Abstract

The invention provides indoor positioning equipment and method. The indoor positioning equipment comprises a microcontroller, a GPS (global positioning system) positioning device, an accelerometer, a barometer, a gyroscope and a digital compass; the microcontroller is connected with the GPS positioning device, the accelerometer, the barometer, the gyroscope and the digital compass. For space lack of GPS signals, a movement track of a carrier can be acquired efficiently and accurately, and the carrier is positioned accurately.

Description

technical field [0001] The invention belongs to the technical field of indoor positioning, and in particular relates to an indoor positioning device and method. Background technique [0002] Existing communication network test terminals mainly determine the movement trajectory of the test terminal through GPS when performing outdoor road DT tests; while performing indoor test projects, or the test terminal is tested on high-speed vehicles such as high-speed rail or encounters tunnels When the building is blocked, since there is no GPS signal indoors or in the high-speed rail, it is often to rely on the tester to manually record the test location to simulate the movement path of the test terminal, so as to realize the navigation and positioning of the test terminal. Specifically, the test Every time the person moves a certain distance, a "point" is marked on the plan, and then the points are connected with lines to form the moving track of the test terminal. It can be seen t...
