【摘要】：钢丝绳具有很强的过载能力、抗拉强度以及抗疲劳强度等特点,在煤矿生产作业中得到了广泛的利用。在矿井往井下运输人员的架空人车系统中,钢丝绳作为架空人车运输的承载体,它的安全性及使用状态关乎工人生命,对于其损伤的实时在线无损检测显得至关重要。由于钢丝绳不间断地运行,损伤部位被检测到后将随着系统的运行远离钢丝绳检测装置。所以对于损伤的定位、实时跟踪与状态显示也是检测系统一项重要功能指标。研究一种实时高效并能跟踪状态的钢丝绳检测系统,可以为矿井工作人员对架空人车钢丝绳的状态监控与维护更换提供重要的数据支持与参考意见。本论文采纳了当前钢丝绳检测理论的优秀研究成果,基于强励磁状态下的漏磁原理设计了架空人车钢丝绳无损在线监控系统。根据矿井现场架空人车运行系统中钢丝绳的损伤特征以及运行特征,将钢丝绳检测系统分为两大部分设计：一部分是主检测系统,利用磁偶极子理论对钢丝绳损伤漏磁场特征进行建模并仿真,提出以钕铁硼材料的永磁体为励磁方式、以霍尔元件为核心的漏磁检测装置方案,并对软硬件进行设计介绍；另一部分是基于RFID技术的损伤定位跟踪模块,根据现场条件,选定基于IS015693协议的13.56MHz射频读写系统对定位模块进行构建,详述定位原理并利用软件绘制钢丝绳运行状态图,实现损伤跟踪显示。煤矿现场存在复杂的电磁环境,会对钢丝绳检测设备的检测信号产生非常不利的干扰及噪声。文章对煤矿电磁环境进行分析,提出存在的各类电磁干扰,并针对性地对检测系统进行EMC电磁兼容设计。
[Abstract]:Wire rope has been widely used in coal mine because of its strong overload capacity, tensile strength and fatigue strength. In the overhead man-vehicle system, the safety and use state of steel wire rope is vital to workers' lives, and it is very important to the real-time on-line nondestructive detection of the damage. Because of the continuous operation of the steel wire rope, the damaged part will be far away from the wire rope detection device after it is detected. Therefore, for damage location, real-time tracking and state display is also an important function of the detection system. This paper studies a real time and high efficiency steel wire rope detection system which can provide important data support and reference for mine workers to monitor and maintain the status of overhead passenger car wire rope. Based on the principle of magnetic flux leakage under strong excitation, a nondestructive on-line monitoring system for steel wire rope of overhead passenger car is designed in this paper, which is based on the excellent research results of the current theory of wire rope detection. According to the damage characteristics and operation characteristics of steel wire rope in the running system of overhead man car in mine field, the detection system of wire rope is divided into two parts: one is the main detection system, the other is the main detection system. Using magnetic dipole theory to model and simulate the magnetic field leakage characteristics of wire rope damage, a scheme of magnetic leakage detection device with permanent magnet of NdFeB material as excitation mode and Hall element as core is put forward, and the design of software and hardware is introduced. The other part is the damage location and tracking module based on RFID technology. According to the field conditions, the 13.56MHz radio frequency reading and writing system based on IS015693 protocol is selected to construct the location module. The damage tracking display is realized. There is a complex electromagnetic environment in the coal mine, which will produce very unfavorable interference and noise to the detection signal of the wire rope detection equipment. This paper analyzes the electromagnetic environment of coal mine, puts forward various kinds of electromagnetic interference, and designs the EMC electromagnetic compatibility of the detection system.
