Site management system, in-flight detection method, and non-transitory computer readable medium storing program of site management system

A in-flight detection method using an unmanned airplane being switchable between an airplane mode for high speed flight and a VTOL mode for low speed flight, a working vehicle working in a civil construction site, and a shape detection sensor provided in the unmanned airplane, the shape detection sensor being driven to detect a shape of the civil construction site, the method comprising the steps of:

• setting an observation area within the civil construction site, the observation area including at least a working place in which the working vehicle executes a working process;
• moving the unmanned airplane to the observation area in the civil construction site by performing the high speed flight of the unmanned airplane in the airplane mode;
• driving the shape detection sensor of the unmanned airplane;
• detecting a shape of the observation area by performing the high speed flight of the unmanned airplane in the airplane mode while driving the shape detection sensor or by performing the low speed flight of the unmanned airplane while driving the shape detection sensor;
• and
• controlling flight of the unmanned airplane, driving of the working vehicle, and driving of the shape detection sensor in cooperation with each other by a single external control apparatus.

A non-transitory computer readable medium storing a program for executing a control process with a single external control apparatus, the control process comprising:

• setting an observation area within a civil construction site, the observation area including at least a working place in which a working vehicle executes a working process;
• moving an unmanned airplane to the observation area in the civil construction site by performing high speed flight of the unmanned airplane in an airplane mode;
• driving a shape detection sensor provided in the unmanned airplane to detect a shape of the civil construction site;
• detecting the shape of the observation area by performing the high speed flight of the unmanned airplane in the airplane mode while driving the shape detection sensor or performing low speed flight of the unmanned airplane in a VTOL mode while driving the shape detection sensor;
• and
• controlling flight of the unmanned airplane, driving of the working vehicle, and driving of the shape detection sensor in cooperation with each other by the single external control apparatus.
