摘要
为提高活塞环漏光度自动测量的准确性、实时性及解决相机旋转绕线问题,设计了一种基于FPGA与DSP的嵌入式处理系统。阐述了系统总体方案、硬件架构和软件设计等方面内容。结合角编码器提供外触发信号,利用无线收发装置与上位机进行指令和数据传输,并通过旋转连接器为系统供电,有效保证了系统测量的准确性和实时性,并从根本上解决了相机旋转绕线问题。实验证明,系统测量结果准确,重复误差不大于2°,满足相关标准及工程应用要求。
Light leak degree is one of the most important parameters of piston ring.To make the automatic measuring instrument of piston ring light leak degree more precise and real-time,and solve the problem of rotation winding of camera wire,an embedded system based on FPGA and DSP is designed.The paper introduces the overall design scheme,and hardware software architecture of the system.Combined with an angle encoder to provide external trigger signal,a wireless transceiver to transmit instructions and datas with computer,and a rotation connector to supply the system with power,the accuracy and processing speed of the system are effectively guaranteed.Meanwhile,these methods solve the problem of camera wire winding fundamentally.Experiments show that the system measures light leak degree accurately and has a good repeatability,and meets the requirements of relevant standards and engineering application.
