摘　　要：为了提高数控测井仪器中组合测井仪等信号处理系统的实时性,提出了一种基于LPC2294的嵌入式编码信号处理系统设计方案,并完成了系统的软硬件设计。该系统的硬件部分主要以LPC2294为核心,实现编码信号的处理、测井参数的LCD显示、与上位机的CAN数据通信等功能。软件部分通过嵌入式操作系统μC/OS-Ⅱ的移植,在μC/OS-Ⅱ的平台上完成系统任务软件的设计,使得任务间容易实现相互通信和调度,提高了系统的实时性和稳定性。In order to improve the real-time of computerized logging signal processing systems especially for combination logging tool,a new embedded coding signal processing system based on LPC2294 was introduced,the hardware and software were designed.The hardware based on LPC2294 mainly realized the functions as follows：the encoded signal conditioning,the encoded signal conversion,depth signal conversion,CAN bus communication,and LCD display.Porting the embedded real-time operating system μC/OS-Ⅱon LPC2294,thus the paper completed the design of the system software.This method makes the communication easily,and it also improve the real-time and stability of the system.
