摘要
设计一款基于LPC1788微控制器的WTS地面接收卡,实现ECLIPS-5700测井仪器配接所必需的测井数据解码、命令编码、仪器程控供电和推靠控制等核心功能,同时板卡上集成深度、张力等信号的采集功能。在详细介绍板卡硬件平台和各子模块功能的基础上,重点阐述LPC1788主控模块的硬件时序及软件设计,建立基于LwIP协议栈的以太网总线通信,实现与上位机之间的信息实时交互。慧眼2000成像测井系统的应用实践表明,板卡功能集成度高、性能稳定、通信可靠、便于扩展,很好地达到了预期目标,能够满足成像测井对于数据传输的需求。
A novel WTS surface receiving board based on LPC1788 is designed to implement the core functions of ECLIPS-5700 logging tools such as logging data decoding,command coding,programmable power supplying,pushing control and so on.Meanwhile,the acquisition functions of depth,tension signals are integrated on the board.On the basis of a detailed description of the hardware platform and sub-module function,the hardware sequence and software design are elaborated emphatically,the Ethernet communication based on LwIP protocol stack is established to achieve real-time information interaction to PC.The application of HY2000 imaging logging system shows that such a decoding system is high integrated,stable,reliable,and convenient to expand.The data transmission requirements for imaging logging are satisfied,and the design goals are well achieved.
