摘要
随着酒店行业对服务质量和安全保障要求的不断提升，夜间环境的智能化管理成为重要发展方向。酒店夜间若存在温度异常未能及时预警，或光照不足影响客人行动等问题，会降低客人居住体验，甚至可能引发安全事故。因此，研发一种能实现酒店夜间自动照明控制与异常温度报警的系统具有重要意义。
本设计提出了一种基于 STM32F103C8T6 单片机的酒店夜间自动照明和报警控制系统。系统主要功能包括：通过 DS18B20 温度监测模块实时监测当前酒店房间或公共区域的环境温度，当温度大于预设最大值时，系统启动声光报警进行提醒；借助 5516 光照检测模块监测环境光照强度，当光照强度小于预设最小值时，自动控制 LED 照明灯打开，为客人提供适宜光照；利用单片机内部 RTC（实时时钟）获取当前时间，用户可通过按键对时间进行修正，同时也能通过按键设置定时开关灯功能，满足酒店不同时段的照明需求；通过 OLED 显示屏清晰显示实时环境温度、光照强度以及是否发生火灾（温度异常触发报警时对应火灾预警状态），方便工作人员实时掌握环境情况。
该酒店夜间自动照明和报警控制系统的作用在于，为酒店夜间管理提供了一种智能化、自动化的解决方案。通过自动照明控制提升客人夜间居住的便利性与舒适度，通过异常温度报警及时防范火灾等安全风险，有助于提升酒店的服务水平和安全保障能力，为客人营造安全、舒适的居住环境。

Based on STM32 Hotel Night Automatic Lighting and Alarm Control System
Abstract
With the continuous improvement of service quality and safety requirements in the hotel industry, intelligent management of nighttime environments has become an important development direction. If there are temperature anomalies in the hotel at night that are not promptly alerted, or if there is insufficient lighting that affects guests’ movements, it can reduce their living experience and even lead to safety accidents. Therefore, it is of great significance to develop a system that can achieve automatic night lighting control and abnormal temperature alarm in hotels.
This design proposes a hotel night time automatic lighting and alarm control system based on STM32F103C8T6 microcontroller. The main functions of the system include: real-time monitoring of the ambient temperature in the current hotel room or public area through the DS18B20 temperature monitoring module. When the temperature exceeds the preset maximum value, the system will activate an audible and visual alarm for reminder; By using the 5516 light detection module to monitor the ambient light intensity, when the light intensity is less than the preset minimum value, the LED lighting is automatically controlled to turn on, providing suitable lighting for guests; By using the internal RTC (Real Time Clock) of the microcontroller to obtain the current time, users can adjust the time by pressing buttons, and also set the timed on/off light function by pressing buttons to meet the lighting needs of the hotel at different times; Clear display of real-time environmental temperature, light intensity, and whether a fire has occurred (corresponding to the fire warning status triggered by abnormal temperature) through OLED display screen, making it convenient for staff to grasp the environmental situation in real time.
The function of the hotel’s night time automatic lighting and alarm control system is to provide an intelligent and automated solution for hotel night time management. By using automatic lighting control to enhance the convenience and comfort of guests’ nighttime living, and by promptly preventing safety risks such as fires through abnormal temperature alarms, it helps to improve the hotel’s service level and security capabilities, creating a safe and comfortable living environment for guests.
