The design is based on magnetic flux leakage principle, the use of Hall sensors to detect magnetic flux leakage signals, magnetic flux leakage sensor analog signal that directly to the circuit input voltage signal, through followup circuit and software processing, Wire Ropes pleted the task of designing nondestructive testing . Signal processing system consists of three operational amplifiers with high mon mode rejection ratio amplifier and low pass filter circuits, the realization of Wire Ropes signal amplification and filtering, through the amplification, filtering the processed signal through the ADC0809 for A / D conversion, converted data access microcontroller AT89C51, through software programming, the MCU control LED displays the voltage value, and by the number of LED lights to judge the situation Wire Ropes. First of all programs written in the Proteus simulation software, in theory, AD conversion and data to achieve the basic functions. In the simulation based on the schematic drawing of the system built in the universal test circuit board, and has been debugged, to achieve the desired objectives. This design not only to detect internal defects in steel wire rope and wire rope metal cross section can be quantitatively detected. Online realtime detection of all rope, high efficiency, free from anthropogenic influence factors, bined with manual inspection and quantitative analysis of test data to evaluate the extent and intensity of wire rope damage losses.KEY WORDS：Wire rope ,Hall sensor, Amplifying ,Filtering,A / D conversion, SCM 目 錄前 言 1第1章 鋼絲繩無損檢測的分類 2第2章 鋼絲繩無損檢測裝置設計 3167。 斷絲的漏磁場檢測 3167。 鋼絲繩的磁化方法 4167。 檢測元件 5167。 感應法 5167。 霍爾效應法 6第3章 信號調理電路設計 8167。 信號調理電路 8167。 放大電路 8167。 LM741運算放大器 10167。 電源供應器 10167。 濾波電路 11第4章 硬件電路及軟件設計 13167。 AT89C51 13167。 ADC0809 15167。 硬件電路調試 16167。 程序流程圖設計 20結 論 21參考文獻 22
