Description

Technical Field

[0001] This invention relates to the field of smoke machine control technology, and in particular to a smoke machine control method and a smoke machine control system. Background Technology

[0002] As a new type of intelligent voice interaction device, the voice box has been gradually promoted in the kitchen field in recent years. Especially when used in conjunction with the range hood, its contactless operation brings great convenience and a sense of technology to users.

[0003] However, the application of the voice recognition box in the range hood environment still faces many challenges. The high-decibel noise generated by the range hood during operation typically ranges from 60 to 80 decibels, and can even exceed 85 decibels in high-power mode. This noise is characterized by a mixture of steady-state and dynamic noise, including low-frequency noise from the fan operation and high-frequency noise from the flow of cooking fumes, creating a complex acoustic environment. Against this high-noise background, the voice recognition system of the voice recognition box often struggles to accurately distinguish between the user's voice commands and environmental noise, resulting in a significant decrease in wake-up rate.

[0004] Therefore, improving the wake-up rate of the voice recognition box in a smoke hood environment has become an urgent technical challenge. It is necessary to improve the device's voice recognition capabilities in complex acoustic environments through hardware upgrades and algorithm optimization, thereby enhancing the user experience.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] To facilitate understanding of this embodiment, the application scenarios and design concepts of this application embodiment will be briefly introduced below.

[0027] As a common kitchen appliance, the noise level of a range hood affects the user experience. While a voice-activated smart box enhances the user's sense of technology, its operation is easily affected by the noise of the range hood, leading to a decrease in its wake-up rate. Therefore, there is an urgent need for a method to improve the voice wake-up rate.

[0028] Based on this, this application provides a range hood control method and a range hood control system to improve the voice wake-up rate based on the current location information of the cook and the temperature information of the voice interaction device.

[0029] Example 1 This application provides a method for controlling a range hood. The method is applied to a control unit in a range hood control system. The range hood control system further includes a voice interaction device 1 and a drive component for driving the voice interaction device 1 to move. The drive component is used to drive the voice interaction device 1 to move along a lateral path. The control unit is connected to the drive component and the voice interaction device 1.

[0030] Combination Figure 1 As shown, the method includes: S110, Obtain the current location information of the cooking personnel.

[0031] S120, based on the current location information, determine the first target displacement of the voice interaction device.

[0032] S130, the control drive component operates in a first mode to drive the voice interaction device to move a first target displacement along a lateral path toward the direction of the heat source.

[0033] S140, Obtain the current temperature information of the voice interaction device.

[0034] S150, based on the comparison between the current temperature information and the preset temperature threshold, calculate the second target movement position of the voice interaction device.

[0035] S160, the control drive component operates in a second mode to drive the voice interaction device to move a second target displacement along a lateral path in a direction away from the heat source.

[0036] The method provided in this application first adjusts the position of the voice interaction device 1 based on the real-time position of the cook, and then performs secondary optimization adjustment based on the temperature status of the voice interaction device 1 itself. Through two stages of intelligent movement adjustment, the voice interaction device 1 is always in the most ideal operating environment, which effectively reduces the negative impact of range hood noise and high-temperature fumes on voice recognition performance, significantly improves the wake-up success rate, and extends the service life of the device, bringing users a more intelligent and efficient user experience.

[0037] Step S110 uses sensors (such as infrared sensors, cameras, or ultrasonic positioning modules) to detect the position of the cook in the kitchen. This position information provides the basic data for the subsequent dynamic adjustment of the voice interaction device 1, ensuring that the device can optimize positioning based on the user's actual distance and orientation to reduce noise interference and improve the accuracy of voice signal acquisition. In this embodiment, an infrared sensor is used to collect the cook's position information, and the cook's position corresponds to the heat source of the cooking area.

[0038] In conjunction with the first aspect, step S120 includes: Calculate the first target displacement using the following formula:

[0039] in, For the first target displacement, This refers to the maximum physical displacement range that the voice interaction device 1 can move. The range of space that cooks can move around in, as defined by the standard for range hoods. For cooks relative to The distance from the starting point.

[0040] It can be understood that spatial proportion modeling is performed before step S110 of the present application, and two key spatial parameters are introduced , ; among them, is the maximum physical displacement range that the voice interaction device 1 can move, is the activity space range of cooking personnel defined by the standard of the range hood, is the distance of the cooking personnel relative to the starting point.

[0041] In step S120, according to the position information of the cooking personnel, an optimal first target displacement is calculated. Subsequently, in step S130, through a driving component (such as a motor, a slide rail, etc.), the voice interaction device 1 is moved in the direction close to the heat source according to the calculated first target displacement, so as to shorten the distance between the sound source and the microphone, reduce environmental noise interference, thereby improving the signal-to-noise ratio of voice signal acquisition and enhancing the wake-up sensitivity. This automatic adjustment mechanism can dynamically adapt to the user's operating environment, making it always in an optimal voice recognition position, further improving the user experience.

[0042] It can be understood that when the voice interaction device 1 works in a high-temperature oil fume environment, it is likely to affect the stability of its internal electronic components and even cause failures. Therefore, in step S140, the built-in temperature sensor is used to continuously monitor the current temperature information of the device.

[0043] Subsequently, in step S150, the measured current temperature is compared with a preset safe temperature threshold. If the current temperature is close to or exceeds this temperature threshold, a second target displacement is calculated.

[0044] Subsequently, in step S160, the movement instruction of the second step is executed again through the driving component, and the voice interaction device 1 is moved in the direction away from the heat source to move away from the high-temperature area and enter a more suitable working environment; if the current temperature is within the safe range, the existing position is maintained. This not only helps to reduce the performance degradation caused by high temperature, but also further avoids the influence of the range hood noise and improves the wake-up efficiency.

[0045] Combined with the first aspect, S150 includes: S151, if T≥T0, calculate the second target displacement according to the following formula:

[0046] where, is the second target displacement, is the gain, is the current temperature information, is the temperature threshold.

[0047] S152, if T<T0, determine that the second target displacement is 0.

[0048] It is understandable that step S150, as a key step for temperature regulation and displacement adjustment of the voice interaction device 1, its core purpose is to ensure that the voice interaction device 1 can operate stably at an appropriate ambient temperature, thereby improving device reliability and voice wake-up rate.

[0049] If T≥T0, it means that the ambient temperature where the voice interaction device 1 is currently located has reached or exceeded the safety range threshold, which may affect the normal operation of internal electronic components or cause performance degradation. At this time, enter the second target displacement calculation process to drive the voice interaction device 1 to move away from the cooking person to find a more suitable working position; if T<T0, it means that the current ambient temperature is within the safety range and will not affect the normal operation of the voice interaction device 1. Therefore, no additional position adjustment is required, and the second target displacement is determined to be "0", that is, the voice interaction device 1 remains in its current position unchanged.

[0050] In this way, by introducing temperature control logic, the voice interaction device 1 can not only dynamically respond to changes in the user's physical position, but also intelligently adapt to environmental temperature changes, avoid stability problems caused by overheating of the device, and the temperature threshold can be flexibly configured according to different scenarios, enhancing the adaptability and practicality of the system.

[0051] Among them, the gain is the preset initial value and can be adjusted according to actual needs. When the value of the current temperature information is relatively large, the temperature deviation is large. At this time, the calculated second target displacement is also large to achieve significant temperature reduction through one displacement; similarly, when the value of the current temperature information is relatively small, the temperature deviation is small, and the moving distance is also reduced, which can avoid overshoot. Compared with the method of moving a fixed step size, it can be controlled to be stable within 2 - 3 adjustments.

[0052] Combined with the first aspect, after step S160, it further includes: S170, obtaining the updated temperature information when the voice interaction device moves a specified distance along the direction away from the heat source.

[0053] S180, calculating the temperature change amount based on the updated temperature information and the current temperature information.

[0054] S190, calculating the quotient of the specified distance and the temperature change amount to update the gain.

[0055] Specifically, calculate with the following formula

[0056] in, For the updated gain, The specified distance that the voice interaction device 1 moves away from the heat source; The voice interaction device 1 is moved away from the heat source. The subsequent temperature change. Thus, the gain is adjusted according to the actual situation, so that the position of the voice interaction device 1 can be adjusted more accurately next time.

[0057] As one feasible approach, the drive assembly includes a slide rail, a motor, and a drive component. The motor's output is connected to a transmission component, which in turn is connected to a voice interaction device 1. The control unit controls the motor to output power, which is then transmitted to the voice interaction device 1 via the transmission component. This allows the voice interaction device 1 to slide along the slide rail, moving closer to or further away from the cooking area where the heat source is located. Understandably, while this method achieves position adjustment, the presence of the motor and transmission component significantly increases the internal space occupied by the range hood. This is especially problematic in kitchen appliances with limited space, where the fan assembly is already integrated. The layout becomes difficult, and the connections between multiple components require additional support structures and installation locations, increasing the overall complexity and manufacturing cost of the appliance.

[0058] As another feasible approach, charged conductors (such as an electromagnet array) are placed on both sides of the lateral displacement path of the voice interaction device 1. By adjusting the current on both sides, the magnetic force is changed, enabling the voice interaction device 1 to move freely laterally. This method results in a simple structure, eliminates traditional moving parts (such as slide rails and motors), saves space, offers high reliability, and facilitates multi-degree-of-freedom control. In this embodiment, the drive assembly using this structure drives the lateral movement of the voice interaction device 1, simplifying the overall structure of the smoke machine compared to traditional motor-driven and transmission-based methods.

[0059] In conjunction with the first aspect, the driving component includes a first energized conductor 2 and a second energized conductor 3 disposed at the top of the smoke collection chamber of the smoke machine. The first energized conductor 2 and the second energized conductor 3 are respectively disposed on both sides of the voice interaction device 1. The first energized conductor 2 and / or the second energized conductor 3 are energized to drive the voice interaction device 1 to move along the lateral movement path between the energized first energized conductor 2 and the second energized conductor 3.

[0060] Understandably, for a charged conductor, the relationship between the magnetic force F and the distance d approximately follows the relationship between F and 1 / d. 2 Proportional to each other, when the magnetic forces generated by the charged conductors on both sides (i.e., the first charged conductor 2 and the second charged conductor 3) are equal, the voice interaction device 1 is in lateral equilibrium and is in a static state; once the position of the voice interaction device 1 on the lateral path is known, the distance d of that position relative to the starting point on one side can be determined. 左 The distance d relative to the other side's focal point 右Therefore, it is possible to calculate the magnetic force F on both sides. 左 F 右 Since the magnetic force F is proportional to the current, the magnitude of the magnetic force on the charged conductors on both sides can be adjusted by adjusting the current, thereby driving the voice interaction device 1 to move laterally.

[0061] Step S130, controlling the operation of the drive component to drive the movement of the voice interaction device, specifically includes: S131, based on the first target displacement, calculate the first operating current of the first charged conductor and / or the second operating current of the second charged conductor.

[0062] After calculating the first target displacement in step S130, and combining the initial position of the voice interaction device 1 and the area where the cook is located, the distance of the voice interaction device 1 relative to the first charged conductor 2 and the second charged conductor 3 after the first target displacement is moved laterally can be calculated, and the current values ​​(i.e. the first working current and the second working current) that need to be applied to the first charged conductor 2 and / or the second charged conductor 3 can be deduced.

[0063] Understandably, the magnitude of the current value determines the magnetic field strength, which in turn determines the magnitude of the driving force on the voice interaction device 1. If it needs to move to the left, the voice interaction device 1 is driven to move by one or more methods, such as increasing the current in the charged conductor on the left and decreasing the current in the conductor on the right; and vice versa.

[0064] S132, a first operating current is applied to the first charged conductor, and a second operating current is applied to the second charged conductor, so as to drive the voice interaction device to move the first target displacement through the magnetic field generated by the first charged conductor and the second charged conductor.

[0065] The control unit outputs the calculated first operating current to the first charged conductor 2 and the second operating current to the second charged conductor 3. The current generates a magnetic field after passing through the conductors, which interacts with the magnet inside or outside the voice interaction device 1. Preferably, during the movement of the voice interaction device 1, the system continuously monitors its actual displacement. If the actual displacement deviates from the target offset distance, the control unit dynamically adjusts the current value to achieve closed-loop control.

[0066] Similarly, the process of moving the second target displacement in step S160 is similar to the above process and will not be described in detail here.

[0067] Understandably, in this embodiment, the voice interaction device 1 is driven to move freely in the lateral direction by magnetic force adjustment, but dynamic friction still exists during the movement, resulting in energy loss. In order to reduce the impact of energy loss on displacement accuracy during the movement, in this embodiment, a third charged conductor 4 is set on the lateral path. The magnetic force provided to the third charged conductor 4 is equal to the weight of the voice interaction device 1, and it is mutually repelled by the magnet set at the bottom of the voice interaction device 1. This allows the voice interaction device 1 to be completely suspended above the lateral path. In this way, when the voice interaction device 1 moves laterally driven by the change of magnetic force on both sides, energy loss is reduced, which helps to improve displacement accuracy and control stability.

[0068] Furthermore, a fence is provided outside the first charged conductor 2 and the second charged conductor 3 to limit the movement range of the voice interaction device 1 in a target direction. This target direction is on the same horizontal plane as the lateral direction and perpendicular to it. Preferably, a fourth charged conductor and a fifth charged conductor are also provided outside the fence, with their magnetic properties opposite to those of the magnets inside the voice interaction device 1. The voice interaction device 1 moves along the lateral direction... Figure 2 The left and right directions are limited by the fourth and fifth charged conductors, which restrict the range of movement of the voice interaction device 1 in the front and back directions.

[0069] In conjunction with the first aspect, after step S160, the following also includes: S161, Obtain the first temperature information of the voice interaction device.

[0070] S162, if the first temperature information is less than the temperature threshold, calculate the first offset distance based on the first temperature information.

[0071] S163, control the drive component to operate in a first mode to drive the voice interaction device to move a first offset distance along a lateral path toward the direction of the heat source.

[0072] S164, determine whether the second temperature information of the voice interaction device has reached the temperature threshold.

[0073] If not, proceed to step S165.

[0074] S165, Determine the current location as the target location of the voice interaction device.

[0075] Understandably, steps S110-S160 involve two position adjustments to the voice interaction device 1. To prevent excessive adjustment in step S160, one or more adjustments can be made using a temperature feedback mechanism until the optimal position is reached. If so, it indicates that the current position is within the safe operating range of the device, and the voice interaction device 1 has not been moved too close to a heat source due to excessive adjustment, resulting in a temperature increase. In this case, the current operating mode can be maintained.

[0076] Specifically, after the first position adjustment of the voice interaction device 1, if the current temperature reaches a temperature threshold, the device is moved laterally away from the heat source to complete a second position adjustment. Then, the first temperature information after the second position adjustment is acquired. Since the device is now further away from the heat source, the temperature will inevitably decrease. However, to avoid excessive adjustment in the second position, the offset distance is calculated based on this first temperature information to perform a third position adjustment of the voice interaction device 1 towards the heat source. If the second temperature information after the third position adjustment is less than the temperature threshold, it indicates that the position is within the safe operating range of the device and is closer to the heat source than the position after the second adjustment; therefore, this position is confirmed as the target position for the voice interaction device 1. However, if the second temperature information after the third position adjustment reaches the temperature threshold, it indicates that the voice interaction device 1 has failed to effectively avoid the heat source. In this case, the device is adjusted further away from the heat source… until the temperature after a certain adjustment is less than the temperature threshold, thus confirming the target position.

[0077] In conjunction with the first aspect, such as Figure 3 As shown, the method also includes: S210, in response to a user gesture command, determines whether the user gesture command is the first specified command.

[0078] If so, proceed with steps S220-S250.

[0079] S220, the control drive component operates in a first mode to drive the voice interaction device to move a first distance along a lateral path toward the heat source.

[0080] S230, acquire the third temperature information of the voice interaction device.

[0081] S240, if the third temperature information reaches the temperature threshold, calculate the offset distance based on the third temperature information.

[0082] S250, the control drive component operates in a second mode to drive the voice interaction device to move a distance away from the heat source along a lateral path and to provide feedback with specified voice information.

[0083] In this embodiment, step S210 collects raw gesture data through a camera, infrared sensor or gesture recognition module, and determines whether it is a "first designated instruction" (specifically, a "beckoning" gesture) by using a preset gesture recognition algorithm (such as CNN, LSTM or preset gesture template matching). If it is a designated gesture, subsequent actions are triggered, and steps S220-S250 are executed.

[0084] Upon receiving the "first designated instruction", the voice interaction device 1 is brought closer to the heat source by the driving component to form an interaction and enhance the user experience.

[0085] Subsequently, temperature monitoring is performed. When the third temperature information reaches the temperature threshold, the voice interaction device 1 is driven away from the heat source to prevent the device from overheating due to proximity to the heat source, which could affect performance or safety.

[0086] In conjunction with the first aspect, after step S210, the following is also included: If not, proceed to steps S260-S270.

[0087] S260, confirm the gesture command as the second designated command.

[0088] S270, the control drive component operates in a second mode to drive the voice interaction device to move along a lateral path away from the heat source.

[0089] In this embodiment, the "second instruction" is a gesture to back away. At this time, the voice interaction device 1 is driven to avoid disturbing the user or to maintain distance when the user has no need, thereby reducing energy consumption.

[0090] Understandably, third to Nth gestures and corresponding control flows can also be set to achieve different control functions. This will not be elaborated upon here.

[0091] Secondly, this application also provides a range hood control system, including a control unit, a voice interaction device 1, and a drive component for driving the voice interaction device 1 to move, the drive component being used to drive the voice interaction device 1 to move along a lateral path; the control unit is connected to the drive component and the voice interaction device 1; the control unit is used to execute the above-described range hood control method.

[0092] In conjunction with the second aspect, the driving component includes: a first energized conductor 2 and a second energized conductor 3 disposed at the top of the smoke collection chamber of the smoke machine, the first energized conductor 2 and the second energized conductor 3 respectively disposed on both sides of the voice interaction device 1, the first energized conductor 2 and / or the second energized conductor 3 being energized to drive the voice interaction device 1 to move along the lateral movement path between the energized first energized conductor 2 and the second energized conductor 3.

[0093] Thirdly, embodiments of this application provide an electronic device, combined with Figure 4 As shown, the electronic device includes a memory 131 and a processor 130. The memory 131 stores a computer program, and the processor 130 runs the computer program to make the electronic device perform the above-described method.

[0094] Furthermore, combined Figure 4 The electronic device shown also includes a bus 132 and a communication interface 133, with the processor 130, the communication interface 133 and the memory 131 connected via the bus 132.
