Design And Implementation Of Eddy Current Testing System Based On C#

With the rapid development of digital technology, information technology, computer technology, digital instrument has been widely used in the field of industrial detection. From the analog era into the digital era, the huge volume and highly complex electronic equipment is integrated into the IPC.Through the research of Baosteel tube factory online eddy current testing equipment, compared to the domestic and foreign equipment manufacturers integrated scheme, propose a simple universal eddy current detection system. The system is using the IPC as an integrated platform, according to the detection technology of eddy current testing equipment to design requirements. Using AD conversion card and I/O drive card to connect electrical equipment interface. Using.Net C# as the main software development platform. The system uses three layer architecture design, thread and cache implementation application modules and weak coupling interaction between the hardware. According to the different need, the business through data processing to produce different types of data flow. Using the development platform to provide user control to realize the display of modularization, using a development platform provides the function of data processing, the user controls display area use GDI+ realize data imaging. Through the abstraction, the functions of the eddy current system finally realize general eddy current testing system. Its characteristics are to have low integration costs, a good user experience, and hardware spare parts to maintain the long-term.This paper expounds the composition of eddy current testing system, key technology, demand analysis, structure and characteristics of data acquisition system and finally introduces the realization of the system.
