摘要
水塔远程供水自动控制
学生： 指导教师：
[摘 要] 在信息化迅速发展的今天，我国许多地区水塔供水系统的硬件设施和软件技术落后，在水井距离用水点较远的场合，通常需要水塔来供应生产、生活用水，然而，人工启动水泵的上水效率低，而且难以把握水位，而国内一般的解决方案是用电台在水塔和泵房之间通信，但电台信号容易受到高压线、变电站等强电磁信号的干扰，如何方便、快捷的实现管理者与水塔之间的自动控制，是目前所需要解决的关键问题。本课设计实现了一个基于SMS短消息的单片机控制系统，采用模块化设计方法，编写了水位检测、短信远程控制、继电器水泵控制三个模块，利用水位检测系统自动控制水塔内的液面高度，最终以短消息的形式发送给管理者，从而实现水塔的远程自动控制。

Abstract: With the rapid development of science and technology, in zip code, statistics, reports, financial statements, Bank bills dealing with a large number of characters, such as information recorded occasions, handwritten digit recognition system of requirement has become stronger and stronger, how easily and quickly the number entered in the computer has become a key issue relates to the popularization of computer technology. This article design implementation has a based on Matlab software of handwriting body digital recognition system, used module of design method, write has camera entered, and directly read pictures, and write Board entered three a module, using camera, tools, will to text form exists of handwriting body digital entered into computer, completed on handwriting body digital pictures of collection, and design has a handwriting digital recognition method, on handwriting body digital image for pretreatment, and structure features extraction, and classification recognition, eventually to text form output digital, to implementation handwriting body digital of recognition.
Key words: Pretreatment, structure feature extraction, classification and recognition, handwritten digit recognition.
