Description

Device and method for detecting events relating to an area comprising at least one wire, alerting device and method.

[0001] This presentation relates to the general field of event detection from a vibration wave.

[0002] The present invention relates more particularly to areas containing at least one wire, such as trellised crop areas. Trellising consists of supporting plants (trees, vines, grapevines, etc.) so that they can produce a maximum of fruit without breaking due to the weight of the fruit or due to climatic conditions (wind, rain, snow on green plants). Today, there is a real need, generally in open-field crops but also in greenhouse crops, to prevent theft of fruits and vegetables in the fields. These growing areas, as well as other locations such as outdoor livestock areas, and large fenced areas such as private company or residential properties, are often both open and vast, making them difficult to secure using known surveillance methods: video surveillance and law enforcement patrols.These areas, particularly cultivated fields (often referred to simply as "crops," though this is a misnomer), are therefore very poorly protected against theft. Video surveillance requires real-time analysis, which is impossible without automated assistance (using Artificial Intelligence). Consequently, it is only truly effective after the fact has been discovered, in an attempt to identify the perpetrators. Furthermore, these areas, especially cultivated plots and even some livestock farms, rarely have a permanent power supply, further complicating the use of this surveillance method. Finally, video capture can be degraded or even rendered inoperable by weather conditions (rain, fog), lighting conditions (night, backlighting), the presence of the crops themselves or other crops / vegetation obscuring the area to be protected, or by deliberate actions, such as covering the camera lens.Protection by law enforcement or by the farm operators themselves through patrols aims to deter thieves and can lead to arrests. However, this approach consumes significant resources and proves insufficient on very large properties. Another security approach involves installing protective fencing. This method can be effective in enclosed spaces such as greenhouses, but it is very complex to implement on large open areas, particularly orchards.

[0003] There is therefore a real need for securing areas, particularly crops, which is free, at least in part, from the disadvantages inherent in the aforementioned known configurations.

[0004] The present presentation concerns a device for detecting events relating to an area containing at least one wire, comprising: - an analyzer capable of analyzing at least one representative vibration wave signal emitted by at least one wire of said area to determine, based on said representative vibration wave signal captured, at least one event relating to said area, the vibration wave having been triggered by the event on the wire.

[0005] Advantageously, this disclosure allows the use of vibrations detected on at least one wire, such as a support wire, to identify events associated with the area. Such a detection method is far less intrusive and more discreet than cameras. Since the device is preferably small, it can be camouflaged in various areas, particularly in cultivated fields, and thus remain undetected by thieves.

[0006] According to some embodiments, the device comprises: - a receiver capable of receiving said at least representative vibration wave signal from at least one vibration wave sensor positioned on said at least one wire.

[0007] The sensors can also be small and therefore very discreet, which can advantageously prevent vandalism, unlike the event detection device. Several sensors can be arranged, for example, on the same wire or on different wires. This can advantageously allow for more precise determination of the location within the area associated with the event. This can be useful for pinpointing the location of thefts and also for implementing applications such as creating a pollination map of the growing area, particularly useful for greenhouse cultivation. It can also be used to detect faults in water pipes when they are suspended from the wire, attached to the stake supporting the wires, or to the trunk of cultivated plants, with the trunk supported by the wire.

[0008] According to certain embodiments, said analyzer is capable of determining said at least one event as a function of at least one characteristic of said signal representing said vibrational wave and of information recorded in at least one storage module of said device, said recorded information associating to an event at least one characteristic of said signal representing said vibrational wave.

[0009] A vibrational wave signal can advantageously be characterized by one or more features that allow one event to be distinguished from another. Features of the vibrational signal include intensity, shape, wavelength, frequency, propagation time, propagation speed, and direction of propagation.

[0010] According to certain embodiments, said analyzer is capable of obtaining said information from a trained model to associate with at least one characteristic of said signal representative of said vibrational wave detected on at least one wire of an area, in particular of a trellised crop, an event relating to the area, in particular to said crop.

[0011] According to some embodiments, the device includes: - a transmitter capable of transmitting to at least one remote device; - said detected event and / or: - an alarm related to said detected event.

[0012] Thus, advantageously, the amount of data transmitted by the device is low and therefore energy-efficient. Furthermore, the device can transmit an alarm, allowing for the rapid alerting of a remote device to a potential problem in the area, particularly concerning the crop, such as theft. The alarm can also be transmitted to a separate remote monitoring system or to a terminal belonging to a supervisor or even the owner of the area, such as a producer or farmer cultivating the crop.

[0013] According to some embodiments, said at least one vibration wave sensor is an accelerometer.

[0014] According to some embodiments, the analyzer is capable of analyzing a signal representative of the vibrational wave of a taut wire.

[0015] According to some embodiments, when the area is a cultivation area, the event is representative of: - a theft of fruit and / or vegetables in the trellised crop, - a lack of pollination of the trellised crop, - a lack of watering of the trellised crop when a watering pipe is associated with the wire, - damage caused to the crops, - a defect in the trellising.

[0016] According to another aspect, the present invention relates to a method for detecting events relating to an area comprising at least one wire, comprising: - An analysis of at least one representative vibration wave signal emitted by at least one wire of said area, in particular a trellised cultivation area, to determine, as a function of said representative vibration wave signal captured, at least one event relating to said area, the vibration wave having been triggered by the event on the wire.

[0017] According to another aspect, the present invention relates to a computer program comprising instructions for executing the steps of the detection process according to any one of the embodiments of this disclosure when said program is executed by a computer.

[0018] According to another aspect, the present invention relates to a computer-readable recording medium on which is recorded a computer program comprising instructions for carrying out the steps of the process according to any one of the embodiments of this disclosure.

[0019] According to another aspect, the present invention relates to the use of an event detection device for an area consisting of a trellised crop according to the present disclosure to detect theft of fruit and / or vegetables from said trellised crop, when said events are related to theft.

[0020] According to another aspect, the present invention relates to the use of an event detection device for an area consisting of a crop trained in trellis form according to the present disclosure to detect a pollination defect in trellised crops, when said events are related to a pollination defect.

[0021] According to another aspect, the present invention relates to an event alert application for an area, said application comprising instructions to: - receive said event or at least information enabling the determination of said event from an event detection method implemented by a device, in particular according to one of the embodiments of this disclosure, the event detection method relating to an area comprising at least one wire, comprising: + an analysis of at least one representative vibration wave signal emitted by at least one wire of said area to determine, based on said representative vibration wave signal received, at least one event relating to said area, the vibration wave having been triggered by the event on the wire; and - generate said alarm from said event or at least said information enabling the determination of said event.

[0022] According to another aspect, the present invention relates to an event alert device on a fenced area, the alert device comprising: - a receiver capable of receiving said event or at least information enabling the determination of said event from an event detection device relating to an area comprising at least one wire, comprising: - an analyzer capable of analyzing at least one signal representative of a vibration wave from a wire of said area to determine, based on said signal representative of vibration wave captured, at least the event relating to said area, the vibration wave having been triggered by the event on the wire and - a generator capable of generating said alarm from said event or at least said information enabling the determination of said event.

[0023] According to another aspect, the present invention relates to a method for alerting an event in an area, the alerting method comprising: receiving said event or at least information enabling the determination of said event; an event detection method implemented by an event detection device relating to an area comprising at least one wire; the event detection method relating to an area comprising at least one wire, comprising: analyzing at least one representative vibration wave signal emitted by at least one wire of said area to determine, based on said representative vibration wave signal received, at least one event relating to said area, the vibration wave having been triggered by the event on the wire; and generating said alarm from said event or at least said information enabling the determination of said event.

[0024] According to another aspect, the present invention relates to a program comprising program code instructions for executing the steps of the alerting method according to this disclosure when said program is executed by a processor.

[0025] Other features and advantages of the present invention will become apparent from the description given below, with reference to the accompanying drawings which illustrate examples of implementation, without any limiting character.

[0026] In these drawings, from one figure to another, identical elements (or parts of elements) are identified by the same reference symbols.

[0027] Lare represents an example of a trellised zone comprising a system according to an embodiment of the invention.

[0028] Lare represents a method of implementing a functional architecture of a device according to the invention,

[0029] Lare represents a method of embodying the hardware architecture of a device according to the invention,

[0030] This illustrates an example of vibrational waves corresponding to a detected event,

[0031] Lare represents an embodiment of a process according to the invention.

[0032] To make the explanation more concrete, an example of a system implementing event detection in areas containing a wire, particularly trellised crops, is described in detail below, with reference to the accompanying drawings. It should be noted that the invention is not limited to this example.

[0033] Lare represents a schematic view of an example environment implementing the invention.

[0034] The area shown in the figure represents an example of a trellised cultivation system schematically. A key principle of trellised cultivation is growing plants in spaced rows; a single row of trellised plants is shown in the figure. Trellising involves supporting plants (trees, vines, grapevines, etc.) so that they can produce a maximum of fruit without breaking under the weight of the fruit, a phenomenon potentially exacerbated by climatic conditions (wind, rain, snow on green foliage).

[0035] The plants are planted at intervals, aligned along these rows. A trellised cultivation system includes at least two end posts, P1 and Pn, located at each end of a row. Depending on the size of the field or greenhouse where the crop is grown, several rows may be present, and each row may contain a number n of posts, which can vary depending on the row length and the type of plants being cultivated. Generally, these two end posts are anchored in the ground using two anchoring wires or cables, FA and FA', ensuring their secure fixing and thus providing stability to the entire row. Between posts P1 and Pn, a number of row posts, Pi, are placed. These Pi posts are driven firmly into the ground, set in concrete (for example), or placed in concrete footings. These posts can also be made of wood.These stakes are spaced, generally at roughly regular intervals, and the spacing between the stakes may depend on the type of plants, their weight for example. The stakes in row Pi are generally planted vertically in relation to the ground, and the head stakes P1 and Pn are generally angled from the vertical.

[0036] The end posts ensure that at least one wire running the length of each row, between the two end posts, is kept under mechanical tension. The row posts ensure the row is aligned laterally and vertically.

[0037] At least one wire is stretched between the top posts. This wire, called the support wire (FP), is generally located at the bottom and remains in place throughout the growing season, from planting to harvest. Its role is to support the crop and therefore bear most of the weight of the plants. Support wires are usually made of galvanized steel due to the elasticity and durability required. Depending on the crop, several types of support wires may be used.

[0038] One or more FR lifting wires may also be present, stretched between the end posts and positioned higher and roughly parallel to the main wire. The lifting wires can be installed as the plants grow. Both the main wires and the lifting wires are attached, preferably in a removable manner, to the end posts and the row posts. They may be made of, but are not limited to, steel, stainless steel, or synthetic fibers.

[0039] The row stakes allow both the sliding of the wires for a tension distributed evenly along the rows, but also different height adjustments of the FR lifting wires for crops using lifting wires which can be left on the ground during the winter before allowing the annual foliar developments to be raised and maintained at a height (e.g. vine shoots).

[0040] The example of la can be generalized to any areas containing a wire, especially a taut wire, for example a livestock area surrounded by a wire or even a fence, or more generally a piece of land surrounded by a fence.

[0041] In one embodiment, at least one vibration wave sensor C1 is arranged on the support wire. In some embodiments, several vibration wave sensors can be arranged on the support wire, for example, between each stake or between certain stakes. In some embodiments, one or more vibration wave sensors can also be arranged on one or more lifting wires, at one or more locations on the lifting wires. The sensors can also be attached to the stakes or mooring cables as required.

[0042] In some embodiments, the sensors can be devices known as microelectromechanical systems (MEMS). Thus, the detection device using such sensors is very small and inexpensive, advantageously allowing for the low-cost multiplication of observation devices.

[0043] Sensor 1 is preferably powered by batteries. It can also be powered by solar energy (small solar panels for example) or generate its own energy from vibrations.

[0044] According to some embodiments, sensor C1 is an accelerometer.

[0045] It is worth recalling that an accelerometer can determine the direction in which a wire is moving, based on acceleration along one or more axes. In one embodiment, the sensor C1 according to the invention comprises up to three accelerometers detecting linear accelerations of the wire along three orthogonal axes. In another embodiment, the detection modules according to the invention include up to three accelerometers detecting linear accelerations of the wire along three orthogonal axes. The analysis of vibration signals also allows for the interpretation of voltage variations in the wires.

[0046] According to some embodiments, the C1 sensor can be a piezoelectric element.

[0047] According to some embodiments, the sensor can also be composed of gyroscopes with up to three orthogonal axes.

[0048] The C1 sensor is configured to transmit at least one signal representative of at least one vibration wave emitted by at least one wire of said area, in this case of the trellised crop in the example of the.

[0049] A detection device 1 according to an embodiment of the invention is disposed, for example, in the vicinity of sensor C1 (or sensors C1). By proximity, it is understood that the device 1 can receive a signal representative of at least one vibrational wave emitted by at least one wire of said trellised crop originating from sensor C1.

[0050] According to some embodiments, the sensor C1 and the device 1 include a LoRa or NB-IoT or 5G type interface, to transmit (respectively receive) the representative signals of vibration wave.

[0051] Device 1, being small in size, can be easily concealed in or near areas, particularly crops, thus remaining invisible and preventing theft or disabling. The C1 sensor(s) are also small and therefore only visible when close to the wires. Furthermore, as plants grow, they are generally hidden by vegetation such as leaves and fruit on trellises.

[0052] In one embodiment, the sensor c1 is directly integrated into a stake.

[0053] Lare represents a mode of realization of a functional architecture of device 1.

[0054] Device 1 is configured to analyze at least one representative vibration wave signal emitted by at least one wire of the area, in particular of the trellised crop, to determine, based on the representative vibration wave signal captured, at least one event relating to the area, in particular to the crop.

[0055] Device 1 is preferably powered by batteries, but it can also be powered by solar energy (e.g., small solar panels).

[0056] Device 1 therefore preferably includes an analyzer, configured to analyze at least one signal emitted by at least one sensor C1 and received by a receiver or a receiving interface.

[0057] Device 1 may also include one or more storage means, STK, configured to record at least a portion of the representative vibration wave signals.

[0058] The analyzer can detect a plurality of events from the received signals.

[0059] STK storage means may also include data associating to at least one event one or more values ​​of one or more characteristics of the vibration signal or one or more graphical representations of signals representative of a vibration wave, as shown in Figures 4. Thus the storage means may include a list of events and associate to each event, a value or a range of values ​​per characteristic or for certain characteristics or a graphical representation representative of the event.

[0060] Characteristics of a vibration signal include intensity, shape, wavelength, frequency, propagation time, propagation speed, and propagation direction. Several sensors can be used to measure these different parameters.

[0061] In other words, for a given event, one or more data points, in the form of values ​​or ranges of values ​​or graphical representation, can be associated or matched.

[0062] This correspondence can be obtained during system testing or development phases and stored in the storage devices. This correspondence, or lookup table, can be downloaded to device 1 via the transmission interface or transmitter.

[0063] An example of graphical representations of a vibrational wave is presented by the.

[0064] The analyzer analyzes the signals received by the receiver and determines an event from these signals.

[0065] To do this, according to a first embodiment, the analyzer compares the received vibration waves or at least certain characteristics of the received vibration waves with the recorded data associating to at least one event one or more values ​​of one or more characteristics of the vibration signal or one or more graphical representations of signals representative of a vibration wave.

[0066] This comparison can enable the identification of an event within the area, particularly in trellised crops. This comparison can also be associated with a confidence score for the detected event, which can also be transmitted along with the detected event.

[0067] In some embodiments, image capture means can be triggered when an event is detected. This triggering can also be linked to the confidence score associated with the detected event. The image capture means, not shown, can communicate with device 1 wirelessly. The image capture means can, for example, be located on the end posts or on a row post, a dedicated mast, a building, etc. Image capture can be triggered, for example, when the confidence threshold associated with the detection of an event, such as theft in certain areas, particularly in crops, is high. Conversely, the capture means can be triggered when the confidence threshold is low to eliminate false positives.

[0068] In some embodiments, the analyzer includes a trained learning model configured to classify a signal representative of a vibration wave according to an event type. In this embodiment, data or graphical representations representing the events are not necessarily stored in the storage means. The representative data of the vibration wave received from sensor C1 are fed into the trained learning model, and the model outputs an event representative of the vibration wave data given as input to the model. A confidence score can also be associated with this event. Similarly, the capture means can be triggered, as described above, based on the confidence score.

[0069] Among the detected events were: theft in the area, including crop theft; irrigation system failure; pollinator detected in the row; damage to the area, particularly to crops; and trellising defects.

[0070] Damage to areas, particularly to crops, can be caused by weather elements (wind, hail), by wild animals (birds, wild boars, etc.), by humans (accidents, deliberate damage).

[0071] In the case of cultivation areas, trellising defects can be related to verticality, excessive or insufficient wire tension, and breakage of trellising elements.

[0072] Parameters can also be associated with the event to refine its characterization. For example, when several sensors Ci communicate with device 1, a reference or location (e.g., row number in the plot, GPS location) of the sensor can be transmitted, or the time the event was detected. The sensor(s) C1 transmit the captured data to device 1 in the form of signals representing a vibration wave.

[0073] Device 1 may also include a transmission interface or transmitter, configured to transmit to a remote device: - all or part of the signal and / or - said detected event and / or: - an alarm related to said detected event.

[0074] The transmission interface or transmitter can also receive data from a remote system. The transmission interface is preferably a 5G type interface.

[0075] The transmission interface can forward events to a remote device. It is advantageous for the analysis to be performed at device 1 rather than remotely to reduce the amount of data transmitted through the interface, and thus reduce the energy consumed by transmitting a large volume of data.

[0076] In some embodiments, a selection of these events can be transmitted via the transmission interface. The selection can also be made remotely, for example, configured according to the use of device 1.

[0077] Selection may be related to events linked to theft or degradation of areas, particularly crops.

[0078] Selection may be a selection related to events linked to a crop irrigation problem in the case of a cultivation area.

[0079] Indeed, water pipes (or conduits) are sometimes attached to the support wire, these water pipes being regularly pierced to allow individual irrigation of each plant of the trellised crop in the case of a cultivation area.

[0080] The presence of the pipe naturally alters the vibration waves generated by the carrier wire. Therefore, data representing the vibration waves associated with events, in the presence of a pipe on the wire, are also recorded in the STK storage system. When the analyzer is based on a trained learning model, this model is trained to detect events on a wire to which a pipe is attached.

[0081] Detecting a problem related to a water pipe failure might involve, for example, detecting an issue such as overpressure, a blockage, or a hole in the pipe. All of these factors alter the tension on the wire and therefore the characteristics of its vibrational waves.

[0082] Selection can be based on the detection of pollinating insects on crops within a specific growing area. In this pollination-related application, the analyzer can create a pollinator map by analyzing data over a given period. Indeed, detecting a single pollinator on a row may not be sufficient. Providing a map of pollinator presence may be more relevant. Representative data of the vibrational waves associated with the presence of a pollinating insect on a wire are first obtained and recorded in the MEM recording devices. When the analyzer is based on a trained machine learning model, this model is trained to detect pollinating insects on a wire within a row of trellised crops.

[0083] To this end, device 1 is configured to: - analyze at least one representative vibration wave signal emitted by at least one wire in the area to determine, based on the representative vibration wave signal captured, at least one event relating to the area, - said event being related to the detection of a pollinating insect on at least one wire when the area is a crop area, - establish a map of the presence of pollinating insects in the crop from the detection of the event.

[0084] According to some embodiments, several devices 1 can be placed in the same area, in particular the same trellised crop, for example in the same plot or in the same greenhouse and one of these modules can centralize the data analyzed by each module and transmit them via its transmission interface.

[0085] In the described embodiment of the, device 1 has the hardware architecture of a computer, as illustrated in.

[0086] The architecture of a device 1 includes in particular a processor (computing unit) 10, a random access memory 11, a read-only memory 12, a non-volatile flash memory 14 in a particular embodiment of the invention, as well as communication means 13. Such means are known per se and are not described in more detail here.

[0087] The read-only memory 12 of device C1 according to the invention constitutes a storage medium in accordance with the invention, readable by the processor 10, and on which a computer program Prog in accordance with the invention is stored. The read-only memory 12 may also include the trained learning model.

[0088] Memory 14 of device C1 allows for the recording of variables used for the execution of the process steps according to any of the embodiments of this disclosure.

[0089] The computer program Prog defines functional and software modules, configured here to participate in the detection of events related to an area containing at least one wire. These functional modules rely on and / or control the hardware elements 7-11 of the C1 device described previously.

[0090] Lare represents an embodiment of a process according to this disclosure.

[0091] During step E1, device 1 obtains data or graphical representations of vibrational waves associated with events. As mentioned previously, this data may include a value or a range of values ​​per characteristic or for certain characteristics, or a graphical representation of the event.

[0092] Characteristics of a vibrational signal include intensity, shape, wavelength, frequency, propagation time, propagation speed, and propagation direction.

[0093] In other words, for a given event, one or more data points, in the form of values, ranges of values, or graphical representations, can be associated or mapped. For example, non-volatile flash memory 14 can contain representations of vibrational waves as shown in Figures 4, as described previously.

[0094] According to some embodiments, during step E1, the device obtains a trained learning model to determine an event from a vibration wave analysis as described above.

[0095] It can be noted that step E1 can be carried out prior to the implementation of device 1 in the area, particularly in trellised cultivation.

[0096] During a step E2, the device 1 (its receiver) obtains data representative of vibration waves from one or more sensors C1. The data can be received regularly or continuously.

[0097] During an E3 step, device 1 (the analyzer) analyzes the received data, the different analysis modes described in reference to being implemented during the E3 step.

[0098] If an event is detected during step E4, then we proceed to step E5, otherwise we proceed to step E2, i.e., we continue the analysis of the received data.

[0099] During step E4, it may be possible, for example, to select or filter only certain events. The selection (filtering) can be linked to an application or use of device 1. The selection can, for example, be made following information received via the transmission interface from a remote device. Device 1 can select one or more events of interest based on the information received, which may relate to a use of the system. As mentioned, the use could be related to the detection of theft in the area, particularly in trellised crops, the detection of a pollination problem in the crop area, particularly in trellised crops, or the detection of an irrigation problem in the crop area, particularly in trellised crops, among other things.

[0100] If one or more detected events are selected during step E4, then during step E5, one or more pieces of information relating to the detected event are transmitted to a remote device. This information can be transmitted as is or as an alarm. For example, this information can be received on a terminal belonging to a farmer or producer, or directly from area alarm providers, particularly those specializing in crop zones.

[0101] Following step E5, the process loops back to step E2. However, it should be noted that the data acquisition and analysis carried out during steps E2 and E3 are performed continuously and not stopped during step E4.

[0102] Thus, the event detection device relating to an area containing at least one wire can be used to detect theft of fruit and / or vegetables from the trellised crop, when the events are related to a theft and the area is a trellised crop area.

[0103] Thus, the device for detecting events relating to an area containing at least one wire can be used to detect a pollination defect in trellised crops, when said events are related to a pollination defect and the area is a trellised crop area.

[0104] Following step E5, other optional steps can be implemented, such as generating an alert based on the event or at least on the information needed to identify the event. For example, an alert can be generated when a theft, an irrigation system failure, a pollination problem, or any event of interest to a system user or someone who has subscribed to an alarm receiving application is detected.

[0105] The present invention thus relates to an application for alerting an event on an area containing a wire, in particular a trellised crop, said application being capable of receiving from a detection device according to one of the embodiments of this disclosure, said event or at least information enabling the determination of said event and of generating an alarm from the event or at least from said information enabling the determination of the event.

[0106] This disclosure relates to an event alerting device for an area containing a wire, including a trellised crop, the alerting device comprising: - a receiver capable of receiving from an event detection device relating to an area containing at least one wire, said event or at least information enabling the determination of said event and - a generator capable of generating said alarm from said event or at least said information enabling the determination of said event.

[0107] The present invention relates to a method for alerting to an event in an area containing a wire, in particular a trellised crop, the alerting method comprising: receiving from an event detection device relating to an area containing at least one wire, said event or at least information enabling the determination of said event and generating said alarm from said event or at least said information enabling the determination of said event.

[0108] The present invention relates to a program comprising program code instructions for executing the steps of the alerting method according to this disclosure when said program is executed by a processor.

[0109] Although the present invention has been described with reference to specific embodiments, it is evident that modifications and changes can be made to these examples without departing from the general scope of the invention as defined by the claims. In particular, individual features of the various embodiments illustrated / mentioned can be combined in additional embodiments. Therefore, the description and drawings should be considered in an illustrative rather than restrictive sense.

[0110] It is also evident that all the characteristics described with reference to a process are transposable, alone or in combination, to a device, and conversely, all the characteristics described with reference to a device are transposable, alone or in combination, to a process.
