Abstract

Device (1) for detecting a position (P) of a shutter (2) of an opening of a container (3), comprising at least one energy generator, at least one force sensor (11) measuring a force exerted on the force sensor (11) by the shutter (2), at least one electronic card (12) determining at least the position (P) of the shutter (2) as a function of the measured force, at least one transmitter (13) transmitting at least the position (P) of the shutter (2) by means of radio technology, characterized in that the transmitter (13) is electrically powered by the at least one energy generator intermittently.

Claims

closing (THhaut).

7. Detection method (100) according to claim 6, comprising an initialization step (El) in which the shutter (2) is defined in the closed position (F), and a reference value (Vref) is determined as a function of the at least one measurement (M) carried out by the force sensor (H).

8. Method (100) according to claim 7, comprising a step of resetting (EU) the reference value (Vref) in which the reference value (Vref) is modified as a function of the at least one measurement (M) carried out by the force sensor (11), the resetting step (EU) being carried out as a function of the previous position (P) of the shutter (2), and of a result of a comparison between the at least one measurement (M) carried out by the force sensor (11) and the initialization criterion (THmin).

9. Detection method (100) according to any one of claims 6 to 8, in which the opening criterion (THbas) and / or the closing criterion (THhaut) are defined as a function of the reference value (Vréf

10. )• Detection method (10) according to any one of claims 6 to 9, in which the shutter (2) is defined in the closed position (F), during the closing detection step (EO-F), also as a function of a result of a comparison between a standard deviation (o) calculated between at least two successive measurements (M) carried out by the force sensor (11) and a dispersion criterion (O;).

11. Container (3) configured to be movable on a vehicle and comprising a detection device (1) according to any one of claims 1 to 5. 2 [Fig. 3] 31
