Description

A monitoring and early warning system for Beidou deformation of high-voltage electrical towers on unstable slopes

technical field

The invention relates to the field of geological disaster safety monitoring, in particular to a high-voltage electric tower Beidou deformation monitoring and early warning system on an unstable slope.

Background technique

Transmission lines have long lines, wide geographical distribution, and complex and diverse environments. Due to line requirements, when transmission towers are erected in mountainous areas, affected by gravity, water, and surface subsidence, the slopes where the transmission towers are located will be inclined, horizontally displaced, and unevenly settled. If there is no timely warning and reinforcement measures on the unstable slope, it is very easy to cause local damage or overall collapse of the transmission tower body, which will lead to dangerous situations.

At present, the detection of high-voltage towers is mainly based on the inspection and maintenance of the tower structure based on mechanical sensors, while the early warning mechanism for the stability of the slope foundation where the high-voltage towers are located is not mature, the degree of automation is low, and the early warning cycle time long. Affected by software and hardware, the traditional tower disaster monitoring system based on GPS navigation satellites mainly deploys GPS positioning acquisition sensors in the area where the transmission tower foundation is located. The overall inclination and displacement of the foundation caused by the change, the early warning mechanism is inefficient, and the mechanical characteristics and trends of geological disasters cannot be accurately perceived.

In view of the above-mentioned defects in the prior art, we have invented a high-voltage tower Beidou deformation monitoring and early warning system on an unstable slope, which is simple in layout, convenient in operation and has obvious warning effect. On the one hand, the local deformation data acquisition device of this system can sense the local mechanical changes and deformation trends of the electric tower foundation slope in real time with the help of resistive semiconductor strain gauges arrayed on the slope; on the other hand, this system is based on the Beidou high-precision spatial positioning technology. , with the help of Beidou high-precision spatial position sensor and Beidou positioning reference point sensor, through the solution algorithm server solution, it is possible to achieve high-precision real-time monitoring of the overall deformation of the slope foundation where the tower is located.
