[0024] S11, determining whether the outdoor unit is in a low standby state;

[0025] S12, pulse charging is performed on the outdoor unit based on the outdoor unit being in a low standby state;

[0026] S13, determining whether the monitoring time delay in the pulse charging process is greater than a preset threshold, and based on the monitoring time delay being greater than the preset threshold, adjusting the charging pulse time using the monitoring time delay, and pulse charging the outdoor unit according to the adjusted charging pulse time to maintain normal communication of the outdoor unit.

[0027] It should be noted that the step number "S1N" in the present specification does not represent the sequence of the air conditioner indoor and outdoor unit communication method, and the following will be specifically combined Figure 2 The air conditioner indoor and outdoor unit communication method of the present application is described.

[0028] Step S11, determining whether the outdoor unit is in a low standby state.

[0029] In the present embodiment, the low standby state is a state entered by the outdoor unit after controlling the switching power supply to be turned off based on the received standby instruction. In other words, before determining that the outdoor unit is in a low standby state, the indoor unit receives a remote control shutdown signal sent by a remote control terminal, and sends a standby instruction to the outdoor unit through the TX interface according to the remote control shutdown signal. The outdoor unit wakes up the power supply interface connected to the switching power supply according to the standby instruction, and sends an instruction to control the switching power supply to stop working, and enters a standby state.

[0030] It should be noted that the indoor unit and the outdoor unit can use standard communication methods such as RS485, and the rate can be in accordance with the standard format.

[0031] In an optional embodiment, determining whether the outdoor unit is in a low standby state, further comprises: based on the outdoor unit not being in a low standby state, maintaining normal operation.

[0032] Step S12, pulse charging the outdoor unit based on the outdoor unit being in a low standby state.

[0033] In the present embodiment, pulse charging the outdoor unit comprises: pulse charging the outdoor unit based on a preset pulse width modulation; wherein the preset pulse width modulation is determined based on a preset target charging voltage, an initial voltage of an electrolytic capacitor in the outdoor unit for charging, a charging speed of the electrolytic capacitor, and a charging voltage corresponding to each pulse width.

[0034] It should be noted that the indoor unit pulse charges the outdoor unit through the TX interface based on the preset pulse width modulation, and the preset pulse width modulation is represented as:

[0035] V t =V0+(V u -V0)× [1-EXP(-t / RC)]

[0036] Wherein, V t represents the charging voltage that can be reached corresponding to the pulse width t; V0 represents the initial voltage of the electrolytic capacitor; Vu represents a preset target charging voltage of the electrolytic capacitor; RC represents a charging speed of the electrolytic capacitor.

[0037] It should be noted that by charging the electrolytic capacitor of the outdoor unit by using the preset pulse width modulation, the energy supply for the main control unit MCU of the outdoor unit is maintained, ensuring the normal operation of the MCU in the low standby state of the outdoor unit.

[0038] In step S13, it is determined whether the monitoring time delay in the pulse charging process is greater than a preset threshold value, and based on the monitoring time delay being greater than the preset threshold value, the charging pulse time is adjusted using the monitoring time delay, and the outdoor unit is pulse charged according to the adjusted charging pulse time, maintaining the normal communication of the outdoor unit.

[0039] It should be noted that since the pulse charging will cause the components to attenuate or the line impedance to increase over time, it is necessary to monitor the pulse charging of the outdoor unit so as to timely determine whether the pulse charging time needs to be adjusted according to the monitoring time delay, thereby avoiding the situation of component attenuation or line impedance increase.

[0040] In this embodiment, the charging pulse time is adjusted using the monitoring time delay, which includes: determining the charging duration according to the preset pulse width modulation adopted by the pulse charging; adjusting the charging duration according to the monitoring time delay and a preset adjustment coefficient to obtain the adjusted charging pulse time.

[0041] It should be noted that the adjusted charging pulse time is represented as:

[0042] t out =t’+K×t d

[0043] Wherein, t out represents the adjusted charging pulse time, and t out <0.9×(t+t’); t’ represents the charging duration; K represents a preset adjustment coefficient, which can be set according to actual design requirements, such as being set between 0.5-5; t d represents the monitoring time delay.

[0044] Further, the charging duration is determined according to the preset pulse width modulation adopted by the pulse charging, which includes: determining a preset target charging voltage, an initial voltage of the electrolytic capacitor, a capacitance of the electrolytic capacitor and a charging current according to the preset pulse width modulation adopted by the pulse charging; obtaining the charging duration according to the preset target charging voltage, the initial voltage of the electrolytic capacitor, the capacitance of the electrolytic capacitor and the charging current.

[0045] It should be noted that the charging duration is represented as:

[0046]

[0047] wherein t' represents the charging time length; C represents the capacitance of the electrolytic capacitor; V0 represents the initial voltage of the electrolytic capacitor; V u represents the preset target charging voltage of the electrolytic capacitor; and I represents the charging current of the electrolytic capacitor.

[0048] In an optional embodiment, the determining whether the monitoring time delay in the pulse charging process is greater than the preset threshold value comprises: Figure 2 based on the monitoring time delay being not greater than the preset threshold value, continuing to pulse charge the outdoor unit according to the preset pulse width modulation.

[0049] In an optional embodiment, after the pulse charging of the outdoor unit, the method further comprises: receiving a remote start signal sent by a remote control terminal; and sending an exit low standby mode instruction to the outdoor unit according to the remote start signal, so as to control the outdoor unit to wake up the switching power supply to work and switch to the running mode.

[0050] In summary, the embodiments of the present application determine whether the outdoor unit is in a low standby state, pulse charge the outdoor unit when the outdoor unit is in the low standby state, ensure that the main control unit of the outdoor unit is powered when the outdoor unit is in the low standby state, and ensure the normal communication between the outdoor unit and the indoor unit. In addition, the time delay in the pulse charging process is monitored, so that it is determined whether the pulse charging time needs to be adjusted in a timely manner according to the monitoring time delay, thereby avoiding the situation that the component decays or the line impedance increases, improving the communication rate, and reducing the design cost.

The preset pulse width modulation is determined based on a preset target charging voltage, an initial voltage of an electrolytic capacitor in the outdoor unit for charging, a charging speed of the electrolytic capacitor, and a charging voltage corresponding to each pulse width.

[0060] It should be noted that the electrolytic capacitor of the outdoor unit is charged by using the preset pulse width modulation, so as to maintain the energy supply for the main control unit MCU of the outdoor unit, and ensure the normal operation of the MCU in the low standby state of the outdoor unit.

[0062] It should be noted that as the pulse charging time elapses, the components will be attenuated or the line impedance will be increased, so it is necessary to monitor the pulse charging of the outdoor unit, so as to timely determine whether the pulse charging time needs to be adjusted according to the monitoring time delay, so as to avoid the situation that the components are attenuated or the line impedance is increased.

[0063] Further, the time length determining unit comprises a parameter determining subunit configured to determine the preset target charging voltage, the initial voltage of the electrolytic capacitor, the capacitance of the electrolytic capacitor, and the charging current according to the preset pulse width modulation adopted by the pulse charging, and a time length determining subunit configured to obtain the charging time length according to the preset target charging voltage, the initial voltage of the electrolytic capacitor, the capacitance of the electrolytic capacitor, and the charging current.

[0064] In an optional embodiment, the pulse charging module 32 is further configured to continue to pulse charge the outdoor unit according to the preset pulse width modulation based on the monitoring time delay being less than the preset threshold.

[0065] In summary, the embodiment of the present application determines whether the outdoor unit is in a low standby state through the state determination module, and pulse charges the outdoor unit through the pulse charging module when the outdoor unit is in the low standby state, so as to ensure that the main control unit of the outdoor unit is powered when the outdoor unit is in the low standby state, and normal communication between the outdoor unit and the indoor unit is ensured. In addition, the time delay during the pulse charging process is monitored, so that the charging adjustment module can determine whether the pulse charging time needs to be adjusted in a timely manner according to the monitoring time delay, thereby avoiding the situation that the component decays or the line impedance increases, improving the communication rate, and reducing the design cost.

[0066] In an optional embodiment, the apparatus further comprises a signal receiving unit configured to receive a remote control startup signal sent by a remote control terminal after pulse charging the outdoor unit, and an instruction sending unit configured to send a low standby mode exit instruction to the outdoor unit according to the remote control startup signal, so as to control the outdoor unit to wake up the switching power supply to work and switch to the running mode.
