摘　　要：设计了基于STM32的智能云听诊控制系统。整个系统采用STM32单片机作为控制核心,通过拾音模块将心肺音信号转换为模拟电信号,再经过滤波放大电路对模拟信号进行滤波和放大;通过功率放大器进行人工听诊,也可以通过微处理器将放大的模拟心肺音信号转化为数字信号,由蓝牙模块传送给手机、计算机等终端设备,再通过手机和计算机将数据上传到云端服务器进行远程云听诊。通过搭建硬件电路,验证了系统设计电路的正确性和可靠性。该系统可将用户端的心肺数据传送至云端,进行智能云端诊断,为远程诊断提供单片机数据。This paper designs an intelligent cloud auscultation control system based on STM32. The whole system uses STM32 microcontroller as the control core, converts the heart and lung sound signal into analog electrical signal through the pickup module;then filters and amplifies the analog signal through the filter amplifying circuit, and conducts manual auscultation through the power amplifier. The amplified analog heart and lung sound signal are converted into digital signal and transmitted to mobile phones, computers and other terminal equipment through the Bluetooth module. The data is uploaded to the cloud server through the mobile phone and computer for remote cloud auscultation. By building the hardware circuit, the correctness and reliability of the circuitis verified. The system can transmit the cardiopulmonary data of the client to the cloud, perform intelligent cloud diagnosis and provide the data for the remote diagnosis.
