Abstract

The invention relates to the technical field of wireless positioning, and provides a mine underground positioning system based on a wireless sensor network. The mine underground positioning system comprises a positioning system server, a bus, positioning base stations and mobile wireless positioning machines, wherein the mobile wireless positioning machines are wirelessly connected with the positioning base stations; a plurality of positioning base stations construct a positioning base station network; the positioning base station network is connected with the bus; the bus is connected with the positioning system server through a transmission interface; and according to a positioning algorithm of the mobile wireless positioning machines, a RSSI (Received Signal Strength Indicator) ranging environment parameter is corrected through a least square method. The mine underground positioning system has the beneficial effects that the RSSI ranging environment parameter is corrected through the least square method, so that the influences of various interference on measurement data are eliminated; the ranging accuracy is increased; and the defect of presence of dead zones in a conventional network camera monitoring system is overcome effectively. The mine underground positioning system has the advantages of high positioning node integration level, high positioning accuracy, low power consumption, short delay, high network capacity, low cost and suitability for popularization and application.

Description

technical field [0001] The invention relates to the technical field of wireless positioning, in particular to a mine underground positioning system based on a wireless sensor network. Background technique [0002] With the transformation and leapfrog development of my country's economy, higher requirements are put forward for safety production, especially the safety management of workers in high-risk environments has become an urgent task. The research and development of underground positioning system is gradually becoming an urgent requirement of the times. [0003] In the underground positioning process based on the wireless sensor network, the geographical location of the event is often the key information that needs to be mastered first. If the location information of the event cannot be obtained in time, the information obtained during the monitoring is often meaningless , and people cannot deal with it accordingly. It can be seen that positioning technology plays a vi...
