基于VxWorks的油井多参量采集系统设计

Design of the well many paramete acquisition system based on VxWorks

阐述了在VxWorks环境下PC104油井多参量采集系统的开发过程,设计开发了采集系统的板载支持包BSP,完成了油井多参量采集模块的驱动,使系统有效地支持A/D转换通道来采集现场各种仪表数据。在VxWorks中,能更容易满足油井多参量采集系统的实时、多任务调度要求,并且在不了解系统硬件结构的情况下,方便地进行后续应用程序的开发,从而缩短系统开发周期。

This thesis discusses the development process of the PC 104 well many parameter acquisi-tion system in VxWorks environment , designing and developing the BSP , finished well many parameter acquisition module driver .It makes the system effective support A/D conversion channel to collect the various kinds of instrument data .In VxWorks environment , can be more easily meet the real -time task scheduling requirements of the well many parameter acquisition system , and the developer don＇t know the system hardware structure ,they can be easily engaged in the subsequent application development , so as to shorten the system development cycle .
