[0042] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0043] The following describes a base station and a control method thereof, a cleaning device system, and a storage medium according to embodiments of the present disclosure with reference to the accompanying drawings.

[0044] FIG1 is a schematic diagram of the structure of a base station according to an embodiment of the present disclosure. As shown in FIG1 , the base station 100 includes: a connection terminal 110 , an activation self-locking circuit 120 , and a control unit 130 .

[0045] Among them, the base station 100 is detachably connected to the cleaning equipment (not shown in the figure) through the connecting terminal 110; the activation self-locking circuit 120 is connected to the connecting terminal 110; the control unit 130 is connected to the activation self-locking circuit 120, and is used to obtain the activation signal sent by the cleaning equipment through the activation self-locking circuit 120 when the base station 100 is connected to the cleaning equipment, and control the activation self-locking circuit 120 according to the activation signal to complete the activation self-locking operation, so that the base station 100 is in a working state.

[0046] The cleaning device may be any device with a cleaning function, such as a floor scrubber, a sweeper, or a vacuum cleaner, and the control unit 130 may be a microcontroller unit (MCU) or a single-chip microcomputer.

[0047] Specifically, after the user uses the floor scrubber to clean the floor, the user can place the floor scrubber on the base station 100 and detachably connect it to the base station 100 through the connection terminal 110 on the base station 100. The floor scrubber can automatically send an activation signal to the activation self-locking circuit 120 at the moment of connection with the base station 100, or the floor scrubber can be connected to the base station 100 and after the user presses the on / off button configured on the floor scrubber (not shown in the figure), send an activation signal to the activation self-locking circuit 120. After receiving the activation signal, the activation self-locking circuit 200 will transmit the activation signal to the control unit 130 (such as MCU / single-chip microcomputer). The control unit 130 will turn on the activation self-locking circuit 120 according to the activation signal, so that the activation self-locking circuit 120 completes the activation self-locking operation. After that, the base station 100 starts to operate, thereby realizing the functions of charging, adding water, pumping out sewage, and sterilizing the floor scrubber.

[0048] Thus, the activation signal is sent by the cleaning device to enable the activation self-locking circuit to complete the activation self-locking operation to activate the base station operation, without the need to design a separate switch button on the base station, thereby simplifying the button function design of the base station.

[0049] The connection terminal 110 , the activation self-locking circuit 120 and the control unit 130 are described in detail below.

[0050] In some embodiments, as shown in Figures 2a and 2b , the connection terminal 110 includes a first charging terminal 1, a second charging terminal 3, and a communication terminal 2. The first charging terminal 1 is connected to an external charging power source C+, the second charging terminal 3 is grounded, and the communication terminal 2 is connected to the activation self-locking circuit 120. The external charging power source C+ is used to charge the cleaning device when the base station 100 is connected to the cleaning device.

[0051] The external charging power source C+ can be a 30V external power source. It is understood that since the cleaning device is electrically powered, to ensure that the cleaning device has power, the user can place the cleaning device on the base station 100 after using it. The cleaning device has three pins corresponding to the first charging terminal 1, the second charging terminal 3, and the communication terminal 2, which can be connected accordingly. Once the cleaning device is successfully connected to the base station 100, the external charging power source C+ can promptly charge the cleaning device through the first charging terminal. In addition, by grounding the second charging terminal 3, leakage protection can be provided for the cleaning device. In addition, communication between the cleaning device and the base station 100 can be achieved via the communication terminal 2. As an example, an activation signal sent by the cleaning device can be transmitted via the communication terminal 2 to the activation self-locking circuit 120, and then transmitted to the control unit 130 via the activation self-locking circuit 120, so that the control unit 130 controls the activation self-locking circuit 120 according to the activation signal to complete the activation self-locking operation, thereby putting the base station 100 into operation.

[0052] It should be noted that the second charging terminal 3 is further connected to a transient voltage suppressor diode G1 before being grounded, for stabilizing the charging voltage.

[0053] In some embodiments, as shown in Figure 3, the control unit 130 includes a power enable terminal PWR EN and a signal enable terminal MCU EN, and the activation self-locking circuit 120 includes an activation sub-circuit 121, a power enable sub-circuit 122 and a self-locking sub-circuit 123. The activation sub-circuit 121 is connected to the communication terminal 2, the power enable sub-circuit 122 is connected to the power enable terminal PWR EN, and the self-locking sub-circuit 123 is connected to the signal enable terminal MCU EN.

[0054] The power enabling sub-circuit 122 is used to supply power to the control unit 130 ; the self-locking sub-circuit 123 is used to activate the self-locking circuit 120 to complete the self-locking operation.

[0055] Specifically, the activation sub-circuit 121 will be turned on instantaneously after receiving the activation signal. Then, the power enable sub-circuit 122 will be turned on as the activation sub-circuit 121 is turned on, so that the power enable sub-circuit 122 supplies power to the control unit 130 through the power enable terminal PWR EN. After the control unit 130 is powered, it sends a signal to the self-locking sub-circuit 123 through the signal enable terminal MCU EN. After the self-locking sub-circuit 123 receives the signal, it will keep the power enable terminal PWR EN in the on state so that the power enable terminal PWR EN can continuously supply power to the control unit 130, thereby completing the self-locking operation of the activation self-locking circuit 120.

[0056] In some embodiments, as shown in Figure 3, the activation sub-circuit 121 includes: a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a first capacitor C1, a second capacitor C2 and a first switch tube Q1, wherein one end of the first resistor R1 is connected to the communication terminal 2 of the base station 100, the other end of the first resistor R1 is connected to one end of the second resistor R2 and has a first node X1, the other end of the second resistor R2 is grounded, the positive electrode of the first capacitor C1 is connected to the first node X1, the negative electrode of the first capacitor C1 is connected to one end of the third resistor R3, the fourth resistor R4 and the second capacitor C2 are connected in parallel to form a first branch B1, one end of the first branch B1 is respectively connected to the other end of the third resistor R3 and the control end of the first switch tube Q1, the other end of the first branch B1 is connected to the first end of the first switch tube Q1 and grounded, and the second end of the first switch tube Q1 is connected to the power enable sub-circuit 122.

[0057] Continuing with reference to FIG3 , the power enable subcircuit 122 includes: a fifth resistor R5, a sixth resistor R6, a seventh resistor R7, a second switch tube Q2, a first diode D1, and a second diode D2, wherein one end of the fifth resistor R5 is connected to the first power supply DVCC and has a second node X2, the other end of the fifth resistor R5 is connected to the control terminal of the second switch tube Q2 and has a third node X3, the first end of the second switch tube Q2 is connected to the second node X2, the second end of the second switch tube Q2 is connected to one end of the sixth resistor R6, the other end of the sixth resistor R6 is connected to the anode of the first diode D1, the cathode of the first diode D1 is connected to the power enable terminal PWR EN, one end of the seventh resistor R7 is connected to the third node X3, the other end of the seventh resistor R7 is connected to the anode D3 of the second diode, and the cathode of the second diode D2 is connected to the activation subcircuit 121. The voltage value of the first power supply in this embodiment can be set to 12 volts.

[0058] Continuing with reference to FIG3 , the self-locking sub-circuit 123 includes an eighth resistor R8, a ninth resistor R9, and a third switch tube Q3, wherein one end of the eighth resistor R8 is connected to the signal enable terminal MCU EN, the other end of the eighth resistor R8 is connected to one end of the ninth resistor R9 and to the control end of the third switch tube Q3, the other end of the ninth resistor R9 is connected to the first end of the third switch tube Q3 and to ground, and the second end of the third switch tube Q3 is connected to the power enable sub-circuit 231.

[0059] The first switching transistor Q1 and the second switching transistor Q2 may be NPN-type MOS transistors. Due to the characteristics of NPN-type MOS transistors, when Vgs (i.e., the voltage between the gate and the source) is less than a certain value, the NPN-type MOS transistor will conduct, which is suitable for use when the source is grounded. Generally speaking, the NPN-type MOS transistor will conduct when the gate voltage reaches 4V or 10V.

[0060] The third switch tube Q3 may be an NPN transistor. Based on the characteristics of the NPN transistor, a high level will turn it on.

[0061] Specifically, when the cleaning device initially sends an activation signal to activate the self-locking circuit 120, the initial state of the communication terminal 2 is a 10V high-level activation state, and the 10V high-level voltage is transmitted to the activation sub-circuit 121. Specifically, the 10V high-level voltage is divided by the first resistor R1 and the second resistor R2, and then transmitted to the control terminal of the first switch Q1 (i.e., the gate of the NPN MOS transistor) through the first capacitor C1 and the third resistor R3. In addition, since the first terminal (source) of the first switch Q1 is grounded, the potential of the first terminal of the first switch Q1 is 0V. Therefore, the conduction condition of the first switch Q1 is met, and the first switch Q1 is turned on.

[0062] After the first switch Q1 is turned on, since the first terminal of the first switch Q1 is grounded, the first switch Q1 pulls down the voltage at the second terminal (i.e., the gate of the NPN MOS transistor) of the second switch Q2 via the second diode D2 and the seventh resistor R7, thereby turning on the second switch Q2. After the second switch Q2 is turned on, the 12V voltage output by the first power supply DVCC is sequentially transmitted to the power enable terminal PWR EN via the second switch Q2, the sixth resistor R6, and the first diode D1. Because the voltage currently transmitted to the power enable terminal PWR EN may still be too high and not meet the power supply requirements of the control unit 130, a DC-DC step-down unit B1 is further provided between the power enable sub-circuit 122 and the power enable terminal PWR EN. The DC-DC step-down unit S1 reduces the voltage to a preset voltage value, for example, 5V, before supplying power to the control unit 130.

[0063] It should be noted that, since the communication terminal 2 is initially in a high-level active state upon receiving the activation signal, it may no longer be in a high-level state some time after receiving the activation signal. This may cause the first switch Q1 to be in an off state, and thus the second switch Q2 to also be in an off state, thereby preventing the control unit 130 from being powered. Therefore, the embodiment of the present disclosure provides a self-locking sub-circuit 123 to keep the second switch Q2 in a continuously on state, thereby continuously powering the control unit 130.

[0064] Specifically, after receiving power, the control unit 130 causes the signal enable terminal MCUEN to continuously output a high-level signal. This high-level signal, after passing through the eighth resistor R8, turns on the third switch Q3. After the third switch Q3 is turned on, because the first terminal of the third switch Q3 is grounded, the third switch Q3 pulls down the voltage at the second terminal of the second switch Q2, which is pulled down via the second diode D2 and the seventh resistor R7, causing the second switch Q2 to remain on. This continuously supplies power to the control unit 130, thereby activating the self-locking operation of the self-locking circuit 120 and allowing the base station 100 to begin operation.

[0065] After the control unit 130 is powered, the base station 100 and the cleaning device can communicate with each other. The communication process between the base station 100 and the cleaning device is described in detail below.

[0066] FIG4 is a schematic structural diagram of a base station according to a third embodiment of the present disclosure. As shown in FIG4 (the activation self-locking circuit 120 is not shown), the base station 100 includes: a communication terminal 2, a communication circuit 420 and a control unit 130.

[0067] Among them, the base station 100 is communicatively connected to the cleaning equipment (not shown in the figure) through the communication terminal 2; the communication circuit 420 is connected to the communication terminal 2; the control unit 130 is connected to the communication circuit 420 through the signal transmitting end TX1 (not shown in the figure) and the signal receiving end RX1 (not shown in the figure), and when it is determined that the signal of the signal transmitting end TX1 and the signal receiving end RX1 are the same, the communication between the base station 100 and the cleaning equipment is realized.

[0068] For ease of explanation, the signal of the signal transmitting terminal TX1 is recorded as the initial signal, and the signal of the signal receiving terminal RX1 is recorded as the feedback signal. Specifically, after the control unit 130 is powered on, the control unit 130 will send an initial signal to the communication circuit 420 through the signal transmitting terminal TX1. The communication circuit 420 controls the corresponding parts of its internal circuit to be turned on and off according to the initial signal, and then outputs a feedback signal, and sends the feedback signal to the control unit 130 through the signal receiving terminal RX1. The control unit 130 compares the received feedback signal with the initial signal. When the feedback signal is the same as the initial signal, for example, both are high-level signals or both are low-level signals, the base station 100 and the cleaning equipment can communicate through the communication terminal 2, thereby performing subsequent self-cleaning (sewage extraction, sterilization) and other functions.

[0069] In some embodiments, as shown in reference figure 5, the communication circuit 420 includes a first communication sub-circuit 421, a second communication sub-circuit 422, a third communication sub-circuit 423 and a fourth communication sub-circuit 424. The first communication sub-circuit 421, the second communication sub-circuit 422, the third communication sub-circuit 423 and the fourth communication sub-circuit 424 all include a signal input terminal and a signal output terminal. The signal input terminal of the first communication sub-circuit 421 is connected to the signal sending terminal TX1 of the control unit 130, the signal output terminal of the first communication sub-circuit 421 is connected to the signal input terminal of the second communication sub-circuit 422, the signal output terminal of the second communication sub-circuit 422 is connected to the signal input terminal of the third communication sub-circuit 423, the signal output terminal of the third communication sub-circuit 423 is connected to the signal input terminal of the fourth communication sub-circuit 424, and the signal output terminal of the fourth communication sub-circuit 424 is connected to the signal receiving terminal RX1 of the control unit 130.

[0070] Continuing to refer to Figure 5, the first communication sub-circuit 421 includes a tenth resistor R10, an eleventh resistor R11, a twelfth resistor R12 and a fourth switch tube Q4. One end of the tenth resistor R10 serves as a signal input end of the first communication sub-circuit 421, the other end of the tenth resistor R10 is connected to the eleventh resistor R11 and has a fourth node X4, the other end of the eleventh resistor R11 is connected to the first end of the fourth switch tube Q4 and is grounded, the control end of the fourth switch tube Q4 is connected to the fourth node X4, the second end of the fourth switch tube Q4 is connected to one end of the twelfth resistor R12 and serves as a signal output end of the first communication sub-circuit 421, and the other end of the twelfth resistor R12 is connected to the second power supply DVCC.

[0071] The fourth switch tube Q4 may be an NPN transistor. Based on the characteristics of the NPN transistor, a high level may turn it on.

[0072] Specifically, when the communication unit 130 is powered, the output terminal of the communication unit 130 outputs a high-level signal to the signal input terminal of the first communication sub-circuit 421, namely, the left end of the tenth resistor R10 in the figure. This high-level signal reaches the control terminal (base) of the fourth switch Q4 through the tenth resistor R10 and the fourth node X4. The eleventh resistor R11 acts as a pull-down resistor connected to GND to stabilize the low-level voltage. The other end of the eleventh resistor R11 is connected to the first end (emitter) of the fourth switch Q4 and grounded, making the emitter potential of the fourth switch Q4 zero. This causes the base potential of the fourth switch Q4 to be higher than the emitter potential, causing its emitter junction to be forward biased, satisfying the conduction condition of the fourth switch Q4 and turning on the fourth switch Q4. After the fourth switch Q4 is turned on, since the first end of the fourth switch Q4 is grounded, the twelfth resistor R12 acts as a pull-down resistor, causing the power supply signal in the line between the second power supply DVCC and the fourth switch Q4 to be low-level (potential is 0). The low-level signal is output from the signal output end of the first communication sub-circuit 421 (ie, the end where the second end of the fourth switch tube Q4 is connected to one end of the twelfth resistor R12 ) to the signal input end of the second communication sub-circuit 422 .

[0073] In some embodiments, continuing to refer to Figure 5, the second communication sub-circuit 422 includes a thirteenth resistor R13, a fourteenth resistor R14, a fifteenth resistor R15, a third diode D3 and a fifth switch tube Q5, one end of the thirteenth resistor R13 serves as the signal input end of the second communication sub-circuit 422, the other end of the thirteenth resistor R13 is connected to the fourteenth resistor R14 and has a fifth node X5, the other end of the fourteenth resistor R14 is connected to the first end of the fifth switch tube Q5 and is grounded, the control end of the fifth switch tube Q5 is connected to the fifth node X5, the second end of the fifth switch tube Q5 is connected to the cathode of the third diode D3 and serves as the signal output end of the second communication sub-circuit 422, the anode of the third diode D3 is connected to one end of the fifteenth resistor R15, and the other end of the fifteenth resistor R15 is connected to the communication terminal.

[0074] The fifth switch tube Q5 may be an NPN transistor.

[0075] Specifically, the low-level signal output from the signal output terminal of the first communication sub-circuit 421 is sequentially input through the thirteenth resistor R13 and the fifth node X5 to the control terminal (base) of the fifth switching transistor Q5 (NPN transistor). Since a low level turns off the NPN transistor, the fifth switching transistor Q5 is turned off. When communication terminal 2 initially receives the activation signal, it outputs a high-level signal. Since the fifth switching transistor Q5 is turned off, the high-level signal output from communication terminal 2 in the initial communication state is input through the cathode of the third diode D3 to the signal input terminal of the third communication sub-circuit 423.

[0076] In some embodiments, as shown in reference figure 5, the third communication sub-circuit 423 includes a sixteenth resistor R16, a seventeenth resistor R17, an eighteenth resistor R18 and a sixth switch tube Q6, one end of the sixteenth resistor R16 serves as a signal input end of the third communication sub-circuit 423, the other end of the sixteenth resistor R16 is connected to the seventeenth resistor R17 and has a sixth node X6, the other end of the seventeenth resistor R17 is connected to the first end of the sixth switch tube Q6 and is grounded, the control end of the sixth switch tube Q6 is connected to the sixth node X6, the second end of the sixth switch tube Q6 is connected to one end of the eighteenth resistor R18 and serves as a signal output end of the third communication sub-circuit 423, and the other end of the eighteenth resistor R18 is connected to the second power supply DVCC.

[0077] The sixth switch tube Q6 may be an NPN transistor.

[0078] Specifically, the high-level signal output by the signal output terminal of the second communication sub-circuit 422 (i.e., the cathode of the third diode D3) is input to the control terminal (base) of the sixth switch Q6 via the sixteenth resistor R16 and the sixth node X6. With respect to the emitter (i.e., the first terminal) of the sixth switch Q6, since the other terminal of the seventeenth resistor R17 is connected to the first terminal of the sixth switch Q6 and grounded, the seventeenth resistor R17 acts as a pull-down resistor (stabilizing the low level), keeping the potential of the emitter of the sixth switch Q6 at 0. This causes the base potential of the sixth switch Q6 to be higher than the emitter potential, placing its emitter junction in a forward bias, satisfying the conduction condition for the sixth switch Q6, and turning on the sixth switch Q6. After the sixth switch tube Q6 is turned on, since the first end of the sixth switch tube Q6 is grounded, the eighteenth resistor R18 acts as a pull-down resistor so that the power supply signal of the line between the second power supply DVCC and the sixth switch tube Q6 is low level (potential is 0). The low-level signal is output from the signal output end of the third communication sub-circuit 423 (that is, the end connected to the second end of the sixth switch tube Q6 and one end of the eighteenth resistor R18) to the signal input end of the fourth communication sub-circuit 424.

[0079] In some embodiments, as shown in reference figure 5, the fourth communication sub-circuit 424 includes a nineteenth resistor R19, a twentieth resistor R20, a twenty-first resistor R21 and a seventh switch tube Q7, one end of the nineteenth resistor R19 serves as a signal input end of the fourth communication sub-circuit 424, the other end of the nineteenth resistor R19 is connected to the twentieth resistor R20 and has a seventh node X7, the other end of the twentieth resistor R20 is connected to the first end of the seventh switch tube Q7 and is grounded, the control end of the seventh switch tube Q7 is connected to the seventh node X7, the second end of the seventh switch tube Q7 is connected to one end of the twenty-first resistor R21 and serves as a signal output end of the fourth communication sub-circuit 424, and the other end of the twenty-first resistor R21 is connected to the second power supply DVCC.

[0080] The seventh switch tube Q7 may be an NPN transistor.

[0081] Specifically, the low-level signal output from the signal output terminal of the third communication sub-circuit 423 is input to the control terminal (base) of the seventh switch Q7 via the nineteenth resistor R19 and the seventh node X7, thereby turning off the seventh switch Q7. With the seventh switch Q7 turned off, the twenty-first resistor R21 acts as a pull-up resistor, stabilizing the signal output from the second power supply DVCC into a high-level signal that is output to the signal output terminal of the fourth communication sub-circuit 424.

[0082] Since the electrical signals at the signal input end of the first communication sub-circuit 421 and the signal output end of the fourth communication sub-circuit 424 are both high-level signals, communication between the cleaning device and the base station 100 can be achieved.

[0083] It should be noted that the voltage value of the second power supply DVCC is 5V.
