高精度低功耗室内外无缝定位的实验室物品追踪管理系统设计
|
摘要
针对当前生物医学实验室平台物品安全管理困难的问题,设计了一种高精度低功耗实验室物品室内外定位追踪系统。该系统采用蓝牙进行室内定位,GPS结合北斗的方法实现室外定位,并利用加速度传感器检测物品的位移来控制系统的功耗,然后通过GPRS无线通信模块将定位数据发送到数据库中,在数据库中完成定位运算并将数据进行保存,用户利用手机APP访问数据库实时查看物品位置信息。通过实验测试,证明了本系统可以有效地对实验室物品进行定位追踪。
Aiming at the problem of safety management of the biomedical laboratory platform,a high-precision and low power indoor and outdoor location tracking system for laboratory items was designed in this paper. The system uses Bluetooth indoor positioning,Global Positioning System and Beidou system to achieve outdoor positioning,and uses acceleration sensors to detect the displacement of items to control system power consumption,and then through the GPRS wireless communication module sends data to the database,completes positioning operation in the database and saves the data. Users can use APP to access the database,check the items location information in real time. Through experimental tests,it is proved that this system can effectively locate and track the laboratory items.
