Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a region control method includes step S100, step S200, and step S300.
Step S100, a temperature parameter related to the current temperature of the target area is acquired.
Specifically, the target area is an area where temperature regulation by controlling the damper is required. The air valve is an air volume adjusting valve, is an indispensable end fitting in ventilation, air conditioning and air purification projects of industrial factory buildings and civil buildings, is generally used in ventilation system pipelines such as air conditioners and the like, is used for adjusting the air volume of branch pipes, and can also be used for mixed adjustment of fresh air and return air. In the regional control scheme of the air conditioning system, each region is correspondingly provided with an air valve and is respectively connected with an air valve interface of an air valve controller, the opening degrees of the air valves in different regions are controlled through the air valve controllers, different amounts of cold air or hot air are conveyed to the different regions, and therefore temperature adjusting operation of the different regions is achieved. In order to meet different user requirements of cold air or hot air conveyed by the air valve, the temperature in different areas reaches the expected temperature of a user, and the air valve controller can also receive temperature data collected by temperature controllers arranged in different areas in real time in the area control scheme, so that the corresponding air valve is subjected to feedback regulation. It should be noted that the number of temperature controllers in the same area is not exclusive, and one or more temperature controllers may be specifically set according to the size of the area and the user requirement.
However, in the actual operation of the air conditioning system, the thermostat may malfunction due to improper operation, and when the temperature control malfunctions, the temperature data corresponding to the area cannot be collected and sent to the damper controller, and the damper controller cannot reasonably control the damper of the malfunctioning area. Aiming at the situation that the temperature controller is easy to break down, the scheme adopts the area controller to acquire the temperature parameter of the target area (namely the fault area) for analysis and calculation to obtain the initial temperature of the area where the temperature controller breaks down, namely the current temperature value of the fault area, replaces the traditional mode that the temperature controller collects the current temperature data, and then carries out further control operation of the underground air valve. It will be appreciated that the type of temperature parameter is not exclusive, as long as it is a parameter that enables the initial temperature calculation of the fault region.
And step S200, obtaining the initial temperature of the target area according to the temperature parameter and the preset temperature difference value.
Specifically, the preset temperature difference value is a difference value between the outdoor temperature of the target area and the indoor temperature of the non-target area when the air valve of the area control system is not opened. The initial temperature is the current temperature value of the target area before judging whether the air valve needs to be opened for temperature adjustment, and when the air valve is opened to supply cold air or hot air to the target area, the temperature of the target area is adjusted on the basis of the initial temperature. Under normal conditions, namely when no relatively large heating source or refrigerating source exists indoors, the air conditioning system is started, and the difference value between the indoor temperature of the non-target area and the outdoor temperature of the target area is the preset temperature difference value. Further, in one embodiment, when a plurality of non-target zones are included in the zone control system, the indoor temperature of the corresponding non-target zone will be the average of the indoor temperatures of the respective non-target zones.
It should be noted that the magnitude of the preset temperature difference value is also different for different use regions of the air conditioning system or different seasons. For example, in summer, the outdoor temperature and the indoor temperature may differ by 5 ℃ in a sunny day, and the indoor temperature and the outdoor temperature may differ by only 1 ℃ in a rainy day without opening the air valve; in autumn, the climate is pleasant, and the indoor temperature and the outdoor temperature are similar, namely the preset temperature difference value is very small. Therefore, the specific preset temperature difference value can be set by the user by integrating factors such as the environment, the season and the like of the user. It can be understood that when the obtained temperature parameters of the target area are inconsistent, there may be a certain difference in the manner of obtaining the initial temperature of the target area by analyzing according to the target parameter and the preset temperature difference value, as long as the initial temperature of the target area can be reasonably obtained.
And step S300, carrying out comparative analysis according to the initial temperature and the preset temperature, and controlling the opening and closing of an air valve of the target area according to the analysis result.
Specifically, the preset temperature is a temperature value of a target area expected to be reached by a user, and after the area controller obtains an initial temperature of the target area according to the temperature parameter and the preset temperature difference value, the initial temperature and the preset temperature difference value are compared and analyzed, so that information about whether the air valve needs to be opened is obtained. It should be noted that, in one embodiment, the zone controller is not directly connected to the air valve, and the corresponding zone controller is connected to the air valve through the air valve controller, and when the zone controller obtains information that the air valve needs to be opened according to the initial temperature and the preset temperature, the zone controller sends a control signal to the air valve controller, and then the air valve controller is used for realizing the opening operation of the air valve. The zone control method can realize the air valve control operation of the fault zone with the temperature controller having faults, and also can be applied to the air valve control operation of the target zone with the temperature controller running normally.
It can be understood that the preset temperature is not unique, and may be set differently according to the user's own needs or the current season. For example, in one embodiment, the preset temperature is 16 ℃ to 30 ℃. Further, in the case that the air conditioning system is in a cooling or heating state, the magnitude relationship between the initial temperature and the preset temperature is consistent, and the corresponding air valve control operation is also different.
For example, referring to fig. 2, in one embodiment, step S300 includes step S310 and step S320.
In step S310, in the cooling state, if the initial temperature is greater than the preset temperature, the damper of the target area is controlled to be opened.
Specifically, in the cooling state, the air conditioning system will deliver cold air to each area, and if the initial temperature is greater than the preset temperature, it indicates that the temperature of the target area is too high and does not meet the temperature expected by the user. If the air valve of the target area is not opened, the area controller controls the air valve of the target area to be opened through the air valve controller, so that cold air is conveyed to the target area, the temperature of the target area is reduced, and the temperature of the target area is reduced until the temperature of the target area reaches the temperature expected by a user, namely the preset temperature. If the air valve controller is in an open state at the moment, the area controller does not send any control signal to the air valve controller or sends a control signal for maintaining the opening to the air valve controller, so that the operation of conveying cold air to the target area is realized.
In step S320, if the initial temperature is less than or equal to the preset temperature, the damper of the target area is controlled to be closed.
Specifically, in the refrigeration state, if the temperature of the target area is rainy or equal to the preset temperature when the air valve is not opened, it indicates that the temperature of the target area meets the expected temperature of the user, at this time, the air valve does not need to be opened, and the area controller does not need to send an opening signal to the wind generator control, so that the air valve of the target area can be maintained in the closed state. Or when the air valve is opened, the area controller sends a closing control signal to the air valve controller to control the air valve to be closed, and the air valve stops conveying cold air to the target area.
With continued reference to fig. 2, in one embodiment, step S300 includes step S330 and step S340.
In step S330, in the heating state, if the initial temperature is lower than the preset temperature, the damper in the target area is controlled to be opened.
Specifically, similar to the cooling state, when the air conditioning system is in the heating state, if the area controller performs comparative analysis according to the initial temperature and the preset temperature, and the obtained initial temperature is lower than the preset temperature, it indicates that the temperature of the target area does not reach the temperature expected by the user. When the air valve is in a closed state, the area controller sends an opening control signal to the air valve controller, and the air valve controller controls the air valve to open, so that hot air is conveyed to the target area until the temperature of the target area reaches a preset temperature. If the air valve is in the opening state, the area controller does not send any control signal to the air valve controller or sends a signal for maintaining opening to the air valve controller, so that hot air can be conveyed to a target area, and heating operation is realized.
In step S340, if the initial temperature is greater than or equal to the preset temperature, the damper of the control target area is closed.
Specifically, if the initial temperature in the heating state is greater than or equal to the preset temperature, it indicates that the temperature of the target area has reached the temperature expected by the user, and at this time, it is not necessary to continue to deliver hot air to the target area for heating operation. If the air valve of the target area is in a closed state, the area control does not send any control signal to the air valve controller or sends a control signal for maintaining opening to the air valve controller; and if the air valve of the target area is in an open state, the area controller sends a closing control signal to the air valve controller to control the air valve to be in a closed state, and the hot air is stopped being conveyed to the target area.
Referring to fig. 3, in an embodiment, after step S300, the method further includes step S400, step S500 and step S600.
And step S400, acquiring an average value of the temperature change rate when the air valve of the target area is opened.
Specifically, the average value of the temperature change rates is an average value of the corresponding temperature change rates after the air valve of the target area is opened within the preset historical days. The operating state of the air conditioning system is substantially consistent for the same target area in a short time, and therefore, it is possible to adopt a method of calculating the rate of change of the temperature of the target area when the damper of the target area is opened within a preset historical number of days. It can be understood that the temperature control is in a stable operation state within the selected historical days, so that the temperature change rate can be calculated according to the change value of the temperature data collected by the temperature controller and the corresponding time and stored in the zone controller. When the average value of the temperature change rate needs to be calculated, the zone controller only needs to extract the corresponding temperature change rate for calculation, and then the corresponding average value is obtained.
It should be noted that the setting of the preset historical number of days is not exclusive as long as the selected time period is substantially consistent with the operating environment of the air conditioning system at the current time point. For example, in one embodiment, the temperature change rates of the previous days of the current time point are selected for calculation, and the average of the temperature change rates of the previous days is obtained. Namely, it isWhereinIs the average value of the temperature change rate, N represents the number of days, VNIndicating the corresponding temperature change rate N days before the current time point. Further, in a specific embodiment, the user selects the current temperature change rate of 7 days to calculate the average value of the temperature change rates, so as to obtain the average value
And step S500, obtaining the predicted running time of the air valve in the target area according to the average value of the temperature change rate.
Specifically, the predicted operation time is a time predicted to be required for increasing or decreasing the temperature of the target area to a preset temperature at the current damper opening degree, and the predicted time is in inverse proportion to the damper opening degree, that is, the larger the damper opening degree is, the smaller the predicted operation time is. The air valve is a valve, and the percentage of the opening of the valve can be controlled by some physical structures, such as half 50% of the opening of the air valve. Taking refrigeration as an example, if the damper is 100% open, the average rate of change of temperature in the zone can be reduced by 1 ℃ per minute, and if the damper is 50% open, the average rate of change of temperature in the zone can be reduced by 1 ℃ per two minutes.
That is, the average value of the temperature change rate is not unique, and the average value of the temperature change rate is different under different opening degrees of the air valves. In order to obtain an accurate average value of the temperature change rate, in one embodiment, the corresponding average value of the temperature change rate is obtained by using the similar method for different opening degrees of the air valves, so as to facilitate the subsequent calculation of the predicted operation time. In another embodiment, after the average value of the temperature change rate of a certain air valve opening is calculated by the above method, the average value of the temperature change rate corresponding to each opening can be obtained according to the relationship between the actual air valve opening and the air valve opening used for calculation.
In the actual operation process, the zone controller may adjust the time required for the target zone to reach the temperature desired by the user by adjusting the opening degree of the damper, and for the convenience of understanding the present embodiment, the following explanation is made on cooling in the specific embodiment. If the zone controller calculates that the initial temperature is 25 deg.c and the preset temperature is 20 deg.c, it means that the temperature of the target zone needs to be lowered by 5 deg.c during the cooling process. When the area controller controls the air valve opening of the target area to be 50% through the air valve controller to operate and sends cold air to the target area, the average value of the temperature change rate of the state is reduced by 1 ℃ every two minutes, and the estimated operation time of the air valve at the time can be calculated to be 10 min. When the area controller controls the air valve opening of the target area to be 100% through the air valve controller and sends cold air to the target area, the average value of the temperature change rate of the state is reduced by 1 ℃ per minute, and the estimated running time of the air valve at the time can be calculated to be 5 min.
And step S600, when the predicted running time is reached, closing the air valve of the control target area.
Specifically, after the area controller analyzes the average value of the temperature change rates and the corresponding opening degree of the air valve to obtain the predicted operation time for opening the air valve, the area controller starts to time, and after the predicted operation time is ended, the area controller indicates that the air valve is opened to operate so that the temperature of the target area reaches the preset temperature. At the moment, the air valve does not need to continuously operate to adjust the temperature of the target area, and in order to save energy, the area controller sends a closing control signal to the air valve controller, so that the air valve is controlled to be closed, and the operation of conveying hot air or conveying cold air is finished. It is understood that the operation of controlling the air valve to close again in the present embodiment may be the heating or cooling operation, and the hot air delivery or the cold air delivery is realized by opening the air valve in both the heating and cooling operations.
In one embodiment, the temperature parameters include an indoor ambient temperature of an area where the damper is not opened, a current outdoor ambient temperature of the target area, and a preset average value of the indoor ambient temperature, and the step S200 includes: wherein, T0Is the initial temperature, T1Room ambient temperature, T, in the area of the unopened flap2Is the current outdoor ambient temperature, T, of the target area3The average value of the preset indoor environment temperature of the target area is delta, and delta is a preset temperature difference value.
In particular, as mentioned above, the type of temperature parameter is not exclusive, and the initial temperature calculation manner may be different for different types of temperature parameters. The preset indoor environment temperature average value of the target area is an average value obtained by calculation according to the indoor environment temperature of the target area every day in the latest period of time. It is understood that in order to make the finally calculated initial temperature sufficiently accurate, when the calculation of the preset indoor ambient temperature of the target area is performed, the calculation is performed using indoor temperature data for a period of time closest to the current time point.
The current outdoor environment temperature of the target area is not only obtained, but also directly input by a user or acquired by a temperature data acquisition device of an outdoor unit of the air conditioning system. It should be noted that in one embodiment, the indoor ambient temperature T of the area where the damper is not open1The obtaining method of (1) is not unique, and may be an indoor ambient temperature corresponding to a certain area where the damper is not opened, or an average value of indoor ambient temperatures corresponding to a plurality of areas where the damper is not opened. According to the method, the initial temperature is calculated through three dimensions, namely the indoor environment temperature of the area without the air valve, the current outdoor environment temperature of the target area and the preset internal environment temperature of the target area, and the method has the advantage of high accuracy of the calculation result.
In one embodiment, the temperature parameter includes a current outdoor ambient temperature and a preset indoor ambient temperature average value of the target area, and the step S200 includes:wherein, T0Is the initial temperature, T2Is the current outdoor ambient temperature, T, of the target area3The average value of the preset indoor environment temperature of the target area is delta, and delta is a preset temperature difference value.
Specifically, similar to the initial temperature calculation in the three dimensions, the dimension data of the indoor environment temperature of the area where the air valve is not opened currently may not be obtained because the air valve is opened in the rest areas. In the embodiment, for such a situation, the dimension of the indoor environment temperature of the area without opening the damper is reduced, and the initial temperature corresponding to the target area can be obtained, so that the subsequent analysis processing is performed.
Referring to fig. 4, in an embodiment, before step S100, the method further includes step S110.
Step S110, detecting whether temperature data collected by the temperature controller of the target area is received.
Specifically, each region all corresponds and is provided with the temperature controller, directly carries out the temperature data acquisition in corresponding region through the temperature controller, then directly carries out the analysis with predetermineeing the temperature according to the temperature data of gathering, can be with the information whether need open the blast gate directly perceived. In this embodiment, in the region that the temperature controller did not break down, directly carry out the blast gate control through the temperature data that the temperature controller gathered, and only just carry out the blast gate control according to the mode of calculating initial temperature in the region that the temperature controller broke down, when guaranteeing regional control system steady operation, still have stronger operational reliability.
If it is determined in step S110 that the temperature data collected by the thermostat of the target area is detected, that is, if yes, step S120 is performed. And step S120, controlling the opening and closing of the air valve in the target area according to the temperature data collected by the temperature controller and the preset temperature.
Specifically, if yes, it is indicated that the temperature controller in the target area does not have a fault, the temperature data collected and sent by the temperature controller in the target area can be detected by the area controller, and the area controller can directly perform comparative analysis on the temperature data and the preset temperature, so that the temperature of the target area is adjusted to be consistent with the preset temperature. If it is determined that the temperature data collected by the temperature controller in the target area is not detected according to step S110, that is, if not, step S100 is performed. It can be understood that, if not, it indicates that the temperature controller has a fault at this time, and current temperature data of the target area cannot be acquired, and the area controller starts a standby control scheme, and further performs analysis processing by acquiring a temperature parameter related to the current temperature of the target area, so as to obtain an initial temperature for representing the current temperature of the target area, and perform subsequent temperature adjustment operation of the target area.
According to the area control method, when the temperature of the target area is adjusted, the temperature parameter related to the current temperature of the target area is obtained firstly, and then analysis is carried out according to the temperature parameter and the preset temperature difference value, so that the initial temperature corresponding to the target area at the moment is obtained. And finally, only the initial temperature and the preset temperature are needed to be compared and analyzed, and the information whether the air valve of the target area needs to be opened or not can be obtained. The operation of opening or closing the air valve of the target area is realized through the scheme, and the current temperature data of the target area is not required to be acquired through a temperature controller. Even if the temperature controller of the target area fails, the temperature of the target area can be adjusted by controlling the opening or closing of the air valve, and the temperature controller has the advantage of high control reliability.

The specific operation is similar to the embodiment corresponding to the above method, and is not described herein again.
According to the area control method, when the temperature of the target area is adjusted, the temperature parameter related to the current temperature of the target area is obtained firstly, and then analysis is carried out according to the temperature parameter and the preset temperature difference value, so that the initial temperature corresponding to the target area at the moment is obtained. And finally, only the initial temperature and the preset temperature are needed to be compared and analyzed, and the information whether the air valve of the target area needs to be opened or not can be obtained. The operation of opening or closing the air valve of the target area is realized through the scheme, and the current temperature data of the target area is not required to be acquired through a temperature controller.

Referring to fig. 7, a local control system includes: the regional controller 10 is used for controlling the opening and closing of the air valve 30 of the target region through the air valve controller 20 according to the method described above, and the regional controller 10 is used for controlling the opening and closing of the air valve 30 of the target region through the air valve controller 20.
Specifically, the air valve 30 is an air volume adjusting valve, is an indispensable end fitting in ventilation, air conditioning and air purification projects of industrial factory buildings and civil buildings, is generally used in ventilation system pipelines such as air conditioners and the like, is used for adjusting the air volume of branch pipes, and can also be used for mixed adjustment of fresh air and return air. In the regional control scheme of the air conditioning system, each region is correspondingly provided with an air valve 30 and is respectively connected with an air valve interface of an air valve controller 20, the opening degrees of the air valves 30 in different regions are controlled through the air valve controller 20, and different amounts of cold air or hot air are conveyed to the different regions, so that the temperature regulation operation of the different regions is realized. In order to meet the requirements of different users by the cold air or the hot air delivered by the air valve 30 and enable the temperatures in different areas to reach the expected temperatures of the users, the air valve controller 20 can receive the temperature data collected by the temperature controllers arranged in different areas in real time in the area control scheme, so that the corresponding air valve 30 is subjected to feedback regulation. It should be noted that the number of temperature controllers in the same area is not exclusive, and one or more temperature controllers may be specifically set according to the size of the area and the user requirement.
However, in the actual operation of the air conditioning system, the thermostat may malfunction due to improper operation, and when the temperature control malfunctions, the temperature data corresponding to the area cannot be collected and sent to the damper controller 20, and the damper controller 20 cannot reasonably control the damper 30 in the malfunctioning area. Aiming at the condition that the temperature controller is easy to break down, the scheme adopts the area controller 10 to obtain the temperature parameter of the target area (namely the fault area) for analysis and calculation to obtain the initial temperature of the area where the temperature controller breaks down, namely the current temperature value of the fault area, replaces the traditional mode that the temperature controller collects the current temperature data, and then carries out the control operation of the air valve 30.

Therefore, the specific preset temperature difference value can be set by the user by integrating factors such as the environment, the season and the like of the user. It can be understood that when the obtained temperature parameters of the target area are inconsistent, there may be a certain difference in the manner of obtaining the initial temperature of the target area by analyzing according to the target parameter and the preset temperature difference value, as long as the initial temperature of the target area can be reasonably obtained.

For example, in one embodiment, the preset temperature is 16 ℃ to 30 ℃. Further, in the case that the air conditioning system is in a cooling or heating state, the magnitude relationship between the initial temperature and the preset temperature is consistent, and the control operation of the corresponding damper 30 is also different.
