项目摘要

VHF analog communications and NTT DoCoMo's mobile communication system are used on ambulance but they suffer from the following problems; 1) narrow band width, 2) multipath, 3) shadowing, 4) limited coverage Under the present wireless communication environment on the ground, we cannot provide a suitable medical control for EMT and cannot avoid troublesome problems during transportation on ambulance. For example, miss insertion of endotracheal tube into esophagus, even well-trained EMT performed 85% in VA. For this reason, we have started to study on possibility of nation wide emergency communications system with high inclined elliptical orbiter aiming to support high data transmission from ambulance. There items are investigated 1. Receiving power at urban area in Japan, beacon from HEO ; COMETS satellite 2. Visibility Measuring with 360 degree of optical camera at urban area in Japan 3. Development quadrant detector with microwave to track target satellite 4. Investigation on frequency limit transponder 5. Comparison between IMT-2000 and HEO 6. Comparison between medical cost of acute myocardial infarction and launching cost of HEO 7. Denoise of ECG with DSP technologyThe satellite communications system with High Elliptical Orbiter might be much more cost effective than IMT-2000 for 4800 ambulances. In the future, data will be sent in real time from land mobile unit, which enable monitoring patient conditions while in transit; providing detailed digital moving images such as light reflex images, injured site, vocal cord image during endotracheal tube insertion, 12 ECG with cardio echography, saturation levels, etc. These transmissions might help patients.

VHF模拟通信和NTT DoCoMo的移动的通信系统被用于救护车上，但是它们遭受以下问题：1）窄带宽，2）多径，3）阴影，4）有限的覆盖范围在目前的地面无线通信环境下，我们不能为EMT提供合适的医疗控制，并且不能避免在救护车上运输期间的麻烦问题。例如，气管内导管插入食管失误，即使训练有素的EMT在VA中也有85%。为此，我们已经开始研究全国范围的紧急通信系统的可能性与高倾斜的椭圆轨道器，旨在支持高数据传输的救护车。调查的项目有1.在日本城市地区接收电力，来自HEO的信标;彗星2号卫星。在日本城市地区用360度光学相机测量能见度3.研制微波四象限探测器跟踪目标卫星4号。频率限制应答器的研究5. IMT-2000和HEO 6之间的比较。急性心肌梗死医疗费用与HEO 7发射费用的比较。采用DSP技术的心电图去噪高椭圆轨道卫星通信系统在4800辆救护车上的应用可能比IMT-2000更具成本效益。未来，数据将从陆地移动的单元以真实的时间发送，这使得能够在运输过程中监测患者状况;提供详细的数字移动图像，例如光反射图像、受伤部位、气管内导管插入期间的声带图像、12心电图和心脏回波描记术、饱和度等。这些传输可能会帮助患者。
