[0026] The present disclosure will be further described in conjunction with the drawings and embodiments.

However, the present disclosure can be embodied in many different forms and should not be construed as limited to the specific aspects set forth herein.

[0027] In the current market, household wet household electrical appliances are favored by consumers for their high cleaning efficiency. Currently, further improving the maintenance efficiency on the traditional household wet household electrical appliance power supply device has become a trend.

[0028] In this disclosure, the term "household electrical device" can be used herein to describe various types of household electrical devices, including household cleaning devices configured to provide some semi-autonomous or autonomous capabilities. Examples of household cleaning devices include: a floor cleaning machine, a vacuum cleaner with mopping functionality, a robotic sweeper with scrubbing functionality, a window cleaning robot, etc.

[0029] In the example where the household electrical device is a floor cleaning machine, the household electrical device can include an on-board processing device configured to receive some information or instructions, e.g., from a human operator (e.g., through a remote computing device), and semi-autonomously manipulate the household electrical device to clean a floor and / or perform a power supply device maintenance of the household electrical device in accordance with the received information or instructions.

[0030] Figure 1 One example of a system for establishing a communication schedule between a maintenance base station 101 and a surface cleaning device 102 is shown. In various examples, the maintenance base station 101 can be connected to a charging circuit 103' of the surface cleaning device 102 through a charging circuit 103. For example, the charging circuit 103 can include a pair of charging terminals having a positive terminal 104 and a negative terminal 105. These are respectively used to interface with positive terminals 104' and 105' of the charging circuit 103' of the surface cleaning device 102. In one example, the charging terminals 104, 104', 105, 105' described above can be one of a pair of standard charging terminals used in connection with charging terminals of the maintenance base station 101 and the surface cleaning device 102. Based on such an example, the maintenance base station 101 and the surface cleaning device 102 can communicate current instructions including communication information and direct current information.

[0031] In further examples, the communication between the maintenance base station 101 and the surface cleaning device 102 can be conducted through one charging terminal of the charging circuit 103 and one charging terminal of the charging circuit 103' in accordance with a communication protocol. In another example, the power line communication between the controller 200 in the maintenance base station 101 and the surface cleaning device 102 is conducted through the positive terminals 104 and 104' connecting the maintenance base station 101 and the surface cleaning device 102.

[0032] Some advantages of communicating via the positive terminals 104 and 104' instead of adding an additional pair of communication terminals include eliminating the need for a communication cable; charging and communication are achieved directly with just the two wires, the positive and negative charging terminals, reducing product design costs. Furthermore, using orthogonal frequency division multiplexing (OFDM) technology for communication between the maintenance base station 101 and the surface cleaning device 102 may also be advantageous. For example, this power line communication technology facilitates communication between the maintenance base station 101 and the surface cleaning device 102 using existing wiring in the charging circuits of standard surface cleaning devices and maintenance base stations. Example methods for transmitting data via power lines can use carrier signals with frequencies different from the power signals.

[0033] In one example, the communication signals and power supply signals between the maintenance base station 101 and the surface cleaning device 102 can be time-division multiplexed, which may be beneficial for reducing round-trip carrier interference for certain DC commands. This time-division sending and receiving would be even more advantageous if it did not compromise the circuitry of the maintenance base station, the surface cleaning device, or the communication between the base station and the surface cleaning device. Typically, the communication between the maintenance base station and the surface cleaning device may be high-frequency, non-continuous communication; therefore, this example provides a simple yet effective scheduling mechanism to schedule DC information and communication information (e.g., these communication messages may command the surface cleaning device's brush motor to perform drive and reverse drive, drive rate, vacuum device to perform start and stop, base station heater to perform start and stop, base station fan to perform start and stop, and DC charging voltage levels, etc.) on the controller 200 of the maintenance base station 101 and the surface cleaning device 102.

[0034] like Figure 2 As shown, the maintenance base station 101 includes a controller 200, which may include a processor 201. In some embodiments, the processor 201 may be, but is not limited to, a digital signal processor, an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), a microprocessor, a microcontroller, etc. The processor 201 is connected to one or more communication chips 203 and a memory 202. Furthermore, the processor 201 may include a driver for transmitting signals to the memory 202 and another driver for transmitting signals to the communication chip 203. A power system 205 provides a power supply voltage to the processor 201 and provides one or more power supply voltages to the memory 202 and / or the communication chip 203. In some embodiments, more than one instance of the processor 201 may be included.

[0035] The processor 201 is connected to the communication chip 203 and the memory 202. In some cases, the memory 202 may be configured to store program instructions that can be executed by the processor 201. The processor 201 may include a driver for transmitting control signals to the memory 202 and another driver for transmitting signals to the communication chip 203.

[0036] The communication chip 203 can include required communication integrated circuits. In one embodiment, the communication chip 203 can implement a local communication interface.

[0037] In one example, the controller 200 assigns a first priority to a first type of data message to be communicated over the power line communication channel (e.g., direct current charging of the surface cleaning device). Further, the controller 200 can be configured to assign a second priority to a second type of data message to be communicated over the power line communication channel (e.g., communication information, e.g., that can command the brushroll motor to perform drive and reverse drive, drive rate, the vacuuming device to perform start and stop, the base station heater to perform on and off, the base station blower to perform on and off, etc.), the second priority being higher than the first priority.

[0038] In another example, the controller 200 stops initiating further communication of the direct current information responsive to a determination that at least one communication information having the second priority is queued for communication, the direct current information and the communication information being communicated in a time-division manner. The controller 200 is further configured to communicate at least one communication information having the second priority responsive to a determination that the power line communication channel is available. In a further example, the controller 200 is configured to restart or resume further communication of the direct current information responsive to a determination that at least one communication information having the second priority has been communicated and responsive to a determination that the communication channel is available.

[0039] In another example, determining that the power line communication channel is available can include waiting for an active communication of the communication information having the second priority to complete prior to communicating at least one direct current information having the first priority. Stopping initiating further communication of the direct current information can further include can further include stopping transmission of the direct current information having the first priority; or, stopping responding to the direct current information having the first priority at the controller on the surface cleaning device.

[0040] In another example, determining that the power line communication channel is available can include completing transmission of the communication information having the second priority at the same time as communication of the at least one direct current information having the first priority. The direct current information can be modulated according to a software modulation scheme selected to minimize channel occupancy of the direct current information for efficiency purposes, such that the communication information can be communicated at a higher frequency on a continuous basis of efficient direct current charging.

[0041] Figure 3 is a circuit block diagram that implements a communication scheduling process between the base station 101 and the surface cleaning device 102 according to some examples, and more specifically shows the communication scheduling system of the present disclosure.

[0042] The charging circuit of the maintenance base station 101 includes a charging loop 103 comprising a positive terminal 104 and a negative terminal 105 for interfacing with the charging terminals (positive terminal 104' and negative terminal 105') of the surface cleaning device.

[0043] The charging loop 103 includes a communication module and a charging module connected in parallel with the positive terminal 104, both of which are connected with the controller 200 of the maintenance base station to provide charging current information and transmit communication information to the surface cleaning device through the positive terminal 104. In one example, the base station receives communication information from the surface cleaning device through the positive terminal 104. The circuit switch 106 and the communication chip 203 are both connected with the controller 200; the circuit switch 106 is configured to be turned on and off according to the control signal of the processor 200 to cut off and connect the communication signal between the positive terminal 104 and the communication chip 203, so as to determine the priority of communication between the direct current information and the communication information.

[0044] Bidirectional communication between the communication chip 203 and the controller 200 to pass the communication signal from the surface cleaning device to the controller 200 through the communication chip 203, or pass the communication signal to the surface cleaning device through the communication chip 203 to the positive terminal. The integrated circuit of the communication chip 203 can include any required circuit depending on the type of power line communication system. For example, in one example, the communication chip 203 can implement a local communication interface and include devices for various types of line communication.

[0045] In some cases, in some examples, the priority allocation of direct current or communication is implemented by a circuit. As Figure 3 As shown, the base station includes a switch circuit 106 and a resistance circuit 107 in parallel with the positive terminal 104. Specifically, one end of the switch circuit 106 is electrically connected with the positive terminal 104, and the other end of the switch circuit 106 is electrically connected with the power supply control system 207 of the base station for turning on or off the current of the power supply control system 207 and the positive terminal 104. One end of the resistance circuit 107 is electrically connected with the positive terminal 104, and the other end of the resistance circuit 107 is electrically connected with the communication chip 203, so as to form a communication link between the positive terminal 104 and the communication chip 203 through the resistance circuit 107 when the switch circuit 106 is turned off.

[0046] In some examples, as Figure 3 As shown, the communication chip 203 is connected with the controller 200 through a bidirectional communication link to transmit the communication signal to the positive terminal 104 through the communication chip 203, or transmit the communication signal to the controller 200 through the communication chip 203.

[0047] The power system 205 provides a power voltage for the base station and one or more power voltages for the controller 200, the switching circuit 106, and / or the communication chip. The power system 205 includes a household AC power interface 206 connected thereto and a power control system 207 that provides a charging voltage for the surface cleaning device and powers the system.

[0048] The controller 200 has a function for determining the priority of the DC information and the communication information. Based on this priority determination, the controller 200 generates a corresponding control signal and sends the signal to the switching circuit 106. Specifically, when the controller 200 determines that the priority of the DC information is higher than the communication information, it sends an instruction to turn on the switching circuit 106.

[0049] In this case, the switching circuit 106 being turned on causes the parallel resistor circuit 107 connected thereto to form a resistive effect, thereby forming a path between the power system 205 and the positive terminal 104. In this way, the DC information will be preferentially transmitted through the power system 205 and sent to the positive terminal 104 through the closed switching circuit 106. This process enables the charging operation from the base station to the surface cleaning device.

[0050] However, in some embodiments, if the controller 200 determines that the priority of the communication information is higher than the DC information, it sends a different control signal to turn off the on state of the switching circuit 106. At this time, the switching circuit 106 turns off the conduction path, and the resistor circuit 107 connected in parallel thereto will form a new path between the communication chip 203 and the positive terminal 104. In this case, a communication link is established between the controller 200 and the positive terminal 104 through the communication chip 203. This connection allows the communication signals between the base station and the surface cleaning device to begin to be transmitted, thereby enabling data exchange and the transmission of control instructions.

[0051] Figure 3 A charging circuit 103' of a surface cleaning device that implements a communication scheduling process between the base station 101 and the surface cleaning device 102 is also shown according to some embodiments. In some embodiments, the controller 200' includes a processor, which can be a digital signal processor, an application specific integrated circuit, a field programmable gate array, a microprocessor, a microcontroller, or the like. In addition, the charging circuit 103' can include a communication chip 203' for transmitting signals to and receiving signals from the positive terminal 104'. In one example, the communication chip 203' of the surface cleaning device 102 and the communication chip 203 of the base station 101 can be the same chip.

[0052] As Figure 3As shown, the charging circuit 103' includes a system power supply 205' that provides a voltage to the operational components of the surface cleaning apparatus 102 and one or more supply voltages to the controller 200' and / or the communication chip 203'.

[0053] The controller 200' includes a driver that transmits instructions to the system peripheral circuitry 206' connected to the system power supply 205'. The peripheral circuitry 206' can include any desired circuitry. For example, in one embodiment, the peripheral circuitry 206' can be a rechargeable battery of the surface cleaning apparatus to receive the DC information from the positive terminal 104' to effect charging. In another embodiment, the peripheral circuitry 206' can be various types of external power circuitry or an externally connected rechargeable battery.

[0054] Figure 4 is a circuit block diagram that implements a communication scheduling process between the base station 101 and the surface cleaning apparatus 102 according to another example. The circuit includes a charging circuit that includes a positive terminal and a negative terminal for interfacing with the charging terminals of the surface cleaning apparatus.

[0055] The charging circuit of the base station 101 includes a charging circuit 103 that includes a positive terminal 104 and a negative terminal 105 for interfacing with the charging terminals (positive terminal 104' and negative terminal 105') of the surface cleaning apparatus.

[0056] The charging circuit 103 includes a communication module and a charging module connected in parallel with the positive terminal 104, both of which are connected to the controller 200 of the base station to provide charging current information and transmit communication information to the surface cleaning apparatus through the positive terminal 104. In one example, the base station receives communication information from the surface cleaning apparatus through the positive terminal 104. A communication chip 203 is connected to the controller, and the communication chip 203 and the controller are in bidirectional communication to transmit communication signals from the surface cleaning apparatus to the controller through the communication chip 203 or to transmit communication signals to the surface cleaning apparatus through the communication chip 203 to the positive terminal. The integrated circuit of the communication chip 203 can include any desired circuitry depending on the type of power line communication system. In one example, the communication chip 203 can implement a local communication interface and include a power carrier communication chip for various types of wired communication, so that the execution circuit is omitted and the communication signal is transmitted synchronously by loading the communication signal on the DC signal through the communication chip 203.

[0057] The power system 205 provides power supply voltage for the base station and one or more power supply voltages for the controller 200 and / or the communication chip 203. The power system 205 includes a household AC power interface 206 connected thereto and a power control system 207 that provides charging voltage for the surface cleaning device and powers the system.

[0058] The mechanism for the scheduling scheme based on the communication chip 203 (203') in Figure 3 and 4 is explained below. The mechanism involves assigning different priorities and connection types for the DC information and the communication information. In one example, the DC information is assigned a low priority and the communication information can be given the highest priority and preempt any DC information or acknowledgement of DC information that has not been transmitted / detected.

[0059] From a communication mechanism perspective, the communication information and the DC information follow different paths of the protocol stack. In one example, the communication information can be scheduled for transmission by the scheduler as usual under normal conditions. In addition, a carrier sense multiple access with collision avoidance protocol can be implemented on the communication information to enable interoperability between power line communication devices in a hybrid system, where the power line communication devices can be configured according to different protocols.

[0060] In one example, the communication information can directly interact with the link layer, and thus, the communication information can preempt access to the channel. In other words, the communication information is given higher priority access to the power line communication channel than the DC information by the link layer.

[0061] In another example, the communication information can be transmitted using the highest modulation scheme available through orthogonal frequency division multiplexing to accommodate the information between the DC information and its response. If the highest modulation scheme is not available to transmit the information, the communication information is segmented into appropriate bytes at the link layer and transmitted using the best modulation scheme to reduce the channel occupancy by the power line communication physical layer for any single frame.

[0062] On the other hand, the communication information can also be transmitted using a more robust modulation scheme while meeting the delay requirement. In one example, orthogonal frequency division multiplexing can be included in the power line communication for handling the physical layer transmission over the power line communication channel.

[0063] In one example, the communication begins when the controller assigns a first priority to the communication message to be communicated over the power line communication channel. For example, the communication information can include operational communication information between the surface cleaning device and the base station. The information can be communicated in data packets.

[0064] When the controller assigns a second priority to the DC information, communication continues. For example, the DC information includes charging control information transmitted between the maintenance base and the surface cleaning device. In such an example, the first priority can be higher than the second priority, such that the communication information takes priority over the DC information.

[0065] The DC information and the communication information can be queued for transmission separately. In such an example, the communication can include stopping the initiation of further communication of the DC information in response to a determination that communication information has been queued. The cutting off of the DC information actively transmitting on the communication channel can be permitted, and in further examples, the response to the active DC information can also be stopped to support the communication message. Once the communication channel is determined to be available, the controller can transmit the communication information.

[0066] For example, the controller can wait a predetermined period of time after stopping the initiation of further communication information before transmitting the DC information. In one example, the predetermined period of time can be selected based on the length of the data packet or time slot assigned to the transmission of the communication information.

[0067] In further examples, the communication information can be reinitiated in response to a determination that the channel is available after the transmission of the DC information.

[0068] The following illustrates an example of the transmission of the DC information 501 and the communication information 502 in various scenarios to meet the transmission requirements. The time interval for the transmission of the DC information 501 can be used for the communication of the communication information 502, as shown. Figure 5A In such an example, however, the frame duration of the communication information 502 can be limited in order to meet the round trip delay requirements. For example, the communication information 502 can be received within a short period of time between the DC information 501 and the corresponding surface cleaning device response.

[0069] In other examples, the priority of the DC information 501 over the surface cleaning device response can be higher than the communication information 502 that has not yet been transmitted. For example, if the DC information 501 is currently being transmitted, the communication information 502 can need to wait for a small period of time until the DC information transmission and response are complete. In another example, a degree of synchronization can be performed between the transmission of the DC information 501 and the communication information 502 to ensure that the round trip delay requirements are met. For example, the DC information 501 can be generated only at the end of a frame, such that no delay is introduced in the transmission of the initial DC information. The maintenance base 101 can monitor the ongoing communication information 502 and use this information to generate the DC information 501 only after the ongoing communication information 502 transmission is complete.

[0070] In further examples, the DC information 501 can even be given a higher priority than the acknowledgement information for the ongoing communication information 502. For example, the link layer can continue transmission of the ongoing communication information 502, but cut off the corresponding acknowledgement messages to provide access for transmission of the DC information 501. Thus, the DC information can gain priority access even before the acknowledgement information is sent.

[0071] In some examples, the DC information 501 and the communication information 502 are parallel in priority to meet the transmission requirements. The communication of the communication information 502 can be performed concurrently with the transmission of the DC information 501, as shown in Figure 5B In such examples, the frame duration of the communication information 502 can not be limited. For example, the communication information 502 can be sent and received during any communication period in which the maintenance base station and the surface cleaning device are responsive to the DC information 501.

[0072] In another example, a certain degree of time difference can also be performed between the transmission of the DC information 501 and the communication information 502 on the same channel to ensure that the round trip delay requirements are met. For example, the communication information 502 can only be generated at the end of the DC information 501 frame, so that no delay is generated when the initial communication information is transmitted. The maintenance base station 101 can monitor the ongoing communication information 502 and use this information to only generate the communication information 502 after the ongoing DC information 502 frame transmission is completed.

[0073] In other examples, the priority of the DC information 501 or the surface cleaning device response is the same as the communication information 502 that has not yet been transmitted. For example, if the DC information 501 is currently being transmitted, the communication information 502 transmission and the DC information 501 transmission are performed in parallel on the same channel.

[0074] Figure 6 is an example schematic diagram of components of a controller 200' of a surface cleaning device. According to some aspects of the present disclosure, in conjunction with Figure 3 and 4 The controller 200' is electrically connected with a charging circuit 103' that includes a positive terminal 104' and a negative terminal 105' for interfacing with the positive terminal 104 and the negative terminal 105 of a base station of the surface cleaning device;

[0075] The charging circuit 103' includes a communication module and a charging module connected with the positive terminal 104' to receive a charging current and transmitted communication control signals from the base station through the positive terminal 104' and to transmit control signals to the base station through the positive terminal 104'.

[0076] In one example, the communication module of the surface cleaning device can include a communication chip 203' identical to the maintenance base station, and bidirectional communication between the communication chip 203' and the controller 200', the communication chip 203' is electrically connected to the positive terminal 104' to transmit a first control signal to the controller 200' through the communication chip 203', or transmit a control signal to the positive terminal 104' through the communication chip 203'.

[0077] In one example, the surface cleaning device includes a power system 205' connected to the controller 200', the power system 205' can be connected to a rechargeable battery to adjust the charging voltage to the rechargeable battery according to the voltage adjustment signal of the controller received by the positive terminal, and power supply to the functional components of the surface cleaning device according to the power consumption information.

[0078] The controller 200' is programmed to take action according to the received signal, and in appropriate cases, apply control signals to control elements. The controller 200' can be a simple hardwired circuit that linearly responds to the input dirt sensor signal to apply control signals to the control elements. Alternatively, the controller 200' can be a hardwired circuit or a processor that, through programming, outputs signals to control elements that are some function of the communication input signals received from the base station. The controller 200' is electrically connected to the speed controller for the vacuum motor. The controller 200' is also electrically connected to the speed controller for the brush roll drive motor, so as to initiate control of at least one of the above components based on the communication information to achieve self-cleaning.

[0079] In any case, the controller 200' outputs control signals to control elements based on received signals. For example, in an example of the present disclosure, a processor can compare the value of a signal received from a maintenance base station to a data threshold in memory and generate a control signal for adjusting the speed of a vacuum motor or the speed of a brush roll motor or both to match the level of dirt detected in the surface to be cleaned. The controller 200' applies control signals to the speed controller based on selected operating instructions and in response to input signals received from the dirt sensor. The speed controller provides a standard feedback loop to the controller 200' to determine when the motor has reached the desired speed. The controller 200' is programmed to compare feedback signals from the speed controller to the control signal and continue to apply the control signal to the speed controller until the motor reaches the desired speed.

For example, output component 260' can include a receiver, a transmitter, a transceiver, a modem, a network interface card, and / or an antenna through which output component 260' sends and receives signals to and from control elements.

[0084] For example, according to one example of the present disclosure, the output component 260' can be in two-way communication with a speed controller of a first variable speed motor associated with the motorized vacuum source to transmit a communication control signal to the speed controller for controlling the speed of the first variable speed motor during a maintenance action of the surface cleaning device on the base station. According to one example of the present disclosure, the output component 260' can be in two-way communication with a speed controller of a second variable speed motor associated with the agitator to transmit a communication control signal to the speed controller for controlling the speed of the second variable speed motor during a maintenance action of the surface cleaning device on the base station.
