一种基于FPGA的CAN总线计算机测试系统设计

Study for a Test System of Computer Based on CAN bus

为了测试纺织机机载计算机的性能及模拟其运行过程,提出了一种对机载计算机基于CAN总线的测试系统,给出了面向应用的CAN总线报文协议,介绍了通信节点的系统协议,阐述了功能结构和基于FPGA软硬件的通道实现过程,实际测试表明,该测试系统能够良好地实现通信,达到了有效评估被测计算机的目的。

In order to test the capability and imitate the running process of computer on spin machine, a test system of computer based on CAN--Bus is introduced, its structure and the design and realization of the test paths hardware and software based on FPGA are discussed. The implementation of communication of the application system is introduced. It is proved in the real test that the test system can communi- cate with computer and work well, and achieve the purpose of evaluating the tested computer.
