| Transmission towers are an important part of transmission lines.Because of the geographical and meteorological environment,it is easy to cause abnormal conditions such as tilting and shaking of transmission towers,which will seriously cause deformation and collapse of transmission towers and affect the normal operation of transmission lines.At present,the abnormal state survey of transmission towers is still at the stage of regular line inspection and visual inspection by inspection personnel.The manual inspection method not only has a large demand for manpower and material resources,but also lacks an effective and accurate measurement of the tower tilt.As well as the method of predicting the slope change trend,the shaking of the transmission tower caused by external factors has certain uncertainty and suddenness,and it is difficult to find it in time by manual regular inspections.There is an urgent need to design a system capable of long-term,real-time monitoring of transmission tower tilt and sloshing.Through real-time monitoring of transmission tower tilt and sloshing,early detection of faults can be achieved,accidents can be avoided,and power system safety can be improved.,Stable operation,while also greatly reducing the number of manual inspections and work intensity.This paper first analyzes and researches existing domestic and foreign online monitoring devices for transmission equipment,and designs a wireless monitoring system for transmission tower tilt and slosh,which is used to monitor the slope,slosh,and surrounding weather information of the transmission tower in real time.An alarm is issued for abnormal conditions.The wireless monitoring system for transmission tower tilt and sloshing specifically includes data acquisition,data processing,wireless communication,and remote monitoring software.In the data collection part,the status of the tilt and sway of the transmission tower is monitored by the MPU6050 sensor;the temperature,humidity,wind speed,and wind direction information are monitored by the temperature and humidity sensor,wind speed sensor,and wind direction sensor.In the data processing part,the monitoring equipment uses a low-power consumption micro-control chip STM32L496VGT6,reads the data collected by each sensor through the serial port,and sends the read data to the wireless communication module.In the wireless communication part,the data collected on-site is sent to the remote monitoring software through the Internet through the 4G wireless communication module to realize the long-distance transmission of the data.In the remote monitoring software part,the remote monitoring software uses Python for development and design,receives the collected data sent by the 4G wireless communication module through the Internet,processes and stores the received data,and then uses the image to visually display the status of the tower. |
