Description

Technical Field

[0001] This invention relates to the field of monitoring system technology, specifically to a children's room monitoring system and its application method. Background Technology

[0002] With societal development and an increasingly fast-paced lifestyle, it is becoming increasingly difficult for family members to accompany infants and toddlers around the clock. In this context, finding a method to ensure infant and toddler safety and provide real-time monitoring has become crucial. Camera-based infant and toddler monitoring systems were developed specifically to address this need. By monitoring the infant's living environment and physiological condition, they provide parents with real-time information, enabling them to detect and address potential safety hazards immediately.

[0003] However, most existing smart child monitoring products rely on sensor-collected information for simple information processing and logical judgment, making it difficult to identify and handle complex scenarios and meet the real-world child care needs. To address these issues, some products attempt to utilize deep learning algorithms for intelligent perception and decision-making, such as patent CN202210556558.2. However, deep learning algorithms are resource-intensive, and most products can only transmit the monitored images and sounds to a cloud server for inference before downloading the results back to the device. This means that monitoring functions fail entirely when the network is unstable. Even when the network is stable, there are concerns about data leakage.

[0004] Most child monitoring devices on the market use a combination of user devices and cloud services.

[0005] User equipment includes a high-definition camera, a sound sensor, an environmental sensor, and a wireless communication module. The high-definition camera provides real-time video streaming and image capture, and should support night vision for monitoring in low-light conditions. The sound sensor monitors the child's voice and movement to notify parents when the child cries. The environmental sensor monitors room temperature, humidity, and air quality to ensure a suitable environment in the child's room. The wireless communication module transmits data to a cloud server. In addition, there may be a display or mobile application allowing parents to easily access and control the monitoring system, receive cloud-based alarm information, etc.

[0006] The cloud service includes a cloud-based data processing platform with capabilities for real-time video stream processing, data analysis, and historical data storage and retrieval. Real-time video stream processing receives and stores live video streams transmitted from cameras, making them available for parents to view. Data analysis, through real-time analysis of sensor data, identifies children's behavioral patterns, such as sleeping, waking, and crying, and sends appropriate notifications based on the analysis results. Historical data storage and retrieval stores sensor data on a cloud server, allowing parents to access historical data when needed.

[0007] To protect the privacy of infants and families, data encryption and access control are employed during data upload and storage. Data encryption means that all data transmitted to the cloud server should be encrypted to prevent interception during transmission. Access control ensures that only authorized users can access video streams and sensor data. Applications should use secure login mechanisms, such as two-factor authentication.

[0008] The above solution is a popular technology for infant and toddler monitoring devices that can provide comprehensive infant and toddler monitoring services while protecting user privacy and data security to the greatest extent possible.

[0009] While cloud-based children's room monitoring systems have many advantages, such as easy access and stable data storage, they also have some potential drawbacks.

[0010] The activation process is not intelligent: With existing child monitoring systems, parents need to approach the screen and tap to activate the monitoring function or open the accompanying software. This adds to the burden for many parents who have just put their children to sleep and are already tired.

[0011] Privacy concerns: Any information transmitted over the internet is at risk of being illegally intercepted and used. Although many cloud service providers employ encryption technologies to protect data security, data breaches can still lead to the violation of children's and families' privacy.

[0012] Network dependency: Cloud-based monitoring systems require a stable network connection to function properly. Network problems or slow speeds may affect real-time video transmission and data uploads.

[0013] Data ownership: Using cloud services means your data is stored on the service provider's servers. While most service providers promise to protect user data security and privacy, users' control over their data is diminished to some extent.

[0014] Cost: Many cloud service providers charge for storage space and data transfer volume. If you require long-term video recording and storage, you may need to pay additional fees.

[0015] System Availability: The stability and availability of cloud services depend on the service provider. If the service provider's servers fail, the monitoring system may not function properly.

[0016] Therefore, a new solution is needed to address the above problems. Summary of the Invention

[0033] S2: A gesture is predefined in the AI ​​box, which corresponds to the activation of the monitoring function. The predefined gesture and the child are detected by the detection model deployed in the AI ​​box. At the same time, a sound classification model is deployed in the AI ​​box to classify crying, mild cough, cough of typical disease type and laughter.

[0034] S3: The AI ​​box acquires images from the image sensor and sends them to the detection model. When a predefined gesture is detected, the child monitoring function is activated and the parents are prompted.

[0035] S4: After the child monitoring function is activated, the AI ​​box acquires images from the image sensor and sends them to the detection model. When it detects a drastic change in the child's position or detects crying, it automatically plays the voice or music recorded by the guardian to soothe the child. If a predefined gesture is detected again, the child monitoring function will be deactivated.

[0036] S5: During device operation, the AI ​​box acquires sound from the sound sensor and sends it to the sound classification model. When the sound classification result is laughter, it automatically saves the corresponding sound and image as a memory recording. When the detection result is crying and the child monitoring function is enabled, it automatically plays the voice or music recorded by the guardian to soothe the child. When a typical disease-related cough is detected, it plays a medical reminder. When a mild cough is detected, it records the time of the cough to count the frequency of coughs.

[0037] Compared with the prior art, the beneficial effects of the present invention are:

[0038] This invention enables parents to activate and deactivate child monitoring functions based on gestures through corresponding system settings. This more intelligent control method frees up parents, ensuring that image and sound data remain on the device throughout the process, completely eliminating the risk of data leakage. It also facilitates the addition of laughter detection, cough statistics, and typical disease-related cough detection in daily monitoring, making it convenient for daily monitoring of children while also assisting in the management of children's health.
