Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Thus, a feature indicated in this specification will serve to explain one of the features of one embodiment of the invention, and does not imply that every embodiment of the invention must have the stated feature. Further, it should be noted that this specification describes many features. Although some features may be combined to show a possible system design, these features may also be used in other combinations not explicitly described. Thus, the combinations illustrated are not intended to be limiting unless otherwise specified.
As shown in fig. 1, in the method for controlling a pipe heater according to the present invention, a temperature difference between rooms is obtained, and then the opening degree of a valve corresponding to each room is calculated according to the temperature difference.
The user can set an independent control instruction of each room, such as a target temperature of one room, on the mobile phone APP in advance, if the different heating of each room is needed, the real-time temperature of the room needs to be detected first, and then the real-time temperature is subtracted from the target temperature of the room, so that the temperature difference of the room can be obtained, for example, the target temperature set in the living room is 30 degrees, and the target temperature set in the kitchen and the dining room is 24 degrees. Then the temperature in each room is 10 degrees, the temperature difference in the living room is 20 degrees, and the temperature difference in the kitchen and the dining room is 14 degrees.
And opening the pipeline valve corresponding to the room with the maximum temperature difference to the maximum opening, and then calculating the openings of other rooms according to a formula Ai = Amax Ji/Jmax to realize the differential heating of each room. Wherein Ai is the opening of other rooms, Amax is the maximum opening, Ji is the temperature difference of other rooms, and Jmax is the maximum temperature difference. For example, assuming that the living room is the room with the largest temperature difference, the customer's line valve is opened to the maximum opening Amax, and the line valve of the kitchen is opened at archway = Amax 14/20.
In the above process, when the time required for each room to reach the target temperature is different, the longest time among the times required for each room to reach the target temperature is selected to calculate the time required for the user to issue the heating start instruction.
Although the pipeline heating equipment can be automatically started, the automatic starting at a given fixed time is not always suitable for the requirements of users, energy waste is easily caused, the young people are working or going to work at most of the day, and if the rooms needing heating are completely heated before returning home or arriving home, the heating is necessary. Therefore, on the basis of meeting the requirements of energy conservation and users, the pipeline heating equipment can prompt the users to start at a proper time point when the users need to start the pipeline heating equipment.
The time required for each room to reach the target temperature with the current temperature difference is obtained, and the time is an estimated value obtained in advance according to the user use data. And then, according to the time point of the user for going home and the acquired commuting time of the user, on the basis of the time point of the user for going home, the time point of the user for arriving home can be obtained by adding the commuting time of the user, and then the time required by each room for reaching the target temperature is subtracted from the time point of the user for arriving home, so that the time required by the user for sending a heating starting instruction can be calculated. And when the time that the user needs to send a heating starting instruction comes, reminding the user. In one embodiment, when the user does not return home or is on the way home, the user gives a time point of preparing to return home, the system evaluates the time of the daily commute to home, calculates the approximate time of the user to home, and reversely calculates the heating temperature rise which should be started before a certain time point by combining the time length required for heating the room. Before the time comes, the user is reminded in advance in an alarm-like mode to carry out heating control specified input on the house at home.
The existing map software is a very mature technology for calculating the traffic time between two known places on the basis of big data, and the estimation of the commute time can call third-party software. When the user is at a new place, the user-to-home time is confirmed by an actual specific traffic commuting mode, and in order to avoid the situation that the commuting time is not accurate enough, the method also provides a certain time margin for buffering, the estimated commuting time of the user is added with the time margin to obtain the final commuting time of the user, and the time for the user to send a heating starting instruction is calculated based on the final commuting time of the user, in a specific embodiment, the time margin can be 20% of the estimated commuting time, the final commuting time of the user is obtained through the time margin, the user-to-home time point is obtained through the final commuting time of the user, and the time point for starting heating a room is required.
In order to further save energy, the real-time temperature detection, temperature difference and opening calculation steps of each room are started when the time point set by the user to get home is reached.
The invention also provides a corresponding pipeline heating system, which comprises pipeline heating equipment, such as a wall-mounted furnace and the like, pipelines for transmitting the heating medium provided by the pipeline heating equipment to each room, and valves and valve controllers arranged on the pipelines of each room. The pipeline heating system also comprises a main control module, and the main control module adopts the control method of the pipeline heating equipment in the technical scheme to control.
As shown in fig. 2, in one embodiment, the main control module is disposed in the APP of the mobile terminal of the user. The user inputs independent control instructions for each room of the house through the App on the mobile terminal,
then the APP transmits corresponding control signals to a remote home through wireless communication technology such as network WiFi, and the control signals are received and processed by a central controller in the home. The processing is divided into two branches, wherein one branch is that the wall-mounted boiler can make corresponding action feedback such as heating work when receiving a signal sent by the central controller. The other way is that central controller divides the control signal of app output to corresponding room accurately, is controlled the aperture of pipeline valve by pipeline controller according to valve opening value, when hanging stove begins to heat, can realize long-range real-time difference heating control.
Each room can be displayed on the App interface, a user can name the room a, the room B and the like on the App, and when the user is near to work or on the way to work, the user can enter into setting the target temperature of the room by clicking the corresponding room icon. If the user does not input the target temperature of a certain room, the real-time temperature of the room is defaulted to be the target temperature, namely the temperature difference of the room is 0.
And opening the pipeline valve corresponding to the room with the maximum temperature difference to the maximum opening degree, wherein the opening degree range is 0-1, namely the minimum opening degree is 0, namely the pipeline valve is closed, the maximum opening degree is 1, and the pipeline valve is fully opened. And selecting the room with the maximum temperature difference as a reference, and calculating the corresponding percentage according to the opening degree of the pipeline valves of the rest rooms.
By installing a signal receiving processor in each room, the signal receiving processor is then connected to a central controller. The central controller processes the received control signal and makes a corresponding response to control the wall-mounted furnace and the like. For example, the wall-mounted boiler performs action feedback, works for heating or does not work according to the sum of the received temperature difference values. The pipeline controller receives and executes the opening value signal of the pipeline valve of the room, and the heating water prepared by the wall-mounted boiler is conveyed to the required room by virtue of the pipeline, so that differential heating is realized.
In other embodiments, the architecture of fig. 2 is not limited, for example, a general signal receiving processor may be used to receive the APP signals operated by the user, and then the general signal receiving processor may be distributed to the pipeline controllers, thereby eliminating the cost of the central processor, the cost of the signal receiving processor in each room, and so on.
The invention can remotely control the pipeline heating equipment, can independently set the target temperature of each room, has clear and intuitive target input index, realizes the difference function of different rooms, and can remind a user to start the pipeline heating equipment in advance at a proper time point.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
