Embodiment Construction

[0048] When using GPS to obtain node location information, it is necessary to install a GPS module on the node, which is costly; and needs to receive signals from at least 3 or more GPS satellites, but GPS signals cannot penetrate indoors, so GPS cannot be used indoors.

[0049] In order to solve the above problems, an embodiment of the present invention provides a positioning data collection method, which collects and reports the ranging data required for positioning through each tag node in the network. The network system used by the embodiment of the present invention is as figure 1 As shown, at least one label node 101 , at least one beacon node 102 and information aggregation node (Sink) 103 are included. Among them, the label node 101 is specifically a mobile terminal, the beacon node 102 is a base station, and the information aggregation node 103 is also a base station. However, in general, in a wireless sensor network, there is only one information aggregation node, wh...

Abstract

The invention discloses a method, device and system for acquiring positioning data, and relates to the field of mobile communication, and the method, device and system provided by the invention are used for solving the problem of high cost in the event that the position information data of a node is acquired by a GPS (global positioning system). The method comprises: a label node determines a positioning time slot used by the label node according to a preset node number and time slot interval; the label node measures the distance of a beacon node at the positioning time slot so as to obtain distance-measuring data; and the label node uploads the distance-measuring data to an information convergence node. The technical scheme provided by the invention is applicable to a wireless sensor network (WSN).

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a positioning data collection method, device and system. Background technique [0002] With the rapid development of micro-electromechanical systems, system-on-chip, wireless communication and low-power embedded technology, wireless sensor networks have been bred, and have brought information perception with its low power consumption, low cost, distributed and self-organizing characteristics. of a change. The wireless sensor network is composed of a large number of cheap micro sensor nodes deployed in the monitoring area, and forms a multi-hop self-organizing network through wireless communication. [0003] Wireless sensor network is a brand-new information acquisition platform, which can monitor and collect information of various detection objects in the network distribution area in real time, and send this information to the gateway node to realize complex target de...
