| Summary: | 碩士 === 國立臺北科技大學 === 資訊工程系研究所 === 99 === Global Positioning System, GPS, is a system combining with the satellite navigation and wireless network technology to provide the accurate positioning, speed and time to the users. Geographic Information Systems, GIS, is an information operation system integrating related geographic information and designed on the basis of completed geographic database. It has the functions as below: data catch, data edit, data update, data saving, data search, data analysis, data showing, etc.
Because GPS and GIS are used popularly today, the navigation and the positioning become more accurate and more convenient. Besides, the mobile communication is also developed quickly now, so many new services based on the location are to integrate the geographic information and provide to the users.
This thesis designs a system combining satellite navigation and mobile communication technology. It provides a driver the positions and forward directions of the emergency vehicles such as a ambulance or a fire engine and also provides voice warning and avoiding guiding to let the emergency vehicle can arrive at the destination quickly and safely. This system use GPS to locate the position of the emergency vehicle and transmit its position to a server. Then the server will publish the position information of the emergency vehicles to all registered clients. When the general driver’s smart phone receives this information, it calculates the real position, distance and direction of the emergency vehicles by the algorithm and provides the proper voice warning and the avoiding guiding.
In order to make the system easier being used, the software for both general and emergency vehicles are designed under Android platform. It can be downloaded and installed quickly on Android platform of the driver’s smart phone. The driver can login as a client and use all functions through GPS and 3G wireless mobile communication networks.
