基于最小二乘法的风速传感器测量值推导巷道平均风速
|
摘要
对比分析了同一时间风速传感器的测量值和实测的平均风速值;研究了传感器测量数据和人工实测数据之间的数量关系;对风速传感器的测量数据采用最小二乘法进行拟合处理,获得井下各工作地点风速传感器的测量值和平均风速之间的曲线图,并拟合出关系式,根据得到的关系式将风速传感器的测量数据转化成平均风速,将转化得到的平均风速直接应用在井下通风系统的日常管理和优化改造中。
Compared with sensors measured values and actual measured average wind speed values,the quantitative relation of monitoring system data and measured data was analyzed and studied.Based on least square method,the fitting of wind speed sensors measured data was conducted,the curve graph of sensor measured value and average wind speed value of each workplace was made,and solved fitting relational expression,measuring data of monitoring system were transformed into average wind speed value by making use of relational expression,and correctional data were applied directly to manage and optimize ventilation system.
