基于蓝牙技术的物品寻找器设计

摘要

基于蓝牙技术的低成本、低功耗、高速度通信的优势，以及智能手机的普及，针对小型物品易于放置在难于发现的位置，寻找较为困难的问题，设计了一款物品寻找器。采用JAVA语言编写智能手机端App，通过蓝牙与绑在物品上的寻找器进行通讯，发出声音和亮光，引导人们寻找到物品。经过实际测试，该物品寻找器与智能手机App运行稳定可靠，最大寻找距离达25米，并且该物品寻找器可进一步扩展其功能用于各类无线短距离控制系统。%An item finder is designed for problem that small objectswhich are liable to be placed in the location difficult to find, based on advantages of bluetooth technology as low cost, low power consumption, high speed communication, as well as the proliferation of smart phones.The smart phone App is written with JAVA language,which can communicate with the finder tied to the item through the Bluetooth,and sound and light to guidepeople to search the item.The actual test shows that the finder and smartphone App are stable and reliable operation,and the maximum search distance can up to25 m.
