GSM-based short message wireless communication technology is widely used in water conservancy, electricity, environmental protection, transportation, anti-terrorism, natural gas and natural disasters due to its advantages of timely information transmission, long range, low bit error rate and low cost. Based on the establishment of a case, this paper explores the application mode of GSM-based short message technology in the field of early warning GIS, analyzes several common key technologies and specifications used in the application, extracts the common problems of this application mode, and finally makes an objective prediction and prospect on the development direction of this application mode.
