摘　　要：本文研制了一种用于起重机底座转盘水平状态监测的新型水平传感器,该传感器采用双轴加速度芯片SCA100T作为敏感元件,结合数字信号处理、单片机技术和LCD显示技术,将起重机底座转盘与水平面的夹角以数字的形式直接显示在LCD显示器上。实验数据分析表明,该水平传感器最大误差小于0.015°,满足起重机底座转盘水平状态的监测要求。A new level sensor system is developed for monitoring the horizontality of crane rotary base. The system utilizes the dual-axis accelerometer SCA100T as sensitive element, integrates some new technologies such as digital signal processing, microcontroller and LCD display , and shows the angle between the crane rotary base and the horizontal plane on the LCD player in digital form. Experimental results show that the maximum error of the sensor system is less than 0.015°. So it can meet the requirements of monitoring the horizontality of crane rotary base.
