A solution for child care using Zigbee technology monitors children's crying and determines the reasons behind infants' crying.
Project Background
When it comes to caring for newborns, especially for novice mothers, it is crucial to pay attention to the baby's health and safety in addition to meeting their basic needs such as feeding, diaper changing, and ensuring sufficient sleep. One common way infants express discomfort is through crying. However, due to various reasons such as maternal fatigue, illness, or social pressures, mothers often struggle to promptly recognize their baby's cries. This can result in prolonged discomfort for the baby and increased caregiving pressure for the new mothers.
To assist novice mothers in taking better care of their babies, the client has collaborated with the ZedIoT team to develop a crucial smart device that can monitor infant crying in real time. This device should have accurate detection capabilities, support remote monitoring, be compact and user-friendly, and prioritize security and privacy protection. It will serve as an efficient, precise, user-friendly, and highly practical smart healthcare device.
Project Requirements
Our Solution
Based on the requirements mentioned above, this is a typical application where user data is collected and accessed through a mobile phone. We will implement the solution using the Tuya Zigbee scheme. The main tasks involved are as follows:
1. Hardware Design: The initial step is to design the hardware, which includes modules for collecting children's crying sounds, signal processing, and the Tuya Zigbee module. Hardware design must consider aspects such as power supply safety.
2. Sound Collection: Children's crying sounds are collected using a microphone module. During the data collection process, careful design of filters and other signal processing algorithms is necessary to reduce interference from environmental noise.
3. Signal Processing: Signal processing is the core of the entire product. It involves multi-level signal analysis and feature extraction from the collected sound data. Accurate determination of whether the child is crying is achieved through algorithms such as machine learning and deep neural networks. The information is then quickly communicated to the parents' mobile phones.
4. Communication Module Design: Using the Tuya Zigbee module, the detection results are sent to the parents' mobile phones or other specified devices, enabling parents to promptly understand the child's situation. Additionally, the design and development of the mobile application should provide an enhanced user experience.
5. Testing and Improvement: After the development of the child crying monitoring device, comprehensive testing is conducted, including performance testing and user experience testing. Based on the test results and user feedback, continual improvement of the product design and performance is carried out to enhance reliability and stability.
