[0031] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0033] Figure 1 A schematic diagram of a power supply control system structure provided in an embodiment of the present application, the power supply control system includes:

[0034] A control board 100, a first switching element K0 and an uninterruptible power supply UPS.

[0035] The control board 100 includes a first interface P2 and a second interface P3. The first switch element K0 is electrically connected between the power supply terminal U0 and the input terminal of the uninterruptible power supply. The first interface P2 is electrically connected to the control terminal of the first switch element K0. The second interface P3 is electrically connected to the shutdown enable interface of the uninterruptible power supply.

[0036] The control board 100 is used to control the first switch element K0 to turn on based on the received power-on signal to turn on the uninterruptible power supply, or to control the first switch element K0 to turn off based on the received power-off signal and control the uninterruptible power supply to shut down through the second interface P3.

[0037] The uninterruptible power supply is used to electrically connect at least two power consumption units 200 and to supply power to the at least two power consumption units 200 simultaneously.

[0038] like Figure 1 As shown, in the embodiment of the present application, an uninterruptible power supply (UPS) is used to provide power to the power unit 200, which can be a power-consuming device such as a robotic arm in a medical beauty robot, and is not limited here. In some embodiments, multiple power units 200 need to be used at the same time, but it is necessary to control the simultaneous power on and off of multiple power units 200. In some cases, multiple power units 200 can be powered off at the same time to prevent accidents.

[0039] The control board 100 in the embodiment of the present application is used to control the power on or off of the uninterruptible power supply. When the uninterruptible power supply is turned on, the uninterruptible power supply can supply power to multiple power consumption units 200 simultaneously and separately. When the uninterruptible power supply is turned off, the uninterruptible power supply cuts off power to multiple power consumption units 200 at the same time.

[0040] In an embodiment of the present application, the uninterruptible power supply is configured to automatically power on when receiving a mains power supply, and to power off when disconnected from the mains power supply and receiving a shutdown enable signal.

[0041] The control board 100 in the embodiment of the present application is used to receive a power-on signal and a power-off signal. When receiving a power-on signal, the control board 100 can control the first switch element K0 to be turned on. Since the first switch element K0 is electrically connected between the mains power and the input end of the uninterruptible power supply, when the first switch element K0 is turned on, the uninterruptible power supply is directly connected to the mains power, so the uninterruptible power supply can be turned on.

[0042] When receiving a shutdown signal, the control board 100 can control the first switch element K0 to be disconnected, thereby disconnecting the uninterruptible power supply from the mains. However, the uninterruptible power supply will not be shut down directly at this time, but will be shut down based on the shutdown enable signal received by the second interface P3.

[0043] In summary, the uninterruptible power supply in the embodiment of the present application can be electrically connected to multiple power units 200 at the same time, supply power to multiple power units 200 simultaneously and separately, and can control the power on or off of the uninterruptible power supply through the control board 100 and the first switch element K0. When the uninterruptible power supply is turned on, it can supply power to multiple power units 200 at the same time, thereby turning on the power units 200. When the uninterruptible power supply is turned off, it no longer supplies power to multiple power units 200, thereby turning off the power units 200. Therefore, the present application can realize the simultaneous control of the power on and off of multiple power units 200, simplifying the operation process of turning on and off multiple power units 200.

[0044] Continue reading Figure 1 In some embodiments, the power supply control system further includes a first voltage conversion module S1. The control board 100 further includes a third interface P1. The first voltage conversion module S1 is electrically connected between the power supply terminal U0 and the third interface P1.

[0045] like Figure 1 As shown, the power supply terminal U0 represents the mains power, and the first voltage conversion module S1 can be used to convert the 220V AC power of the mains power into 24V DC power and input it into the third interface P1 of the control board 100 to provide power for the control board 100. Exemplarily, the first voltage conversion module S1 can be a rectifier, etc., which is not limited here.

[0046] Continue reading Figure 1 In some embodiments, the power supply control system further includes a second voltage conversion module S2. The control board 100 further includes a fourth interface P6, and the output end of the uninterruptible power supply is electrically connected to the fourth interface P6. The second voltage conversion module S2 is electrically connected between the output end of the uninterruptible power supply and the fourth interface P6.

[0047] like Figure 1 As shown, the second voltage conversion module S2 can convert the 220V AC power of the uninterruptible power supply into 24V DC power and input it into the fourth interface P6 of the control board 100 to provide power for the control board 100. Exemplarily, the first voltage conversion module S1 can be a rectifier, etc., which is not limited here.

[0048] Figure 2A schematic diagram of a circuit structure of a power supply control system provided in an embodiment of the present application. In some embodiments, the control board 100 includes a power-on module. The power-on module includes a second switch element SB1 and a third switch element K1. The first end of the second switch element SB1 is electrically connected to the third interface P1, and the second end of the second switch element SB1 is electrically connected to the control end of the third switch element K1. The first normally open interface K1-O2 of the third switch element K1 is electrically connected to the control end of the first switch element K0, and the second normally open interface K1-O1 of the third switch element K1 is electrically connected between the third interface P1 and the control end of the third switch element K1.

[0049] After the second switch element SB1 is closed, the first normally open interface K1 - O2 and the second normally open interface K1 - O1 of the third switch element K1 are closed, and the first switch element K0 is controlled to be turned on.

[0050] like Figure 2 As shown, it should be noted that Figure 2 Schematically illustrating multiple circuits, in which the same endpoint names indicate that the electrical signals corresponding to the endpoints are the same.

[0051] Continue reading Figure 2 , the second switch element SB1 can be a manual self-reset switch. After the mains is powered on, the first voltage conversion module S1 outputs a 24V electrical signal, that is, Figure 2 The LP2-24V and GND-E circuits in the circuit are powered on. After the second switch element SB1 is triggered (closed), the third switch element K1 is powered on, and the first normally open interface K1-O2 of the third switch element K1 is closed, thereby controlling the first switch element K0 to be closed, and the uninterruptible power supply is connected to the mains to start the uninterruptible power supply. Since there is a delay time from the input of the mains to the output of the AC power by the uninterruptible power supply, the embodiment of the present application sets the second normally open interface K1-O1 of the third switch element K1 in parallel with the second switch element SB1, and the second normally open interface K1-O1 of the third switch element K1 is closed to realize the self-locking function, thereby ensuring that the third switch element K1 is in a powered-on state.

[0052] Continue reading Figure 2In some embodiments, the control board 100 further includes a shutdown module. The shutdown module includes a fourth switch element SB2, a fifth switch element K2, and a sixth switch element K4. A first end of the fourth switch element SB2 is electrically connected to the fourth interface P6, and a second end of the fourth switch element SB2 is electrically connected to a control end of the fifth switch element K2 and a control end of the sixth switch element K4. A normally closed interface K2-C1 of the fifth switch element K2 is electrically connected between the second switch element SB1 and the third interface P1, and a normally open interface K2-O1 of the fifth switch element K2 is electrically connected between the fourth interface P6 and the control end of the fifth switch element K2. A normally open interface K4-O1 of the sixth switch element K4 is electrically connected between the fourth interface P6 and the second interface P3.

[0053] After the fourth switch element SB2 is closed, the normally closed interface K2-C1 of the fifth switch element K2 is disconnected, the normally open interface K2-O1 of the fifth switch element K2 is closed, the normally open interface K4-O1 of the sixth switch element K4 is closed, and the output signal of the second interface P3 triggers the uninterruptible power supply to shut down.

[0054] The fourth switch element SB2 can be a manual self-resetting switch. After the fourth switch element SB2 is triggered (closed), the fifth switch element K2 and the sixth switch element K4 are energized, and the normally open interface K2-O1 of the fifth switch element K2 is closed, so that the fifth switch element K2 is self-locked. The normally closed interface K2-C1 of the fifth switch element K2 is disconnected, the third switch element K1 is powered off, and the first switch element K0 is disconnected accordingly, so that the electrical connection between the uninterruptible power supply and the mains is disconnected. The normally open interface K4-O1 of the sixth switch element K4 is closed, and the uninterruptible power supply ( Figure 2 The UPS dry contact (shown in the figure) outputs a shutdown enable signal to control the shutdown of the uninterruptible power supply.

[0055] That is, through the above solution, it is possible to control the uninterruptible power supply to shut down through the fourth switch element SB2.

[0056] Continue reading Figure 2 In some embodiments, the shutdown module further includes a seventh switch element K5 and an eighth switch element K6. The control board 100 further includes a fifth interface P4, which is electrically connected to the subsystem 300. The control end of the seventh switch element K5 is electrically connected between the fourth interface P6 and the first end of the eighth switch element K6, and the normally open interface K5-O1 of the seventh switch element K5 is electrically connected between the fourth interface P6 and the control end of the fifth switch element K2. The second end of the eighth switch element K6 is grounded.

[0057] After the subsystem 300 outputs the shutdown signal, the eighth switch element K6 is controlled to be closed, and the normally open interface K5 - O1 of the seventh switch element K5 is closed.

[0058] The subsystem 300 in the embodiment of the present application represents a functional unit that can issue control instructions. In some implementations, the subsystem 300 may also be the power-consuming unit 200 in the above-mentioned embodiment, which is not limited here. However, the subsystem 300 is not powered through the fifth interface P4, but is powered through, for example, an output terminal.

[0059] Continue reading Figure 2 After the subsystem 300 outputs the shutdown signal, the eighth switch element K6 is closed, the seventh switch element K5 is powered on, and the normally open interface K5-O1 of the seventh switch element K5 is closed, so the fifth switch element K2 and the sixth switch element K4 are powered on, and the normally open interface K2-O1 of the fifth switch element K2 is closed, self-locking the fifth switch element K2. The normally closed interface K2-C1 of the fifth switch element K2 is disconnected, the third switch element K1 is powered off, and the first switch element K0 is disconnected accordingly, so the electrical connection between the uninterruptible power supply and the mains is disconnected. The normally open interface K4-O1 of the sixth switch element K4 is closed, and the uninterruptible power supply ( Figure 2 The UPS dry contact (shown in the figure) outputs a shutdown enable signal to control the shutdown of the uninterruptible power supply.

[0060] That is, based on the above solution, it is possible to control the uninterruptible power supply to automatically shut down through the subsystem 300.

[0061] Continue reading Figure 2 In some embodiments, the first normally closed interface K4 - C1 of the sixth switch element K4 is electrically connected between the fourth interface P6 and the output end of the uninterruptible power supply.

[0062] After the fourth switch element SB2 is triggered or the subsystem 300 outputs a shutdown signal, the first normally closed interface K4-C1 of the sixth switch element K4 is disconnected, so the control board 100 can be directly powered off to prevent accidents. Figure 2 Only the control board is illustrated, and the fourth interface P6 is not illustrated.

[0063] Continue reading Figure 2 In some embodiments, the power supply control system further includes a first indication unit LED2.

[0064] A first end of the first indicator unit LED2 is electrically connected to the output end of the uninterruptible power supply, and a second end of the first indicator unit LED2 is grounded.

[0065] Figure 2The first indicator unit LED2 is indicated as LED2. After the fourth switch element SB2 is triggered or the subsystem 300 outputs a shutdown signal, the normally open interface K4-O1 of the sixth switch element K4 is closed, and the first indicator unit LED2 is illuminated to indicate the shutdown state. When the uninterruptible power supply no longer outputs an electrical signal, the first indicator unit LED2 is turned off.

[0066] Continue reading Figure 2 In some embodiments, the present invention further includes a ninth switch element K3, a tenth switch element K12, an eleventh switch element K13 and a second indication unit LED1.

[0067] The control end of the eleventh switch element K13 is electrically connected to the fourth port P6 .

[0068] The control end of the tenth switch element K12 is electrically connected between the first normally open interface K1 - O2 of the third switch element K1 and the control end of the third switch element K1 .

[0069] A first end of the second normally closed interface K4 - C2 of the sixth switch element K4 is electrically connected to the fourth interface P6 , and a second end of the second normally closed interface K4 - C2 of the sixth switch element K4 is electrically connected to the control end of the ninth switch element K3 .

[0070] The first normally open interface K3-O1 of the ninth switch element K3 is electrically connected between the third interface P1 and the control end of the third switch element K1, and the second normally open interface K3-O2 of the ninth switch element K3 and the first normally open interface K13-O1 of the eleventh switch element K13 are connected in series between the fourth interface P6 and the first end of the second indication unit LED1.

[0071] The first normally open interface K12 - O1 of the tenth switch element K12 and the first normally closed interface K13 - C1 of the eleventh switch element K13 are electrically connected between the third interface P1 and the first end of the second indication unit LED1 .

[0072] A first end of the second normally open interface K13-O2 of the eleventh switch element K13 is electrically connected to the second end of the second indication unit LED1, a second end of the second normally open interface K13-O2 of the eleventh switch element K13 is grounded, a first end of the second normally closed interface K13-C2 of the eleventh switch element K13 is electrically connected to the second end of the second indication unit LED1, and a second end of the second normally closed interface K13-C2 of the eleventh switch element K13 is grounded.

[0073] When the second switch element SB1 is triggered, the tenth switch element K12 is energized, the first normally open interface K12-O1 of the tenth switch element K12 is closed, and the second indicator unit LED1 lights up. Figure 2The LP0-24V, GND-DEN circuit in the power supply is energized, the ninth switch element K3 and the eleventh switch element K13 are energized, the first normally open interface K3-O1 of the ninth switch element K3 is closed, the first normally closed interface K13-C1 of the eleventh switch element K13 is disconnected, and the power supply of the second indicator unit LED1 is changed to the LP0-24V, GND-DEN network. At this time, if the mains power is off, the state of the second indicator unit LED1 remains unchanged, and the second indicator unit LED1 can be used to indicate that the uninterruptible power supply is in the on state. If the mains power changes from the off state to the powered state, since the second normally open interface K3-O2 of the ninth switch element K3 is connected in parallel with the second switch element SB1, the third switch element K1 and the tenth switch element K12 are directly energized without triggering the second switch element SB1 again.
