A recently granted patent (Publication Number: US11885204B2) introduces a system designed to enhance safety on drilling rigs by mitigating accidents. The system includes a network of cameras strategically placed to capture real-time images of various zones on the rig floor. These images are then sent to a master control computer system that processes and analyzes them to detect the presence of rig hands. By utilizing a map of unsafe zones around items on the rig, the system can assess if a rig hand is within a dangerous area and subsequently allow or disallow the operation of certain items in that zone. Additionally, the system incorporates cameras at entrance points to monitor the movement of rig hands, enabling the computer system to track their entry and exit in real-time.
Furthermore, the patent claims highlight the advanced capabilities of the system, such as the ability to identify specific items on the rig floor and locate them on the map of unsafe zones. The master control computer system utilizes algorithms to scan images for stored item images in memory, allowing for efficient analysis and decision-making. Moreover, the system includes default unsafe zones for each item, ensuring a proactive approach to safety management. Additionally, the computer system is equipped with algorithms designed to identify specific features of rig hands, further enhancing the system's ability to monitor and control access to unsafe zones effectively.
