设计了基于FPGA控制的LVDS总线冷备份测试系统,通过实验研究了伽玛暴偏振仪(PO-LAR)数采系统中带有冷备份设计的LVDS总线在不同数据传输速率下的稳定性。测试结果表明数据传输速率在100Mbps以内带有冷备份设计的LVDS总线是稳定可靠的。为POLAR数采系统中LVDS总线冷备份的设计提供了一种可靠的方案。
It designs the LVDS testing system with standby redundancy based on control of FPGA. Through experiment, the stability of LVDS with standby redundancy in POLAR data-acquisition system at different data transmission rate was studied. The experiment result indicates that LVDS with standby redundancy is stable with data transmission rate under 100Mbps, and provides a kind of reliable scheme for design of LVDS with standby in POLAR data-acquisition system.
