Crop protection system for an agricultural vehicle and associated protection method

A system for protecting a plot of crops, comprising a protection device adapted to be mounted on an agricultural vehicle including at least one tool for treating crops, said vehicle comprising forward movement means allowing it to move forward in a direction “of forward movement” within a plot of crops, said crops being called upstream when they are located upstream of the at least one treatment tool before the passage of the at least one treatment tool over the crops with respect to the direction of forward movement, and said crops being called being treated when they are located at the at least one treatment tool during the passage of the at least one treatment tool over the crops;

• said protection device being characterized in that it is configured to:
• measure at least one characteristic value of crops being treated, in particular the size or the position in space of a crop;
• said system further comprising a control unit configured to:
• receive a measurement of the at least one characteristic value coming from the protection device;
• identify a state of said crop being treated, wherein said state can be a “deteriorated” state or a “preserved” state;
• transmit a signal for protecting the plot of crops to the agricultural vehicle or to a remote terminal when the crop being treated is in a deteriorated state.
