| Summary: | 碩士 === 國立交通大學 === 資訊工程系 === 89 === The call-for-help and locational positioning system provides a chance to ask someone a favor for victims in an emergency, and also provides the victim’s location for a rescue department to save the sufferers. The wireless communication is essential to our daily lives due to the well developed and popular wireless communication technology. The wireless communication not only brings us conveniently information retrieval and message exchange but also important lifesaving equipments. How to take the victim’s location, and how to increase the rescue efficiency, are the most popular topics in any discussions related to the helping and position resolution systems.
In this paper, we proposed a distributed call-for-help and locational positioning system, which combined the intelligent wireless entrance control system. With the distributed call-for-help and locational positioning system, it provided an interface, which was simple and easy to use for victims in urgent. And it also supplied emergency services with the precise location information and contact of victims to improve the rescue efficiency. So the victims could avoid damaging their life and wealth.
