摘　　要：CAN/GPRS无线车载网关是整个汽车内部网络与外界交互的数据出口,具有举足轻重的作用。通过项目开发实例,给出网关的具体实现,包括硬件的设计、软件的编写、操作系统的移植、协议转换和无线通信等内容。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 included also GPRS wireless networking and socket communication.
