| Abstract: | This paper proposed a method of combining two types of data service, CSD and GPRS, based on GSM for remote wireless monitor system. Using this method, the network structure of the system was put forward. Then it implemented CSD and GPRS hardware interface and software flow based on MC35i radio communication module. Compared with traditional single mode of GPRS, this method compensated the disadvantage of high delay and uncertainty in data transmission, guaranteed the real-timeness of data transmission and reduced daily maintenance expense. Field test indicated that this method is of high practicability and validity. |
