Downhole worker positioning method based on Wi-Fi signal strength

Abstract

The invention discloses a downhole worker positioning method based on Wi-Fi signal strength. The downhole worker positioning method comprises installing Wi-Fi base stations at intervals of a certain distance in a mine straight line roadway, installing base stations at inflection points and branch points of the roadway, carrying a Wi-Fi wireless network card in a portable device of a mine worker, and enabling the base stations and the network card to form a downhole wireless communication network. The distances between the worker and the two nearest base stations are calculated according to the Wi-Fi signal strength received by the wireless network card, and position information of the worker is obtained according to the proportion of distance. A Wi-Fi wireless network technology is utilized to position the downhole worker in real time, safety guarantee is provided for downhole operation by reasonably arranging the base stations and simplifying positioning algorithms, and possibility is provided for integration with a mine communication system based on Wi-Fi.

Description

technical field [0001] The invention relates to a personnel positioning method, in particular to an underground personnel positioning method based on Wi-Fi signal strength. Background technique [0002] Underground personnel positioning is an important technology to ensure the safety of mine workers and facilitate managers to understand the underground working conditions in real time. [0003] In the past, considering the cost of communication, technologies such as RFID, Zigbee, and PHS systems were mostly used in the positioning of underground personnel in my country. The communication equipment involved in these technologies is relatively low in cost and low in power, but the reliability, accuracy, and anti-interference ability of communication , The diversification of communication forms is greatly restricted. In recent years, wireless communication technology has developed rapidly, and equipment costs have been continuously reduced. Modern management methods have put ...
