Abstract: This paper proposes a design scheme for a portable equipment condition monitoring and diagnostic instrument based on OMAP-L138. Its hardware and software architecture design are introduced, with a detailed focus on the hardware design of the data acquisition section and the software design of the data acquisition module. By leveraging the control processing advantages of the ARM core and the digital processing capabilities of the DSP core, the benefits of low power consumption and high performance are achieved.

Condition monitoring and fault diagnosis of industrial equipment effectively ensure the stable operation of equipment and play an increasingly important role in predictive maintenance. To meet the needs of petrochemical enterprises for condition monitoring and fault diagnosis, a portable, comprehensive equipment condition monitoring and diagnostic instrument has been designed. The design references Xinmai's OMAPL138+SPARTAN6 evaluation board. The OMAPL138 dual-core processor launched by TI possesses powerful complex data processing capabilities and reliable real-time performance, enabling high-performance dual-channel data acquisition and signal analysis, as well as on-site display of FFT spectrums, shaft orbits, and other functions. The OMAPL138 processor integrates
