The embodiment of the present application provides a power supply system 10, which is mainly applied to an air conditioner powered by an external unit 200. Referring to fig. 1, a block diagram of a circuit structure of a power supply system 10 according to an embodiment of the present disclosure is shown. The power supply system 10 includes an indoor unit 100 and an outdoor unit 200, where the indoor unit 100 includes a first controller 110, a first power supply module 120, a first switch module 130, a first communication circuit 140, a third switch module 150, and a signal output end 160, and the outdoor unit 200 includes a second controller 210, a second switch module 220, a second power supply module 230, a second communication circuit 240, and an optical coupler 250.
The first power supply module 120, the first switch module 130, the signal output end 160, the second switch module 220 and the second controller 210 are electrically connected in sequence, the first power supply module 120, the third switch module 150, the first communication circuit 140 and the signal output end 160 are electrically connected in sequence, the signal output end 160, the optical coupler 250, the second communication circuit 240 and the second controller 210 are electrically connected in sequence, the second power supply module 230, the second switch module 220 and the second controller 210 are electrically connected in sequence, and the first controller 110 is further electrically connected with the first power supply module 120, the first switch module 130, the first communication circuit 140 and the third switch module 150 respectively.
The first power supply module 120 is electrically connected to the first switch module 130 and the first control module, and is configured to provide a working voltage for the first control module and provide a power signal for waking up the external unit 200. It is understood that the first power supply module 120 may include components such as a power supply, a rectifier bridge, and a transformer, and components for converting ac power output by the power supply into dc power through the rectifier bridge and the transformer, so as to provide an operating voltage for the first control module. In addition, the first power supply module 120 (power supply) can also directly output 220V ac voltage to the first switch module 130 to provide a power signal for waking up the outdoor unit 200. It should be noted that the power supply is conventional commercial power, and is used for outputting 220V alternating current signals including a live line (L) and a neutral line (N).
The first switching module 130 is configured to switch states under the control of the first controller 110 so as to control whether the first power supply module 120 can output a power signal to the outdoor unit 200. It should be noted that the first switch module 130 is in an off state in a default state, and can be switched to an on state after receiving the control signal of the first controller 110, so that the ac power provided by the first power supply module 120 is transmitted to the external unit 200 through the first switch module 130 and the signal output terminal 160.
Referring to fig. 2, a circuit diagram of a power supply system 10 according to an embodiment of the present disclosure is shown. It can be seen that the first switching module 130 can include a normally open relay. It will be appreciated that a normally open relay is always open with its coil not energized, and may switch to a closed state after the coil is energized. Therefore, the first controller 110 can control the state of the first switching module 130 by controlling the current on/off of the coil.
The first communication circuit 140 is used for exchanging data between the indoor unit 100 and the outdoor unit 200. The first communication circuit 140 may include two states, a normal communication state and a disabled communication state. The state of the first communication circuit 140 can be controlled by the first controller 110. It is understood that when the first communication circuit 140 is in the normal communication state, the first communication circuit 140 can transmit the communication voltage of 24V or 54V; when the first communication circuit 140 is in the disabled state, the first communication circuit 140 does not operate.
In an alternative embodiment, the first controller 110 may set the state of the first communication circuit 140 by controlling Transmit Data (TXD) of the internal unit 100. Specifically, if the first controller 110 sets RXD to 0, the first communication circuit 140 is in a communication disabled state; if the first controller 110 sets RXD to 1, the first communication circuit 140 is in a normal communication state.
The third switching module 150 is used for switching states under the control of the first controller 110 so as to control the normal power supply and communication states of the indoor unit 100. The third switching module 150 is in an off state in a default state, and can be switched to an on state after receiving a control signal of the first controller 110, so that the first power supply module 120 can transmit a signal through the third switching module 150 and the first communication circuit 140.
In an alternative embodiment, the third switching module 150 may also be a normally open relay, and the third switching module 150 is always in an off state until the control signal of the first controller 110 is not received, and is switched to an on state only after the control signal is received.
Referring to fig. 2, the live line of the first power supply module 120 is electrically connected to the first resistor R1, the first switch module 130, the anode of the first diode D1, the cathode of the first diode D1, and the first communication circuit 140 in series and then electrically connected to the signal output terminal 160, the first communication circuit 140 is also electrically connected to the neutral line of the first power supply module 120, the indoor unit 100 further includes a first capacitor C1 and a second diode D2, the first capacitor C1 is connected to the first communication circuit 140 in parallel, the anode of the second diode D2 is electrically connected to the live line N, and the cathode of the second diode D2 is electrically connected to the neutral line L.
It will be appreciated that by providing the first resistor R1, the value of the current on the loop can be limited. By providing the first diode D1, reverse damage to the first power supply module 120 in the event of a fault current in the circuit can be avoided. Through setting up second diode D2 and first electric capacity C1, can guarantee to have the pressure drop between live wire N and the zero line L of first power module 120, avoid taking place the short circuit problem that live wire N and zero line L lug connection lead to.
One end of the second switch module 220 is electrically connected to both the signal output terminal 160 and the second power supply module 230, and the other end of the second switch module 220 is electrically connected to the second controller 210. The second switch module 220 is used for switching states under the control of the second controller 210 to change the connection states of the second switch module 220 with the signal output terminal 160 and the second power supply module 230.
The second switch module 220 includes a first state and a second state. In a default condition, the second switch module 220 is in a first state, and at this time, the second switch module 220 is connected to the signal output end 160 and disconnected from the second power supply module 230; under the control of the second controller 210, the second switch module 220 can be switched from the first state to the second state, and when the second switch module 220 is in the second state, the second switch module 220 is connected to the second power supply module 230 and disconnected from the signal output terminal 160.

It can be seen that when the stationary contact is in conduction with the first movable contact, the second switch module 220 is in the first state; when the stationary contact is conducted with the second movable contact, the second switching module 220 is in the second state.
The second communication circuit 240 is used for communicating with the first communication circuit 140 to exchange data between the indoor unit 100 and the outdoor unit 200. For example, the shutdown command transmitted by the first communication circuit 140 is forwarded to the second controller 210, or the operation data of the external unit 200 is transmitted to the first communication circuit 140.
By arranging the optical coupler 250 and connecting the optical coupler 250 in series between the second communication circuit 240 and the signal output end 160, the second communication circuit 240 can be replaced to isolate the strong current output by the first power supply module 120 when the first switch module 130 is switched on, so that the second communication circuit 240 is prevented from being damaged by the strong current.
The first controller 110 is configured to control states of the first switch module 130, the first communication circuit 140, and the third switch module 150, so as to switch the indoor unit 100 to different states.

It can be understood that, by controlling the first switch module 130 to be turned on, the first power supply module 120 can output a power signal to the second controller 210, so that the second controller 210 is powered on, and the effect of waking up the second controller 210 is achieved. In addition, the second controller 210 is awakened only after the power-on command is received, and the second controller 210 and even the external unit 200 are not powered, so that the circuit of the external unit 200 does not consume electric energy, the power consumption of the air conditioner in standby is reduced, and the effect of saving energy is achieved.
The second controller 210 is configured to control the second switch module 220 to switch to the second state after being awakened for a first preset time, so that the second power supply module 230 supplies power to the second controller 210.
As can be understood, by controlling the second switch module 220 to switch to the second state after the first preset time, the second power supply module 230 of the external unit 200 supplies power to the second controller 210 after the second controller 210 is awakened, so as to achieve the normal power supply state of the external unit 200.
Referring to fig. 2, the outdoor unit 200 further includes a thermistor PTC, a second capacitor C2, and a detector, the signal output terminal 160, the thermistor PTC and the first moving contact of the single-pole double-throw switch are electrically connected in sequence, two input terminals of the detector are electrically connected to the stationary contact of the single-pole double-throw switch and the second communication circuit 240 respectively, two output terminals of the detector are electrically connected to the second controller 210, and two ends of the second capacitor C2 are electrically connected to two output terminals of the detector respectively.
It is understood that when the first switching module 130 is turned on, the first power supply module 120 charges the second capacitor C2 through the thermistor PTC, and the first preset time is the time required for fully charging the second capacitor C2.
The first controller 110 is further configured to set the state of the first communication circuit 140 to a communication disabled state when receiving the power-on command.
It can be understood that, by setting the state of the first communication circuit 140 to the communication disabled state, the first communication circuit 140 does not receive the signal, so as to avoid the first communication circuit 140 from being damaged by the strong current output by the first power supply module 120 when the first switch module 130 is turned on.
The first controller 110 is further configured to control the third switching module 150 to be turned on, control the first switching module 130 to be turned off, and set the state of the first communication circuit 140 to be a normal communication state after a second preset time when the first switching module 130 is turned on.

It should be noted that the second preset time is longer than the first preset time.
The first controller 110 is further configured to control the third switch module 150 to be turned off and control the first switch module 130 to be turned on again when the data of the outdoor unit 200 transmitted by the outdoor unit 200 is not received within a preset waiting period.

The first controller 110 is further configured to generate a fault notification message when the data of the outdoor unit 200 transmitted by the outdoor unit 200 is not received within a preset number of waiting periods.
