The complexity and diversity of the geological environment, especially in the high mountainous and hilly areas, are often accompanied by natural disasters such as landslides, mudslides, avalanches and ground subsidence/subsidence, which seriously threaten the safety of people's lives and property. Meanwhile, with the rapid development of infrastructure construction in China, such as reservoirs, dams, bridges, pylons, high-rise buildings and so on, there is a large number of emergence.
In particular, transmission line towers, when facing multiple challenges such as wind load, tower line tension, and geological subsidence, fall tower accidents occur frequently, posing a major threat to power grid safety. Therefore, realizing long-term effective monitoring of the geology around transmission line towers and early warning of potential dangers has become a key issue to be solved urgently.
Shenzhen Dingxin Wisdom Technology's Transmission tower radar deformation Online monitoring system is developed to solve this problem. The device uses interferometric technology to measure the displacement change of the target through the phase difference of the radar reflection wave, without touching the ground, it can complete the monitoring of the dangerous area. This technology is not only mature and reliable, and has ultra-high precision, theoretically small recognizable displacement changes of 0.000000068mm, fully meet the monitoring needs of bridges, buildings, towers, slopes and other industries,.
During the operation of transmission towers, the transmission tower radar deformation online monitoring system can accurately analyze the vibration situation of the target object from 0 to 50Hz, get the multi-order vibration frequency of the target object, intelligently judge the safety status of the tower through the collection of the vibration parameters of the base of the tower as well as the wind vibration strength of the guide wire, as well as the algorithm processing and analysis of the background algorithm in the back-end of the transmission system main station, the storage of the data, the data modeling and other functions. , providing scientific basis for decision-making. At the same time, data encryption to protect the confidentiality and integrity of the data, support access to the power grid unified platform, to achieve data interoperability, relevant personnel can log in the computer terminal or cell phone client with different permissions, at any time to access the site tower safety data and safety assessment information.
In addition, based on interferometric technology, the radar deformation online monitoring system for transmission towers can realize long-distance, high-precision 24-hour all-weather displacement monitoring without the need to install sensors in the target area. For a long time, our radar deformation online monitoring system has been widely used in transmission tower monitoring, outdoor bridges/dams and other infrastructure monitoring, as well as geologic disaster monitoring, and has received good feedback!
