The first power supply unit 112 is electrically connected to the first control unit 111, and is configured to provide a working voltage to the first control unit 111. In an alternative embodiment, the first power unit 112 includes a power source, a rectifier bridge and a transformer, and the power source, the rectifier bridge and the transformer are electrically connected in sequence. The rectifier bridge is used for converting alternating current input by a power supply into direct current, and the transformer is used for adjusting voltage values output to other units by the rectifier bridge.
It should be noted that the first power supply unit 112 includes output terminals including an N terminal and an L terminal; the N end is a zero line interface of the first power supply unit 112, the L end is a live line interface of the first power supply unit 112, and when the live line and the zero line form a loop, the first power supply unit 112 can normally output a power supply signal.
The first switching unit 113 is used to switch states under the control of the first control unit 111. The first switch unit 113 may be a single-pole single-throw switch, a high-power triode, a silicon controlled rectifier, a solid-state relay, an Insulated Gate Bipolar Transistor (IGBT), a MOS Transistor, or the like.
Please refer to fig. 2, which is a circuit diagram of a low power consumption control system 100 according to the present invention. Fig. 2 illustrates an example in which the first switch unit 113 is a single-pole single-throw switch K1, and details of the electrical connection relationship between the first switch unit 113 and other units. The active end of the single-pole single-throw switch K1 is electrically connected to the L-terminal of the first power supply unit 112, and the fixed end of the single-pole single-throw switch K1 is electrically connected to the N-terminal of the first power supply unit 112 through the voltage stabilizing unit 115. Therefore, when the first switch unit 113 is closed, the N terminal of the first power supply unit 112 is electrically connected to the L terminal of the first power supply unit 112, and the first power supply unit 112 can normally output a power supply signal; when the first switching unit 113 is turned off, the N terminal of the first power supply unit 112 is electrically disconnected from the L terminal of the first power supply unit 112, and the first power supply unit 112 cannot normally output a power supply signal.
One end of the voltage stabilizing unit is connected to the N-terminal of the first power supply unit 112, and the other end of the voltage stabilizing unit is electrically connected to the first switching unit 113. It can be understood that, when the first switch unit 113 is closed, the N terminal of the first power supply unit 112 is electrically connected to the L terminal of the first power supply unit 112 through the voltage regulation unit.
Referring to fig. 2, the voltage regulator unit 115 includes a second voltage regulator ZD2, a first capacitor C1, and a fifth resistor R5, the second voltage regulator ZD2 is connected in parallel with the first capacitor C1 and the fifth resistor R5, an anode of the second voltage regulator ZD2 is electrically connected to the N terminal of the first power supply unit 112, and a cathode of the second voltage regulator ZD2 is electrically connected to the L terminal of the first power supply unit 112 through the first switch unit 113.
It can be understood that, by providing the voltage stabilizing unit 115, when the first switch unit 113 is closed, a normal voltage drop between the N terminal of the first power supply unit 112 and the L terminal of the first power supply unit 112 is ensured, and a problem that the power supply signal cannot be output to the outer unit 120 due to a short circuit is avoided.
The first communication circuit 114 is used for receiving the operation data transmitted by the external unit 120 and transmitting the control signal, the operation data, etc. of the internal unit 110 to the external unit 120. In this embodiment, the first communication circuit 114 is configured to transmit the power signal transmitted by the first power unit 112 to the wake-up circuit 124 when the first switch unit 113 is closed.
With reference to fig. 2, the internal unit 110 further includes a third diode D3 and a sixth resistor R6, the first communication circuit 114 is connected in series with the third diode D3 and the sixth resistor R6 and then electrically connected to the second communication circuit 125 and the wake-up circuit 124, the anode of the third diode D3 is electrically connected to the first communication circuit 114, and the cathode of the third diode D3 is electrically connected to the wake-up circuit 124 and the second communication circuit 125.
As can be appreciated, since the third diode D3 is reversely connected to the outer unit 120, when the current in the loop is too large due to a short circuit or the like of the outer unit 120, the third diode D3 can effectively prevent the circuit of the inner unit 110 from being affected by a fault of the outer unit 120.
The first control unit 111 is configured to control the first switch unit 113 to be closed when receiving the power-on command. It is understood that the power-on command may be generated by a user operating a remote controller. That is, when the low power consumption control system 100 is in the standby state and the first control unit 111 does not receive the power-on command, the first switch unit 113 is in the off state, and the first power unit 112 cannot output the power signal; when the first control unit 111 receives the power-on command, it controls the first switch unit 113 to close, so that the first power unit 112 can normally transmit the power signal to the wake-up circuit 124 through the first communication circuit 114.
The second communication circuit 125 is electrically connected to the wake-up circuit 124 and the first communication circuit 114, and is configured to receive the control signal and the operation data transmitted by the indoor unit 110 and transmit the operation data of the outdoor unit 120 to the indoor unit 110.
The wake-up circuit 124 is configured to close in response to a power signal transmitted by the first power supply unit 112. Meanwhile, the wake-up circuit 124 may also be turned off under the control of the second control unit 121.
It can be understood that, when the wake-up circuit 124 is closed, the first power unit 112 is communicated with the second power unit 122, so that the first power unit 112 sequentially passes through the first communication circuit 114 and the wake-up circuit 124 to supply power to the second power unit 122, so that the second power unit 122 supplies power to the second control unit 121 to wake up the second control unit 121.
Referring to fig. 2, the wake-up circuit 124 includes a first switch transistor BJT1, a second switch transistor MOS1, and a first switch Q1, the first communication circuit 114 is electrically connected to a base of the first switch transistor BJT1, an emitter of the first switch transistor BJT1 is electrically connected to an N-terminal of the first power unit 112 through the first switch Q1, an emitter of the first switch transistor BJT1 is electrically connected to a collector of the first switch transistor BJT1 through the first resistor R1, a collector of the first switch transistor BJT1 is electrically connected to a gate of the second switch transistor MOS1 through the second resistor R2, a drain of the second switch transistor MOS1 is electrically connected between the second switch unit 123 and the second power unit 122, an L-terminal of the first power unit 112 is electrically connected to a source of the second switch transistor MOS1 through the thermistor PTC, and a source of the second switch transistor 1 is electrically connected to a collector of the first switch transistor BJT1 through the third resistor R3.
It can be understood that, after the first switch unit 113 is closed, the first power unit 112 outputs a power signal to the base of the first switch transistor BJT1, at this time, the first switch transistor BJT1 is turned on, and outputs a high-level signal to the gate of the second switch transistor MOS1, so that the second switch transistor MOS1 is also turned on, and thus the first power unit 112 is communicated with the second power unit 122 through the first switch unit 113, the first communication circuit 114, the first switch transistor BJT1, and the second switch transistor MOS 1.
In the embodiment shown in the figure, the first switching transistor BJT1 is a triode, and the second switching transistor MOS1 is a MOS transistor. In other embodiments, the first switching transistor BJT1 may also be a switching device such as a thyristor, a relay, or a MOS transistor; the second switching tube MOS1 may also be a high-power transistor, a thyristor, a solid-state relay, a relay, an optical relay, or other switching devices.
In addition, it should be noted that the first switch Q1 is closed by default; therefore, once the base of the first switching transistor BJT1 receives the power signal, the wake-up circuit 124 can be in the closed state; however, once the first switch Q1 is switched to the off state under the control of the second control unit 121, the wake-up circuit 124 is in the off state. Wherein, once the first switch Q1 is turned off, the first power supply unit 112 cannot supply power to the second power supply unit 122 through the wake-up circuit 124.
In an alternative embodiment, the wake-up circuit 124 further includes a first diode D1 and a fourth resistor R4, the first communication circuit 114 is electrically connected to the base of the first switch BJT1 after being connected in series with the first diode D1 and the fourth resistor R4, the anode of the first diode D1 is electrically connected to the first communication circuit 114, the cathode of the first diode D1 is electrically connected to the fourth resistor R4, and the second communication circuit 125 is electrically connected between the anode of the first diode D1 and the first communication circuit 114.
It can be understood that, since the first diode D1 is reversely connected to the second communication circuit 125, the first diode D1 can effectively prevent the current in the wake-up circuit 124 from affecting the second communication circuit 125, and ensure the stability of the second communication circuit 125. In another alternative embodiment, the wake-up circuit 124 further includes a second diode D2, the second diode D2 is connected in series between the thermistor PTC and the source of the second switching MOS1, the anode of the second diode D2 is electrically connected to the thermistor PTC, and the cathode of the second diode D2 is electrically connected to the source of the second switching MOS 1.
It is understood that the second diode D2 is connected to the first power unit 112 in a reverse direction, which can avoid the problem that the wake-up circuit 124 affects the first power unit 112 when a fault (e.g. short circuit) occurs, thereby affecting the power supply.
The second control unit 121 is configured to control the second switch unit 123 to close after being woken up.
The second switch unit 123 may be, but not limited to, a single-pole single-throw switch, a high-power triode, a silicon controlled rectifier, a solid-state relay, an Insulated Gate Bipolar Transistor (IGBT), an MOS Transistor, and the like.
It can be understood that after the second control unit 121 is awakened, the motor can be controlled to operate, so that the load of the outer unit 120 is increased, and thus the resistance of the thermistor PTCPTC is increased, at this time, the current transmitted through the thermistor PTCPTC is not enough to load the load of the outer unit 120, and therefore, the second switch unit 123 needs to be controlled to be closed again, so that the awakening circuit 124 is short-circuited, and thus, the outer unit 120 can obtain a sufficient current.
In addition, the second control unit 121 is further configured to control the first switch Q1 to be turned off after being woken up, so that the second communication circuit 125 operates normally.
It is understood that in the state where the first switch Q1 is closed, the signal transmitted by the first communication circuit 114 always transmits a signal to the wake-up circuit 124, which is liable to affect the normal communication of the second communication circuit 125. Therefore, in order to ensure that the inner unit 110 and the outer unit 120 can exchange data normally after the outer unit 120 is woken up, the second control unit 121 controls the first switch Q1 to be turned off after controlling the second switch unit 123 to be turned on.
Therefore, the principle of the utility model is that: when receiving a power-on command, the first control unit 111 controls the single-pole single-throw switch K1 to be turned on, so that the first power supply unit 112 outputs a power supply signal to the base of the first switching transistor BJT1 through the voltage stabilizing unit 115 and the first communication circuit 114, and at this time, the first switching transistor BJT1 is turned on and outputs a high level signal to the gate of the second switching transistor MOS1, so that the second switching transistor MOS1 is turned on and outputs a signal to the second power supply unit 122 to wake up the second control unit 121; to ensure that the input current can drive the load to operate, the second control unit 121 controls the second switch unit 123 to be closed after being awakened, so that the first power supply unit 112 directly supplies power to the second power supply unit 122; in order to ensure the normal communication between the inner unit 110 and the outer unit 120, the second control unit 121 controls the first switch Q1 of the wake-up circuit 124 to be turned off; to this end, the low power control system 100 enters a normal operating mode.

It should be noted that any one of the inner units 110 in this embodiment is substantially similar to the inner unit 110 provided in the first embodiment, and is not described herein again. However, it can be understood that in the present embodiment, when the first control unit 111 of any one of the internal units 110 receives the power-on command, the corresponding first switch unit 113 is controlled to be closed to supply power to the external unit, so that the external unit 120 can be awakened.
