Description

Technical Field

[0001] This utility model relates to the field of infant care technology, and in particular to an infant care system that can use AI to recognize infant emotions and automatically capture images. Background Technology

[0002] The applicant previously filed a Chinese invention application, CN120017956A, entitled "An Infant Care System with Camera Function," which includes a camera module for real-time acquisition of infant video data; a sound acquisition module for acquiring environmental sound data; a display with switchable monitoring and image display modes; a storage module; and a control unit for receiving infant video data acquired by the camera module and environmental sound data acquired by the sound acquisition module. The control unit includes an AI algorithm module, which deploys, for example, a convolutional neural network (CNN) trained model, and the dataset contains infant smiling face samples and crying sound samples.

[0003] During video surveillance, the system automatically captures happy moments of the baby and generates an electronic photo album, automatically recording the baby's happy growth without requiring manual shooting by the user. Furthermore, during the capture process, it performs dual verification of smile recognition and crying sound identification to reduce false captures and improve the accuracy of the recording.

[0004] However, since the camera module is usually fixed in a certain position or area, when relying on video images and sound to jointly identify infant emotions, there are situations where the camera module cannot capture the infant's facial expressions after the infant rolls over, which makes it impossible to accurately perform multi-sensor recognition. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this invention aims to provide an AI-powered infant care system that can accurately identify and automatically capture an infant's emotions even when the camera module is unable to capture the infant's facial expressions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an infant care system capable of AI-based recognition of infant emotions and automatic image capture, comprising... The baby monitor includes a first wireless module, a first memory module, a first control unit, a sound acquisition module, and a camera for filming the baby. The monitoring terminal display has a second wireless module, a second memory module, a second control unit, and a display unit. The second control unit has an AI chip. The baby monitor also has a vibration detection module for detecting the baby's vibration frequency. The signal output terminal of the vibration detection module is electrically connected to the signal input terminal of the first control unit. The first control unit transmits wireless signals to the second control unit through the first wireless module and the second wireless module.

[0007] A further technical solution of this utility model: The vibration detection module includes a vibration sensor.

[0008] A further technical solution of this utility model: The baby monitor includes a monitor mounting base, a first viewing angle direction adjustment module is provided on the monitor mounting base, a first mounting bracket is installed on the adjustment end of the first viewing angle direction adjustment module, and a camera and a vibration sensor are installed on the first mounting bracket.

[0009] A further technical solution of this utility model: A second viewing angle adjustment module is also provided on the monitor mounting base, and a second mounting bracket is installed on the adjustment end of the second viewing angle adjustment module. The first viewing angle adjustment module is installed on the second mounting bracket on the monitor mounting base.

[0010] A further technical solution of this utility model: the first viewing angle direction adjustment module is configured to rotate and adjust the position and orientation of the first mounting bracket with the x-axis as the rotation axis, and the second viewing angle direction adjustment module is configured to rotate and adjust the position and orientation of the second mounting bracket with the y-axis as the rotation axis.

[0011] A further technical solution of this utility model: The first viewing angle adjustment module includes a first motor mounted on a second mounting bracket, the first motor being used to drive the first mounting bracket to rotate.

[0012] A further technical solution of this utility model: The second viewing angle adjustment module includes a second motor installed on the monitor mounting base, the second motor being used to drive the second mounting bracket to rotate.

[0013] A further technical solution of this utility model: The baby monitor also has a vibration shielding circuit, which pauses the vibration detection module when the camera's shooting angle is adjusted by rotation.

[0014] A further technical solution of this utility model: the vibration shielding circuit is configured such that when the first control unit controls the motor to be powered on and rotates, the vibration detection module is in a stopped power-on state.

[0015] Compared with the prior art, the beneficial effects of this technical solution are: the first control unit can wirelessly transmit the captured images, collected sounds and detected vibration signals to the second control unit, which then determines the baby's state; when the camera fails to capture the baby's facial expressions, the second control unit can still determine the baby's state based on the vibration and sound signals, enabling more accurate subsequent control, such as wirelessly controlling the baby monitor to capture photos.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 An infant care system that can recognize infant emotions and automatically capture images using AI includes an infant monitor 1 and a caregiver display 2.

[0021] The baby monitor 1 has a first wireless module 101, a first memory module 102, a first control unit 103, a sound acquisition module 104, and a camera 105 for filming the baby.

[0022] The monitoring terminal display 2 has a second wireless module 201, a second memory module 202, a second control unit 203 and a display unit 204, and the second control unit 203 has an AI chip.

[0023] The baby monitor 1 also has a vibration detection module 106 for detecting the vibration frequency of the baby. The signal output terminal of the vibration detection module 106 is electrically connected to the signal input terminal of the first control unit 103. The first control unit 103 transmits wireless signals to the second control unit 203 through the first wireless module 101 and the second wireless module 201.

[0024] The first control unit 103 can wirelessly transmit the captured images, collected sounds, and detected vibration signals to the second control unit 203, which will then determine the baby's status. Even when the camera 105 fails to capture the baby's facial expressions, the second control unit 203 can still determine the baby's status based on the vibration and sound signals, enabling more accurate subsequent control, such as wirelessly controlling the baby monitor to capture photos.

[0025] For example, if the sound is identified as crying and the vibration signal corresponds to a long vibration frequency, it is determined to be an infant crying; if the sound is identified as crying and the vibration signal corresponds to a no vibration frequency, it is determined to be a non-infant crying.

[0026] For example, if the sound is identified as laughter and the vibration signal corresponds to a rapid series of short vibrations, it is determined to be a baby's laughter; if the sound is identified as laughter and the vibration signal corresponds to a vibration frequency without vibration, it is determined to be a non-baby's laughter.

[0027] In some embodiments, the vibration detection module 106 includes a vibration sensor.

[0028] In some embodiments, the vibration sensor may be, for example, a ZD-A1 model vibration sensor capable of detecting minute vibrations.

[0029] In some embodiments, the vibration detection module 106 further includes a comparator. The comparator is, for example, an LM393.

[0030] In some embodiments, the baby monitor 1 includes a monitor mounting base 107, on which a first viewing angle adjustment module is provided, and a first mounting bracket 109 is mounted on the adjustment end of the first viewing angle adjustment module. A camera 105 and a vibration sensor are mounted on the first mounting bracket 109.

[0031] In some embodiments, a second viewing angle adjustment module is further provided on the monitor mounting base 107, and a second mounting bracket 111 is installed on the adjustment end of the second viewing angle adjustment module. The first viewing angle adjustment module is provided on the second mounting bracket 111 on the monitor mounting base.

[0032] In some embodiments, the first viewing angle adjustment module is configured to rotate and adjust the position and orientation of the first mounting bracket 109 with the x-axis as the rotation axis, and the second viewing angle adjustment module is configured to rotate and adjust the position and orientation of the second mounting bracket 111 with the y-axis as the rotation axis. The first and second viewing angle adjustment modules can correspondingly adjust multiple shooting angles of the camera 105, which is more conducive to the camera 105 capturing the infant's facial expressions.

[0033] In some embodiments, the second viewing angle adjustment module includes a second motor 110 mounted on the monitor mounting base 107. The second motor 110 is used to drive the second mounting bracket 111 to rotate, and is configured to rotate with the y-axis as the rotation axis.

[0034] In some embodiments, the first viewing angle adjustment module includes a first motor 108 mounted on a second mounting bracket 111. The first motor 108 is used to drive the first mounting bracket 109 to rotate, and is configured to rotate with the x-axis as the rotation axis.

[0035] In some embodiments, the baby monitor 1 also has a vibration shielding circuit 112, which pauses the vibration detection of the vibration detection module 106 when the camera 105 is rotated to adjust the shooting angle, so as to avoid the vibration of the baby monitor itself being falsely detected by the vibration detection module during adjustment.

[0036] In some embodiments, the vibration shielding circuit 112 is configured to keep the vibration detection module 106 in a stopped-power state when the first control unit 103 controls the first motor 108 and / or the second motor 110 to operate and rotate, so that the vibration detection module 106 cannot provide vibration signals to the first control unit 103 during the process of the first control unit 103 controlling the first motor 108 and / or the second motor 110.

[0037] In some embodiments, the first control unit 103 includes a first motor control circuit 113 and a second motor control circuit 114. The first control unit 103 controls the first motor 108 to operate by energizing it through the first motor control circuit 113, thereby adjusting its rotation. The first control unit 103 controls the second motor 110 to operate by energizing it through the second motor control circuit 114, thereby adjusting its rotation.

[0038] like Figure 4 As shown, the vibration shielding circuit 112 includes transistors Q1 and Q2. The base of transistor Q1 is connected to the power supply circuit from the first motor to the first motor control circuit. When the first motor is energized, transistor Q1 conducts, grounding the power supply terminal VCC of the vibration detection module, thus stopping the vibration detection module from receiving power. The base of transistor Q2 is connected to the power supply circuit from the second motor to the second motor control circuit. When the second motor is energized, transistor Q2 conducts, grounding the power supply terminal VCC of the vibration detection module, thus stopping the vibration detection module from receiving power.

[0039] Whether the first motor is controlled alone, the second motor is controlled alone, or both motors are controlled simultaneously, the vibration shielding circuit 112 can stop the vibration detection module 106 from receiving power to ensure that false detections are avoided during the adjustment process.

[0040] In some embodiments, the monitor mount 107 may be mounted on the edge of the crib. When the baby is in the crib and moves, causing vibration, the crib vibrates in response to the baby's contact, and the vibration detection module can detect a vibration signal that represents the baby's vibration.

[0041] In some embodiments, the baby monitor also has an infrared module 115 for use in conjunction with a camera 105 for nighttime shooting, which enables nighttime shooting by actively emitting invisible infrared light and receiving reflected light for imaging.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
