【摘要】 介绍一种基于uClinux系统平台的调试台架前端机软件设计方案,软件由驱动程序和应用程序两部分构成。为满足仪器测试中实时高速大数据通讯要求,实时控制局域网总线(CAN)和井下仪器总线(DTB)通讯功能由驱动程序完成。应用程序实现人机交互、与上位机网络通讯等实时性要求不高的功能。驱动程序与应用程序之间的信息交换由异步通知信号实现。所提方案已成功应用到微电阻率扫描、阵列感应、多极阵列声波等系列化成像测井仪器调试台架之中,并且加快了这些仪器的研制及维护效率。更多还原

【Abstract】 A design conception of front-end computer software based on uClinux for logging tools test-bench was described.The front-end software is capable of high-speed asynchronous communication and expandability,and composed of user program and device driver.The urgent tasks such as controller area network and downhole tool bus communication are implemented in the device driver,and meanwhile non-emergency tasks are processed in the user program.The data exchange between user program and driver is implemented through asynchronous notification.The test-benches of serialization imaging logging instruments for micro-resistivity image tool,array induction tool,multipole array acoustic tool and so on,which are based on this software,are successfully designed and developed.更多还原
