The invention provides a method for determining the number of an air conditioner indoor unit. The air conditioner comprises at least two internal machines, and the at least two internal machines are connected with different control ports of a controller of the air conditioner.
Specifically, the air conditioner comprises an outer machine and at least two inner machines, the outer machine is matched with the at least two inner machines through a controller, the controller is provided with at least two control ports, and the at least two inner machines are respectively connected with different control ports of the controller. Under the condition that a display terminal is not available, users and engineering personnel cannot know the number of each internal machine and cannot determine the control port of each internal machine corresponding to one dragging more controllers.
For example, fig. 2 is a schematic diagram of a multi-split air conditioning control system according to an embodiment of the invention. Referring to fig. 2, an outdoor unit is matched with four indoor units, namely a first indoor unit, a second indoor unit, a third indoor unit and a fourth indoor unit, through a multi-split controller.
Fig. 1 is a schematic method diagram of an embodiment of a method for determining an air conditioner internal unit number according to the present invention. As shown in fig. 1, according to an embodiment of the present invention, the method for determining the number of the air conditioner indoor unit includes at least step S110 and step S120.
And step S110, sending air supply instructions for supplying air with different wind gears to the at least two internal machines through the different control ports so as to control the at least two internal machines to supply air according to the corresponding wind gears.
Specifically, the controller is controlled to send air supply instructions for supplying air to the connected internal machines through the different control ports by using the wind shelves corresponding to the corresponding port numbers. More specifically, different ports to which the at least two internal machines are connected correspond to different wind gears, for example, the air conditioner includes four internal machines, the connected control ports are respectively port 1, port 2, port 3, and port 4, that is, the port numbers are respectively 1, 2, 3, and 4, and then the different wind gears corresponding to port 1, port 2, port 3, and port 4 can be respectively set as a first wind gear, a second wind gear, a third wind gear, and a fourth wind gear. The rotating speeds of the fans corresponding to the first wind gear, the second wind gear, the third wind gear and the fourth wind gear are different, for example, referring to table 1, the rotating speed of the fan corresponding to the first wind gear is 0-100 r/min, the rotating speed of the fan corresponding to the second wind gear is 300-400 r/min, the rotating speed of the fan corresponding to the third wind gear is 600-700 r/min, and the rotating speed of the fan corresponding to the fourth wind gear is 900-1000 r/min.

TABLE 1
If the number of the internal machines is small, the corresponding wind sensation grade with large difference can be sent, and the corresponding internal machine number can be determined by engineering personnel directly through human body sensory judgment. For example, only 2 internal machines are online, a first wind sensing instruction is sent through the port 1, so that the first internal machine operates a first wind gear, and a fourth wind sensing instruction is sent through the port 2, so that the second internal machine operates a fourth wind gear.
And step S120, detecting the air supply speeds of the at least two internal machines, and determining the control ports respectively connected with the at least two internal machines according to the air supply speeds, so as to determine the numbers of the at least two internal machines.
Specifically, the wind gear for supplying air by the at least two internal machines is respectively determined according to the air supply wind speeds of the at least two internal machines; and determining control ports connected with the at least two internal machines respectively according to the determined wind gear for supplying air by the at least two internal machines. Alternatively, the supply air speed of the at least two internal machines may be detected by a velocimeter.
Presetting different wind gears corresponding to the control ports connected with the at least two internal machines, and presetting the rotating speeds of fans corresponding to the different wind gears. For example, for an air conditioner including four internal machines, four wind gear levels with different fan rotation speeds may be preset, for example, the fan rotation speeds corresponding to the four wind gears are different from high to low. Further, the corresponding air supply speed when air is supplied according to different wind gears is predetermined, so that the wind gears for supplying air by the at least two internal machines can be determined according to the detected air supply speeds of the at least two internal machines. For example, the range of the air supply speed when the internal machine supplies air at different wind gears (according to the preset fan rotating speeds corresponding to different wind gears) is measured in advance. Optionally, different air supply speed ranges are set to different wind sensation levels, the air speed ranges of the air supply speed when the indoor unit supplies air at different wind gears (according to the preset fan rotating speeds corresponding to the different wind gears) are measured in advance, and the air supply speed ranges when the indoor unit supplies air at different wind gears are set to different wind sensation levels respectively, so that the corresponding relation between the different wind sensation levels and the different wind gear levels is obtained.
For example, referring to table 1, for an air conditioner including four internal machines, wind gear levels with different fan rotation speeds may be preset, which are a first wind gear, a second wind gear, a third wind gear and a fourth wind gear, respectively, and an air supply wind speed range corresponding to four wind sense levels corresponding to the four wind gear levels is obtained, which are a first wind sense, a second wind sense, a third wind sense and a fourth wind sense, respectively, after detecting the air supply wind speeds of the at least two internal machines by a velocimeter, the corresponding wind gear levels are determined according to the determined wind sense levels, that is, the wind gears for supplying air to the internal machines, and then control ports connected to the internal machines are determined according to the determined wind gears, thereby determining the serial numbers of the internal machines. Optionally, the internal unit numbers correspond to the port numbers of the control ports one to one, for example, as shown in table 1, a first internal unit corresponds to the port 1, a second internal unit corresponds to the port 2, a third internal unit corresponds to the port 3, and a fourth internal unit corresponds to the port 4. Optionally, the wind sensation level may be directly corresponding to the port number of the control port, and the corresponding control port may be directly determined according to the detected wind sensation level, so as to determine the internal unit number.
Optionally, before sending an air supply instruction for supplying air with different wind gears to the at least two internal machines through the different control ports, receiving an instruction for detecting an internal machine number sent by a control terminal, and when receiving the instruction for detecting the internal machine number, executing the step S110 and the step S120, that is, when receiving the instruction for detecting the internal machine number, sending an air supply instruction for supplying air with different wind gears to the at least two internal machines through the different control ports, so as to control the at least two internal machines to supply air according to the corresponding wind gears; and determining the control ports respectively connected with the at least two internal machines according to the air supply speed by detecting the air supply speed of the at least two internal machines, thereby determining the serial numbers of the at least two internal machines. Further, after controlling the at least two internal machines to supply air according to corresponding wind gears, receiving an instruction of detecting the number of the internal machine quitting sent by the control terminal; and when an instruction for exiting the internal machine number detection is received, the controller sends an operation state recovery instruction to the at least two internal machines to enable the at least two internal machines to recover to the operation state before the air supply instruction is received.
For example, when a user or an engineer needs to determine the internal machine numbers corresponding to internal machines installed in different areas, the internal machine number detection function can be started through a control terminal (for example, a wire controller, a remote controller, a mobile terminal installed with an APP, and the like), the control terminal sends an internal machine number detection instruction to a controller of an air conditioner, so as to trigger a control logic for detecting the internal machine numbers of the air conditioner, and after receiving the internal machine number detection instruction, the controller sends air supply instructions for supplying air with different wind gears to the at least two internal machines through different control ports. After the internal machine numbers of the internal machines are determined, a user or an engineer exits the internal machine number detection function through the control terminal, the control terminal sends an internal machine number exiting detection instruction to a controller of the air conditioner, the controller sends an operation state recovery instruction to the at least two internal machines after receiving the internal machine number exiting detection instruction, and the at least two internal machines recover to the operation state before receiving the air supply instruction. Optionally, the at least two internal machines record an operation state before receiving the air supply instruction when receiving the air supply instruction sent by the controller, and recover to the operation state before receiving the air supply instruction when receiving an operation state recovery instruction.
In order to clearly illustrate the technical solution of the present invention, an execution flow of the method for determining the number of the air conditioner internal unit according to the present invention is described below with a specific embodiment.
Fig. 3 is a schematic method diagram of an embodiment of a method for determining an air conditioner internal unit number according to the present invention. As shown in fig. 3, when the air conditioning unit normally operates, whether an indoor unit number detection instruction is received or not is judged, if the indoor unit number detection instruction is received, an indoor unit number detection logic is triggered, air supply instructions for supplying air according to different wind gears are sent to the indoor units through different control ports, namely, the nth indoor unit is controlled to operate at the nth gear rotating speed through the corresponding control ports, the indoor unit numbers of the indoor units are determined by detecting the air supply speeds of the indoor units, and after the indoor unit numbers are determined, the unit exits from the indoor unit number detection logic and continues to operate according to the previous logic.
The invention also provides a device for determining the number of the air conditioner indoor unit. The air conditioner comprises at least two internal machines, and the at least two internal machines are connected with different control ports of a controller of the air conditioner. Specifically, the air conditioner comprises an outer machine and at least two inner machines, the outer machine is matched with the at least two inner machines through a controller, the controller is provided with at least two control ports, and the at least two inner machines are respectively connected with different control ports of the controller. Under the condition that a display terminal is not available, users and engineering personnel cannot know the number of each internal machine and cannot determine the control port of each internal machine corresponding to one dragging more controllers. For example, fig. 2 is a schematic diagram of a multi-split air conditioning control system according to an embodiment of the invention. Referring to fig. 2, an outdoor unit is matched with four indoor units, namely a first indoor unit, a second indoor unit, a third indoor unit and a fourth indoor unit, through a multi-split controller.
Fig. 4 is a block diagram of an embodiment of an air conditioner internal unit number determining device according to the present invention. As shown in fig. 4, the air conditioner internal unit number determination device 100 includes a transmission unit 110 and a determination unit 120.
The sending unit 110 is configured to send an air supply instruction for supplying air with different wind gears to the at least two internal machines through the different control ports, so as to control the at least two internal machines to supply air according to the corresponding wind gears.
Specifically, the controller is controlled to send air supply instructions for supplying air to the connected internal machines through the different control ports by using the wind shelves corresponding to the corresponding port numbers. More specifically, different ports to which the at least two internal machines are connected correspond to different wind gears, for example, the air conditioner includes four internal machines, the connected control ports are respectively port 1, port 2, port 3, and port 4, that is, the port numbers are respectively 1, 2, 3, and 4, and then the different wind gears corresponding to port 1, port 2, port 3, and port 4 can be respectively set as a first wind gear, a second wind gear, a third wind gear, and a fourth wind gear. The rotating speeds of the fans corresponding to the first wind gear, the second wind gear, the third wind gear and the fourth wind gear are different, for example, referring to table 1, the rotating speed of the fan corresponding to the first wind gear is 0-100 r/min, the rotating speed of the fan corresponding to the second wind gear is 300-400 r/min, the rotating speed of the fan corresponding to the third wind gear is 600-700 r/min, and the rotating speed of the fan corresponding to the fourth wind gear is 900-1000 r/min.

| 2 | Port 2 | Second wind sensation | Second windshield | 300～400 |
| 3 | Port 3 | Third wind sensation | Third windshield | 600～700 |
| 4 | Port 4 | The fourth wind sensation | Fourth windshield | 900～1000 |

Further, the corresponding air supply speed when air is supplied according to different wind gears is predetermined, so that the wind gears for supplying air by the at least two internal machines can be determined according to the detected air supply speeds of the at least two internal machines. For example, the range of the air supply speed when the internal machine supplies air at different wind gears (according to the preset fan rotating speeds corresponding to different wind gears) is measured in advance. Optionally, different air supply speed ranges are set to different wind sensation levels, the air speed ranges of the air supply speed when the indoor unit supplies air at different wind gears (according to the preset fan rotating speeds corresponding to the different wind gears) are measured in advance, and the air supply speed ranges when the indoor unit supplies air at different wind gears are set to different wind sensation levels respectively, so that the corresponding relation between the different wind sensation levels and the different wind gear levels is obtained.
For example, referring to table 1, for an air conditioner including four internal machines, wind gear levels with different fan rotation speeds may be preset, which are a first wind gear, a second wind gear, a third wind gear and a fourth wind gear, respectively, and an air supply wind speed range corresponding to four wind sense levels corresponding to the four wind gear levels is obtained, which are a first wind sense, a second wind sense, a third wind sense and a fourth wind sense, respectively, after detecting the air supply wind speeds of the at least two internal machines by a velocimeter, the corresponding wind gear levels are determined according to the determined wind sense levels, that is, the wind gears for supplying air to the internal machines, and then control ports connected to the internal machines are determined according to the determined wind gears, thereby determining the serial numbers of the internal machines.
