摘要
在我国,无论是煤矿还是冶金矿所使用的提升设备都普遍存在着钢丝绳磨损的问题,尤其是斜井提升设备上使用的钢丝绳,最突出的问题就是钢丝绳磨损,直径变细。我国《煤矿安全规程》规定,矿用提升钢丝绳断面积减小 5% 时,不能用来提升工作人员;断面积减小 10% 时,不能用来提升矿用物资。而提升钢丝绳的提升能力及使用状态对于提升设备的安全可靠运行至关重要,因此,每天必须对提升钢丝绳进行检测,以确保提升设备的安全可靠运行。目前,厂矿企业仍然沿用传统的人工检测方法,即人工使用游标卡尺进行抽点检测。这种检测方法存在着很大的弊端,它检测精度低,不能进行连续的实时在线检测,漏检的情况也时有发生,这就给提升安全带来严重隐患。同时,这种方法劳动强度大,检测速度慢。另外,在进行人工检测时,提升钢丝绳必须停止提升,这样会降低工作效率和设备利用率。而且人工检测全凭实际工作经验,精度、效率也会随之降低,既不能完成非接触检测,又不能实现在线检测,同时还增加了检测时给工作人员所带来的危险性。针对这种现状,国内外各高校及研究部门对提升钢丝绳直径的连续实时在线检测进行了大量的研究工作。从检测方法看,主要有两类:磁通检测法、激光扫描法,但这两种检测方法都存在着较大的缺点。磁通检测法检测精度低、设备笨重;激光扫描检测法虽然检测精度高,但是设备复杂、成本高。在这种情况下,D技术本文提出了一种新的提升钢丝直径测量方法—— CCD 实时在线非接触式线径测量数码管显示具有测量快速高效自动化程度高示直观等特点并能克服人工检测所具有的缺点.

Abstract
In our country, whether or metallurgical coal mine upgrade equipment used by the wire rope wear is prevalent problem, particularly the inclined shaft upgrade equipment used wire rope, the most prominent is the issue of wire rope wear, small diameter. China's "coal mine safety regulations", mine hoisting cable basal area decreased 5%, should not be used to enhance staff; basal area decreased 10 percent, can not be used to upgrade mine supplies. Wire Rope for upgrading and enhancing capacity and the use of state equipment to upgrade the safe and reliable operation of utmost importance, therefore, must be to upgrade the rope daily testing to ensure that lifting equipment safe and reliable operation. At present, mining enterprises are still using the traditional methods of detection, the use of a vernier caliper pumping detection. This test is the presence of large defects, it detects low accuracy but not continuous real-time detection, missed the situation occurred from time to time, which to enhance security serious hidden dangers. At the same time, this method labor intensity, slow detection. Meanwhile, in artificial testing, must stop hoisting cable upgrade, which will reduce efficiency and equipment utilization. Detection entirely artificial and practical work experience, accura
