毕业设计_基于单片机的水位监控系统设计.pdf

中 文 摘 要 摘 要 水资源已成为中国当前和未来发展重要资源，因此对水资源的合理利用 有重要意义。在我国很多地方都需要水位监测，如工厂蓄水池、农田灌溉用的 水库、江河水位等等，因此利用现代化的通信手段对水资源进行测控以及使用 计算机管理系统来实现对水位监测点现场水位等数据的采集与监测，并可在水 位信息管理平台上进行水位数据的存储、显示、查询等，将是对水资源实现科 学管理的一个重要手段。本文从经济性和可靠性出发，在实验的基础上，设计 了一种能够实现水位自动控制的装置。 单片机技术的测控系统以其体积小，可靠性高而被广泛采用。本文对该测 控系统进行了分析设计。首先，设计针对系统所使用的单片机的性能和发展情 况做了简单介绍；对超声波传感器的原理做了简单分析，对系统使用的模 / 数转 换芯片 ADC0809也做了性能方面的简单说明。 其次，论文重点对测控硬件、软件的组成进行了分项、模块化逐步分析设 计。对各部分的电路一一进行了介绍，最终实现了该系统的硬件电路。绘制了 电路原理图。 关键词： 单片机、 ADC0809 、软件系统、硬件系统 - 1 - 中 文 摘 要 Abstract The water resources has become Chinas current and future development of the important resource,It has important significance for the rational utilization of water resources. In many places of our country need to water level monitoring, such as plant reservoir, reservoirs, irrigation water level and so on, therefore the use of modern means of communication to measure and control the water resources as well as the use of computer management system to realize the acquisition and monitoring of data level monitoring in field level, and water level data storage, in the water level information management platform display, query and so on, is an important means to realize the scientific management of water resources. This paper from the economic and reliability point of view, on the basis of experiment, a device which can realize automatic water level control is designed. Control system of single chip microcomputer technology with its small size, high reliability and is widely used in. The paper analyzes the design of the measurement and control system. First of all, the performance and the development of the design used in the single chip microcomputer is introduced b
