摘　　要：为了实现对煤炭地下气化中各种参数的实时监控与数据分析,准确的实现对生产过程中各个关键变量的控制,本文设计了基于PLC的煤炭地下气化过程测控系统,本文首先介绍了地下气化的工艺流程和检测需求分析,其次对总体方案和软硬件进行设计,最后对数据库以及应用到的数学模型进行简单的介绍,测控系统由三层拓扑结构构成:设备层、控制层、监控层.设备层包括基本的硬件设备;控制层包括两个西门子S7-300系列PLC站,构成双CPU软冗余系统,保证当其中一个PLC站出现故障时可保障点火巷的稳定送风;而监控层使用组态王和Navicat Premium等软件,实现了对数据实时监控显示、视频画面实时监控显示、历史数据存储等工作.此项目已经成功在隶属于贵州盘江精煤股份有限公司的山脚树矿成功运行近一年时间.In order to achieve the various parameters in the process of underground coal gasification of real-time monitoring, data analysis, and the realization of accurate control of the production process of all key variables, this study designs the underground coal gasification process measurement and control system based on PLC. This paper first introduces the underground gasification process and testing requirements analysis, secondly presents the design of overall scheme and hardware and software, finally elaborates the database and mathematical model used in the applications. The mathematical model of measurement and control system consists of three layers of topology： device layer, control layer,and monitoring layer. The equipment layer includes the basic hardware devices. The control layer includes two Siemens S7-300 series PLC station, constituting the double CPU soft redundancy system, to ensure the stable air supply in ignition lane when one PLC station fails. Monitoring layer uses the configuration KingView and Navicat Premium software.Above design realizes the real-time monitoring of data display, video image real-time monitoring, historical data storage,and so on. This project has been successful run for nearly a year in Shanjiaoshu Mine affiliated with Guizhou Panjiang Reined Coal C0.Ltd..
