Abstract: In order to meet the demands of measuring cable-extension displacement testing instrument, the measurement and control software is developed .The software can control the high speed linear induction motor to drive the testing instrument, record the test data and realize the measurement. With the management of testing as the core task in the software, control servo system and storing data are finished by high level priority thread and timer. The experimental results demonstrate that the software design can meet the expected requirements. This software had been used in practice.
