Research on signal processing and storing in detection of working pipeline

The leaky magnetic flux detecting equipment is based on the theory of electric-magnetic detection. It has many advantages in detecting working pipeline such as high detecting speed, long detecting line, little undetected area, and so on. The equipment can´t be directly controlled by outside while it´s running, so detecting signals must be stored in real time. But the total data size of these signals is so large that the data must be compressed. The master slave system composed by DSP can process and store these signals rapidly and safely. It also has large capacity.
