ZFYW 接收机的构成Toledo 公司原设备发出的数据是由随设备带来的500、510或8810、8820、8830、8805等具有20mA 电流环的打印机接收打印出来的,现在这些打印机在市场上已没有销售,坏了维修也没有备件。为解决这个问题,我们设计了一种利用 MCS-51单片机实现的串并处理转换接口,其接口电路的原理框图如图1所示。由 Tole-do 自动磅秤系统发出的数据以20mA 电流环输 相似文献

In order to improve the adaptiveness of TV/L2-based image denoising algorithm in differ- ent signal-to-noise ratio (SNR) environments, an iterative denoising method with automatic parame- ter selection is proposed. Based upon the close connection between optimization function of denois- ing problem and regularization parameter, an updating model is built to select the regularized param- eter. Both the parameter and the objective function are dynamically updated in alternating minimiza- tion iterations, consequently, it can make the algorithm work in different SNR environments. Mean- while, a strategy for choosing the initial regularization parameter is presented. Considering Morozov discrepancy principle, a convex function with respect to the regularization parameter is modeled. Via the optimization method, it is easy and fast to find the convergence value of parameter, which is suitable for the iterative image denoising algorithm. Comparing with several state-of-the-art algo- rithms, many experiments confirm that the denoising algorithm with the proposed parameter selec- tion is highly effective to evaluate peak signal-to-noise ratio (PSNR) and structural similarity 相似文献
