Development of PTS data acquisition and processing system based of LAN technology

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.
