水位遥测自控系统设计水位遥测自控系统[摘要]本系统以51单片机系列的STC12C5406AD单片机为主控单元，通过液压传感器和无线通信实现液位实时数据的检测和自动控制。系统分主控站与测控站，通过主控站的键盘可以实现对测控站的水位上下限的控制和显示。主控站与测控站之间的无线实时数据传输的解决方案采用广泛应用于无线通信的SMD技术。从测控站传送过来的数据通过人性化人机交换界面LED显示器件实现数据的实时数据显示。本系统通过单片机串口与电脑串口的通讯功能和利用互联网可以实现对水库水量的远程测量与自动控制，这对江河水位的实时监控非常实用。系统利用功能强大的C语言开发，并在软硬件设计中分别使用了Protel99se、keilC51开发平台。结果表明，该系统具有有性价比高、操作简便、可视化操作等优点.[关键字]：51单片机，TDL9912，TDL9921，声表谐振器[Abstract]：Thissystem51microcontrollerfamilySTC12C5406ADSCMasmaincontrolunit,throughthehydraulicliquidlevelsensorsandwirelesscommunicationstoachievereal-timedetectionandautomaticcontrol.Thesub-masterstationsandmonitoringstations,throughthemastercontrolstation'skeyboardcanbeachievedonthewaterlevelmonitoringstationsoftheupperandlowerlimitsofthecontrolanddisplay.Masterstationandthemonitoringandcontrolstationsofthewirelessreal-timedatatransmissionsolutionsarewidelyusedinwirelesscommunicationsSMDtechnology.Comefromthemonitoringstationtosendthedatathroughuser-friendlyman-machineinterfaceforLEDdisplaydevicestoexchangedatainreal-timedatadisplay.Thesystem,throughthemicrocontrollerserialportserialcommunicationwithcomputerfunctionsanduseoftheInternetcanbeachievedontheremotereservoirwatermeasurementandautomaticcontrol,thisreal-timemonitoringofriverwaterlevelisveryuseful.SystemusesapowerfulClanguagedevelopment,andseparatelyinthesoftwareandhardwaredesignusingProtel99se,keilC51developmentplatform.Theresultsshowthatthesystemhasacost-effective,easytooperate,visualizeandsoon.[Keywords]:51MCU,TDL9912,TDL9921,SAWresonators目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc251665146"1绪论PAGEREF_Toc251665146\h3HYPERLINK\l"_Toc251665147"1.1选题背景与意义PAGEREF_Toc251665147\h3HYPERLINK\l"_Toc251665148"1.2课题介绍PAGEREF_Toc251665148\h4HYPERLINK\l"_Toc251665149"1.3MCS-51单片机简介PAGEREF_Toc251665149\h4HYPERLINK\l"_Toc251665150"1.3.1单片机的雏形PAGEREF_Toc251665150\h4HYPERLINK\l"_Toc251665151"1.3.2单片机的发展PAGEREF_Toc251665151\h5HYPERLINK\l"_Toc251665152"1.3.3单片机最小系统PAGEREF_Toc2
