摘 要
在水资源利用方面，对流量、水质等参数的测量非常重要，但很多水库资源在高山地区，难以对其进行实时监测。无线通讯技术的迅速发展和普及，为远程监控系统的实现提供了理想的平台，因此越来越多的水文站把基于无线通讯技术的监控系统作为水利系统自动化管理的新手段。而随着水利自动化技术不断发展，水利系统的自动化水平逐步提高，各水库都能通过远程监控系统逐渐实现少人、无人监管的管理模式，以提高生产效益。
本文主要探讨了基于无线通讯的模拟水库监测系统的设计问题。该系统要求对水库的水位，流量等参数进行远程实时监测，能控制阀门开/关，调节水位的高度，保证水库的安全。设计思路是在下位端利用单片机将传感器采集的水库信息进行处理，将处理好的数据通过CC1100无线模块传送到上位机端，在上位机上可以清楚地观察水库的实时情况。上位机对信息进行监测分析，并将分析后的信息反馈回到下位端，通过单片机控制步进电机正反转，模拟阀门开/关，来控制水库水位和流量，保证水库的安全。近年来，本课题在国内外已受到非常多的关注与研究，并且不断地得到改进，在实际应用中也取到了较好的效果，具有非常好的应用推广价值。

Abstract
In water resources utilization, the measurement of parameters such as the rainfall, flow, water quality,etc. These are very important, but a lot of reservoir resources are in the alpine areas, it is difficult to monitor it in real time. Rapid development and popularization of wireless communication technology, which have offered the ideal platform for realization of the long-range monitoring system, so more and more hydrometric stations regard monitoring system based on wireless communication technology as the systematic automatic management new means of water conservancy. And as the automatic technology of water conservancy is being developed constantly, the automatic level of the water conservancy system is being improved progressively, every reservoir can realize the management mode that few people, nobody supervises gradually through the long-range monitoring system, in order to improve the productivity effect.
This text has mainly probed into the design question based on simulation reservoir monitoring system of the wireless communication. This system requires the water level to the reservoir, the flow is monitored when the parameter is carried on long-range and really, can control valve turn on or off，height to regulate water level, security to guarantee reservoir. Mentality of designing to utilize one-chip computer go on, dealing with reservoir information that transducer gather in the next end, it is ones that handle well data until CC1100 convey to modules wireless for location machine, in location can situations real-time to observe reservoir clearly. Go location plane go on, monitor, analyzed to information and information feedback analyze, got back to the next end, control, and walk into electrical machinery to be positive and negative to look around through one-chip computer, simulation valve turn on or off, controlling reservoir water level and flow, guarantee the security of the reservoir. In recent years, subject this pay close attention to the fact and study a very many one already at home and abroad, and is being improved constantly, fetch in practical application to better result, having very good application value to popularize.
