This paper studies the key technologies of digitization from three aspects:digital transformation approach, data processing and analysis, and equipment long-cycle management. Digital technology of ray detection has the advantages of high sensitivity, high resolution, low dose, online monitoring, remote sharing, etc., and it mainly includes:CR/DDA/CT technology, cold cathode X-ray imaging technology, pipeline digital automatic inspection technology, pipeline corrosion ray digital detection technology. The digital data processing and analysis mainly includes the superposition and overlapping of original negative signals, the auxiliary automatic identification of defects, and the evaluation of 3D modeling quality. Equipment long-cycle management is to realize multi-directional and full-life management and control through the construction of equipment information management platform. The above three aspects are combined to achieve detection data fusion, cloud storage and remote monitoring functions.
