| 摘要 |
The invention concerns a system (1) for characterising the physiological state of woody plants (2, 3) with branches grown in rows, such as vine plants, said system (1) including a vehicle (10) designed to move between said rows, a geolocation device (14) and a processing unit (15), and being characterized in that it includes a sensor (16) including a light source (17) designed to emit a light beam (18) and a light receiver (19), said light beam (18) being able to intersect the branches, as the vehicle (10) moves forward, said light beam (18) having a dimension (L) greater than the diameter (D) of the thickest of the branches in said row (6), said light beam (18) projecting, onto said light receiver (19), a shadow (20A, 208) from which the processing unit (15) determines the diameter (D1, D2 of the branch (2A, 28) in question. |

1. A system (1) for characterizing the physiological state of woody plants (2, 3) with branches (2A, 28, 2C, 2D, 2E, 2F, 2G, 2H, 2I, 2K, 3A, 38, 30, 3D, 3E, 3F, 3G, 3H, 3I, 3K) grown in rows (4, 5, 6, 78), of the vine or fruit-tree type, said system (1) comprising a vehicle (10) designed to progress between said rows (4, 5, 6, 7, 8) along a direction of progression X-X′, and also comprising a geolocation device (14) on-board said vehicle (10) as well as a processing unit (15), said system (1) being characterized in that it comprises a sensor (16) including a light source (17) designed to emit a light beam (18) and a light receiver (19), said light source (17) and receiver (19) being mounted on said vehicle (10) so as to be able to be arranged on either side of a row (6), so that said light beam (18) can intersect, as the vehicle (10) progresses along said row (6), branches 2B, 2C, 2D, 2E, 2F, 2G, 2H, 2I, 2K, 3A, 3B, 3C, 3D, 3E, 3F, 3G, 3H, 3I, 3K) belonging to the woody plants (2, 3) of said row (4, 5, 6, 7, 8), said light beam (18) having, in the direction of progression X-X′, a dimension (L) that is substantially higher than the diameter (D) of the greatest of the branches of said row (6), so that the interposition of a branch (2A, 2B, 2C, 2D, 2E, 2F, 2G, 2H, 2I, 2K, 3A, 3B, 3C, 3D, 3E, 3F, 3G, 3H, 3I, 3K) between the light source (17) and receiver (19) cut only partially said light beam (18) and hence projects on said light receiver (19) a shadow (20A, 20B) from which the processing unit (15) determines the local diameter (D1, D2) of the concerned branch (2A, 2B), said processing unit (15) being further designed to associate with said local diameter (D1, D2) of the concerned branch (2A, 2B) information of geolocation of said branch (2A, 2B) corning from the geolocation device (15). |
