Regional positioning method based on BLE-LoRa-GPS

Abstract

The invention discloses a regional positioning method based on BLE-LoRa-GPS. The regional positioning method comprises the following steps of: dividing a positioning region into a first type region and a second type region which are independent of each other; deploying a LoRa wireless transmission module in the second type region, wherein a signal of the LoRa wireless transmission module covers the whole second type region; dividing a special region in the second type region, deploying an ibeacon in the special region, and enabling a signal of the ibeacon to cover the whole special region; installing a second positioning module on a positioning terminal; and judging the region where the positioning terminal is located according to the signal receiving conditions of the second positioning module for the LoRa wireless transmission module and the ibeacon. Regional positioning in an indoor region and an outdoor region is realized by combining different wireless signals.

Description

technical field [0001] The invention relates to the technical field of positioning and navigation, in particular to an area positioning method based on BLE-LoRa-GPS. Background technique [0002] Existing tracking and positioning methods are generally divided into indoor type and outdoor type. Outdoor methods are based on GPS or A-GPS positioning, using 2G / 3G network as backhaul, resulting in high cost, high communication costs, and high power consumption, which cannot be adapted to indoor applications. Indoor methods are usually based on BLE (Bluetooth Low Energy Technology) or accelerometer gyroscopes, and use WiFi networks as the backhaul, resulting in high power consumption and cannot be used in outdoor environments. When using wireless signals to achieve positioning in a large area, since large areas are usually not a single indoor environment or outdoor environment, a single wireless signal alone cannot completely cover all places in the area. In addition, if you need...

Indoor methods, usually based on BLE (Bluetooth Low Energy Technology) or accelerometer gyroscopes, use WiFi networks as the backhaul, resulting in high power consumption and cannot be used in outdoor environments

When using wireless signals to achieve positioning in a large area, since large areas are usually not a single indoor environment or outdoor environment, a single wireless signal alone cannot completely cover all places in the area. In addition, if you need to locate complex special areas, you need to deploy more Multiple base stations for assistance
