摘　　要：国内外早期,探测器装置的数据传输系统普遍采用并行总线架构,如VME、PXI总线等。随着核物理实验的发展,数据的传输速度不断提高,并行总线难以提速的弊端逐渐显现,总线速度不够导致数据无法通过背板传输。本工作采用基于MicroTCA(Micro Telecom Computing Architecture)架构设计一种新型先进的数据传输AMC(Advanced Mezzanine Card)信号处理卡。该AMC信号处理卡的背板总线使用在速度提升方面有着巨大优势的高速PCIe串行总线。通过测试验证,整个传输链路传输功能正确,链路传输的光纤误码率低于7.62×10^(−15),传输速度也接近理论的极值,达到了430 MB/s。最后,该AMC信号处理卡与前端电子学进行了联测,验证了系统的正确性。In the early stage,parallel bus architecture,such as VME and PXI bus,is widely used in the data transmission system of detector devices at home and abroad.However,with the development of nuclear physics experiments and the improvement of the speed of data transmission,the drawbacks of the difficulty in speeding up the parallel bus gradually appear.The data can not be transmitted through the backplane due to the low bus speed.In this paper,we design a new advanced data transmission Advanced Mezzanine Card(AMC)signal processing card based on Micro Telecom Computing Architecture(MicroTCA).A high-speed PCIe serial bus which has significant advantages in speed improvement is used in the backplane bus of the AMC signal processing card.The transmission function of the whole transmission link is tested and verified to be correct and the fiber error rate of the link transmission is lower than 7.62×10−15.The transmission speed is also close to the theoretical extreme,reaching 430 MB/s.Finally,the AMC signal processing card and front-end electronics are tested jointly,and the validity of the system is verified.
