The Development Of Data Acquisition System Based On Vxworks

Based on rapid development of computer, semiconductor and software technology, the performance of embedded microprocessor get highly improved and the kind of embedded operating system emerge in endlessly. The embeded system gets extensive application in increasing subject. This design is an application of embeded system in data collection and controlling system.This thesis researched on the background of some radar system, adoptted the mainstream of hardware and software technology in embedded system. Following the standard designing flow of controlling system, we programmed the controlling software based on the ARM microprocessor and VxWorks embedded system.The hardware is composed of a standard PC/104 data collectting system and CS-2215 embedded computer witch is based on the ARM920T core. The embedded real time system VxWorks act as the software platform, provide excellent software surport.Corresponding to the 8 bit and 16 bit I/O address of the data collectting system, programme the I/O driver for the sake of upper application. Program the I/O in-out flow of control in the use of I/O driver. The digital datas will be collected by the A/D convertor and translated to the embedded computer. The VxWorks system provide perfect network module. Build a client procedure make use of the socket communication, so that the collected data can be transported to the computer. By making use of synchronization between assignments can highly advance the system performance.Finally this thesis introduced the Tronado host implement, board surport packedge, debug environment and compile method of the system image. We estimate the whole thesis at the end and make brief summary.
