【正文】 式以實現(xiàn)遠程終端監(jiān)控和報警的功效。傳統(tǒng)的水位檢測系統(tǒng)一般通過有線方式與監(jiān)控中心取得接洽，這種方式不但保護起來艱難，而且在很大水平上限制了其在時空上的拓展性。通過對單片機程序設(shè)計實現(xiàn)對水情監(jiān)測系統(tǒng)的整個水情數(shù)據(jù)的采集、存儲和傳輸程序進行監(jiān)測、判斷和控制以及人機交換。本次設(shè)計以AT89C51芯片為核心，輔以相關(guān)的外圍電路，設(shè)計了以單片機為核心的水情監(jiān)測系統(tǒng)。摘 要我國地處季風氣候區(qū)，暴雨洪水頻發(fā)。系統(tǒng)由12V直流電源供電。關(guān)鍵詞: 單片機 SDI12 數(shù)據(jù)采集 水情監(jiān)測AbstractChina is located in the monsoon climate zone and torrential rain and flood often happens .Affected by this monsoon climate, most of our region is hot wet and more rain in summer .Not only for short duration, high strength local rainstorm often happens, but also rain in wide range of the valley with long duration often happens .Annually, floods disaster happens in large range of our nation with varying degrees. Therefore, Perfect hydrological monitoring can help realtime monitoring hydrological in all regions with the central station and Make timely and reasonable measures for a variety of unexpected situations to prevent disasters and reduce the damage caused by disasters.The design use the AT89C51 chip as the core, bined with the necessary peripheral circuits .We design the hydrological monitoring system with 51 MCU as a core. It consists of 12V DC power supply. On the hardware side, in addition to MCU, It uses SDI12 bus to connect multiple sensors .Collected by TDC40(SDI12 to RS232 converter) the water level sensor data is sent to the MCU ports PO .The MCU use FLASH to store realtime data and transport the collected water level data to the central station through munication channel, such as the PSTN, GSM, COMPASS satellite, maritime satellite and so on. On the software side, we use C language for programming. By programming on the MCU, we realize hydrological monitoring system for the entire hydrological data collection, storage and transport procedures for monitoring, to determine and control and human exchange.Key word: MCU SDI12 data acquisition water level monitoring目 錄第一章 緒言 1第二章 單片機89C51簡介 2第一節(jié) 單片機的特點 2第二節(jié) 單片機89C51介紹 2第三章 基于單片機的水災(zāi)監(jiān)測技術(shù) 4第一節(jié) AT89C51內(nèi)部結(jié)構(gòu) 4第二節(jié) AT89C51引腳及功能 5第三節(jié) 時鐘震蕩電路設(shè)計 7第四節(jié) 電源電路設(shè)計 7第四章 A/D轉(zhuǎn)換器TLC2543 12第一節(jié)TLC2543的編程要點 12第二節(jié) TLC2543與51系列單片機接口 13第三節(jié) 數(shù)據(jù)采集程序設(shè)計 14第五章 系統(tǒng)設(shè)計 16第一節(jié) 系統(tǒng)設(shè)計思路 16第二節(jié) 系統(tǒng)設(shè)計框圖 16第三節(jié) 系統(tǒng)硬件設(shè)計 17第四節(jié) 系統(tǒng)軟件設(shè)計 17
