Hundreds of features extracted from object images need to be detected and every feature need to be evaluated by its threshold in AOI system. In order to cope with the study problem of multi-parameters thresholds during the solder joint surface qualify inspection in AOI system, a self-adaptive study method is proposed in this manuscript. Firstly, solder joint features are extracted from the solder...
The functions of the available network fault management system are imperfect, with relatively poor comprehensiveness, flexibility and intelligence. This paper designs the dynamic distributed architecture of network fault management system, evenly assigning fault management tasks to each domain manager by BP neural network algorithm. In order to intelligently diagnose the fault events as quickly as...
At present, the registration algorithms based on the rigidity medical image are developed and also used well in actual clinical. But the non-rigid medical image registration algorithms are still developing, therefore domestic and foreign researchers put forward various non-rigid registration algorithms. Firstly, this paper analyses the necessity of non-rigid registration. Secondly, specifies the recent...
A cause analysis model of pseudo solder for chip component is presented. Based on analyzing the causes of the chip pseudo solder, an comprehensive equation, which is composed of an ellipse equation and a circle equation, is used to fit the surface shape of chip solder joint. On the basis of that, the chip pseudo solder model is presented. All the parameters of the chip pseudo solder model are effected...
This paper carried out the research on Pu'er fermentation automatic control process, using engineering and biotechnology and the application of parameters in the critical link of Pu'er tea quality formation. Pu'er tea fermentation plant design were optimized; the tide proportion before Pu'er tea fermentation had been carried out accurate quantitative and automatic control study; the temperature and...
This article introduces SIMTIC S7-300 programmable controller and configuration software WINCC6.0 of German Siemens, and the application in the Pu-Er Tea automated fermentation system. The system contains the upper computer and the lower computer. The upper computer is composed of PC and configuration software WINCC6.0.The lower computer is composed of PLC S7-300. Appling the system to Pu-Er Tea fermentation...
