摘要

It proposed a method of combining the two types of data service CSD and GPRS based on GSM applied to GPS vehicle real-time monitoring and alarming system. Based on this method, Basic constitution and network structure of the system is given out, and then it implements the CSD and GPRS hardware interface and software flow based on the GR47 wireless communication module. Arm Embedded System was used as the central processing unit (CPU) and uLinux was used as the appropriate operation system (OS) to the circuit design. Compared with the conventional single mode of GPRS, this method makes up the disadvantage of the high time delay and the incertitude of the time delay in data transmission. In this case, the real-time data transfer of the system gets guarantee, and the daily maintenance expense of the system is reduced. GIS is applied to track and alarm the hardware clients on the electronic map. The test indicates that this method is appropriately used in the instantaneous information real-time transmission, and has high practicability and validity.
