Design of Testing System of Integrated Parameters of Engine Based on Technology of Parallel Procession of Multi-DSP

In order to realize the integrated testing of dynamic parameters, real-time and in-system inspection, and diagnoses of fault of engine, at the same time considering the universal and specific performance, a new-fashion real-time testing system design for the integrated parameters of engineer is proposed based on the technology of parallel procession of multi-DSP and virtual instrument. It especially introduces the design of the structure and frame-saw of the system hardware and software. Furthermore, the theory of real-time and long-distance diagnosing about system faults is discussed simply. The actual application of system has increased the measuring precision and work efficiency remarkably, and simultaneously provided the credible ensure for in-system and real-time inspection and diagnoses on faults.
