摘　　要：利用测井地面仪中的高速采集电路、网络互连技术和虚拟仪器技术 ,研制了用于测井地面仪的虚拟示波器。虚拟示波器系统分下位机和上位机部分 ,下位机为客户机 ,上位机为服务器 ,两者通过实时网络通讯方式进行数据传输。下位机基于DOS平台 ,专门负责电路控制、信号采集和标准信号的形成。上位机基于Windows平台 ,专门负责信号的分析、处理、显示和存盘等。The paper introduces the design method of the virtual oscilloscope system that is used in logging surface instrument. The system is based on the high speed acquisition circuit, the network and the virtual instrument. The system is composed of super computer and slave computer, which can transmit messages to each other by real time network. The slave computer′s main functions cover circuit control, signal acquisition and standard signal generation based on DOS.The super computer is designed to analyze, dispose, display and store the data in PC. The system works in client/server mode in which the slave computer works as a client and the super computer dose as a server.
