[0002] As people's living standards improve, the demand for intelligent water heaters is also increasing. To provide better service to users, researchers are constantly innovating to make water heaters more intelligent. For example, they can set appropriate temperature settings based on the user's water demand, heating cold water to the set temperature. This ensures that the user's water needs are met while avoiding excessive heating and energy waste. Therefore, it is necessary to obtain the user's water consumption data.

[0003] In existing technologies, a flow sensor installed at the inlet of the water heater is generally used to obtain the user's water consumption.

[0040] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0042] To clearly understand the technical solution of this application, the solutions of the prior art will be described in detail first.

[0043] In the existing technology, the method for obtaining the water consumption of a water heater is as follows: first, a flow sensor installed at the inlet of the water heater is used to collect the water flow during the water use process, and then the collected water flow is multiplied by the water use duration to obtain the water consumption during the water use process.

[0044] However, for water heaters without flow sensors, the user's water consumption cannot be obtained in this way.

[0045] To address the aforementioned technical problems, in this embodiment, the water consumption for each water usage period can be calculated by obtaining the minimum inlet water temperature and total energy consumption during that period. Then, based on the water consumption for each water usage period, the water consumption for a corresponding preset time period can be calculated. Since this application can use the minimum inlet water temperature and total energy consumption as parameters to calculate the user's water consumption, the solution provided in this embodiment can also obtain the user's water consumption for water heaters without a flow sensor.

[0046] The embodiments of this application are described in detail below with reference to the accompanying drawings:

[0047] First, the application scenarios of the embodiments of this application will be introduced:

[0048] Figure 1 This is a schematic diagram illustrating an application scenario of the water consumption acquisition method for a water heater provided in this application embodiment. This method can be executed by a water consumption acquisition device for the water heater. In practical scenarios, this water consumption acquisition device can be set up independently or it can be set up on a cloud service platform.

[0049] For water heaters without flow sensors, to obtain water usage data, the water heater uploads reported data, including but not limited to inlet water temperature, cumulative time, and cumulative energy consumption, to a water usage acquisition device in a cloud service platform. The water usage acquisition device determines relevant parameters for calculating water usage based on the reported data and then performs the calculation. The calculated water usage can be queried by the user or used in other scenarios, such as big data analysis. Figure 1As shown in the diagram, the system includes a cloud service platform 1, a water heater 2, and a user-held terminal device 3. Communication connections can be established between the cloud service platform 1 and the water heater 2, as well as between the cloud service platform 1 and the terminal device 3. For example, the cloud service platform 1 obtains and stores the water consumption data of the water heater 2 for different time periods. When a user needs to query water consumption data, they can send a query command to the cloud service platform 1 through the terminal device 3. Upon receiving the query command, the cloud service platform 1 sends the water consumption data for the corresponding time period to the terminal device 3, thus enabling the water heater water consumption query function. Alternatively, the cloud service platform 1 can also perform data analysis on the large amount of stored water consumption data to understand the user's water consumption habits.

[0050] Example 1

[0051] Figure 2 The flowchart of the water consumption acquisition method for a water heater provided in Embodiment 1 of this application is as follows: Figure 2 As shown, the execution subject in this embodiment is a water heater water consumption acquisition device. The water heater water consumption acquisition method provided in this embodiment includes:

[0052] Step 101: Determine the water usage period corresponding to each water usage event within the preset time period.

[0053] For example, in a practical application, a water heater periodically sends reported data to a cloud service platform to store the data. The water consumption monitoring device can retrieve this data from the cloud platform and determine whether a user is using water based on the water consumption flag field. For instance, a "0" in the flag field indicates no water usage, while a "1" indicates usage. The device then determines the water consumption period corresponding to each water consumption event within a preset time frame. The process of changing the flag field from "0" to "1" and then back to "0" is recorded as one water consumption event.

[0054] The preset time period can be from 19:00 to 21:00 during the day, or it can be any other time period; this embodiment does not limit this. The period for sending and reporting data at regular intervals can be a few seconds or tens of seconds; this embodiment does not limit this. In practice, multiple water usage events may occur within a single time period. For example, if the water usage flag field changes from "0" to "1" at 19:10 and then changes from "1" to "0" at 19:15, then 19:10 to 19:15 is considered the water usage period corresponding to one water usage event. Similarly, if another water usage event is detected between 19:40 and 20:40, then within the preset time period of 19:00 to 21:00, a total of two water usage events occurred, corresponding to water usage periods of 19:10 to 19:15 and 19:40 to 20:40, respectively.

[0055] Step 102: For each water usage period within the preset time period, obtain the inlet water temperature and total energy consumption of the water heater during that water usage period.

[0056] For a practical example, after determining the water usage period corresponding to each water usage event within a preset time period, the inlet water temperature and total energy consumption for each water usage period within the preset time period are obtained. The inlet water temperature can have multiple values. The total energy consumption refers to the total energy consumption of the water heater during the entire period from the beginning to the end of a single water usage period.

[0057] Taking the reported data as an example, the total energy consumption for a given water usage period can be determined based on the cumulative energy consumption data in the first and last reported data. In one implementation, if the cumulative energy consumption data at the start of the water usage period is zero, the cumulative energy consumption data at the end of the water usage period is determined as the total energy consumption for that period. In another implementation, if the cumulative energy consumption data at the start of the water usage period is not zero, the difference between the cumulative energy consumption data at the end of the water usage period and the cumulative energy consumption data at the start of the water usage period is calculated, and the result of this difference is determined as the total energy consumption for that period.

[0058] Step 103: Determine the minimum inlet water temperature during the water usage period based on the inlet water temperature of the water heater during the water usage period.

[0059] Taking a practical application example, after obtaining the inlet water temperature and total energy consumption for each water usage period within a preset time period, the water consumption acquisition device of the water heater can compare multiple inlet water temperatures obtained for the same water usage period to obtain the minimum inlet water temperature within that water usage period, and then obtain the minimum inlet water temperature for all water usage periods within the preset time period through comparison.

[0060] It should be noted that before water enters the system, there may be a certain amount of water in the inlet pipe. The water in the pipe may be higher than the tap water supply temperature due to the influence of indoor temperature. Therefore, the minimum inlet water temperature during a certain water usage period is used to represent the actual inlet water temperature.

[0061] Step 104: Calculate the water consumption during each water consumption period based on the minimum inlet water temperature and total energy consumption.

[0062] To illustrate with a practical example, based on the minimum inlet water temperature and total energy consumption, the water consumption during each corresponding water usage period within a preset time frame can be calculated. Continuing with the previous example, to calculate the water consumption of the water heater during the period from 19:00 to 21:00, specifically for the two water usage periods of 19:10 to 19:15 and 19:40 to 20:40, the water consumption of the water heater during these two periods is obtained using the methods in steps 102 to 104, so that the total water consumption for the entire period can be calculated subsequently.

[0063] Step 105: Calculate the water consumption within the preset time period based on all water consumption periods within the preset time period.

[0064] To illustrate with a practical example, after obtaining the water consumption for each corresponding water usage period within the preset time period in step 104, the water consumption for all water usage periods within the preset time period is summed to obtain the total water consumption for the preset time period. Continuing with the previous example, the water consumption of the water heater from 19:00 to 21:00 can be obtained by calculating the sum of the water consumption for the two water usage periods: 19:10 to 19:15 and 19:40 to 20:40.

[0065] In this embodiment, the water usage period corresponding to each water usage event within a preset time period is determined; for each water usage period within the preset time period, the inlet water temperature and total energy consumption of the water heater within that water usage period are obtained; based on the inlet water temperature of the water heater within that water usage period, the minimum inlet water temperature within that water usage period is determined; based on the minimum inlet water temperature and total energy consumption within each water usage period, the water consumption within that water usage period is calculated; and based on all water usage periods within the preset time period, the water consumption within the preset time period is calculated. Since this application can use the minimum inlet water temperature and total energy consumption as parameters to calculate the user's water consumption, the solution provided in this embodiment can also obtain the user's water consumption for water heaters without a flow sensor.

[0066] Example 2

[0067] Figure 3 The flowchart of the water consumption acquisition method for a water heater provided in Embodiment 2 of this application is as follows: Figure 3 As shown, based on Embodiment 1, the method for obtaining water consumption of a water heater further includes the following steps:

[0068] Step 201: Obtain multiple reported data messages sent by the water heater during each water usage period. The reported data includes the inlet water temperature field.

[0069] Accordingly, step 102, which involves obtaining the inlet water temperature of the water heater for each water usage period within a preset time period, specifically includes:

[0070] Step 202: If the inlet water temperature field is not empty or zero, extract the temperature value from the inlet water temperature field of multiple reported data and use it as the inlet water temperature of the water heater during the water usage period.

[0071] Specifically, for a specific water usage period, the water consumption acquisition device can obtain the water heater's reported data from the cloud service platform. If it is determined that the inlet water temperature field in the reported data is not empty or zero, the temperature value in the inlet water temperature field is extracted and used as the inlet water temperature of the water heater during that water usage period.

[0072] In one embodiment, after step 201, the method further includes: if the inlet water temperature field is empty or zero, obtaining the geographical location information of the water heater, and obtaining the first inlet water temperature corresponding to the preset time period and the geographical location information of the water heater from the remote server; and determining the inlet water temperature of the water heater during the water usage period based on the first inlet water temperature.

[0073] To illustrate this implementation method using a specific water usage period as an example, the water consumption acquisition device can obtain reported data from the water heater via a cloud service platform. If the inlet water temperature field in the reported data is empty or zero, the device obtains the water heater's geographical location information and retrieves the first inlet water temperature for the corresponding preset time period from a remote server based on this geographical location information. In practical applications, the inlet water temperature on the remote server can be obtained by relevant departments through surveys and statistics. For example, the statistical data may include inlet water temperature data for various regions in different months. In this case, the water consumption acquisition device can obtain the inlet water temperature data for the month in which the water heater's geographical location falls within the preset time period, and use this as the first inlet water temperature. Alternatively, the statistical data may not be differentiated by geographical location; for example, it may only include the average inlet water temperature for each region in each month. In this case, it is impossible to obtain the first inlet water temperature based on geographical location. Therefore, the average inlet water temperature for the month in the preset time period can be obtained as the first inlet water temperature.

[0074] In this embodiment, when the inlet water temperature field in the reported data is empty or zero, the inlet water temperature of the water heater during the water usage period can be obtained from the remote server to ensure the accuracy of the water consumption calculation results during the water usage period, thereby further ensuring the accuracy of the water consumption calculation results within the preset time period in which the water usage period is located.

[0075] In one embodiment, after determining the minimum inlet water temperature during the water usage period based on the inlet water temperature of the water heater during the water usage period, the method further includes: if the minimum inlet water temperature during the water usage period is not less than a preset temperature threshold, then obtaining the geographical location information of the water heater, and obtaining a second inlet water temperature corresponding to the preset time period and the geographical location information of the water heater from a remote server; and determining the inlet water temperature of the water heater during the water usage period based on the second inlet water temperature.

[0076] The preset temperature threshold can be 30℃. Taking a specific water usage period as an example, after determining the minimum inlet water temperature during that period, the minimum value is compared with the preset temperature threshold. If the minimum value is not less than the preset temperature threshold, the geographical location information of the water heater is obtained, and based on this geographical location information, the second inlet water temperature for the corresponding preset period is retrieved from a remote server.

[0077] Taking a specific water usage period as an example, if the remote server does not have second inlet water temperature data corresponding to the geographical location of the water heater, the inlet water temperature for that water usage period is obtained from a preset temperature data table. This preset temperature data table contains the average inlet water temperature for each month across various regions, obtained through surveys and statistics from relevant departments. In this embodiment, when the remote server does not have second inlet water temperature data corresponding to the geographical location, the inlet water temperature can be obtained from the preset temperature data table to ensure the accuracy of the water consumption calculation results for that water usage period, thereby further ensuring the accuracy of the water consumption calculation results for the preset time period in which that water usage period falls.

[0078] In this embodiment, when the inlet water temperature data in the reported data is abnormal, the inlet water temperature of the water heater during the water usage period can be obtained from the remote server to ensure the accuracy of the water consumption calculation results during the water usage period, thereby further ensuring the accuracy of the water consumption calculation results within the preset time period in which the water usage period is located.

[0079] In this embodiment, when the water consumption during a certain water usage period is obtained, the inlet water temperature data in the reported data is obtained, and the inlet water temperature data is substituted into the first formula to calculate the water consumption during the certain water usage period. When the inlet water temperature value is empty or zero, or when the inlet water temperature data is abnormal, the inlet water temperature is obtained from a remote server or a preset temperature data table. This can ensure the accuracy of the water consumption calculation result during the water usage period, and further ensure the accuracy of the water consumption calculation result within the preset time period in which the water usage period is located.

[0080] Example 3

[0081] This application provides a method for obtaining water consumption of a water heater in embodiment three. Based on embodiment one or two, before step 102, the method further includes:

[0082] Obtain multiple reported data messages sent by the water heater during each water usage period, wherein the reported data includes a cumulative energy consumption field;

[0083] If the cumulative energy consumption field in the last reported data is not zero, the total energy consumption of the water heater during the water usage period is determined based on the energy consumption value in the cumulative energy consumption field and the energy consumption value in the cumulative energy consumption field in the first reported data.

[0084] If the cumulative energy consumption field in the last reported data is zero, then the total energy consumption of the water heater during the water usage period is determined based on the largest energy consumption value among the cumulative energy consumption fields of the multiple reported data and the energy consumption value in the cumulative energy consumption field of the first reported data.

[0085] In this embodiment, the water consumption acquisition device acquires multiple reported data from the water heater during each water usage period. Taking a specific water usage period as an example, if the cumulative energy consumption field in the last reported data is not zero, the total energy consumption of the water heater during that water usage period is determined based on the energy consumption value in the cumulative energy consumption field and the energy consumption value in the cumulative energy consumption field of the first reported data. If the cumulative energy consumption field in the last reported data is zero, it may be due to a power outage, and the energy consumption data in the cumulative energy consumption field is set to zero after power is restored. In this case, the total energy consumption of the water heater during that water usage period can be determined based on the energy consumption value in the cumulative energy consumption field of the second-to-last reported data and the energy consumption value in the cumulative energy consumption field of the first reported data. Specifically, the difference between these two values ​​is taken as the total energy consumption of the water heater during that water usage period.

[0086] To illustrate with data, Table 1 shows a schematic of data reporting interruptions caused by a power outage. Each column in Table 1 represents a reported data entry, including but not limited to a flag, cumulative energy consumption, cumulative time, and time. The flag in Table 1 changes from "0" to "1" and then back to "0," indicating a complete water usage event. As shown in Table 1, the cumulative energy consumption data in the last column is zero. Therefore, the difference between the cumulative energy consumption data (120) in the second-to-last column and the cumulative energy consumption data (0) in the second column is calculated to obtain 120, which is then determined as the total energy consumption of the water heater during that water usage period. Using the solution provided in this embodiment, even if a power outage occurs during a certain water usage period, a relatively accurate total energy consumption value for that period can be obtained, thus ensuring the accuracy of the water usage data obtained within that preset period.

[0089] This application provides another method for obtaining water consumption of a water heater in Embodiment 3. Based on Embodiment 1 or Embodiment 2, before step 102, the method further includes:

[0090] Acquire multiple reported data messages sent by the water heater at different times during each water usage period. The reported data includes the cumulative time field and the cumulative energy consumption field corresponding to different sending times.

[0091] If the cumulative time field value in the later reported data is less than the cumulative time field value in the earlier reported data, then the water usage period corresponding to the time of the earlier reported data and the time before and after the time of the later reported data will be split into different water usage periods to update the water usage periods within the preset time period.

[0092] The reported data corresponds to the time when the water heater sends the reported data. In this embodiment, the water consumption acquisition device acquires multiple reported data messages sent by the water heater during each water consumption period. Taking a specific water consumption period as an example, the device acquires the corresponding time field, cumulative time field, and cumulative energy consumption field from all reported data for that water consumption period. If, in two adjacent reported data messages, the value of the cumulative time field in the later reported data message is less than the value of the cumulative time field in the earlier reported data message, it is determined that the cumulative time has restarted counting during the time period between the reporting times of these two data messages, which means the cumulative energy consumption has restarted counting. Therefore, the water consumption period corresponding to the time of the earlier reported data message and the time before and after the time of the later reported data message is divided into different water consumption periods to update the water consumption periods within the preset time period.

[0093] To illustrate with the data, Table 2 shows a schematic diagram of the restart of cumulative energy consumption counting. Each column in Table 2 represents a reported data point, including but not limited to a flag, cumulative time, and time. The flag in Table 2 changes from "0" to "1" and then back to "0," indicating a complete water usage event. As shown in Table 2, the cumulative time data in column 6 is less than the cumulative time data in column 5. This confirms that the cumulative time count restarted within the time interval between these two reported data points, meaning the cumulative energy consumption count restarted. Therefore, the water usage period before 10:30 in column 5 and after 11:30 in column 6 are split into two different water usage periods, defined as Event 1 and Event 2, to update the water usage period within the preset time frame. Using the solution provided in this implementation, even when the cumulative time count restarts, the calculation of water consumption is not omitted, thus ensuring the accuracy of the obtained water consumption data within the preset time frame.

[0094] Table 2

[0095]

[0096] This application provides a third embodiment of a method for obtaining water consumption from a water heater, which, based on embodiment one or two, further includes the following method before step 102:

[0097] Obtain multiple reported data messages sent by the water heater at different times during each water usage period. The reported data includes the sending time of the reported data and the cumulative time field corresponding to the different sending times.

[0098] If the time interval between the start times of water use corresponding to adjacent reported data is greater than a preset time threshold, the water use period corresponding to the time of the previous reported data and the time before and after the time of the next reported data will be divided into different water use periods to update the water use periods within the preset time period.

[0099] The start time of water use corresponding to the reported data is the time corresponding to the reported data minus the value in the cumulative time field of the reported data.

[0100] In this embodiment, the water consumption acquisition device acquires multiple reported data messages sent by the water heater during each water consumption period. The time corresponding to the reported data refers to the time when the water heater reported the data, and the reported data includes the time of the reported data. Taking a specific water consumption period as an example, the device acquires the cumulative time field from all reported data for that period. If, in two adjacent reported data messages, the difference between the time and the cumulative time (the value in the cumulative time field) in the later reported data message and the difference between the time and the cumulative time in the earlier reported data message are greater than a preset time threshold, meaning the time interval between the start times of the two adjacent reported data messages is greater than the preset time threshold, then a data reporting interruption is determined. The water consumption period corresponding to the time before and after the earlier reported data message and the time corresponding to the time after the later reported data message are then divided into different water consumption periods to update the water consumption periods within the preset time period. The preset time threshold can be set based on statistical data or experience; for example, it can be 30 minutes.

[0101] To illustrate this, Table 3 shows a diagram illustrating data reporting interruptions caused by network outages. Each column in Table 3 represents a reported data entry, including but not limited to a flag, cumulative time, and time. The flag in Table 3 changes from "0" to "1" and then back to "0," indicating a complete water usage event. As shown in Table 3, the difference between the time data and cumulative time data in column 6 and the difference between the time data and cumulative time data in column 5 exceeds 30 minutes. Therefore, the water usage periods at 10:30 and before in column 5 and at 13:30 and after in column 6 are split into two distinct water usage periods, defined as Event 1 and Event 2, to update the water usage periods within the preset time frame. Using the solution provided in this embodiment, when a data interruption occurs, splitting the water usage periods and then calculating the water consumption yields more accurate water consumption data within the preset time frame.

[0102] Table 3

[0103]

[0104] It should be noted that the above implementation methods can be implemented individually or in combination, depending on the actual reported data. For example, if multiple scenarios occur during a certain water usage period, the corresponding implementation methods can be combined for calculation. Furthermore, the implementation method for obtaining total energy consumption under different scenarios provided in this embodiment and the implementation method for obtaining inlet water temperature under different scenarios in Embodiment 2 can also be implemented in combination. When implemented in combination, both may involve reporting data. Therefore, the steps for obtaining the reported data can be merged, meaning the reported data includes the required data, such as the inlet water temperature field, cumulative time field, and cumulative energy consumption field, without needing to obtain the reported data separately.

[0105] In this embodiment, updating the water usage periods within a preset time period refers to re-dividing each water usage period within the preset time period. Accordingly, when calculating the water consumption within the preset time period, steps 102 to 104 are first executed for each updated water usage period to obtain the water consumption for each updated water usage period. Then, the water consumption of all updated water usage periods is summed to obtain the water consumption for the preset time period.

[0106] In this embodiment, when obtaining the total energy consumption during a certain water usage period, various abnormal situations are considered, such as power outages caused by human intervention, the restart of cumulative energy consumption counting, and network interruptions. A method for obtaining the total energy consumption is provided for each abnormal situation, which can ensure the accuracy of the water consumption calculation results during that water usage period, thereby further ensuring the accuracy of the water consumption calculation results within the preset time period in which that water usage period is located.

[0107] Example 4

[0108] Based on any of the above embodiments, the water consumption during each water consumption period is calculated according to the minimum inlet water temperature and total energy consumption, including:

[0109] Based on the minimum inlet water temperature and total energy consumption during each water usage period, and using the first formula, the water consumption during that period is calculated. The first formula is:

[0110] V = 100 * E t / [C*(T 出 -T 进 )],

[0111] Where V represents the water consumption during the water usage period, and E t T represents the total energy consumption of the water heater during the water usage period, where C is the specific heat capacity of water, and T is the total energy consumption of the water heater during the water usage period. 出 T is the preset outlet water temperature. 进 This is the minimum inlet water temperature of the water heater during the water usage period.

[0112] Among them, T 出 The temperature is generally 40℃.

[0113] In this embodiment, when calculating the water consumption for a certain water usage period, the minimum inlet water temperature and total energy consumption within that water usage period are substituted into the first formula to calculate the water consumption for that water usage period. In this embodiment, by utilizing the physical relationship between inlet and outlet water temperatures, total energy consumption, and water consumption, a relatively accurate water consumption for that water usage period can be obtained.
