The design of the GSM modem SMS voice synthesis system based on XF-S4240 voice synthesis module and Smart ARM-2200 embedded develop platform are introduced.

The system,on receipt of enquiry about line tripping from power dispatching or other personnel through GSM MODEM,compiles information on name of transmission line and time of tripping through decoding,automatically search for tripping from tower alarm database of lightning location system,and feeds back the enquiring result through short message to relevant personnel.

The inquiry of a part of passengers about the public traffic transfer is made and a short message inquiry platform based on the technology of GSM MODEM is constructed.
