摘要
自动化电表检定流水线的运行精度是流水线检定效果的决定性因素。为维持自动化流水线的高精度运行,提出了一种基于新型分布式算法的自动化流水线精度改进方法。该方法首先着重于算法的改进,不同于传统的分布式算法,所提出的分布式算法侧重于对传统算法中查找表中的值进行重组优化;然后在改进算法的基础上进行了结构的最优化设计,特别是采用了查找表分割的方法实现资源最小化;最后,该方法在FPGA上得到了实现。该方法以检测精度最优化为目标,综合考虑流水线各个环节的具体运行状态,以取得自动化检测效果最优化。经具体实践测试,该方法不仅提高了电表的检定效果,而且还有效地减少了对系统各类资源的占用。通过对目前已经投入现场作业的系统进行实际检测,证明该方法取得了优异效果,值得在相关检测系统中大力推广。同时,所提出的新型滤波器算法也将对现有的数字信号处理研究产生影响。
The operational accuracy of automated smart meter calibration line is the key factor that determines the effects of the calibration line. To maintain the operational accuracy at higher level,the modified method based on a novel distributed arithmetic is proposed. Firstly,the method focuses on the modification of algorithm. Unlike the traditional distributed arithmetic,the proposed algorithm; mainly reconstructs and optimizes the values stored in the lookup table of traditional algorithm,then on the basis of the modified algorithm,the optimal design of the structure is conducted; especially a lookup table decomposition strategy is employed to reduce the resource usage; finally,the method is implemented on FPGA platform. With the optimal accuracy as the target of design,and based on the comprehensive consideration of the specific operational state of each section of the calibration line,the optimization of the effects is obtained. Through practical testing,it is found that the proposed method not only improves the calibration effects,but also effectively reduces the resource occupation. It is further found that the method is worthy to be popularized in other detecting systems,meanwhile,the proposed filter algorithm will impact the present digital signal processing research.
