For example, the temperature detection device 400 may use the last detected temperature as the detected temperature, or may detect the last detected temperature for 5 times within 2 seconds, and then use the detection result of the 5 times as the detection value. It is worth to be noted that the technical scheme of the invention is suitable for water storage type water heaters, including electric heating water storage type, combustion heating water storage type and water storage type water heaters which use other energy sources for heating.
The following control method of a water heater proposed according to the above structure of the water heater includes the steps of:
s10: acquiring a current distance between a designated mobile terminal and a preset position;
in this embodiment, the preset location may be set according to a requirement of a user, so that there are many preset locations, for example, the preset location is set at home, or in a cell, or at an airport, or at a station, and the location of the water heater is taken as an example of the preset location.
The water heater and the designated mobile terminal are connected with the server through a wireless network. And the server calculates the distance between the water heater and the appointed mobile terminal according to the current positions of the water heater and the appointed mobile terminal. The water heater is internally provided with the wireless communication module, and the water heater and the wireless network are relatively fixed, so that the wireless communication module is directly connected into the wireless network as an example, in other embodiments, the connection between the wireless communication module and the wireless network can be set with a plurality of conditions or can be directly controlled by a user through an instruction. Similarly, the mode of the mobile terminal accessing the wireless network can be designated and can be always accessed to the wireless network or can be directly controlled by the user through an instruction. The designated mobile terminal can be an electronic product carried by a user, such as a mobile phone, a smart watch, a bracelet and the like.
And calculating the distance between the specified mobile terminal and the water heater, and specifically, the server can firstly acquire the specific positions of the water heater and the specified mobile terminal through a GPS positioning system. Of course, in some embodiments, the server may store the acquired location information of the water heater for the next direct call, in which case, in order to ensure the accurate location of the water heater, the location of the water heater in the server needs to be updated periodically. The server stores identification information of the water heater and the designated mobile terminal, so that the water heater and the designated mobile terminal can be in one-to-one correspondence. After the specific positions of the designated mobile terminal and the corresponding water heater are obtained, the distance between the designated mobile terminal and the water heater can be obtained through coordinate calculation. That is, the water heater obtains the current distance from the server, and the current distance is obtained by the server from the fixed position information of the water heater and the mobile position information of the specified mobile terminal, and is calculated and generated according to the fixed position information and the mobile position information. After the server acquires the coordinates of the water heater and the specified movement, the linear distance between the water heater and the specified movement can be calculated, or a route corresponding to a vehicle is planned according to the positions of the water heater and the specified movement, and then the distance corresponding to the route is calculated, wherein the vehicle can be an airplane, a high-speed rail, a self-driving vehicle and the like. Of course, it can be understood that, when planning a route, a corresponding map is required, and the map may be prestored in a designated mobile terminal or a water heater, or may be obtained from the internet. The map information can be updated in a timed and networking mode.
It is understood that there are many ways to determine the distance between the designated mobile terminal and the preset location, and besides the server mentioned in the above embodiment, the distance may also be a distance causing disconnection of a wireless local area network, a distance causing disconnection of a bluetooth, a distance causing disconnection of a wifi network in a home, or a distance calculated by the internet, etc.
The method for matching the water heater and the designated mobile terminal in the server can also be characterized in that the water heater stores the MAC address or other characteristic information of the designated mobile terminal, the water heater detects the characteristic information of the mobile terminal in the server through a wireless network, and then the acquired characteristic information is matched with the stored characteristic information of the designated mobile terminal. And the water heater acquires the position information of the specified mobile terminal only when the specified characteristic information is detected. And when the matching of the acquired feature information and the stored feature information of the specified mobile terminal fails, discarding the current matching object, and detecting and matching.
Because the designated mobile terminal is carried by the user, when the user goes out of work or goes on a business trip, the distance between the designated mobile terminal and the water heater is gradually increased along with the real-time update of the position of the designated mobile terminal in the server. When the user goes off work or goes home, the distance between the designated mobile terminal and the water heater is gradually reduced along with the real-time update of the position of the designated mobile terminal in the server.
Of course, in some embodiments, the designated mobile terminal and the water heater may be connected in a single direction, and the distance between the designated mobile terminal and the water heater is calculated by the micro server, and the micro server may be disposed in the designated mobile terminal or the water heater, at this time, the location information of the designated mobile terminal or the water heater does not need to be provided to a third party, which is beneficial to preventing the leakage of the location information of the user and improving the efficiency of the location calculation.
S20: and when the current distance between the appointed mobile terminal and the preset position is greater than or equal to the preset distance, the water heater is closed.
When the current distance between the appointed mobile terminal and the preset position is larger than or equal to the preset distance, the water heater is turned off, and excessive hot water is prevented from being heated. That is, when the current distance between the designated mobile terminal and the preset location is greater than or equal to the preset distance, it is considered that the user has been on work or on business, and the like, and at this time, the water heater needs to be turned off to avoid heating too much hot water. When the distance between the designated mobile terminal and the preset position is smaller than the second preset distance, the user is considered to be on the way home, and the water heater can be started at the moment. When the distance between the designated mobile terminal and the preset position is between the preset distance and a second preset distance, the water heater keeps the current working state, wherein the preset distance is greater than the second preset distance.
In the embodiment, firstly, the water heater detects a corresponding appointed mobile terminal, and obtains the current distance between the appointed mobile terminal and a preset position; when the current distance between the appointed mobile terminal and the preset position is larger than or equal to the preset distance, closing the water heater; among the above-mentioned technical scheme, the user leaves the back, and the water heater stops the heating very first time, has avoided the user to forget when going out to close the water heater, and leads to the water heater circulation heating to waste the energy, is favorable to the energy-conservation of water heater.
In order to more accurately turn off the water heater, the step of turning off the water heater when the current distance between the designated mobile terminal and the preset position is greater than or equal to the preset distance comprises:
when the current distance between the appointed mobile terminal and the preset position is larger than or equal to the preset distance, counting the water consumption times of each water consumption time period of each day in the previous period, and when the water consumption times of the water consumption time period are larger than or equal to the preset times, the time period is a regular time period;
in this embodiment, the cycle is exemplified by 21 days, and each day is divided into six time periods, which are respectively 3: 00-7: 00, 7: 00-11: 00, 11: 00-15: 00, 15: 00-19: 00, 19: 00-23: 00, 23: 00-3: 00. During each period, the number of times the user uses water, and the amount of water used per time, is recorded. The total number of water usage times in a water usage period is, the total number of water usage times in the water usage period in 21 days of a cycle, and the number of water usage times per day in each period may be different, for example, 7 on monday to friday: the average water consumption frequency of 00-11: 00 is 0.5, and the water consumption frequency of saturday and sunday is 7: the average water consumption frequency of 00-11: 00 is 3.5. The preset number is 11, for example, and may be set according to the requirement of the user in some embodiments. That is, when the user uses water for a certain period of time of 21 days for 11 times or more, the period is set as a regular period, and the water consumption is controlled to be increased by the period 19: 00-23: 00 as an example. When the user uses water less than 11 times in a certain period of 21 days, the period is set as an irregular period, and the period is set as a period of 11: 00-15: 00 as an example. The water consumption time period is divided into regular time periods and irregular time periods through statistics of the total water consumption times in the water consumption time period.
Of course, before statistics, the heating control needs to be periodically set, each period time length and water use time period are divided, and the water use condition of the user in each water use time period, namely the water use times, the water use frequency, the water use temperature and the water use amount, is recorded. This process, for the learning process of the water heater, in the first cycle, the water usage parameter not set by the user is installed with preset parameters for operation, for example, the heating time is preset to 19: 00-23: 00 and 7: 00-11: 00, presetting a sleep time period as 23: 00-3: 00, and the like. The second overtime period is set according to the water consumption condition of the first period of the user, and the third period is adjusted according to the water consumption conditions of the first period and the second period.
When the current time period is a regular time period, sending a confirmation request to the appointed mobile terminal; and when receiving the confirmation information sent by the mobile terminal, closing the water heater.
When the current time period is a regular time period, the frequency of water use by the user is high, and at this time, the user does not necessarily need to use hot water although the user is not at home. In order to improve the accuracy of the power supply, the water heater sends the preset request information to the specified mobile terminal through the wireless network, and of course, in other embodiments, the water heater may also be sent to the specified mobile terminal through a communication network (e.g., mobile, internet, telecommunication, etc.). And the appointed mobile terminal replies to the water heater according to the instruction of the user. When the user does not need to use hot water, the confirmation can be selected on the display interface of the designated mobile terminal, and when the user needs to use hot water, the cancellation or no indication can be selected on the display interface of the designated mobile terminal. And when the water heater receives the confirmation information sent by the appointed mobile terminal, the water heater is turned off to stop heating. When the water heater receives the negative information or does not receive the information sent by the appointed mobile terminal, the water heater keeps the existing state and is not closed.
In this embodiment, when it is detected that the distance between the designated mobile terminal and the water heater is greater than or equal to the preset distance, the designated mobile terminal is consulted instead of being directly powered off, and confirmation of the user is waited to avoid error power-off.
In order to increase the accuracy of turning off the water heater, the step of obtaining the current distance between the designated mobile terminal and the preset position specifically includes:
counting the water consumption times of each water consumption time period of each day in the previous period, wherein when the water consumption times of the water consumption time period are less than the preset times, the time period is an irregular time period;
in this embodiment, the cycle is exemplified by 21 days, and each day is divided into six time periods, which are respectively 3: 00-7: 00, 7: 00-11: 00, 11: 00-15: 00, 15: 00-19: 00, 19: 00-23: 00, 23: 00-3: 00. During each period, the number of times the user uses water, and the amount of water used per time, is recorded. The total number of water usage times in a water usage period is, the total number of water usage times in the water usage period in 21 days of a cycle, and the number of water usage times per day in each period may be different, for example, 7 on monday to friday: the average water consumption frequency of 00-11: 00 is 0.5, and the water consumption frequency of saturday and sunday is 7: the average water consumption frequency of 00-11: 00 is 3.5. The preset number is 11, for example, and may be set according to the requirement of the user in some embodiments. That is, when the user uses water for a certain period of time of 21 days for 11 times or more, the period is set as a regular period, and the water consumption is controlled to be increased by the period 19: 00-23: 00 as an example. When the user uses water less than 11 times in a certain period of 21 days, the period is set as an irregular period, and the period is set as a period of 11: 00-15: 00 as an example. The water consumption time period is divided into regular time periods and irregular time periods through statistics of the total water consumption times in the water consumption time period.
Of course, before statistics, the heating control needs to be periodically set, each period time length and water use time period are divided, and the water use condition of the user in each water use time period, namely the water use times, the water use frequency, the water use temperature and the water use amount, is recorded. This process, for the learning process of the water heater, in the first cycle, the water usage parameter not set by the user is installed with preset parameters for operation, for example, the heating time is preset to 19: 00-23: 00 and 7: 00-11: 00, presetting a sleep time period as 23: 00-3: 00, and the like. The second overtime period is set according to the water consumption condition of the first period of the user, and the third period is adjusted according to the water consumption conditions of the first period and the second period.
And when the current time period is an irregular time period, acquiring the current distance between the appointed mobile terminal and the preset position. In the embodiment, the distance between the water heater and the designated mobile terminal is not directly acquired by the water heater, the water consumption habit in the current time period is firstly judged according to the water consumption rule, and when the water consumption times in the current time period are less, the distance is acquired, so that the probability of mistakenly turning off the water heater is reduced, and the turning-off accuracy of the water heater is improved.
In order to further improve the shutdown accuracy, when the current time period is an irregular time period, the step of obtaining the current distance between the specified mobile terminal and the preset position specifically includes:
when the current time period is an irregular time period, calculating the average water consumption of all the irregular time periods, and when the water consumption of the irregular time period is less than or equal to the average water consumption, the irregular time period is a sleep time period;
in this embodiment, in the irregular time period, the water consumption of each water use in all the irregular time periods is counted, the total water consumption in all the irregular time periods is calculated, and then the total water consumption is divided by the number of the irregular time periods to obtain the average water consumption in the irregular time periods.
For example, the irregular time period is represented by 3: 00-7: 00, 11: 00-15: 00 and 23: three time periods of 00-3: 00 are taken as examples. First, 3: 00-7: 00, 11: 00-15: 00 and 23: calculating the water consumption of 00-3: 00 to serve as the daily water consumption in irregular time intervals, and adding the water consumption in 21 irregular time intervals in a cycle to obtain a time interval of 3: 00-7: 00, 11: 00-15: 00 and 23: and (3) dividing the total water consumption in the period of 00-3: 00 by the quantity of the irregular time periods 3 to obtain the average water consumption in the period of the irregular time periods. The average water consumption is 10L for example.
The average water usage is compared to the water usage over each irregular time period. Namely, the average water consumption is respectively compared with 21 water in the cycle, namely 3: the sum of water consumption of 00-7: 00, 21 water consumption of 11: the sum of water consumption of 00-15: 00, 21 water consumption of 23: and (5) comparing the sum of the water consumption of 00-3: 00. When the water consumption in a certain irregular time period is less than the average water consumption, the time period is a dormant time period. And (3) adding 23: 00-3: 00, if 21, 23: if the total water consumption in the time period of 00-3: 00 is less than or equal to the average water consumption, 23: 00-3: 00 is a sleep time period. When the water consumption in a certain irregular time period is larger than the average water consumption, the time period is a low-temperature time period. In a ratio of 11: 00-15: 00, if 21, 11: when the sum of the water consumption of 00-15: 00 is larger than the average water consumption, 11: and the low-temperature time period is 00-15: 00.
And when the current time period is the dormancy time period, acquiring the current distance between the appointed mobile terminal and the preset position. In the embodiment, the distance between the water heater and the designated mobile terminal is not directly acquired by the water heater, the water consumption habit in the current time period is firstly judged according to the water consumption rule, and when the water consumption times in the current time period are less, the distance is acquired, so that the probability of mistakenly turning off the water heater is reduced, and the turning-off accuracy of the water heater is improved.
The present invention further provides a water heater comprising:

in this embodiment, the water heater and the designated mobile terminal are both connected to the server through a wireless network. And the server calculates the distance between the water heater and the appointed mobile terminal according to the current positions of the water heater and the appointed mobile terminal. The water heater is internally provided with the wireless communication module, and the water heater and the wireless network are relatively fixed, so that the wireless communication module is directly connected into the wireless network as an example, in other embodiments, the connection between the wireless communication module and the wireless network can be set with a plurality of conditions or can be directly controlled by a user through an instruction. Similarly, the mode of the mobile terminal accessing the wireless network can be designated and can be always accessed to the wireless network or can be directly controlled by the user through an instruction. The designated mobile terminal can be an electronic product carried by a user, such as a mobile phone, a smart watch, a bracelet and the like.
And calculating the distance between the specified mobile terminal and the water heater, and specifically, the server can firstly acquire the specific positions of the water heater and the specified mobile terminal through a GPS positioning system. Of course, in some embodiments, the server may store the acquired location information of the water heater for the next direct call, in which case, in order to ensure the accurate location of the water heater, the location of the water heater in the server needs to be updated periodically. The server stores identification information of the water heater and the designated mobile terminal, so that the water heater and the designated mobile terminal can be in one-to-one correspondence. After the specific positions of the designated mobile terminal and the corresponding water heater are obtained, the distance between the designated mobile terminal and the water heater can be obtained through coordinate calculation. Namely, the acquisition module includes: a second obtaining unit configured to obtain the current distance from the server; the server acquires the fixed position information of the water heater and the mobile position information of the designated mobile terminal, and the current distance is calculated and generated according to the fixed position information and the mobile position information.
The method for matching the water heater and the designated mobile terminal in the server can also be characterized in that the water heater stores the MAC address or other characteristic information of the designated mobile terminal, the water heater detects the characteristic information of the mobile terminal in the server through a wireless network, and then the acquired characteristic information is matched with the stored characteristic information of the designated mobile terminal. And the water heater acquires the position information of the specified mobile terminal only when the specified characteristic information is detected. And when the matching of the acquired feature information and the stored feature information of the specified mobile terminal fails, discarding the current matching object, and detecting and matching.

in this embodiment, the cycle is exemplified by 21 days, and each day is divided into six time periods, which are respectively 3: 00-7: 00, 7: 00-11: 00, 11: 00-15: 00, 15: 00-19: 00, 19: 00-23: 00, 23: 00-3: 00. During each period, the number of times the user uses water, and the amount of water used per time, is recorded. The total number of water usage times in a water usage period is, the total number of water usage times in the water usage period in 21 days of a cycle, and the number of water usage times per day in each period may be different, for example, 7 on monday to friday: the average water consumption frequency of 00-11: 00 is 0.5, and the water consumption frequency of saturday and sunday is 7: the average water consumption frequency of 00-11: 00 is 3.5. The preset number is 11, for example, and may be set according to the requirement of the user in some embodiments. That is, when the user uses water for a certain period of time of 21 days for 11 times or more, the period is set as a regular period, and the water consumption is controlled to be increased by the period 19: 00-23: 00 as an example. When the user uses water less than 11 times in a certain period of 21 days, the period is set as an irregular period, and the period is set as a period of 11: 00-15: 00 as an example. The water consumption time period is divided into regular time periods and irregular time periods through statistics of the total water consumption times in the water consumption time period.
Of course, before statistics, the heating control needs to be periodically set, each period time length and water use time period are divided, and the water use condition of the user in each water use time period, namely the water use times, the water use frequency, the water use temperature and the water use amount, is recorded. This process, for the learning process of the water heater, in the first cycle, the water usage parameter not set by the user is installed with preset parameters for operation, for example, the heating time is preset to 19: 00-23: 00 and 7: 00-11: 00, presetting a sleep time period as 23: 00-3: 00, and the like. The second overtime period is set according to the water consumption condition of the first period of the user, and the third period is adjusted according to the water consumption conditions of the first period and the second period.
A request unit 22, configured to send a confirmation request to a specified mobile terminal when the current time period is a regular time period; and the closing unit 23 is used for closing the water heater when receiving the confirmation information sent by the mobile terminal.
When the current time period is a regular time period, the frequency of water use by the user is high, and at this time, the user does not necessarily need to use hot water although the user is not at home. In order to improve the accuracy of the power supply, the water heater sends the preset request information to the specified mobile terminal through the wireless network, and of course, in other embodiments, the water heater may also be sent to the specified mobile terminal through a communication network (e.g., mobile, internet, telecommunication, etc.). And the appointed mobile terminal replies to the water heater according to the instruction of the user. When the user does not need to use hot water, the confirmation can be selected on the display interface of the designated mobile terminal, and when the user needs to use hot water, the cancellation or no indication can be selected on the display interface of the designated mobile terminal. And when the water heater receives the confirmation information sent by the appointed mobile terminal, the water heater is turned off to stop heating. When the water heater receives the negative information or does not receive the information sent by the appointed mobile terminal, the water heater keeps the existing state and is not closed.
In this embodiment, when it is detected that the distance between the designated mobile terminal and the water heater is greater than or equal to the preset distance, the designated mobile terminal is consulted instead of being directly powered off, and confirmation of the user is waited to avoid error power-off.
To increase the accuracy of turning off the water heater, the acquisition module includes:
the second statistical unit is used for counting the water consumption times of each water consumption time period of each day in the previous period, and when the water consumption times of the water consumption time periods are smaller than the preset times, the time periods are irregular time periods;
in this embodiment, the cycle is exemplified by 21 days, and each day is divided into six time periods, which are respectively 3: 00-7: 00, 7: 00-11: 00, 11: 00-15: 00, 15: 00-19: 00, 19: 00-23: 00, 23: 00-3: 00. During each period, the number of times the user uses water, and the amount of water used per time, is recorded. The total number of water usage times in a water usage period is, the total number of water usage times in the water usage period in 21 days of a cycle, and the number of water usage times per day in each period may be different, for example, 7 on monday to friday: the average water consumption frequency of 00-11: 00 is 0.5, and the water consumption frequency of saturday and sunday is 7: the average water consumption frequency of 00-11: 00 is 3.5. The preset number is 11, for example, and may be set according to the requirement of the user in some embodiments. That is, when the user uses water for a certain period of time of 21 days for 11 times or more, the period is set as a regular period, and the water consumption is controlled to be increased by the period 19: 00-23: 00 as an example. When the user uses water less than 11 times in a certain period of 21 days, the period is set as an irregular period, and the period is set as a period of 11: 00-15: 00 as an example. The water consumption time period is divided into regular time periods and irregular time periods through statistics of the total water consumption times in the water consumption time period.
Of course, before statistics, the heating control needs to be periodically set, each period time length and water use time period are divided, and the water use condition of the user in each water use time period, namely the water use times, the water use frequency, the water use temperature and the water use amount, is recorded. This process, for the learning process of the water heater, in the first cycle, the water usage parameter not set by the user is installed with preset parameters for operation, for example, the heating time is preset to 19: 00-23: 00 and 7: 00-11: 00, presetting a sleep time period as 23: 00-3: 00, and the like. The second overtime period is set according to the water consumption condition of the first period of the user, and the third period is adjusted according to the water consumption conditions of the first period and the second period.
