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 steps S200, S300, and S400.
Step S200, when a fault area occurs, acquiring the ambient temperature of a non-fault area.
Specifically, the failure area is an area where the temperature controller fails in an area with work requirements, and the non-failure area is an area where the temperature controller normally operates in the area with work requirements. In each region that regional control system corresponds, all be provided with the temperature controller and carry out the ambient temperature collection that corresponds the region in real time, then send the ambient temperature who obtains the collection to the blast gate controller with wireless communication's mode and carry out analysis processes. Further, in one embodiment, each thermostat is in communication connection with the radio frequency module of the air valve controller respectively, so as to send the ambient temperature to the air valve controller through wireless communication. It should be noted that the determination method of the fault area is not unique, and in one embodiment, it may be determined whether each area receives the ambient temperature collected and sent by the corresponding temperature controller in the area with the work requirement, if so, it indicates that the fault area does not exist, and if not, it indicates that the fault area exists.
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 enable cold air or hot air conveyed by the air valve to meet different user requirements and enable the temperature in different areas to reach the expected temperature of users, the air valve controller can also receive temperature data collected by temperature controllers arranged in different areas in real time in a regional 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. For example, in one embodiment, the temperature controllers are arranged in one-to-one correspondence with the air valves, that is, one temperature controller is arranged in each zone of the zone control system for temperature collection, and one air valve is arranged for air supply control.
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. Therefore, the scheme analyzes the acquired environment temperature of the temperature controller in the other areas with work requirements, obtains the temperature matched with the fault area to replace the function of the temperature controller, and further realizes the temperature regulation operation of the fault area.
It should be noted that the area with the work requirement may be an area with a temperature adjustment function by opening the air valve or an area with a temperature adjustment function by opening the air valve, that is, the scheme may be applied to a scenario where a thermostat of an operating area fails during an operation of a zone control system, or a scenario where a thermostat fails exists in an area with a temperature adjustment function by opening the air valve. For the two scenes, the area control method can start an emergency control function so as to ensure that a fault area can carry out reasonable cooling/heating operation.
And step S300, obtaining the start-stop control temperature matched with the fault area according to the environment temperature.
Specifically, the start-stop control temperature is used for analyzing the preset temperature, so as to judge whether the temperature of the air valve for air supply needs to be opened or the temperature of the specific opening degree of the air valve needs to be opened. When the temperature controller of the fault area breaks down, the air valve controller acquires the environment temperature of other non-fault areas and analyzes the environment temperature to obtain the start-stop control temperature which is most matched with the fault area, so that reasonable air supply control is performed on the fault area in subsequent operation. It can be understood that, in the area control scheme in which the temperature controller does not have a fault, the start-stop control temperature is the ambient temperature of the corresponding area, that is, in this embodiment, the start-stop control temperature representing the ambient temperature of the fault area is obtained by analyzing the ambient temperature of the non-fault area, and further air supply control operation is performed.
It should be noted that, because the solution needs to acquire the ambient temperature of the non-failure area, and the non-failure area also has an air supply requirement, the solution of the present application is applied to a scenario in which most or all areas need to open the air valve for air supply control. For the special condition that only one area needs to carry out air supply control and the area is a fault area, the air valve controller only needs to replace the temperature controllers of other areas to the fault area, and the stable operation of the fault area can be ensured by pairing the air valve with the temperature controllers again.
And S400, performing air supply control on the fault area according to the start-stop control temperature and the preset temperature corresponding to the fault area.
Specifically, after the air valve controller obtains the start-stop control temperature, the air valve controller performs air valve control of the fault area according to the start-stop control temperature and a target temperature (namely a preset temperature) corresponding to the fault area, and realizes air supply operation of the fault area by controlling the opening degree of the opened air valve. The air valve controller can be used for intelligently controlling the air valve of a fault area to operate at an opening with a proper size according to the relation between the start-stop control temperature and the preset temperature, the operation condition of the air conditioning unit and the like, and the specific control mode is similar to the air supply control of a non-fault area according to the environment temperature and the corresponding preset temperature.
Referring to fig. 2, in one embodiment, step S300 includes step S330.
In step S330, when there is a non-failure region having a region area matching the failure region, the ambient temperature corresponding to the non-failure region having a region area matching the failure region is used as the start-stop control temperature.
Specifically, in the present embodiment, the start-stop control temperature is the ambient temperature of the non-failure region whose area is closest to the area of the failure region. It can be understood that the matching of the area areas is that the difference between the area areas is small, and within the allowable range of the difference, because the difference between the area areas is small or the difference between the heat preservation effect and the temperature change trend of two identical areas is not large or even basically consistent in the same area control system, the ambient temperature of the non-fault area with the matched area can be used as the start-stop control temperature of the fault area. The ambient temperature of each non-fault area and the area of each non-fault area can be known through the air valve controller, the non-fault area matched with the area of the area and the fault area is found through comparison operation among the areas, and then air supply control operation of the fault area can be carried out according to the ambient temperature corresponding to the non-fault area.
In one embodiment, matching the area of the regions is within the tolerance, and two regions can be considered equal, for example, the difference between the areas is within ± 1 square meter, i.e., two regions can be considered to match. It should be noted that, when there are many non-failure regions whose area matches the area of a failure region, the ambient temperature corresponding to the non-failure region whose difference between the area of the region and the area of the failure region is the smallest is selected as the start-stop control temperature. For example, in one embodiment, the area difference corresponding to the first non-failure region is 0.5 square meter, and the area difference corresponding to the second non-failure region is 0.4 square meter, and then the ambient temperature corresponding to the second non-failure region is taken as the start-stop control temperature.
Referring to fig. 2, in an embodiment, before step S330, step S300 further includes step S310 and step S320.
In step S310, the area of the failure region and the area of the non-failure region are acquired.
Specifically, the area control terminal of the area control system is preset with the area corresponding to each area, that is, in the actual operation process, the user may preset the area of each area corresponding to the entire area control system in the area control terminal. When a fault area occurs and the air valve controller needs to realize the air supply control of the fault area through an emergency control scheme, the area of a non-fault area and the area of the fault area can be obtained through accessing an area control terminal, and then further analysis operation is carried out.
It is understood that in other embodiments, devices for measuring areas or manually inputting areas by a user may be disposed in different areas of the area control system, and when the emergency control scheme needs to be activated, the area of the corresponding area is sent to the air valve controller through the device corresponding to the failed area and the device corresponding to the non-failed area, so that the air valve controller may analyze the area of the non-failed area closest to the area of the failed area.
Step S320, determining whether there is a non-failure region having a region area matching the failure region according to the region area of the failure region and the region area of the non-failure region.
Specifically, after the blast gate controller obtains the area of each non-fault region and the area of the fault region, the area of each non-fault region and the area of the fault region are compared and analyzed, so that whether a non-fault region with the area matched with the fault region exists or not can be judged. If the temperature of the ambient temperature in the non-failure region exists, the air supply control can be performed by using the ambient temperature in the non-failure region as the start-stop control temperature in the failure region.
It should be noted that the specific determination manner of the area of the region is not exclusive, for example, in an embodiment, the step of determining whether there is a non-failure region whose area matches the failure region according to the area of the failure region and the area of the non-failure region includes: respectively subtracting the area of the non-fault area from the area of the fault area to obtain different area difference values, and judging whether the area difference values meeting the preset area threshold value condition exist or not; and if so, taking the non-fault area corresponding to the area difference value meeting the preset area threshold value condition as the non-fault area matched with the fault area.
Specifically, in this embodiment, a difference comparison method is adopted to obtain the area of each non-failure region and the area of the failure region, and then the obtained area difference values are respectively compared with the preset area threshold condition. It should be noted that the size of the preset area threshold condition is not unique, for example, in one embodiment, the preset area threshold condition is ± 1 square meter, i.e., the difference between the area of the region where the non-failure region exists and the area of the failure region does not exceed 1 square meter, and the non-failure region where the area of the region matches the failure region is considered to exist. It can be understood that if the area difference value does not exist, that is, the area difference value does not satisfy the preset area threshold condition, it is determined that there is no non-failure area in which the area of the area matches the failure area.
Referring to fig. 2, in an embodiment, after the step S320, the method further includes a step S340.
And step S340, when no non-fault region with the region area matched with the fault region exists, taking the average value of the environment temperature as the start-stop control temperature.
Specifically, in the present embodiment, the start-stop control temperature is an average value of the ambient temperatures of all the non-failure regions. When analysis is performed based on the area of the non-failure region and the area of the failure region, there may be no non-failure region having an area matching the failure region due to a large difference in the area of each region. At the moment, a proper start-stop control temperature cannot be directly obtained for control, and the air valve controller can be combined with all the environment temperatures to obtain a proper start-stop control temperature for distribution control. The air valve controller calculates according to the ambient temperatures of all non-fault areas to obtain the average value of all the ambient temperatures, the average value is used as the start-stop control temperature, and then the analysis is carried out by combining the preset temperature, so that the reasonable air supply control of the fault area can be realized.
Referring to fig. 3, in an embodiment, before step S400, the method further includes step S100.
And S100, acquiring a preset temperature corresponding to the fault area.
Specifically, the preset temperature is set by a user through the zone control terminal. When the air conditioner group is connected into the regional control system, the user can set the corresponding preset temperatures of different regions according to the requirements of the user through the regional control terminal, and meanwhile, when the air valve controller has the requirements, the regional control terminal can send the different preset temperatures set by the user to the air valve controller. It can be understood that when the air valve controller accesses the area control terminal, the area control terminal can send all the preset temperatures to the air valve controller, and the air valve controller selects the preset temperature corresponding to the fault area according to the requirement. In another embodiment, when the air valve controller accesses the area control terminal, the area control terminal only sends the preset temperature corresponding to the fault area to the air valve controller to perform air supply control of the fault area.
According to the regional control method, when a regional control system has a fault region in the operation process, the emergency control function is started, the environment temperature corresponding to the non-fault region at the moment is obtained through the air valve controller and analyzed, and the start-stop control temperature matched with the fault region is obtained and used for representing the current environment temperature corresponding to the fault region at the moment. And then the air valve controller performs air supply control on the fault area according to the preset temperature (namely the target temperature) corresponding to the fault area and the current environment temperature. By the scheme, reasonable operation of the fault area can be controlled, so that basic refrigeration or heating requirements of the fault area are maintained, the situation that the air valve controller cannot reasonably control the operation condition of the fault area is avoided, and the air valve controller has the advantage of high control reliability.
Referring to fig. 4, a local control apparatus includes: the system comprises an ambient temperature acquisition module 200, a start-stop control temperature analysis module 300 and an air supply control module 400.
The ambient temperature acquiring module 200 is configured to acquire an ambient temperature of a non-failure area when a failure area occurs.
Specifically, the failure area is an area where the temperature controller fails in an area with work requirements, and the non-failure area is an area where the temperature controller normally operates in the area with work requirements. In each region that regional control system corresponds, all be provided with the temperature controller and carry out the ambient temperature collection that corresponds the region in real time, then send the ambient temperature who obtains the collection to the blast gate controller with wireless communication's mode and carry out analysis processes.
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. Therefore, the scheme analyzes the acquired environment temperature of the temperature controller in the other areas with work requirements, obtains the temperature matched with the fault area to replace the function of the temperature controller, and further realizes the temperature regulation operation of the fault area.
It should be noted that the area with the work requirement may be an area with a temperature adjustment function by opening the air valve or an area with a temperature adjustment function by opening the air valve, that is, the scheme may be applied to a scenario where a thermostat of an operating area fails during an operation of a zone control system, or a scenario where a thermostat fails exists in an area with a temperature adjustment function by opening the air valve. For the two scenes, the area control method can start an emergency control function so as to ensure that a fault area can carry out reasonable cooling/heating operation.
The start-stop control temperature analysis module 300 is configured to obtain a start-stop control temperature matched with the fault area according to the ambient temperature.
Specifically, the start-stop control temperature is used for analyzing the preset temperature, so as to judge whether the temperature of the air valve for air supply needs to be opened or the temperature of the specific opening degree of the air valve needs to be opened. When the temperature controller of the fault area breaks down, the air valve controller acquires the environment temperature of other non-fault areas and analyzes the environment temperature to obtain the start-stop control temperature which is most matched with the fault area, so that reasonable air supply control is performed on the fault area in subsequent operation. It can be understood that, in the area control scheme in which the temperature controller does not have a fault, the start-stop control temperature is the ambient temperature of the corresponding area, that is, in this embodiment, the start-stop control temperature representing the ambient temperature of the fault area is obtained by analyzing the ambient temperature of the non-fault area, and further air supply control operation is performed.
The air supply control module 400 is configured to perform air supply control on the fault area according to the start-stop control temperature and a preset temperature corresponding to the fault area.

The air valve controller can be used for intelligently controlling the air valve of a fault area to operate at an opening with a proper size according to the relation between the start-stop control temperature and the preset temperature, the operation condition of the air conditioning unit and the like, and the specific control mode is similar to the air supply control of a non-fault area according to the environment temperature and the corresponding preset temperature.
In one embodiment, the start-stop control temperature analysis module 300 is further configured to, when there is a non-fault region having a region area matching the fault region, use an ambient temperature corresponding to the non-fault region having the region area matching the fault region as the start-stop control temperature.

The respective modules in the area control device described above may be implemented in whole or in part by software, hardware, and a combination thereof. The modules can be embedded in a hardware form or independent from a processor in the computer device, and can also be stored in a memory in the computer device in a software form, so that the processor can call and execute operations corresponding to the modules.

However, in the actual operation of the air conditioning system, the thermostat 40 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. Therefore, according to the scheme, the ambient temperature collected by the temperature controller 40 in the rest areas with work requirements is obtained and analyzed, the temperature matched with the fault area is obtained to replace the function of the temperature controller 40, and then the temperature regulation operation of the fault area is realized.

The start-stop control temperature is used for analyzing the preset temperature, so as to judge whether the temperature of the air valve 30 for air supply needs to be opened or not or the temperature of the specific opening degree of the air valve 30 needs to be opened. When the temperature controller 40 in the fault area has a fault, the air valve controller 20 obtains the ambient temperature of the other non-fault areas and analyzes the ambient temperature to obtain the start-stop control temperature most matched with the fault area, so as to perform reasonable air supply control on the fault area in the subsequent operation. It can be understood that, in the area control scheme where the temperature controller 40 does not have a fault, the start-stop control temperature is the ambient temperature of the corresponding area, that is, in this embodiment, the analysis is performed according to the ambient temperature of the non-fault area, and the start-stop control temperature representing the ambient temperature of the fault area is obtained to perform further air supply control operation.

In another embodiment, when the air valve controller 20 accesses the area control terminal 10, the area control terminal 10 may send only the preset temperature corresponding to the fault area to the air valve controller 20 to perform the air supply control of the fault area.
