随着校园生活的日益丰富，学生对于时间管理和作息规律的需求愈发强烈，传统的作息时间提醒方式已无法满足现代校园的需求。为了提供更加智能化、便捷化的时间管理方案，本设计致力于校园时间作息系统的研究与实现。
本系统以STM32F103C8T6单片机为核心控制器，通过时钟模块能够实时获取当前时间，并支持闹钟设置，帮助学生合理规划学习与休息时间；利用DS18B20温度传感器实时监测环境温度，为校园生活提供舒适度的参考。通过烟雾传感器及时发现潜在的安全隐患，一旦烟雾浓度超过预设阈值，系统将启动声光报警，确保校园安全。通过人体热释电感应模块在布防状态下能够检测非法闯入，有效防范校园盗窃等安全问题。系统还配备了4*4矩阵键盘，支持密码开锁功能，密码错误时将进行声光报警提醒，同时提供报警取消功能，增强系统的灵活性和实用性。所有信息均可以通过OLED显示屏实时展示，方便学生随时查看系统状态。实物测试表明，该系统各项功能均已实现，运行稳定可靠，性价比高，不仅满足了学生对于时间管理和作息规律的需求，还提升了校园生活的智能化水平，具有广阔的发展前景。

Title Design And Implementation of Campus Time Work And Rest System
With the increasing richness of campus life, students’ demand for time management and work and rest rules has become increasingly strong. The traditional work and rest time reminder method has been unable to meet the needs of modern campus. In order to provide a more intelligent and convenient time management scheme, this design is committed to the research and implementation of campus time work and rest system.
The system uses stm32f103c8t6 microcontroller as the core controller. The current time can be obtained in real time through the clock module, and the alarm clock setting is supported to help students plan their study and rest time reasonably; The DS18B20 temperature sensor is used to monitor the ambient temperature in real time, providing a reference for the comfort of campus life. Through the smoke sensor, potential security risks can be found in time. Once the smoke concentration exceeds the preset threshold, the system will start the audible and visual alarm to ensure the safety of the campus. The pyroelectric induction module of human body can detect illegal intrusion in the armed state, and effectively prevent campus theft and other security problems. The system is also equipped with a 4*4 matrix keyboard, which supports the password unlocking function. When the password is wrong, audible and visual alarm will be given, and the alarm cancellation function will be provided to enhance the flexibility and practicability of the system. All information can be displayed in real time through the OLED display, which is convenient for students to view the system status at any time. The physical test shows that all functions of the system have been realized, the operation is stable and reliable, and the cost performance is high. It not only meets the needs of students for time management and work and rest rules, but also improves the intelligent level of campus life, and has broad development prospects.
