Description

DEVICE AND SYSTEM FOR MONITORING THE RISK OF INFESTATION OF PESTS IN A CEREAL STORAGE ENVIRONMENT

Technical area

The present invention relates to the field of pest control.

The present invention relates more particularly to a device and a system for monitoring a risk of infestation making it possible to identify factors for the proliferation of pests in a cereal storage environment.

By risk of infestation within the meaning of the present, is meant throughout the following description any element making it possible to characterize the presence, the species, the number and/or the conditions favorable to the installation and/or the development of a population of insect pests, especially weevils.

The present invention will thus find numerous advantageous applications in the field of food safety, and in particular in the remote monitoring and over the duration of cereal silos.

State of the art

The Applicant observes that the long-term storage of cereals, in particular grains or rice, represents a risk of infiltration of pests, in particular weevil-type insect pests, which reproduce within the cereal.

Monitoring stored cereals is therefore essential to preserve stocks and to prevent the proliferation of pests.

To locate harmful insects, it is already known to employ a variety of insect traps in or around storage. Such traps do not alone protect a grain reserve, but provide staff with a visual indicator of the presence of insects encouraging the use of pest control solutions, in particular via storage pesticides.

This use of storage pesticides can occasionally eliminate the majority of pests, but their excessive use represents a health risk, increased toxicity to the environment and leads to the appearance of more resistant pest species.

The insect trap solutions currently proposed are therefore limited to providing an indicator of the presence of insects, which must be noted manually by personnel on site. The staff present on the cereal storage sites is itself limited, in particular for economic reasons resulting from reduced storage margins. The Applicant therefore submits that to date there is no satisfactory alternative solution allowing remote monitoring of a risk of infestation to minimize personnel, pesticides and the means used to avoid the proliferation of pests within of a grain silo.

Summary of the invention

The present invention aims to improve the current situation described above.

The present invention aims more particularly to remedy the above drawbacks by proposing a solution capable of detecting parameters associated with a risk of infestation and transmitting them to induce an appropriate reaction.

To this end, the object of the present invention relates in a first aspect to a trap device for insects in a cereal storage environment comprising an elongated hollow body having a middle portion comprising a plurality of openings opening into an internal volume the middle portion defining a zone for capturing insects and a lower portion, the internal volume of which defines a zone for trapping insects, the middle portion and the lower portion being connected by a non-return opening system.

The present invention consists of a real trap capable of trapping insects in a grain storage environment.

Thus, it is possible to position the trap in a cereal storage environment. Once positioned, the hollow body, for example of cylindrical shape, is designed so that the insects enter the capture zone by crossing one of the openings of the middle portion, then enter the trapping zone through the non-return system , which blocks or slows their exit from the trapping zone. The insects can be attracted into the capture zone and/or into the trapping zone by a plurality of means known to those skilled in the art, for example by the use of pheromones or other composition placed in the trapping zone and attracting the insects and/or by a gravity trapping system in which the hollow body extends in a substantially vertical direction, the trapping zone being arranged under the capture zone and the insects being caused to fall in or towards the zone of trapping. The openings have, for example, a round shape with a diameter of between 2 mm and 5 mm, preferably 2.5 mm, or even an oval shape with dimensions substantially equal to 4 mm by 2 mm. Of course, the openings are dimensioned in a manner adapted to the pest whose presence is suspected and according to any performance associated with a specific shape or dimension.

It is understood here that the non-return system facilitates the passage of insects from the capture zone to the trapping zone and slows down or prevents the passage from the trapping zone to the capture zone. It may in particular be a membrane separating the middle and lower portions and having a funnel shape, the flared part of which is oriented towards the capture zone and the narrowed part is oriented towards the trapping zone. The trapping zone may additionally comprise other means known to those skilled in the art for retaining the insects, for example an internal surface covered with an adhesive substance.

Advantageously, the device comprises an on-board electronic module comprising at least one detection sensor configured to capture at least one piece of information representative of a risk of infestation in the trapping zone and to generate at least one piece of risk data containing the at least one information.

It is understood here that the risk datum may correspond to an aggregation of the at least one piece of information or even to the result of a processing of the at least one piece of information, with the aim of identifying factors for the proliferation of pests.

Advantageously, the on-board electronic module comprises wireless transmission means configured to transmit the at least one risk datum to a remote electronic entity.

The remote electronic entity may correspond to a server or a database dedicated to monitoring the risk of infestation associated with one or more devices, to a personal electronic entity such as a laptop or smart phone or even to a relay in communication with such a remote electronic entity.

Thanks to the present invention, the risk of infestation of a given environment by harmful insects can be monitored remotely from in situ means.

In an advantageous embodiment of the invention, the electronic module comprises a control circuit for the at least one sensor configured to control the capture of information according to a determined capture frequency.

In other words, the control circuit makes it possible to trigger the activation of the at least one sensor once per determined period, thus making it possible to keep the at least one sensor in a state of standby or equivalent the rest of the time. . This design makes it possible to limit the energy consumption of the device and to increase its autonomy.

Preferably, the capture frequency is substantially equal to one capture per day. This frequency makes it possible to have sufficient monitoring while limiting the associated energy consumption as much as possible. It is also possible to design a minimum frequency of one capture every 7 days or even a frequency outside periods of activity of one capture every 14 days in winter to ensure minimum monitoring allowing preventive actions taking into account a seasonality of the risks of proliferation of insects.

In a specific embodiment, the at least one risk datum contains:

- information representative of a visual representation of the trapping area; and or

- information representative of the presence of insects; and or

- information representative of a number of said insects; and or

- information representative of a filling rate of the trapping zone; and or

- information representative of an ambient temperature; and or

- information representative of ambient humidity.

It is understood here that the at least one piece of risk data comprises one or more of these pieces of information in combination according to the number and type of sensors used as well as according to a possible processing of the representative information(s) allowing the generation of additional representative information. .

In a particular embodiment, the at least one sensor comprises:

- a camera ; and or

- a thermal sensor; and or

- a vibration sensor; and or

- a sound sensor; and or

- a hygrometer.

It is understood here that, for example, the camera makes it possible to provide at least one piece of information representative of a visual representation of the trapping volume, and that the thermal sensor makes it possible to provide at least one piece of information representative of an ambient temperature.

Those skilled in the art will understand that the constituent elements of at least one sensor can be selected according to their individual performances or according to their respective synergies to assess a risk of infestation. For example, the camera makes it possible to determine the presence of insects in the trapping volume, which can be combined with a temperature measured by the thermal sensor to assess whether the environment is favorable for their reproduction.

In an additional embodiment, the at least one sensor is placed in the trapping zone.

This design makes it possible to obtain direct information from inside the trapping zone by minimizing the risk of interference from elements external to the trapping zone. For example, the camera gets a clear view of the trapping area. Of course, other sensors that do not specifically require obtaining information associated with the trapping zone can be arranged at any other favorable location of the device.

In another embodiment that can be combined with the previous mode, the non-return opening system comprises means for fixing the at least one sensor.

It is understood here that the sensor can be fixed to a wall of the non-return system on the side of the trapping zone, which facilitates the assembly of the elements and limits the size of the trapping zone by the at least one sensor .

Preferably, the non-return opening system has a funnel shape comprising a channel, the fastening means being arranged in the channel.

This design makes it possible, for example, to facilitate the counting of insects entering the trapping zone, by detecting a disturbance associated with the passage of an insect, for example a vibration or a variation in light intensity.

In an additional embodiment, the body comprises in the upper portion a storage area configured to house at least one electronic component of the electronic module from among the following:

- the means of transmission; and or

- the control circuit; and or

- a battery-type power supply.

It is understood that the storage area makes it possible to embed electronic equipment in the device without hindering the trapping of insects. Of course, it is also possible to design other variants of positioning of the storage zone according to the desired overall shape of the device and the criteria associated with the capture, trapping and storage zones. The presence of an on-board battery ensures device autonomy over a certain period depending on its energy consumption, without constraints from the energy network or external conditions.

Preferably, the storage area comprises at least one positioning pin configured for receiving and positioning the at least one electronic component.

This design makes it easier to assemble the device by precisely pre-sizing each pin and associated electronic component. The at least one positioning pin additionally makes it possible to fix the at least one electronic component in a stable manner to secure the handling of the device and increase its lifespan.

The positioning pin can also be replaced by at least one fin and/or rib in the storage zone depending on the design of the device and fulfilling an identical function. In an additional mode of implementation, the capture zone and the storage zone are separated from each other by a partition preventing the passage of insects to the storage zone.

It is understood here that the storage area is isolated from the external environment and from the rest of the device in order to prevent the infiltration of insects that could damage the at least one electronic component.

In an additional mode of implementation in which the at least one sensor is arranged in the trapping zone, the middle portion of the body comprises at least one guide sized for the passage of at least one cable ensuring the electronic connection between the at least one sensor and the other components of the on-board electronic module.

It is understood here that the at least one cable makes it possible to supply an electrical power supply to the at least one sensor, as well as the transmission of information in both directions, for example an activation command from the control circuit to a sensor and a sensor signal in the reverse direction.

It is additionally understood that the position of the at least one cable in the body is defined beforehand by the position in the body of the at least one associated sensor, of the other components of the electronic module and of any openings in the partition and/or or the non-return system for the passage of the at least one cable.

The guide corresponds, for example, to one or more lateral chutes made in the body of the device or even to point fixing means made on the internal surface of the hollow body or even held in the center of the hollow body.

In a particular mode of implementation, the body is produced by molding or by machining. Those skilled in the art understand here that manufacturing by molding, for example plastic injection molding, makes it possible to produce a hollow body or part of a hollow body to be assembled at a reduced cost on large series, while manufacturing by Machining makes it possible to produce parts with more complex shapes to obtain specific functionalities, for example from profiled tubes. The body can be made in several parts able to be assembled and allowing the housing of elements such as the electronic module, for example by making two complementary half-shells.

In a specific mode of implementation, the at least one sensor is of the camera type and is configured to capture at least one image of the trapping zone and in which the trapping zone is made of a material having a low coefficient of light reflection avoiding the presence of reflections on the camera lens. It is understood here that the internal surface of the trapping zone is designed so as to improve the quality of the image received by the camera. The material of the surface, or possibly of a coating on this surface, is thus chosen so as to minimize reflections on the lens of the camera, in particular if this camera is equipped with diodes of the LED type configured to light up when of the shot.

The bottom of the trapping area can also be designed to improve the quality of the visual representation, in particular by presenting a shape allowing the spreading of the insects. The background can also have a clear or transparent color, preferably white, to optimize the visual contrast with the insects.

In yet another embodiment, the lower portion of the body has a plurality of graduations along its length.

This design facilitates the image processing operations described below, for example to better assess the filling rate of the trapping zone or estimate the number of insects trapped.

In another mode of implementation, the lower portion of the body has a narrowed and elongated shape facilitating the measurement of a filling rate of the trapping volume.

This design also makes it easier to estimate a trap filling rate, while maintaining a simple shape that does not require an additional manufacturing step.

A second aspect of the present invention relates to a system for monitoring the risk of infestation within a cereal storage environment, which comprises at least one trap device according to the first aspect of the invention integrated into the environment. storage, a remote electronic entity configured to collect at least one piece of risk data generated by the at least one device and transmit the at least one piece of risk data collected to a remote server.

The at least one device is for example introduced into a stock of cereals so that the capture zone and the trapping zone are completely buried in the cereals and the storage zone is at least partially exposed to the outside to facilitate sending the at least one risk datum by the transmission means without interference due to the medium. It is understood here that the remote electronic entity serves as a relay between the at least one device and the remote server. The remote electronic entity is for example integrated in or close to the cereal storage environment and is directly connected to an electrical network so as to facilitate communication from the at least one device without constraining the transmission of the at least one risk datum to the remote server. The remote electronic entity may additionally comprise internal storage means, for example to group together a plurality of risk data over time before transmission to the remote server.

As stated above, the remote server may correspond to a server or a database for monitoring the risk of infestation within at least one storage environment making it possible to group the risk data of at least one device over time, to provide access to risk data via an application and/or to perform additional processing operations on risk data.

The at least one device, the remote electronic entity and the remote server can communicate according to a wireless communication mode, for example according to a radio communication technology. The remote electronic entity creates, for example, a local wireless communication network on which the at least one device is capable of transmitting information.

Preferably, the at least one sensor is of the camera type and is configured to capture at least one image of the trapping zone and the electronic module comprises image processing means implementing an image processing algorithm configured for :

- detect the presence of insects; and or

- identify at least one species associated with insects; and or

- count the insects; and or

- estimate a filling rate of the trapping area.

It is understood here that the image processing means are selected according to energy consumption criteria so as to limit as much as possible the total energy necessary for the at least one device to process and transmit the at least one risk datum .

Of course, the remote server and/or the remote electronic entity can also implement all or part of the image processing means according to the respective capacities of the at least one device, the remote electronic entity and the remote server. The image processing algorithm may correspond to any means well known to those skilled in the art, for example an automatic learning algorithm (in English "machine learning", literally "machine learning") centered on the recognition of objects and performed by a neural network. Such an algorithm makes it possible to analyze complex images while gradually improving the speed and accuracy of the analysis. The neural network can additionally be selected according to criteria associated with energy consumption or with the quality of the processed image. Thus, through the various functional and structural technical characteristics above, the Applicant proposes an insect trap device allowing the generation and transmission of at least one piece of risk data for the remote monitoring of the risk of infestation of a storage environment by pests.

detailed description

The present invention will now be described in the following with reference in conjunction to Figures 1 to 6 appended to the description.

As indicated in the preamble of the description, the current solutions of insect traps do not on their own make it possible to prevent their proliferation within an environment. of storage, and the local management of pest control operations is constrained by the available personnel and the location of the storage environment.

One of the objectives of the present invention consists in collecting on the spot the data relevant to such piloting by taking into account the lack of accessibility of the traps on a daily basis.

This is made possible in the example described below.

It will be understood here that this example is not limiting and that the invention will find other applications for the control of pests in other environments, for example around vulnerable crops.

According to the example of FIG. 6, a plurality of devices 1000a, 1000b and 1000c developed within the framework of the present invention are introduced within a stock of cereals 4100 of a storage environment 4000, for example a stock of cereals 4100 vulnerable to infestation by weevil-type insects. Devices 1000a, 1000b and 1000c can be designed specifically to trap these insects and have a structure similar to device 1000 as shown in Figure 1.

This device 1000 comprises a hollow and slender body 1100 extending along an axis X, for example a substantially vertical axis X, the body 1100 comprising a middle portion 1110, a lower portion 1120 and an upper portion 1130. This body 1100 is for example produced in several complementary parts by a molding operation, for example plastic injection molding, by a machining operation or even by a combination of such operations. Of course, the production method will be mainly selected according to economic criteria linked to the size of the manufacturing series and/or to the manufacturing constraints imposed by the design of the body 1100.

The middle portion 1110 has a plurality of openings 1112 able to let the insects pass towards the capture zone 1111 defined by the internal volume of the middle portion 1110. The openings 1112 have for example a shape and dimensions known to man trade to facilitate the capture of weevils, for example a round shape of 2.5 mm in diameter, an oval shape of 4 mm by 2 mm or any other suitable shape.

As illustrated by FIGS. 1 and 2, this middle portion 1110 is connected to the lower portion 1120 by a non-return opening system 1200, which for example has a funnel shape comprising a channel 1220 (FIG. 2) oriented towards the lower portion 1120. This non-return opening system facilitates or releases the passage of insects from the capture zone 1111 to a trapping zone 1121 defined by the internal volume of the lower portion 1120, while limiting or preventing the passage of insects in the other direction. Optionally, the trapping of insects can be facilitated by a variety of means, for example by a vertical design of the body 1100 positioning the trapping zone 1121 below the capture zone 1111 and allowing gravity trapping, by the application of a substance anti-adherent on the internal walls of the middle portion 1110, by placing baits, pheromones or the like in the trapping zone 1121 and/or the capture zone 1111 or else by a combination of these means.

It is understood here that the association of the capture zone 1111 with the trapping zone 1121 via the non-return opening system 1200 ensures the operation of the insect trap. It is of course possible to envisage other designs of the body 1100 combining these three elements and making it possible to adapt the trapping functionality according to a variety of constraints without departing from the scope of the invention.

In addition to the function of trapping insects from the cereal stock 4100, the device 1000 comprises an electronic module 1300, for example the electronic module 1300 illustrated in FIG. 5 comprising a plurality of elements. The elements of the electronic module 1300, for example the elements 1310, 1320, 1330, 1340, 1350 and 1360, individually or in combination, can be integrated into a single integrated circuit, into several integrated circuits, and/or into discrete electronic components .

Thus, the electronic module 1300 comprises at least one sensor 1310 configured to return information representative of a risk of infestation, for example a sensor of the camera type associated with a temperature sensor configured to return information representative of a visual representation of the trapping zone 1121 and at least one piece of information representative of an ambient temperature, for example the temperature of the trapping zone 1121 or of the stock of cereals 4100. This representative information can be grouped together in the form of at least one datum of risk, which is returned by the at least one sensor 1310.

According to the example of FIGS. 1 and 2, the at least one sensor 1310 can be arranged directly in the trapping zone 1121. It is possible, for example, to design a sensor 1310 of the camera type oriented in the direction of the bottom 1122 of the trapping zone. 1121. In this example, the trapping zone 1121 can additionally be designed so as to optimize the quality of the image received by the camera, in particular by having an internal surface made up of a material that is not very reflective to limit the effects of reflection from light on the camera lens, by designing a bottom 1122 to facilitate insect spreading and/or having a white or transparent color to improve contrast with the insects, by graduating the trapping area 1121 or even by designing a particularly elongated trapping zone 1121 to monitor the trapping of new insects over time.

As illustrated in FIG. 2, the non-return opening system may comprise means 1210 for fixing the at least one sensor 1310. Of course, the fixing means 1210 are arranged according to the desired positioning and orientation of the sensor. at least one sensor 1310. According to another design, the fixing means 1210 can be arranged in the channel 1220 of the non-return opening system 1200, for example to center the at least one sensor 1310 in the trapping zone 1121 or to orient it in the channel 1220 so that the passage of an insect activates the at least one sensor 1310 for counting insects.

The electronic module 1300 additionally comprises wireless transmission means 1320 configured to transfer the at least one risk datum to a remote electronic entity 2000. As illustrated by FIG. 6, the remote electronic entity 2000 can be an integrated fixed relay to the storage environment 4000 configured to collect risk data from devices 1000a, 1000b and 1000c and transfer it to a remote server 3000 within an infestation risk monitoring system 10000. The wireless communication between the devices 1000a, 1000b and 1000c, the remote electronic entity 2000 and the remote server 3000 uses for example a mode of communication based on a radio communication technology such as Bluetooth®, Wi-Fi®, LTE (from English "Long-Term Evolution" or in French "Evolution à Long Terme") or even LTE-Advanced (or in French "LTE-Advanced"), preferably using a private communication channel and wireless transmission means 1320 include for example an RF radiofrequency interface of the respective type.

Obviously, the wireless communication of the devices 1000a, 1000b and 1000c to the remote electronic entity 2000 and the wireless communication of the remote electronic entity 2000 to the remote server 3000 can use different technologies adapted to local constraints. The remote electronic entity can for example create a local communication network allowing the collection of data from the devices 1000a, 1000b and 1000c according to a short-range communication consuming limited energy, and communicate with the remote server 3000 according to a communication mode at long range less restricted.

According to the tracking system 10000 illustrated in FIG. 6, the remote server 3000 then makes it possible to group the risk data associated with a plurality of devices 1000a, 1000b and 1000c associated with a storage environment 4000 and to make them accessible to a user of the type responsible or manager of the storage environment 4000, for example via a dedicated application, to allow remote monitoring of the risk of infestation of the storage environment 4000 and for example to control the preventive actions and/or or remedies arising of this risk data. It is also possible to design a monitoring system 10000 comprising a remote server 3000 in communication with a plurality of relays 2000 respectively associated with a plurality of storage environments 4000 with the aim of centralizing the risk data even more and allowing simultaneous management. of the plurality of storage environments 4000.

As illustrated in FIG. 5, the electronic module 1300 can comprise other elements that fulfill auxiliary functions to the at least one sensor 1310 and to the transmission means 1320. In particular, the electronic module 1300 can comprise a control circuit 1330 configured to command the capture of information from the at least one sensor 1310, for example by an activation command of the at least one sensor 1310 according to a capture frequency. This capture frequency will be determined in such a way as to save the energy consumption of the electronic module 1300 as much as possible while providing risk data frequent enough to follow the evolution of the grain stock 4100 and allow the timely implementation of preventive and/or corrective actions by the user. The capture frequency can for example be set at one capture every 7 days during periods of activity and/or reproduction of the weevil and at one capture every 14 days outside the period. In a more secure design, the capture frequency can also be set to one capture per day. Of course, the capture frequency can be variable within the framework of a plurality of sensors 1310, for example a capture every two hours for a temperature sensor associated with a capture every day for a camera type sensor.

According to a particular design illustrated in FIG. 5, the transmission means 1320 and the control circuit 1330 can be included in an electronic card 1370, for example an electronic card comprising a processor, integrated memory, an input/output interface allowing communication with the other electronic components of the electronic module 1300 and various circuits known to those skilled in the art, the integrated memory storing the computer code of the on-board software or software comprising the instructions to be loaded and executed by the processor, in particular the instructions allowing to determine the frequency of capture.

As illustrated in FIG. 1, the electronic card 1370 is for example placed in a storage zone 1131 defined by the internal volume of the upper portion 1130. In a vertical design of the body 1100, this positioning makes it possible to introduce the device 1000 into the grain stock 4100 such that the top portion 1130 is at least partially exposed out of the grain. The operation of the transmission means 1320 is then simplified. Optionally, the storage area 1131 is connected to the capture area 1111 and to the rest of the body 1100 by a partition 1400, which makes it possible to isolate the storage volume 1131 from the capture area 1111 and to prevent the introduction of insects that can disrupt the operation of the electronic card 1370. Other electronic components can be positioned in the storage area 1131, in particular a battery 1340 ensuring the autonomy of the electronic module 1300. This battery 1340 is sized so as to reach a level of autonomy predefined according to the expected consumption of the electronic module 1300 and in particular the frequency of capture, preferably an autonomy of one year.

The storage zone 1131 can additionally comprise positioning pins 1132 intended to receive the electronic components, for example the battery 1340 illustrated in FIG. 1. Such positioning pins make it possible to facilitate the assembly of the device by the user by indicating and by securing the placement of the electronic components in the device 1000.

In addition to the design of the electronic module 1300 according to several discrete electronic components, these can be connected by at least one cable 1350 ensuring the transfer of energy and information. The device 1000 can in particular be designed so as to allow the passage of a cable 1350 from the storage area 1131 to the trapping area 1121 by creating openings in the partition 1400 and the non-return opening system 1200 sized to obstruct the passage of insects when the 1350 cable is positioned there. The middle portion 1110 may additionally comprise at least one guide 1113a, 1113b as illustrated in FIGS. 3 and 4 allowing passage of the cable 1350. This guide 1113a, 1113b may correspond to a central guide 1113a held in position by at least one arm 1114 (FIG. 3) enabling the cable 1350 to pass through the center of the capture zone 1111 without blocking the openings 1112 or even to at least one side chute 1113b (FIG. 4) releasing the greatest possible volume of the capture zone 1111 It is also possible to conceive of other means of guiding the cable 1350, in particular by means of fastening clips or hooks arranged on the internal wall of the middle portion 1110.

Finally, in the example of a sensor 1310 of the camera type, the electronic module 1300 can comprise image processing means 1360 configured to process the information representative of a visual representation of the trapping zone 1121. These means image processing 1360 can be included in the electronic board 1370 or, as stated above, correspond to a discrete electronic component disposed in the storage area The image processing means 1360 implement at least one image processing algorithm known from the state of the art, for example a CNN type neural network (“Convolutional Neural Network” or in French “Réseau de convolutional neurons”) or any other suitable type. This neural network may have passed a learning stage from a library of “labeled” images representative of a trapping zone including or not including insects of species likely to be encountered or even from data raw according to the means used, the examples available and the degree of precision achievable. The image processing algorithm, once trained, can return a plurality of values representative of a risk of infestation, for example a value representative of the presence of insects, a value representative of a species associated with insects, a value representative of a number of insects identified, a value representative of a filling rate of the trapping zone 1121, or any other representative value that can be used for estimating a risk of infestation. The values returned by the image processing means can subsequently be included in the risk datum transmitted by the wireless transmission means 1320.
