Study of Remote Control of Non-OS Embedded Instrument Based on LXI Bus Technology

A scheme is proposed to realize remote control of embedded instrument without operation system under the mode of B/S structure in view of its self-limitation. Advanced LXI bus technology is usually employed to replace the traditional bus technologies, by which the remote network control can be realized. Due to its, small resource characteristics of embedded instrument, LwIP protocol stack is transplanted into the instrument for realization of the simple TCP/IP protocol function, Web server function is applied to the instrument. The method takes existing low-end instrument as a foundation, combines CGI with the embedded instrument for interactive operation and finally realizes the remote control of embedded instrument through LAN interface.
