Portable Machine Condition Advisor (PMCA) Based On DSP

Plant monitoring and diagnose has developed rapidly in recent years. It effectively ensures the stably running of plant, and will play a more and more vital role in the plant predictive maintence. And the development of embedded system and computer technology offers a new orientation of plant monitoring and diagnose.Portable Machine Condition which treats DSP as its MCU is developed to meet the demand of plant monitoring and diagnosis in Petrochemical Enterprises. It also provides signal conditioning of pump base unit, sampling, data processing, displaying of time-domain waveforms and frequency spectrum, temperature measurement using an infrared sensor, communication with external interface and so on. Full consideration to signal integrity, I designed the PCB of Machine Condition Montioring system with the help of Altium Designer, and optimized the PCB design to ensure the stably running of plant, using Hyperlynx to simulate. To write and debug the code of vibration signal acquisition, temperature signal acquisition, real-time clock, displaying, data storage of SRAM and data storage of Flash by using Code Composer Studio and C programming language.Technology of plant monitoring and diagnosis is illuminated briefly in the paper. And comprehensive analysis is given for the hardware design, which includes signal conditioning, sampling, Microprocessor and power. It also gives the simulation of key signal and improves the hardware design. The design and structure of software is set forth.
