针对现今煤矿火区存在的测温不准确问题,分析和比较了现今的测温方法,并用工程实例进行验证,最后展望了火区测温方法。结果表明:热电偶在煤矿火区测温效果最好,且应向多点测温方向发展,红外测温仪等无线测温方法的快速性值得重视,光纤测温应该尽快研究。 Aiming at the problem of inaccurate temperature measurement in the fire area of ​​coal mines today, the current temperature measurement methods are analyzed and compared. The project examples are used for verification. Finally, the temperature measurement methods of the fire area are prospected. The results show that the thermocouple has the best temperature measurement performance in the coal mine fire area and should be developed to multi-point temperature measurement. The rapidity of the wireless temperature measurement methods such as infrared thermometer deserves attention. The temperature measurement of optical fiber should be studied as soon as possible.
