Abstract: Recently, attentions are focused more on vehicle interior network application and the wireless vehicle-carry data transmission technology. For developing a remote monitoring system, three aspects of the system are discussed: the vehicle interior network configuration, the CAN/GPRS gateway realization and the remote monitoring server design. Described in the paper are hardware design, programming of low level drivers, the network application layer protocol design, the ARM-Linux transplant and the protocol conversion. Contents include GPRS wireless networking and socket communication.
