Research and Realize the Key Technology of the Soft System For Instrument Platform Based on the Embedded Linux

With incessant development of the information technology and incessant increasing of the users' requirement, the embedded system is applied widely. The embedded system can greatly satisfy the guideline request advanced by instrument system, such as the characteristic of real time, dependability, power-consume and so on. This paper expatiates the key technologies in soft design and the realization methods of some functional soft modules for instrument platform based on the embedded system, including: the serial develop technology, the net develop technology, LCD/VGA display technology, the realization of the SCPI command Interpreter; the realization technology of the GUI graphic interface. All above soft modules' realization can extensively shorten develop time of soft system, and increase readability of the test program and instrument's crossing-over ability. The embedded instrument platform based on these technologies has better practicality value and wide application significance, which plays a active role in support to drive our country embedded instrument's development.
