Design Of Transmission Tower Tilt Monitoring System Based On LoRa Wireless Network Communication Technology

With the rapid development of China’s economic construction,the demand for power resources in various industries has been increasing year by year,and transmission lines are an important link in power transmission.Transmission lines rely on transmission towers for support,and the stability of towers is crucial for the safe operation of the power system.The power network in China is widely distributed,covering various geographical environments.Some towers are built in areas where natural disasters may occur,such as forests and steep slopes.When encountering harsh weather,they can cause serious damage to towers and lines,and regional power outages often occur due to tilting and collapsing accidents,seriously affecting social development and people’s normal lives.At present,in some regions of the power grid,the management of transmission tower tilt is still in the manual inspection stage,and the tower monitoring system is not yet perfect,and there is still room for improvement in some aspects.To solve the practical problems of power engineering mentioned above,this paper designs a transmission tower tilt monitoring system,which has completed the following tasks:(1)A "Transmission Tower Tilt Monitoring System" based on LoRa wireless network communication technology was designed to address the issue of monitoring the tilt of transmission towers in existing special terrain environments,after consulting relevant literature at home and abroad.This system has functions such as monitoring tower tilt angle and environmental temperature and humidity,wireless transmission,and early warning.(2)Completed the hardware production of the tilt monitoring system for transmission towers.Using Altium Designer software,the circuit schematic diagrams of sub nodes and terminal nodes were designed,corresponding PCB layouts were drawn,the circuit board was processed,and the required modules were soldered onto the circuit board to complete the hardware design.(3)Complete the software design and implementation of the tilt monitoring system for transmission towers.The data monitoring sub node transmits tilt angle and environmental temperature and humidity data to the terminal node through LoRa.After receiving the data from the sub node,the terminal node transmits all data to the cloud platform through Cat.1.LoRa has advantages such as long transmission distance,fast transmission rate,and low power consumption.At the same time,Cat.1 also has the advantages of wide network coverage,high communication quality,and fast transmission speed.(4)Conduct functional tests on the tilt monitoring system of transmission towers.Place the monitored sub nodes on the simulated tower,connect all nodes to the network,and after the system starts running,the cloud platform can display the tilt angle and environmental temperature and humidity data of the simulated tower in real time.The monitoring accuracy of the tilt angle reaches0.1 °,and the warning function is activated at the same time.The experiment has proven that this system can help staff timely obtain data information of the tower,analyze past data,and timely warn when the tower tilts.This article focuses on practical problems in power engineering and designs a transmission tower tilt monitoring system using LoRa wireless network communication technology.It can achieve real-time monitoring,data transmission,and early warning functions.By simulating tower experiments,various functions of this system are verified,providing assistance for intelligent inspection of power facilities.
