摘要

在儿童成长过程中，良好的行为习惯和学习环境对其身心健康发展至关重要。传统的儿童行为监测多依赖家长人工看管，不仅耗费大量精力，还存在监测不及时、提醒滞后等问题，难以有效规范儿童行为和保障学习环境稳定。

基于 STM32F103C8T6 单片机的儿童监测系统，整合了 HX711 压力检测模块、D203S 人体热释电感应模块、MPU6050 姿态传感器、康帕斯 A9 摄像头、OLED 显示屏、ESP8266WiFi 模块及 CN-TTS 语音播报模块等，实现了对儿童行为及周边环境的自动化监测与智能提醒。系统核心功能包括：通过 HX711 检测儿童压力变化，10 秒内变化超过 3 次判定为多动时，触发语音提醒；借助 D203S 检测儿童是否走动，检测到走动后进行语音播报提醒；利用 MPU6050 监测桌面晃动，出现晃动时发出语音提醒；通过康帕斯 A9 摄像头采集画面并传输至手机端；OLED 显示屏实时显示各项监测状态数据；ESP8266WiFi 模块将数据发送至手机端，方便家长远程查看；CN-TTS 语音播报模块负责各类提醒信息的语音输出。

该系统的实现，有效减轻了家长的看管压力，及时规范儿童行为，保障了稳定的学习环境，为儿童健康成长提供了有力支持，同时为同类儿童监测设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT

In the process of children's growth, good behavior habits and learning environment are crucial to their physical and mental health development. Traditional children's behavior monitoring mostly relies on parents' manual supervision, which not only consumes a lot of energy but also has problems such as untimely monitoring and delayed reminders, making it difficult to effectively regulate children's behavior and ensure a stable learning environment.

The child monitoring system based on the STM32F103C8T6 microcontroller integrates HX711 pressure detection module, D203S human body pyroelectric induction module, MPU6050 attitude sensor, Compas A9 camera, OLED display, ESP8266WiFi module and CN-TTS voice broadcast module, etc., realizing automatic monitoring and intelligent reminder of children's behavior and surrounding environment. The core functions of the system include: detecting children's pressure changes through HX711, triggering voice reminders when it is judged as hyperactivity if the change exceeds 3 times within 10 seconds; detecting whether the child is walking with D203S, and conducting voice broadcast reminders after detecting walking; monitoring desktop shaking with MPU6050, and issuing voice reminders when shaking occurs; collecting images through Compas A9 camera and transmitting them to the mobile phone; OLED display showing various monitoring status data in real-time; ESP8266WiFi module sending data to the mobile phone for parents to check remotely; CN-TTS voice broadcast module being responsible for voice output of various reminder information.

The implementation of this system effectively reduces the supervision pressure of parents, timely regulates children's behavior, ensures a stable learning environment, provides strong support for children's healthy growth, and also provides a reference for the research and development of similar child monitoring equipment, with high practical application value.
