针对人口老龄化加剧引发的老年护理方面难题，采用STM32F103C8T6主控芯片，构建了智能护理床系统，该系统集阻抗式液体传感器、物联网通信、语音交互等多模态控制技术于一体，通过阻抗式液体传感器（HL-83）实时监测老年患者失禁的状态，若检测值超过了阈值，马上触发蜂鸣器报警，可迅速给老年患者更换床单。利用SU-03T语音模块、独立按键以及云端控制来实现三通道舵机控制，另外借助ESP8266 Wi-Fi模块接入阿里云物联网平台，实现APP远程监查，实验结果说明，该系统反应时间低于200ms，传感器检测的精准程度为97.3%，证实该智能护理床系统具有临床应用价值，合理解决了老年护理中的部分实际矛盾。

In response to the difficulties in elderly care caused by the intensification of population aging, an intelligent nursing bed system has been constructed using the STM32F103C8T6 main control chip. This system integrates multi-modal control technologies such as a rain sensor, Internet of Things(IoT) communication, and voice interaction. The HL-83 rain sensor is used to monitor the incontinence status of elderly patients in real time. When the detected value exceeds the threshold, the buzzer will be triggered to alarm immediately, enabling prompt replacement of the bed sheets for elderly patients. The SU-03T voice module, independent buttons, and cloud control are utilized to achieve three-channel servo control. Additionally, the ESP8266 WiFi module is employed to access the Alibaba Cloud IoT platform, enabling remote monitoring via an APP. Experimental results indicate that the response time of this system is less than 200 ms, and the precision of the sensor detection is 97.3%. It is verified that this intelligent nursing bed system has clinical application value and reasonably resolves some practical contradictions in elderly care.
