Description

Technical Field

[0001] This invention relates to the field of cleaning robot technology, and more particularly to a cleaning device control system. Background Technology

[0002] Dust mites are microscopic pests invisible to the naked eye, yet they are potent allergens; their corpses, secretions, and excrement are all allergens. Nearly one-third of China's population suffers from allergies; according to epidemiological surveys in China, dust mites are the allergen in up to 70% of these allergic disease patients. The proportion is even higher among children. Allergic diseases caused by dust mites mainly include allergic rhinitis, allergic conjunctivitis, allergic asthma, and allergic dermatitis, which can affect patients' daily work and life, and in severe cases, even endanger their lives. Dust mite removers are common household appliances that primarily rely on ultraviolet (UV) lamps to kill mites and germs.

[0003] Existing mite removal devices all use fixed working modes and times for dust or mite removal. They cannot intelligently adjust the working mode and time according to the actual situation of dust or mites, so their intelligence level is relatively low and their dust and mite removal is relatively poor.

[0060] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0061] To enable those skilled in the art to better understand the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0062] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0063] See Figure 1 This invention provides a cleaning device control system, including: a controller, a roller brush motor control circuit, an adsorption motor drive circuit, and a dust sensing circuit. The roller brush motor control circuit is used to drive and control the roller brush device; the adsorption motor drive circuit is connected to the controller to drive and control the adsorption device under the control of the controller. Figure 1 As shown, the controller acts as the control center, uniformly managing and controlling all peripherals and performance of the cleaning device. During dust / mite removal, the controller drives the adsorption motor circuit to drive the adsorption device to adsorb dust or mites into the cleaning device. In some embodiments, the controller also drives the roller brush to rotate by controlling the roller brush motor control circuit. During operation, the roller brush contacts the object being cleaned, thereby collecting or tapping dust or mites on the surface of the object, thus better adsorbing dust or mites into the cleaning device.

[0064] The dust sensing circuit is connected to the controller, which includes a dust detection module. The dust detection module is used to collect dust data through the dust sensing circuit and automatically adjust the working mode and time based on the collected dust data.

[0065] Specifically, due to varying environments, the amount of dust or mites on the surface of objects differs. If a cleaning device operates according to a uniform mode and time, the cleaning effect may not be satisfactory. Therefore, the dust sensing circuit collects data on the dust and / or mites on the surface of the object being cleaned and outputs the data to the controller. The controller can then adjust the cleaning device's operating mode and time based on the amount of dust and / or mites. In some embodiments, multiple operating modes may include tapping, sweeping, vacuuming, sterilization, and drying to meet the cleaning needs of different users. This automatic adjustment of the cleaning device's operating mode and time based on different dust or mite data improves cleaning effectiveness and efficiency.

[0066] See Figure 5 The controller may include a microcontroller U5, which controls each functional module through its external pins.

[0067] See Figure 6 The roller brush motor control circuit includes a full-bridge rectifier BD2, a filter inductor LF2, a filter capacitor EC7, a fuse F2, and capacitors CY3 and CY4, etc., to convert the input AC mains power into DC power and drive the DC roller brush to rotate.

[0068] See Figure 7 The adsorption motor drive circuit includes a transistor Q3 and a relay K2. Transistor Q3 is turned on or off under the control of the controller's output signal MOTOR_EN. When the controller outputs a high-level signal, transistor Q3 turns on, causing relay K2 to also turn on, thus connecting the power supply to the adsorption device and initiating dust adsorption. Conversely, when the controller outputs a low-level signal, transistor Q3 turns off, relay K2 turns off, and the adsorption device stops adsorbing dust.

[0069] See Figure 2The dust detection module includes: a dust baseline value acquisition module, a latest dust data acquisition module, a dust validity judgment module, and a dust baseline value adjustment module. The dust baseline value acquisition module is used to acquire the dust data baseline value; the latest dust data acquisition module is used to acquire the latest dust data within a set time interval; the dust validity judgment module is used to judge whether the acquired latest dust data is valid; and the dust baseline value adjustment module is used to judge whether the dust baseline value needs to be adjusted based on the current valid dust data.

[0070] Specifically, such as Figure 2 As shown, before the cleaning instrument starts working, the microcontroller controller needs to obtain the baseline of the current environmental dust AD value. The dust baseline value acquisition module obtains the average dust AD values ​​V1, V2, and V3 within three 500us intervals, and takes the maximum value as the baseline value. During the dust removal process, the microcontroller controller obtains the latest dust data within a set time interval through the latest dust data acquisition module. A translation update method is used to store the latest dust AD value data within the last 500us interval into an array. During this process, the microcontroller controller uses the dust validity judgment module to determine whether the latest dust data is valid. The dust validity judgment module includes a baseline value comparison module, which determines whether the latest dust data is lower than the baseline (the baseline value needs to include interference values ​​from voltage fluctuations). If so, the dust is considered valid. Finally, the microcontroller controller uses the dust baseline value adjustment module to determine whether the dust baseline value needs adjustment based on the current valid dust data. When a corresponding change in the current dust amount data is detected, the dust amount at the current dust removal point has changed accordingly. This is to achieve a better dust removal effect. The dust baseline value needs to be adjusted.

[0071] Furthermore, in one embodiment of the present invention, the dust baseline value adjustment module includes: a baseline value adjustment module, a real-time baseline value adjustment module, and a blockage fault alarm module. The baseline value adjustment module is used to adjust the dust baseline value according to the amount of change in the dust detection module or ambient light when the dust detection device or ambient light changes. Since changes in the dust detection module or ambient light have a relatively significant impact on the dust baseline value, it is necessary to adjust the baseline value accordingly for better dust removal. During machine operation, the baseline value needs to be adjusted in real time due to dust accumulation in the infrared tube or changes in ambient light.

[0072] The baseline real-time adjustment module is used to adjust the dust baseline value in real time when it detects that the latest dust data is higher or lower than the baseline for an extended period; thus, the amount of dust at the current dust removal point changes accordingly. To achieve better dust removal results, the dust baseline value needs to be adjusted.

[0073] The blockage fault alarm module is used to issue an alarm when it detects that the infrared tube is blocked by a foreign object. If an object is detected blocking the infrared tube, an error will be reported to facilitate troubleshooting and ensure the normal operation of the machine.

[0074] See Figure 2 The dust detection module further includes a dust quantity calculation module and a first control decision module. The dust quantity calculation module is used to process the difference between all the latest valid dust data and the baseline within a certain time to obtain the current dust quantity; and to process the difference between all valid dust values ​​and the baseline value within a certain time, such as within 10ms, to determine the current dust throughput.

[0075] The first control decision module determines the dust removal working mode and time based on the current dust level and control strategy. This control system uses sensors to acquire and identify the number of mites and dust on the bed sheet surface, automatically adjusting the working time and intensity of the mite remover based on the identification results, achieving intelligent cleaning. Multiple working modes include tapping, sweeping, vacuuming, sterilization, and drying, meeting the cleaning needs of different users and improving cleaning effectiveness and efficiency.

[0076] See Figure 3The dust detection module further includes a mite and dust quantity detection module, which comprises: a data preprocessing module, a feature extraction module, a model training module, a mite and dust quantity prediction module, and a second control decision module. The data preprocessing module preprocesses the collected sensor data; the feature extraction module extracts features related to the mite and dust quantity from the preprocessed data; the model training module trains the extracted features using machine learning algorithms to establish a prediction model for the mite and dust quantity; the mite and dust quantity prediction module predicts the quantity of new sensor data based on the trained model; and the second control decision module sets the working mode and time for mite removal and dust removal based on the estimated mite and dust quantity and a control strategy. Specifically, in one embodiment of the invention, the mite and dust quantity can also be detected using artificial intelligence. After the controller collects mite and dust quantity data from the surface of the bed sheet through sensors, the data preprocessing module preprocesses the collected sensor data. The collected sensor data undergoes preprocessing, including filtering, outlier removal, and normalization. Then, a feature extraction module and a model training module generate a prediction model for the number of mites and dust particles. This prediction model can predict the number of mites and dust particles from new sensor data, yielding estimated values. Simply relying on sensor-collected AD data to determine the number of mites and dust particles results in relatively large errors and computational burdens. In this embodiment, a trained prediction model is used to predict the number of mites and dust particles, ultimately providing relatively accurate estimates. Furthermore, once the training model is established, the controller only needs to compare the collected data with the training model to obtain the estimated number of mites and dust particles, reducing the controller's computational load. For example, when counting particles using a particle counter, counting too many particles significantly increases the computational burden.

[0077] See Figure 8The dust sensing circuit includes an infrared emitting circuit and an infrared receiving circuit. The infrared emitting circuit includes a transistor Q4 and an infrared emitting tube. The base of the transistor Q4 is connected to the infrared emitting control terminal of the controller through a resistor R39. The emitter of the transistor Q4 is connected to a reference ground. The collector of the transistor Q4 is connected to the negative terminal of the infrared emitting tube. The positive terminal of the infrared emitting tube is connected to a pull-up power supply through a resistor R55. The infrared receiving circuit includes an infrared receiving tube. The positive terminal of the infrared receiving tube is connected to a pull-up power supply through a resistor R36. The negative terminal of the infrared receiving tube is connected to a reference ground through a resistor R40. The negative terminal of the infrared receiving tube is also connected to the infrared data acquisition terminal of the controller through a resistor R28.

[0078] Specifically, in dust detection, air containing particles is drawn in from the sampling port and passed through a light-sensitive area. For example... Figure 8 As shown, the controller controls the transistor Q4 to conduct via the Dust_TX signal terminal, causing infrared emission. Dust particles, when illuminated, scatter light signals proportional to the particle's intensity. These signals are received by the infrared receiver photosensitive device and output to the controller via the Dust_RX signal terminal. The controller can then directly acquire dust data via the AD data acquisition terminal. In existing technologies, dust sensing signals are typically read using operational amplifier ICs (such as LM358, LM324, etc.), which increases component and PCB space costs. In this embodiment, instead of using an operational amplifier IC to amplify the dust sensing signal, the weak infrared sensing signal is directly input to the controller's I / O port. Infrared dust sensing acquisition is achieved through software algorithms and the controller's MCU internal circuit logic, resulting in lower costs and a smaller acquisition device footprint.

[0079] See Figure 1 , Figure 9 , Figure 10 and Figure 11 The cleaning device control system further includes: a heating control circuit, a temperature detection circuit, a UV lamp control circuit, and a lift angle and distance sensing circuit. The heating control circuit is connected to the controller to drive and control the heating device under the control of the controller. Figure 9 As shown, the heating control circuit is connected to the controller via the Heat_EN signal terminal. The controller output signal is amplified by transistor Q2 and then used to control the switching of the thyristor T1 via optocoupler U2. When the thyristor T1 is turned on, the AC power supply can supply power to the heating wire, and the heating wire starts to heat. Conversely, when the thyristor T1 is turned off, the heating wire stops heating.

[0080] The temperature detection circuit is connected to the controller to transmit the collected temperature signal to the controller, which also controls the switching of the heating device based on the temperature signal; for example Figure 9 As shown, the temperature detection circuit transmits the collected temperature signal to the controller via TEMP_AD. In this way, the controller can obtain the heating temperature and stop heating the heating wire when the heating temperature exceeds the set value.

[0081] The ultraviolet lamp control circuit is connected to the controller to drive and control the ultraviolet lamp under the control of the controller; such as Figure 10 As shown, the controller controls the switching of the ultraviolet lamp control circuit via the UV_EN signal terminal. When the UV_EN signal is high, transistor Q8 conducts, causing MOSFET Q7 to conduct, and power supply 12 supplies power to the ultraviolet lamp, turning it on. Conversely, when the UV_EN signal is low, the ultraviolet lamp is off.

[0082] The lifting angle distance sensing circuit is connected to the controller to obtain the distance and tilt angle between the ultraviolet lamp and the object being cleaned. Figure 11 The lift-off angle distance sensing circuit includes: a first infrared emitting circuit, a first infrared receiving circuit, a second infrared emitting circuit, and a second infrared receiving circuit. The first infrared emitting circuit includes a transistor Q5 and a first infrared emitting diode. The base of the transistor Q5 is connected to the first infrared emitting control terminal of the controller through a resistor R47. The emitter of the transistor Q5 is connected to the positive terminal of the first infrared emitting diode through a resistor R53. The collector of the transistor Q5 is connected to a pull-up power supply. The first infrared receiving circuit includes a first infrared receiving diode. The positive terminal of the first infrared receiving diode is connected to one end of a resistor R46. The other end of the resistor R46 is connected to the other end of a resistor R37. The other end of the resistor R37 is connected to a pull-up power supply. 46. ​​The common terminal of resistor R37 is connected to the first distance detection terminal of the controller; the second infrared emitting circuit includes transistor Q6 and a second infrared emitting tube. The base of transistor Q6 is connected to the second infrared emitting control terminal of the controller through resistor R49. The emitter of transistor Q6 is connected to the positive terminal of the second infrared emitting tube through resistor R54. The collector of transistor Q6 is connected to a pull-up power supply; the second infrared receiving circuit includes a second infrared receiving tube. The positive terminal of the second infrared receiving tube is connected to one end of resistor R48. The other end of resistor R48 is connected to the other end of resistor R38. The other end of resistor R38 is connected to a pull-up power supply. The common terminal of resistors R48 and R38 is connected to the second distance detection terminal of the controller.

[0083] Specifically, by employing two infrared transceiver circuits, the lifting distance and angle of the cleaning device can be detected. When the cleaning device is lifted or tilted, it may be necessary to turn off the ultraviolet lamp. In existing technologies, UV lift detection is mainly achieved by measuring the vertical distance between the cleaning device and the contact surface. In this embodiment, two infrared transceiver circuits are used for inspection, thus adding the detection of the cleaning device's lift angle to the vertical distance detection. Taking one type of detection as an example, the controller controls the switching of one infrared emitting circuit through the UV_Left_TX signal terminal. When the UV_Left_TX signal is high, transistor Q5 is turned on, and the infrared receiving tube generates an infrared signal to detect the distance or angle. The signal from the infrared receiving tube is received through the UV_Left_RX signal terminal, thereby obtaining the vertical distance or angle between the cleaning device and the contact surface.

[0084] See Figure 12 The cleaning device control system further includes a zero-crossing detection circuit, which is connected to the controller and the input AC power. The zero-crossing detection circuit detects the zero-crossing voltage of the input AC power and transmits the zero-crossing voltage information to the controller. The controller also controls the switching of the roller brush motor control circuit, the adsorption motor drive circuit, and the heating control circuit based on the zero-crossing voltage information. In AC load circuits, high-power relays will generate arcs when interrupted under current. These arcs corrode the contacts, and over time, may cause the relay contacts to stick together, losing their control function and failing to cut off the circuit. If the circuit is cut off when the circuit current is small, the arcing can be effectively suppressed. In AC circuits, the current is minimum at the zero-crossing point, and cutting off the circuit at this time can effectively suppress the arc. Therefore, a zero-crossing detection circuit is needed. Zero-crossing detection not only effectively suppresses the arc but also prevents power devices from interfering with the arc during interruption. Specifically, as shown... Figure 12 As shown, when the AC-L terminal is positive and the AC-N terminal is negative, the optocoupler is on, and the AC_0_Signal signal terminal outputs a low level to the controller; conversely, when the AC-L terminal is negative and the AC-N terminal is positive, the optocoupler is off, and the AC_0_Signal signal terminal outputs a high level to the controller. The controller can obtain the zero-crossing signal by detecting the alternation of high and low voltages, and at the zero-crossing point, it controls the switching of the heating control circuit, the ultraviolet lamp control circuit, the adsorption motor drive circuit, and the roller brush motor control circuit.

[0085] The working process of the cleaning device control system is as follows: Figure 4As shown in the diagram, after powering on, the circuit board controls the green dust indicator, open the interface, activate PTC heating, and turn on the suction and roller brush motors, entering working mode. The machine checks if the temperature has reached the set value and detects if the machine has been lifted or if there are any abnormalities, taking appropriate action. During operation, the machine automatically adjusts parameters such as suction power, tapping intensity, and sterilization time based on the type of mites and the cleaning area, achieving personalized and intelligent cleaning.
