摘要
车载通信系统实现车载电子设备间的实时通信功能,需同时处理多个节点的数据传输;Linux操作系统因其多任务处理能力、源代码开放、内核高效稳定、广泛的软硬件支持等优点,广泛地用于自动控制、数据通信等领域;Linux内核系统提供了对IEEE 1394b总线的支持;文章将在Linux内核提供的接口函数的基础上,设计程序实现基于IEEE 1394b光总线的车载计算机平台的多通道等时数据的发送和接收,并验证程序能否正确的传输数据。程序测试得到接收数据与发送数据一致,满足设计要求。
Vehicle--carried communication system accomplishes the real time communication of vehicle carried electronic equipments and processes data transmission of multiple nodes. Linux operating system is capable of multi task processing and open-- source. It has a high--efficient and stable kernel and supports many kinds of software and hardware. Due to these advantages, it is widely used in auto con trol and communication fields. Linux kernel also provides supports for IEEE 1394b bus. This paper will design program to realize multi- channel isochronous data transmission and reception between vehicle--carried electronic equipments based on the program interface provided by Linux kernel and test the program to see whether it can transmit data correctly. Finally we verify that the received data is consistent with the transmitted data. The program fulfils the requirement.
