Track inspection system based on unmanned aerial vehicles

The invention provides a track inspection system based on unmanned aerial vehicles. The system comprises multiple groups of unmanned aerial vehicle groups carrying various kinds of sensors, a wirelesscommunication module and a background concentrating monitoring management unit; the unmanned aerial vehicle groups perform track inspection along railways according to preset flight circuits; duringthe flight process, various kinds of photographed track image information is transmitted to the background concentrating monitoring management unit through the wireless communication module; accordingto the background concentrating monitoring management unit, control instructions are transmitted to the unmanned aerial vehicle groups through the wireless communication module to control the operation and running of the unmanned aerial vehicles, and track operating states are stored, output and displayed according to various kinds of fed back signals. The system has the advantages of being scientific in designing, strong
