摘　　要：针对传感器阵列数据链路经常出现传输异常问题(包括数据丢包、时钟故障、链路断开等),为快速确定故障原因并定位故障位置,采用网络处理器设计了一种针对大规模传感器阵列的数据传输链路故障诊断桥接模块,并配合相应的上位机软件,可以快速定位数据传输链路中故障的位置以及故障原因。通过实验验证分析,该故障诊断桥接模块可快速实现传输链路中常见故障的检测、定位和分析。该检测模块大大缩减维修人员维修设备时故障排查时间,提高了检修效率。Because sensor array data links often have abnormal transmission problems(including data packet loss,clock failure,link disconnection etc),in order to quickly determine the cause of the fault and locate the fault location,a network processor is used to design a large-scale sensor array data transmission link fault diagnosis bridge module.Together with the corresponding upper computer software,it can quickly locate the location of the fault in the data transmission link and the cause of the fault.Through experimental verification and analysis,the fault diagnosis bridge module can quickly realize the detection,location and analysis of common faults in the transmission link.The detection module greatly reduces the troubleshooting time of maintenance personnel when repairing equipment,and improves the efficiency of maintenance.
