Description
Technical Field
The application relates to the technical field of heating stove control, in particular to a heating stove control system and a heating stove control method.
Background
The operation control of an existing heating stove (for example, a gas wall-mounted stove) generally has two modes, one mode is a heating stove operation/stop control mode, and the other mode is a heating stove modulation control mode.
In the heating stove operation/stop control mode, the controller of each room can open/close the heating demand by opening/closing the valve of the circulation water pipe, and also close/open the dry contact connected to the heating stove. When all the room controllers close the heating demand and the corresponding dry contacts are all disconnected, a stop signal is generated at one side of the heating stove to stop the heating stove. If the heating demand of the controller of any one room is opened, i.e. the corresponding dry contact is closed, the heating stove will start to operate. Thus, the heating demand is satisfied by the operation/stop of the heating furnace. However, in this control scheme, the heating stove is always operated at a set power (usually the maximum power), resulting in a waste of energy (e.g., gas).
In the heating stove modulation control mode, the controller in each room can also adjust the heating demand in room alone through the valve of opening/closing circulating water pipe, and the heating stove controller can adjust the play water temperature of heating stove according to control logic and algorithm to the modulation of heating stove to energy can be saved when satisfying the heating demand. However, in this control method, the furnace controller and the room controller operate separately, so that the furnace controller cannot accurately determine from which room the real heating demand comes and quantify the heating demand. In addition, when each room has reached the desired temperature and all valves have been closed, the heating stove does not stop running, but remains heated, which is likely to result in the risk of excessive temperatures and possible failure of the heating stove, not to mention significant waste of energy.
Accordingly, there is a need for an improved heating stove control system and heating stove control method that can accurately analyze the heating demand of a single room, intelligently provide higher comfort, and save energy and extend the life of the device.

Detailed Description
Preferred embodiments of the present application are described in detail below with reference to examples. In the embodiments of the present application, the present application will be described by taking a control system of a gas wall-hanging stove as an example. However, it should be understood by those skilled in the art that these exemplary embodiments are not meant to limit the present application in any way. The heating stove control system and the heating stove control method of the application can also be applied to other forms of heating stoves, such as electric energy heating stoves and the like.
Features in the embodiments of the present application may be combined with each other without conflict. In the drawings, other components or steps have been omitted for the sake of brevity, but this does not indicate that the heating stove control system of the present application cannot include other components nor that the heating stove control method of the present application cannot include other steps. It should be understood that the sizes, proportions, and numbers of parts or steps in the drawings are not intended to limit the present application.
Fig. 1 schematically illustrates a schematic diagram of a heating system formed by a heating stove control system according to an embodiment of the present application and a heating stove and associated accessories, which is generally a commonly employed residential heating system. As shown in fig. 1, the heating stove control system of the present application is communicatively connected to a heating stove 10, for example, by a wired connection such as OT communication protocol or a wireless connection such as WiFi, ZigBee, bluetooth, 868MHz RF. The heating stove 10 may be, for example, a gas wall-hanging stove, which includes a gas supply line, a combustion device, a water circulation line, a pump, a fan, a sensor, a control device, and the like. Of course, the heating stove 10 may also employ other energy sources and may include different components, which will not be described in detail herein.
The heating stove 10 is provided with a water outlet port communicated with the water outlet pipeline 11 and a water return port communicated with the water return pipeline 12, the water outlet pipeline 11 and the water return pipeline 12 are communicated with the valve assembly 70, and are communicated with heating equipment through the valve assembly 70 to form a circulation loop. The heating device may be a heat sink 50 or a floor heating system 60. The valve assembly 70 is configured to close and open a circulation line connected between the heating stove 10 and the heating equipment, and may include a plurality of valves, each of which controls a line leading to the heating equipment in a corresponding room.
The heating stove control system of the present application includes a main controller 20, at least one sub-controller 30, 40 and a valve controller 80. The master controller 20 is configured to be able to modulate the operation of the heating stove 10 according to a temperature control Protocol (e.g., Open heating Protocol), and is typically installed in a living room or a living room. In fig. 1, two sub-controllers 30, 40 are shown, which are configured to sense the actual temperature of the surrounding environment and to receive a set temperature of a user. Of course, more sub-controllers may be provided. In particular, typically, one secondary controller may be installed per room, for example, in a bedroom. It should be noted that in the embodiments of the present application, the sub-controller does not directly control the opening and closing of the valve, but senses the actual temperature in the corresponding room and receives the set temperature of the user. The valve controller 80 is configured to close and open the valves in the valve assembly 70. In an embodiment of the present application, the main controller 20 is communicatively connected with the at least one sub-controller 30, 40 and the valve controller 80, and sends instructions to the valve controller 80 to open and close the valves in the valve assembly 70 according to the actual and set temperatures periodically received from the at least one sub-controller 30, 40. In this way, the valve controller 80 can open and close the valves of the pipes leading to the respective rooms. As described above and schematically shown in fig. 1, the connections between the main controller 20, the sub-controllers 30, 40 and the valve controller 80 may be wired connections or wireless connections.
As shown in fig. 2, the main controller 20 may periodically obtain temperature information from the sub-controllers 30, 40 through lines L30, L40, judge a heating demand of each room according to control logic, and then may transmit a command to the valve controller 80 through a line C80 so that the valve controller 80 may directly close and open valves corresponding to the sub-controllers 30, 40. Specifically, when the actual temperature of a room reaches a certain threshold value at or above the set temperature, the main controller 20 may determine that the heating demand of the room is off, and then may send an instruction to close the valve to the valve controller 80, whereas when the actual temperature of a room is below the set temperature or below a certain threshold value below the set temperature, the main controller 20 may send an instruction to open the valve to the valve controller 80. Therefore, the heating stove control system of this application can judge accurately which room has the heating demand to close and open the valve correspondingly. Because the sub-controllers do not directly control the closing and opening of the corresponding valves, but are controlled by the valve controllers in a centralized manner, control lines from each sub-controller to the corresponding valves are not needed, and the arrangement and maintenance cost of the lines can be saved.
In addition, the main controller 20 may modulate the operation of the heating furnace 10 through the line L10 according to the judged heating demand from the sub-controllers 30 and 40 (corresponding to each room), for example, adjust the set outlet water temperature of the heating furnace 10. According to different heating requirements, the heating stove 10 can be modulated to different set outlet water temperatures on the basis of the set outlet water temperature default, and according to different heating devices, the set outlet water temperature default of the heating stove can be different, for example, when the heating device is the heat sink 50, the set outlet water temperature default can be set to 50 degrees, and when the heating device is the floor heating system 60, the set outlet water temperature default can be set to 60 degrees. The modulation of the set outlet water temperature will be described in further detail in the following paragraphs.
Note that the lines L10, L30, L40, and C80 shown in fig. 2 may be either wired lines or wireless lines. The information transfer between the main controller 20 and the sub-controllers 30, 40 may be a polling process, i.e., the main controller 20 sends inquiry information about the actual room temperature and the set room temperature to the sub-controllers 30, 40 at a set period, and the sub-controllers 30, 40 return response information with the actual room temperature and the set room temperature. Each cycle may be 1 minute, 2 minutes, or other settable value.
According to an embodiment of the present application, in each cycle, when the heating demand from each of the at least one sub-controller 30, 40 is turned off, the main controller 20 does not immediately issue a command to turn off the heating stove 10, but calculates and modulates the set outlet water temperature of the heating stove 10 such that the set outlet water temperature is modulated to a temperature less than the current outlet water temperature of the heating stove 10. Thus, the temperature of the room is prevented from rapidly dropping, the heating stove 10 is prevented from being frequently started, and energy is saved. The heating stove 10 may be modulated in two modes, for example, a comfort mode and an economy mode, although there may be more modes and may be set by the user. In the comfort mode, the set leaving water temperature Tset may be modulated to a temperature that is 2 degrees less than the current leaving water temperature Tw of the heating stove 10, i.e., Tset ═ Tw-2, and in the economy mode, the set leaving water temperature Tset may be modulated to a temperature that is 4 degrees less than the current leaving water temperature Tw of the heating stove 10, i.e., Tset ═ Tw-4. After a certain number of modulation cycles, the main controller 20 sends an instruction to stop the heating stove 10 if the heating demand from each of the at least one sub-controller 30, 40 is still off. In this way, the set leaving water temperature Tset of the heating stove 10 can be slowly lowered in an oscillating manner within a very small range, thereby avoiding frequent start-up of the heating stove 10 and saving energy.
According to another embodiment of the present application, in each cycle, when a heating demand from any one of the at least one sub-controller 30, 40 is turned on, the main controller 20 calculates and modulates the set outlet water temperature Tset of the heating stove 10 such that the set outlet water temperature Tset is modulated to a temperature higher than the set outlet water temperature default value Tdef of the heating stove 10. In this way, heating can be performed more quickly. The set leaving water temperature Tset may be modulated as the sum of a set leaving water temperature default value Tdef of the heating stove 10 and an increased temperature Δ T, which may be a fixed value or a different value depending on the modulation mode. For example, the increase temperature Δ T may be selected from a difference between an actual temperature and a set temperature of at least one sub-controller 30, 40. For example, assuming that there are 3 rooms each having 1 sub-controller installed, the main controller 20 may obtain differences Δ T1, Δ T2, Δ T3 (positive values) between actual temperatures and set temperatures of the 3 rooms and heating demands D1, D2, D3 (expressed by ON/OFF) of the 3 rooms, and in the comfort mode, the set leaving water temperature Tset may be modulated as a sum of a current set leaving water temperature default Tdef of the heating stove 10 and a maximum difference Max (Δ T1, Δ T2, Δ T3) among the above three differences, and in the economy mode, the set leaving water temperature Tset may be modulated as a sum of a current set leaving water temperature default Tdef of the heating stove 10 and a minimum difference Min (Δ T1, Δ T2, Δ T3) among the above three differences.
The above discusses how to modulate the set leaving water temperature Tset of the heating stove 10 when the heating demand is completely closed and at least one heating demand exists. The calculation method of the set outlet water temperature Tset corresponding to various heating demands during the modulation process is listed in the following table 1.
TABLE 1
Wherein D1, D2 and D3 respectively represent the heating demands of three rooms, ON represents that the heating demand is ON, namely the room needs to supply heat, OFF represents that the heating demand is OFF, namely the room needs to stop supplying heat; Δ T1, Δ T2, and Δ T3 represent differences between actual temperatures and set temperatures of the three rooms, respectively, and are positive values; tw is the current leaving water temperature of the heating stove; tdef is a set outlet water temperature default value of the heating stove; tset is the set leaving water temperature of the heating stove Tset. As can be seen from table 1, in each cycle, when all heating demands are turned off, the main controller calculates the set leaving water temperature Tset of the heating stove 10 to be a temperature less than the current leaving water temperature Tw of the heating stove 10 and modulates it accordingly; and in each cycle, when there is at least one heating demand, the main controller 20 calculates the set outlet water temperature Tset of the heating stove 10 to a temperature higher than the set outlet water temperature default Tdef of the heating stove 10. Of course, the set outlet water temperature Tset after modulation may have different specific values according to different modulation modes, such as a comfort mode and an economy mode, as described above.
In order to avoid that the set outlet water temperature Tset of the heating stove 10 exceeds the operating temperature range of the heating stove 10, in each period, when the calculated set outlet water temperature Tset is out of the range from the lowest outlet water temperature to the highest outlet water temperature of the heating stove 10, the main controller 20 modulates the set outlet water temperature Tset to the corresponding lowest outlet water temperature or highest outlet water temperature. For example, in the case where the operating temperature range of the heating stove is 45 to 80 ℃, when the calculated set outlet water temperature Tset is less than or equal to 45 ℃, the main controller 20 modulates the set outlet water temperature Tset to 45 ℃, and when the calculated set outlet water temperature Tset is greater than or equal to 80 ℃, the main controller 20 modulates the set outlet water temperature Tset to 80 ℃.
To verify the above modulation process, simulations were performed using a heating stove control system comprising a master controller and two slave controllers, the simulation results being shown in fig. 3. As shown in fig. 3, in each cycle, the set leaving water temperature Tset of the heating stove 10 is calculated in the calculation manner as listed in the foregoing table 1 as a function of the current leaving water temperature Tw of the heating stove 10, the actual temperature T1 in the first room, and the actual temperature T2 in the second room, and thus the heating stove is modulated.
In the foregoing, it is mentioned that the determination of the heating demand of one room is based on the comparison result of the actual temperature sensed by the corresponding sub-controller and the set temperature input by the user. Generally, when the actual temperature is greater than or equal to the set temperature, the heating demand is considered to be off, and when the actual temperature is lower than the set temperature, the heating demand is considered to be on. However, in order to avoid too frequent changes in the heating demand, a threshold value x is often set. For example, the heating demand is considered to be off when the actual temperature from one sub-controller is greater than the set temperature by a threshold x, and the heating demand is considered to be on when the actual temperature from one sub-controller is less than the set temperature by the threshold x.
In order to more accurately judge the heating demand for further energy saving, the heating stove control system of the present application further includes at least one motion sensor 31, 41 provided corresponding to the at least one sub-controller 30, 40 for sensing whether there is motion in the surrounding environment, and the main controller 20 may be further configured to judge the heating demand from the at least one sub-controller 30, 40 according to the sensed data from the at least one motion sensor 31, 41. Referring to fig. 4, R0 denotes an unattended room, R1 denotes a manned room, HD denotes a heating demand, T denotes an actual temperature of the room, Td denotes a set temperature of the room, x denotes a threshold, and T denotes time. When the sensed data of one motion sensor 31 indicates that there is motion, i.e., that a person is using the corresponding room (the case indicated by R1), the main controller 20 judges the heating demand from the sub-controller 30 as off when the actual temperature T from the corresponding one of the sub-controllers 30 is greater than the set temperature Td by a threshold value x. On the contrary, when the sensed data of one motion sensor 41 indicates that there is no motion, i.e., it indicates that no one uses the corresponding room (the case indicated by R0), the main controller 20 immediately judges the heating demand from the sub-controller 40 as off when the actual temperature T from the corresponding one of the sub-controllers 40 is greater than or equal to the set temperature Td.
It should be noted that although the main controller 20, the sub-controllers 30, 40 and the valve controller 80 are separate components in fig. 1, the main controller 20 may be integrated with one sub-controller, for example, when the main controller 20 is installed in a living room, it may be integrated with a sub-controller that should be installed in the living room. In addition, the motion sensors 31, 41 are shown on the respective sub-controllers 30, 40 in fig. 1, however the motion sensors 31, 41 may also be separate components.
The composition and operation of the heating stove control system of the present application, and the heating system formed with the heating stove and associated accessories, are described above with reference to fig. 1-4, and the heating stove control method of the present application is described below with reference to fig. 5.
As previously mentioned, the heating stove is communicatively connected with the heating stove control system of the present application. In step S1, the heating system is started and then enters a process of periodically modulating. At step S2, the actual temperature and the set temperature from the at least one sub-controller 30, 40 are received by the main controller 20 of the heating stove control system, and an instruction to open and close the valve in the valve assembly 70 between the heating stove 10 and the heating apparatus is sent to the valve controller 80. By receiving the actual temperature and the set temperature, the main controller 20 can judge the heating demand from at least one sub-controller 30, 40 and modulate the operation of the heating stove 10.
If the heating demand from each of the at least one sub-controller 30, 40 is turned off, step S3 is performed to determine whether the modulation mode is the comfort mode or the eco mode, and then step S4, i.e., the eco mode, is performed according to the determination result, the main controller 20 calculates the set outlet water temperature Tset of the heating stove 10 to a temperature 4 degrees lower than the current outlet water temperature Tw of the heating stove 10, or step S5, i.e., the comfort mode, the main controller 20 calculates the set outlet water temperature Tset of the heating stove 10 to a temperature 2 degrees lower than the current outlet water temperature Tw of the heating stove 10.
If the heating demand from any one of the at least one sub-controller 30, 40 is turned on, step S6 is performed, a difference between the actual temperature and the set temperature from the at least one sub-controller 30, 40 is calculated, then, step S4 is performed, it is determined whether the modulation mode is the comfort mode or the eco mode, and then step S8 is performed according to the determination result, i.e., the economy mode, the main controller 20 calculates the set leaving water temperature Tset of the heating stove 10 as the sum of the set leaving water temperature default value Tdef of the heating stove 10 and the minimum difference value among the difference values of the actual temperature and the set temperature of the at least one sub-controller 30, 40, or performs step S9, i.e., the comfort mode, the main controller 20 calculates the set leaving water temperature Tset of the heating stove 10 as the sum of the set leaving water temperature default value Tdef of the heating stove 10 and the maximum difference among the differences of the actual temperature and the set temperature of the at least one sub-controller 30, 40.
After the set leaving water temperature Tset of the heating stove is calculated, performing step S10, determining whether the calculated set leaving water temperature Tset is greater than or equal to the maximum operating temperature of the heating stove, and if so, performing step S11, determining the set leaving water temperature Tset of the heating stove as the maximum operating temperature of the heating stove, and performing step S14; otherwise, if the temperature is less than the preset temperature, step S12 is executed, whether the calculated set outlet water temperature Tset is less than or equal to the minimum operating temperature of the heating stove is judged, if so, step S13 is executed, the set outlet water temperature Tset of the heating stove is determined as the minimum operating temperature of the heating stove, otherwise, step S14 is executed if it is greater.
In step S14, the main controller modulates the heating stove according to the determined set outlet water temperature Tset of the heating stove, and then delays for a certain time, for example, 1 minute, and returns to step S2 to start modulation of the next cycle.
After a certain number of modulation cycles, the main controller 20 sends an instruction to stop the heating stove 10 if the heating demand from each of the at least one sub-controller 30, 40 is still off.
In the heating stove control method described above, when only one modulation mode is employed, the step of determining the modulation mode may be omitted.
The utility model provides a heating stove control system and heating stove control method, the heating demand in every room can be analyzed accurately through main control unit and sub-controller to come closing and opening of control flap through main control unit, can according to the judged result intelligently, automatically modulate the operation of heating stove, alleviate the fluctuation of outlet water temperature and room temperature, thereby can provide higher comfort level, improve the efficiency of heating stove, reduce energy consumption, prolong equipment life and save expense.

For example, the present application is described in the preferred embodiment with respect to a heating stove control system for a gas wall-hanging stove, but may find application in other forms of heating stoves that use other sources of energy (e.g., electricity).
The embodiments described above and shown in the drawings are to be understood as illustrative and not restrictive of the application. It will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit of the application, and these changes and modifications do not depart from the scope of the application.
