Abstract: In accordance with the national standards of pre-stressed strand stretching experimentation and the deficiency of its tracking- identification-command system at the present, this paper comes up with a tracking-identification-command system of pre-stressed strand stretching experimentation based on a JL-2008 USB data collecting instrument, elaborates on the fulfillment of its hardware and software and the design of its relevant programs, then summarizes that the tracking-identification-command system bore several advantages such as low cost and power consumption, high reliability and general purposes, high test accuracy and convenient measurement.

Key words: USB interface, data collecting instrument, tracking-identification-command system
