【摘要】：鋼絲繩具有很強的過載能力、抗拉強度以及抗疲勞強度等特點,在煤礦生產(chǎn)作業(yè)中得到了廣泛的利用。在礦井往井下運輸人員的架空人車系統(tǒng)中,鋼絲繩作為架空人車運輸?shù)某休d體,它的安全性及使用狀態(tài)關(guān)乎工人生命,對于其損傷的實時在線無損檢測顯得至關(guān)重要。由于鋼絲繩不間斷地運行,損傷部位被檢測到后將隨著系統(tǒng)的運行遠離鋼絲繩檢測裝置。所以對于損傷的定位、實時跟蹤與狀態(tài)顯示也是檢測系統(tǒng)一項重要功能指標。研究一種實時高效并能跟蹤狀態(tài)的鋼絲繩檢測系統(tǒng),可以為礦井工作人員對架空人車鋼絲繩的狀態(tài)監(jiān)控與維護更換提供重要的數(shù)據(jù)支持與參考意見。 本論文采納了當前鋼絲繩檢測理論的優(yōu)秀研究成果,基于強勵磁狀態(tài)下的漏磁原理設(shè)計了架空人車鋼絲繩無損在線監(jiān)控系統(tǒng)。根據(jù)礦井現(xiàn)場架空人車運行系統(tǒng)中鋼絲繩的損傷特征以及運行特征,將鋼絲繩檢測系統(tǒng)分為兩大部分設(shè)計：一部分是主檢測系統(tǒng),利用磁偶極子理論對鋼絲繩損傷漏磁場特征進行建模并仿真,提出以釹鐵硼材料的永磁體為勵磁方式、以霍爾元件為核心的漏磁檢測裝置方案,并對軟硬件進行設(shè)計介紹；另一部分是基于RFID技術(shù)的損傷定位跟蹤模塊,根據(jù)現(xiàn)場條件,選定基于IS015693協(xié)議的13.56MHz射頻讀寫系統(tǒng)對定位模塊進行構(gòu)建,詳述定位原理并利用軟件繪制鋼絲繩運行狀態(tài)圖,實現(xiàn)損傷跟蹤顯示。煤礦現(xiàn)場存在復(fù)雜的電磁環(huán)境,會對鋼絲繩檢測設(shè)備的檢測信號產(chǎn)生非常不利的干擾及噪聲。文章對煤礦電磁環(huán)境進行分析,提出存在的各類電磁干擾,并針對性地對檢測系統(tǒng)進行EMC電磁兼容設(shè)計。
[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.
