Micro inertial navigation-based positioning system and positioning method of routing inspection mobile terminal

Abstract

The invention relates to a micro inertial navigation-based positioning system and a positioning method of a routing inspection mobile terminal, and aims to provide a positioning system and a positioning method which are high in positioning precision. The positioning system comprises a routing inspection handheld terminal and a plurality of Bluetooth beacons, wherein the routing inspection handheld terminal further comprises a micro processor, a three-dimensional acceleration sensor, a three-dimensional electronic compass and an electronic gyroscope; the data output ends of the three-dimensional acceleration sensor, the three-dimensional electronic compass and the electronic gyroscope are respectively connected with the data receiving end of the micro processor; all the Bluetooth beacons are respectively arranged at all routing inspection positions in a petrochemical plant; the data signal output ends of all the Bluetooth beacons are connected with the data signal receiving end of the micro processor; the signal end of the micro processor is connected with the signal receiving end of an upper computer through a communication base station and a 4G network.

Description

technical field [0001] The present invention relates to the technical field of inspection, in particular to a micro-inertial navigation-based positioning system and positioning method for an inspection mobile terminal. Background technique [0002] At present, in the petrochemical field, the petrochemical plant area is mostly multi-layer steel frame structure, and the environment is relatively complicated. It is necessary to use positioning devices to locate the staff during the inspection process of the staff. In the process of industrial on-site inspection, the positioning methods used by traditional staff are limited to wireless positioning methods such as GPS positioning and WIFI positioning. Due to the presence of a large number of steel structure equipment facilities, workshops and pipe corridors and other obstructions on the industrial site, GPS signals and The WIFI signal is blocked or refracted, which seriously affects the positioning accuracy and cannot accurately ...
