Abstract
The paper discusses the feasibility of implementing a system to prevent personnel from riding a conveyor. This system is based on the data collected by the local positioning system applying the method of distance measurements by the travel time of the ultra-wide band signal. Tests were performed using the SBGPS system produced by Granch Ltd. (Novosibirsk), deployed at the coal mine, for which a site was selected equipped with a belt conveyor and one of the base stations, that supports the tested positioning method. The results demonstrate that the accuracy of this system allows an easy differentiation between the movement of the controlled objects on foot and on top of the conveyor belt. The reaction time of the system is about 5-7 seconds with a stable wireless connection, which requires considering the area of the controlled device relocation as well as possible constraints on deployment of the base stations, i.e. additional requirements for areas with this functionality when deploying the infrastructure.
