汽车工业领域中蓝牙网关的设计与实现

Design and implementation of bluetooth-CAN gateway in automotive industry

近些年来蓝牙技术(bluetooth)已经广泛地应用在各个领域,不仅包括个人消费领域,如通信、计算机、数字照相机、家用电器等热门产品,而且还大量地应用在工业生产和服务等行业中,如汽车、玩具等传统产品.本文提出了一种用于汽车工业领域的蓝牙网关解决方案,为用户提供了无线访问控制器局域网(controller area network,CAN)的新方法,实现了蓝牙到CAN总线的无线连接,并根据蓝牙系统的传输时延和传输速率估计了该蓝牙-CAN网关的吞吐率.

Bluetooth can be used not only in the modem products such as communication, computer, digital camera, family electrical appliances, e-business, intemet and so on, but also in the traditional productions like automobile, toy, etc. A technical concept to set up a wireless connection to a CAN bus network using Bluetooth is described in the paper. This gateway is intended to be used in order to give the user wireless access to a CAN bus of generic type. The throughput of the gateway is evaluated according to the data rate and propagation delay.
