High-voltage electric tower Beidou deformation monitoring and early warning system on unstable slope

Abstract

The invention relates to the geological disaster monitoring field based on Beidou, and especially relates to a high-voltage electric tower Beidou deformation monitoring and early warning system on anunstable slope. The system comprises a slope where a power transmission tower to be measured is located, a geological disaster safety data acquisition Beidou terminal, a local monitoring Beidou terminal and a geological disaster early warning terminal. The geological disaster safety data acquisition Beidou terminal is composed of a power supply device, a high-precision Beidou positioning sensor, alocal deformation data acquisition device and a data processing box. The local deformation data acquisition device is composed of a plurality of resistance-type semiconductor strain gauges. An acquisition device array is arranged on the unstable slope. The geological disaster safety data acquisition Beidou terminal carries out standardization processing on image signals and then transmits information to the local monitoring Beidou terminal through a Beidou satellite. The local monitoring Beidou terminal transmits the information to the geological disaster early warning terminal through judgment, and therefore monitoring and early warning are performed timely before geological disasters happen.

Description

technical field [0001] 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 [0002] Transmission lines are long, geographically distributed, and the environment is complex and diverse. Due to the requirements of the line, when the transmission tower is erected in a mountainous area, affected by gravity, water, and surface subsidence, the slope where the transmission tower is located will have inclination, horizontal displacement, and uneven settlement. If the unstable slope is not given timely warning and reinforcement measures are not taken, it is very easy to cause partial damage or overall collapse of the transmission tower body, thus causing danger. [0003] At present, the detection of high-voltage electric towers is mainly based on the inspection and maintenance of the structure of the electric towers ...

Problems solved by technology

[0002] Transmission lines are long, geographically distributed, and the environment is complex and diverse. Due to the requirements of the line, when the transmission tower is erected in a mountainous area, affected by gravity, water, and surface subsidence, the slope where the transmission tower is located will have inclination, horizontal displacement, and uneven settlement. If the unstable slope is not given timely warning and reinforcement measures, it is very easy to cause partial damage or overall collapse of the transmission tower body, thus causing dangerous situations

[0003] At present, the detection of high-voltage electric towers is mainly based on the inspection and maintenance of the structure of the electric towers by mechanical sensors, and the early warning mechanism for the stability of the slope foundation where the high-voltage electric towers are located is not yet mature, the degree of automation is low, and the early warning cycle time long

Affected by software and hardware, the traditional GPS navigation satellite-based power tower disaster monitoring system mainly deploys GPS positioning acquisition sensors in the area where the transmission tower foundation is located, and can only monitor damage caused by ground subsidence, meteorological disasters, and uneven force on the tower body. The overall inclination and displacement of the foundation caused by the change, the early warning mechanism is inefficient and cannot accurately perceive the mechanical characteristics and trends of geological disasters
