论文题目：煤矿安全监控系统井下监控分站设计（软件）专业：电气工程及其自动化本科生：（签名）指导老师：（签名）摘要煤炭是我们国家发展最主要的能源，同时我们国家也是当今世界上最大的煤炭生产国之一，所以煤炭的安全生产就显得尤为重要，而在这过程中，煤矿的安全监控系统就是煤矿安全生产的最重要的保障。本论文主要研究设计的煤矿井下安全监控分站是煤矿安全监控系统的主要设备之一。该分站主要包括数据输入通道、控制输出通道、键盘操作和液晶显示模块。本设计采用STC89C52单片机作为控制器。单片机对输入通道采集的开关量和模拟量信息进行分析处理后，经输出通道控制执行器动作。当输入信号超过预设定的报警值或断电动作值时，进行声光报警或断电处理。键盘操作和液晶显示则可以实现人机交互。这样就可以构成一个典型集中管理分散控制系统。最后，通过实验验证所设计的分站可以实现数据采集、风电瓦斯闭锁、键盘操作和液晶显示等功能，从而实现实时监测与控制，满足煤矿井下井下安全生产的要求。关键词：监测监控系统，监控分站，闭锁，安全Subject:UndergroundMonitoringSub-stationofCoalMineSafetyMonitoringSystemDesign(software)Specialty:ElectricalengineeringandautomationName:(Signature)Instructor:(Signature)ABSTRACTCoalisthemajorenergyofourcountry,andourcountryisoneoftheworld'slargestproducersofcoal,therefore,thesafetyofcoalproductionisparticularlyimportant,inthisprocess,thecoalminesafetymonitoringsystemisthemostimportantsafeguards.Thisthesismainlytalkabouttheundergroundmonitoringsub-stationwhichisoneofthemainequipmentofcoalminesafetymonitoringsystem.Itincludesdatainputchannel,outputchannel,keyboardandLCDdisplay.ThisdesignusesSTC89C52SCMasthecontroller.SCManalyzesandprocessesdigitalandanaloginformationacquiredbyinputchannel,andthencontrolactuatormovementthroughtheoutputchannel.Whentheinputinformationexceedsapresetalarmvalueorpoweractionvalue,soundalarmingorpowerhandling.KeyboardandLCDareanimportantpartofhuman-computerinteraction.Thiscanconstituteatypicalcentralizedmanagementanddecentralizedcontrolsystem.Finally,theexperimentalverificationofthedesignedsub-stationcanrealizedataacquisition,controloutputwindpowergaslocking,keyboardandLCDdisplayandsoon,Achievingreal-timemonitoringandcontrolandmeetingsafetyrequirementsofundergroundcoalmineproduction.KEYWORDS：monitoringsystem,monitoringsub-station,gaslocking,safety目录1绪论..........................................................11.1矿山安全监控系统的发展历程.........................................11.1.1国内煤矿安全监控系统的发展...................................11.1.2国外煤矿安全监控系统的发展...................................11.2课题研究意义.......................................................21.3论文的主要工作及结构安排...........................................21.3.1论文的主要内容...............................................21.3.2论文的结构安排...............................................31．4本章小结..........................................................32煤矿井下监控分站设计的总体方案................................42．1矿井监控系统的组成................................................42.1.1监控主机.....................................................42.1.2传感器.......................................................42.1.3井下分站.....................................................52.2井下监控分站系统设计目标...........................................62.3井下监控分站的总体设计.............................................62.3.1系统总体功能架构综述.........................................62.3.2系统结构框图设计.............................................72.4小结...............................................................73煤矿井下监控分站的硬件设计....................................93.1井下监控分站设计的主要技术参数.....................................93.2井下监控分站硬件模块设计......................................103.2.1主控制电路..................................................103.2.2电源模块....................................................123.2.2传感器开关量输入通道模块....................................143.2.3模拟量压频转换模块..........................................153.2.4控制输出模块................................................153.2.5拨码地址模块................................................163.2.6声音报警模块................................................173.2.7按键控制模块................................................173.2.8液晶显示电路................................................183.3本章小结..........................................................184煤矿井下监控分站的软件设计...................................194.1软件设计平台......................................................194.2井下监控分站主程序的设计........................................194.2.1控制器相关简介..............................................194.2.2主程序流程..................................................214.3井下监控分站模块子程序设计........................................224.3.1传感器数据采集..............................................224.3.2显示主程序..................................................244.3.3输出控制程序................................................254.3.4拨码开关程序设计............................................284.4本章小结..........................................................285井下监控分站的调试及运行结果.................................295.1井下监控分站硬件电路测试..........................................295.2井下监控分站系统调试..............................................305.3本章小结..........................................................316结论与展望...................................................326.1结论..............................................................326.2展望..............................................................32致谢..........................................错误!未定义书签。参考文献.......................................................34附录...........................................................35附录一：系统电气原理图................................................35附录二：井下监控分站软件
