The application discloses a limited space
toxic gas gradient detection
system and method based on a UAV, and the
system comprises the following steps: a multi-sensor integrated module is installed at the bottom of a UAV platform, and the module comprises a
hydrogen sulfide electrochemical sensor, an
oxygen optical sensor, a positioning module and a
laser radar; a controller is connected with the UAV platform, the multi-sensor integrated module and a communication module; and a
data processing terminal is connected with the controller through
wireless communication. The method comprises the following steps: a two-dimensional
vertical plane model of a vertical detection plane is generated based on
LiDAR data, a plurality of detection points arranged in a
matrix form are divided from the two-dimensional
vertical plane model, spatial coordinate information,
hydrogen sulfide gas concentration data and
oxygen concentration data of each detection point are collected, and
hydrogen sulfide and
oxygen concentration data of all horizontal
layers in the vertical direction are calculated based on the detection data by using a
Kriging interpolation
algorithm. The
system and method can automatically realize high-precision gradient detection of toxic gases in the vertical direction in a limited space.
