Layered positioning system and layered positioning method

Abstract

The invention relates to a layered positioning system and a layered positioning method, which adopt an information server, and a master device and a slave device which are connected with the information server. The information server comprises a position information database, a tracking module and a warning module; the master device comprises a data processing unit, and a positioning module and amaster ZigBee module which are connected with the data processing unit; the slave device comprises a slave ZigBee module and a sensor module which is connected with the slave ZigBee module; and the information server, the master device and the slave device form a sensor network through the ZigBee modules to determine the position and the moving state of an object. The layered positioning system and the layered positioning method are difficult to be disturbed, have the advantages of good reliability, low cost and easy regulation for scales, are suitable for large-scale use; moreover, the layered positioning system and the layered positioning method do not need a new conductor wire, and have lower power consumption and low running cost; and the positioning system can be freely moved. 本发明涉及一种分层定位系统和方法，采用信息服务器和与之相连接的 主设备、从设备，信息服务器包括位置信息数据库、追踪模块和报警模块， 主设备包括数据处理单元和与数据处理单元相连接的定位模块和主ZigBee 模块，从设备包括从ZigBee模块、与从ZigBee模块相连接的传感器模块， 信息服务器、主设备、从设备通过ZigBee模块形成传感器网络以测定物体的 位置和移动状态。本发明的分层定位系统和方法，不易被干扰、可靠性好、 成本低、规模易调整、适宜大规模使用，此外不需要新的导线，且具有较低 的功率消耗，低廉的运行成本，还可自由移动本定位系统。
