Design and realization of the substation real-time short message sending system based on GSM/CDMA

In the remote real-time monitoring of the substation operation equipment,the installation of communication equipment is often restricted and communication channels are often disturbed by a wide range of complex factors,which greatly treat the secure operation of power grid.This paper introduces the program of how to realize the remote,real-time and wirelessly transmission of substation information with the application of SMS technology based on GSM and CDMA mobile communications.The design idea of this program is that accessing real-time data at first from substation monitoring system database,and then sending the processed database by the software,to specific personnel through a special industrial GSM/CDMA module.As the GSM/CDMA networks have a broad coverage and short messages can be sent reliably,the SMS could effectively solve the problem that the information transmission is on dependence of communication channels,eliminate a large number of potential security threats,and will greatly improve the reliability of the substation operation.
