摘要
在安全防范领域，实时有效的监控、异常情况的及时预警及历史数据的可靠存储，对保障人员与财产安全至关重要。传统的监控系统常存在布线复杂、实时性差、历史数据调取不便等问题，难以满足高效安全监控的需求。
基于 STM32F103C8T6 单片机的视频监控系统，整合了时钟模块、摄像头、SD 卡、人体热释电传感器、显示模块及按键，实现了对监控场景的实时监控、异常预警与信息管理。系统核心功能包括：通过时钟模块获取当前时间；借助摄像头将实时画面上传至手机 APP，并将历史数据存储于 SD 卡，支持历史数据查看；利用人体热释电传感器检测环境中是否有人，布防状态下检测到人时进行声光报警；通过按键校准时间及进行布防、撤防操作；通过显示模块展示时间及布防、撤防状态。
该系统的实现，有效提升了监控的智能化与便捷性，通过实时画面传输、异常自动预警、历史数据存储及便捷的操作控制，为安全监控提供了可靠保障，同时为视频监控领域的智能化发展提供了参考，具有较高的实用价值与推广意义。

ABSTRACT
In the field of security and protection, real-time and effective monitoring, timely early warning of abnormal situations, and reliable storage of historical data are crucial for ensuring the safety of personnel and property. Traditional monitoring systems often have problems such as complex wiring, poor real-time performance, and inconvenient retrieval of historical data, making it difficult to meet the needs of efficient security monitoring.
The video surveillance system based on the STM32F103C8T6 microcontroller integrates a clock module, camera, SD card, human body pyroelectric sensor, display module, and buttons, realizing real-time monitoring, abnormal warning, and information management of the monitoring scene. The core functions of the system include: obtaining the current time through the clock module; uploading real-time images to the mobile phone APP with the help of the camera, and storing historical data in the SD card to support the viewing of historical data; using the human body pyroelectric sensor to detect whether there is a person in the environment, and triggering an acousto-optic alarm when a person is detected in the armed state; calibrating the time and performing arming and disarming operations through buttons; displaying the time and the arming/disarming status through the display module.
The implementation of this system has effectively improved the intelligence and convenience of monitoring. Through real-time image transmission, automatic abnormal warning, historical data storage, and convenient operation control, it provides a reliable guarantee for security monitoring. At the same time, it provides a reference for the intelligent development of the video surveillance field and has high practical value and promotion significance.
