At present, water source supplement and temperature adjustment of the solar water heater are controlled manually, and water consumption experience of people is difficult to ensure.
The existing solar water heater for realizing intelligent control judges the activity state of a user through the heart rate measured by a human body signal collecting unit on the user, predicts the bathing behavior of the user by combining the skin surface state of the user, and automatically adjusts the water supply temperature of the solar water heater according to the bathing behavior of the user. In the prior art, the solar water heater is controlled by predicting the user behavior, so that the hot water supplied by the solar water heater is difficult to ensure that the hot water can meet the user demand at any time, and the water consumption experience of a user is influenced. Therefore, there is a need for a solar water heater control and regulation system.
Disclosure of Invention
The present invention aims to solve at least one of the technical problems existing in the prior art; therefore, the invention provides a solar water heater control and regulation system which is used for solving the technical problems that in the prior art, the solar water heater is controlled only by predicting the water consumption behavior of a user, the all-weather water consumption requirement of the user is difficult to ensure, and the water consumption experience of the user is influenced.
In order to achieve the above object, a first aspect of the present invention provides a solar water heater control and regulation system, which includes a central control module, and a data acquisition module and a water supply control module connected with the central control module; the central control module collects historical water use data through the data acquisition module, performs division statistics on the historical water use data of each day according to a set period, and generates a water use time sequence by combining weather prediction data; wherein, the historical water consumption data comprises a climate environment and a water consumption moment, and the set period comprises one minute or one hour; the central control module determines the latest water use time according to the water use time sequence and marks the latest water use time as a target time; and controlling the solar water heater to heat the stored water; identifying whether the water supply temperature of the solar water heater at the target moment meets the requirement; the solar water heater stops heating the stored water and converts solar energy into electric energy for storage; and if not, heating the stored water by using the solar water heater or the stored electric energy.
The central control module controls the solar water heater from a global angle and mainly performs data interaction with the data acquisition module and the water supply control module. The data acquisition module is responsible for acquiring historical water consumption data of users and other users, wherein the historical water consumption data does not relate to personal privacy; the data acquisition module is also connected with the meteorological platform and used for acquiring weather prediction data of the area where the solar water heater is located. The water supply control module provides hot water to the user under the control of the central control module, and of course also detects heating in some cases prior to hot water supply. The weather environment and the weather forecast data have the same content attribute and comprise data such as temperature or humidity which influences the water supply temperature of the solar water heater.
When the solar water heater works, after the water supply temperature is set, the solar water heater starts to work when the illumination intensity meets the requirement, and the stored water is continuously heated, so that the stored water temperature can be overhigh; and when the illumination intensity does not meet the condition, the water storage temperature cannot meet the requirement of water supply temperature. Even though the solar water heater is intelligently modified at present, a plurality of types of sensors are still needed to be matched, so that the solar water heater is inconvenient to use and privacy leakage is possibly caused.
According to the method, historical water consumption data obtained through various compliance ways are used for analyzing and judging which time of the day a user needs to use hot water in the solar water heater, then whether the water supply temperature of the solar water heater can meet the requirement when the user needs to use water is analyzed, and if not, stored water is heated; in addition, when the stored water reaches the water supply temperature, the invention converts redundant solar energy into electric energy for storage, and can ensure the temperature of the stored water all weather.
Preferably, the dividing statistics is performed on the historical water consumption data of each day according to a set period, and the generating the water consumption time sequence by combining the weather prediction data includes: identifying whether historical water consumption data of a user meets requirements; if yes, dividing the historical water consumption data of each day according to a set period, and acquiring a water consumption time sequence by combining weather prediction data; if not, the next step is carried out; and supplementing historical water consumption data, generating a water consumption time sequence based on the set period and the weather prediction data, and acquiring a plurality of water consumption time sequences.
To determine when a user will use water, it is preferable to extract from the user's own historical water usage data. Therefore, whether the historical water consumption data of the user meets the requirement is judged firstly, and after the historical water consumption data meets the requirement, the probability of the user for water consumption in each period is obtained through statistical analysis based on the historical water consumption data of the user; otherwise, it is necessary to supplement with historical water usage data of other users in the same area to ensure the reliability of the water usage time series.
Preferably, the identifying whether the historical water usage data of the user meets the requirement includes: setting a time span of a water time sequence; and when the ratio of the time span of the historical water use data to the time span of the water use time sequence is larger than a preset multiple and the total number of the historical water use data is larger than a preset number, judging that the historical water use data meets the requirement.
The time span of the water use time series comprises one day or one week, and the time span is the duration corresponding to each water use time series. If the time span is one day, it can be understood that it is determined in the future which time period the user will use water in the day according to the historical water use data. Therefore, there is a demand for the number of the historical water use data, and the present invention judges whether the historical water use data (here, the historical water use data of the user) satisfies the demand or not mainly from the time span. If the requirements are met, the water use time series is generated by historical water use data of the user, otherwise, the water use time series is generated by combining the historical water use data of other users.
Preferably, the dividing the historical water consumption data of each day according to the set period, and acquiring the water consumption time sequence in combination with the weather prediction data, includes: dividing historical water use data of each day based on a set period to obtain a plurality of data segments; after the historical water consumption data are all divided, a water consumption climate threshold value corresponding to a set period is obtained based on the climate environment and a plurality of data segments, and a water consumption time sequence is obtained by combining weather prediction data.
The set period is less than the time span of the water use time series. The historical water consumption data of each day can be divided into a plurality of data segments through a set period, and the time span corresponding to the historical water consumption data is assumed to be 30 days, after the complete division of the historical water consumption data, each set period corresponds to 30 data segments, the water consumption climate threshold can be analyzed and extracted according to the water consumption behaviors in the 30 data segments, and the water consumption time sequence can be generated by combining weather prediction data. The water climate threshold value in the invention is used for distinguishing the climate environment in which water use behavior can exist for a user.
Preferably, the supplementing historical water use data, generating a water use time series based on the set period and the weather prediction data, and obtaining a plurality of water use time series includes: when the historical water consumption data of the user does not meet the requirement, acquiring the historical water consumption data of other users in the same area with the user based on a cloud technology to supplement the historical water consumption data of the user; dividing historical water use data of each day based on a set period to obtain a plurality of data segments; and acquiring a water consumption climate threshold value corresponding to the set period based on the climate environment and a plurality of data segments, and acquiring a water consumption time sequence by combining weather prediction data.
When the historical water consumption data of the user cannot meet the requirement, the historical water consumption data of other users in the area can be supplemented for evaluation. The area mainly refers to an area with similar climatic environments and similar living habits, and historical water consumption data of other users in the area has more reference value. The supplemented historical water consumption data can meet the requirement of the time span, and certainly, the water consumption climate threshold values of all set periods can be obtained according to the water consumption behaviors of a plurality of users in the same day, so that a water consumption time sequence is generated.
Preferably, the acquiring the water consumption climate threshold value corresponding to the set period based on the climate environment and the data segments, and acquiring the water consumption time sequence in combination with the weather prediction data includes: extracting a plurality of data segments corresponding to the set period, and determining a water climate threshold value when water behavior exists by combining climate environments corresponding to the data segments; and comparing the weather prediction data with a water consumption weather threshold value, judging whether water consumption behavior occurs in each set period, and integrating the judging result to generate a water consumption time sequence.
The water climate threshold value comprises temperature or humidity, whether water behavior exists in a corresponding set period is judged, when the temperature or humidity exceeds the limit, the water behavior exists in the set period (the water probability is high in the case of analyzing the water according to historical water data), the water behavior is compared with the obtained weather prediction data, whether the water behavior exists in the corresponding set period is judged according to the obtained weather prediction data, and therefore a water time sequence can be generated.
Preferably, the identifying whether the water supply temperature of the solar water heater at the target moment meets the requirement includes: acquiring a water temperature set by a user; comprehensively considering the influence of the climate environment, and determining the water supply temperature at the target moment; when the water supply temperature is higher than the water supply temperature, the water supply temperature is judged to meet the requirement.
The water temperature can be set according to a user, and can be automatically matched according to the water use of each set period, for example, the water temperature is 50 ℃ when the water is used for washing in the morning in winter, and the water temperature is 42 ℃ when the water is used for bathing in the evening in summer. It is understood that the winter and summer periods herein correspond to the temperature or humidity in the climate environment.
When the water supply temperature at the target time is determined to be higher than the water supply temperature (when the water supply temperature is higher than the water supply temperature (the water supply requirement can be met by mixing the water supply temperature with cold water), water supply can be performed at the target time. When the water supply temperature is less than the water supply temperature, the stored water in the solar water heater needs to be heated, either by solar energy or by electric energy. It is noted that the target time is determined in advance, and the stored water is affected by the climate environment during a period of time from the current time to the target time, and consideration is required for this effect.
Preferably, when the water supply temperature meets the water supply temperature requirement, the solar water heater stops heating the stored water and converts solar energy into electric energy for storage; wherein the stored electrical energy is capable of heating at least the stored water from a minimum temperature to a water temperature; the solar water heater can heat the stored water to the water temperature at the target moment, and the stored water is heated by the solar water heater; otherwise, the stored water is heated by electric energy or by a combination of solar water heater and electric energy.
The invention additionally provides a set of electric energy conversion and storage device for the solar water heater, when the storage water in the solar water heater can meet the use requirement at the target moment, the electric energy is timely stored by starting the electric energy conversion device and realizing the conversion from solar energy to electric energy. The stored electric energy can be used for heating and storing water, and can be used for emergency under the condition of insufficient sunlight illumination; the more electrical energy stored is theoretically better, but at least the need to ensure that the heating of the stored water to the water temperature at one time can be accomplished.

Detailed Description
The technical solutions of the present invention will be clearly and completely described in connection with the embodiments, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-2, an embodiment of a first aspect of the present invention provides a solar water heater control and regulation system, including a central control module, and a data acquisition module and a water supply control module connected with the central control module; the central control module collects historical water use data through the data acquisition module, performs division statistics on the historical water use data of each day according to a set period, and generates a water use time sequence by combining weather prediction data; the central control module determines the latest water use time according to the water use time sequence and marks the latest water use time as a target time; and controlling the solar water heater to heat the stored water; identifying whether the water supply temperature of the solar water heater at the target moment meets the requirement; the solar water heater stops heating the stored water and converts solar energy into electric energy for storage; and if not, heating the stored water by using the solar water heater or the stored electric energy.
The technical scheme of the invention is specifically illustrated below.
In this embodiment, it is first determined whether the historical water consumption data of the user is satisfactory, and a water consumption time series is generated, and the main approach is to compare the time span of the historical water consumption data with the time span of the water consumption time series. Assuming that the time span of the water use time sequence is one day, that is, when the solar water heater is controlled, knowing what time the user uses water in the future day; the preset multiple is thirty times, so that the historical water consumption data of the user needs to be covered for at least thirty days, and the continuous coverage is preferable; if the historical water consumption data of the user covers three months, judging that the historical water consumption data meets the requirements, and then generating a water consumption time sequence; if the historical water data is covered for twenty days, the historical water data is not satisfactory, and the historical water data needs to be supplemented at the moment.
In an alternative embodiment, when the historical water consumption data of the user meets the requirement, dividing the historical water consumption data of each day based on a set period to obtain a plurality of data segments; after the historical water consumption data are all divided, a water consumption climate threshold value corresponding to a set period is obtained based on the climate environment and a plurality of data segments, and a water consumption time sequence is obtained by combining weather prediction data.
The historical water consumption data are extracted according to the day, and the historical water consumption data of each day are divided according to a set period. If the set period is one hour, the period is divided into twenty-four time periods each day; if the set period is two hours, each day is divided into twelve time periods. When the time span of the historical water consumption data is thirty days, each set period corresponds to thirty data segments, and when the water consumption behaviors exist among users in the thirty data segments, the water consumption behaviors exist among users in the set period in the water consumption time sequence; the set period in the water usage time series is also set to have water usage behavior when the proportion of the user's water usage behavior present in the thirty data segments is greater than the water usage behavior absent. It should be noted that when the water usage behavior of the thirty data segments may be difficult to distinguish from the ratio, the analysis may be performed from the climate environment, such as that the water usage behavior of low temperature is large, and the water usage behavior of high temperature Wen Yongshui (where high temperature water and low temperature water refer to water supplied by a solar water heater) is small, and the boundary between high temperature and low temperature is the water usage climate threshold. In the water consumption time sequence, the weather prediction data and the water consumption weather threshold value are judged, and then the water consumption behavior is set for the corresponding set period.
In another preferred embodiment, historical water usage data needs to be supplemented. In this embodiment, the historical water use data is supplemented, and the time span can be supplemented from the aspect of time span, for example, if the time span of the historical water use data of the user is twenty days, the time span of the other ten days is supplemented (forward) by the historical water use data of other users; the system can also supplement the data quantity of the current day, extract the historical water consumption data of other users on a certain day, ensure the data quantity to be enough, and analyze the supplemented historical water consumption data to generate a water consumption time sequence.
When the historical water consumption sequence meeting the requirements is analyzed, each set period corresponds to a plurality of data segments, and when the water consumption behaviors exist in the data segments of a certain set period, the corresponding set period in the water consumption time sequence is set to be the water consumption behavior; when the water use behaviors do not exist in the data segments of a certain set period, the data segments are set according to the water use behavior existence proportion, and if the water use behaviors exist in the data segments of 9 sets, the corresponding set period in the water use time sequence is set to be the water use behavior. And when the proportion of the water consumption behavior of the data segments corresponding to a certain set period to the water consumption behavior of the data segments is close to that of the data segments not corresponding to the data segments, analyzing the influence of the climate environment on the water consumption behavior, namely determining a water consumption climate threshold value, and comparing the weather forecast data with the water consumption climate threshold value to set whether the water consumption behavior exists in the corresponding set period in the water consumption time sequence.
The water usage time series in this embodiment can be understood as a time period (set period) in which the water usage behavior of the user is predicted to exist in the future day based on the satisfactory historical water usage data. The target time can be determined by determining the water consumption time sequence, and then determining the water consumption behavior of the user in which set period. At the moment, the temperature of the stored water in the solar water heater is higher than the water temperature, and the stored water is converted into electric energy for storage under the condition of sufficient illumination intensity, and the solar water heater does not work under the condition of insufficient illumination intensity; when the temperature of the stored water in the solar water heater is less than or equal to the water temperature and the illumination intensity is sufficient, the stored water is heated by the solar water heater until the temperature meets the requirement, and under the condition of sufficient illumination intensity, the stored water is heated by electric energy. In other preferred embodiments, multiple successive target times may be determined simultaneously, and considerations may be consolidated when two target times are close.
The above embodiments are only for illustrating the technical method of the present invention and not for limiting the same, and it should be understood by those skilled in the art that the technical method of the present invention may be modified or substituted without departing from the spirit and scope of the technical method of the present invention.
