Research on the Recognition Method of Electric Energy Meter Lead Title based on the Fuzzy Image Processing

This article puts forward an automatic recognition algorithm of electric energy meter lead seals： firstly, the image will be histogram equalization, smoothing, binaryzation pretreatment, then according to the image characteristics of text changes, the system can quickly and accurately segment image from complex background, finally the system extract different dimension and the feature of English and Arabia using digital projection transform coefficient method and to identify the corresponding number by BP neural network, solves the problem of automatic recognition of electric energy meter lead sealing.

密封铅酸蓄电池的现状与发展(Ⅰ)

1 前言 自1859年法国普兰德发明了实用的铅酸蓄电池以来,铅酸蓄电池虽历经变革,电池性能不断得到改进,但电解液呈流动型,仍万变不离其宗。由之决定了铅酸蓄电池容易漏酸、过充时大量析气并须不时地添液加水、调整电解液比重等固有的弊端,给电池使用上带来很大的不便,亦限制了电池的应用范围。1957年德国阳光公司和1971年美国的盖茨公司分别推出电解液不流动的、不溢液、不冒酸雾,不须添液加水。
