Design And Implementation Of SOS System Based On Android Smartphones

Along with the rapid development of the 4G era, more and more people are using smart phones, smart phones have been more than just a fun toy, but has become a people’s daily lives channels provide a variety of services and tools. Now there is a growing emphasis on their security awareness, particularly vulnerable groups such as the elderly and children, received widespread concern in the community. Along with the urgent needs of the social development, based on a variety of mobile access to the rapid development on smart phones, location-based emergency services technology became the focus of attention.Research focus areas are basically smart phones based on the Android platform, the android platform, similar surveys flowers occupy more than 75% market share of smart, advantages Android platform is on the map with the refinement of control functions and information display multi-faceted. Android platform also has a good open expansion, which is why most software and hardware vendors chosen because Andrews. In this paper, Android platform, developed an SOS(Send-Our-Succour, commonly known as speed to the rescue) rescue system, which with intelligent terminal communications and positioning technology, and ultimately a credible emergency phone services. In this paper, the specific work as follows:1) study the advantages and disadvantages of intelligent terminals currently existing SOS system, focusing on analysis already exists practicality and stability of the system proposed in this paper optimization program on the basis of full research program will use two types of information collection: locating information plus live on information, and increase the usefulness of the system; uses method repeatedly sending push data to improve the stability of the system.2) to study and analyze the structure and characteristics of the Android platform, focusing on the next step Android platform application development, analysis and research papers on the functional needs.3) analysis of component services, and under the framework of Andrews presents a component-based SOS alarm system, the system will be sent by means of deployment and interactive component model, while using message distribution cooperative mechanisms, components corresponding command to complete the operation after the broadcast news to other components, the same components will be processed after the received broadcast message, the message is forwarded to reduce overall redundancy and improve the efficiency of message transmission and reception.4) With a hierarchical model for SOS system to be divided, from bottom to top in turn represented as data collection layer, data layer, sending back layer, presentation layer, while the layers of components listed in the structural relationship and interaction models. System ultimately features include: to locate and capture the Naxi, multi-target binding distress, distress scene in various forms(video, images, voice, etc.) information collection, help edit and send messages automatically, location tracking and other functions.
