Description

Technical Field

[0001] The utility model relates to the field of power system operation monitoring, in particular to a geological disaster prediction data acquisition device based on transmission line tower monitoring. Background Art

[0002] Transmission lines are long, and projects often cross different topographical and geomorphic units, regional geological structural units, hydrogeological units, engineering geological units, and mining areas. The site selection and design of pole towers are limited by the depth of preliminary investigation and construction and transportation conditions. Some of them may be very close to the disaster site or have been on the geological disaster surface due to human activities in recent years. For transmission lines, geological disasters that are prone to occur due to special topographic and geological conditions mainly include small landslides, collapses, collapse of goaf areas, ground fissures, etc., which have the distinctive characteristics of long development time, unclear process, strong suddenness, great destructiveness, and difficult prevention and control. The direct harm is that the pole tower collapses and causes grounding accidents or line breaks, which causes significant losses to the power grid and the national economy. Therefore, it is very important to predict possible geological disasters through daily monitoring of the operation of transmission line pole towers. At present, the daily monitoring of the operation of transmission line towers generally uses handheld monitoring instruments. The handheld monitoring instruments can measure the inclination of the towers from time to time, but it is impossible to achieve real-time and accurate data collection of displacement, so it is impossible to predict geological disasters. Moreover, the data obtained are all post-incident data, and it is impossible to monitor and predict the operation status of the towers in real time. Some poles are also equipped with satellite positioning systems, but they cannot monitor deformation factors and accurately locate small displacements. In addition, the hardware cost of the previous positioning system is high and the power consumption is large, which is not conducive to large-scale promotion. In addition, the data type obtained in the process of monitoring transmission line towers is relatively single, so it cannot meet the user's subsequent needs for accurate prediction of geological disasters.
