摘　　要：在对煤矿通风机监测过程中,风机的轴温是一个十分重要的参数。对轴温的在线监测可以防止因长时间温度过高导致的烧瓦现象。通过对轴温过高的故障分析,当轴温发生异常时,系统及时报警通知工作人员采取措施。系统采用热电偶测轴温,信号经A/D转换和光电隔离后,经RS485总线输入工业控制机。监测系统采用组态王6.51,构建人机界面和数据采集程序。该系统具有成本低,可靠性高和使用方便等特点。In the monitor of the fan which used in the coal mine,the temperature of the fan＇s axle is a very important parameter. The monitoring on-line can avoid the damage of the bearing liner for long time high temperature.Through analyzing the reason of the fault and making an alarm promptly,the worker can take action on time when there is singularity of the temperature.The system uses thermocouple to measure the temperature and the signal is put into computer after A/D transforming and photoelectricity isolation.The system uses KingView 6.51 to make man-machine interfaces and the programme of data collation.This system has the merits of cheap, trustiness and convenience.
