| In the coal mine production process, as main source of traction power transport, thesafety and efficiency of Mining Vehicle is very important. It is necessary to develop a MiningVehicle Monitoring and Positioning System, which needs integration of techniques fromdifferent disciplines, such as horticulture, automation, computer, etc., to achieve safe andefficient mine production.In this dissertation, based on a function requirement analysis for the Mining VehicleMonitoring and Positioning System, a set of important functions and technical parameters ofthe Mining Vehicle Monitoring and Positioning System is defined and summarized, includingthe hardware and software aspects. Reliability, flexibility, operability and cost of a MiningVehicle Monitoring and Positioning System should be primary design targets. This systemdesign approach for such a detailed discussion, proposed mine locomotive control systemdesign principles: under the premise of the national standards on mine safety, matureindustrial modules is preferred to be a systems integration, to ensure reliable, and thenoptimize the system to achieve low cost.A necessary condition of mine locomotive efficient dispatching is positioning thelocomotives, this paper combines the RFID absolute positioning technology and relativepositioning method by measuring displacement to achieve precise positioning of minelocomotives. Meanwhile, real-time positioning information is uploaded through undergroundWiFi network, displayed on the screen of both the central dispatching room and thelocomotive, which provide reference for locomotive dispatching. Besides, underground voicecommunications, Drowsy Driver Detection, Pedestrian detection and power supply and otheraspects of the design is the content of this research.Finally to validate the above research, the whole system is tested in the a cola mine.Right warning of security risks, and production efficiency risen proved that this system hadreached its anticipated design object. |
