输电线路杆塔倾斜是处于不良地质区（采空区、滑坡区、高盐冻土区等）的输电线路随时会出现的严重故障，为了及时发现杆塔倾斜并修复，需要对杆塔的状态进行实时监测。依据重力加速度测量值计算倾斜角原理，设计开发了一种输电线路杆塔倾斜检测装置，采用基于微机电系统的三轴加速度计ADXL345作为传感元件进行数据采集，采用含有无线射频电路及Zigbee协议栈的STM32W108片上系统作为中央处理器进行加速度采样数据处理，并经Zigbee网络传送至上位机，实现了杆塔倾斜角的实时检测。

Tilt of transmission line tower is a serious failure of transmission lines in poor geological zones (the hidden cavity, landslide areas,high salt permafrost zones etc.). In order to detect and fix the tower tilt,the status of tower should be monitored in real time. According to the inclination calculating principle based on the gravity acceleration measurements, a transmission line tower tilt detection device is designed and developed. In the device,ADXL345 (a accelerometer of three-axis sensing element based on MEMS)is used for acquisition of acceleration caused by gravity. The STM32W108(a system on chip with the Zigbee protocol stack embeded)is used to process the acceleration sampled data. The inclination is sent back to the monitoring center via Zigbee network in order to monitor the tower status in real time.
