Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
The control method of the water heater in the embodiment comprises the following steps:
step S1, storing the on/off state of the water heater in the appointed time and the temperature setting data of the water heater by the user;
step S2, establishing a user behavior database of the water heater by the user according to the on/off state of the water heater in the appointed time and the temperature setting data of the water heater by the user;
step S3, when the appointed time is over, the water heater judges whether the water heater is in the power-on state or the power-off state in the next time period according to the current user behavior database;
step S4, when it is determined that the water heater should be turned on in the next current time period, the water heater is turned on and the output temperature corresponding to the water heater in the time period is set according to the current user behavior database.
At present, the water heater is mainly controlled by a user manually, the starting heating, the water temperature, the use mode and the like are set, and the intelligent degree is low; moreover, the set humidity and state of the water heater cannot change along with the change of the environment, and the temperature and state suitable for the current environment need to be reset by a user after a period of time, so that inconvenience is brought to the user.
The technical scheme aims to realize automatic control of the water heater through the habit of a system self-learning user for using the water heater, and comprises the following steps:
step S1, storing the on/off state of the water heater in the appointed time and the temperature setting data of the water heater by the user; in order to better grasp the behavior habit of a user on the water heater, the system firstly stores the on/off state of the water heater in a specified time and the temperature setting data of the water heater by the user. Specifically, the setting of the on/off state of the water heater and the temperature setting data of the water heater by the user are set by the user according to a setting method recorded in a user manual, for example, the user can set the on/off state of the water heater and adjust the temperature of the water heater in sequence through key input according to a method recorded in a water heater use instruction, or can set corresponding instructions correspondingly according to information prompted by voice through touch screen input according to information prompted by a screen that the water heater can be contacted with the screen.
Step S2, establishing a user behavior database of the water heater by the user according to the on/off state of the water heater in the appointed time and the temperature setting data of the water heater by the user; the method comprises the steps that a user behavior database is formed by collecting the on/off state of a water heater and the temperature setting data of a user on the water heater in a specified time; according to the using rule of the water heater by the user, the user behavior can be effectively predicted, and the water heater can be intelligently controlled.
Step S3, when the appointed time is over, the water heater judges whether the water heater is in the power-on state or the power-off state in the next time period according to the current user behavior database; (ii) a The control of the water heater is that firstly, the system predicts that the water heater is in a starting state or a shutdown state in the current next time period according to a user behavior database. For example, in each time period within 1 day, the user may not need to use the water heater in the time period of going out at work, but needs to use the water heater after going home at night, and this habit is recorded by the system at steps S1 and S2, and a user behavior database is formed. When the system predicts whether the user needs to use the water heater in a certain time period, the user behavior database which is recorded and formed can be used for judging whether the water heater is in a starting state or a shutdown state in the next time period. When a user hurries to work, the situation that the user forgets to turn off the water heater can occur, and by the control method, the switch of the water heater is intelligently controlled, so that the waste of energy sources is avoided, and the satisfaction degree of the user is greatly improved.
And step S4, when the water heater is judged to be in the starting state in the next current time period, the water heater is started and the corresponding output temperature of the water heater in the time period is set according to the current user behavior database. When the system judges that the water heater is in the starting state within a certain time period, the system needs to predict the output temperature of the water heater when the water heater is in the starting state. Because the water heater needs a certain time to heat, in order to ensure that when a user needs to use the water heater, the water heater can immediately have water with adaptive temperature for the user to use, the temperature control is additionally arranged. When the water heater is in the starting state, the water heater can predict the output temperature of the water heater in the current time period according to the current user behavior database. For example, during the time interval of 7-8 am in winter, when the water heater is set to be in the on state by the user and the temperature is set to be 30 ℃ for the user to wash in the morning, the control system sets the water heater to be in the on state and heats the water to 30 ℃ during the time interval of 7-8 am in the next day according to the stored user behavior database. Therefore, the user can wash the face and rinse the mouth in the morning immediately after getting out of bed without the need that the user opens the water heater first, then sets the temperature to be 30 ℃, and also waits for the water temperature to be heated and then washes the face and rinses the mouth in the morning, so that the time of the user is saved, the control of the water heater is closer to the life, and the satisfaction degree of the user is improved.
The technical scheme effectively predicts the user behavior through self-learning of the user behavior, and the specific expression is as follows: firstly, a user does not need to repeatedly open and close the water heater and set the temperature, and the traditional control method brings great inconvenience to the user, lacks of intellectualization and cannot realize automatic control; secondly, the water heater is turned off and on in time, so that the waste of electric energy is avoided; and thirdly, the water heater is started to reach the temperature required by the user for bathing after waiting for a period of time, the requirement of immediately bathing cannot be met, the temperature control is additionally arranged on the water heater, the intelligent control on the water heater is realized, and the user satisfaction is improved.
Further, step S1 specifically includes the following steps:
s10, dividing 1 day into a plurality of time periods;
and S11, recording the on/off state of the water heater and the temperature setting data of the water heater by the user when the time period is entered.
Step S1 specifically includes the following steps:
s10, dividing 1 day into a plurality of time periods; the setting of the time interval in the time period can be set by the user according to the actual situation of the user and according to the setting method described in the user manual, for example, the user can divide 1 day into 24 time periods, wherein the ratio of 0: 00-1: 00 is the 1 st time period of the day, from 1: 00-2: 00 is the 2 nd time period … … of the day and so on. If the service time interval of the water heater is short according to the use habits of users, 1 day can be divided into 48 time periods, wherein the ratio of 0: 00-0: 30 is the 1 st time period of the day, from 0: 30-1: 00 is the 2 nd time period … … of the day and so on.
And S11, recording the on/off state of the water heater and the temperature setting data of the water heater by the user when the time period is entered. Because there is a certain time interval in a time period, when the system stores the on/off state of the water heater and the temperature setting data of the water heater by the user in each time period, the moment of entering the time period is recorded, namely when 1 day is divided into 24 time periods, wherein the time period is from 0: 00-1: 00 is the 1 st time period of the day, and would record 0: the on/off state of the water heater at 00 hours and the temperature setting data of the water heater by a user are convenient to record, and the system is easy to analyze and timely to judge.
To be more specific, step S1 further includes the following steps:
s12, collecting the on/off state of the water heater and the temperature setting data of the water heater by the user in each time period of N days, and performing the step S2 when N is more than or equal to 10;
step S2 specifically includes the following steps:
s20, calculating the use frequency P [ i ] open of the water heaters in the same time period in N days;
s21, calculating a weighted average value of the temperature setting data of the water heaters in the same time period in N days, wherein the weighted average value of the temperature setting data is the output temperature T [ i ] old corresponding to the water heaters in the same time period;
s22, establishing a user behavior database in each time period, wherein the user behavior database is the use frequency P [ i ] open of the water heater and the weighted average T [ i ] old of the temperature setting data in each time period.
Step S1 further includes the steps of:
s12, collecting the on/off state of the water heater and the temperature setting data of the water heater by the user in each time period of N days, and performing the step S2 when N is more than or equal to 10; the system needs to record the on/off state of the water heater and the temperature setting data of the water heater by the user in each time period of N days, for the same time period of N days, the water in the time period of 1 day may be used due to different behavior habits of the user, the water in the same time period of 2 days is not used, the body state of the user is different due to different environmental temperatures of each day, the water temperature required to be set is different, and the optimal water temperature for the water use of the user is set by the user. The free setting of the on/off state and the water temperature of the water heater is beneficial to meeting the requirements of a user on water use in different time periods, and the user experience is improved. Specifically, the on/off state of the water heater and the water temperature set by the user need to be recorded more than 10 times, so that the user behavior database is more representative.
Step S2 specifically includes the following steps:
s20, calculating the use frequency P [ i ] open of the water heaters in the same time period in N days; for example, 1 day is divided into 24 time periods, whether the time period is a startup time period or a shutdown time period is predicted according to the use frequency P [ i ] open of a certain time period of a user, wherein the use frequency P [ i ] open is di [ i ] open 100%/N, D [ i ] open is the number of days for starting up the certain time period in N days of the water heater, i represents the ith time period of 1 day, i is 0,1,2 … …, 24, and the use frequency P [ i ] open is used as the judgment condition of the startup/shutdown state of the water heater, so that the method is simple and reasonable and can effectively judge the use condition of the water heater.
S21, calculating a weighted average value of the temperature setting data of the water heaters in the same time period in N days, wherein the weighted average value of the temperature setting data is the output temperature T [ i ] old corresponding to the water heaters in the same time period; specifically, Ti old represents that the water heater is in a starting state, the user manually sets a weighted average value of water temperature values in the ith time period of 1 day and continuously stores temperature setting data for more than 10 times in the ith time period of N days, so that a user behavior database is more representative, the size of the weighted average value is not only dependent on the size of the temperature data set each time in the population but also dependent on the number of times of occurrence of the temperature setting data each time, therefore, the weighted average value of the temperature setting data in the same time period of N days is taken as the output temperature Ti old in the time period, and the behavior habit of the user can be better reflected on a control system.
S22, establishing a user behavior database in each time period, wherein the user behavior database is the use frequency P [ i ] open of the water heater in each time period and the weighted average T [ i ] old of the temperature setting data when the water heater is in the starting state. The use frequency P [ i ] open of the water heater and the weighted average T [ i ] old of the temperature setting data when the water heater is in the starting state are used as the behavior information of the user behavior database, so that the method is simple and reasonable, the user behavior can be effectively predicted, and the user experience is improved.
Further, the specific steps in step S3 are:
when P [ i ] open is more than or equal to P, judging that the next time period of the water heater is in a starting state, wherein P is a starting frequency threshold of the water heater;
when Pi open is less than or equal to q, judging that the next time period of the water heater is in a shutdown state, wherein q is a shutdown frequency threshold of the water heater;
when P [ i ] open < P or P [ i ] open > q, the water heater is judged to maintain the original on/off state.
The specific steps in step S3 are:
when Pi open is not less than P, judging that the next time period of the water heater is in a starting state;
when Pi open is less than q, judging that the next time section of the water heater is in a shutdown state;
for example, during winter, the user is 7: 00-8: the water heater is used for 8 days in the time period of 00, but is not used for 2 days, and the situation that the water heater is not used for 2 days due to the fact that the water heater is used for 2 days after getting up late and is not used for enough time may occur. According to the normal habit of the user, the user needs to use the method in the time period, and the method can not be used normally only because of the occurrence of emergency. In order to avoid the occurrence of the few and sudden situations, the control system provides a judgment threshold value which comprises a starting frequency threshold value P and a shutdown frequency threshold value q, when Pi open is not less than P, the next time section of the water heater is judged to be in the starting state, and when Pi open is not more than q, the next time section of the water heater is judged to be in the shutdown state; when P [ i ] open < P or P [ i ] open > q, the water heater is judged to maintain the original on/off state. Specifically, a user can set a starting frequency threshold value p and a shutdown frequency threshold value q according to the actual situation of the user and the instruction information of the user manual, wherein the starting frequency threshold value p and the shutdown frequency threshold value q can be the same or different, so that the control logic of the water heater is better close to life, and the user experience is improved.
Preferably, the specific steps in step S3 are:
when Pi open is greater than 80%, judging that the next time segment of the water heater is in the on state;
when Pi open is less than 20%, judging that the next time section of the water heater is in a shutdown state;
when P [ i ] open is less than 80% or P [ i ] open is more than 20%, the original on/off state of the water heater is judged.
More specifically, step S4 is followed by the following steps:
if the user changes the on/off state of the water heater in the current time period, the step S1 is repeated.
The method further comprises the following steps after the step S4:
when the system judges that the current time period of the water heater is the starting time period according to the user behavior database and the starting temperature is 30 ℃, the situation that the water heater cannot be used due to the fact that the user temporarily goes out or is delayed by other things may occur, in order to save energy, the user may change the starting/stopping state of the water heater in the current time period, the step S1 is repeated, and it is ensured that each control information changed by the user is recorded by the system, so that the user behavior database is fitted better from the behavior habit of the user, and the user behavior is further predicted.
More specifically, step S4 is followed by the following steps:
if the temperature T [ i ] old corresponding to the water heater in the current time period does not meet the water demand of the user, the user resets the temperature setting data T [ i ] user for the water heater, the water heater recalculates the output temperature T [ i ] now of the water heater according to the T [ i ] old and the T [ i ] user, and the step S1 is repeated;
specifically, T [ i ] now ═ 1-k × T [ i ] old + k × T [ i ] user, where k denotes the update weight set by the user for T [ i ] user.
The method further comprises the following steps after the step S4:
if the temperature T [ i ] old corresponding to the water heater in the current time period does not meet the water demand of the user, specifically, the user can reset the temperature setting data T [ i ] user for the water heater due to sudden change of the environment temperature or sudden discomfort of the body state of the user, the water heater recalculates the output temperature T [ i ] now of the water heater according to the T [ i ] old and the T [ i ] user, and repeats the step S1 to update the user behavior database, so that each piece of control information changed by the user is ensured to be recorded by the system, the user behavior database is fitted from the user behavior habit better, and the user behavior is predicted further.
Specifically, the step of determining the updated set temperature T [ i ] now is performed according to the following method according to the initial set temperature T [ i ] old, the user updated set temperature T [ i ] user, and the updated temperature weight k:
T[i]now＝(1-k)×T[i]old+k×T[i]user；
i denotes the ith time period of the day, where i is 0,1,2 … …
T [ i ] old represents the water temperature value originally set by the program in the ith time period of 1 day in the starting state, the initial value is set as the water heater used by the user for the first time, and the weighted average value of the water temperature value is manually set by the user in a certain time period within N days;
ti now represents the set water temperature value of program update in the ith time interval of 1 day under the starting state;
t [ i ] user represents that in the starting state, in the ith time interval of 1 day, a user manually sets a water temperature value;
k represents the updating weight set by the user T [ i ] user, the relationship between the updating weight and the updating frequency is k ═ N [ i ]/N, N represents the number of cache record days, N [ i ] represents the number of times the user manually updates the water temperature value in the ith time period in the cache record, for example, in 10 days, the user updates the water temperature value 5 times in a certain time period, N ═ 10, N [ i ] ═ 5, and the updating weight k is 0.5. The updated set temperature T [ i ] now is determined through the initial set temperature T [ i ] old, the user updated set temperature T [ i ] user and the updated temperature weight k, so that the water temperature setting of the water heater is more practical and humanized.
