Abstract
Despite the positive trend in safety provision of service personnel in solid minerals mining and preparation coal companies continue to invest large amounts of money in order to minimize injuries and death cases among their employees, as well as employees of contractors operating at preparation plants, open-cast and underground mines. One of the main factors leading to the dangerous situations’ emergence at any enterprise is a large number of moving parts of mechanisms (conveyor belts, vibration screens, etc.), presence in a restricted space as well as the need to perform labor duties near technological equipment. The simplest and most effective means of protecting maintenance personnel from moving aggregate parts is the presence of fences around dangerous mechanisms. The integrity of fences is controlled by sensors. However, the sensors often fail because of mechanical damages, impulse overvoltages in the power circuit, and hard operating conditions. At the same time, because of production need, maintenance personnel can remove protective barriers. Thus, it is not uncommon for a situation where, on the one hand, there is no mechanism start automatic blocking, on the other hand, the service personnel carry out their labor duties in close proximity of technological equipment moving parts, which in the end can lead to injuries and even death of people. To prevent non-standard start-up of technological equipment, it is proposed to develop an automatic video surveillance system using computer vision techniques. Such systems in real time receive an image from the production site and by processing the information obtained using a computer vision algorithm that uses local binary patterns, detect the maintenance personnel presence at the production site. When identifying a person on the image received from the camcorder, the system generates a signal about the prohibition of starting (stopping) technological equipment.
