摘要
Abstract
On the basis of analyzing the current manual verification method,the automatic verification method of ultrasonic flaw detector with remote control interface is studied,and the automatic verification system is designed and developed.With the extensible markup language (XML),equipment remote control instruction set and data analytical method library are established,which can solve the problems of the extension design of the instrument interface and protocol diversification;with signal generator and a programmable attenuator cascade,controlled attenuator used in metrology is designed,the high accuracy controllable attenuator bottleneck is broken through effectively,and the problems of large attenuation range,small attenuation step and high attenuation accuracy are all solved.For the verification of the scanning range parameters of the ultrasonic flaw detector,the calculation method is proposed to replace the traditional counting method,and the verification process is realized.关键词
