Drone structure for the transport of temperature-controlled material

A system for carrying a load at a controlled temperature, said system comprising at least one drone structure including:

• at least one motor arranged to move said drone structure;
• an energy unit arranged to deliver electric energy;
• a thermal container comprising:
• an insulating casing comprising at least one layer of heat-insulating material;
• at least one inner temperature sensor configured to measure a value of temperature Tint internal to said insulating casing;
• at least one outer temperature sensor configured to measure a value of temperature Text external to said insulating casing;
• a thermal unit arranged to adjust or keep constant said value of temperature Tint;
• and
• a control unit adapted for carrying out:
• an acquisition of a flight mission comprising:
• a landing position of said drone structure;
• a time limit tmax to reach said landing position;
• a condition on the values of said temperature Tint to keep during said flight mission;
• an acquisition of said temperature values Tint and Text;
• an acquisition of a value of energy Eres available in said energy unit;
• a calculation of a value of energy Eeng to provide to said at least one motor for bringing said drone structure in said landing position in said time limit tmax;
• wherein:
• said control unit is also adapted for carrying out:
• a calculation of a value of energy Eterm to provide to said thermal unit in order to respect said condition on the values of said temperature Tint to keep during said flight mission;
• a calculation of a value of overall energy Emis=Eeng+Eterm necessary to complete said flight mission;
• and
• a comparison between said values of energy Eres and Emis;
• and said control unit is programmed in such a way that:
• if Eres≥Emis then said control unit carries out at least one of the following actions:
• command to said at least one motor to proceed with said flight mission;
• transmission of a signal of sufficient energy, in particular sent by means of a warning light and/or a warning sound and/or a remote transmission;
• and
• waiting for an order by an operator and/or by a control remote unit;
• and
• if Eres<Emis then said control unit carries out at least one of the following actions:
• change of said flight mission according to a predetermined algorithm;
• implementation of strategies for reducing said value of said overall energy Emis and following new comparison between said values of energy Eres and Emis;
• transmission of a signal of insufficient energy, in particular sent by means of a warning light and/or a warning sound and/or a remote transmission;
• abort of said mission;
• and
• waiting for an order by an operator and/or by a control remote unit.
