This paper presents an OSA patient interactive monitoring system based on the Beidou system. This system allows OSA patients to get timely rescue when they become sleepy outside. Because the Beidou position marker has an interactive function, it can reduce the anxiety of the patient while waiting for the rescue. At the same time, if a friend helps the OSA patients to call the doctor, the friend can also report the patient's condition in time. This system uses the popular IoT framework. At the bottom is the data acquisition layer, which uses wearable sensors to collect vital signs from patients, with a focus on ECG and SpO2 signals. The middle layer is the network layer that transmits the collected physiological signals to the Beidou indicator using the Bluetooth Low Energy (BLE) protocol. The top layer is the application layer, and the application layer uses the mature rescue interactive platform of Beidou. The Beidou system was developed by China itself, the main coverage of the satellite is in Asia, and is equipped with a high-density ground-based augmentation system. Therefore, the Beidou model improves the positioning accuracy and is equipped with a special communication satellite, which increases the short message interaction function. Therefore, patients can report disease progression in time while waiting for a rescue. After our simulation test, the effectiveness of the OSA patient rescue monitoring system based on the Beidou system and the positioning accuracy of OSA patients have been greatly improved. Especially when OSA patients work outdoors, the cell phone base station signal coverage is relatively weak. The satellite signal is well-covered, plus the SMS function of the Beidou indicator. Therefore, the system can be used to provide timely patient progress and provide data support for the medical rescue team to provide a more accurate rescue plan. After a comparative trial, the rescue rate of OSA patients using the detection device of this system was increased by 15 percentage points compared with the rescue rate using only GPS satellite phones.
本文提出了一种基于北斗系统的阻塞性睡眠呼吸暂停（OSA）患者交互监测系统。该系统允许 OSA 患者在室外困倦时及时得到救援。由于北斗位置标记具有交互功能，它可以减少患者在等待救援时的焦虑。同时，如果朋友帮助 OSA 患者呼叫医生，朋友也可以及时报告患者的病情。该系统使用流行的物联网框架。底层是数据采集层，使用可穿戴传感器从患者身上采集生命体征，重点是 ECG 和 SpO2 信号。中间层是网络层，使用蓝牙低能 (BLE) 协议将收集到的生理信号传输到北斗指示器。顶层是应用层，应用层使用成熟的北斗救援交互平台。北斗系统是由中国自主研发的，卫星的主要覆盖范围在亚洲，并配备了高密度的地基增强系统。因此，北斗模型提高了定位精度，并配备了专用通信卫星，增加了短消息交互功能。因此，患者在等待救援的同时，可以及时报告疾病进展。经过我们的模拟测试，基于北斗系统的 OSA 患者救援监测系统的有效性和 OSA 患者的定位精度都得到了很大的提高。特别是当 OSA 患者在户外工作时，手机基站信号覆盖相对较弱。卫星信号覆盖良好，加上北斗指示器的短信功能。因此，该系统可用于及时提供患者的病情进展，并为医疗救援团队提供更准确的救援计划提供数据支持。经过对比试验，使用该系统检测设备的 OSA 患者的救援率比仅使用 GPS 卫星电话的救援率提高了 15 个百分点。
