Abstract: For problems of huge construction cost and maintenance existed in a transportation monitoring system of explosion-proof rubber-tyred vehicle based on RFID technology, a monitoring system of explosion-proof rubber-tyred vehicle based on 3G communication network used in mine was proposed, and overall structure of the system and design scheme of communication terminal were introduced. The system can real-timely monitor running status of explosion-proof rubber-tyred vehicle through existing 3G communication network used in mine, which only need equip a communication terminal in explosion-proof rubber-tyred vehicle. The test rsults verify reliability and stability of the system. The system has run for 6 months without any fault in a coal mine.
