| Services for the aged industry as an emerging industry has been more and more national attention, so the services for the elderly industry information and exploring new service mode service development is of great significance to the old. The elderly services as the main research contents, this paper designed a senior services system based on the Android platform, and completed the detailed design and development of the specific function module. The main research contents are as follows:(1) Through the logistics system, combining medical, housekeeping, life and other service system together, to form the new services for the elderly intelligence solutions. And complete the elderly service functional design, in consideration of the practical needs of the elderly.(2) Design fall detection model based on Android platform. Through a detailed analysis of the difference between daily life events and fall events fall detection, adopt falling detection by module, so that the model has the flexibility to expand and improve. In addition, adding static detection module and gesture detection module, effectively reduce the under report rate and false alarm rate. The fall algorithm of fall detection is low computational complexity, high efficiency, and the actual test proved that the model has a strong practical value.(3) Other major module design and implementation of the elderly service system. Complete the communication module design, by choosing socket communication program, detailed design of signaling interaction and communication messages; complete database module design, by dividing database functions, detailed design of the database table; using Baidu map locating SDK completes terminal location, maps, route navigation, emergency rescue and other functions. (4) Testing and verifying senior services system. By building a test environment, and designing test scenarios, testing and verifying function modules. Experimental results show that the elderly fall detection model service system has a low under report rate and false alarm rate. Terminal function modules run normally, and the system has good feasibility and reliability... |
