This study presents a new ubiquitous emergency medical service system (UEMS) that consists of a ubiquitous tele-diagnosis interface and a traffic guiding subsystem. The UEMS addresses unresolved issues of emergency medical services by managing the sensor wires for eliminating inconvenience for both patients and paramedics in an ambulance, providing ubiquitous accessibility of patients' biosignals in remote areas where the ambulance cannot arrive directly, and offering availability of real-time traffic information which can make the ambulance reach the destination within the shortest time. In the proposed system, patient's biosignals and real-time video, acquired by wireless biosensors and a webcam, can be simultaneously transmitted to an emergency room for pre-hospital treatment via WiMax/3.5 G networks. Performances of WiMax and 3.5 G, in terms of initialization time, data rate, and average end-to-end delay are evaluated and compared. A driver can choose the route of the shortest time among the suggested routes by Google Maps after inspecting the current traffic conditions based on real-time CCTV camera streams and traffic information. The destination address can be inputted vocally for easiness and safety in driving. A series of field test results validates the feasibility of the proposed system for application in real-life scenarios.
本研究提出了一种新的普及型紧急医疗服务系统（UEMS），该系统由普及型远程诊断接口和交通引导子系统组成。UEMS 通过管理用于消除救护车中患者和护理人员不便的传感器线，为无法直接到达的远程地区的患者生物信号提供普及型可及性，并提供实时交通信息可用性，从而解决了紧急医疗服务中存在的未解决问题，使救护车能够在最短的时间内到达目的地。在提出的系统中，通过无线生物传感器和网络摄像头获取的患者生物信号和实时视频可以通过 WiMax/3.5G 网络同时传输到急诊室进行院前治疗。评估并比较了 WiMax 和 3.5G 在初始化时间、数据速率和平均端到端延迟方面的性能。司机可以根据实时闭路电视摄像机流和交通信息检查当前交通状况后，从谷歌地图建议的路线中选择最短时间的路线。目的地地址可以通过语音输入，以便在驾驶时更加轻松和安全。一系列现场测试结果验证了该系统在实际场景中应用的可行性。
