摘要: 针对采空区热源温度实时监测、高温点准确定位的难题，利用非接触式红外测温装置研究了采空区模型中高温热源的温度变化规律；分析了热源温度、升温时间、传感器测定温度和测温距离的关系，推导了理想条件下热源定位方程；基于热源温度变化速率的热源温度-时间分段拟合模型和传感器实测温度迭代补偿模型修正了数据的拟合误差和装置的系统误差。结果表明：热源温度随升温时间呈二次函数变化，热源升温速率呈先增大后减小的趋势；传感器测定温度与热源温度成正比，传感器温度接收率与测温距离成反比；修正后的热源温度最大相对误差为0.48%，测温距离平均绝对误差为0.1 m。Abstract: Aiming at the problems of real-time monitoring of the temperature of the heat source in the goaf and accurate positioning of the high-temperature point, the temperature variation law of the high-temperature heat source in the goaf model is studied by using the non-contact infrared temperature measuring device. The relationship between heat source temperature, heating time, temperature measured by sensor and temperature measurement distance is analyzed, and the equation of heat source location under ideal conditions is deduced. Based on the heat source temperature change rate, the heat source temperature time piecewise fitting model and the sensor measured temperature iterative compensation model correct the fitting error of the data and the systematic error of the device. The results show that the temperature of the heat source changes as a quadratic function with the heating time, and the heating rate of the heat source increases first and then decreases; the temperature measured by the sensor is directly proportional to the temperature of the heat source, and the temperature receiving rate of the sensor is inversely proportional to the temperature measurement distance; the maximum relative error of the corrected heat source temperature is 0.48%, and the average absolute error of the temperature measurement distance is 0.1 m.
