The main piece of transport equipment used in coal mines is the steel cord conveyer belt, which encounters problems in start and stop impact, deviation and belt tear fault integrated protection, intelligent identification of defects, and key components fault diagnosis for the transmission system. This paper thus studies certain key technologies of the steel cord conveyer belt, such as soft start control and energy saving operations, integrated protection and fault diagnosis for the transmission system, defect testing, and intelligent recognition methods. An intelligent monitoring system of the steel cord conveyer belt was put forward, and an intelligent monitoring experiment platform was built. This system can achieve frequency conversion control, weak magnetic defect testing, integrated protection for running faults, and key components fault diagnosis for the transmission system. It solves the problem of information silos between modules and achieves comprehensive intelligent protection of the steel cord conveyor belt. The intelligent monitoring system is significant for ensuring the safety of the conveyer belt and thus the safe and efficient production of coal mines.
