The Software Design And Application-Research Of New Home Intelligent Terminal

With the fast development of information technology and network, the intelligent information service has become an important characteristic of information technology industry. As an emerging information equipment, the intelligent terminal products are becoming more and more important to the intelligent home life.By analyzing the existing home intelligent terminal, this thesis designs a new-type terminal based on Android operating system and does some research on its application in the community security. The design of the home intelligent terminal includes three parts, that is, the overall design of terminal, the design of security guard and application software. The application-research is mainly to complete the coverage in the simulation area, the recognition and localization of harmful acoustic signals.Firstly, according to the investigation of home intelligent terminal at home and abroad, this thesis chooses the Cortex-A9as the CPU of the terminal chooses M3that integrated with Mali-400GPU as the core processing unit and finishes the design of auxiliary circuit board. The terminal runs on Google’s Android4.0operating system, and makes the system software tailored and customized to fit the requirement of smart home. The desktop system is also redesigned to make it easier to operate and to enhance the user experience.Secondly, in order to promote the performance and security of the home intelligent terminal, this thesis designs the security guard that mainly includes software management, antivirus, traffic statistics, system ninja, process management, app lock, etc. The security guard software also can detect, download and update the new version automatically.Thirdly, the design of software focuses on the demand of families. In this thesis, four software, including personal finance, the record of household refrigerator, RSS reader, maintenance and upgrading, are designed to meet the users’demand on property, household, access to information and terminal maintenance. So the terminal with these functions can make it more appropriate to the users’ life.At the end of this thesis, it simulates the applied scenario by using the MATLAB. We firstly simulate the area in100*100*100three-dimensional space as the virtual community and then optimize the coverage by using the fish swarm algorithm. Further, we get the parameters and the location of the harmful acoustic signals by using the home intelligent terminals which are simulated in the virtual community. The whole simulation system discusses a new scenario for the home intelligent terminal in the future and it can provide theoretical support for the application which makes it with more practical significance.
