Research Of Wire Damage Real-time Online Detection System

Wire rope as essential for production and life of the parts,widely used in a variety of industries,as an important part of the traction rope and the safety and reliability of the bearing,it should not be ignored,if the rope break safety accidents,will cause significant economic losses and casualties.However,it is very difficult to detect the defects of the wire rope from the field operation conditions and the complex structure of the wire rope.Therefore,it is very urgent to study the effective detection system of wire rope broken wire,damage and defect,which can effectively detect the information of wire rope,and ensure the safe operation of wire rope.In this paper,the damage detection of the steel wire rope is carried out by using the principle of weak magnetic detection,and it is based on DSP.In this paper,the main method for wire rope and wire rope damage identification principle of weak magnetic detection are introduced,and the detection system hardware design,mainly includes the processing of DSP data,sensor and encoder input part and data based on the LCD display part.Weak magnetic sensor wire rope damage information after A/D transformation,DSP signal processing,through the LCD display of the test result,provide the wire rope damage location information using stroke encoder.In this paper,the power supply module,signal acquisition module,DSP circuit,data storage,communication interface,keyboard input,travel encoder,LCD module circuit design.The function of the system is more complete,lightweight and convenient,which meets the hardware requirements of the real-time detection system of steel wire rope.The software part of the on-line detection system of the steel wire rope,through the transplantation of the file system,the preparation of the graphics library,to achieve the results of wire rope detection on the LCD screen display.According to the actual situation of production and application,the software system is divided into "online detection" and"detection records","information system" and "system settings" four menu,each menu are mutually independent,clear structure,convenient operation and timely troubleshooting personnel records,improve the rapidity real time detection.Finally,the field experiments were carried out on the wire rope online detection system of this design,testing of wire rope damage identification ability,through on-site testing,the system can distinguish broken wire rope effectively,local defects,can effectively identify the damage location,and compared with the actual test.The results with the actual damage position is consistent,reached the design requirements,to achieve the purpose of real-time online detection of wire rope.
