Abstract

The application relates to the technical field of smart homes, in particular to a dust collection base station control method and a dust collection base station. The method comprises the following steps: if the dust collection base station meets dust collection conditions, a fan is controlled to work in a first suction mode until it is detected that the dust collection base station meets preset operation conditions, then the fan is controlled to work in a second suction mode, the average suction of the second suction mode is greater than that of the first suction mode, and the average working power of the second suction mode is greater than that of the first suction mode. When dust collection starts, the fan is controlled to work in the first suction mode with small power, so that high noise caused by the start of the fan is reduced, the problem that the circuit device of the fan is damaged due to the fact that a large driving current is suddenly poured into the fan at the start is avoided, and the service life of the fan is prolonged. When the dust collection base station meets the preset operation conditions, the fan is controlled again in the second suction mode with large power, so that the garbage collection efficiency can be improved.

Description

Technical Field

[0001] This invention relates to the field of smart home technology, specifically to a control method for a dust collection base station and a dust collection base station. Background Technology

[0002] With the development of smart home technology, robotic vacuum cleaners and dustbins are increasingly common in households. The vacuum cleaner collects household debris, and when full, it automatically navigates to and docks with the dustbin. The dustbin then activates its fan, which provides vacuum suction to draw the debris from the vacuum cleaner into the dust collection chamber at the dust collection station. However, current technologies suggest that when the dustbin is in dust collection mode, it uses a relatively high rated power to drive the fan, resulting in significant noise pollution for the user. Summary of the Invention

[0003] One objective of this invention is to provide a control method and a dust collection base station, aiming to solve the technical problem that dust collection bins in related technologies generate significant noise during dust collection.

[0004] In a first aspect, embodiments of the present invention provide a control method for a dust collection base station. The dust collection base station includes a fan, which provides vacuum suction to draw debris from a cleaning device into the dust collection chamber of the dust collection base station. The method includes the following steps: when the dust collection base station is connected to the cleaning device, it is detected whether the dust collection base station meets the dust collection conditions. If so, the fan is controlled to operate in a first suction mode until the dust collection base station is detected to meet preset operating conditions. Then, the fan is controlled to operate in a second suction mode. The average suction power of the fan in the second suction mode is greater than that in the first suction mode, and the average operating power of the fan in the second suction mode is greater than that in the first suction mode.

[0005] Optionally, the fan operates for less than or equal to 2 seconds in the first suction mode, and operates for more than or equal to 10 seconds in the second suction mode.

[0006] Optionally, the fan's operating power supply is an AC power supply with an AC cycle. In the first suction mode, the average operating power of the fan corresponding to the AC cycle is positively correlated with the fan's operating time.

[0007] Optionally, controlling the fan to operate in the first suction mode includes:

[0008] Increase the average working power corresponding to the AC cycle sequentially according to the cycle order.

[0009] The fan operation is controlled based on the average operating power corresponding to the AC cycle.

[0010] Optionally, the maximum average operating power of the fan in the first suction mode is equal to the average operating power of the fan in the second suction mode.

[0011] Optionally, the maximum suction power of the fan in the first suction mode is equal to the average suction power of the fan in the second suction mode.

[0012] Optionally, the AC operating cycle of the fan includes a first half-cycle and a second half-cycle that are continuous in time and opposite in polarity. Controlling the fan operation based on the average operating power corresponding to the AC cycle includes:

[0013] When the first zero-crossing point of the first half-cycle is detected, a delay of a specified duration is applied, during which the fan is in a power-off state.

[0014] After a specified period of time, the control fan will operate for half the fan's operating time until the second zero crossing point of the first half-cycle is reached, at which point the fan will be de-energized.

[0015] When the third zero-crossing point of the second half-cycle is detected, a delay of a specified duration is applied, during which the fan is in a power-off state.

[0016] After a specified period, the control fan operates for half the fan's operating time until the fourth zero crossing of the second half-cycle is reached, at which point the fan is de-energized.

[0017] Optionally, when the dust collection base station is detected to meet preset operating conditions, controlling the fan to operate in the second suction mode includes:

[0018] When the average operating power of the fan increases to the maximum average operating power, it is determined that the dust collection base station meets the preset operating conditions.

[0019] Control the fan to operate in the second suction mode.

[0020] Optionally, when the dust collection base station is detected to meet preset operating conditions, controlling the fan to operate in the second suction mode includes:

[0021] Determine the pressure difference of the dust collection base station, which is the difference between the preset reference atmospheric pressure and the air pressure in the dust collection chamber of the dust collection base station;

[0022] If the pressure difference meets the first preset negative pressure threshold condition, then the dust collection base station is determined to meet the preset operating conditions.

[0023] Control the fan to operate in the second suction mode.

[0024] Optionally, controlling the fan to operate in the first suction mode includes:

[0025] The air duct of the dust collection base station is controlled to enter the closed state. When the air duct is in the closed state, garbage cannot enter the dust collection chamber of the dust collection base station through the air duct.

[0026] The fan operates for a first preset duration based on a preset reference average operating power, where the reference average operating power is less than the average operating power of the second suction mode.

[0027] Optionally, controlling the fan to operate in the second suction mode includes:

[0028] The air duct of the dust collection base station is controlled to enter the open state. When the air duct is in the open state, the garbage can enter the dust collection chamber of the dust collection base station through the air duct.

[0029] The fan operates for a second preset duration based on the preset rated power.

[0030] In a second aspect, embodiments of the present invention provide a non-volatile readable storage medium storing computer-executable instructions for causing a dust collection base station to perform the aforementioned control method for a dust collection base station.

[0031] In a third aspect, embodiments of the present invention provide a dust collection base station, comprising:

[0032] At least one processor; and,

[0033] A memory communicatively connected to the at least one processor; wherein,

[0034] The memory stores instructions that can be executed by the at least one processor, which, when executed by the at least one processor, enables the at least one processor to perform the aforementioned control method for the dust collection base station.

[0035] In the control method of the dust collection base station provided in this embodiment of the invention, when the dust collection base station is connected to the cleaning equipment, it is detected whether the dust collection base station meets the dust collection conditions. If so, the fan is controlled to work in the first suction mode until the dust collection base station is detected to meet the preset operating conditions. Then, the fan is controlled to work in the second suction mode. The average suction power of the fan in the second suction mode is greater than that in the first suction mode, and the average operating power of the fan in the second suction mode is greater than that in the first suction mode. When dust collection begins, this embodiment uses the low-power first suction mode to control the fan, thus reducing the high noise generated when the fan starts working. It also avoids the problem of damaging the fan's circuit components due to the large instantaneous drive current injected into the fan during startup, which is beneficial to improving the service life of the fan. When the dust collection base station meets the preset operating conditions, this embodiment then uses the high-power second suction mode to control the fan, thus improving the waste collection efficiency. Therefore, this embodiment can achieve a balance between low noise and efficiency, ensuring both reduced fan noise and service life, and ensuring that the dust collection base station has high waste collection efficiency.

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0046] It should be noted that, unless otherwise specified, the various features in the embodiments of this invention can be combined with each other, all of which are within the protection scope of this invention. Furthermore, although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than the module division in the device or the order in the flowchart. Moreover, the terms "first," "second," and "third" used in this invention do not limit the data or execution order, but only distinguish identical or similar items with essentially the same function and effect.

[0047] This invention provides a dust collection base station, which not only supports dust collection power, but also supports charging or disinfection functions.

[0048] Please refer to the following: Figure 1 and Figure 2 The dust collection base station 100 includes a base station body 11, a dust collection chamber 12, an air duct 13, a fan 14, a power module 15, and a control circuit 16.

[0049] The base station body 11 is used to carry the various components of the dust collection base station 100.

[0050] The dust collection chamber 12 is installed inside the base station body 11 and is used to collect garbage. The dust collection chamber 12 can be a box structure or a dust bag.

[0051] The air duct 13 is installed inside the base station body 11. One end of the air duct 13 is located on the dust collection chamber 12, and the other end of the air duct 13 is used to connect to the external environment. When the cleaning equipment is connected to the dust collection base station, the other end of the air duct 13 is connected to the waste discharge outlet of the cleaning equipment 200, and the waste from the cleaning equipment can enter the dust collection chamber 12 of the dust collection base station 100 through the air duct 13. The cleaning equipment can be a sweeper, mop, sweeper-mop combo, floor scrubber, etc.

[0052] A fan 14 is installed inside the base station body 11. The dust collection chamber 12 has a fan outlet, and the fan 14 is mounted on the fan outlet. The fan 14 provides vacuum suction to draw debris from the cleaning equipment into the dust collection chamber 12 of the dust collection base station 100. The fan 14 draws air from the dust collection chamber 12 and expels it to the outside. As a result, the air pressure inside the dust collection chamber 12 is lower than the external atmospheric pressure, creating a negative pressure state inside the dust collection chamber 12. The external atmospheric pressure can then draw debris from the cleaning equipment into the dust collection chamber 12 through the air duct 13.

[0053] The power module 15 can provide operating power to the fan 14, and the operating power can be AC ​​power.

[0054] The control circuit 16 is electrically connected to the fan 14 and the power module 15 respectively, and is used to control the operation of the fan 14.

[0055] Please see Figure 3 The control circuit 16 includes a zero-crossing detection circuit 161, a switching circuit 162, and a controller 163. The zero-crossing detection circuit 161 is electrically connected to the power module 15 and is used to detect the zero-crossing point of the AC power supply. The switching circuit 162 is located between the power module 15 and the fan 14. The controller 163 is electrically connected to the zero-crossing detection circuit 161, the switching circuit 162, the fan 14, and the power module 15.

[0056] When the zero-crossing detection circuit 161 detects the zero-crossing point of the AC power supply, the zero-crossing detection circuit 161 sends a zero-crossing detection signal to the controller 163, and the controller 163 executes relevant business logic according to the zero-crossing detection signal.

[0057] In some embodiments, when the controller 163 receives a first zero-crossing detection signal, the controller 163 starts timing. When the timing time equals a specified duration, the controller 163 controls the switching circuit 162 to enter the conducting state, and the AC power output from the power module 15 can be applied to the fan 14 through the switching circuit 162 to make the fan 14 work. Then, when the controller 163 receives a second zero-crossing detection signal, the controller 163 controls the switching circuit to enter the cut-off state, and the AC power output from the power module 15 cannot be applied to the fan 14 through the switching circuit 162. The fan 14 is in a power-off state. Simultaneously, the controller 163 restarts timing. When the timing time equals a specified duration, the controller 163 controls the switching circuit 162 to enter the conducting state, and the AC power output from the power module 15 can be applied to the fan 14 through the switching circuit 162 to make the fan 14 work.

[0058] In some embodiments, when the switching circuit 162 is a bidirectional thyristor, when the controller 163 receives a zero-crossing detection signal, the controller 163 starts timing. When the timing time equals a specified duration, the controller 163 sends a high-level signal to the trigger terminal of the bidirectional thyristor, causing the bidirectional thyristor to enter the conducting state. The AC power output from the power module 15 can be applied to the fan 14 through the switching circuit 162 to make the fan 14 work. When the timing time equals a preset off time, the controller 163 sends a low-level signal to the trigger terminal of the bidirectional thyristor. Since the voltage across the anode and cathode of the bidirectional thyristor still exists, the bidirectional thyristor remains in the conducting state, and the AC power output from the power module 15 can still be applied to the fan 14 through the switching circuit 162 to make the fan 14 work. When the zero point of the AC power is reached, since the voltage across the anode and cathode of the bidirectional thyristor does not exist, the bidirectional thyristor enters the off state. The preset off time is greater than the specified duration, for example, the specified duration is 8.9 ms and the preset off time is 9 ms.

[0059] Please see Figure 4The dust collection base station 100 also includes a duct switch 17, which is mounted on the duct 13 and electrically connected to the control circuit 16. The duct switch 17 is controlled by the control circuit 16 and operates in an open or closed state. When the duct switch 17 is in the open state, waste can enter the dust collection chamber 12 through the duct 13. When the duct switch 17 is in the closed state, waste cannot enter the dust collection chamber 12 through the duct 13. The duct switch 17 can be a solenoid valve.

[0060] As another aspect of this invention, this embodiment provides a control method for a dust collection base station. The dust collection base station includes a fan, which provides vacuum suction to draw debris from cleaning equipment into the dust collection chamber of the dust collection base station. Please refer to [link to relevant documentation]. Figure 5 The control method for dust collection base stations includes the following steps:

[0061] S51: When the dust collection base station is connected to the cleaning equipment, check whether the dust collection base station meets the dust collection conditions.

[0062] In this step, when the dust collection base station is connected to the cleaning equipment, the detection of whether the dust collection base station meets the dust collection conditions includes the following steps: obtaining a power-on signal, detecting whether the dust collection base station meets the initialization conditions based on the power-on signal, if the initialization conditions are met, detecting whether the dust collection base station is connected to the cleaning equipment, if the dust collection base station is connected to the cleaning equipment, detecting whether the dust collection base station meets the dust collection conditions, if the initialization conditions are not met, continuing to detect whether the dust collection base station meets the initialization conditions, if the dust collection base station is not connected to the cleaning equipment, continuing to detect whether the dust collection base station is connected to the cleaning equipment.

[0063] The process of detecting whether the dust collection base station meets the initialization conditions based on the power-on signal includes: responding to the power-on signal, controlling the dust collection base station to detect whether it has been connected to the cleaning equipment within a preset reference time. If not connected, the dust collection base station is determined to meet the initialization conditions. If connected, the first time the cleaning equipment last connected to the dust collection base station and the second time the cleaning equipment last left the dust collection base station are determined, and the time difference between the first and second times is calculated. Based on the time difference and a preset time difference threshold, the dust collection base station is then used to determine whether it meets the initialization conditions. The preset reference time can be customized by the designer based on engineering experience; for example, a preset reference time of 2 seconds.

[0064] Detecting whether a dust collection base station meets initialization conditions based on the time difference and a preset time difference threshold includes: determining whether the time difference is greater than the preset time difference threshold; if it is, the dust collection base station is determined to meet the initialization conditions; if not, the detection process continues. The preset time difference threshold can be customized by the designer based on engineering experience, for example, a preset time difference threshold of 5 minutes.

[0065] When the dust collection base station is powered on, if the cleaning equipment is detected to be in place within a preset reference time, the dust collection base station will not immediately enter the dust collection state in order to complete the initialization of the dust collection base station. In addition, in order to avoid the dust collection base station frequently performing dust collection operations on the cleaning equipment, the cleaning equipment needs to be away from the dust collection base station for at least a preset time difference threshold. Within a time period longer than the preset time threshold, it is generally assumed that the cleaning equipment has collected a lot of garbage. Once the dust collection base station confirms that the cleaning equipment is equipped with a dust collection device, it can start performing dust collection operations on the cleaning equipment.

[0066] The cleaning equipment is equipped with charging electrodes, and the dust collection base station is equipped with supply electrodes. The dust collection base station can detect the presence signal through the supply electrodes. When the charging electrodes are connected to the supply electrodes, the dust collection base station detects whether the cleaning equipment is connected to the dust collection base station based on the amplitude of the presence signal and a preset amplitude. If the amplitude of the presence signal is greater than the preset amplitude, it is determined that the cleaning equipment is connected to the dust collection base station; if the amplitude of the presence signal is less than the preset amplitude, it is determined that the cleaning equipment is not connected to the dust collection base station. For example, if the preset amplitude is 110, when the cleaning equipment is connected to the dust collection base station, the dust collection base station can detect an amplitude of approximately 400 for the presence signal through the supply electrodes. When the cleaning equipment is not connected to the dust collection base station or has poor contact, the amplitude of the presence signal detected by the dust collection base station through the supply electrodes is usually less than 110. Therefore, this embodiment can reliably detect whether the cleaning equipment is connected to the dust collection base station based on the amplitude of the presence signal and the preset amplitude.

[0067] The process of determining whether a dust collection base station meets the dust collection conditions includes: checking whether the dust collection device of the cleaning equipment is in place. If it is in place, the dust collection base station is determined to meet the dust collection conditions; if it is not in place, the dust collection base station is determined not to meet the dust collection conditions. The dust collection device of the cleaning equipment can be a dust box or a dust bag. When the dust collection base station meets the dust collection conditions, it performs the dust collection operation. When the dust collection base station does not meet the dust collection conditions, it must wait until the dust collection conditions are met before it can perform the dust collection operation.

[0068] S52: If yes, control the fan to work in the first suction mode until the dust collection station meets the preset operating conditions, then control the fan to work in the second suction mode. If no, return to step S51.

[0069] In this step, the average suction power of the fan in the second suction mode is greater than that in the first suction mode, and the average operating power of the fan in the second suction mode is also greater than that in the first suction mode. That is, the fan operating at its average operating power in the first suction mode will produce a first average suction power, and the fan operating at its average operating power in the second suction mode will produce a second average suction power. Since the average operating power of the first suction mode is less than that of the second suction mode, the first average suction power will be less than the second average suction power. Compared to the average operating power of the second suction mode, the average operating power of the first suction mode is low. When dust collection begins, this embodiment uses a low-power first suction mode to control the fan's operation. This reduces the high noise generated when the fan starts working and also avoids the problem of damaging the fan's circuit components due to a large instantaneous drive current during startup, thus improving the fan's service life.

[0070] The preset operating conditions are used to trigger the dust collection base station to switch from the first suction mode to the second suction mode. When the dust collection base station meets the preset operating conditions, it switches from the first suction mode to the second suction mode, using a higher average operating power to control the fan. In this embodiment, when the dust collection base station meets the preset operating conditions, the high-power second suction mode is then used to control the fan, thus improving waste collection efficiency. Therefore, this embodiment achieves a balance between low noise and efficiency, ensuring both reduced fan noise and lifespan while maintaining high waste collection efficiency at the dust collection base station.

[0071] In some embodiments, the operating time of the fan in the first suction mode is less than or equal to 2 seconds, and the operating time of the fan in the second suction mode is greater than or equal to 10 seconds. That is, the time of the fan's low-power slow start process is less than or equal to 2 seconds, and the time of the high-power process is greater than or equal to 10 seconds. In this embodiment, a shorter time is first allocated for the fan to start slowly, and then a longer time is provided to control the fan to work at high power, thereby ensuring effective garbage collection.

[0072] In some embodiments, the power supply for the fan is an AC power supply with an AC cycle. In the first suction mode, the average operating power of the fan in each AC cycle is positively correlated with the fan's operating time. The fan's operating time is the duration of operation of the fan in each AC cycle. The longer the fan's operating time, the higher the average operating power. Therefore, this embodiment can adjust the fan's operating time in each AC cycle in the first suction mode, thereby achieving the purpose of adjusting the fan's average operating power in each AC cycle.

[0073] In some embodiments, controlling the fan to operate in the first suction mode includes: sequentially increasing the average operating power corresponding to the AC cycle in a cyclical order, and controlling the fan to operate according to the average operating power corresponding to the AC cycle. Therefore, in the first suction mode, this embodiment can gradually increase the average operating power of the fan during the slow start-up process by sequentially increasing the average operating power corresponding to each AC cycle in a climbing manner. This avoids reaching the average operating power of the second suction mode too quickly, thus preventing premature start-up, and also improves the efficiency of garbage collection by increasing the average operating power during the slow start-up process.

[0074] Increasing the average operating power corresponding to the AC cycle in a sequential manner includes: increasing the fan operating time corresponding to the AC cycle in a sequential manner, where the fan operating time and operating power are positively correlated.

[0075] In some embodiments, the first suction mode includes n AC cycles, where the fan operating time t is the AC cycle Ti. i =t1+2*(i-1)Δt,t i ∝P i , t i Let t1 be the operating time of the i-th fan in the i-th AC cycle, t1 be the operating time of the first fan in the first AC cycle, Δt be the preset time difference, and P be the operating time of the i-th fan in the i-th AC cycle. i Let be the average operating power of the i-th AC cycle. For example, the operating time t1 of the first fan in the first AC cycle is 2.2 ms, and Δt is 0.1 ms; the operating time t2 of the second fan in the second AC cycle is 2.4 ms, and so on.

[0076] The alternating current cycle of a wind turbine consists of a first half-cycle and a second half-cycle that are continuous in time and opposite in polarity. When the first half-cycle is positive, the second half-cycle is negative. When the first half-cycle is negative, the second half-cycle is positive.

[0077] In some embodiments, controlling the operation of the fan according to the average operating power corresponding to the AC cycle includes the following steps: controlling the fan operation for the duration of the fan operation corresponding to the AC cycle during the first half-cycle.

[0078] In some embodiments, controlling the operation of the fan according to the average operating power corresponding to the AC cycle includes the following steps: controlling the fan operation during the second half-cycle for the fan operation duration corresponding to the AC cycle.

[0079] For example, when the controller receives a zero-crossing detection signal in the first or second half-cycle, the controller starts timing. When the timing time equals the specified duration, the controller controls the switching circuit to enter the conducting state and controls the switching circuit to continue conducting according to the working duration of the fan. The AC power output from the power module can be applied to the fan through the switching circuit so that the fan can work according to the working duration of the fan.

[0080] In some embodiments, controlling the operation of the fan according to the average operating power corresponding to the AC cycle includes the following steps: when the first zero-crossing point of the first half-cycle is detected, a delay of a specified duration is made, wherein the fan is in a power-off state during the specified duration; after the specified duration, the fan is controlled to operate for 1 / 2 of the fan operating time until the second zero-crossing point of the first half-cycle is reached, at which point the fan is in a power-off state; when the third zero-crossing point of the second half-cycle is detected, a delay of a specified duration is made, wherein the fan is in a power-off state during the specified duration; after the specified duration, the fan is controlled to operate for 1 / 2 of the fan operating time until the fourth zero-crossing point of the second half-cycle is reached, at which point the fan is in a power-off state.

[0081] In some embodiments, the specified duration is equal to the difference between 1 / 2 of the AC cycle and 1 / 2 of the fan operating time.

[0082] Since the fan operates on AC power, the zero-crossing detection circuit detects the zero-crossing points during the alternation of the positive and negative half-cycles and generates a zero-crossing detection signal. When the AC power transitions from the positive to the negative half-cycle, the zero-crossing detection signal is a low-level signal; the falling edge of this low-level signal indicates the start of the negative half-cycle. When the AC power transitions from the negative to the positive half-cycle, the zero-crossing detection signal is a high-level signal; the rising edge of this high-level signal indicates the start of the positive half-cycle. Taking AC mains power as an example, the frequency of AC mains power is 50Hz, the period of the positive half-cycle is 10ms, the period of the negative half-cycle is 10ms, and a complete AC cycle is 20ms.

[0083] Please see Figure 6 , Figure 6 The waveform diagram for three AC cycles is shown. (Example) Figure 6 As shown:

[0084] For the first communication cycle:

[0085] When the first zero-crossing point of the positive half-cycle is detected, this embodiment records the current time as T0, and starts the fan after a specified delay of Tt. Assuming the specified delay Tt is 8.9ms, that is, the current time when the fan starts working is T1 = T0 + 8.9ms.

[0086] Since the period of the positive half-cycle is 10ms, the second zero-crossing point of the positive half-cycle will arrive at the current time T1' = T0 + 10ms. When the second zero-crossing point of the positive half-cycle arrives, the fan is in a power-off state. Therefore, the fan's operating time in the positive half-cycle is 1.1ms.

[0087] In addition, in this embodiment, M=1.

[0088] Next, the third zero-crossing point of the negative half-cycle arrives and is detected by the zero-crossing detection circuit. Therefore, in this embodiment, the current time is recorded as T0, and the fan starts operating after a specified delay. Since the period of the negative half-cycle is 10ms, the fourth zero-crossing point of the negative half-cycle will arrive at the current time T1” = T0 + 10 + 10ms. When the fourth zero-crossing point of the negative half-cycle arrives, the fan is in a power-off state. Therefore, the fan's operating time in the negative half-cycle is 1.1ms. In this embodiment, M = 1 + 1 = 2. Since M equals 2, this embodiment resets M to zero.

[0089] Overall, the operating time of the wind turbine in the first AC cycle is equal to 2 * 1.1 = 2.2 ms.

[0090] For the second communication cycle:

[0091] First, in this embodiment, the working time of the fan in the second AC cycle is determined to be 2.4ms.

[0092] The specified duration is equal to the difference between 1 / 2 20ms and 1 / 2 2.4, which is 8.8ms.

[0093] When the first zero-crossing of the positive half-cycle is detected, this embodiment records the current time as T0. After a specified delay of Tt (8.8 ms), the fan starts operating. That is, the current time when the fan starts operating is T1 = T0 + 8.8 ms. When the second zero-crossing of the positive half-cycle arrives, the fan is in a power-off state. Therefore, the fan operating time in the positive half-cycle is 1.2 ms.

[0094] Next, the third zero-crossing point of the negative half-cycle arrives and is detected by the zero-crossing detection circuit. Therefore, in this embodiment, the current time is recorded as T0, and the fan starts operating after a specified delay. Since the period of the negative half-cycle is 10ms, the fourth zero-crossing point of the negative half-cycle will arrive at the current time T1” = T0 + 10 + 10ms. When the fourth zero-crossing point of the negative half-cycle arrives, the fan is in a power-off state. Therefore, the fan's operating time in the negative half-cycle is 1.2ms.

[0095] Overall, the operating time of the fan in the second AC cycle is equal to 2 * 1.2 = 2.4 ms.

[0096] For the third communication cycle:

[0097] First, in this embodiment, the operating time of the fan in the third AC cycle is determined to be 2.6ms.

[0098] The specified duration is equal to the difference between 1 / 2 20ms and 1 / 2 2.6, which is 8.7ms.

[0099] When the first zero-crossing of the positive half-cycle is detected, this embodiment records the current time as T0. After a specified delay of Tt (8.7ms), the fan starts operating. That is, the current time when the fan starts operating is T1 = T0 + 8.7ms. When the second zero-crossing of the positive half-cycle arrives, the fan is in a power-off state. Therefore, the fan operating time in the positive half-cycle is 1.3ms.

[0100] Next, the third zero-crossing point of the negative half-cycle arrives and is detected by the zero-crossing detection circuit. Therefore, in this embodiment, the current time is recorded as T0, and the fan starts operating after a specified delay. Since the period of the negative half-cycle is 10ms, the fourth zero-crossing point of the negative half-cycle will arrive at the current time T1” = T0 + 10 + 10ms. When the fourth zero-crossing point of the negative half-cycle arrives, the fan is in a power-off state. Therefore, the fan's operating time in the negative half-cycle is 1.3ms.

[0101] Overall, the operating time of the fan in the third AC cycle is equal to 2 * 1.3 = 2.6 ms.

[0102] And so on, without going into detail here.

[0103] This embodiment can sequentially extend the working time of the fan in each AC cycle, smoothly control the continuous increase of the average working power of the fan, which is beneficial to improving the working stability and reliability of the fan, and can also improve the suction power of the collection with low noise, thereby improving the waste collection efficiency.

[0104] In addition, by Figure 6 It can be seen that the working time of the fan in the 90th AC cycle of the dust collection base station is equal to 20ms. That is, the working time of the fan in the 90th AC cycle is the duration of the AC cycle. At this time, the dust collection base station controls the fan to work at the maximum average working power. It can also be seen that the time taken for the fan to start slowly is 90*20ms=1.8s. It can also be seen that this embodiment can gradually increase the average working power to the average working power of the second suction mode in the first suction mode, avoiding damage to the fan caused by factors such as surge current caused by power jump.

[0105] In some embodiments, the maximum average operating power of the fan in the first suction mode is equal to the average operating power of the fan in the second suction mode. This embodiment can gradually increase the average operating power to the maximum average operating power in the first suction mode, which is equal to the average operating power in the second suction mode. This allows the average operating power of the first suction mode to transition effectively to the average operating power of the second suction mode, enabling the fan to smoothly and seamlessly switch to the average operating power of the second suction mode. In some embodiments, the average operating power of the second suction mode is a preset rated power.

[0106] In some embodiments, the maximum suction power of the fan in the first suction mode is equal to the average suction power of the fan in the second suction mode. As mentioned above, this embodiment can gradually increase the suction power to the maximum suction power in the first suction mode, and the maximum suction power is equal to the average suction power in the second suction mode. This allows the suction power of the first suction mode to transition effectively to the suction power of the second suction mode, enabling the fan to smoothly and seamlessly switch to the suction power of the second suction mode for operation. In some embodiments, the average suction power of the second suction mode is a preset rated suction power.

[0107] In some embodiments, when the dust collection base station is detected to meet the preset operating conditions, controlling the fan to operate in the second suction mode includes: when the average operating power of the fan increases to the maximum average operating power, it is determined that the dust collection base station meets the preset operating conditions, and the fan is controlled to operate in the second suction mode. As mentioned above, in the first suction mode, this embodiment can gradually increase the average operating power to the maximum average operating power of the second suction mode, avoiding damage to the fan caused by factors such as surge current caused by power jumps, and then it can be switched to the second suction mode for operation.

[0108] In some embodiments, when the fan switches from a first suction mode to a second suction mode, the maximum average operating power of the fan in the first suction mode does not need to be equal to the average operating power in the second suction mode. Controlling the fan to operate in the second suction mode when the dust collection base station meets preset operating conditions includes: determining the pressure difference of the dust collection base station, where the pressure difference is the difference between a preset reference atmospheric pressure and the air pressure in the dust collection chamber of the dust collection base station; if the pressure difference meets a first preset negative pressure threshold condition, then it is determined that the dust collection base station meets the preset operating conditions, and the fan is controlled to operate in the second suction mode.

[0109] This embodiment continuously monitors the pressure difference at the dust collection station during the slow start-up of the fan, and controls whether the dust collection station needs to control the fan in the second suction mode based on the pressure difference. Compared to using the average operating power of the first suction mode as the trigger condition for entering the second suction mode, which varies due to differences in the shape, airtightness, and service life of various dust collection stations leading to variations in the air filling volume of the dust collection chamber, this embodiment uses pressure difference as the trigger condition. The pressure difference can reflect the current situation of the dust collection chamber in real time, and the pressure difference acts directly on the waste. When the pressure difference meets the predetermined first preset negative pressure threshold, it indicates that the dust collection station can switch to the second suction mode with a higher operating power to control the fan. This ensures both low-noise operation and no reduction in waste collection efficiency.

[0110] Whether the pressure difference meets the first preset negative pressure threshold condition includes: determining whether the pressure difference is greater than the first preset negative pressure threshold. If it is greater, the first preset negative pressure threshold condition is met; if it is less, the first preset negative pressure threshold condition is not met.

[0111] In some embodiments, before determining the pressure difference of the dust collection base station, when detecting that the dust collection base station meets the preset operating conditions, controlling the fan to operate in the second suction mode further includes: when it is detected that the average operating power of the fan in the first suction mode is equal to a specified power, determining the pressure difference of the dust collection base station, wherein the specified power is less than the average operating power of the second suction mode, for example, the specified power is one-third of the average operating power of the second suction mode.

[0112] In some embodiments, controlling the fan to operate in a first suction mode includes the following steps: controlling the air duct of the dust collection base station to enter a closed state, wherein when the air duct is in the closed state, debris cannot enter the dust collection chamber of the dust collection base station through the air duct, and controlling the fan to operate for a first preset duration according to a preset reference average operating power. The reference average operating power is less than the average operating power of the second suction mode.

[0113] In this embodiment, the air duct is closed by switching off the air duct, putting the air duct into a closed state. At this time, the fan exhausts the air in the dust collection chamber of the dust collection base station to the external environment, but external garbage cannot enter the dust collection chamber through the air duct, and external air cannot enter the dust collection chamber through the air duct to fill the dust collection chamber. Therefore, the negative pressure in the dust collection chamber of the dust collection base station will increase rapidly, which is beneficial for quickly and efficiently collecting garbage when the second suction mode is entered later.

[0114] In some embodiments, when the dust collection base station is detected to meet the preset operating conditions, controlling the fan to operate in the second suction mode includes: determining the pressure difference of the dust collection bin, the pressure difference being the difference between the preset reference atmospheric pressure and the dust collection chamber air pressure of the dust collection bin; if the pressure difference meets the second preset negative pressure threshold condition, then it is determined that the dust collection bin meets the preset operating conditions; if the pressure difference does not meet the second preset negative pressure threshold condition, then the fan is controlled to operate for a first preset duration according to the preset reference average operating power, wherein the first preset duration is customized by the designer based on engineering experience.

[0115] Whether the pressure difference meets the second preset negative pressure threshold condition includes: determining whether the pressure difference is greater than the second preset negative pressure threshold. If it is greater, the predetermined second preset negative pressure threshold condition is met; if it is less, the predetermined second preset negative pressure threshold condition is not met.

[0116] In this embodiment, the air duct is first set to a closed state to quickly increase the negative pressure in the dust collection chamber. If the pressure difference in the dust collection chamber cannot meet the second preset negative pressure threshold condition after the fan is controlled to operate for a first preset time according to the reference average operating power, this embodiment continues to control the fan to operate for a first preset time according to the reference average operating power until the pressure difference in the dust collection chamber meets the second preset negative pressure threshold condition, that is, until the dust collection base station meets the preset operating conditions.

[0117] In some embodiments, controlling the fan to operate in the second suction mode includes the following steps: controlling the air duct of the dust collection base station to enter the open state, wherein when the air duct enters the open state, garbage can enter the dust collection chamber of the dust collection base station through the air duct, and controlling the fan to operate for a second preset duration according to the preset rated power.

[0118] In some embodiments, after controlling the fan to operate for a second preset duration, the control method of the dust collection base station further includes: calculating the total number of times the fan enters the second suction mode; if the total number is less than or equal to a preset number threshold, controlling the air duct of the dust collection base station to enter a closed state, and controlling the fan to operate for a first preset duration according to a preset reference average operating power.

[0119] After each second preset time of operation in the second suction mode, this embodiment determines whether the total number of times the fan has entered the second suction mode is less than or equal to a preset number threshold. If it is less than or equal to the threshold, this embodiment controls the air duct of the dust collection base station to enter the closed state, controls the fan to operate for a first preset time according to the preset reference average operating power, and after operating for the first preset time, controls the air duct of the dust collection base station to enter the open state, controls the fan to operate for a second preset time according to the preset rated power, and so on.

[0120] When the total number of times the fan enters the second suction mode is less than or equal to a preset threshold, the fan switches back and forth between the first suction mode and the second suction mode. The first suction mode has lower power consumption, while the second suction mode has higher waste collection efficiency. Therefore, this embodiment can control the fan with lower power consumption and higher waste collection efficiency.

[0121] It should be noted that in the above embodiments, there is no necessarily a certain order between the steps. Those skilled in the art can understand from the description of the embodiments of the present invention that the above steps may have different execution orders in different embodiments, that is, they may be executed in parallel or in turn, etc.

[0122] As another aspect of the embodiments of the present invention, the present invention provides a control device for a dust collection base station. The control device for the dust collection base station can be a software module, which includes several instructions stored in a memory. A processor can access the memory, call the instructions, and execute them to complete the control method for the dust collection base station described in the above embodiments.

[0123] In some embodiments, the control device of the dust collection base station can also be built from hardware devices. For example, the control device of the dust collection base station can be built from one or more chips, and the chips can work together to complete the control method of the dust collection base station described in the above embodiments. As another example, the control device of the dust collection base station can also be built from various logic devices, such as general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), microcontrollers, ARM (ArcRI SC Machinie) or other programmable logic devices, discrete gate or transistor logic, discrete hardware components, or any combination of these components.

[0124] Please see Figure 7 The control device 700 for the dust collection base station includes a dust collection preparation module 71 and a suction control module 72. The dust collection preparation module 71 is used to detect whether the dust collection base station meets the dust collection conditions when it is connected to the cleaning equipment. The suction control module 72 is used to control the fan to work in the first suction mode if the dust collection base station meets the preset operating conditions, and then control the fan to work in the second suction mode. The average suction power of the fan in the second suction mode is greater than that in the first suction mode, and the average operating power of the fan in the second suction mode is greater than that in the first suction mode.

[0125] When dust collection begins, this embodiment uses a low-power first suction mode to control the fan. This reduces the high noise generated when the fan starts working and avoids damage to the fan's circuit components caused by a large instantaneous drive current during startup, thus extending the fan's lifespan. When the dust collection station meets the preset operating conditions, this embodiment then uses a high-power second suction mode to control the fan. This improves waste collection efficiency. Therefore, this embodiment achieves a balance between low noise and efficiency, ensuring both reduced fan noise and extended fan lifespan while maintaining high waste collection efficiency at the dust collection station.

[0126] In some embodiments, the fan operates for less than or equal to 2 seconds in the first suction mode and for more than or equal to 10 seconds in the second suction mode.

[0130] In some embodiments, the maximum suction power of the fan in the first suction mode is equal to the average suction power of the fan in the second suction mode.

[0131] In some embodiments, the AC cycle of the fan operation includes a first half-cycle and a second half-cycle that are continuous in time and opposite in polarity. The dust collection preparation module 71 is further specifically used to: when the first zero-crossing point of the first half-cycle is detected, delay for a specified period of time, wherein the fan is in a power-off state during the specified period of time; after the specified period of time, control the fan to operate for 1 / 2 of the fan operating time until the second zero-crossing point of the first half-cycle is reached, at which point the fan is in a power-off state; when the third zero-crossing point of the second half-cycle is detected, delay for a specified period of time, wherein the fan is in a power-off state during the specified period of time; after the specified period of time, control the fan to operate for 1 / 2 of the fan operating time until the fourth zero-crossing point of the second half-cycle is reached, at which point the fan is in a power-off state.

[0132] In some embodiments, the dust collection preparation module 71 is further specifically used to: when the average operating power of the fan increases to the maximum average operating power, determine that the dust collection base station meets the preset operating conditions, and control the fan to operate in the second suction mode.

[0133] In some embodiments, the dust collection preparation module 71 is further specifically used to: determine the pressure difference of the dust collection base station, the pressure difference being the difference between the preset reference atmospheric pressure and the dust collection chamber air pressure of the dust collection base station; if the pressure difference meets the first preset negative pressure threshold condition, then determine that the dust collection base station meets the preset operating conditions, and control the fan to work in the second suction mode.

[0134] In some embodiments, the dust collection preparation module 71 is further specifically used to: control the air duct of the dust collection base station to enter a closed state, wherein when the air duct enters the closed state, garbage cannot enter the dust collection chamber of the dust collection base station through the air duct, and control the fan to work for a first preset time according to a preset reference average working power, wherein the reference average working power is less than the average working power of the second suction mode.

[0135] In some embodiments, the dust collection preparation module 71 is further specifically used to: control the air duct of the dust collection base station to enter the open state, wherein when the air duct enters the open state, garbage can enter the dust collection chamber of the dust collection base station through the air duct, and control the fan to work for a second preset time according to the preset rated power.
