摘　　要：介绍了一种由MEMS传感器与32位Crotex-M0微处理器LPC114组合设计而成的输电杆塔倾摆安全监测仪,将MEMS加速度计输出的数字信号与陀螺仪的数据进行卡尔曼滤波,解算出倾角度数,通过GPRS传输到远程服务器上。该设备体积小、功耗低、处理速度快,可采用太阳电池供电,可应用于电力、通信、桥梁等重力参考系下的杆塔倾摆实时监测。A tilting measuement instrument is introduced. It is designed by the combination of MEMS sensors and LPC1114 which is 32-bit Crotex-M0 microprocessor on the market. The digital signal output of MEMS ac- celerometer and gyroscope is processed by Kalman filtering. Then the inclination angle in degrees is calculat- ed. Finally, the data is transmitted to a remote server. The instrument has a small size, low power consumption, fast signal processing speed, and can use solar green energy. Then, it can be widely used in the tower tilting re- al-time monitoring of electricity, communicetion, bridges and gravity reference system.
