Design and Implementation of a High-speed Data Acquisition Tomography System

In order to implement online real-time non-destructive detection of turbine fluid distribution and the internal operation of the rotating machinery, we designed a high-speed data acquisition system based on PCI7300A and a high speed microcontroller—UBICOM. It is also for a further goal of carrying on graphical fault diagnosis and fault-tolerant control. This paper describes the system structure and introduces the methods used to implement the system, as well as the design concept and the principle of this program. The practical application showed that the system can realize online real-time collection of tomography projection data, and the acquisition speed can be up to 80M bit/s. Thus nondestructive testing of a rotary mechanism with a high rotation speed of 5000 r / min could be achieved.
