摘　　要：为了能够精准确定由无效磨损行为导致的锥颈面磨损位置及磨损程度,提出并设计了基于可变载荷的锥颈面磨损检测系统。以时钟配置电路作为底层电子输出元件,同时连接数据链路层主机与软核检测处理器,实现检测系统的硬件执行环境搭建。在此基础上,配置媒介工作模式,借助已成型的PHY初始化检测程序,控制GigEVision检测协议的执行状态,实现系统的软件执行环境搭建,再结合相关硬件设备结构,完成基于可变载荷的锥颈面磨损检测系统设计。对比实验结果表明,与常规FPGA型磨损检测系统相比,基于可变载荷的锥颈面磨损检测系统的UTI与STI指标数值水平更高,能够有效确定锥颈面的无效磨损行为,从而实现对锥颈面磨损位置及磨损程度的精准确定。In order to accurately determine the wear location and the degree of wear on the taper neck surface caused by ineffective wear behavior,a taper neck surface wear detection system based on variable load is proposed and designed.The clock configuration circuit is used as the bottom electronic output component,and the host of data link layer is connected with the soft core detection processor to realize the hardware execution environment of the detection system.On this basis,the media working mode is configured,and with the help of the formed PHY initialization detection program,the execution state of GigE Vision detection protocol is controlled,and the software execution environment of the system is established.Combined with the related hardware equipment structure,the design of cone neck wear detection system based on variable load is completed.The experimental results show that compared with the conventional FPGA wear detection system,the value of UTI and STI indexes of the cone neck surface wear detection system based on variable load is higher,which can effectively determine the invalid wear behavior of the cone neck surface,so as to realize the accurate determination of the wear position and wear degree of the cone neck surface.
