Assembly and method for growing perennial plants

The present invention relates to the cultivation of perennial plants.

More specifically, the present invention relates according to a first aspect to an assembly for the cultivation of perennial plants such as vines.

It is possible to map the vineyard plots. Such a mapping provides useful information to the winemaker: positions of missing vines, vigor of each foot, etc. This information allows him to plan maintenance work and determine the growing conditions for the following season.

The identification of missing stocks can be done for example with flying drones recording images of the vine. FR2852785 describes the use of light sensors on board machines circulating in the vineyards to determine the vigor of the vines.

Such operations are costly.

In this context, the invention aims to propose an assembly making it possible to carry out maps in a less costly manner.

To this end, the invention relates to an assembly for the cultivation of perennial plants such as vines, the assembly comprising:

- a cutting device comprising a portable cutting tool, an absolute location sensor of the cutting tool, and at least one sensor configured to acquire at least one operating parameter of the cutting tool;

- a data management device, configured to record the or each operating parameter acquired by associating with it the location of the cutting tool measured by the location sensor at the time of the acquisition of the or each operating parameter.

In certain seasons, typically during winter, all perennial plants in each plot are pruned. The invention takes advantage of the fact that the workers pass throughout the plot to carry out the mapping of the crop in an economical manner, during this same passage.

The use of electric cutting tools is now widespread. These cutting tools have a battery, and can be easily adapted for measuring and recording operating parameters.

In addition, GPS type sensors are now common and allow to locate an object with excellent precision. This precision is sufficient to carry out a mapping in a vine-type culture, where the feet are separated from each other by a distance of several tens of centimeters.

Mapping can therefore be carried out without additional dedicated passage in cultivation, and without requiring the use of sophisticated and expensive machines such as drones or laser measurement tools on board tractors.

The information collected advantageously makes it possible to make statistics on the use of the cutting tool, for example on the productivity of staff pruning perennial plants.

Other characteristics and advantages of the invention will emerge from the description which is given below, for information and in no way limitative, with reference to the appended figures, among which:

- Figure 1 is a schematic top view of a vine;

- Figure 2 is a schematic side view of the vine of Figure 1;

- Figure 3 is a schematic representation of a culture assembly according to the invention;

- Figure 4 is a schematic representation of the data management device of the assembly of Figure 1; and

- Figure 5 is a step diagram illustrating the culture method of the invention.

The invention relates to an assembly intended for the cultivation of perennial plants. Perennial plant is understood to mean a plant cultivated in the form of a tree, shrub, bush, and having a lifespan of several years. These perennial plants are typically vines, as shown in FIGS. 1 and 2. As a variant, these perennial plants are for example fruit trees, or olive trees, or ornamental shrubs such as roses, or floral plants.

The culture of perennial plants 1 typically comprises a plurality of plants 3 planted according to a determined pattern. This pattern is of any suitable type, depending on the nature of the plant.

For example, the plants 3 are arranged in several lines 5 parallel to each other. Plants 3 are regularly spaced along the same line. The lines have a constant spacing between them. Such an arrangement is used for the vine, as illustrated in FIG. 1.

For fruit trees or olive trees, the trees are arranged for example in a square mesh.

Typically, culture 1 comprises a plurality of stakes 7, and wires 9 fixed to the stakes 7 (FIG. 2).

The stakes 7 are generally placed along the lines 5 of plants. They are regularly spaced.

The wires 9 extend along the lines 5. Each stake 7 typically carries several superimposed wires 9. The branches 10 of the plants 3 are hung on the wires 9.

Such an arrangement is typically used in the vineyards.

Sometimes stakes 7 are missing and / or wires 9 are broken (see Figures 1 and 2).

The culture assembly 11 comprises (FIG. 3):

a cutting device 13 comprising a portable cutting tool 15, a sensor 17 for absolute location of the portable cutting tool 15, and at least one sensor 18 configured to acquire at least one operating parameter of the cutting tool 15;

a data management device 19, configured to record the or each operating parameter acquired by associating with it the location of the cutting tool 15 measured by the location sensor 17 at the time of the acquisition of each or each parameter of operation.

The cutting tool 15 is advantageously an electric pruner.

The cutting tool 15 comprises a handle 21 carrying a fixed blade 23.

The cutting tool 15 also comprises at least one movable blade 25 and a motor 27 for driving the movable blade 25. The movable blade 25 is for example pivotally mounted on the handle 21, the motor 27 driving the movable blade 25 in rotation relative to the fixed blade 23.

The cutting tool also includes a battery 29, electrically connected by a cable 31 to the motor 27. The battery 29 is generally housed in a clothing element 33 worn by the user of the cutting device 11, such as a belt or a vest.

The sensor 17 for absolute location of the portable cutting tool 15 is typically a GPS (Ground Positioning System), having an accuracy of less than one meter. In known manner, such a sensor 17 cooperates with one or more satellites 35 to determine the geographic position of the sensor 17 in the terrestrial frame.

The sensor 17 is typically mounted on the cutting tool 15 or on the clothing element 33.

The data management device 19 typically comprises a mobile information processing unit 37 and a remote information processing unit 39.

The mobile information processing unit 37 is carried by the cutting device 13, typically by the cutting tool 15 or the clothing element 33. The unit 37 is formed for example of a processor and d 'a memory.

The remote information processing unit 39 is for example a personal computer.

The data management device 19 comprises a communication interface 41 between the mobile information processing unit 37 and the remote information processing unit 39. According to an alternative embodiment, the communication interface 41 is configured so that units 37 and 39 communicate with each other remotely, by air. According to another alternative embodiment, the communication interface 41 is configured so that the units 37 and 39 communicate with each other by a physical connection, typically by cable.

In the case of over-the-air communication, the unit 37 is for example equipped to communicate with the unit 39 by any type of network: the wireless telephone network, a LORA type network, a SIGFOX type network, etc. . The recorded data is advantageously transmitted continuously when the network is available. When the network is not available, the data is saved in the memory of the unit 37, and is transmitted in a deferred manner to the unit 39 when the network is restored.

The mobile information processing unit 37 has sufficient capacity to record the acquired operating parameters and the associated locations during a certain operating time, for example a day or a half-day.

The remote information processing unit 39 is configured to store all the information collected concerning the same plot, and to process this information so as to evaluate a certain number of parameters relating to each plant, as described below.

The communication interface 41 is configured to transfer the information stored by the mobile information processing unit 37 to the remote information processing unit 39.

Typically, the sensor 18 is configured to acquire a parameter relating to the displacement of the movable blade 25. In other words, the operating parameter relates to the cut made by the cutting tool 15.

Advantageously, the sensor 18 is configured to detect that a cut has been made by the cutting tool. The saved operating parameter here is simply "making a cut". In the case of a vine, this typically corresponds to the cutting of a branch of a vine stem.

When the cutting tool 15 includes a trigger enabling the engine to be triggered and causing the cutting, the sensor 18 is for example provided to detect that the trigger has been actuated. Alternatively, the sensor 18 measures the current supplied to the electric motor 27, the movement of the movable blade 25 or is of any other suitable type.

The sensor 18 is advantageously configured to also measure the torque of the motor 27 at each cut. The operating parameter recorded here is the torque applied by the motor 27 to the movable blade 25.

Such sensors are known, and it is not necessary to describe them here in detail.

Thus, the same sensor 18 is configured to detect that a cut has been made and to measure the torque applied by the engine to said cut. The two parameters are saved for each cut.

As a variant, the cutting device 11 includes a sensor configured to detect that a cut has been made and another sensor to measure the torque applied by the motor to said cut. The two parameters are saved for each cut.

According to yet another variant, the cutting device comprises a sensor configured to only detect that a cut has been made. Only this parameter is saved for each cut.

According to yet another variant, the cutting device comprises a sensor configured to only measure the torque applied by the motor to said cutting. Only this parameter is saved for each cut.

Preferably, the cutting member 15 comprises at least one manual member for signaling the presence of at least one of a weed stain (H in FIG. 1), a hole (T in the Figure 1), a broken wire 9, a missing stake 7, one or more elements of crop management.

The or each element of conduct is indicative of the state or health of the culture.

The pipe element indicates for example that a plant is in a state of water stress, or in a state of deficiency in a chemical element, etc.

The driving element can also be a symptom of an illness or indicate the presence of harmful insects.

The presence of the control elements is detected by visual observation of the plants.

According to a variant, the cutting device 11 comprises a manual signaling member 43, and a manual selection member 45, making it possible to assign the member 43 selectively to the reporting of one of the above elements. Thus the same member 43 makes it possible to signal any of the above elements, as a function of the position of the selection member 45.

The manual signaling member 43 is for example a push button. The manual selection member 45 is for example a dial.

As a variant, the cutting device 11 comprises several manual signaling members, each dedicated to signaling the presence of one of the above elements.

The cutting device 11 as a variant comprises one or more configurable manual members, which are capable of being configured to signal the presence of any element of interest relating to culture,

According to an alternative embodiment, the sensor 18 being configured to record that the signaling member 43 has been actuated, the operating parameter then being "actuating signaling member".

The operating parameter "signaling device actuated" is recorded in addition to or in place of the parameter or parameters relating to the movement of the moving blade.

The sensor 18 recording that the signaling member 43 has been actuated is distinct from the possible sensor or sensors 18 measuring the other operating parameters.

In any event, the data management device 19 is configured to record said report by associating it with the location of the cutting tool 15 measured by the location sensor 17 at the time of the report.

This makes it possible to record the geographical position of the weed spots, holes in the ground, broken wires 9, and missing stakes 7 or of each element of crop management. This inventory is carried out while the worker is circulating in the crop to carry out pruning, and does not require a dedicated pass or the use of sophisticated equipment.

Preferably, the cutting device 11 comprises an orientation sensor 47 measuring the orientation of the cutting tool 15 relative to the vertical.

Such sensors are known and equip for example mobile phones. They will not be described here in detail.

In this case, the data management device 19 is configured to record, with the or each operating parameter acquired, the orientation of the cutting tool 15 at the time of the acquisition of the or each operating parameter.

In the case of vines, this makes it possible to determine whether the cutting is carried out on wood grown during the year or on old wood. The timber of the year grows vertically, and is therefore cut with the substantially horizontal cutting tool. Old wood is trellised horizontally, and is therefore cut with the substantially vertical cutting tool.

According to an advantageous alternative embodiment, this information is taken into account to determine the vigor of each plant, as described below.

According to another advantageous aspect, the data management device 19 is configured to record an identification reference of the cutting tool 11 or an identification reference of a user of the cutting tool 11.

Furthermore, the data management device 19 has a clock 49 indicating the current time. The data management device 19 is then configured to record, with the or each operating parameter acquired, the current time at which the acquisition of the or each operating parameter is carried out.

The clock 49 is for example on board the cutting tool or on the clothing accessory 33.

It is thus possible to record the time at which the cutting assembly 11 performs each cutting, and to make statistics on the time of use of each cutting assembly 11. It is in particular possible to calculate the duration of use of each cutting unit, cutting rate, area treated per unit of time, productivity of each user, etc. It is also possible to make comparisons, between two years or between two users.

Advantageously, a cutting plane is loaded into the data management device 19. The cutting plane contains the plants to be pruned by the user of the cutting tool. These plants are identified by an indication of absolute position. The plants are designated individually, or collectively (for example an entire row of vines).

The cutting device 13 is designed to make the cutting tool 15 inactive when the sensor 17 detects that the cutting tool 15 is not at a position appearing in the cutting plane.

For example, the power supply to motor 27 is cut in this case.

As a variant, the user is informed by any suitable means when the sensor 17 detects that the cutting tool 15 is not at a position appearing in the cutting plane.

This prevents an operator from passing a second time through an area of the crop that has already been cut. This also makes it possible to reserve the size of certain particularly sensitive plants for authorized operators.

Advantageously, the data management device 19 comprises a module 51 configured to determine the position of the missing plants 3 in the pattern according to which the plants 3 are arranged, using the recorded operating parameters and the associated locations.

The module 51 is configured to analyze the locations where cuts have been made. He concludes that a plant 3 is missing in the pattern for example if the following three conditions are satisfied:

1 / cuts were made along a line;

2 / there is a segment of the line without cut, framed by two segments of the line with cuts;

3 / the segment without cut has a length greater than a determined length.

The determined length is for example 1.5 m.

Other detection strategies are possible.

For the operation of module 51, it is sufficient to save the "cut performed" parameter and the associated location.

Preferably, the data management device 19 comprises a module 53 configured to determine a number of cut branches per plant, using the recorded operating parameters and the associated locations.

The module 53 is configured to analyze the locations where cuts have been made. For example, it first determines the location of each plant 3, then counts the cuts made within a predetermined radius around said plant 3.

The location of the plant here corresponds to the geographic position of the vine's stem or trunk. To determine this location, the module 53 determines for example the cutting density per unit area, the maxima corresponding to the positions of the vines or trunks.

The predetermined radius depends on the type of plant and the type of crop. It is worth for example 1 m.

According to an advantageous variant, the module 53 takes into account only the cuts made with the horizontal cutting tool 15, that is to say made on young wood.

For the operation of the module 51, it is sufficient to record the "cut performed" parameter and the associated location, possibly with the orientation of the cutting tool 15.

Advantageously, the data management device 19 comprises a module 55 configured to determine a cut branch diameter, using the recorded torque.

This operation is carried out for example for each cut.

In fact, the larger the diameter of the branch, the higher the torque to be applied to cut it.

The module 55 is configured to determine the diameter using a graph, or tables, or an equation, or by any other suitable method.

The graphs, tables, equations are for example different for each type of plant. They are typically determined experimentally.

Advantageously, the data management device 19 comprises a module 57 configured to determine an average diameter of cut branches for each plant, using at least the couples recorded.

More specifically, the module 57 is configured for example for:

- first determine the location of each plant,

- identify the cuts made on each plant;

- calculate the cut branch diameter for each cut;

- calculate the average diameter of the cut branch for each plant.

For the determination of the location of each plant, the module 57 is configured to use the information available in the module 53, or to recalculate this information according to the same method.

To identify the cuts made on each plant, the module 57 lists the cuts made within a predetermined radius around the plant. The predetermined radius depends on the type of plant and the type of crop. It is worth for example 1 m.

Advantageously, the module 57 takes into account only the cuts made with the horizontal cutting tool 15, that is to say made on young woods.

For the calculation of the cut branch diameter, the module 57 is configured to use the information available in the module 55, or to recalculate this information according to the same method.

For the calculation of the average diameter of the cut twig for one of the plants, the module 57 is configured to make, for example, the arithmetic average of the diameters of the cut twigs on said plant, using the values previously determined.

For the operation of the module 57, it is necessary to record the “cut performed” event, with the value of the torque applied by the motor for said cut, the associated location, and possibly the orientation of the cutting tool 15 .

Preferably, the data management device 19 comprises a module 59 configured to determine a quantity representative of the vigor of each plant by using the average diameter of cut branches and the number of cut branches for said plant.

Module 59 uses the data provided by modules 53 and 57.

The module 59 is configured to determine the diameter using a network of curves, or tables, or an equation, or by any other suitable method.

The curves, tables, equations are for example different for each type of plant. They are typically determined experimentally.

The representative quantity is for example a numerical index, the value of which increases between a minimum and a maximum with the vigor of the plant.

Preferably, the data management device 19 comprises a module 61 configured to store the recorded parameters and the associated location, as well as the results provided by the various modules 51, 53, 55, 57, 59, and possibly the positions of the plants. missing, weed stains, holes, broken wires, missing stakes and crop management items.

The module 61 is also configured to allow calculations to be made using the stored data, and to restore the data, calculations or results in different forms.

The module 61 is configured for example to calculate the time of use of each cutting tool 15, the cutting rate, the surface treated per unit of time, the productivity of each user, the time spent to cut each plot or each fraction. plot, etc.

The results are returned for example in the form of a map of each crop, on which are represented the plants and possibly the missing plants, the weed spots, the holes, the broken wires, the missing stakes and the driving parameters. . For each plant, the map indicates the corresponding numerical data: number of cut branches, average diameter of cut branch, size representative of the vigor of the plant, etc.

As a variant, the results are rendered in the form of a table, or of graphs of all types, or in any other suitable form.

The module 61 is advantageously configured for user monitoring: planning and identification of tasks, in particular pruning routes, allocation of cutting tools to users, productivity of each user, geolocation of each user.

For example, the module 61 is used to generate the section planes described above.

Thus, the data management device is a real data management platform.
