Automatic transportation management systemof vehicles in open pit based on 3PGS and GPS

摘要

The management of mining trucks and other vehicles in the process of transportation is an important issue, in order to prevent from ore stealing and guarantee the obedience of scheduling commands in many open pits. In this paper, a new automatic management and control strategy - "three point guarding system(3PGS)" and GPS truck tracking strategy have been proposed. The objective of these strategies is to prevent stealing ore and monitor vehicles in real time. In 3PGS, three points should be arranged, which consist of weighing point in mining area, passing verification point of entrance and exit in open pit, and weighing point in unloading area. Using weighing sensor, radio frequency identification, automatic barrier control, Ethernet network technologies and systems engineering theory, the trucks and vehicles can be managed and controlled well through to pass three points orderly. Using GPS, the positions of trucks can be monitored in real time in the whole transportation process. Based on 3PGS and GPS, a new automatic transportation management system of vehicles in open pit has been designed and developed. The system has been applied in Sandaozhuang Molybdenum open pit. The application results show that it is an effective solution to prevent from ore-stealing, to manage inlet and outlet automatically and to monitor the trucks in real time in open pit mine.
