介绍了磁传感器和由它组成的磁场测量系统。对磁传感器的非线性、温度误差进行补偿。通过对磁场曲线形状的处理,测量数据误差计算,判断出最大误差点和数值。通过打印机绘图仪输出了磁条的磁场( B) 与长度( L ) 的曲线、磁辊的磁场( B) 与角度(DEG) 的曲线。关键词: 磁传感器; 磁场曲线; 曲线拟合; 误差补偿Abstract : The magnetic sensor and its survey structure are proposed. Non2linear error and temperature error of magnetic sensors are compensated. The max error point and its value are judged by magnetic curve shape and sur2 vey data error. Then the curves of magnetic strips field ( B) with length ( L ) and magnetic roller field( B) with its angle (DEG) are described by printer.Key words : magnetic sensor ; magnetic curve ; curve imitation ; error compensation
