Abstract

The paper presents a complete system for remote measurement. The system is based on the client-server communication structure over the Internet. One part considers the client application – it is used by a user to control the measurement. Second part deals with the server – the server application itself and local connection the instruments over the IEEE-488 interface bus. The communication between client and server is built on TCP connection.

Highlights

  • There is a course called “Measurement systems and their programming” at the department of Measurement, FEE CTU in Prague

  • The paper presents a complete system for remote measurement

  • One part considers the client application – it is used by a user to control the measurement

Summary

INTRODUCTION

The system is based on the server-client communication structure over the Internet. The measuring part of the system is based on the IEEE488 interface bus by which the instruments are connected to the server. Second part deals with the server – the server application itself and local connection the instruments over the IEEE-488 interface bus. Each student develops both application – client and server. The LabWindows/CVI from National Instrument is used to develop a client application. The server is running on Linux and so Linux programming techniques are taught and used to develop the server application (including communication with instruments via VISA library). The communication between client and server is built on a TCP connection
