新型电力架空线路杆塔倾斜在线监测装置OA

To overcome the shortcomings of the existing means of monitoring the tilt of power overhead line towers,such as large monitoring blind area,low degree of Internet of Things,poor monitoring accuracy and susceptibility to interference,a new on-line monitoring device for the tilt of overhead line towers is designed.The proposed device takes STM32L422KBT6 low-power processor as the control core,uses 16-bit six-axis acceleration sensor to calculate the tilt angle of the tower,adopts Kalman filtering algorithm to digitally process the sampled values to obtain better accuracy,and connects with the cloud server by means of 4G wireless communication to realize the real-time uploading and displaying of the collected data and alarm informa-tion,as well as the remote control of the monitoring device.The experimental test results show that the proposed device's tilt measurement error is less than 0.15°,and has stable communication,low power consumption,and provides a low-cost,high-stability means of tower tilt online monitoring for the Internet of Things.
