Problems solved by technology

[0004] Studies have shown that in order to improve the accuracy of positioning algorithms based on RSSI values, the common method is to divide the geographical area of ​​positioning into as many positioning areas as possible, and increase the number of RSSI value collection in each positioning area. The precise positioning of underground personnel is a coal mine The basic requirements of security monitoring, so the establishment of fingerprint information database requires a lot of work

Abstract

The invention discloses a method for rapid fingerprint generation of an underground coal mine worker positioning fingerprint database. The method comprises the following steps that wireless APs of all channels of an underground coal mine have the safe transmitting power and are installed on the corresponding positions of the channels; each channel of the underground coal mine is divided into a plurality of positioning zones, the decline of wireless signals in each positioning zone pair is analyzed, and the positioning zones with the similar decline are classified into a similar class alpha i (i=1,2...,i); fingerprint information beta i is collected from one positioning zone of the similar class alpha i; the fingerprint information beta i is made to serve as an establishing base of fingerprint information of other positioning zones in the similar classes alpha i; according to the method for rapidly generating the fingerprints of the fingerprint database for positioning underground coal mine workers, only the fingerprint information of one positioning zone in one similar class needs to be collected, then the fingerprint information of other positioning zones in the same similar class can be obtained, and therefore the workload of fingerprint collection of the channels of the underground coal mine is greatly reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of positioning, in particular to a method for rapidly generating fingerprints of a personnel positioning fingerprint database in a coal mine underground roadway. 【Background technique】 [0002] With the rapid development of wireless communication technology, wireless positioning technology is also developing rapidly. The location service based on wireless sensor network plays an increasingly important role in people's work and life, which accelerates the development of wireless sensor network location, and wireless sensor network can be used in target location. One of the main goals of wireless sensor networks in the application of coal mine monitoring is to point out the location of the events it monitors. Therefore, when monitoring the environment, personnel, etc., it is important to be able to know the location of the emergency in time. [0003] Different from the ground environment, the coal mine und...
