Pla N · 2009
In order to extend the manner of alarm signal,the GSM-based communication technology is researched in this paper. Based on the SIEMENS TC35I module,a GSM equipment is developed,which can be controlled by computers for GSM messages sending and receiving.Two kinds of development interfaces are provided for programmers to use this GSM equipment easily. Experiments and applications show that this equipment has the maximal ability of 400-600 messages per hour.
