-conditioner to formulate a better cooling strategy and improve the working efficiency of the air-conditioner.

[0030] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0031] In the description of the present application, it should be noted that, unless expressly provided and limited otherwise, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or display comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or inherent to these processes, methods, products or displays.

[0032] The following will be combined Figure 1-2 , a control method and system for measuring the capacity of air conditioner users under working conditions based on big data according to an embodiment of the present application are described in detail. It is worth noting that the following embodiments are only used to explain the present application and do not constitute a limitation on the present application.

[0033] Embodiment 1:

[0034] Combined with Figure 1 As shown, the control method for measuring the capacity of air conditioner users under working conditions based on big data specifically includes the following steps:

[0035] Step S1: Establishing an air conditioning capacity database:

[0036] When the air conditioner is turned on, the historical operation data of the air conditioner is judged one by one. If the indoor temperature in the key field of the air conditioner is the same for n consecutive times, and n≥3, the key field content described at that moment is recorded, so as to complete the judgment of each data at each startup, and all the key field contents at the corresponding moments that meet the conditions are recorded and stored in the database to form an air conditioner capacity database.

[0037] In this embodiment, after a single air conditioner is installed in a household, based on the user's usage habits, after the air conditioner is turned on and off multiple times, the cloud can obtain a large amount of historical operation data of the air conditioner's operating status. The cloud stores the historical operation data of the air conditioner in a memory for retrieval the next time the air conditioner is turned on; and each data in the air conditioner startup data is arranged in ascending order by timestamp to facilitate data judgment item by item.

[0038] Optionally, key fields include: outdoor temperature, user-set wind speed level, user-set mode, current time, user-set temperature, air conditioning equipment number and indoor temperature, etc.

[0039] Step S2: Screening and filtering of air conditioning capacity database:

[0040] Perform secondary processing on the data in the air conditioning capacity database established in step S1, retaining only the data with different indoor temperatures and the lowest or highest value in the key field of the air conditioning as the final indoor temperature value that the single air conditioner can reach under the set conditions;

[0041] Specifically, in this embodiment, the data stored in the air conditioning capacity database is processed secondary to match the user-set wind speed level, user-set temperature, and outdoor temperature contained in the air conditioning capacity database with a fixed air conditioning equipment number in the cooling mode. There are usually multiple different indoor temperatures, and only the lowest indoor temperature is retained, and other indoor temperature values ​​under the same conditions are deleted. In theory, this indoor temperature value is regarded as the final indoor temperature value that can be reached by the single air conditioner under the conditions of the corresponding user-set wind speed level, the corresponding outdoor temperature, and the corresponding user-set temperature, which reflects the cooling capacity of the single air conditioner.

[0042] The following is an example of Table 1: Under the same conditions, there are three different indoor temperature values. Only the data corresponding to the indoor temperature of 18°C ​​is retained, and the other two data are deleted.

[0043]

[0046] Step S3: Verify the air conditioning capacity database:

[0047] Verify the air conditioning capacity database after screening and filtering in step S2 to remove interference data that cannot reflect the air conditioning refrigeration capacity;

[0048] Specifically, in this embodiment, the air conditioning capacity database after processing in step S2 still has problems such as insufficient data collection under certain working conditions and unstable working conditions caused by users opening doors and windows. In this case, the actual cooling capacity of the air conditioner cannot be reflected and needs to be verified and eliminated according to normal logic. The verification content includes outdoor temperature, user-set wind speed level, etc.

[0049] The following table 2 is used as an example to illustrate: The following table shows an example of checking the outdoor temperature. The outdoor temperature can reach the set temperature of 18°C ​​at 31°C and 33°C, but it cannot reach 18°C ​​at 32°C, which is obviously not in line with common sense. Therefore, the corresponding data is deleted.

[0050]

[0051] Table 2 Database verification diagram

[0052] Step S4: query the air conditioning capacity database:

[0053] Automatically match the key fields of air conditioners such as air conditioner equipment number, outdoor temperature, indoor temperature, user-set temperature, user-set wind speed level and user-set mode, and output the corresponding final indoor temperature value in the air conditioner capability database;

[0054] Specifically, in this embodiment, after the air conditioning equipment number, outdoor temperature, current time, user-set wind speed level and user-set temperature fixed value are input through the air conditioning remote control, the corresponding indoor temperature value in the air conditioning capacity database is automatically output, and can be displayed on the air conditioning remote control or on the air conditioning panel for the user to observe whether it meets the user's needs, so as to modify the content of the air conditioning key fields for the user to make adjustments.

[0055] The following is an example through Table 3: when the air conditioner number D3N8006 is input, the outdoor temperature is 31°C, the set wind speed is 1, and the indoor set temperature is 18°C, the output indoor temperature 18°C ​​represents the temperature value that the indoor temperature can reach under the environmental conditions.

[0056] Air Conditioner No. Outdoor temperature Set wind speed Indoor temperature Indoor set temperature Is it daytime? D3N8006 31℃ 1 18℃ 18℃ yes D3N8006 33℃ 1 18℃ 18℃ yes D3N8006 34℃ 1 18.3℃ 18℃ yes D3N8006 35℃ 1 18.2℃ 18℃ yes D3N8006 36℃ 1 18.1℃ 18℃ yes

[0057] Table 3. Database table data after processing

[0058] Step S5: operate the air conditioner according to the final indoor temperature value obtained in step S4.

[0059] When the air conditioner cannot reach the user-set temperature, that is, in cooling mode, the user-set temperature value is less than the final indoor temperature value, the air conditioner will operate according to the final indoor temperature value; in heating mode, the user-set temperature value is greater than the final indoor temperature value, the air conditioner will operate according to the final indoor temperature value;

[0060] When the air conditioner can reach the user-set temperature, that is, in cooling mode, the user-set temperature value ≥ the final indoor temperature value, the air conditioner will operate according to the user-set temperature; in heating mode, the user-set temperature value ≤ the final indoor temperature value, the air conditioner will operate according to the user-set temperature.

[0061] For example: when the air conditioner cannot reach the temperature set by the user, such as the set temperature in cooling mode is 16°C, the final indoor temperature value can only reach 20°C. The frequency of the air conditioner compressor will always be at the highest speed, and the energy consumption will be relatively high. If the air conditioner knows that it can only reach 20°C in the end, it will run according to the set temperature of 20°C. When it is about to reach 20°C, the frequency of the compressor will be gradually reduced, thus achieving energy saving.

[0062] When the air conditioner can reach the temperature set by the user, for example, the user sets the temperature to 20℃, the final indoor temperature can also reach 20℃. The air conditioner itself will reach 20℃ as quickly as possible before starting to reduce the compressor frequency. Because the frequency reduction timing is too late, the actual indoor temperature usually drops to lower than the set temperature, such as 19℃. When we know that the air conditioner can reach 20℃ in this environment, we can start to reduce the frequency when the indoor temperature reaches 21℃, and finally reach 20℃ smoothly, thus achieving energy saving.

[0063] The present invention utilizes air conditioner networking, and the single air conditioner will report the real-time operation status data to the big data platform. The data can be processed by the cloud layout algorithm to achieve various function optimization requirements, thereby providing a good technical environment support for product optimization. By being able to predict in advance the indoor temperature data that the air conditioner can eventually reach each time the air conditioner is turned on, the air conditioner can formulate a more reasonable cooling process, which not only ensures the rapid cooling of the room, but also achieves the maximum energy saving of the air conditioner, bringing huge practical value to users.

[0064] Embodiment 2:

[0065] Refer to Figure 2 , a control system for measuring the capacity of air conditioners under user working conditions based on big data, which is used to implement the control method for measuring the capacity of air conditioners under user working conditions based on big data as described in Example 1, including: an air conditioner data processor, a big data platform, an air conditioner remote control and a control panel, the air conditioner data processor communicates with the big data platform and the air conditioner remote control; the air conditioner data processor obtains the previous historical operation data of the air conditioner stored in the big data platform to establish an air conditioner capacity database; and the established air conditioner capacity database is screened, filtered, verified and queried to obtain a final indoor temperature value, and the key field content of the air conditioner operation is adjusted according to the obtained final indoor temperature value, so that the air conditioner can reach a preset temperature value, achieve better refrigeration efficiency control and realize efficient operation of the air conditioner.

[0066] In the specific implementation process, the indoor temperature in the air conditioning key field is the same for n consecutive times, and the relatively stable temperature of the indoor temperature is adopted, that is, there is no temperature change for 3 consecutive minutes. Of course, it can also be a time interval in which there is no temperature change at other times.

[0067] Under the same external environment, namely, outdoor temperature, user-set wind speed, user-set temperature, and whether it is daytime, only the lowest indoor temperature value is retained, and the corresponding data of other indoor temperature values ​​under this environment are deleted. Of course, since the air conditioner has two modes, cooling and heating, the temperature can also be retained at the highest indoor temperature value to control the heating capacity of the heating mode.

[0068] Although the present invention is described herein with reference to the illustrative embodiments of the present invention, the above embodiments are only preferred embodiments of the present invention, and the embodiments of the present invention are not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and embodiments, which will fall within the scope and spirit of the principles disclosed in this application.
