Description

Technical Field

[0001] The invention relates to the technical field of data processing, and in particular to a temperature automatic control method for an indoor heating system. Background Art

[0002] Indoor heating systems are an important part of various buildings, especially in cold seasons, which provide the necessary warmth and comfort for living and working environments. Traditional heating systems usually consist of a central heat source and a distribution network. The heat generated by the heat source is transferred to each room through a medium to maintain the indoor temperature within a suitable range. Automatic temperature control is achieved through integrated sensors, controllers and actuators. The temperature sensor is responsible for monitoring the indoor temperature. The controller calculates the required heat adjustment based on the deviation between the preset temperature set point and the actual temperature. The actuator adjusts the heat supply according to the controller's instructions to achieve the purpose of automatically adjusting the indoor temperature.

[0003] In some scenarios, the heating system generally regulates the indoor temperature at a constant heating rate. However, if the outside temperature drops, the building will react slowly to the temperature change due to the thermal inertia of the building construction, and the indoor temperature will not be affected immediately. However, if the heating system is only adjusted according to the indoor temperature, it may not increase heating for a period of time after the outside temperature drops, resulting in a lag in the indoor temperature regulation and a lower comfort level in the living environment.

[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the temperature automatic control method of an indoor heating system proposed by the present invention, its specific implementation method, structure, features and effects, in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0022] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0023] The specific scheme of the automatic temperature control method of an indoor heating system provided by the present invention is described in detail below with reference to the accompanying drawings.

[0024] It should be emphasized in advance that the embodiments of the present invention are mainly aimed at indoor heating scenarios. In order to facilitate overall logical analysis, all indoor temperatures and outdoor temperatures in the embodiments of the present invention are values ​​greater than 0. If there is a situation where the temperature is less than or equal to 0, all data can be linearly mapped and mapped to a preset positive value domain range, such as (0,100].

[0025] Embodiment 1:

[0026] See also Figure 1 , which shows a flow chart of a temperature automatic control method for an indoor heating system provided by an embodiment of the present invention, comprising:

[0027] Step S101, determining the initial time when the outdoor temperature of the target room starts to drop.

[0028] Specifically, the target room is equipped with an indoor heating system, which is used to heat the target room. The indoor heating system transports the central heat source to the target room through a pipeline. The indoor heating system includes a temperature controller, which is responsible for adjusting the heating rate of the indoor heating system of the room, thereby ensuring the stability of the temperature in the target room. The initial moment can be determined in the following way: when the outdoor temperature in two adjacent time periods is lower than the outdoor temperature in the previous time period, the start time of the latter time period is the initial moment. Or when the outdoor temperature continues to drop from a certain moment, the certain moment can be used as the initial moment.

[0029] Step S103, obtaining the indoor temperature, outdoor temperature and construction parameters of the target room at multiple moments after the initial moment.

[0030] Specifically, temperature collection devices can be installed indoors and outdoors of the target room respectively. The temperature collection devices include but are not limited to temperature sensors, thermometers, etc. The indoor temperature and outdoor temperature of the target room at different times are collected by the temperature collection devices. The collection interval can be set to 0.2 seconds.

[0031] Furthermore, the construction parameters include but are not limited to the average thickness of the walls of the room, the area of ​​the wall actually in contact with the outside world, the overall surface area of ​​the wall, etc.

[0032] Step S105, calculating the heat dissipation rate of the target room at multiple moments after the initial moment according to the indoor temperature, the outdoor temperature and the construction parameters.

[0033] Specifically, when the outdoor temperature begins to drop, the thermal inertia of the building will cause the indoor temperature to lag behind the outdoor temperature, and the corresponding indoor temperature will not have an obvious downward trend. Therefore, the indoor temperature needs to be adjusted in advance. Based on the changing characteristics of the indoor and outdoor temperature data, it is impossible to determine the time when advance adjustment is required. At this time, the heat dissipation rate of the room represents the real-time response ability of the room's heat to the outside temperature. The time when advance adjustment is required can be determined based on the heat dissipation rate.

[0034] Furthermore, general house heat dissipation is divided into conductive heat loss and convective heat loss. After the indoor heating system is turned on, the house is closed, so the corresponding heat loss can be ignored compared to the conductive heat loss. The conductive heat loss is mainly dissipated by walls, windows and ceilings. The corresponding heat dissipation rate is related to the construction parameters of the room, such as wall thickness, the area of ​​actual contact between the wall and the outside world, and the overall surface area of ​​the room. At the same time, the heat dissipation rate at a certain moment can be calculated based on the temperature difference between indoors and outdoors.

[0035] As an optional embodiment of the present application, the construction parameters of the target room include: the actual contact area of ​​the target room with the outside world, the overall surface area of ​​the target room and the average wall thickness of the target room, and calculating the heat dissipation rate of the target room at multiple moments after the initial moment based on the indoor temperature, outdoor temperature and construction parameters includes: calculating a first ratio of the actual contact area to the overall surface area, and a first difference between the indoor temperature and the outdoor temperature at a moment; determining the product of the first ratio and the first difference and the second ratio of the average wall thickness as the heat dissipation rate at a moment.

[0036] Specifically, the actual contact area refers to the sum of the areas of the room's walls, roof, windows and floor that are in contact with the outside world. The overall surface area of ​​the target room refers to the sum of the areas of the roof, walls and windows. The average wall thickness refers to the average of the thickness of each wall. For example, if the room has four walls, the average wall thickness is the average of the thickness of the four walls. The heat dissipation rate at a certain moment can be calculated using the following formula:

[0037]

[0038] In the above formula, F k S is the heat dissipation rate of the room corresponding to the sampling time k during the heating process of the indoor heating system. c The actual contact area of ​​the room with the outside world, S z For the overall surface area of ​​the room. The average wall thickness of this room is is the indoor temperature at time k, is the outdoor temperature at time k. Therefore It represents the relative contact area between the room and the outside world. The larger the value, the greater the heat conduction loss in the room, and the greater the heat dissipation rate at this moment. This is the average thickness of the room's walls. The thicker the room's walls are, the slower the heat conduction will be, and the corresponding heat dissipation rate will be smaller. It represents the temperature difference between indoor and outdoor of the room at this moment. The rate of heat conduction is positively correlated with the size of the temperature difference between indoor and outdoor. Therefore, the greater the temperature difference between indoor and outdoor at this moment, the greater the corresponding heat dissipation rate.

[0039] Step S107, determining the time at which the indoor temperature of the target room needs to be adjusted according to the heat dissipation rate and the indoor temperature at each time after the initial time.

[0040] Specifically, when the outdoor temperature begins to drop, the thermal inertia of the building will cause the indoor temperature to lag behind the outdoor temperature, and the corresponding indoor temperature will not have an obvious downward trend. Therefore, the indoor temperature needs to be adjusted in advance. Based on the changing characteristics of the indoor and outdoor temperature data, it is impossible to determine the time when advance adjustment is required. At this time, the heat dissipation rate of the room represents the real-time response ability of the room's heat to the outside temperature. The time when advance adjustment is required can be determined based on the heat dissipation rate.

[0041] Furthermore, since the drop in outside temperature will cause the heat dissipation rate of the house to increase, and the inside of the house cannot keenly perceive this temperature change, the heating system cannot be adjusted in time, causing the indoor temperature to drop. In order to maintain the constant indoor temperature, it is necessary to increase the heating rate within the effective time after the outside temperature drops, so as to avoid adjusting after the indoor temperature has dropped, thereby ensuring the constant room temperature.

[0042] If the outdoor temperature of the room begins to drop, the heat dissipation rate of the house begins to increase. However, due to the thermal inertia of the house building, the indoor temperature will not drop significantly immediately with the increase of the heat dissipation rate, but only slightly. In general, the indoor heating system is not sensitive to such a slow temperature drop, so the heating rate of the indoor heating system remains basically unchanged. In order to determine the adjustment time, the embodiment of the present application performs calculation based on the heat dissipation rate and the indoor temperature.

[0043] As an optional embodiment of the present application, determining the adjustment time when the indoor temperature of the target room needs to be adjusted according to the heat dissipation rate and the indoor temperature at each moment after the initial moment includes: respectively determining the heat dissipation rate and the indoor temperature at the first moment and the second moment after the initial moment; determining the average heat dissipation rate difference and the average temperature difference of the indoor temperature at any two adjacent time points after the initial moment and before the second moment; determining the delay confidence at which the indoor temperature of the target room needs to be adjusted according to the heat dissipation rate and the indoor temperature at the first moment, the heat dissipation rate and the indoor temperature at the second moment, the average heat dissipation rate and the average temperature difference; determining the temperature adjustment delay according to the delay confidence; determining the adjustment time when the indoor temperature of the target room needs to be adjusted based on the temperature adjustment delay, the initial moment and the sampling interval.

[0044] Specifically, the first moment and the second moment may be adjacent moments, and the heat dissipation rate and indoor temperature of a plurality of consecutive adjacent moments may be collected starting from the initial moment. There may be a plurality of time points between the second moment. Among them, the average heat dissipation rate is the average value of the difference in heat dissipation rate between each two adjacent time points after the initial moment and before the second moment. The average temperature difference is the average value of the difference in indoor temperature between each two adjacent time points after the initial moment and before the second moment.

[0045] When determining the delay confidence, it can be determined in the following manner: calculate the second difference between the indoor temperature at the first moment and the indoor temperature at the second moment, and the third difference between the heat dissipation rate at the first moment and the heat dissipation rate at the second moment; calculate the third ratio of the second difference to the average temperature difference, the fourth ratio of the third difference to the average heat dissipation rate, and the fifth ratio of the heat dissipation rate at the first moment to the indoor temperature; calculate the product of the third ratio, the fourth ratio and the fifth ratio, and normalize the product to obtain the delay confidence.

[0046] Specifically, if the outdoor temperature continues to drop from time t0 (initial time), then for any sampling time after time t0, the delay confidence can be calculated using the following formula:

[0047]

[0048] In the above formula, Y zis the delay confidence corresponding to the zth sampling time after time t0. z is the heat dissipation rate at the zth sampling moment (the second moment) after t0, F z-1 is the heat dissipation rate at the z-1th sampling moment (the first moment), is the indoor temperature at the zth sampling moment after t0, is the indoor temperature at the z-1th sampling moment after t0. and It is the average temperature difference of the indoor temperature between any two adjacent sampling moments from time t0 to time z before the sampling moment and the average heat dissipation rate difference of the heat dissipation efficiency, and norm() represents normalization.

[0049] Furthermore, represents the longitudinal difference between the heat dissipation rate and the indoor temperature at the zth sampling moment after time t0. As the outdoor temperature decreases, the heat dissipation rate increases accordingly, while the indoor temperature does not change significantly. Therefore, if The larger the value of , the more obvious the heat dissipation rate at the corresponding moment is relative to the room temperature level, so it is more appropriate to adjust the indoor temperature at this moment, and therefore the greater the delay confidence.

[0050] Furthermore, It represents the horizontal difference between the heat dissipation rate and the indoor temperature at the zth sampling moment after time t0. By comparing the average difference in heat dissipation rate and the average difference in indoor temperature at the historical adjacent sampling moments before the zth sampling moment with the indoor temperature difference and heat dissipation rate difference at time z, the larger the value, the greater the change degree of the heat dissipation rate and indoor temperature at the zth sampling moment is than the historical change degree before the zth sampling moment, indicating that the indoor temperature drops more and more obviously, the corresponding necessity of adjusting the indoor temperature in advance is greater, and the corresponding delay confidence is greater. Finally, the result is normalized to the range of [0,1].

[0051] After determining the delay confidence, the first moment after the initial moment when the delay confidence is greater than a threshold value may be selected as the temperature adjustment delay.

[0052] Specifically, the threshold can be selected according to the actual situation, and the embodiment of the present application is not limited here. For example, the threshold can be 0.9, and the first Y after time t0 is selected. z >0.9 corresponds to the sampling time of the temperature adjustment delay in the current actual scenario.

[0053] Further, after the temperature adjustment delay is obtained, the adjustment time when the indoor temperature of the target room needs to be adjusted is determined based on the temperature adjustment delay, the initial time and the sampling interval. Specifically, the following formula can be used for calculation:

[0054] t e =t0+a×z

[0055] In the above formula, t e is the adjustment time, t0 is the initial time, a is the sampling interval, and z is the temperature adjustment delay. Wherein, a can be determined according to the actual sampling interval, such as a=0.2.

[0056] Step S109, determining the temperature adjustment coefficient at the adjustment time based on the indoor temperature corresponding to the adjustment time, the heat dissipation rate corresponding to the adjustment time, the indoor temperature at a certain time among multiple times, and the minimum value of the heat dissipation rate at the sampling time before the adjustment time.

[0057] The temperature adjustment coefficient indicates the degree of difference between the indoor and outdoor temperature of the target room, and the temperature adjustment coefficient is proportional to the degree of difference between the indoor and outdoor temperature.

[0058] Specifically, the indoor temperature will not drop significantly when the indoor temperature is adjusted in advance, and adjusting the indoor temperature of the room simply based on the heat dissipation rate will cause the indoor temperature to continue to rise, which is not conducive to the constant room temperature. Therefore, it is necessary to comprehensively determine the temperature adjustment coefficient at the adjustment time based on the degree of drop in the indoor temperature and the heat dissipation rate.

[0059] As an optional embodiment of the present application, based on the indoor temperature corresponding to the adjustment time, the heat dissipation rate corresponding to the adjustment time, the indoor temperature at a certain time among multiple times and the minimum value of the heat dissipation rate at the sampling time before the adjustment time, determining the temperature adjustment coefficient at the adjustment time includes: respectively calculating the sixth ratio of the initial time and each time within the adjustment time to the temperature adjustment delay; superimposing each ratio to obtain a superimposed value; determining the sum of the indoor temperature corresponding to the adjustment time and the constant, and the reciprocal of the absolute value of the seventh ratio of the sum and the superimposed value; calculating the fourth difference between the heat dissipation rate corresponding to the adjustment time and the minimum value of the heat dissipation rate at the sampling time before the adjustment time; calculating the product of the reciprocal and the fourth difference, and normalizing the product to obtain the temperature adjustment coefficient.

[0060] Specifically, if the indoor temperature needs to be adjusted at a time t e =t0+0.2z, then the temperature adjustment coefficient at the adjustment time can be calculated using the following formula:

[0061]

[0062] In the above formula, t e The temperature adjustment coefficient corresponding to the time. t e The indoor temperature corresponding to the time, is the indoor temperature corresponding to the kth moment after t0. t e The heat dissipation rate corresponding to the moment, min(F) is t e The minimum value of the heat dissipation rate at the historical sampling moment before the moment. sigmoid() represents a normalization function, and b is a constant, which can be determined according to the actual scenario. It is mainly to prevent the indoor temperature from being 0 or extremely close to 0, which causes a large change in the value. Specifically, the b value can be 10, which is not limited in the embodiment of the present application.

[0063] therefore, Represents t e The greater the value, the smaller the change in indoor temperature at the corresponding moment, and the smaller the corresponding temperature adjustment coefficient when adjusting. t e The relative value of the heat dissipation rate corresponding to the time relative to the minimum value of the heat dissipation rate at the historical sampling time. Since the heat dissipation rate is determined by the temperature difference between indoor and outdoor, The larger the t e The greater the indoor and outdoor temperature difference at the moment, the greater the corresponding temperature adjustment coefficient. Finally, the result is normalized to the range of [0,1] by the sigmoid function as the temperature adjustment coefficient.

[0064] Step S1011, determining the heating rate at the adjustment time according to the temperature adjustment coefficient and the heating rate at the moment before the adjustment time, so as to adjust the indoor temperature in the target room based on the heating rate.

[0065] Specifically, the above steps have obtained the adjustment time and temperature adjustment coefficient for the indoor temperature to be adjusted in advance by the indoor heating system when the outside temperature drops. Therefore, it is necessary to adjust the heating rate of the indoor heating system based on the temperature adjustment coefficient, so that the indoor heating system can adjust the indoor temperature based on the heating rate.

[0066] As an optional embodiment of the present application, determining the heating rate at the adjustment time according to the temperature adjustment coefficient and the heating rate at the moment before the adjustment time includes: calculating the sum of the preset value and the temperature adjustment coefficient; determining the product of the heating rate at the moment before the adjustment time and the sum as the heating rate at the adjustment time. The preset value can be determined according to actual conditions, and the embodiment of the present application is not limited here. For example, the preset value can be 1.

[0067] Specifically, if the indoor temperature needs to be adjusted at a time t e =t0+0.2z, then the heating rate can be calculated using the following formula:

[0068]

[0069] In the above formula, is the time t when indoor temperature adjustment is required e The corresponding heating rate is t e The moment before time t e -1 corresponds to a heating rate, t e The temperature adjustment coefficient corresponding to the moment. Therefore, the above method can be used to adjust the temperature from t e The room's heating rate is adaptively increased at all times to ensure a stable room temperature.

[0070] The embodiment of the present application can calculate the real-time heat dissipation rate through the construction parameters of the room and the temperature difference between indoor and outdoor temperatures, and then determine the adjustment time and the corresponding temperature adjustment coefficient required for temperature adjustment based on the heat dissipation rate, so as to adjust and control the heating rate of the indoor heating system in advance, avoiding the room temperature drop caused by the lag in regulation, thereby making the indoor temperature control more precise and ensuring the stability of the indoor temperature during heating, which not only improves the comfort of the living and working environment, but also improves the energy utilization rate.
