Abstract: For low supervision efficiency of coal storage yard working, a loading process tracing and feedback system of coal storage yard based on GPS was designed, and design scheme of positioning terminal of loader shipment based on STM32F103VET6 was expounded. In the system, electronic fence is set in coal storage area by use of GPS technology, thus multi coal type storage areas are divided according to distribution of coal types. GPS positioning information of the loaders is uploaded to server real-timely through GPRS network by the positioning terminal, so as to record, analyze and manage loading process data real-timely. The system can be connected to existing coal mine weighing system and weighing data can be forwarded to the positioning terminal real-timely for improving loading efficiency.
