摘　　要：为提高防疫抗疫水平,加强对隔离状态下的病毒性肺炎潜在患者的观察监护,提出一种基于DA14699蓝牙低功耗芯片的医疗用智能监护项圈。设计方案以DA14699芯片为主控制器,依靠其无线多核的高效处理能力,对潜在病患的体温、咳嗽及定位信息进行记录与分析。利用LIS3DH三轴加速度传感器对咳嗽症状进行判断,借助MLX90640红外传感器对体温保持连续测量,采用L218四频GSM/GPRS定位模块完成人员的快速精准定位,从而实现对潜在病患居家隔离措施执行情况的全面监督。DA14699芯片支持蓝牙BLE5.1协议,防疫人员可远距离对智能项圈内记录的数据进行传输读取,并在智能手持终端上直观展示。这有效避免了近距离接触带来的感染风险。经实际测试,该项圈关键参数监护功能高效可靠,具有较高的推广应用价值。In order to improve the level of epidemic prevention and control,and strengthen the observation and monitoring of potential patients with viral pneumonia in isolated state,a medical intelligent monitoring collar based on DA14699 Bluetooth low-power chip was proposed.DA14699 chip is used as the main controller in the design scheme,and the temperature,cough and location information of potential patients are recorded and analyzed by its high-efficiency wireless multi-core processing ability.The LIS3DH three-axis acceleration sensor is used to judge the cough symptoms.The MLX90640 infrared sensor is used to continuously measure the body temperature.The L218 four frequency GSM/GPRS positioning module is used to complete the rapid and accurate positioning of personnel,so as to realize the comprehensive supervision of the implementation of home isolation measures.DA14699 chip supports Bluetooth BLE5.1 protocol.Epidemic prevention personnel can transmit and read the data recorded in the smart collar from a long distance,and display it directly on the intelligent Bluetooth handheld terminal,effectively avoid the risk of infection caused by close contact.Through the actual test,the monitoring function of the key parameters of the collar is reliable and has high application value.
