基于 STM32F103C8T6 的物联网施工防侵限监测系统设计
在施工过程中，各类人员或物体的非法入侵可能会干扰施工秩序、引发安全事故，对施工安全和进度造成严重影响。因此，研发一套能够实时监测施工区域入侵情况、及时预警的系统具有重要意义。
本设计提出了一种基于 STM32F103C8T6 单片机的物联网施工防侵限监测系统，系统分为从机和主机两部分。从机通过 4 位拨码开关区分不同坐标，借助红外避障管检测是否有人员或物体入侵，在布防状态下检测到入侵时，会自动进行声光报警，并将相关数据通过蓝牙发送至主机；主机可通过蓝牙接收从机数据，若收到报警提示则同步声光报警并显示入侵从机坐标号，同时利用内部 RTC 获取时间，支持通过 3 个按键修正时间且在检测到入侵时自动锁定时间，还可通过按键切换布防与撤防模式，通过 OLED 显示屏展示各类信息。
该物联网施工防侵限监测系统的作用在于，为施工区域提供了实时、可靠的入侵监测与预警手段。通过及时发现入侵行为并发出警报，能够有效防范安全风险，保障施工区域的安全，维护施工秩序，确保施工工作顺利推进。

Design of IoT-based Construction Intrusion Limitation Monitoring System Based on STM32F103C8T6
Abstract
During the construction process, illegal intrusion of various personnel or objects may disrupt the construction order, cause safety accidents, and have a serious impact on construction safety and progress. Therefore, it is of great significance to develop a system that can real-time monitor the intrusion situation in the construction area and provide timely early warning.
This design proposes an IoT-based construction intrusion limitation monitoring system based on the STM32F103C8T6 single-chip microcomputer. The system is divided into two parts: slave machine and master machine. The slave machine distinguishes different coordinates through a 4-bit DIP switch and detects whether there is personnel or object intrusion by means of an infrared obstacle avoidance tube. When an intrusion is detected in the armed state, it will automatically give an audible and visual alarm and send relevant data to the master machine via Bluetooth; the master machine can receive data from the slave machine through Bluetooth. If an alarm prompt is received, it will synchronously give an audible and visual alarm and display the coordinate number of the intruding slave machine. At the same time, it uses the internal RTC to obtain time, supports time correction through 3 keys and automatically locks the time when an intrusion is detected. It can also switch between armed and disarmed modes through keys and display various information through an OLED display screen.
The function of this IoT-based construction intrusion limitation monitoring system is to provide a real-time and reliable intrusion monitoring and early warning method for the construction area. By timely detecting intrusion behaviors and issuing alarms, it can effectively prevent safety risks, ensure the safety of the construction area, maintain the construction order, and ensure the smooth progress of construction work.
