摘　　要：在传统钢芯输送带漏磁检测的基础上,采用空间磁感应强度ωB T的Z轴分量ωB z监测新方法,也即利用钢绳芯的每组接头、断口的漏磁对应一对磁偶极子的N、S极,通过监测磁偶极子N、S极的极值点信号,来实现对输送带的损伤监测,提高了数据的实时处理能力。另外,通过对相关2种类型传感器分析比较,得出了更为合理的霍尔元件作为监测元件。实验结果表明,空间磁感应强度ωB T的Z轴分量ωB z检测方法具有可靠性高、实时性好、通用性强、安装使用方便等优点。Based on the conventional magnetic flux leakage test of steel-cord belt, a new method for monitoring the Z-component of the space magnetic field intensityis proposed, in order to monitor the belt status by monitoring the signal at extreme points of N and S poles of magnetic dipole pole, and a more reasonable hall sensor is selected as the monitoring sensor based on the analysis of the theory of two kinds of sensors. This method will enhance the ability of real-time dealing with data. Experiments show that the new method is more feasible, quicker, and more convenient to use.
