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.
And S100, when an adjusting area required for opening the air valve exists, acquiring the total length of the air pipe of the adjusting area.
Specifically, the total length of the air ducts is the sum of the lengths of the air ducts. The adjusting area with the requirement of opening the air valve is the area which needs to open the air valve to supply air and realize the temperature adjusting operation. In a zone control system of the type of one-to-one air pipe unit, air pipes are arranged between the air pipe unit and each zone to convey cold air or hot air, air valves are correspondingly arranged on different air pipes, and independent refrigerating or heating operation of each zone can be realized by controlling the opening degree of the air valves. 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.
When the regulation area to the fan valve opening demand refrigerates or heats, the length of tuber pipe will directly influence the air output in each region, and under the certain circumstances of windscreen or wind speed of tuber pipe unit, tuber pipe length is longer, and the unit static pressure of tuber pipe unit will be big more, and the air output that corresponds will reduce. In the same area control system, if the air supply of the air pipe unit is not well matched with the length of the air pipe, the air quantity of some areas is too large or the air quantity of some areas is too small. Therefore, in the application, the corresponding air supply adjustment is carried out according to the air pipes corresponding to the areas where the air valves are opened to carry out temperature adjustment, so that the condition that the air supply is not constant is avoided.
It should be noted that in one embodiment, the damper controller may perform monitoring of whether there is a regulation region of the damper opening requirement, so that when there is a regulation region of the damper opening requirement, a corresponding control operation can be performed in time. The specific monitoring mode is not exclusive, for example, in one embodiment, the air valve controller may detect whether an opening command for opening the air valve is received from a user, and when the opening command is received, the air valve controller indicates that there is a regulation region for opening the air valve. It will be appreciated that when there is no adjustment zone for the demand to open the damper, the damper controller will not have to obtain the total length of the duct, and will continue to operate whether there is an adjustment zone for the demand to open the damper.
And step S200, obtaining the static pressure of the air pipe unit required in the current state according to the total length of the air pipe.
Specifically, the size of the air pipe unit static pressure is directly linked with the length of the air pipe, and after the air valve controller obtains the total length of the air pipe of each air pipe corresponding to the adjusting area, the total length of the air pipe is analyzed, so that the air pipe unit static pressure optimally matched with users in the adjusting area of the current quantity and type is obtained.
And step S300, analyzing according to the static pressure of the air pipe unit and the corresponding preset static pressure to obtain a static pressure change value, and sending the static pressure change value to the air pipe unit.
Specifically, the static pressure change value is used for air supply adjustment of the air duct unit so as to realize constant air volume air supply of an adjustment area. The preset static pressure is the static pressure of the air pipe unit corresponding to the optimal air supply of each area when the air pipe unit supplies air in the adjusting area with the current air valve opening requirement. In the regional control system, because the distance from each air pipe unit to different regions and the adjusting region required for opening the air valve are all inconsistent, corresponding preset static pressures can be different for different regional combinations. Therefore, after the air valve controller obtains the static pressure of the air pipe unit according to the total length of the air pipe, the preset static pressure corresponding to the current adjusting area combination is obtained according to the adjusting area, and therefore the corresponding static pressure change value analysis operation is carried out.
It should be noted that in one embodiment, the preset static pressure is set by the user at the regional control terminal, and when the preset static pressure is needed for analysis, the preset static pressure is directly obtained from the regional control terminal. Namely, when the adjusting area with the requirement of opening the air valve exists, the air valve controller can access the area control terminal and obtain the preset static pressure corresponding to the area with the requirement of opening the air valve.
Further, in an embodiment, the static pressure variation value is a difference between the static pressure of the air duct unit and a preset static pressure, that is, when the air duct unit is analyzed according to the static pressure of the air duct unit and the corresponding preset static pressure, the static pressure of the air duct unit is directly subtracted from the preset static pressure, and the static pressure difference value is directly obtained and is the static pressure variation value. It is understood that in other embodiments, the static pressure variation value may also be embodied in other forms, for example, the static pressure variation value is a ratio between a static pressure difference value and a preset static pressure, as long as the static pressure variation value can be identified by the air duct unit and corresponding air supply adjustment can be performed.
And after the air pipe unit obtains the static pressure change value, carrying out corresponding adjustment operation according to the static pressure change value. For example, in one embodiment, if the static pressure of the air pipe unit obtained through analysis and calculation is greater than the preset static pressure, the corresponding static pressure change value is greater than 0, which indicates that the total length of the air pipe corresponding to the adjustment area is too long at the time, and if the air pipe unit supplies air with the current windshield or wind speed, the air flow will be too small. Therefore, at the moment, the air pipe unit can increase the air speed or heighten the windshield according to the static pressure change value sent by the air valve controller, so that the air volume reaching the adjusting area is kept consistent.
Referring to fig. 2, in one embodiment, step S100 includes step S110 and step S120.
And step S110, acquiring the air pipe length of the air pipe corresponding to each adjusting area.
Specifically, the technical solution of the present application is applicable to only one adjustment area or more than two adjustment areas, for facilitating understanding of the technical solution of the present application, the present embodiment and the subsequent embodiments are explained with more than two adjustment areas, and for the case of only one adjustment area, the air supply control may be performed by using a scheme consistent with more than two adjustment areas. In the actual operation process, the air valve controller can only directly obtain the air pipe length of one adjusting area, so that when a plurality of adjusting areas exist, the air valve controller can obtain the air pipe length of each adjusting area one by one so as to obtain the air pipe total length corresponding to the adjusting areas in the subsequent processing. For the case of only one adjustment area, the length of the primary air duct is only required to be acquired, that is, the length of the primary air duct can be taken as the total length of the air duct, and then the air supply adjustment operations in the subsequent steps S200 and S300 are performed.
And step S120, obtaining the total air duct length of the adjusting area according to the air duct lengths.
Specifically, after the air valve controllers acquire the air pipe lengths of the air pipes corresponding to the adjusting areas one by one when the adjusting areas exist, summation calculation is carried out according to the air pipe lengths of the air pipes to obtain the total air pipe length of the air pipes corresponding to the adjusting areas, and therefore subsequent air supply adjusting operation is carried out.
Referring to fig. 3, in one embodiment, step S110 includes step S111 and step S112.
Step S111 is to acquire a signal propagation loss when communicating with a temperature acquisition unit provided in the adjustment area.
Specifically, in the regional control system, in order to enable cold air or hot air delivered by the air valve to meet different user requirements and enable the temperature in different regions to reach the expected temperature of users, the air valve controller can receive temperature data collected by temperature collectors arranged in different regions in real time in a regional control scheme, so that the corresponding air valve is subjected to feedback adjustment. It should be noted that the number of temperature collectors in the same area is not unique, and one or more temperature collectors may be specifically set according to the size of the area and the user requirement. For example, in one embodiment, the temperature collectors and the air valves are arranged in a one-to-one correspondence manner, that is, one temperature collector is arranged in each zone of the zone control system for temperature collection, and one air valve is arranged for air supply control. Further, in one embodiment, each temperature collector 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.
In the area control system of one-driving-one air pipe unit, the linear distance between the air outlet valve controller and each adjusting area is directly reflected through the signal propagation loss when the air valve controller and the temperature collector are in wireless communication, and the air pipe lengths corresponding to different adjusting areas are represented through the linear distance. Therefore, when an adjusting area with the requirement for opening the air valve exists, the air valve controller communicates with the temperature collector corresponding to the adjusting area, and then the signal propagation loss of the communication signal in the transmission process is obtained, so that the length of the air pipe corresponding to the adjusting area is indirectly obtained according to the signal propagation loss.
And step S112, obtaining the air pipe length of the air pipe corresponding to each adjusting area according to each signal propagation loss.
Specifically, the signals may be attenuated to different degrees due to the distance of the transmission distance during the transmission process, so in this embodiment, the distance is calculated according to the attenuation degree of the signals, that is, the signal propagation loss, and then the calculated distance is used to represent the length of the air duct corresponding to the adjustment area.
It should be noted that, in an embodiment, for the same adjustment area, when the length of the air duct corresponding to the air duct is calculated according to the signal propagation loss, the specific calculation times are not unique, as long as a value representing the length of the air duct corresponding to the air duct in the area can be finally obtained. For example, in one embodiment, the air valve controller communicates with the temperature collectors in the same adjustment area for multiple times, each communication obtains a corresponding signal propagation loss according to the change condition of the communication signal, a length value of the air pipe can be obtained according to each signal propagation loss, and finally, the length values of the air pipes are averaged to obtain the final length of the air pipe. It is understood that in other embodiments, other processing manners may be used to process the length values of the air ducts, as long as a reasonable value representing the length of the air duct is obtained.
Further, in one embodiment, when the air valve controller calculates the length of the air pipe according to the signal propagation loss of multiple communications, the communication signal strengths of the communication signals sent to the temperature collector by the air valve controller each time are different from each other, that is, the length of the air pipe is calculated according to the signal propagation loss of the communication signals with different strengths, and then the analysis is performed according to multiple measurement results, so that a reasonable length of the air pipe is obtained finally. In other embodiments, signals with the same intensity may be used for communication, and then calculation is performed according to the signal propagation loss obtained by each communication, so as to obtain the length value of the air duct each time for processing.
Referring to fig. 4, in one embodiment, step S111 includes step S11, step S12, and step S13.
And step S11, sending detection signals to the temperature collectors corresponding to the adjusting areas, and recording the intensity of the detection signals.
Specifically, in this embodiment, taking the measurement of the length of the primary air duct as an example, the air valve controller is provided with a component for detecting and calculating the signal intensity, and after the air valve controller determines that there is an adjustment area where the air valve needs to be opened, the air valve controller will communicate with a temperature collector corresponding to one of the adjustment areas, and send a signal with an intensity of P1 to the temperature collector. It can be understood that when a plurality of adjusting areas exist, the air valve controller can simultaneously send signals with the signal intensity of P1 to the plurality of temperature collectors, and then analyze the signals respectively according to the signals returned by the temperature collectors, and finally obtain the air pipe lengths of the adjusting areas. In other embodiments, when there are multiple adjustment areas, the air valve controller may also call the temperature collector periodically with a signal strength P1, and then sequentially obtain the length of the air duct corresponding to each adjustment area.
And step S12, receiving the feedback signal returned by the temperature collector according to the detection signal and recording the intensity of the feedback signal.
Specifically, after the temperature collector receives the P1 signal sent by the air valve controller, a feedback signal is sent to the air valve controller, and the air valve controller records the signal strength S1 of the feedback signal. It can be understood that, in the scheme that the air valve controller and the air pipe controller further analyze the results of multiple measurements to obtain a reasonable air pipe length, after the air valve controller records the signals returned by the temperature collector, the temperature collector is periodically called by taking P2, P3 and the like as transmitting power, the temperature collector can reply data signals to the air valve controller, the air valve controller receives the received data signals, records the signal strengths S2, S3 and the like of the time, and then performs subsequent air pipe length calculation operation.
And step S13, obtaining the signal propagation loss corresponding to the adjusting area according to the detection signal strength and the feedback signal strength.
Specifically, after the air valve controller receives the feedback signal, the final signal propagation loss is obtained according to the difference between the signal strength of the transmission signal and the signal strength of the feedback signal. It should be noted that, for the different number of adjustment regions and the condition that the number of times of measuring the length of the air duct in each adjustment region is not unique, the method similar to the present embodiment is adopted to obtain the corresponding signal propagation loss, and then the final length of the air duct is obtained according to the signal propagation loss.
Referring to FIG. 4, in one embodiment, step S112 includes step S21.
And step S21, calculating the air pipe length of the air pipe corresponding to each adjusting area according to the signal propagation loss and the working frequency when the temperature collector is communicated.
Specifically, the component for sending and receiving signals in the air valve controller to obtain the corresponding signal strength has a certain working frequency during working, and the working frequency can be intuitively obtained according to the performance parameters of the component. Therefore, in this embodiment, the air duct length of the air duct corresponding to the adjustment area is obtained by performing analysis and calculation according to the signal propagation loss, the operating frequency, and the like.
Further, in one embodiment, the length of the duct is calculated by: and S is 32.44+20lg H +20lgZ, wherein S is signal propagation loss and is expressed in dB, H is the distance between the air valve controller and the temperature collector and is used for representing the length of the air pipe of the adjusting area corresponding to the temperature collector, and is expressed in km, and Z is the working frequency of a signal transmitting and receiving component in the air valve controller and is expressed in MHz.
It is to be understood that it is not unique how the duct pack static pressure is obtained, particularly based on the total duct length, and referring to fig. 5, in one embodiment, step S200 includes step S210.
And step S210, calculating according to the total length of the air pipe and a preset static pressure value to obtain the static pressure of the air pipe unit required in the current state.
Specifically, the preset static pressure value is the static pressure variation of the air pipe unit corresponding to the air pipe of the unit length. It can be understood that, in an embodiment, the preset static pressure value is preset in the regional control terminal, and when the air valve controller needs to calculate the static pressure value of the air duct unit according to the preset static pressure value, the air valve controller will access the regional control terminal, so as to obtain the corresponding preset static pressure value for analysis and calculation. It should be noted that the preset static pressure value may specifically be a static pressure variation of the air duct unit corresponding to each meter of the air duct, or may also be a static pressure variation of the air duct unit corresponding to each decimeter of the air duct, and may specifically be set by a user according to an actual situation.
Further, in one embodiment, the static pressure of the air duct unit is calculated by: and P is the preset static pressure value, P is the static pressure of the air pipe unit, L represents the total length of the air pipe corresponding to the adjusting area required by opening the air valve, and multiplied by the value.
According to the area control method, when the adjusting areas with the air valve opening requirements exist, the air valve controller can obtain the total length of the air pipes corresponding to each adjusting area at the moment, and the static pressure of the air pipe unit required when the areas with the current number supply air simultaneously is obtained according to the total length of the air pipes. And then analyzing according to the static pressure of the air pipe unit and the corresponding preset static pressure to obtain a static pressure change value, and sending the static pressure change value to the air pipe unit so that the air pipe unit can conveniently perform air supply adjustment according to the static pressure change value, and correcting the air supply quantity of the air pipe unit at the moment to realize constant air supply operation for users. Through the scheme, when the area needing to open the air valve to supply air changes in the area control system of one-drag air pipe unit type or the air pipe of the air pipe unit supplying air changes, the air valve controller can analyze the air pipe according to the total length of the air pipe, so that the air pipe unit can supply air in real time and adjust the air. The air supply quantity of each area is constant, the situation that the air supply quantity is increased or reduced due to the fact that the air pipe used for supplying air by the air pipe unit is changed is avoided, and the air supply control system has the advantage of being high in control reliability.
