Definitions

  • a method for automatically controlling a water heater including:
  • the amount of water in the different periods shown above may be the amount of water under different temperature conditions.
  • the amount of water in the time period of 12:00-14:00 and the time period of 20:00-22:00 may correspond to different inlet water temperatures and intra-tank temperatures.
  • no attention is paid to the difference between the inlet water temperature and the intra-tank temperature, and the corresponding setting temperature is predicted at different periods based on the amount of water.
  • the amount of water under different temperature conditions is unified to the amount of water under the standard-temperature, referred to as the amount of used standard-temperature water, which is explained in other subsequent embodiments.
  • the setting temperature of the water heater at different periods in a future water usage process is predicted and thus a method for automatically controlling the water heater capable of being adaptive to a water usage behavior of a user, which not only solves the problem that a user manually reserves the temperature of the water heater, but also may allow the water heater to operate in a manner of low energy consumption under the premise of ensuring the water demand, thereby intelligently controlling the water heater.
  • the step 101 of determining the amount of water used at different periods in a historical water usage process includes the following steps: step 101': determining the amount of standard-temperature water used at different periods in the historical water usage process; wherein the amount of used standard-temperature water is obtained by converting the amount of water under different temperature conditions into the amount of used water at the standard-temperature.
  • the step 102' of determining the amount of standard-temperature water that the water heater can supply at different setting temperatures includes the following steps:
  • the processing methods of steps B1-B2 are adopted.
  • the amount of water supplied at different setting temperatures may be converted to the amount of used standard-temperature water by using the model of the second preset amount of used standard-temperature water and thus the amount of standard-temperature water supplied at the different setting temperatures are obtained. Therefore, more accurate matching result may be obtained when the amount of standard-temperature water supplied at different setting temperatures is matched with the amount of standard-temperature water used at different periods in a historical water usage processes.
  • the step 103 of predicting a setting temperature of the water heater at different periods in a future water usage process, based on the amount of water used at different periods in a historical water usage process and the amount of water that the water heater can supply at different setting temperatures specifically includes: step 103': predicting a setting temperature of the water heater at different periods in a future water usage process, based on the amount of standard-temperature water used at different periods in a historical water usage process and the amount of standard-temperature water that the water heater can supply at different setting temperatures.
  • the amount of standard-temperature water used at different periods in a historical water usage process and the amount of standard-temperature water that the water heater can supply at different setting temperatures are obtained and thus the setting temperature of the water heater at different periods in a future water usage process is predicted by mapping the amount of used standard-temperature water with each other based on the amount of standard-temperature water used at different periods in a historical water usage process and the amount of standard-temperature water that the water heater can supply at different setting temperatures.
  • the amount of standard-temperature water that the water heater can supply is greater than or equal to the amount of standard-temperature water used at a corresponding period in the historical water usage process and needs to be closest to the amount of standard-temperature water used the corresponding period in historical water usage process.
  • the amount of standard-temperature water used at the corresponding period in historical water usage process may be further discretized using the amount of water difference between the amount of water may be supplied at two setting temperatures and thus the influence of abnormal sensor data on results.
  • the amount of standard-temperature water that may be supplied at 40°C setting temperature is 10 liters and the amount of water that can be supplied at 45°C setting temperature is 15 liters
  • the setting temperature corresponding to the different periods of each day in the historical water usage days is first determined based on the amount of standard-temperature water used at different periods of the day in the historical water usage days and the amount of standard-temperature water that the water heater can supply at the different setting temperatures and the setting temperature of the water heater at different periods of each day in the future water usage process may be predicted based on the setting temperature of the water heater corresponding to the different periods of each day in the historical water usage days.
  • the temperature voting mechanism is used to determine the setting temperature of the water heater at different periods of a day in a future water usage process.
  • a probability threshold can be set. The larger the probability threshold, the lower the tolerance for small-probability water usage events. For example, for setting temperatures (setting temperatures matched well in step 103)) in a certain period, i.e., past six days, a voting mechanism is used to vote against a setting temperature that should be set for this time period in the next day.
  • the voting mechanism here refers to transmitting the setting temperature of the water heater at different periods in the past 6 days to a use device, and then allowing the user to vote against the setting temperature of the water heater at different periods in past 6 days separately.
  • the setting temperature corresponding to the period of 00:00-02:00 in past 6 days is 40°C, 40°C, 45°C, 45°C, 40°C, 40° C, 40° C
  • these setting temperatures are then transmitted to the user and the user votes against these setting temperatures, and the final statistical voting result includes: 5 votes for 40°C setting temperature and 1 vote for 45°C setting temperature.
  • the highest gear of all the historical corresponding setting temperatures is selected as the predicted setting temperature at the period of next day. For example, for the period of 00:00-02:00 in six days of the above example, the 45°C setting temperature is selected as the predicted setting temperature at the period of next day.
  • the probability threshold is used as the predicted setting temperature, such that the predicted setting temperature can meet the user's water usage behavior with the greatest probability.
  • the probability of occasional water usage events is estimated, and tolerance of minor-probability water usage events is controlled by controlling the probability threshold parameter.
  • the step C2 of predicting a setting temperature of the water heater at different periods of a day in a future water usage process, based on the setting temperature of the water heater at different periods of a day in historical water usage days specifically includes:
  • the present embodiment does not need to use a voting mechanism, but directly uses the highest setting temperature among all setting temperatures under different historical water usage days corresponding to each time period as the predicted value of the setting temperature at different periods of the day in future water usage process, so as to ensure that the predicted setting temperature can meet the user's water demand with the greatest probability.
  • the method for automatically controlling the water heater further includes:
  • the method for automatically controlling the water heater further includes:
  • the power costs that can be saved after implementing the method for automatically controlling the water heater control according to the present embodiment are further given, so that the user can intuitively see the saved power, thereby improving user experience.
  • the original setting temperature data before the water heater is turned on is recorded (if it is not turned on, the water heater will be heated and kept at the original setting temperature).
  • the water heater is automatically adjusted based on the predicted setting temperature output in the present embodiment.
  • the original setting temperature, the predicted setting temperature output in the present embodiment, the ambient temperature and the water usage data are used to estimate saved power after the water heater is turned on by a fitting equation.
  • a heating time of the water heater, a rated power of the water heater and the data of the ladder-type pricing data in the local area are obtained, and the consumed power during the operation of the water heater is calculated.
  • Pricing 1 and pricing 2 are ladder-type pricing.
  • a certain degree of data loss can also be tolerated because the user's water usage habits in a certain period have no change in a short period, so even if the data of a certain period of a day is missing, it will not have significant influence on the final prediction result.
  • a certain degree of abnormal value can also be tolerated because the amount of actually used standard-temperature water is discretized by using the amount of standard-temperature water corresponding to a temperature section, which can effectively avoid influence of very large or very small abnormal value on the results.
  • a device for automatically controlling a water heater includes: a first determiner11, a second determiner 12, a predictor 13 and controller 14, where
  • the device for automatically controlling a water heater according to the present embodiment can be used to implement the method for automatically controlling a water heater described in the foregoing embodiment, it has similar working principles and beneficial effects to the method, so that they will not be described in detail here, and the specific content can be referred to the introduction of the foregoing embodiment.

  • the water heater according to the present embodiment includes the device for automatically controlling a water heater according to the above embodiment, it has similar working principles and beneficial effects to the method, so that they will not be described in detail here, and the specific content can be referred to the introduction of the foregoing embodiment.
  • an electronic device in yet another embodiment of the present application, specifically includes: a processor 301, a memory 302, a communication interface 303, and a bus 304;
  • the electronic device mentioned in the present embodiment may be a mobile terminal or a cloud server.
