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.

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. [ABSTRACT FROM AUTHOR]
