The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator in the present application. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.
Fig. 1 is a schematic structural diagram of an air conditioner according to an embodiment of the present invention. The embodiment of the invention provides an air conditioner, which comprises a communication module 1 and a control part 2.

and S13, when no fault occurs in the indoor unit and the outdoor unit, sending a fault-free signal to the communication module, so that when the communication module receives the fault-free signal, the firmware program is determined to be successfully upgraded.
In the present embodiment, after the control unit 2 obtains the upgraded firmware program, the upgraded firmware program is started, the air conditioner starts to operate, and the indoor unit and the outdoor unit of the air conditioner are self-detected. For example, the indoor unit self-test is to detect mechanisms such as an indoor heat exchanger, an indoor fan, an electric control board, and a damper of the indoor unit, and the outdoor unit self-test is to detect mechanisms such as a compressor and an outdoor fan of the outdoor unit. And when detecting that the indoor unit and the outdoor unit are not in fault, the controller sends a fault-free signal to the communication module so that the communication module judges that the OTA is successfully upgraded. At the moment, the applicability of the upgraded firmware program to the air conditioner can be ensured, the upgrading of the air conditioner is ensured to be effective, and the operation reliability and stability of the air conditioner are ensured.

and S22, after the burning of the firmware program before upgrading is finished, starting the firmware program before upgrading.
In this embodiment, after the control unit 2 receives the upgrade data packet, the firmware program running before the upgrade is stored in the backup storage area of the memory 3. Therefore, when the control unit 2 detects a failure of the indoor unit or the outdoor unit, the firmware program before the upgrade is acquired from the backup storage area, and the firmware program before the upgrade is started to be burned, so that the air conditioner starts to operate. At this time, the control part 2 processes the self-detection fault to avoid the air conditioner from being upgraded into a fault machine due to low-level errors, so that the air conditioner has the characteristics of error prevention and fool prevention and ensures the normal operation of the air conditioner.
In some embodiments, step S12 specifically includes: after the upgraded firmware program is started, correspondingly revising the operation mode parameters of the air conditioner; and respectively controlling the indoor unit and the outdoor unit to carry out self-detection according to the operation mode parameters. In the embodiment, the operation mode parameters of the air conditioner are self-corrected according to the upgraded firmware program, so that the air conditioner is operated according to the upgraded operation mode parameters, and the upgrading efficiency can be effectively improved.
In some embodiments, referring to fig. 5, a schematic flow chart of performing self-detection on an indoor unit and an outdoor unit according to an embodiment of the present invention includes:
s121, acquiring a first fault zone bit generated by the indoor unit in the self-detection process and a second fault zone bit generated by the outdoor unit in the self-detection process;
s122, judging whether the indoor unit and the outdoor unit have faults or not according to the first fault zone bit and the second fault zone bit;

s1222, when the first fault flag bit is not zero, detecting that the indoor unit has a fault;
and S1223, when the second fault flag is not zero, detecting that the outdoor unit has a fault.
In this embodiment, in the self-detection process, the controller determines whether the indoor unit and the outdoor unit have a fault according to the first fault flag and the second fault flag, so that whether the indoor unit and the outdoor unit have the fault is used as a determination condition for determining whether the OTA upgrade is successful.
In a specific embodiment, the control portion is configured to further include:
when the indoor unit or the outdoor unit is detected to have a fault, the corresponding fault zone bit and the equipment identifier of the air conditioner are sent to the cloud server through the communication module, so that the cloud server prohibits the air conditioner with the same type as the air conditioner corresponding to the equipment identifier from being upgraded until the upgrade data packet of the air conditioner corresponding to the equipment identifier is verified to be updated.
It should be noted that, when the control unit detects that the indoor unit or the outdoor unit has a fault, the control unit reports a corresponding fault flag and the device identifier of the air conditioner to the cloud server through the communication module. Therefore, the cloud server does not trigger OTA upgrading for the air conditioner corresponding to the equipment identifier, and the air conditioner with the same type as the air conditioner is forbidden to be upgraded. Meanwhile, the cloud server optimizes the upgrading data packet according to the fault zone bit until the limit of upgrading the air conditioner of the machine type is removed after the fault zone bit is optimized in place. Therefore, the embodiment of the invention greatly improves the effectiveness of the upgraded firmware program in the air conditioner and greatly improves the upgrading efficiency.
