Description

Technical Field

[0001] This invention relates to the field of intelligent temperature control technology, and in particular to a method, apparatus, equipment and storage medium for controlling water supply temperature. Background Technology

[0002] With urbanization, commercial and residential buildings have been equipped with heating and cooling systems to provide a more comfortable indoor environment. Heating systems control indoor temperatures within a certain range, preventing excessively low or high indoor temperatures caused by changes in outdoor temperatures. However, during operation, the building's heat load fluctuates due to changes in various outdoor weather conditions. Therefore, to match the heating supply with the building's heat load and achieve energy savings, it is necessary to adjust the heating system promptly based on the heat load. This ensures comfortable indoor temperatures while achieving energy-saving goals.

[0003] Currently, heating systems are equipped with target temperature compensation functions to adjust the overall heating temperature based on the set ambient temperature. However, this target temperature compensation function is relatively fixed, and the compensation range cannot be dynamically adjusted to reflect actual conditions at the terminal, resulting in low accuracy and failing to achieve energy conservation and emission reduction effects. In other words, the dynamic compensation accuracy of existing heating systems is relatively low. Summary of the Invention

Based on the detection results, it calculates the corresponding temperature change deviation and trend, calculates a compensation value using the temperature change deviation and trend, and then uses the compensation value to compensate for the initial water supply temperature, thereby achieving temperature regulation of the water supply system.

[0028] This invention provides a method, apparatus, device, and storage medium for controlling water supply temperature. The method includes: acquiring the actual water supply temperature and the actual terminal temperature of a target area; performing steady-state detection on each actual water supply temperature according to a preset initial water supply temperature and a time-series relationship to obtain a steady-state detection result; and calculating the terminal reference temperature of the target area using each terminal actual temperature; if the steady-state detection result is satisfactory, calculating the temperature change trend and temperature change deviation of the target area according to the terminal reference temperature and each terminal actual temperature and a time-series relationship; compensating for terminal temperature changes in the initial water supply temperature based on the trend type of the temperature change trend and the magnitude of the temperature change deviation to obtain the target water supply temperature; and adjusting the water supply temperature according to the target water supply temperature. This invention improves the accuracy of dynamic temperature regulation during heating system operation.

[0029] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” or “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0030] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 The first embodiment of the water supply temperature control method in this invention includes:

[0031] 101. Obtain multiple actual water supply temperatures with time-series relationships in the target area, and multiple actual terminal temperatures with time-series relationships corresponding to each zone in the target area;

[0032] The embodiments of this application can acquire and process relevant data based on artificial intelligence technology. Artificial intelligence (AI) refers to the theories, methods, technologies, and application systems that use digital computers or machines controlled by digital computers to simulate, extend, and expand human intelligence, perceive the environment, acquire knowledge, and use that knowledge to obtain optimal results.

[0033] Foundational technologies for artificial intelligence generally include sensors, dedicated AI chips, cloud computing, distributed storage, big data processing, operating / interactive systems, and mechatronics. AI software technologies mainly encompass computer vision, robotics, biometrics, speech processing, natural language processing, and machine learning / deep learning.

[0034] In this embodiment, the target area refers to buildings or residential buildings with relevant water supply and heating systems installed. Furthermore, this invention is not only applicable to temperature regulation of water supply and heating systems but also to temperature regulation of central air conditioning systems. This invention uses a water supply and heating system as an example for illustration; central air conditioning systems can also use the method of this invention for equivalent replacement. The actual water supply temperature refers to the water supply temperature actually generated and delivered to the entire building by the heating system at different time stages. The actual terminal temperature refers to the ambient temperature measured by sensors placed at various points in the building. The time sequence relationship refers to the time processing relationship required for multiple temperature adjustments set according to preset time intervals. This time processing relationship includes, but is not limited to, a first time sequence relationship based on a preset corresponding time period, a second time sequence relationship satisfying a corresponding periodic time interval within the first time sequence relationship, and a third time sequence relationship divided into periods according to corresponding interval time stages within the period.

[0035] In practical applications, before obtaining relevant temperature regulation data for the water supply heating system, the entire water supply heating system must first obtain the measured ambient temperature of the building where the heating system is located before starting water supply operations, and then retrieve the water supply temperature reference table from the system, as shown in the figure below:

[0036]

[0037] This table simply provides a numerical division of ambient temperature into ranges, corresponding to different optimal water supply temperatures for each range. It uses 4°C as the dividing point and doesn't explicitly state the optimal water supply temperature; it's simply represented by NULL for clarity, as each temperature range actually has a different optimal water supply temperature. Based on the obtained ambient temperature, the corresponding ambient temperature range in the water supply temperature reference table is determined as the first temperature range. Then, the optimal water supply temperature (i.e., the reference temperature) for that range is matched and set as the initial water supply temperature for the entire heating system. This temperature is used to regulate the temperature of the entire building. Furthermore, when a change in the ambient temperature reference for the target building area is detected, the second temperature range within the current ambient temperature range in the water supply temperature reference table is determined. A new reference temperature is then matched based on this second temperature range, and the initial water supply temperature from the previous stage is reset to the new set temperature to regulate the temperature of the entire building.

[0038] In addition, the entire water supply and heating system acquires and stores historical data (historical data can be temperature data from the previous period or temperature data over a period of time) of the target area in real time or intermittently. The heating system performs real-time or intermittent operation tests on several sensors in the system. When the failure rate of the sensors deployed in each zone of the target area is detected to be greater than the preset failure rate threshold, the system matches the corresponding historical actual water supply temperature and historical ambient temperature (or matches a segment of historical temperature data with a similar temperature change curve to the historical actual water supply temperature and historical ambient temperature) in the historical record information based on the current ambient temperature and current actual water supply temperature of the target area. Then, it finds the historical target water supply temperature corresponding to the matched historical actual water supply temperature and historical ambient temperature (or a segment of historical temperature data with a similar temperature change curve to the historical actual water supply temperature and historical ambient temperature) and adjusts the water supply temperature during the fault stage of the heating system based on the found historical target water supply temperature. The system also re-matches the corresponding historical target water supply temperature at preset intervals to adjust the temperature of the heating system.

[0039] Under initial system setup and normal operation, the system acquires multiple actual water supply temperatures within the target area, corresponding to a first temporal relationship (i.e., within a specific time period), as well as multiple actual terminal temperatures within the target area, corresponding to a specific time period, for each zone within the target area. The acquisition of these temperature data, such as actual water supply temperatures and terminal temperatures, is achieved through sensors installed in the building area. These sensors can be directly connected to a heat pump for detection (wired connection), or the room temperature can be wirelessly transmitted to a centralized control system via a wireless communication channel. (The wireless method uses a 4G wireless module to transmit the values ​​detected by the temperature and humidity sensors to a cloud server, where the centralized control system then retrieves the data from the cloud. This data acquisition process involves uploading, downloading, and processing temperature and humidity data.)

[0040] 102. Based on the preset initial water supply temperature, and referring to the time sequence relationship, perform steady-state detection on each actual water supply temperature to obtain the steady-state detection results, and use the actual temperature of each terminal to calculate the terminal reference temperature of the target area;

[0041] In this embodiment, the initial water supply temperature refers to the water supply temperature set by the heating system in the current temperature regulation cycle corresponding to the second time sequence relationship; the terminal reference temperature refers to the temperature value representing the current terminal of the entire building obtained by special calculation of the temperature data monitored by various sensors located at different locations in the building; the steady-state detection refers to whether the temperature fluctuation value of each actual water supply temperature within the first time sequence relationship (i.e., within a preset time period (e.g., within 30 minutes)) is within a preset threshold range. If the fluctuation value is within the preset threshold range, the state corresponding to the actual water supply temperature within the first time sequence relationship is steady state.

[0042] In practical applications, by referring to the first time-series relationship (i.e., the corresponding time period (i.e., the first time-series interval) mentioned above), the actual water supply temperature of the preset first time-series interval is selected, and the deviation between the actual water supply temperature of the preset first time-series interval and the initial water supply temperature is calculated; then it is determined whether each deviation value is within the preset steady-state threshold range, and whether the preset initial water supply temperature has changed; if each deviation value is within the preset steady-state threshold range and the preset initial water supply temperature has not changed, then the steady-state detection result of each actual water supply temperature is determined to be passed; if there is a deviation value outside the preset steady-state threshold range or the preset initial water supply temperature has changed, then the steady-state detection result of each actual water supply temperature is determined to be failed; then, by determining the relative positional relationship of each partition in the target area, for example, based on the illumination time and intensity of the target area, and based on the relative positional relationship, the temperature influence weight corresponding to each partition is configured; thus, the terminal actual temperature corresponding to each partition is weighted according to the corresponding temperature influence weight to obtain the terminal reference temperature of the target area.

[0043] 103. If the steady-state test result is passed, then calculate the temperature change trend and temperature change deviation of the target area based on the terminal reference temperature and the actual temperature of each terminal, referring to the time series relationship.

[0044] In this embodiment, the temperature change trend refers to the relative change in the actual temperature values ​​of each terminal within the corresponding second time sequence relationship (i.e., the multiple time stages divided in the corresponding periodic time in the first time sequence relationship). It is determined using a preset steady-state threshold range. If the relative change exceeds the preset steady-state threshold, it is a positive trend; if the change does not exceed the preset steady-state threshold, it is a negative trend; and if the change is within the preset steady-state threshold, it is a flat trend. The temperature change deviation refers to the temperature difference between the actual temperature of each terminal and the initial water supply temperature.

[0045] In practical applications, if the steady-state detection result is passed, the change value of the actual end temperature for each two consecutive time intervals is calculated according to the corresponding periodic time division relationship. Then, the average change value of each change value is calculated, and the temperature change trend of the target area is determined based on the average change value. Then, multiple actual end temperatures corresponding to a preset third time interval (i.e., the last time stage divided in this period) are selected from each actual end temperature, and the average end temperature of the selected multiple actual end temperatures is calculated. Then, the difference between the average end temperature and the end reference temperature is calculated to obtain the temperature change deviation value of the target area.

[0046] 104. Based on the trend type of temperature change and the magnitude of the temperature change deviation, the initial water supply temperature is compensated for the end temperature change to obtain the target water supply temperature, and the water supply is regulated according to the target water supply temperature.

[0047] In this embodiment, the terminal temperature change compensation refers to calculating the compensation value by using the trend type of the temperature change trend and the difference in temperature change deviation, and then using the calculated compensation value to perform a weighted calculation on the initial water supply temperature to achieve temperature change compensation for the heating system.

[0048] In practical applications, based on the temperature change deviation and the ambient temperature corresponding to the initial water supply temperature, a corresponding initial temperature change compensation value is matched in a preset compensation reference table. If the temperature change trend is positive and the temperature change deviation is greater than a preset first difference, the initial temperature change compensation value is subtracted from the average change value to obtain the first temperature change compensation value. If the temperature change trend is negative and the temperature change deviation is less than a preset second difference, the initial temperature change compensation value is subtracted from the average change value to obtain the second temperature change compensation value. Then, the initial temperature change compensation value, the first temperature change compensation value, or the second temperature change compensation value is added to the initial water supply temperature to obtain the target water supply temperature. Based on the calculated target water supply temperature, the water supply temperature of the heating system is adjusted for the next adjustment cycle, ensuring that the current heating system's water supply temperature adapts to changes in the building's ambient temperature, providing a better perceived temperature for people or other organisms in the building. Real-time adjustment of the corresponding water supply temperature also reduces unnecessary heat loss and improves energy efficiency.

[0049] In this embodiment of the invention, multiple actual water supply temperatures with a time-series relationship in the target area and multiple terminal actual temperatures with a time-series relationship corresponding to each partition in the target area are obtained; based on a preset initial water supply temperature, steady-state detection is performed on each actual water supply temperature with reference to the time-series relationship to obtain a steady-state detection result, and the terminal reference temperature of the target area is calculated using each terminal actual temperature; if the steady-state detection result is passed, the temperature change trend and temperature change deviation of the target area are calculated based on the terminal reference temperature and each terminal actual temperature with reference to the time-series relationship; based on the trend type of the temperature change trend and the magnitude of the difference in temperature change deviation, terminal temperature change compensation is performed on the initial water supply temperature to obtain the target water supply temperature, and the water supply temperature is adjusted according to the target water supply temperature. Compared to existing technologies, this application acquires multiple actual water supply temperatures and terminal temperatures in the target area, performs steady-state detection on each actual water supply temperature using a preset initial water supply temperature, and calculates the terminal reference temperature. Based on the detection results, it calculates the corresponding temperature change deviation and trend, calculates a compensation value using the temperature change deviation and trend, and then uses the compensation value to compensate for the initial water supply temperature, thereby achieving temperature regulation of the water supply system. This enables highly accurate dynamic temperature regulation of the heating system under different temperature conditions.

[0050] Please see Figure 2 The second embodiment of the water supply temperature control method in this invention includes:

[0051] 201. Obtain multiple actual water supply temperatures with time-series relationships in the target area, and multiple actual terminal temperatures with time-series relationships corresponding to each zone in the target area;

[0052] 202. Based on the time sequence relationship, select the actual water supply temperature of the preset first time sequence interval, and calculate the deviation between the actual water supply temperature of the preset first time sequence interval and the initial water supply temperature;

[0053] In this embodiment, the first time interval refers to multiple time intervals divided according to time sequence relationships, that is, multiple time periods divided according to preset time intervals.

[0054] In practical applications, by referring to the corresponding time period, the actual water supply temperature of the corresponding time period is selected, and the deviation value between the actual water supply temperature of the corresponding time period and the initial water supply temperature is calculated, the deviation value corresponding to each time period is obtained.

[0055] 203. Determine whether each deviation value is within the preset steady-state threshold range, and determine whether the preset initial water supply temperature has changed;

[0056] In this embodiment, based on the calculation results of the above deviation value, it is determined whether the deviation value corresponding to the time stage is within the preset steady-state threshold range (e.g., whether it is <0.5℃), and whether the preset initial water supply temperature in the heating system has changed.

[0057] 204. If each deviation value is within the preset steady-state threshold range and the preset initial water supply temperature has not changed, then the steady-state test result of each actual water supply temperature is determined to be passed.

[0058] In this embodiment, if the deviation values ​​corresponding to the time stage are within the preset steady-state threshold range and the preset initial water supply temperature has not changed, then the steady-state detection result of the actual water supply temperature corresponding to the time stage is determined to be passed.

[0059] 205. If the deviation value is outside the preset steady-state threshold range or the preset initial water supply temperature changes, the steady-state test result of each actual water supply temperature is determined to be unsuccessful.

[0060] In this embodiment, if the deviation value corresponding to a certain time period is not within the preset steady-state threshold range or the preset initial water supply temperature changes, the steady-state detection result of each actual water supply temperature is determined to be unsuccessful. For example, if the water temperature deviation exceeds 0.5℃ during the steady-state judgment period, or the ambient temperature range changes, the timing is cleared and the steady-state timing judgment is restarted until the corresponding steady-state operating range is obtained.

[0061] 206. Determine the relative positional relationship of each partition in the target area, and configure the temperature influence weight corresponding to each partition based on the relative positional relationship;

[0062] In this embodiment, the relative positional relationship of each partition in the target area refers to the location information of each sensor installed and monitored throughout the building.

[0063] In practical applications, by acquiring the pre-defined spatial layout information of each sensor within the building, the relative positional relationship of each sensor within the building's zones is determined. Based on this relative positional relationship, the calculation weights for the actual terminal temperatures measured by the corresponding sensors in each zone are then configured. Since the installation location of each sensor can affect the detected temperature when multiple terminal temperature sensors are connected to the heating system (for example, the temperature detected on the sunny side is higher than that on the shady side due to the influence of light intensity and duration), it is necessary to configure the weight of each temperature sensor to make the final calculated terminal reference temperature more meaningful for reference and calculation.

[0064] 207. The actual terminal temperatures of each zone are weighted according to their respective temperature influence weights to obtain the terminal reference temperature of the target area.

[0065] In this embodiment, based on the weights configured above, the actual end temperatures measured by each zone sensor are weighted according to the corresponding temperature influence weights. That is, the weights are first used to calculate the temperature values ​​corresponding to the actual end temperatures, and then the temperature values ​​are added together to obtain the end reference temperature of the target area.

[0066] 208. If the steady-state test result is passed, then calculate the temperature change trend and temperature change deviation of the target area based on the terminal reference temperature and the actual temperature of each terminal, referring to the time series relationship.

[0067] 209. Based on the trend type of temperature change and the magnitude of the temperature change deviation, the initial water supply temperature is compensated for the end temperature change to obtain the target water supply temperature, and the water supply is regulated according to the target water supply temperature.

[0068] In this embodiment of the invention, multiple actual water supply temperatures with a time-series relationship in the target area and multiple terminal actual temperatures with a time-series relationship corresponding to each partition in the target area are acquired. Based on a preset initial water supply temperature, steady-state detection is performed on each actual water supply temperature according to the time-series relationship to obtain steady-state detection results. Finally, the terminal reference temperature of the target area is calculated using each terminal actual temperature. Compared to existing technologies, this application, by performing steady-state judgment on the acquired terminal actual temperatures according to the corresponding time-series relationship and calculating the corresponding terminal reference temperature based on the judged terminal actual temperatures, facilitates the initial selection of temperatures within the corresponding variation range and the real-time acquisition of the corresponding reference temperature data at the terminal, providing a time-series data basis for subsequent compensation temperature calculations.

[0069] Please see Figure 3 The third embodiment of the water supply temperature control method in this invention includes:

[0070] 301. Obtain multiple actual water supply temperatures with time-series relationships in the target area, and multiple actual terminal temperatures with time-series relationships corresponding to each zone in the target area;

[0071] 302. Based on the preset initial water supply temperature, and referring to the time sequence relationship, perform steady-state detection on each actual water supply temperature to obtain the steady-state detection results, and use the actual temperature of each terminal to calculate the terminal reference temperature of the target area;

[0072] 303. If the steady-state test result is passed, then refer to the time sequence relationship and calculate the change in actual temperature at the end of each two consecutive time sequences.

[0073] In this embodiment, if the steady-state detection result is passed, the change value between the actual end temperature of each two consecutive time stages in the current cycle is calculated by referring to the time sequence relationship (i.e., the adjacent time stages divided in the current cycle).

[0074] 304. Calculate the average change of each value, and determine the temperature change trend of the target area based on the average change.

[0075] In this embodiment, by calculating each change value, the average change of the end temperature within the entire cycle is calculated (here represented by TR (trend)). Based on the average change value, the temperature change trend of the target area is determined. For example, TR (trend) > 0.5 is regarded as a positive trend, TR (trend) < -0.5 is regarded as a negative trend, and -0.5 < TR (trend) < 0.5 is regarded as a flat trend.

[0076] 305. Select multiple actual temperatures of the terminals from the actual temperatures of each terminal, and calculate the average terminal temperature of the selected multiple actual temperatures of the terminals.

[0077] In this embodiment, the first time interval refers to a selected time period within the period, and the last period of the period is used as an example for explanation.

[0078] In practical applications, multiple terminal actual temperatures are selected from each terminal actual temperature, within a preset first time interval (i.e., the last period of the cycle), and then the average terminal temperature corresponding to the selected multiple terminal actual temperatures is calculated.

[0079] 306. Calculate the difference between the terminal average temperature and the terminal reference temperature to obtain the temperature change deviation of the target area;

[0080] In this embodiment, the temperature change deviation of the target area is obtained by calculating the difference between the above-mentioned average end temperature and the end reference temperature, where the temperature change deviation is represented by TR (average deviation).

[0081] 307. Based on the temperature change deviation and the ambient temperature corresponding to the initial water supply temperature, match the corresponding initial temperature change compensation value in the preset compensation reference table.

[0082] In this embodiment, the compensation reference table refers to a table that establishes corresponding compensation value references based on the relevant ambient temperature and the corresponding temperature change deviation value. The table of the compensation reference table is shown below:

[0083]

[0084] In practical applications, based on the temperature change deviation calculated above and the ambient temperature corresponding to the initial water supply temperature (i.e., the terminal reference temperature calculated above), the corresponding compensation value is matched in the preset compensation reference table and used as the initial temperature change compensation value.

[0085] 308. If the temperature change trend is positive and the temperature change deviation is greater than the preset first difference, then the initial temperature change compensation value is subtracted from the average change value to obtain the first temperature change compensation value.

[0086] In this embodiment, if the trend type of temperature change is positive and the temperature change deviation is greater than a preset first difference, such as temperature change deviation TR (average deviation) > 0, then the first temperature change compensation value is obtained by subtracting the average change value from the initial temperature change compensation value.

[0087] 309. If the temperature change trend is negative and the temperature change deviation is less than the preset second difference, then the initial temperature change compensation value is subtracted from the average change value to obtain the second temperature change compensation value.

[0088] In this embodiment, if the temperature change trend is a negative trend and the temperature change deviation is less than a preset second difference, such as temperature change deviation TR (average deviation) > 0, then the second temperature change compensation value is obtained by subtracting the average change value from the initial temperature change compensation value.

[0089] 310. Add the initial temperature change compensation value, the first temperature change compensation value, or the second temperature change compensation value to the initial water supply temperature to obtain the target water supply temperature.

[0090] In this embodiment, based on the above-mentioned compensation value calculation results, as well as the corresponding temperature change trend type and temperature change deviation value, one of the three compensation values ​​is selected from the initial temperature change compensation value, the first temperature change compensation value, or the second temperature change compensation value and added to the initial water supply temperature to obtain the target water supply temperature.

[0091] For example, (a) when the temperature change trend is positive, based on the compensation reference table: when TR (average deviation) > 0, the initial temperature change compensation value is determined using the terminal reference temperature in the compensation reference table, and then TR (average trend) is subtracted (for example, TR (average trend) = +1.2℃, then the target temperature for the next stage = initial water supply temperature + initial compensation value -1.2℃); when TR (average deviation) < 0, the initial temperature change compensation value is determined directly using the terminal reference temperature in the compensation reference table, and then the initial water supply temperature is added for compensation. (b) when the temperature change trend is negative, based on the compensation reference table: when TR (average deviation) > 0, the initial temperature change compensation value is determined directly using the terminal reference temperature in the compensation reference table, and then the initial water supply temperature is added for compensation; when TR (average deviation) < 0, the initial temperature change compensation value is determined using the terminal reference temperature in the compensation reference table, and then TR (average trend) is subtracted (for example, TR (average trend) = -1.2℃, then the target temperature for the next stage = initial water supply temperature + compensation value in Table 2 + 1.2℃).

[0092] Furthermore, when the temperature change trend is flat, and when -0.5℃ < TR (average deviation) < 0.5℃, the current ambient temperature range and target water temperature are updated to the supply water reference temperature, and corresponding compensation is performed using the compensation reference table under other temperature change trends; if the above average deviation range is not met, then when other temperature change trends occur, corresponding compensation is performed directly according to the compensation reference table.

[0093] Furthermore, based on the aforementioned target water supply temperature, the water supply temperature is adjusted to achieve dynamic adjustment of the heating system's water supply temperature, enabling automatic adjustment of the heating system's water supply temperature. After a period of operation, a historical adjustment record of optimal operation can also be generated.

[0094] In this embodiment of the invention, if the steady-state detection result is passed, the temperature change trend and temperature change deviation of the target area are calculated based on the terminal reference temperature and the actual temperature of each terminal, with reference to the time sequence relationship. Based on the trend type of the temperature change trend and the magnitude of the difference in the temperature change deviation, the initial water supply temperature is compensated for terminal temperature changes to obtain the target water supply temperature. The water supply is then regulated according to the target water supply temperature. Compared to existing technologies, this application calculates the temperature change trend and temperature change deviation of the target area, and then uses the trend type of the temperature change trend and the magnitude of the difference in the temperature change deviation to calculate the corresponding water temperature compensation value. This enables the calculation of dynamic compensation values ​​under different conditions of the heating system's water supply temperature and achieves highly accurate dynamic temperature regulation of the heating system under different temperature conditions.
