[0002] With the rapid economic development and the improvement of people's living standards, the centralized heating technology has gradually started to develop rapidly. Especially for residential communities in the northern regions, the demand for centralized heating is particularly prominent.

[0003] Currently, centralized heating mainly heats the circulating water by burning energy, and then makes the heated circulating water flow through the heating equipment in the room. The heating equipment transfers the heat of the circulating water to the air in the room, thereby heating the indoor temperature.

[0004] However, since it is difficult for heat suppliers to count the heating demands of all users, heat energy is wasted. Summary of the Invention

[0017] By adopting the above technical solution, setting the indoor temperature curve according to the working state, off-duty state, and rest state is convenient for users to set the indoor temperature in the work-leisure state, so as to achieve the purpose of reasonably planning heat energy and effectively saving heat energy, which is economical and affordable for users.

[0022] By adopting the above technical solution, for users who initially set the indoor temperature curve, they can refer to the indoor reference temperature curves of users in the same or similar work-leisure states.

[0067] The present application discloses an intelligent control system for household heating. Referring to Figure 1 , it includes a user equipment 1, a background control equipment 2, and a flow control valve 3.

[0068] The user equipment 1 is used to acquire the indoor historical temperature curve and the indoor reference temperature curve, form an indoor temperature curve according to the indoor historical temperature curve and the indoor reference temperature curve, and send the indoor temperature curve to the background control equipment 2. Multiple user equipments 1 can be set, and they can be portable electronic devices such as mobile phones, tablet computers, multimedia playback devices, PDAs (Personal Digital Assistants).

[0069] The background control device 2 forms a user temperature set curve from the indoor temperature curves of multiple users, and combines it with the outdoor air temperature change curve to form a heating temperature curve, so as to facilitate the heating provider to accurately understand the heating demand of users. A main control valve is connected to one side of the background control device 2. A plurality of flow control valves 3 are provided, and each flow control valve 3 is installed on the side of the user. The main control valve is connected to the plurality of flow control valves 3. For the connection manners between the background control device 2, the main control valve, the plurality of flow control valves 3 and the plurality of intermediate control valves, those skilled in the art can easily think of the wired connection manner or the wireless connection manner. The specific connection and communication manners are not specifically described and limited in this embodiment. The background control device 2 adjusts the opening degree of the main control valve according to the heating temperature curve, and adjusts the opening degree of the flow control valve 3 according to the indoor temperature curve, so as to change the flow rate of the circulating water, and further change the temperature in the room where the user lives.

[0070] Referring to Figure 1 and Figure 2 , the user device 1 includes an acquisition unit 11, a processing unit 12 and a sending unit 13. Among them, the acquisition unit 11 is used to acquire the indoor historical temperature curve and the indoor reference temperature curve. The processing unit 12 is used to set the indoor temperature curve according to the indoor historical temperature curve and the indoor reference temperature curve. The sending unit 13 is used to send the indoor temperature curve to the background control device 2.

[0071] Specifically, in the initial state, all indoor temperature curves are formed after being set by the users themselves. The indoor temperature curves set by multiple users form an indoor reference temperature curve. In this embodiment, how to obtain the user temperature curve is not limited. For the initial user, since the initial user does not have an indoor historical temperature curve, the indoor reference temperature curve can be directly referred to. For the user who has set the indoor temperature curve, the historical temperature curve and the reference temperature curve are stored in the background control device 2. The user can call the indoor historical temperature curve and the reference temperature curve through the user device 1. Therefore, the indoor historical temperature curve and the reference temperature curve can be used as references at the same time to set their own indoor temperature curve, so as to improve the user experience.

[0072] Specifically, the multiple users mentioned here are users with the same or similar work-leisure status, and the users with the same or similar work-leisure status are referenced by the current user. If the working hours of the current user are from 9:00 to 17:00 and the off-duty hours are from 17:00 to 9:00 the next day, and the working hours of other users are from 8:00 to 16:00 and the off-duty hours are from 16:00 to 8:00 the next day, then the two types of users are users with similar work-leisure status. Another example, if the working hours of the current user are from 9:00 to 17:00 and the off-duty hours are from 17:00 to 9:00 the next day, and the working hours of other users are from 9:00 to 17:30 and the off-duty hours are from 17:30 to 9:00 the next day, then the two types of users are also users with similar work-leisure status. If the working hours of the current user are from 9:00 to 17:00 and the off-duty hours are from 17:00 to 9:00 the next day, and the working hours of other users are from 13:00 to 21:30 and the off-duty hours are from 21:30 to 13:00 the next day, then the two are users with different work-leisure status.

[0073] Reference Figure 3 And Figure 4 , the indoor historical temperature curve is the temperature curve in the user's work-idle state. Similarly, the indoor reference curve is also the temperature curve in the user's work-idle state. Specifically, the user's work-idle state includes the states of going to work, getting off work, and resting.

[0074] The time of the working state pointed out in the embodiments of the present application can be from 8:00 to 17:30 on a legal working day, or from 9:00 to 17:00, or from 13:00 to 1:00 the next day, and can be set according to the user's working hours. The time of the off-duty state can be the non-working time on a legal working day and can be set according to the user's non-working time, which will not be elaborated here. The time of the resting state can be the time of a legal holiday, or the user's own vacation time or leave time.

[0075] Specifically, when the user's working hours are from 9:00 to 17:00 and the off-duty hours are from 17:00 to 9:00 the next day, since the user may not be in the living room from 9:00 to 17:00, the position of the indoor temperature curve can be adjusted to a relatively low position. When the user is off work and is active indoors, the position of the indoor temperature curve can be adjusted to a relatively high position. When the user is off work and is in the sleeping state, the position of the user's indoor curve can be adjusted to a relatively middle position, and the user can adjust the position of the indoor temperature curve according to his own situation according to his own needs.

[0076] Among them, the period of the indoor temperature curve is at least: one day, one week, or one month. Taking the period of the indoor temperature curve as one day as an example, for the indoor temperature curve within one day, the user can set the hour as the setting unit, and after setting 24 setting units, an indoor temperature curve is formed. Of course, it is also possible to set 3 hours as the setting unit and form an indoor temperature curve after setting 8 setting units. In the embodiments of the present application, this period is not limited.

[0077] Referring to Figure 1 and Figure 5 , the background control device 2 includes an indoor temperature acquisition module 21, an outdoor temperature acquisition module 22, and a temperature data processing module 23.

[0078] The indoor temperature acquisition module 21 acquires the indoor temperature set curve. Among them, the indoor temperature set curve integrates the indoor temperature curves of multiple users, and the indoor temperature curve is the temperature curve in the user's work-idle state.

[0079] Among them, the user device 1 acquires the indoor temperature curves of multiple users, fuses the indoor temperature curves of multiple users into an indoor temperature set curve, and sends the indoor temperature set curve to the background control device 2.

[0080] Among them, one user corresponds to one indoor temperature curve, and the temperature data processing module 23 assigns different weights to the indoor temperature curves of each user and fuses the indoor temperature curves of multiple users according to the weighted average method to form an indoor temperature set curve.

[0081] For example, within a certain period of time, the indoor temperature set value of user A is 20 °C, the indoor temperature set value of user B is 19.5 °C, the indoor temperature set value of user C is 15 °C, and the indoor temperature set value of user D is 14 °C. The background control device 2 assigns 8% weight to user A, the background control device 2 assigns 8% weight to user B, the background control device 2 assigns 5% weight to user C, and the background control device 2 assigns 4% weight to user D. Thus, the position of the indoor temperature set curve is closer to the indoor temperature curve with a higher weight, so that the heating requirements of users with higher and lower indoor temperatures can be met.

[0082] Or for example: C1X + C2Y + …… + CnZ = 1, C1 + C2 + …… + Cn = 1, where X, Y …… Z are the indoor temperature curves of each user, and C1, C2 …… Cn are the weights assigned to the indoor temperature curves of each user.

[0083] Outdoor temperature acquisition module 22 acquires the outdoor air temperature change curve, which is the outdoor air temperature change curve. The period of the outdoor air temperature change curve is consistent with that of the indoor temperature set curve, which can be one day, one week or one month. Specifically, the outdoor temperature acquisition module 22 directly acquires the outdoor air temperature change curve formed in the meteorological station and sends the outdoor temperature change curve to the temperature data processing module 23.

[0084] The temperature data processing module 23 constructs a heating temperature curve based on the indoor temperature set curve and the outdoor air temperature change curve, so that the background control device 2 can provide heat energy for users according to the heating temperature curve. Among them, the heating temperature curve satisfies the formula: FM(T)=(1 + K)*FN(T); where K is the heat loss coefficient, which is determined by the user's outdoor temperature change curve, and FN(T) is the indoor temperature set curve.

[0085] Specifically, in the initial state, all indoor historical temperature curves are formed by the users' self-settings; the user temperature curves set by multiple users form an indoor reference temperature curve; the indoor historical temperature curve is the temperature curve in the user's working-idle state, and the user's working-idle state includes the states of going to work, getting off work and resting. In particular, the indoor reference temperature curve is formed by fusing the user temperature curves of multiple users with the same or similar working-leisure time states.

[0086] Refer to Figure 1 and Figure 6 The household heating intelligent control system further includes a flow control valve 3, which includes a receiving unit 31 and an execution unit 32. Among them, the receiving unit 31 is used to receive the indoor temperature curve sent by the background control device 2; the execution unit 32 adjusts the opening degree of the flow control valve 3 according to the indoor temperature curve and the corresponding relationship; where the corresponding relationship includes the corresponding relationship between the size of the circulating water flow and the temperature, and a circulating water flow range corresponds to a temperature range.

[0087] Among them, the flow control valve 3 stores the indoor temperature curve after the preset adjustment time, and the indoor temperature curve after the preset adjustment time refers to shifting the indoor temperature curve to the left by the preset adjustment time on the time axis. Specifically, the indoor temperature curve after the preset adjustment time satisfies the function: Fa(T)=F(T - t), where t is the preset adjustment time value.

[0088] Before circulating water is introduced into the user's room, the background control device 2 adjusts the opening degree of the flow control valve 3 before the preset adjustment time according to the corresponding relationship, so as to facilitate the room temperature to reach the corresponding temperature on the indoor temperature curve within the preset adjustment time, further improving the user experience.

[0089] In a possible implementation, the household heating intelligent control system further includes an intermediate control valve, and the intermediate control valve includes one or more of a building control valve, a community control valve, and a neighborhood control valve. Among them, the background controller controls the opening degree of the main control valve according to the heat temperature curve.

[0090] The building control valve is arranged at the building and is used to control the opening degree of the building control valve according to the building temperature curve. The building control valve, the community control valve, and the neighborhood control valve all include a receiving unit 31 and an executing unit 32. Among them, the receiving unit 31 is used to receive the indoor temperature set curve sent by the background control device 2. The executing unit 32 adjusts the opening degree of the intermediate control valve according to the indoor temperature set curve and the corresponding relationship. Among them, the corresponding relationship includes the corresponding relationship between the size of the circulating water flow and the temperature, and a temperature range corresponds to a circulating water flow range.

[0091] For example, the background control device 2 forms a community temperature set curve according to multiple indoor temperature set curves and the outdoor air temperature change curve in the community, and adjusts the opening degree of the community control valve according to the community temperature set curve. The adjustment principles of the building control valve and the neighborhood control valve are similar to that of the community control valve and will not be elaborated here.

[0092] Particularly, when the flow control valve 3 corresponding to user A fails, the maintenance personnel can close the building control valve A corresponding to user A, so as to facilitate the maintenance of the flow control valve 3. Similarly, when the building control valve A fails, the maintenance personnel can close the community control valve A corresponding to the building control valve A, so as to facilitate the maintenance of the building control valve A. Similarly, when the community control valve A fails, the maintenance personnel can close the neighborhood control valve A corresponding to the community, so as to facilitate the maintenance of the community control valve A. Of course, without affecting other users, if the flow control valve 3 corresponding to user A fails, the maintenance personnel can also directly close any one or more of the building control valve, the community control valve, and the neighborhood control valve corresponding to user A, so as to facilitate the maintenance of the flow control valve 3.

[0093] In another possible implementation, if the flow control valves 3 of multiple users in the same community fail, without affecting other users, the maintenance personnel can close any one or more of the building control valve, the community control valve, and the neighborhood control valve according to the actual situation.

[0094] In still another possible implementation, if the community control valves of multiple community units all have problems, without affecting other users, the maintenance personnel can close any one or more of the neighborhood control valve or the main control valve according to the actual situation. In the above implementation, any solution that can achieve the maintenance of the control valve should be within the protection scope of this solution.

[0095] The embodiment of the present application also discloses a household heating intelligent control method, which is applied to the household heating intelligent control system as described above. The household heating intelligent control method includes steps S410 - S430:

[0096] S410. Obtain the indoor temperature set curve, where the indoor temperature set curve is formed by fusing the indoor temperature curves of multiple users, and the indoor temperature curve is the temperature curve in the user's work - leisure state.

[0097] In a possible implementation manner, the work - leisure state of the user includes the working state, the off - work state, and the rest state.

[0098] In a possible implementation manner, the indoor temperature set curve is formed by fusing the indoor temperature curves of multiple users, specifically including: one user corresponds to one indoor temperature curve. Among them, the background control device 2 assigns different weights to the indoor temperature curves of each user, and fuses the indoor temperature curves of multiple users into an indoor temperature set curve according to the weighted average method; where one indoor temperature curve of a user corresponds to one weight, and among multiple indoor temperature curves, the indoor temperature curve with a higher peak has a larger weight.

[0111] In a possible implementation, the household heating intelligent control system further includes a flow control valve 3, and the household heating intelligent control method further includes:

[0112] The flow control valve 3 receives the indoor temperature curve sent by the background control device 2.

[0113] The flow control valve 3 adjusts the opening degree of the flow control valve 3 according to the indoor temperature curve and the corresponding relationship; where the corresponding relationship includes the corresponding relationship between the size of the circulating water flow and the temperature, and a circulating water flow range corresponds to a temperature range.

[0114] In a possible implementation, the household heating intelligent control system further includes an intermediate control valve; the household heating intelligent control method further includes:

[0115] The intermediate control valve is arranged between the flow control valve 3 and the main control valve. The intermediate control valve includes one or more of a building control valve, a community control valve, and a neighborhood control valve. Among them, the background controller controls the opening degree of the main control valve according to the heat temperature curve.

[0116] The building control valve is arranged at the building and is used to control the opening degree of the building control valve according to the building temperature curve.

[0117] In a possible implementation, the flow control valve 3 stores the indoor temperature curve after a preset adjustment time.
