In the indoor controller 110 shown in fig. 1, the processor 111 may be configured to call a pairing status detection program stored in the memory 112, so as to implement the pairing status detection method.
Various embodiments of the air conditioner of the present invention are proposed based on the hardware structure of the indoor controller 110 described above.
As shown in fig. 2, fig. 2 is a schematic diagram illustrating a connection relationship between an indoor unit and an outdoor unit according to an embodiment of the present invention.
Specifically, the indoor unit 100 includes, but is not limited to, the indoor controller 110 shown in fig. 1 and the central coordinator module 120 connected to the indoor controller 110, and the outdoor unit 200 includes, but is not limited to, the outdoor controller 210 and the site module 220 and the load 230 connected to the outdoor controller 210, respectively. Wherein the central coordinator module 120 and the site module 220 are connected by a power line.
Next, as shown in fig. 2, the air conditioner according to the embodiment of the present invention further includes, but is not limited to, a sensor 300, and the sensor 300 may detect the operation state information of the load of the target outdoor unit and transmit the operation state information to the indoor unit 100. The target outdoor unit is one of the outdoor units 200, and the indoor unit 100 and the target outdoor unit are originally air-conditioning sets.
In addition, in order to enable the indoor unit 100 to reliably and stably acquire the operating state information through the sensor 300, the embodiment of the present invention may design the communication between the indoor unit 100 and the sensor 300 to be through non-power line communication, that is, through a communication line. For example, the indoor unit 100 and the sensor 300 may communicate with each other through RS 485.
Note that the load 230 may be a fan, a compressor, an expansion valve, a relay, a buzzer, or a lamp.
Based on the module hardware structure of the air conditioner in fig. 1 to 2, various embodiments of the pairing situation detection method of the present invention are proposed.
As shown in fig. 3, fig. 3 is a flowchart of a pairing status detection method according to an embodiment of the present invention.
The air conditioner provided by the embodiment of the invention comprises but is not limited to a target outdoor unit and an indoor unit, and a power line is arranged between the target outdoor unit and the indoor unit and is used for carrying out carrier communication between the target outdoor unit and the indoor unit, wherein the target outdoor unit and the indoor unit are originally air conditioner sets.
The pairing state detection method of the embodiment of the invention includes, but is not limited to, step S100 and step S200.
Step S100, sending pairing success information to the outdoor unit through the power line so that the outdoor unit drives a load of the outdoor unit according to the pairing success information;
and S200, acquiring running state information of the load of the target outdoor unit, and determining the pairing state between the indoor unit and the target outdoor unit according to the running state information.
Specifically, the indoor unit sends matching success information to the outdoor unit through the power line, then the outdoor unit receiving the matching success information drives the load of the indoor unit to operate, then the indoor unit obtains the operation state information of the load of the target outdoor unit, and then the indoor unit determines the matching condition between the target outdoor unit and the indoor unit according to the operation state information of the load of the target outdoor unit, wherein the target outdoor unit and the indoor unit are originally air-conditioning sets. According to the technical scheme of the embodiment of the invention, if the outdoor unit receiving the pairing success information is the target outdoor unit, the load of the target outdoor unit responds to the operation, and then the indoor unit acquires that the load of the target outdoor unit is in the operation state, so that the successful pairing between the target outdoor unit and the indoor unit can be determined; if the outdoor unit receiving the pairing success information is a non-target outdoor unit, that is, other outdoor units except the target outdoor unit, the load of the target outdoor unit does not respond to the operation, and the indoor unit acquires that the load of the target outdoor unit is in a non-operation state, so that it can be determined that the target outdoor unit and the indoor unit are not successfully paired. Therefore, the embodiment of the invention can detect the pairing condition between the indoor unit and the outdoor unit under the condition of not increasing a hardware signal isolator, thereby reducing the cost of the air conditioner and improving the competitiveness of the air conditioner product.
For example, when a user purchases an air conditioner and installs pairing at home, an indoor unit in the air conditioner of the user may send pairing success information to an external outdoor unit, and since the sending method is a broadcast method, the indoor unit cannot know whether the sent pairing success information is accurately sent to the outdoor unit of the air conditioner purchased by the user. If the outdoor unit which receives the successful pairing information is the outdoor unit of the air conditioner purchased by the user, the load of the outdoor unit of the air conditioner purchased by the user responds to the operation, and the indoor unit acquires that the load of the outdoor unit of the air conditioner purchased by the user is in an operating state, so that the successful pairing between the indoor unit and the outdoor unit of the air conditioner purchased by the user can be determined; if the outdoor unit which receives the successful pairing information is the outdoor unit of the air conditioner of other upstairs users, the load of the outdoor unit of the air conditioner purchased by the user cannot respond to the operation, and the indoor unit acquires that the load of the outdoor unit of the air conditioner purchased by the user is in a non-operation state, so that the situation that the indoor unit and the outdoor unit of the air conditioner purchased by the user are not successfully paired can be determined. Therefore, the embodiment of the invention can detect the pairing condition between the indoor unit and the outdoor unit under the condition of not increasing a hardware signal isolator, thereby reducing the cost of the air conditioner and improving the competitiveness of the air conditioner product.
It should be noted that the load may be a fan, a compressor, an expansion valve, a relay, a buzzer, or a lamp.
In addition, as shown in fig. 4 and fig. 5, fig. 4 is a flowchart of a method for detecting a pairing situation when the operation state information indicates that the load of the target outdoor unit is in an operation state according to an embodiment of the present invention, and fig. 5 is a flowchart of a method for detecting a pairing situation when the operation state information indicates that the load of the target outdoor unit is in a non-operation state according to an embodiment of the present invention.
As shown in fig. 4, the determination of the pairing state between the indoor unit and the target outdoor unit according to the operation state information in the step S200 includes, but is not limited to, the steps S310 and S320.
Step S310, when the running state information represents that the load of the target outdoor unit is in a running state;
and step S320, determining that the indoor unit and the target outdoor unit are successfully paired.
Specifically, if the outdoor unit that receives the pairing success information is the target outdoor unit, the load of the target outdoor unit responds to the operation.
Correspondingly, the running state information represents that the load of the target outdoor unit is in a running state, and then the indoor unit obtains that the load of the target outdoor unit is in the running state, so that the successful pairing between the target outdoor unit and the indoor unit can be determined.
As shown in fig. 5, the determination of the pairing state between the indoor unit and the target outdoor unit according to the operation state information in the step S200 includes, but is not limited to, the steps S410 and S420.
Step S410, when the running state information represents that the load of the target outdoor unit is in a non-running state;
and step S420, determining that the indoor unit and the target outdoor unit are failed to be paired.
Specifically, if the outdoor unit that receives the pairing success information is a non-target outdoor unit, that is, other outdoor units except for the target outdoor unit, the load of the target outdoor unit does not respond to the operation.
Correspondingly, the running state information represents that the load of the target outdoor unit is in a non-running state, and then the indoor unit acquires that the load of the target outdoor unit is in the non-running state, so that the situation that the target outdoor unit and the indoor unit are not successfully paired can be determined.
In addition, as shown in fig. 6, fig. 6 is a flowchart illustrating that the load operation of the indoor unit and the outdoor unit is controlled for a preset time according to an embodiment of the present invention.
The step S100 includes, but is not limited to, the step S500.
And S500, sending pairing success information to the outdoor unit through the power line, so that the outdoor unit drives the load of the outdoor unit to operate for a preset time according to the pairing success information.
Specifically, since the operation state information of the load of the target outdoor unit needs to be acquired after the load operation of the driving outdoor unit, if the duration of the load operation is short, the indoor unit may not acquire the operation state information of the load of the target outdoor unit, and thus the pairing condition between the target outdoor unit and the indoor unit cannot be accurately determined. In order to ensure that the indoor unit can acquire the running state information of the load of the target outdoor unit, the embodiment of the invention drives the load of the outdoor unit to run for a preset time.
