摘要
钢绳芯带式输送机具有连续输送能力强、运行效率高、易于实现自动控制等诸多优点而广泛用于矿山、冶金等国民经济部门作为散状物料输送的重要手段。但在其运行过程中,常发生胶带的纵向撕裂,本文针对现有诸多类型带式输送机胶带纵向撕裂检测系统稳定性差、使用寿命短等缺点,深入研究了电磁感应式检测器的电磁感应原理和检测系统的电路,对整个检测系统进行了简单设计,对胶带纵向撕裂进行检测。通过对胶带中的线圈进行不间断的监测,系统能够在胶带发生纵向撕裂时,使输送机停机并发出报警信号,从而大大减少事故的损失。本系统通过对物理变化的检测转变为数字信号的检测,大大提高了整个系统的稳定性和准确性,同时结合单片机使检测更加简单,提高了操作人员的工作效率。

Abstract
The steel cable core belt type conveyer has the ability of continuous strong transport capability, the operating efficiency high, easy to realize the automatic control. So it is widely used in mining, metallurgy and other bulk materials sector as the national economy an important means of transportation. But in the course of its operation,it often has the longitudinal article is in view of many types of belt conveyor belt longitudinal tear monitoring system stability poor, service life short and other ings,in-depth study of the ic induction-detector principle of ic induction and detection system circuit, giving a simple design of the entire monitoring system, monitoring the tape longitudinal the adhesive tape has the longitudinal tearing accident, The system can make the conveyer engine off promptly and sends out the alarm to reduce accident's loss system through transforms of physical changes monitor into the digital signal monitor, greatly improving the overall system stability, at the same time with SCM to make monitor simpler, raise operators' working efficiency.
