摘要
针对PTS装置电参数测试及数据处理提出的集中远程控制、实时数据采集、试验后数据处理等实际需求,研制了基于局域网技术的数据采集、处理系统。选用内嵌以太网络接口的示波器完成信号采集,以计算机为仪器远程控制及数据采集、处理的核心,网络数据传输基于TCP/IP协议。系统软件以Visual Basic 6.0为开发平台,通过VISA调用底层驱动实现示波器控制,完成多路数据同步采集,并通过计算机与装置主干网络的上行互联完成试验数据交换和数据共享。
A data acquisition and processing system based on LAN technology was developed according to the actual demands of integrated remote control,real-time data processing and data processing required by PTS.The oscillograph with embedded Ethernet interface was chosen to fulfil signal acquisition.A computer was taken as the core of instrument remote control and data processing.The network data transmission is based on TCP/IP protocol.Visual Basic 6.0 is used to exploit the virtual instruments of the system.VISA is adopted to realize the remote control of oscillographs.The data exchange and sharing are accomplished through network.Thus the paper points out a future research direction about the technology of interconnection of the control and monitoring system for multi-oscillograph device and information network.
