从CAN总线到VXI总线数据传输的实现

Data Transmission from CAN Bus to VXI Bus

在VXI总线系统中,为了能够获得大量实时数据,需要利用CAN总线快速可靠地传输数据的性能,设计一种混合VXI总线和CAN总线的系统。在这种混合系统中要实现CAN总线上各个节点采集并传输实时数据,采用VXI-CAN这样一个消息基模块完成数据到VXI总线上的传输。通过这种VXI总线和CAN总线互相通讯获得实时数据的基本原理和方法,实现了实时数据的采集。这种数据传输的实现为VXI总线系统的设计拓宽了新的思路。

In order to acquire a large number of real-time data, CAN bus can be used in the VXI system. Taking the advantage of CAN bus, a mixed system of VXI bus and CAN bus is designed. In such a system, a VXI-CAN message-based module can be used to connect VXI bus and CAN bus. In this way, each node on the CAN bus can acquire and transmit the real-time data. The principle and approach of data transmission make the data-acquisition reapized between VXI bus and CAN bus, which helps us to find a new way to design a data-acquisition system.
