Abstract: Through activating mode of GPRS by mobile phone short message to realize remote data transmission by double modes(mode of GPRS and mode of GSM) of wireless sensor and to accomplish complementary mutual function of two modes,reliability and stability of remote data transmission are enhanced.This paper described the detail of the realization process of this method,gave relevant programs.The system was tested in real conditions for spontaneous combustion monitoring in Xinjiang coal fields.The results indicated that this system can realize accurate and real time remote data transmission by wireless sensor networks.
