Research On The Identification Recognition System Of Cold Wheel Steel Billet

Quality of the merits of the train wheels plays a vital role in the safe operation of trains, but wheel company traditional production scene management lack of effective monitoring for online quality fluctuations and quality tracking. Therefore, the establishment of wheel identification system in the whole production process and record manufacturing information is of great significance to achieve the wheel quality tracking.In this paper, with the aid of the image scanner, combined with the PLC and force control monitoring configuration technology, the identification of steel billet in the process section of steel rolling heating manipulator is realized.This paper investigates the development of today's identification technology, analyzes of the material tracking cases in the steel industry and problems to be solved.Based on the analysis of the billet cutting and steel rolling heating furnace,the function and performance requirements of the system is designed.After cutting the billet by sawing machine,the printer spray unique identification code in the billet,when the billet is transported to the manipulator, the identification code is read by the image scanner,the code includes some information: billet furnace number, size, segments number, serial number, saw number and operator names, etc.The bar-code reader compares the recognized bar-code with the host computer database,consistent with the production plan of steel billet in order to enter the heating furnace, does not meet the elimination.According to the functional requirements of the system, the design of bar code identification, using the two level control structure of the monitoring system and the field control system, and the selection of industrial Ethernet to build a communication network,to complete the design of the control system of the cold wheel steel billet identification.S7-300 series PLC is choosed, the program become convenient by using the SIEMENS's STEP7 V5.5 software as development tool to write system control program in the way of ladder diagram programming language and structured programming. Host computer adopts Force Control V7.0 as monitoring configuration software,a human-machine interface of intuitive, imaginative of material tracking management system is designed by using library, animation connection, the background components and other functions.Application of this system will clear the billet order which has entered heating furnace,and establish basic data for the subsequent product tracking of the wheel and the unique identification code corresponding to the product parameters.The actual production situation shows that the application of the system to improve the degree of automation of production,increase product quality and traceability.
