摘    要
      矿井主通风机是煤矿生产的关键性设备，其可靠性及安全性直接关系到矿井生产的正常化及煤矿工人的人身安全。随着中国煤炭工业的不断发展，国家对安全生产治理力度的加大，煤矿企业对矿井通风设备提出了更高的要求。
本文以AGF606—1.881.12风机为例，介绍采用PC机与可编程序控制器为核心的煤矿主扇风机监控系统（重点为上位机）的设计、特点及性能。该系统既可实时准确检测、控制与保护主扇风机运行,又提高了矿井现代化管理水平。
在矿井主通风机性能在线监测中，介绍了利用的WinCC组态软件,设计一套自动采集、处理、显示数据和性能曲线绘制,并且可以实现风机控制的系统。整个系统具有界面友好、操作方便、功能齐全等优点。
本课题设计的通风机性能监测系统，是在基于现行的各种通风机监测方法，并结合先进的测试技术而设计的。该系统以计算机为核心，选用了适合通风机运行环境的硬件，采用了WinCC组态软件，来实现通风机性能在线实时监测。在监测的基础上，还可以根据需要绘制出通风机的性能曲线和打印测试数据报表。在研制的过程中，采用了“软件即硬件”的思想，使监测系统的成本极大的降低。

ABSTRACT
The coal mine main fan is the coal mine production crucialequipment, its reliability and safety is directly related to the normalization of mine production normalized and coal miner's personal safety. Along with the China coal industry unceasing development, the country to safety in production government dynamics enlarging, the coal mine enterpriseset a higher request to mine ventilation equipment.
AGF606—1.88—1.12 axial ventilator as all example is used，the designing,characteristic and performance of monitoring and control system (The key is on  super-computer)for coal mine main fan is introduced in the paper,in which in PC computer and programmable con-troller are utilized as the core.The system can implement real-time accurate detection,control and protection for operation of main fan and improve mine modernization management.
The application of WinCC for SCADA software in coal mine main_fan’s function on_line monitoring is introduced.The system that has automatic data collection,manage-ment,display and performance curve plotted,accom-plishes the adjustment of fan control is designed. The system integrated sensor technology, computer technology and measurement technology.
The project is aimed at studying monitor system of farmer's performance.Basing on combining all actual monitor means of farmer with advanced testingtechnique, the project succeeds in computer monitor system of the farmer's performance.The system depends on computer as well as electing suitable hardware of farmer's performance and adopting WinCC for SCADA software, can realize on line real time monitor of farmer's performance. Using the monitor data,the system also can draws performance's curve of farmer and print report forms of testing data under demands of users. Due to adopting "software namely hardware" in the course of the development, the cost of the monitor system greatly reduce.
