Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and the following embodiments are used for illustrating the present invention and are not intended to limit the scope of the present invention.
Example one
A method for predicting water consumption behaviors of a water heater comprises the steps that a data processing unit analyzes water consumption data of a user before the current time to establish a water consumption model, predicts a water consumption time period of next water consumption after the current time according to the water consumption model, counts water consumption data of N days before the current time in the water consumption time period, and predicts a specific water consumption time point of the user in the next water consumption time period.
At present, the prediction of the water consumption behavior of a user is usually calculated by using a controller of a machine, only a water consumption time period can be predicted, but a time point cannot be specified, so that the prediction error is large, and if the water consumption time period is long, a water heater is not heated when the user possibly uses hot water, and inconvenience is brought to the use of the user.
According to the invention, the water consumption model is established for the water consumption data (namely historical water consumption data) of the user before the current time through the data processing unit, the water consumption time period of the next water consumption is firstly predicted, and then the water consumption time point is further accurately predicted through the water consumption data in the water consumption time period N days before, so that the prediction is more accurate.
The method for establishing the water model (namely the water model X) comprises the following steps:
the water usage data including water temperature, flow rate and time is based on known basic model tools such as statistical models, thermodynamic models, and kinetic models, etc. and water usage data.
Obtaining a water consumption model A according to the statistical model and the water consumption data,
obtaining a water use model B according to the thermodynamic model and the water use data,
obtaining a water use model C according to the dynamic model and the water use data,
combining the actual water consumption data of the previous N days (generally the water consumption data of 3 days before the current time), fitting to obtain a water consumption model X,
X＝αA+βB+λc
the water consumption time period obtained by adopting the water consumption model X for prediction is more accurate.
Further, predicting a water use time point in a next water use period comprises:
and the data processing unit counts the specific water using time point in the water using time period every N days before the current time, and predicts the specific water using time point of the next water using according to the water using time point.
Since the water using time point of each day of the user may have a certain time error, the specific water using time point of the next water using time is predicted according to the specific water using time point in the water using time period on each day of N days before the current time.
For example, the probability of which time point the user is at can be obtained according to the specific time point, so that the specific water using time point of the next water use is predicted, the water using time period is accurate to the specific water using time point, the error is smaller, and the user experience is good.
Further, the data processing unit processes the actual water using time points of the previous N days by adopting a weighted average method, and predicts the specific water using time point of the next water using.
The specific water using time points in the water using time period are counted every N days before the current time, the weights corresponding to the water using time points are different, and the specific water using time point of the next water using is predicted by a weighted average method, so that the obtained specific water using time point is more practical and accurate by introducing weight ratio.
The weight ratio can be preset by the water heater, can be calculated according to historical data, and can be any other available weight ratio mode.
The following explanation is given by the water heater preset weight ratio:
the water heater presets a weight ratio corresponding to each of N days before the current time, the data processing unit counts water using time points in the water using time period of each of N days before the current time, and specific water using time points in the next water using time period are predicted according to the water using time points in the N days before the current time and the weight ratio corresponding to the water using time points.
The user may preset the weight ratio according to the distance between N days before the current time and the current time, and the weight ratio is larger the closer the number of days is to the current time, for example, the weight ratio of the 1 st day before the current time is the largest, the weight ratio of the 2 nd day before the current time is the second, and so on.
The weight ratio may be set according to the importance of each day of the week, with one week being a unit according to the water usage habit of the user. For example, the user may have the greatest weight on weekends of the week and a lesser weight on mondays.
Further, according to the water using time point N days before the current time and the weight ratio, the specific water using time point in the next water using time period is predicted, including,
the data processing unit calculates the difference delta t between the water using time point in the water using time period and the starting time point of the water using time period on each day of the previous N daysi(i is more than or equal to 1 and less than or equal to N, i is a positive integer), and obtaining a difference value delta t according to each day of the previous N daysiAnd the weight ratio corresponding to the time interval is used for predicting the specific water using time point in the next water using time interval.
Because the water using time point of each day in the previous N days has certain fluctuation, the calculation amount is reduced by calculating the difference value delta t, the specific water using time is calculated according to the difference value delta t and the weight ratio corresponding to the difference value delta t, and the error is smaller.
The following describes a method for predicting a specific water consumption time point of a user, including the following steps:
the data processing unit analyzes all water consumption data of the user before the current time to establish a water consumption model X, and predicts the next water consumption time period after the current time as t according to the water consumption model Xa-tb；
The data processing unit presets a weight ratio W corresponding to each of the previous N days before the current timei(i is more than or equal to 1 and less than or equal to N, and i is a positive integer);
counting the water consumption time t of the previous N days before the current timea-tbTime t of internal water consumptioni(i is more than or equal to 1 and less than or equal to N, i is a positive integer), according to the weight ratio WiWater consumption time tiAnd a starting point in time taCalculating the difference value delta t of each day of the previous N daysi＝ti-taAnd calculating the next water using time period ta-tbThe predicted value t of the specific water consumption time point in the water consumption is t ═ ta+(△t1*W1+△t2*W2……+△ti*Wi)。
Further, the method for predicting the water consumption behavior of the water heater further comprises the steps of predicting the water consumption time of the next water consumption, specifically comprising,
and the data processing unit counts the water use duration in the water use time period N days before the current time and predicts the water use duration of the next water use.
The calculation of the next time of water consumption adopts an arithmetic mean calculation mode, which specifically comprises the following steps:
the data processing unit analyzes the water consumption data of the user before the current time to establish a water consumption model X, and predicts the next water consumption time period t after the current time according to the water consumption model Xa-tb；
The data processing unit calls the current use t of N days before the current use of watera-tbActual water usage time Si(i is more than or equal to 1 and less than or equal to N, and i is a positive integer), and calculating to obtain a predicted value S of the water using time length of next water using (S ═ S)1+S2+……Si+……SN)/N。
Furthermore, the method for predicting the water consumption behavior of the water heater by the user further comprises the steps of correcting and optimizing the water consumption model X,
after the next actual water consumption, the data processing unit acquires the actual water consumption data, corrects the water consumption model X according to the actual water consumption data,
and/or after next actual water consumption, transmitting the actual water consumption data to the storage unit to update the water consumption database, and analyzing the updated water consumption database by the data processing unit to optimize the water consumption model X.
Specifically, after the next actual water consumption, the actual water consumption time point and the water consumption duration are transmitted to the storage unit to update the water consumption database, the data processing unit analyzes the updated water consumption database again, and the original water consumption model X is corrected and fitted to obtain the optimized new water consumption model.
At present, the method for calculating the water consumption behavior of the water heater for predicting the user has the defect of fixed algorithm, only parameter values in the method can be modified according to actual habits, and an algorithm model cannot be automatically modified.
As shown in fig. 1, a method for predicting water consumption behavior of a user for a water heater includes the following steps:
s1 the data processing unit analyzes all the water consumption data of the user before the current time to establish a water consumption model X, and predicts the next water consumption time period after the current time according to the water consumption model X;
s2, counting the water using time points and the water using time lengths in the water using time period N days before the current time;
s3, forecasting the specific water using time point and the water using time length of the next water using according to the water using time point and the water using time length of the previous N days obtained by statistics;
s4 after the next actual water usage, the data processing unit corrects the water usage model X using the actual water usage data.
Example two
As shown in fig. 2, the present embodiment is a specific solution to the first embodiment, and a method for predicting water consumption behavior of a user for a water heater includes the following steps:
the data processing unit analyzes all water consumption data of the user before the current time to establish a water consumption model X, wherein X is alpha A + beta B + lambda c, and the next water consumption time period after the current time is predicted to be t according to the water consumption model Xa-tb；
The data processing unit presets a weight ratio W corresponding to each of N days before the current timei(i is more than or equal to 1 and less than or equal to N, and i is a positive integer);
counting N days before the current time in the water using time period ta-tbSpecific water consumption time tiAnd the water using time length Si (i is more than or equal to 1 and less than or equal to N, i is a positive integer), and calculating the water using time point t of each day of the previous N daysiAnd taDifference Δ t ofi＝ti-taAnd further calculate the next water using time period ta-tbThe predicted value t of the specific water consumption time point in the water consumption is t ═ ta+(△t1*W1+△t2*W2……+△ti*Wi)，
Calculating the predicted value S of the water using time length of the next water using ═ S (S)1+S2+……Si+……SN)/N，
And after next actual water consumption, transmitting the actual water consumption data to the storage unit to update the water consumption database, analyzing the updated water consumption database by the data processing unit, and correcting and fitting the original water consumption model X to obtain an optimized water consumption model X'.
For example, if the current time is 7 months, 8 days, 9: 00.
A method for predicting water consumption behavior of a user for a water heater comprises the following steps:
s1 the water heater presets the weight ratio of the 7 th day before the current time, and the weight ratios from the 7 th day to the 1 st day are 5%, 8%, 10%, 12%, 15%, 20% and 30% in sequence;
s2 the data processing unit analyzes all the water consumption data of the user before the current time to establish a water consumption model X, and predicts the next water consumption time period 10:00-12:00 after the current time according to the water consumption model X;
s3, counting the water consumption data in the water consumption time period 10:00-12:00 in 7 days before the current time (7 months 1-7 months 7 days), as follows:
water usage data for 7 months and 1 day: the water consumption time is 10:01, and the water consumption time is 22 min; water usage data for 7 months and 2 days: the water consumption time is 10:20, and the water consumption time is 18 min; water usage data for 7 months and 3 days: the water consumption time is 10:16, and the water consumption time is 24 min; water usage data for 7 months and 4 days: the water consumption time is 10:35, and the water consumption time is 15 min; water usage data for 5 days 7 months: the water consumption time point is 10:27, and the water consumption time is 31 min; water usage data for 6 days 7 months: the water consumption time is 10:38, and the water consumption time is 22 min; water usage data for 7 months and 7 days: the water consumption time point is 10:40, and the water consumption time is 22 min.
S4 calculates the difference Δ t1 between 7 months and 7 days as 10:40-10:00 as 40min, the difference Δ t2 between 7 months and 6 days as 10:38-10:00 as 38min, and so on, calculates the difference Δ t7 between 10:01-10:00 as 1min, and calculates the predicted value t as 10:00 + (40 × 30% +38 × 20% + … … +1 × 5%) min ═ 10h31min, i.e. the predicted specific water usage time for the next usage of water is 10: 31;
calculating the water using time length s to be (22+18+24+15+31+22+19)/7 to be 22min, namely the predicted specific water using time length of the next water using;
s6, when the user actually uses water in 10:00-12:00 in 7/8 days, the actual water usage data is gathered into a water usage database, a data processing unit analyzes the new database, if the actual water usage data is completely the same as the predicted value, a water usage model X is unchanged, if deviation exists, the water usage models are regenerated to be A, B and C, the data of the previous 3 days are changed, the fitted alpha, beta and lambda are changed to form a new water usage model X ', and then the water usage model X' is used for carrying out subsequent water usage time period prediction. The self-correction of the water heater is realized by the correction mode, and the water heater is more intelligent.
Example three:
the water heater adopting the method for predicting the water consumption behavior of the user as described in the first embodiment and the second embodiment comprises a data processing unit and a storage unit, wherein the storage unit stores water consumption data of the user at all times, the data processing unit establishes a water consumption model X according to the water consumption data of the user at all times stored in the storage unit, and predicts the next water consumption time period according to the water consumption model X.
Furthermore, the storage unit is arranged on the cloud storage server, all water consumption data of the user are stored on the cloud server, the processing unit uses the modeling tool to establish the water consumption model X, and the next water consumption time period is predicted according to the water consumption model X.
Alternatively, the storage unit is a local storage unit provided on the household appliance.
At present, the prediction of the water consumption behavior of the user is usually calculated by using a controller of the machine, and the prediction is limited by a ROM (read only memory) of the controller, a memory and capacity, only data in a period of time (such as 21 days, 49 days and the like) can be analyzed, and the realization algorithm is also limited by the capacity. To realize the data storage and processing capacity of the invention, a cloud storage server is preferably adopted, the prediction function is realized based on cloud big data, the data volume of historical data is not limited, and the storage and operation functions are stronger.
Further, the water heater also comprises a detection unit, wherein the detection unit is used for detecting water flow, acquiring the water using time point and the water using time length of a user according to the water flow value and transmitting the water using time point and the water using time length to the storage unit.
The method comprises the steps that a detection unit detects water flow in a water heater, when the detection unit detects that the water flow value is larger than 0, water flows, the time point is the water use starting time point, timing is started, when the detection unit detects that the water flow value is smaller than or equal to 0, water is static, the time point is the water use stopping time point, timing is finished, and a data processing unit calculates the water use time length according to the water use starting time point and the water use stopping time point, namely the difference value of the water use time point and the water use stopping time point is calculated.
Example four
A data processing unit analyzes historical water consumption data of a user before the current time, predicts a specific water consumption time point and/or water consumption of next water consumption after the current time, and controls the water heater to select different function modes according to the specific water consumption time point and/or water consumption.
The water heater has multiple functional modes, the current water heater usually adopts a user to select a heating mode independently, and under the influence of user estimation errors (time estimation errors and heating temperature estimation errors), the selected water using mode is heated too fast or the heating time is too early, so that the heated hot water is too low in temperature and is not suitable for use when in use, or the heating speed of the heating mode selected by the user is too slow, the water is not heated until the water using time point, or the next specific water using time point is far away from the current time, the water heater is continuously opened but heating is not carried out, so that the electric quantity consumption is caused. Therefore, through the judgement to the water time point of prediction and/or water consumption, the different functional mode of automatic selection realizes intelligent control, need not user input selection or sends the selection command through APP, and it is more convenient to use, and is more energy-conserving.
The method for predicting the time point of next water consumption is the method described in the first embodiment to the second embodiment.
Further, the water heater is controlled to select different functional modes according to specific water using time points, including
The functional mode comprises a shutdown mode, and the data processing unit controls whether the water heater selects the shutdown mode or not according to the specific water using time point and the current time point.
After the water heater predicts the next specific water using time point, the prediction is more accurate, the interval between the next water using time and the current time can be directly judged, if the next specific water using time is longer than the current time, the water heater can be cooled and consumes no power when being used next time even if being heated, the water heater can be shut down firstly, the water heater is restarted when the time is proper, and if the time is closer, the heating mode which is consistent with the time can be selected. The whole control method is more intelligent and energy-saving by firstly judging whether the water heater is turned off.
Further, the data processing unit controls whether the water heater selects the shutdown mode or not according to the specific water using time point and the current time, including
