Problems solved by technology

With the application of UAV overhead transmission line channel inspection technology, it is gradually replacing manual foot inspection; however, due to the high cost of UAV overhead transmission line channel inspection, coupled with aviation control, weather and other reasons, UAV channel inspection It can only be carried out 2 to 3 times a year; in this way, during the inspection cycle of the UAV overhead transmission line channel, the monitoring and management of the relative vertical distance of the two crossing overhead transmission lines is out of control, and the power grid security risk is greater

Abstract

The invention discloses a dynamic forecast system and method for a relative vertical distance between two wires. The system comprises a data acquisition module, a model building module, a model updating module and a warning module, wherein the data acquisition module is used for acquiring original data of a to-be-measured wire and an environment where a to-be-measured tree is located, the model building module is used for building a three-dimensional model of the to-be-measured wire and the to-be-measured tree according to the original data, the model updating module is used for updating the three-dimensional model in real time according to changes of the environment and time, the warning module is used for monitoring a clearance distance between the to-be-measured wire and the to-be-measured tree in the updated three-dimensional model in real time and giving out warning information when the clearance distance is smaller than or equal to a preset range. A passage of an overhead power transmission line is monitored by the three-dimensional model, the clearance distance can be forecasted in real time, the warning information is give out when the clearance distance is smaller than orequal to the preset range, timely handling is performed, and the problem of safety of a power grid is prevented; and the passage inspection period of an unmanned aerial vehicle overhead power transmission line can be saved at least by nine or ten times, and the social benefit and the economic benefit are very remarkable.

Description

technical field [0001] The invention relates to the technical field of distance measurement, in particular to a dynamic prediction system and method for the relative vertical distance between two wires. Background technique [0002] The inspection of the traditional overhead transmission line channel mainly relies on manual inspection on foot. With the application of UAV overhead transmission line channel inspection technology, it is gradually replacing manual foot inspection; however, due to the high cost of UAV overhead transmission line channel inspection, coupled with aviation control, weather and other reasons, UAV channel inspection It can only be carried out 2 to 3 times a year; in this way, during the inspection period of the UAV overhead transmission line channel, the monitoring and management of the relative vertical distance of the two intersecting overhead transmission lines is out of control, and the security risk of the power grid is relatively large.
