为解决防洪中水位和降雨量人工监测存在的操作不安全、数据不准确和实时性不强等问题，我们开发了单片机控制的水位与降雨量监测系统。该系统以单片机为控制核心，采用了较好的系统软件与硬件。利用该系统，可实现江河、湖泊与水库水位及降雨量信息的自动采集和处理。关键词：单片机 水位 降雨量 监测Abstract: To solve these question in operate unsafely in data out of truth and in weakliness on scratch for montitor and measuring factitial on waterishline and rainfall in forfend, We have were develop montitor and measuring systems which the singl computers go to control, This systems is a kernel in the singl computers go to control. By use of better hardware and software. We utitized this systems, Will accomplish to gather and dispose automaticly forwaterishline and rainfall in area on river, lago and reservoir.Keywords: Single computers Waterishline Rainfall Monitor and Measuring
