Development of an Instrument for Machine Equipment State Inspection and Safety Evaluation Based on Embedded Technology

In modern industry, plant equipment must be maintained effectively to guarantee safety operation. An intelligent instrument for plant equipment state inspection and safety evaluation was developed based on embedded technology. Firstly, the overall structure of the instrument system was introduced. Then the mainboard circuits were designed based on ARM core microprocessor. The control logics of the dynamic machine signals acquisition subsystem were designed by using of a complex programmable logic device. After that, the embedded operating system was transplanted and device drivers were programmed. Finally, the functions of the applications were stated. The designed instrument can meet the needs of the vibration acquisition of the rotating machines satisfactorily and provide effective means for equipment maintenance.
