针对居家及社区养老中老人监护响应滞后、定位不便以及突发疾病无法及时呼救、易走失等问题，本文设计一套适配老人的智能监护系统。该系统以STC12C5A60S2单片机为核心，整合PulseSensor心率传感器、DS18B20温度传感器、GT-U7 GPS模块及蜂鸣器，采用“硬件集成+软件控制”模式，通过单总线、串口通信实现数据传输，无需额外转换模块，简化硬件设计。系统可精准监测老人心率、体温等生理参数，实时输出定位信息，异常时自动触发报警，运行稳定、操作简便。该系统有效弥补传统监护不足，能全方位保障老人安全，且成本可控、实用性强，适配家庭及社区养老场景，可满足老人日常监护需求，具有较高的推广价值与应用前景。

In response to the problems of delayed response in elderly care at home and in the community, inconvenient positioning, inability to call for help in case of sudden illness, and easy getting lost, this paper designs an intelligent monitoring system suitable for the elderly. The system takes the STC12C5A60S2 single-chip microcomputer as the core, integrates the PulseSensor heart rate sensor, DS18B20 temperature sensor, GT-U7 GPS module and buzzer, and adopts the "hardware integration + software control" mode. Data transmission is achieved through single-wire and serial communication without the need for additional conversion modules, simplifying the hardware design. The system can accurately monitor the physiological parameters of the elderly such as heart rate and body temperature, output real-time positioning information, and automatically trigger an alarm in case of abnormality. It operates stably and is easy to operate. This system effectively compensates for the shortcomings of traditional monitoring, can comprehensively ensure the safety of the elderly, and has controllable costs and strong practicality. It is suitable for home and community elderly care scenarios and can meet the daily monitoring needs of the elderly, with high promotion value and application prospects.
