Description

Technical Field

[0001] The present invention relates to the technical field of fresh air systems, and in particular, to a binding control method, an operation control device, and a fresh air system for a fresh air system. Background Art

[0002] Currently, in some large-sized residential buildings, there are application scenarios where multiple fresh air machines are linked to multiple indoor machines in rooms for air quality control. After the indoor machines in the rooms are bound and paired with the fresh air machines, in a normal controllable scenario, if there is a one-to-many or many-to-one relationship between the fresh air machines and the rooms, conflicts may occur during use.

[0003] In the prior art, for the existing conflict situations, generally only a prompt indicating a binding conflict is reported, and the operator needs to go to the room associated with the binding conflict to operate the indoor machine to check for conflicts, and unbind the existing binding conflicts one by one until the fault disappears, which consumes a lot of time and energy of the operator; moreover, after unbinding, other fresh air machines need to be bound to meet the air treatment requirements of the room, and during the process of re-binding, there may still be problems of re-binding conflicts. In addition, there may be multiple people in the fresh air system who simultaneously operate to bind the indoor machine and the fresh air machine, resulting in a more likely occurrence of binding conflicts and more complex binding conflict situations, which are not easy to check and eliminate. Summary of the Invention

[0004] An object of the present invention is to at least solve one of the technical problems existing in the prior art, and provide a binding control method, an operation control device, and a fresh air system for a fresh air system, which can perform error correction processing on possible conflict situations, greatly improving the efficiency of adding new binding relationships and reducing the time and energy for troubleshooting.

[0005] In a first aspect, an embodiment of the present invention provides a binding control method for a fresh air system, where the fresh air system includes multiple fresh air machines and multiple indoor machines communicatively connected through a bus; the method includes:

[0006] When it is detected that a first indoor machine among the multiple indoor machines and a first fresh air machine among the multiple fresh air machines add a new binding relationship, mark the first indoor machine as the first state, and determine whether a preset conflict condition is satisfied; during the existence of the first state, prohibit the fresh air system from adding new binding relationships;

[0007] When the preset conflict condition is satisfied, revoke the binding relationship between the first indoor machine and the first fresh air machine; when the preset conflict condition is not satisfied, determine that the binding between the first indoor machine and the first fresh air machine is successful;

[0008] Wherein, the preset conflict condition is: at least two fresh air machines are bound to the same indoor machine and any one of the at least two fresh air machines is also bound to another indoor machine.

[0009] According to the binding control method of the fresh air system provided by the embodiments of the present invention, it has at least the following beneficial effects: when a new binding relationship between the first indoor unit and the first fresh air unit is detected, the first indoor unit is marked as the first state, thereby prohibiting the fresh air system from adding other binding relationships. That is, without determining whether the newly added binding relationship will cause a binding conflict, adding other binding relationships is not allowed, avoiding the situation where the newly added binding relationship and other newly added binding relationships simultaneously cause binding conflicts, resulting in a more complex binding conflict situation in the entire fresh air system; while marking the first indoor unit, it is judged whether the fresh air system meets the preset conflict condition, and the preset conflict condition is set as at least two fresh air units are bound to the same indoor unit and any one of the at least two fresh air units is also bound to another indoor unit. When this preset conflict condition is met, it is possible that another indoor unit controls one of the fresh air units to operate an air treatment function different from the previous one, resulting in the two fresh air units treating the air in the same room with different air treatment functions. Therefore, canceling the binding relationship between the first indoor unit and the first fresh air unit after meeting this condition can avoid this conflict situation. After the cancellation is successful, the user can perform other bindings to meet the air treatment requirements of the room; after it is confirmed that the newly added binding relationship does not meet the preset conflict condition, it is determined that the newly added binding relationship between the first indoor unit and the first fresh air unit is successfully established and will not cause a conflict situation; the binding control method of this fresh air system can correct possible conflict situations, greatly improving the efficiency of adding binding relationships and reducing the time and effort for troubleshooting.

[0010] According to the binding control method of the fresh air system provided by some embodiments of the present invention, when the preset conflict condition is not met, the first state is cleared; or, when the binding relationship between the first indoor unit and the first fresh air unit is successfully cancelled, the first state is cleared.

[0011] According to the binding control method of the fresh air system provided by some embodiments of the present invention, the situations that meet the preset conflict condition include:

[0012] The first indoor unit has been bound to a second fresh air unit, and the second fresh air unit has also been bound to a second indoor unit;

[0013] The second fresh air unit is one of the multiple fresh air units, and the second indoor unit is one of the multiple indoor units.

[0014] According to the binding control method of the fresh air system provided by some embodiments of the present invention, it further includes: determining that the first indoor unit is a conflict indoor unit, and determining that the first fresh air unit is a conflict fresh air unit.

[0015] According to the binding control method of the fresh air system provided by some embodiments of the present invention, the situations that meet the preset conflict condition include:

[0016] The first fresh air unit has been bound to a third indoor unit, and the third indoor unit has also been bound to a third fresh air unit;

[0017] The third fresh air unit is one of the multiple fresh air units, and the third indoor unit is one of the multiple indoor units.

[0018] The binding control method for the fresh air system provided by some embodiments of the present invention further includes: determining that the third indoor unit is a conflicting indoor unit and determining that the first fresh air unit is a conflicting fresh air unit.

[0019] The situations that satisfy the preset conflict conditions in the binding control method for the fresh air system provided by some embodiments of the present invention include:

[0020] The first indoor unit has been bound to a fourth fresh air unit, and the first fresh air unit has been bound to a fourth indoor unit;

[0021] The fourth fresh air unit is one of the multiple fresh air units, and the fourth indoor unit is one of the multiple indoor units.

[0022] The binding control method for the fresh air system provided by some embodiments of the present invention determines that the first indoor unit is a conflicting indoor unit and determines that the first fresh air unit is a conflicting fresh air unit.

[0023] The binding control method for the fresh air system provided by some embodiments of the present invention further includes, during the existence period of the first state:

[0024] Mark the conflicting indoor unit and the conflicting fresh air unit as in a conflict failure state and issue a conflict failure flag;

[0025] Close the refrigeration manifold for the room where the conflicting indoor unit is located and prohibit the start of the refrigeration function; control the conflicting fresh air unit to be forced to standby.

[0026] The binding control method for the fresh air system provided by some embodiments of the present invention re-judges whether the preset conflict conditions are satisfied every first preset time period;

[0027] When the existence duration of the first state or the conflict failure state is greater than a second preset time period, issue a binding revocation impossible flag, and the second preset time period is greater than the first preset time period.

[0028] In a second aspect, an embodiment of the present invention provides an operation control device, including a memory, a processor, and a computer program stored on the memory and executable on the processor, and the processor executes the program to implement the binding control method for the fresh air system as described in the first aspect.

[0029] In a third aspect, an embodiment of the present invention provides a fresh air system, including the operation control device described in the second aspect.

[0042] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The function of the accompanying drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention. However, it should not be construed as a limitation on the protection scope of the present invention.

[0043] In the description of the embodiments of the present invention, the meaning of "several" is one or more, the meaning of "multiple" is more than two, understandings such as "greater than", "less than", "exceeding", etc. do not include the number itself, understandings such as "above", "below", "within", etc. include the number itself, "at least one" means one or more, and "at least one of the following" and its similar expressions refer to any combination of these items, including any combination of single items or plural items. If there is a description of "first", "second", etc., it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0044] It should be noted that words such as "set", "installed", "connected", etc. in the embodiments of the present invention should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the embodiments of the present invention in combination with the specific content of the technical solution. For example, the term "connected" can be a mechanical connection, an electrical connection, or can communicate with each other; it can be directly connected or indirectly connected through an intermediate medium.

[0045] It should be noted that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0046] Currently, in some large-sized apartment buildings, there is an application scenario where multiple fresh air units are linked to multiple indoor units in rooms for air quality control. After the indoor units in the rooms are bound and paired with the fresh air units, in the normal controllable scenario, if there is a one-to-many or many-to-one relationship between the fresh air unit and the room, it may lead to conflict situations during use.

[0047] In the prior art, for the existing conflict situations, generally only a prompt indicating the existence of a binding conflict is reported. The operator needs to go to the room associated with the binding conflict to operate the indoor unit in the room to check for conflicts, and unbind the existing binding conflicts one by one until the fault disappears, resulting in a large amount of time and energy consumption for the operator; moreover, after unbinding, other fresh air units need to be bound to meet the air treatment requirements of the room, and during the process of re-binding, there may still be problems of re-binding conflicts. In addition, in the fresh air system, there may also be operations where multiple people simultaneously bind the indoor unit and the fresh air unit, resulting in a more likely occurrence of binding conflicts and more complex binding conflict situations, which are not easy to check and eliminate.

[0048] Based on this, the embodiments of the present invention provide a binding control method, an operation control device and a fresh air system for a fresh air system, which can correct error handling for possible conflict situations, greatly improving the efficiency of adding new binding relationships and reducing the time and energy for troubleshooting.

[0049] The following further elaborates on the embodiments of the present invention in conjunction with the accompanying drawings.

[0050] Refer to Figure 1 , Figure 1 which is a bus connection relationship diagram between a fresh air machine and an indoor unit on the fresh air system provided by the embodiments of the present invention. The fresh air system includes multiple fresh air machines and multiple indoor units that are communicatively connected via a bus. Refer to Figure 2 , Figure 2 which is a flowchart of the binding control method for the fresh air system provided by the embodiments of the present invention. The method includes but is not limited to steps S110 to S140:

[0051] Step S110: When it is detected that a new binding relationship is added between a first indoor unit among multiple indoor units and a first fresh air machine among multiple fresh air machines, mark the first indoor unit as the first state and determine whether a preset conflict condition is met;

[0052] It should be noted that after the fresh air machine and the indoor unit in the system complete the binding relationship, they will be in a data polling and monitoring state with each other. Multiple indoor units query whether there is a new fresh air machine added to their own binding sequence. Further, when it is detected that a new binding relationship is added between a first indoor unit among multiple indoor units and a first fresh air machine among multiple fresh air machines, mark the first indoor unit as the first state.

[0053] It should be noted that the first state can be displayed in the system using a specific color. Preferably, the indoor unit marked as the first state can be displayed in the system as blue.

[0054] Step S120: During the duration of the first state, prohibit the fresh air system from adding new binding relationships;

[0055] It can be understood that the first state will last until the system confirms that the conflict has been resolved or the preset conflict condition is not met. During the duration of the first state, the conflict may not have been resolved yet. At this time, if a new binding relationship is added, it will increase the burden on the system to handle the conflict that occurred in the previous added binding relationship. At this time, prohibiting the fresh air system from adding new binding relationships can avoid further mutual exclusion problems and is beneficial to shortening the time for the system to solve problems.

[0056] Step S130: When the preset conflict condition is met, revoke the binding relationship between the first indoor unit and the first fresh air machine;

[0057] It should be noted that the preset conflict condition is as follows: at least two fresh air fans are bound to the same indoor unit, and any one of at least two fresh air fans is also bound to another indoor unit, and mutually exclusive functions occur between any two fresh air fans bound to the same indoor unit.

[0058] It can be understood that if there is at least one more fresh air fan bound to the same indoor unit as the first fresh air fan except the first fresh air fan, and the first fresh air fan and any one of the other fresh air fans are also bound to another indoor unit, it will cause the functions originally set for the fresh air fans bound to a certain indoor unit to change under normal circumstances. For example, the function originally set for the fresh air fan bound to a certain indoor unit is dehumidification. Due to the newly added binding relationship satisfying the preset condition, the original dehumidification function of the fresh air fan becomes a humidification function, resulting in control chaos.

[0059] Furthermore, in some embodiments, when the binding relationship between the first indoor unit and the first fresh air fan is successfully revoked, the first state is cleared. The system automatically revokes the binding relationship between the first indoor unit and the first fresh air fan, restores the originally set function settings of the fresh air fan, and then clears the first state, and the binding function of the fresh air system is restored again.

[0060] Step S140: When the preset conflict condition is not satisfied, it is determined that the binding between the first indoor unit and the first fresh air fan is successful.

[0061] According to the binding control method of the fresh air system provided by the embodiments of the present invention, when a new binding relationship between the first indoor unit and the first fresh air fan is detected, the first indoor unit is marked as the first state, thereby prohibiting the fresh air system from adding other binding relationships. That is, without determining whether the newly added binding relationship will cause a binding conflict, other binding relationships are not allowed to be added, avoiding the situation where the newly added binding relationship and other newly added binding relationships cause binding conflicts at the same time, resulting in a more complex binding conflict situation in the entire fresh air system; while marking the first indoor unit, it is judged whether the fresh air system satisfies the preset conflict condition. The preset conflict condition is set as at least two fresh air fans are bound to the same indoor unit and any one of at least two fresh air fans is also bound to another indoor unit. When this preset conflict condition is satisfied, it is possible that another indoor unit controls one of the fresh air fans to operate an air treatment function different from the previous one, resulting in two fresh air fans treating the air in the same room with different air treatment functions. Therefore, revoking the binding relationship between the first indoor unit and the first fresh air fan after this condition is satisfied can avoid this conflict situation. After the revocation is successful, the user can perform other bindings to meet the air treatment requirements of the room; after it is confirmed that the newly added binding relationship does not satisfy the preset conflict condition, it is determined that the newly added binding relationship between the first indoor unit and the first fresh air fan is successfully established and will not cause a conflict situation; this binding control method of the fresh air system can correct error processing for possible conflict situations, greatly improving the efficiency of adding binding relationships and reducing the time and energy for troubleshooting.

[0062] According to the binding control method of the fresh air system provided by some embodiments of the present invention, when the preset conflict condition is not satisfied, the first state is cleared.

[0063] It can be understood that when the newly added binding relationship is confirmed not to satisfy the preset conflict condition, the first state marked by the first indoor unit is cleared, so that the fresh air system allows other binding relationships to be newly added.

[0064] Refer to Figure 3 , Figure 3 is a system display diagram satisfying the preset conflict condition provided by an embodiment of the present invention. According to the binding control method of the fresh air system provided by some embodiments of the present invention, the situations satisfying the preset conflict condition include:

[0065] The first indoor unit is already bound to a second fresh air machine, and the second fresh air machine is also bound to a second indoor unit;

[0066] The second fresh air machine is one of multiple fresh air machines, and the second indoor unit is one of multiple indoor units.

[0067] It should be noted that the first indoor unit is bound to a first fresh air machine and a second fresh air machine, and the second fresh air machine is also bound to a second indoor unit. If the function set for the second fresh air machine is to dehumidify the rooms where the first indoor unit and the second indoor unit are located, and the function set for the first fresh air machine is to humidify, when the first indoor unit newly binds the first fresh air machine, there will be two conflicting function controls of humidification and dehumidification in the room where the first indoor unit is located, resulting in control errors and the inability to achieve correct control operations, reducing the user experience.

[0068] According to the binding control method of the fresh air system provided by some embodiments of the present invention, it further includes: determining that the first indoor unit is a conflicting indoor unit, and determining that the first fresh air machine is a conflicting fresh air machine.

[0069] It should be noted that if the function set for the second fresh air machine is to dehumidify the rooms where the first indoor unit and the second indoor unit are located, and the function set for the first fresh air machine is to humidify, when the first indoor unit newly binds the first fresh air machine, there will be two mutually conflicting function controls of humidification and dehumidification in the room where the first indoor unit is located, and the first indoor unit is determined to be a conflicting indoor unit.

[0070] It should be noted that since the first fresh air machine performs a humidification function in the room where the first indoor unit is located, and the second fresh air machine performs a dehumidification function in the room where the first indoor unit is located, the first fresh air machine newly bound by the first indoor unit performs a mutually exclusive function with the second fresh air machine originally bound to the first indoor unit, and the first fresh air machine is determined to be a conflicting fresh air machine.

[0071] Refer to Figure 4 , Figure 4It is another system display diagram provided by an embodiment of the present invention that meets the preset conflict conditions. According to the binding control method of the fresh air system provided by some embodiments of the present invention, the situations that meet the preset conflict conditions include:

[0072] The first fresh air machine has been bound to the third indoor unit, and the third indoor unit has also been bound to the third fresh air machine;

[0073] The third fresh air machine is one of multiple fresh air machines, and the third indoor unit is one of multiple indoor units.

[0074] It should be noted that the first indoor unit is bound to the first fresh air machine, and the third indoor unit is bound to the third fresh air machine and the first fresh air machine. If the functions set for the third fresh air machine and the first fresh air machine are to dehumidify the room where the third indoor unit is located, and the first indoor unit newly binds the first fresh air machine, if the room where the first indoor unit is located requires a humidifying function, then changing the original dehumidifying function of the first fresh air machine to a humidifying function at this time will result in two conflicting function controls of humidifying and dehumidifying in the room where the third indoor unit is located, which will cause control errors and the correct control operation cannot be achieved, reducing the user experience.

[0075] According to the binding control method of the fresh air system provided by some embodiments of the present invention, it further includes: determining that the third indoor unit is a conflict indoor unit, and determining that the first fresh air machine is a conflict fresh air machine.

[0076] It should be noted that the first indoor unit newly binds the first fresh air machine, changing the originally set dehumidifying function of the first fresh air machine to a humidifying function to meet the humidifying requirements of the room where the first indoor unit is located, while the function set for the third fresh air machine is to dehumidify the room where the third indoor unit is located. Since the third indoor unit is also bound to the first fresh air machine, there will be two conflicting function controls of humidifying and dehumidifying in the room where the third indoor unit is located at this time, and the third indoor unit is determined to be a conflict indoor unit.

[0077] It should be noted that since the third fresh air machine performs a dehumidifying function in the room where the first indoor unit is located, and the first fresh air machine performs a dehumidifying function in the rooms where the first indoor unit and the third indoor unit are located, at this time, the first fresh air machine newly bound by the first indoor unit performs a mutually exclusive function with the third fresh air machine originally bound by the third indoor unit, and the first fresh air machine is determined to be a conflict fresh air machine.

[0078] Refer to Figure 5 , Figure 5 It is another system display diagram provided by an embodiment of the present invention that meets the preset conflict conditions. According to the binding control method of the fresh air system provided by some embodiments of the present invention, the situations that meet the preset conflict conditions include:

[0079] The first indoor unit has been bound to the fourth fresh air machine, and the first fresh air machine has been bound to the fourth indoor unit;

[0080] The fourth fresh air unit is one of multiple fresh air units, and the fourth indoor unit is one of multiple indoor units.

[0081] It should be noted that the first indoor unit is bound to the first fresh air unit and the fourth fresh air unit, and the fourth indoor unit is bound to the first fresh air unit. If the function set for the first fresh air unit is to dehumidify the room where the fourth indoor unit is located, at this time, the first indoor unit newly binds the first fresh air unit. If the function set for the fourth fresh air unit is to humidify the room where the first indoor unit is located, then there will be two conflicting function controls of humidification and dehumidification in the room where the first indoor unit is located, resulting in control errors and unable to achieve correct control operations, reducing the user experience.

[0082] According to the binding control method of the fresh air system provided by some embodiments of the present invention, determine that the first indoor unit is a conflicting indoor unit and determine that the first fresh air unit is a conflicting fresh air unit.

[0083] It should be noted that the function set for the first fresh air unit originally bound to the fourth indoor unit is to dehumidify the room where the fourth indoor unit is located, and the function set for the fourth fresh air unit originally bound to the first indoor unit is to humidify the room where the first indoor unit is located. Since the first indoor unit is also bound to the first fresh air unit, there will be two conflicting function controls of humidification and dehumidification in the room where the first indoor unit is located, and the first indoor unit is determined to be a conflicting indoor unit.

[0084] It should be noted that since the first fresh air unit performs a dehumidification function in the rooms where the first indoor unit and the fourth indoor unit are located, and the fourth fresh air unit performs a humidification function in the room where the first indoor unit is located, at this time, the first fresh air unit newly bound to the first indoor unit performs a mutually exclusive function with the fourth fresh air unit originally bound to the first indoor unit, and the first fresh air unit is determined to be a conflicting fresh air unit.

[0085] Refer to Figure 6 , Figure 6 is the flowchart of the processing measures for meeting the preset conflict conditions provided by the embodiments of the present invention. According to the binding control method of the fresh air system provided by some embodiments of the present invention, during the existence period of the first state, it includes but is not limited to steps S210 - step S230:

[0086] Step S210: Mark the conflicting indoor unit and the conflicting fresh air unit as a conflict fault state and issue a conflict fault flag;

[0087] Refer to Figure 3 、 Figure 4 、 Figure 5 It should be noted that the conflict fault state can be marked by a specific color display. Both the conflicting indoor unit and the conflicting fresh air unit are marked as red. In this application, the conflict fault state is not overly limited.

[0088] Refer to Figure 3 、Figure 5 , further, if an indoor unit is marked as the first state and also marked as a conflicting indoor unit, then this indoor unit is marked as purple and displayed in the system.

[0089] It should be noted that the conflict fault flag can be displayed in the system in the form of a pop-up window, and in this application, there are no excessive limitations on the conflict fault flag.

[0090] It can be understood that after receiving the conflict fault flag, further processing is performed on the room where the conflicting indoor unit is located and the conflicting fresh air unit.

[0091] Step S220: Close the cooling distribution header of the room where the conflicting indoor unit is located and prohibit the start of the cooling function.

[0092] It can be understood that by closing the cooling distribution header of the room where the conflicting indoor unit is located and prohibiting the start of the cooling function, chaotic control between different devices can be avoided, ensuring the stable operation of the system. This helps to avoid energy waste and excessive wear of equipment, and improves the overall energy efficiency.

[0093] Furthermore, prohibiting the start of the cooling function can avoid the situation where condensation appears on the ceiling or floor of the room due to the failure of air temperature and humidity control, improving the user's trust and satisfaction with the system.

[0094] Step S230: Control the conflicting fresh air unit to be forced to standby.

[0095] It can be understood that after forcing the conflicting fresh air unit to standby, the room where the conflicting indoor unit is located is no longer affected by the mutually exclusive functions executed by the conflicting fresh air unit, realizing the automatic error correction processing of the bound conflict fault.

[0096] According to the binding control method of the fresh air system provided by some embodiments of the present invention, it is determined again whether the preset conflict condition is satisfied every first preset time period.

[0097] It should be noted that during the existence period of the first state, the system performs timing.

[0098] It can be understood that if the system realizes the automatic error correction processing of the bound conflict fault, when the first preset time period is reached, it will be detected that the preset conflict condition is no longer satisfied, the timing will be stopped, and the marks of the conflicting indoor unit, the conflicting fresh air unit, the indoor unit marked with the newly added bound fresh air unit in the first state, and the fault flag will be cleared. Preferably, the first preset time period is 1 min, and the first preset time period can be appropriately adjusted within the value range of 30 s to 2 min.

[0099] It can be understood that each time the first preset time period is reached, the number storing the first preset time period is cleared.

[0100] Further, if after reaching the first preset duration, it is detected that the preset conflict condition is still satisfied, it is determined whether the cumulative duration reaches the second preset duration. If the second preset duration is not reached, the automatic error correction process for the binding conflict fault continues, and the counting of the number stored for the first preset duration continues. When the first preset duration is reached again, if the system has implemented the automatic error correction process for the binding conflict fault, it is detected that the preset conflict condition is no longer satisfied, the timing is stopped, and the internal unit mark, conflict internal unit mark, conflict fresh air unit mark, and fault flag newly added to the first state are cleared.

[0101] It should be noted that the time required to determine whether the preset conflict condition is satisfied during the first state is much less than the first preset duration. When it is detected that the preset conflict condition is not satisfied, the timing is stopped and the first state is cleared.

[0102] When the survival duration of the first state or the conflict fault state, that is, the cumulative duration, is greater than the second preset duration, a binding cannot be revoked flag is issued, and the second preset duration is greater than the first preset duration.

[0103] It should be noted that during the existence of the first state, the time is cumulatively calculated. When the cumulative duration exceeds the second preset duration, a binding cannot be revoked flag is issued to notify the user for processing, and steps S220: closing the cooling manifold of the room where the conflict internal unit is located and prohibiting the start of the cooling function, and step S230: controlling the conflict fresh air unit to be forced to standby until the fault flag is revoked are continued. Preferably, the second preset duration is 10 min, and the second preset duration can be appropriately adjusted within the value range of 10 min to 30 min.

[0104] According to the binding control method of the fresh air system provided by some embodiments of the present invention, referring to Figure 7 , it includes steps S310 - S366:

[0105] Step S310: After the fresh air unit and the internal unit complete the binding relationship, they are in a data polling and monitoring state with each other;

[0106] Step S320: Multiple internal units query whether there is a newly added fresh air unit in their own binding sequence;

[0107] Step S330: When it is detected that a new binding relationship is added between the first internal unit among multiple internal units and the first fresh air unit among multiple fresh air units, the first internal unit is marked as the first state, and during the existence of the first state, the addition of a new binding relationship to the fresh air system is prohibited;

[0108] Step S340: Determine whether the preset conflict condition is satisfied;

[0109] Step S350: When the preset conflict condition is not met, clear the newly added binding of the first state to the indoor unit mark of the fresh air unit, the conflicting indoor unit mark, the conflicting fresh air unit mark, and the fault flag, and jump to step S310;

[0110] Step S361: When the preset conflict condition is met, revoke the binding relationship between the first indoor unit and the first fresh air unit;

[0111] Step S362: Mark the conflicting indoor unit and the conflicting fresh air unit as the conflict fault state and issue the conflict fault flag, close the cooling distribution header of the room where the conflicting indoor unit is located and prohibit the start of the cooling function, control the conflicting fresh air unit to be forced to standby, and start timing;

[0112] It should be noted that during the existence period of the first state, the system performs timing.

[0113] Step S363: Re-judge whether the preset conflict condition is met every first preset time period;

[0114] Step S364: If the preset conflict condition is not met, stop timing and jump to step S350;

[0115] Step S365: If the preset conflict condition is still met, judge whether the cumulative time exceeds the second preset time period. If it does not exceed the second preset time period, return to step S361;

[0116] Step S366: If it exceeds the second preset time period, issue a binding revocation failure flag and jump to step S362.

[0117] Next, in order to more clearly elaborate on the binding control method of the fresh air system of the present invention, a specific embodiment will be introduced in a comprehensive and detailed manner.

[0118] The fresh air system includes multiple fresh air units and multiple indoor units communicatively connected via a bus.

[0119] 1. First, after the fresh air unit and the indoor unit in the system complete the binding relationship, they will be in a data polling and monitoring state with each other, and multiple indoor units query whether there is a newly added fresh air unit in their own binding sequence.

[0120] 2. When it is detected that a new binding relationship is added between the first indoor unit among multiple indoor units and the first fresh air unit among multiple fresh air units, mark the first indoor unit as the first state, that is, display the first indoor unit as blue in the system, start timing, and judge whether the preset conflict condition is met;

[0121] 2.1. Judge whether the preset conflict condition is met: at least two fresh air units are bound to the same indoor unit and any one of at least two fresh air units is also bound to another indoor unit.

[0122] 3. During the existence period of the first state, prohibit the fresh air system from adding new binding relationships;

[0123] 4. When the preset conflict condition is met, the binding relationship between the first indoor unit and the first fresh air unit is revoked, and after the revocation is successful, the first status is cleared. 4.1 to 4.3 are three cases where the preset conflict condition is met concurrently and the corresponding handling measures;

[0124] 4.1. If the first indoor unit is already bound to a second fresh air unit, and the second fresh air unit is also bound to a second indoor unit, the second fresh air unit is one of multiple fresh air units, and the second indoor unit is one of multiple indoor units;

[0125] If the first fresh air unit connected to the first indoor unit and the second fresh air unit perform mutually exclusive functions in the room where the first indoor unit is located, determine that the first indoor unit is a conflict indoor unit and the first fresh air unit is a conflict fresh air unit, display the first fresh air unit in red in the system. Since the first indoor unit is both a conflict indoor unit and was previously marked and displayed in blue, at this time, the first indoor unit is displayed in purple in the system, indicating that it is both the indoor unit for the newly bound fresh air unit and a conflict indoor unit, and issue a conflict fault flag;

[0126] Close the cooling distribution header of the room where the first indoor unit is located and prohibit the start of the cooling function;

[0127] Control the first fresh air unit to force standby.

[0128] 4.2. If the first fresh air unit is already bound to a third indoor unit, and the third indoor unit is also bound to a third fresh air unit; the third fresh air unit is one of multiple fresh air units, and the third indoor unit is one of multiple indoor units;

[0129] If the third fresh air unit connected to the third indoor unit and the first fresh air unit perform mutually exclusive functions in the room where the third indoor unit is located, determine that the third indoor unit is a conflict indoor unit and the first fresh air unit is a conflict fresh air unit, display the first fresh air unit in red in the system, display the third indoor unit in red in the system, and issue a conflict fault flag;

[0130] Close the cooling distribution header of the room where the third indoor unit is located and prohibit the start of the cooling function;

[0131] Control the first fresh air unit to force standby.

[0132] 4.3. If the first indoor unit is already bound to a fourth fresh air unit, and the first fresh air unit is already bound to a fourth indoor unit; the fourth fresh air unit is one of multiple fresh air units, and the fourth indoor unit is one of multiple indoor units;

[0133] If the first fresh air unit connected to the first indoor unit and the fourth fresh air unit perform mutually exclusive functions in the room where the first indoor unit is located, determine that the first indoor unit is a conflicting indoor unit and the first fresh air unit is a conflicting fresh air unit. Display the first fresh air unit in red in the system. Since the first indoor unit is both a conflicting indoor unit and was previously marked and displayed in blue, at this time, the first indoor unit is displayed in purple in the system, indicating that it is both the indoor unit for newly added bound fresh air units and a conflicting indoor unit, and issue a conflict fault flag;

[0134] Close the cooling distribution header of the room where the first indoor unit is located and prohibit the start of the cooling function;

[0135] Control the first fresh air unit to be forced to standby.

[0136] It should be noted that during the existence period of the first state, the system performs timing.

[0137] 4.5. Re-judge whether the preset conflict condition is satisfied every first preset time period;

[0138] 4.51. If the system realizes automatic error correction processing for binding conflict faults, when the first preset time period is reached, stop timing, and clear the conflicting indoor unit mark, conflicting fresh air unit mark, the indoor unit mark of the newly added bound fresh air unit in the first state, and the fault flag.

[0139] 4.52. If the first preset time period is reached again, for example, after 1 minute, and it is detected that the preset conflict condition is still satisfied, if the cumulative time period does not exceed the second preset time period, continue with the automatic error correction processing for the binding conflict fault. When the first preset time period is reached again, if it is detected that the preset conflict condition is no longer satisfied, stop timing, and clear the indoor unit mark of the newly added bound fresh air unit in the first state, the conflicting indoor unit mark, the conflicting fresh air unit mark, and the fault flag.

[0140] 4.6. When the existence period of the first state or the conflict fault state, that is, the cumulative time period, is greater than the second preset time period, for example, 10 minutes, issue a binding cannot be revoked flag, notify the user for processing, and continue to keep the cooling distribution header of the room where the conflicting indoor unit is located closed and prohibit the start of the cooling function, and control the conflicting fresh air unit to be forced to standby until the fault flag is revoked.
