Precision navigation substation patrol inspection UAV system

Abstract

The invention discloses a precision navigation substation patrol inspection UAV system, which comprises a UAV take-off and landing platform, a UAV body, a ground monitoring and control system, and a flight route generating system, wherein the UAV take-off and landing platform comprises an attitude control module, a wireless transceiving module, a flight return module and a charging pipe; the UAV body is provided with a flight control system, an obstacle avoidance sensor, an attitude sensor, a navigation and positioning system, a UAV power system, a wireless transceiving module and an airborne holder; a battery voltage alarm module is electrically connected with the UAV power system; the ground monitoring and control system comprises a ground video monitoring module, a camera-shooting angle control module, a flight control module, a storage module, an alarm module, a wireless transceiving module and a control computer; and the flight route generating system comprises a GPS positioning matrix simulation module and an analog positioning signal transmitting antenna. Through integrating the obstacle avoidance function, fixed-height hovering technology and the like of the UAV, the precision navigation substation patrol inspection UAV system meets the requirements of flying in narrow space environments such as a substation and executing patrol inspection task.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle inspection, in particular to an accurate navigation substation inspection unmanned aerial vehicle system. Background technique [0002] At present, foreign countries have only implemented partial research on UAVs, and have not applied them to substation inspections to realize intelligent management of substations. However, domestic research on the application of UAVs is limited to inspections of transmission lines, and has not been applied in substations. [0003] In the existing technology, UAVs rely on GPS or Beidou navigation and positioning system for positioning and navigation, while the precision error of conventional navigation systems is within 2 meters. , indoors and other places with narrow spaces and weak signals to carry out fixed-point or autonomously planned path inspections, the current dedicated technologies that are stably implemented in the industry have not come in handy....

[0002] At present, foreign countries have only carried out partial research on drones, and have not applied them to substation inspections to realize intelligent management of substations.

However, domestic research on the application of UAVs is limited to inspections of transmission lines, and has not been applied in substations.

[0003] In the existing technology, UAVs rely on GPS or Beidou navigation and positioning system for positioning and navigation, while the precision error of conventional navigation systems is within 2 meters. , Indoors and other places with narrow spaces and weak signals to carry out fixed-point inspections or autonomously planned path inspections. At present, the special technologies that are stably implemented in the industry have not come in handy.
