With the development of the microelectronics technology, computer technology and network technology, software technology and the height of measure and control technology and instrument in electronic application, a new measurement method, measurement field theory, and the new instrument structure has come up, in many aspects of the concept, has broken through the instrument of measuring instruments electronic function and role. In this context, the late 1980s the U.S. has successfully developed a graphical computer language - LabVIEW.
As a modern product machines in operation, the key equipment malfunction or failure causes serious consequences, not only caused great economic losses, and even cause bad social effect. Based on the above reasons, design a kind of stability, reliability and safety control of the software are particularly important. Virtual instrument, computer software and hardware platform, help build based on computer test and control system. LabVIEW virtual instrument as the representatives of language, is builed for measurement and control system.
This paper introduces the test system based on the real-time labview. The human-machine interaction, data acquisition task completed by the computer will more convenient and security. The measurement and control system in the computer application software is developed on the Labview platform, realized the friendly human-machine interaction, simple and intuitive field data monitoring, safe and reliable fault handling measures etc. Function. The real-time systems can of dc motor and stepper motor start-up process real-time data acquisition, storage and analysis.
