In order to make the installation and debugging of the air conditioning equipment faster, simpler and more convenient, the communication of each equipment in the air conditioning system is generally realized by using a power line carrier communication technology at present.

Power Line Communication (PLC) is a Communication method specific to a Power system, and is a technology for transmitting analog or digital signals at high speed by a carrier method using an existing Power line. The method has the greatest characteristic that data transmission can be carried out only by wires without erecting a network again.

Therefore, the power line carrier communication technology is applied to the air conditioning system, a special communication line is not required to be distributed, and the communication among all equipment in the air conditioning system can be effectively realized by using the power line. However, since the air conditioning system is a closed refrigerant system, after each device in the air conditioning system is installed, it needs to be paired and networked to realize control of the device in the air conditioning system, but the power supply grid is an open network environment, any device in the power line carrier communication network sends a signal to the power line, and all other devices in the power line carrier communication network can receive the signal. For example, a first air conditioning system and a second air conditioning system exist in the same power carrier communication network, the first air conditioning system is provided with a first inner unit and a first outer unit, the first inner unit and the first outer unit are connected through power line communication, the second air conditioning system is provided with a second inner unit and a second outer unit, the second inner unit and the second outer unit are also connected through power line communication, and when the air conditioning system is paired and networked under the power carrier communication network, because the first inner unit and the second inner unit can both receive signals from the first outer unit and the second outer unit, pairing errors can be caused.

According to the pairing networking method, the indoor unit is controlled to acquire and store first temperature information used for representing the temperature state of the indoor unit before the indoor unit is started, second temperature information used for representing the temperature state of the indoor unit after the indoor unit and the outdoor unit operate together for the first preset time is acquired, and whether the indoor unit and the outdoor unit are in the same air conditioning system or not can be known according to the first temperature information and the second temperature information; the indoor unit in the same air conditioning system with the outdoor unit generates and stores a first address corresponding to the indoor unit, and the outdoor unit and the indoor unit can be paired and networked with each other according to the first address, so that the indoor unit and the outdoor unit in different air conditioning systems can be prevented from being paired with each other while the pairing and networking are realized automatically. In addition, the outer unit sends a first instruction to the power line to enable the inner unit to be started, then the outer unit is started to refrigerate, the inner unit is started with a fixed opening and a fixed wind gear, deviation caused by inconsistency of refrigerating time of the inner unit or inconsistency of opening of the inner unit or wind gear of the inner unit of second temperature information acquired by the inner unit can be avoided, and therefore whether the inner unit and the outer unit are in the same air conditioning system or not can be judged more accurately according to the first temperature information and the second temperature information. In summary, the pairing networking method of the embodiment of the invention can realize automatic pairing networking of the internal unit and the external unit of the air conditioning system, and can avoid mutual pairing of the internal unit and the external unit in different air conditioning systems under the same power carrier communication network, thereby improving the use experience of users.

step 2610, when the network deployment confirmation signal includes the real address of the internal machine, the real address is used as the communication address of the internal machine;

in step 2620, when the networking acknowledgement signal includes the virtual address of the internal machine, a real address is allocated to the internal machine and the real address is used as the communication address of the internal machine.

In one embodiment, the internal unit receives a networking signal from the external unit from a power line, the networking signal comprises a first address corresponding to the internal unit, namely the external unit sends the networking signal to the internal unit in a roll call mode, the first address configuration state of the internal unit can be two, including a real address and a virtual address, if the internal unit has the real address, when the internal unit receives the networking signal carrying the corresponding real address, the internal unit responds to the currently received networking signal by a networking confirmation signal to feed back the real address to the external unit; if the internal machine has the virtual address, when the internal machine receives a networking signal carrying the corresponding virtual address, the internal machine responds to the currently received networking signal, feeds back the virtual address to the external machine through a networking confirmation signal, receives the real address distributed by the external machine, stores the real address in the local and takes the real address as a communication address for data interaction with the external machine.

The outer machine sends the networking signals carrying the first address to the corresponding inner machine through the power line, and it can be understood that the outer machine sends the networking signals to the inner machine in a roll call mode, after the inner machine corresponding to the first address receives the networking signals, the outer machine can send the networking confirmation signals to the outer machine to feed back that the outer machine has the first address, the outer machine determines that the corresponding inner machine is found according to the received networking confirmation signals, and determines the communication address of the inner machine according to the first address sent to the outer machine, therefore, pairing networking of the inner machine and the outer machine is achieved, the inner machine is addressed in a roll call mode, the inner machine with the corresponding relation can be accurately found, and omission in the addressing process is avoided.

It should be noted that, when the external machine sends the networking signal carrying the real address to the corresponding internal machine, the networking acknowledgement signal fed back by the internal machine represents that the networking acknowledgement signal itself has the real address, when the external machine sends the networking signal carrying the virtual address to the corresponding internal machine, the networking acknowledgement signal fed back by the internal machine represents that the networking acknowledgement signal itself has the virtual address, and then the real address allocation from the external machine is received and the real address is stored locally.

It can be understood that omission can be reduced by the outer machine through multiple rounds of roll calling, so that each inner machine under the same power carrier communication network can make feedback, the inner machine remembering the real address can respond to the real address roll calling of the outer machine, and after the outer machine detects that the inner machine remembering the real address is on line, the inner machine can obtain the feedback of the outer machine, so that networking completion identification is generated, and automatic addressing is not participated in the next round of real address roll calling.

It is understood that both real and virtual address roll names may last for multiple rounds.

In an embodiment, the automatic addressing is executed by powering on the external unit and the internal unit after each power failure, if the air conditioning system is powered on again after being used for a period of time, the external unit can repeatedly perform the automatic addressing, it can be understood that if the external unit and the corresponding internal unit are paired and networked before the power failure, data of the air conditioning system is cleared after the power failure, the external unit searches the internal unit in the same air conditioning system again and performs the pairing and networking with the corresponding internal unit, the state of the internal unit can be updated in time, and the control stability of the air conditioning system is ensured. In addition, in consideration of the situation that the number of the internal machines is large, in order to reduce the number of addressing times of the external machine, an associated address book can be arranged in a local storage area of the external machine so as to record the communication addresses of the internal machines which are successfully paired and networked.

It is understood that the address pool set locally by the external unit may function as the above-mentioned associated address book, and the real address assigned to the internal unit is not popped from the address pool, but represents that the real address is associated by changing the state of the real address in the address pool.

As shown in fig. 23, fig. 23 is a schematic topology diagram of an air conditioning system 100 according to a fourth embodiment of the present invention, where the air conditioning system 100 includes an outdoor unit 110 and at least one indoor unit 120, and the outdoor unit 110 and the indoor unit 120 are communicatively connected through a power line 130;

the external unit 110 is also used for starting up the internal unit 120 when the starting up is completed;

the internal unit 120 is further configured to acquire and store second temperature information after a first preset time, where the second temperature information is used to represent a temperature state of the internal unit 120 after the internal unit 120 and the external unit 110 operate together for the first preset time;

the indoor unit 120 is further configured to generate and store a first address corresponding to the indoor unit 120 according to the first temperature information and the second temperature information;

The air conditioning system 100 of the embodiment of the invention comprises an outer unit 110 and at least one inner unit 120, wherein the inner unit 120 is in communication connection with the outer unit 110 through a power line 130, first temperature information used for representing the temperature state of the inner unit 120 before starting is obtained and stored by controlling the inner unit 120, second temperature information used for representing the temperature state of the inner unit 120 after the inner unit 120 and the outer unit 110 run together for a first preset time is obtained, and whether the inner unit 120 and the outer unit 110 are in the same air conditioning system 100 or not can be known according to the first temperature information and the second temperature information; the first address corresponding to the indoor unit 120 is generated by the indoor unit 120 in the same air conditioning system 100 as the outdoor unit 110 and stored in the indoor unit 120, and the outdoor unit 110 and the indoor unit 120 can perform pairing networking according to the first address, so that the indoor unit 120 and the outdoor unit 110 in different air conditioning systems 100 can be prevented from being paired with each other while the pairing networking is automatically performed. In addition, the outer unit 110 sends the first instruction to the power line 130 to start the inner unit 120, and then the outer unit 110 starts to cool, and the inner unit 120 starts with a fixed opening and a wind gear, so that the second temperature information obtained by the inner unit 120 can be prevented from generating deviation due to inconsistent cooling time of the inner unit 120 or inconsistent opening of the inner unit 120 or wind gear, and whether the inner unit 120 and the outer unit 110 are in the same air conditioning system 100 can be more accurately judged according to the first temperature information and the second temperature information. To sum up, the pairing and networking method of the embodiment of the present invention can realize automatic pairing and networking of the indoor unit 120 and the outdoor unit 110 of the air conditioning system 100, and can prevent the indoor unit 120 and the outdoor unit 110 in different air conditioning systems 100 from being paired with each other under the same power carrier communication network, thereby improving the user experience.

Referring to fig. 24, fig. 24 is a schematic topology diagram of another air conditioning system according to a fourth embodiment of the present invention, in the example of fig. 24, a first air conditioning system 200 and a second air conditioning system 300 exist in the same power carrier communication network, the first air conditioning system 200 is provided with a first inner unit 210 and a first outer unit 220, the first inner unit 210 and the first outer unit 220 are communicatively connected through a power line 130, the second air conditioning system 300 is provided with a second inner unit 310 and a second outer unit 320, the second inner unit 310 and the second outer unit 320 are also communicatively connected through the power line 130, and the first inner unit 210, the second inner unit 310, the first outer unit 220, and the second outer unit 320 are all connected to the same store line, when the air conditioning system is paired and networked under the power carrier communication network, since both the first inner unit 210 and the second inner unit 310 can receive signals from the first outer unit 220 and the second outer unit 320, thus causing pairing errors. In the technical scheme of the present invention, when the first indoor unit 210 and the second indoor unit 310 under the first air conditioning system 200 are paired and networked, the first indoor unit 210 and the second indoor unit 310 first obtain a first temperature value at a central pipe of each of the first indoor unit 210 and the second indoor unit 310, the first outdoor unit 220 sends a first instruction to the power line 130, the first outdoor unit 220 is powered on, the first indoor unit 210 and the second indoor unit 310 are both powered on in response to the first instruction, after the first outdoor unit 220, the first indoor unit 210 and the second indoor unit 310 operate together for a first preset time, the first indoor unit 210 and the second indoor unit 310 obtain a second temperature value at the central pipe of each of the first indoor unit 210 and the second indoor unit 310 obtain an absolute value after calculating a difference between the second temperature value and the first temperature value measured by the first indoor unit 210 and the second indoor unit 310, and compare the absolute value with a reference value stored in the first indoor unit 210 and the second indoor unit 310 in advance. The reference value is the minimum value of the temperature change that should be generated after the indoor unit and the outdoor unit in the same air conditioning system operate together for the first preset time, and since the first outdoor unit 220 and the first indoor unit 210 are located under the first air conditioning system 200, the first indoor unit 210 can smoothly perform heating or cooling under the action of the first outdoor unit 220, and thus the temperature difference value obtained by the first indoor unit 210 is greater than the reference value. Because the second indoor unit 310 and the first indoor unit 210 do not belong to the same air conditioning system, the second indoor unit 310 cannot cool or heat under the action of the first outdoor unit 220 any more, and therefore, whether the indoor unit and the outdoor unit belong to the same air conditioning system under the same power line carrier communication network can be judged by judging whether the temperature difference is greater than a preset value, so that pairing networking is performed.

Therefore, the pairing networking method provided by the embodiment of the invention can be used for acquiring and storing first temperature information for representing the temperature state of the indoor unit before the indoor unit is started by controlling the indoor unit, then acquiring second temperature information for representing the temperature state of the indoor unit after the indoor unit and the outdoor unit jointly run for a first preset time, and obtaining whether the indoor unit and the outdoor unit are in the same air conditioning system or not according to the first temperature information and the second temperature information; the indoor unit in the same air conditioning system with the outdoor unit generates and stores a first address corresponding to the indoor unit, and the outdoor unit and the indoor unit can be paired and networked with each other according to the first address, so that the indoor unit and the outdoor unit in different air conditioning systems can be prevented from being paired with each other while the pairing and networking are realized automatically. In addition, in the above embodiment, the time point when the external unit performs the power-on cooling or heating is after the external unit sends the first instruction to the power line so that the internal unit is powered on, and therefore the internal unit in the same power carrier communication network can operate for the same time as the external unit, and the second temperature information acquired by the internal unit can be prevented from generating deviation due to the fact that the time for the internal unit and the external unit to work together is different.
