DEVELOPMENT OF AN INFORMATION TECHNOLOGY ALGORITHM FOR THE INTERNAL LOCALIZATION OF IMU BUILDINGS IN NEGIZIN FOR A CONSTRUCTION COMPANY

Abstract

Localization and tracking of resources at construction sites is an emerging industry where the location of materials, labor, and equipment is used to assess performance, assess project progress, and/or improve safety at the construction site. GPS is widely used to monitor outdoor construction work. However, GPS is not suitable for use, especially within tunnels or buildings, due to insufficient signal coverage. Several studies have been conducted on localization within buildings, but such developments are largely due to the extensive infrastructure of external communication networks. These developments are also subject to electromagnetic interference on noisy construction sites. This article presents an in-building insulation system using a microcontroller equipped with an inertial measurement unit (IMU). The IMU contains a set of sensors: accelerometer, gyroscope and magnetometer. The microcontroller uses a direct cosine Matrix algorithm to combine sensor data and calculate non-gravitational acceleration using the equations of motion of nine degrees of freedom. The current position is calculated based on the measured acceleration and course values, which take into account the increase in the error in the speed assessment using the speed integration algorithm. The results of the experiments show the relative efficiency of the developed system, which can work independently of any external means and visibility conditions.
