基于CPCI总线的接口卡设计

Design of interface card based on CPCI bus

针对某弹上记录器的性能测试设计了地面测试设备。由于数据传输速率较快、数据量较大,为了提高测试设备接收、处理数据的能力,研究了基于CPCI总线的接口卡设计,既能实现准确接收,又能高效处理记录器下传的高速数据。经过实际验证,接口卡能够准确接收大量的高速数据,并能通过CPCI总线实时地上传给上位机进行显示和存盘,具有很高的可靠性。

For the performance tests of a recorder on the missile, a ground test equipment is designed. Due to the rapid data transmission rate and large amount of data, in order to improve the test equipment receiving and data processing ability ,a research on the design of interface card based on CPCI bus has been given, by which the high-speed data from receiving recorder can be transmitted accurately and processed efficiently. Through the actual verification, interface card can receive a large number of high- speed data, and upload data to the epigynous machine for display and save by CPCI bus in real time. It has very high reliability.
