[Abstract]:The technology of condition monitoring and fault diagnosis provides an effective guarantee for the safe and stable operation of industrial machinery and equipment, which makes the fault diagnosis and analysis instrument based on embedded technology widely used in the management and maintenance of industrial machinery and equipment. The purpose of this paper is to meet the need of intelligent inspection and fault diagnosis analysis of distributed machinery and pump equipment in petrochemical enterprises. The hardware processor of the inspection and fault diagnosis instrument is Samsung S3C2440A, and other hardware modules are attached according to the actual functional requirements. Based on Windows CE5.0 operating system, an embedded software system for inspection and fault diagnosis is developed. This paper focuses on the development and optimization of embedded operating system and driver, and expatiates on the development of embedded software system combined with inspection and fault diagnosis instrument. Firstly, on the basis of studying the function and principle of the boot loader Bootloader, considering the actual requirements of the inspection and fault diagnosis instrument, the fast start boot file Fastboot, used in the product release of the inspection and fault diagnosis instrument is developed. The display of LOGO picture is realized in Fastboot. Secondly, the kernel structure and components of Windows CE5.0 operating system platform are studied. Through the process of operating system customization of inspection and fault diagnosis instrument, the modification and optimization methods of system transplant customization and system memory allocation based on Windows CE5.0 platform are expounded. Finally, the interrupt handling mechanism and driver model of the Windows CE5.0 platform are analyzed, and the LCD display driver of the inspection and fault diagnosis instrument is modified and transplanted. The battery coulometer module driver, the speed measurement driver and the data acquisition module driver are developed by using the current interface driver model. The usability of the driver is also tested with the application program. The inspection and fault diagnosis instrument designed in this paper has been used in some petrochemical enterprises. The practical use proves that the instrument can run stably and reliably, which meets the needs of the petrochemical enterprises for the pump group inspection and fault analysis.
