Description

Technical Field

[0001] The present invention relates to the technical field of toys, and in particular to a lighting control system, an intelligent toy and a use method thereof. Background Art

[0002] The existing smart plush toys on the market use a circuit module to drive the motor to drive the internal mechanical structure so that some parts of the toy can automatically perform certain actions and speak some simple voices and music. However, due to the mechanical drive structure, the movable function is increased, resulting in the following problems:

[0003] Plush products are more of an active toy product, which can interact with consumers through some actions and voices. Most of them are children's toys. They cannot meet the needs of adults and cannot provide some functions such as sleep protection that adults need. Single young people, in particular, need companionship. Summary of the invention

[0004] In view of this, the present invention provides a lighting control system, an intelligent toy and a method of using the same to solve the problem that existing intelligent plush toys cannot provide the sleep protection function required by adults.

[0005] In a first aspect, the present invention provides a lighting control system, comprising a brightness acquisition module, a voice acquisition module, a control chip and a lighting module, wherein the output ends of the brightness acquisition module and the voice acquisition module are respectively connected to the input end of the control chip, and the output end of the control chip is connected to the controlled end of the lighting module;

[0006] The brightness acquisition module acquires the brightness of the surrounding environment and feeds back the brightness signal to the control chip. The control chip compares the brightness signal value transmitted by the brightness acquisition module with the set brightness threshold to determine whether the surrounding environment has become darker;

[0007] When the brightness signal value transmitted by the brightness acquisition module is lower than the brightness threshold, the control chip determines that the surrounding environment is darkened, the voice acquisition module collects the sound in the surrounding environment and feeds the sound signal back to the control chip, and the control chip determines whether the sound in the surrounding environment is a uniform breathing sound;

[0008] When the control chip determines that the sound in the surrounding environment is a uniform breathing sound, the control chip controls the lighting module to reduce the lighting brightness.

[0009] The beneficial effects of the above-mentioned toy are:

[0010] Through the collaborative work of the brightness acquisition module and the voice acquisition module, the above-mentioned light control system can be applied to smart plush toys, so that the smart plush toys can automatically adjust the light brightness when the surrounding environment is detected to be dark and the uniform breathing sound is recognized. This function is particularly suitable for single young people, and can provide them with soft light companionship at night, which helps to alleviate loneliness, enhance a sense of security, and help sleep. Unlike traditional smart plush toys with mechanical structures, the present invention does not rely on motors and mechanical structures to achieve interactive functions, which not only reduces the complexity and potential failure points of the product, but also makes the product lighter, softer, and more suitable for adults.

[0011] The above-mentioned lighting control system, through the combination of brightness acquisition module and voice acquisition module, can intelligently perceive the changes in surrounding brightness and sound, and respond accordingly based on this information. For example, at night when the room becomes dark and the user's even breathing sound is detected, the light brightness is automatically reduced to prevent sudden strong light from disturbing the user's sleep. Because it is driven by sensors rather than mechanically, the overall system power consumption is low, which extends the product's battery life and improves the user experience.

[0012] The above-mentioned lighting control system can respond to user voice commands through the voice acquisition module, such as playing soothing music or stories, further enhancing the interactivity of the product.

[0013] In an optional embodiment, the control chip has a built-in digital signal processor, and the digital signal processor is used to preprocess the sound signal, extract time domain and frequency domain features, classify the features, and determine whether it is a uniform breathing sound.

[0014] The beneficial effects of the above technical solution are: compared with simple volume detection, the digital signal processor can effectively distinguish background noise and other non-breathing sounds through in-depth analysis of sound signals, thereby improving the accuracy of breathing sound recognition and reducing the possibility of misjudgment. When the digital signal processor confirms that the sound in the surrounding environment is a uniform breathing sound, the control chip will trigger the light module to reduce the brightness. This function is particularly useful at night. It can automatically dim the lights after the user falls asleep to avoid strong light interfering with sleep and provide a more comfortable sleeping environment.

[0015] In an optional implementation, the lighting control system further includes a sound module; when the control chip determines that the sound in the surrounding environment is a uniform breathing sound, the control chip controls the sound module to play sleep-aiding white noise.

[0016] The beneficial effect of the above technical solution is that the lighting control system realizes intelligent recognition and response to the sound of even breathing by integrating the sound module. When the control chip determines that the sound in the surrounding environment is even breathing, the system will automatically play white noise to help sleep, thereby creating a more comfortable and quiet sleeping environment and improving the overall experience of the user.

[0017] In an optional embodiment, the control chip has a built-in timer; when the control chip controls the light module to reduce the brightness of the light, and the control chip controls the sound module to play sleep-aiding white noise, the timer starts timing, and when the time set by the timer is reached, the control chip controls the light module to turn off the light, and the control chip controls the sound module to turn off the sleep-aiding white noise.

[0018] The beneficial effects of the above technical solution are: through the built-in timer, the control chip can maintain a low light brightness and sleep-aiding white noise for a period of time after the user falls asleep. When the preset time is reached, the light is automatically turned off and the white noise playback is stopped. This not only improves the intelligence level of the system, but also ensures that the user has a more comfortable and quiet sleeping environment at night, while avoiding long-term unnecessary energy consumption.

[0019] In a first aspect, the present invention provides an intelligent toy, comprising:

[0021] A light control system is provided inside the toy body.

[0022] In an optional embodiment, a posture sensor is provided on the toy body, and the posture sensor is used to convert the posture signal and acceleration signal of the toy body into electrical signals and feed them back to the control chip. The control chip analyzes the current signal characteristics, determines the current action, and plays the corresponding offline voice through the sound module.

[0023] The beneficial effects of the above technical solution are as follows: the attitude sensor includes a three-axis gyroscope and a three-axis accelerometer. The three-axis gyroscope is used to measure the rotation angle of the toy body in three axes and provide accurate attitude information. The three-axis accelerometer is used to measure the acceleration of the toy body in three axes to help identify the motion state of the toy (such as tilt, flip, shake, etc.).

[0024] In an optional embodiment, the toy body includes a toy head, a toy body, toy arms, toy legs and a head hat, the toy head has toy ears; the posture sensor is arranged inside the toy body; and the lighting control system is arranged on the toy head.

[0025] In an optional embodiment, a touch sensor or / carbon film button is provided on the toy body. When the touch sensor or / carbon film button is touched, the touch sensor or / carbon film button feeds back the touch information to the control chip, so that the control chip controls the sound module to play the corresponding offline voice;

[0026] And / or, the toy ear is provided with a tension sensor, and when the toy ear is pulled, the tension sensor feeds back tension information to the control chip, so that the control chip controls the sound module to play the corresponding offline voice;

[0030] In an optional implementation, the control chip is wirelessly connected to the mobile phone APP, and the control chip can transmit the temperature information detected by the temperature sensor to the mobile phone APP.

[0031] In a third aspect, the present invention provides a method for using an intelligent toy, comprising the following steps:

[0032] A variety of trigger conditions are set. When a certain trigger condition is reached, the interaction mode corresponding to the trigger condition is triggered, and the offline voice corresponding to the trigger condition is played.

[0033] The beneficial effects of the above technical solution are: by setting multiple trigger conditions, users can interact with toys in a natural way. Different trigger conditions correspond to specific interaction modes and voice content, and can be customized according to user preferences and needs to provide personalized companionship and services.

[0034] In an optional embodiment, the interaction mode includes a voice interaction mode; the set trigger condition is a set sound; when the voice acquisition module acquires the set sound, the voice acquisition module converts the sound signal into an electrical signal and transmits it to the control chip; if the connection to the cloud is successful, the control chip will send the sound information to the cloud for processing, and play the corresponding audio according to the returned result; if the connection to the cloud fails, the control chip will match the sound signal with the built-in offline wake-up word, and play the corresponding offline voice after the match is successful; if the match fails, the network connection disconnection prompt sound will be played.

[0035] The beneficial effects of the above technical solution are: when the connection to the cloud is successful, richer cloud resources can be used for complex processing, and the corresponding audio can be played according to the returned results; when the cloud cannot be connected, basic services can still be provided through the built-in offline wake-up word matching, ensuring the continuity and stability of the functions.

[0047] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0048] The existing smart plush toys on the market use a circuit module to drive the motor to drive the internal mechanical structure so that some parts of the toy can automatically perform certain actions and speak some simple voices and music. However, due to the mechanical drive structure, the movable function is increased, resulting in the following problems:

[0049] Plush products are more of an active toy product, which can interact with consumers through some actions and voices. Most of them are children's toys. They cannot meet the needs of adults and cannot provide some functions such as sleep protection that adults need. Single young people, in particular, need companionship.

[0050] Based on this, the present invention provides a lighting control system, which controls the lighting brightness to switch to a low brightness state based on the brightness and sound of the external environment, and controls the sound module to play sleep-aiding white noise, so as to meet the needs of protecting sleep.

[0051] In addition, current plush products cannot provide some functions that adults need, such as emotional comfort and emotional companionship. The intelligent dialogue of the product is relatively simple, and it is simple communication through language, and it is impossible to interact and generate language communication.

[0052] Based on this, the present invention provides an intelligent toy, which uses a voice collection module to collect the user's voice, and plays the corresponding offline voice through a control chip, thereby realizing interaction with the user.

[0053] Combine the following Figures 1 to 3 , elaborate on the lighting control system of the first aspect of the present invention and the intelligent toy of the second aspect of the present invention.

[0054] According to an embodiment of the present invention, in a first aspect, a lighting control system is provided, Figure 1 As shown, it includes a brightness acquisition module 108, a voice acquisition module 109, a control chip 104 and a light module 110. The output ends of the brightness acquisition module 108 and the voice acquisition module 109 are respectively connected to the input end of the control chip 104, and the output end of the control chip 104 is connected to the controlled end of the light module 110. The brightness acquisition module 108 is used to detect the brightness of the surrounding environment and convert the brightness signal into an electrical signal. The voice acquisition module 109 is used to collect sounds in the surrounding environment and convert the volume signal into an electrical signal. The light module 110 is used to adjust the light brightness. The control chip 104 is used to receive the electrical signals transmitted by the brightness acquisition module 108 and the voice acquisition module 109, and determine whether to trigger the corresponding operation according to the preset conditions.

[0055] The brightness acquisition module 108 acquires the brightness of the surrounding environment and feeds back the brightness signal to the control chip 104. The control chip 104 compares the brightness signal value transmitted by the brightness acquisition module 108 with the set brightness threshold to determine whether the surrounding environment has become darker. When the brightness signal value transmitted by the brightness acquisition module 108 is lower than the brightness threshold, the control chip 104 determines that the surrounding environment has become darker. The voice acquisition module 109 acquires the sound in the surrounding environment and feeds back the sound signal to the control chip 104. The control chip 104 determines whether the sound in the surrounding environment is a uniform breathing sound. When the control chip 104 determines that the sound in the surrounding environment is a uniform breathing sound, the control chip 104 controls the lighting module 110 to reduce the brightness of the light.

[0056] The above-mentioned light control system, through the coordinated work of the brightness acquisition module 108 and the voice acquisition module 109, can be applied to smart plush toys, so that the smart plush toys can automatically adjust the light brightness when the surrounding environment is detected to be dark and the uniform breathing sound is recognized. This function is particularly suitable for single young people, and can provide them with soft light companionship at night, which helps to alleviate loneliness and enhance a sense of security. Unlike traditional smart plush toys with mechanical structures, the present invention does not rely on motors and mechanical structures to achieve interactive functions, which not only reduces the complexity and potential failure points of the product, but also makes the product lighter, softer, and more suitable for adult use.

[0057] The above-mentioned lighting control system, through the combination of brightness acquisition module 108 and voice acquisition module 109, can intelligently perceive the changes in surrounding brightness and sound, and respond accordingly based on this information. For example, at night when the room becomes dark and the user's even breathing sound is detected, the light brightness is automatically reduced to prevent sudden strong light from disturbing the user's sleep. Since it is driven by sensors rather than mechanically, the overall system has low power consumption, which extends the product's battery life and improves the user's experience.

[0058] The above-mentioned lighting control system can respond to user voice commands through the voice acquisition module, such as playing soothing music or stories, further enhancing the interactivity of the product.

[0059] In some embodiments, the control chip 104 has a built-in digital signal processor (DSP), which is used to pre-process the sound signal, extract time domain and frequency domain features, classify the features, and determine whether it is a uniform breathing sound.

[0060] More specifically, the digital signal processor includes a preprocessing module, a feature extraction module and a feature classification module. The preprocessing module is used to filter and reduce noise on the original audio data before feature extraction to remove noise and optimize signal quality. The feature extraction module is used to extract time domain and frequency domain features from the preprocessed sound signal. Common methods for extracting time domain include short-time energy, zero crossing rate, etc. Common methods for extracting frequency domain features include Fourier transform method, which converts time domain signals into frequency domain signals and analyzes their frequency components. The feature classification module is used to classify the extracted time domain and frequency domain features using trained machine learning models. These models can be trained with a large amount of labeled data to distinguish different types of breathing sounds (such as uniform breathing, uneven breathing, speaking, etc.). Then, when the digital signal processor determines that the external sound is a uniform breathing sound, the corresponding operation is triggered to control the lighting module 110 to reduce the brightness; if the digital signal processor determines that the external sound is not a uniform breathing sound, the original state is maintained or further analyzed.

[0061] In this embodiment, compared with simple volume detection, the digital signal processor can effectively distinguish background noise and other non-breathing sounds through in-depth analysis of the sound signal, thereby improving the accuracy of breathing sound recognition and reducing the possibility of misjudgment. When the digital signal processor confirms that the sound in the surrounding environment is a uniform breathing sound, the control chip 104 will trigger the lighting module 110 to reduce the brightness. This function is particularly useful at night. It can automatically dim the lights after the user falls asleep to avoid strong light interfering with sleep and provide a more comfortable sleeping environment.

[0062] In some embodiments, the lighting control system further includes a sound module 105. When the control chip 104 determines that the sound in the surrounding environment is a uniform breathing sound, the control chip 104 controls the sound module 105 to start playing pre-stored sleep-aiding white noise. White noise is a sound signal with a wide spectrum that can mask other noises in the environment, helping the user fall asleep faster and maintain a good sleep quality. The volume and frequency of white noise can be adjusted according to the user's preferences to ensure the most comfortable sleep-aiding effect.

[0063] In this embodiment, the lighting control system realizes intelligent recognition and response to breathing sounds by integrating the sound module 105. When the control chip 104 determines that the sound in the surrounding environment is a uniform breathing sound, the system will automatically play white noise to help sleep, thereby creating a more comfortable and quiet sleeping environment and improving the overall experience of the user.

[0064] More specifically, the sound module 105 includes a power amplifier module and a speaker. The power amplifier module is responsible for amplifying the audio signal from the control chip 104 so that it has enough power to drive the speaker to make sound. The speaker is the sound-generating component of the sound module 105, which is responsible for converting the electrical signal output by the power amplifier module into sound waves and transmitting them to the user. The sound module 105 is connected to the control chip 104 through a DAC (digital-to-analog converter), which is used to convert the digital audio signal generated by the control chip 104 into an analog audio signal so that the power amplifier module and the speaker can process and play these audio signals.

[0065] In some embodiments, the control chip 104 has a built-in timer. When the control chip 104 detects that the sound in the surrounding environment is a uniform breathing sound through a digital signal processor (DSP), the system enters the sleep-aiding mode. The control chip 104 sends an instruction to the light module 110 to gradually reduce the light brightness, and at the same time, the control chip 104 controls the sound module 105 to play sleep-aiding white noise. When the brightness of the light module 110 is reduced to a predetermined level and the sound module 105 starts playing white noise, the built-in timer is activated and starts timing. The timer can pre-set a time period. When the timer reaches the set time, the control chip 104 will send an instruction to the light module 110 to completely turn off the light. At the same time, the control chip 104 will also send an instruction to the sound module 105 to stop playing sleep-aiding white noise.

[0066] In this embodiment, through the built-in timer, the control chip 104 can maintain a low light brightness and sleep-aiding white noise for a period of time after the user falls asleep. When the preset time is reached, the light is automatically turned off and the white noise playback is stopped. This not only improves the intelligence level of the system, but also ensures that the user has a more comfortable and quiet sleeping environment at night, while avoiding long-term unnecessary energy consumption.

[0067] In some embodiments, the brightness acquisition module is an optocoupler resistor. An optocoupler resistor is a photoelectric conversion element that can convert the received light intensity into a corresponding resistance value change. When the ambient light intensity changes, the resistance value of the optocoupler resistor will change accordingly. The optocoupler resistor is transmitted to the control chip via an ADC signal.

[0068] In some embodiments, the voice collection module is a MIC, which transmits the ADC signal to the control chip.

[0069] According to an embodiment of the present invention, a second aspect provides an intelligent toy, Figures 1 to 3 As shown, the toy comprises a toy body 200 and a light control system. The light control system is arranged inside the toy body 200. In this embodiment, the light control system is applied to the toy, and the light control system is responsible for controlling the light effects on the toy to enhance the user's visual experience and interactivity.

[0070] In some embodiments, a posture sensor 102 is provided on the toy body 200. The posture sensor 102 is used to convert the posture signal and acceleration signal of the toy body 200 into electrical signals, and provide IIC transmission to the control chip 104. The control chip 104 analyzes the current signal characteristics, determines the current action, and plays the corresponding audio through the sound module 105 according to the frequency, duration and amplitude of the shaking. The audio signal is transmitted to the power amplifier chip through the ADC signal, and the power amplifier chip drives the speaker to emit sound. The posture sensor 102 includes a three-axis gyroscope and a three-axis accelerometer. The three-axis gyroscope is used to measure the rotation angle of the toy body 200 in three axes and provide accurate posture information. The three-axis accelerometer is used to measure the acceleration of the toy body 200 in three axes to help identify the motion state of the toy (such as tilting, flipping, shaking, etc.).

[0071] In some embodiments, the toy body 200 includes a toy head 201, a toy body 202, toy arms 203, toy legs 204, and a head cap 205. The toy head 201 has toy ears. The gesture sensor 102 is disposed inside the toy body. The light control system is disposed on the toy head 201.

[0072] In some embodiments, a touch sensor or a carbon film button 101 is provided on the toy body. More specifically, the touch sensor or the carbon film button 101 is provided at the end of the toy arm 203 and / or the toy head 201 and / or between the toy body 202 and the toy arm 203. When the touch sensor or the carbon film button 101 is touched, the touch sensor or the carbon film button 101 feeds back the touch information to the control chip 104, so that the control chip 104 controls the sound module 105 to play the corresponding offline voice.

[0073] In some embodiments, the toy ear is provided with a tension sensor 106. When the toy ear is pulled, the tension sensor 106 feeds back the tension information to the control chip 104, so that the control chip 104 controls the sound module 105 to play the corresponding offline voice.

[0074] In some embodiments, the head cap 205 is provided with a flap light 103 which emits a bright light when the flap light 103 is touched.

[0075] In some embodiments, a zipper bag is provided inside the toy body, and the zipper bag is used to store items.

[0076] In some embodiments, the toy body 202 is provided with a temperature sensor 107, which is used to detect the temperature state of the external environment and feed back the temperature information to the control chip 104, so that the control chip 104 controls the sound module 105 to play the temperature information. The temperature sensor 107 can detect the temperature of the external environment in real time and feed back the temperature information to the control chip 104. The sound module 105 selects a suitable audio file from the stored offline voice library for playback according to the instructions of the control chip 104.

[0077] In some embodiments, the control chip 104 is wirelessly connected to the mobile phone APP, and the control chip 104 can transmit the temperature information detected by the temperature sensor 107 to the mobile phone APP, thereby facilitating the user to intuitively view the temperature information.

[0078] In some embodiments, the control chip 104 has a built-in real-time alarm module, and the user can control the time of the real-time alarm module through voice.

[0079] In addition, the above-mentioned smart toy also has a power button, a reset button, an 800mA battery, a charging detection module, a type-C interface, a head button, a body hug button and other structures. The 800mA battery is used to power the entire smart toy. When the user hugs the smart toy, the body hug button will be touched, which will trigger the corresponding voice.

[0080] The control chip 104 of the above-mentioned intelligent toy has an interactive dialogue mode, a soothing mode, a relaxing mode, a sleeping mode, and a sleep disturbance prevention mode. The interactive mode includes a voice interactive mode and an action interactive mode.

[0081] The specific operation process of the action interaction mode of the above-mentioned smart toy is as follows:

[0082] S1. When the smart toy is turned on and in interactive mode, the user interacts with the smart toy. For example, touching the nose, touching the cheek, hugging the body, pressing the palm of the toy, etc., will directly trigger the touch sensor or carbon film button 101, and the touch sensor or carbon film button 101 will be squeezed to feedback the touch information to the control chip.

[0083] S2. The control chip determines the user action according to the current signal source and plays the corresponding offline voice.

[0084] For example, when the nose or armpit of the smart toy is touched, the touch sensor or carbon film button will be triggered, and the smart toy will issue a ticklish dialogue "Ha, it's so itchy, hahaha, hehe", "They say that being ticklish means being afraid of your wife, but I'm the wolf king, I'm not afraid... hahaha, hehe, it's so itchy, I surrender, stop now".

[0085] When the cheek of the smart toy is touched, the touch sensor or carbon film button will be triggered, and the smart toy will make snoring and heartbeat sounds.

[0086] When the smart toy is hugged tightly, the touch sensor on the toy body 202 will be triggered, and the smart toy will utter sweet words, such as "You are the most important person to me."

[0087] When the flapping light 103 of the head cap 205 is flapped, the flapping light 103 of the intelligent toy lights up.

[0088] The specific operation process of the voice interaction mode of the above-mentioned smart toy is as follows:

[0089] S10. When the smart toy is turned on and in the interactive mode, the user and the smart toy can have a conversation or chat.

[0090] S20. The voice collection module 109 converts the sound signal into an electrical signal and transmits it to the control chip, which saves the sound information and sends it to the cloud.

[0091] S30. Under the premise of step S20, if the connection to the cloud fails, the control chip matches the sound signal with the offline wake-up word. If the match is successful, the sound module plays the corresponding offline voice. If the match fails, the network connection disconnection prompt tone is played.

[0092] S40. Under the premise of step S20, if the connection to the cloud is successful, after receiving the return signal from the cloud, the corresponding network audio is downloaded, and the downloaded audio is played through the sound module.

[0093] For example, calling the name of a smart toy will wake it up actively; starting a corresponding conversation based on the tone and characteristic language.

[0094] The specific operation process of the soothing mode of the above-mentioned smart toy is as follows:

[0095] When the user sighs, cries, sobs, screams, or says specific words such as "I'm so sad / heartbroken", "I'm not happy", etc., the control chip recognizes the voice information and then controls the sound module to play words of encouragement and comfort.

[0096] Alternatively, when the smart toy's head or body is violently slapped or violently shaken, the gesture sensor detects the shaking action, and the gesture sensor feeds the shaking action back to the control chip, which controls the sound module to play encouraging and comforting words.

[0097] The specific operation process of the sleep mode of the above-mentioned smart toy is as follows:

[0098] When the user yawns or says specific words such as "I'm sleepy, I want to sleep, good night", the control chip 104 controls the light module 110 to reduce the light brightness and simultaneously controls the sound module 105 to emit white noise to help sleep.

[0099] Alternatively, when the brightness of the surrounding environment is lower than the set brightness threshold, the control chip 104 determines that the surrounding environment has become darker; the voice collection module 109 collects the sounds in the surrounding environment, and when the user makes a uniform breathing sound, the control chip 104 determines whether the sound in the surrounding environment is a uniform breathing sound. The control chip 104 controls the light module 110 to reduce the light brightness, and at the same time controls the sound module 105 to emit sleep-aiding white noise.

[0100] The specific operation process of the sleep anti-disturbance mode of the above-mentioned smart toy is as follows:

[0101] After 30 minutes in the bedtime mode, the system enters the sleep anti-disturbance mode. The applet sets a fixed time for sleep do not disturb mode; AI develops habits for intelligent anti-disturbance. At this time, the control chip 104 controls the light module 110 to turn off the sound, and controls the sound module 105 to turn off the sound.

[0102] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
