This invention is particularly applicable in the breeding of cattle.

STATE OF THE ART

Animals, especially farm animals, need to drink a certain amount of water per day. For example, a dairy cow needs to drink one hundred liters of water a day. If the animal does not drink enough water, its health can be affected. In addition, for farm animals, and in particular for dairy animals such as dairy cows, water stress caused by insufficient watering lowers animal performance.

Thirty percent of dairy cows have been shown not to drink the hundred liters of water they normally need.

Currently, there are no solutions to control that animals drink the amount of water they need.

For example in farms, in order to verify that each animal is drinking properly, it is necessary that the breeder visually monitors each animal individually to control the amount of water drunk during the day. Such surveillance of farm animals is impractical, especially in farms with large numbers of animals.

DESCRIPTION OF THE INVENTION

Together for monitoring the watering of an animal

As shown in FIG. 1, a set 1 for monitoring the watering of an animal, in particular a farm animal such as a cattle, comprises:

• a device 2 for detecting that the animal is drinking, in particular by acquiring the sound signal generated by the animal over time, so as to acquire at least one sequence corresponding to one or more swallowing noises generated by said animal when it is drinking;

• a processing unit 3 in wired or non-wired connection with the device 2 and configured to implement a process for monitoring the watering of an animal which will be described below using the data measured by said device 2.

Advantageously, the assembly 1 comprises a user interface station 4 which is in wired or non-wired connection with the processing unit 3. Such a user interface station 4 allows a user, such as a breeder, to monitor the animal's watering, and configure the detection process. It can be a touch pad, a smart phone (smartphone), or a keyboard associated with a screen.

The animal watering monitoring process which will be described in detail below makes it possible to measure the amount of water drunk by the animal. Optionally, the method also makes it possible to warn the user that the animal is not drinking enough water, or is drinking too much water.

Furthermore, a set 1 can include several devices 2 associated with the same treatment unit 3 in order to monitor the watering of several animals in parallel.

Device for monitoring the watering of an animal

As shown in FIG. 1, according to a possible embodiment, the device 2 comprises:

- A fastening system 21 for attaching said device 2 to the neck of the animal;

- a microphone 22 which is configured to acquire a sound signal generated by the animal, and thus acquire at least one swallowing sequence generated by the animal when the latter is drinking;

a transmission module 23 which is connected to the microphone 22 and which is configured to transmit to a reception module 33 of the processing unit 3 of the assembly 1 said swallowing sequence (s) acquired by said microphone 22.

According to a possible variant, as illustrated in FIG. 1, the device 2 is a collar comprising a housing 20 inside which the microphone 22 and the transmission module 23 are arranged.

The fact that the device 2 is a collar makes it easy to attach said device 2 to the neck of the animal so that the microphone 22 is located near said neck of the animal, so that the microphone 22 can more clearly acquire the swallowing sounds of the animal. However, other fastening systems 21 allowing the microphone 22 to be placed against the animal's neck can be used.

The transmission module 23 can be a wired transmission module, or a wireless transmission module such as for example a wifi transmission module or a Bluethooth® transmission module.

The microphone 22 is configured to acquire the noise generated by the animal during the day, and thus acquire the swallowing noise that the animal generates when it drinks. When a swallowing noise is picked up by the microphone 22, the animal is considered to be drinking. The microphone 22 can for example be a dynamic coil microphone, a piezoelectric microphone or a surface acoustic wave filter.

In the case where the assembly 1 comprises several devices 2 installed on different animals, each of the devices 2 can have an identifier making it possible to distinguish it from the other devices 2, and thus individually identify the level of watering for each of the animals.

The device 2 can also include means 24 for locating said device 2, in order to be able to locate the animal on which said device 2 is installed. These localization means 24 make it possible to refine the control of the watering of the animal by not counting the watering noises detected by the microphone 22 in the calculation of the water drunk by the animal only when said animal is located at a previously localized drinking point. The animal is considered to be located at the watering point, and therefore likely to be drinking, when the distance between the position of the animal and the position of the watering point is less than a threshold distance.

Preferably, the location means 24 comprise an Ultra Wide Band tag (or UWB for Ultra WideBand according to the well-known English terminology). Such locating means 24 allow great accuracy in locating the device 2 relative to the previously localized drinking point. In addition, the Ultra Wide Band tag makes it possible to measure the altitude at which device 2 is located, and therefore makes it possible to detect when the animal lowers its head. Detecting when the animal lowers its head improves the accuracy of the calculation of the water drunk by the animal because it is considered that the animal drinks only when the animal lowers its head. Thus, drinking noises are only taken into account when it is detected that the animal lowers its head. Other localization means 24 making it possible to acquire the posture of the animal, and in particular the position of the head of said animal, can be used.

Processing unit

As shown in FIG. 1, according to a possible embodiment, the processing unit 3 comprises a processor 31 and a memory 32 configured to implement the method for monitoring the watering of an animal. The processing unit 3 can be located remotely from the device 2. The processing unit 3 can be, for example, in a city or country different from the city or country in which the device or devices 2 are located.

In order to be in connection with the device 2, the processing unit 3 comprises a reception module 33 which is configured to be in connection with the transmission module 24 of the device, so that the sound signal acquired by the microphone 22 of the device 2 is transmitted to said processing unit 3. Thus, the reception module 33 can be a wired, or wireless reception module such as for example wifi or Bluetooth®.

The processing unit 3 can also include a transmission module 34 which is configured to transmit information to the user interface station 4. The transmission module 34 notably allows the processing unit to send alerts to the user via the user interface station 4. The user interface station 4 also allows the user to configure the assembly 1, for example by locating one or more watering points so as to be able to check that the animal is located at a watering point. The user interface station 4 also makes it possible to display the position of the animal or animals equipped with the device 2 when the said device 2 comprises locating means 24.

User interface station

The user interface station 4 comprises a screen, for example a computer screen or a telephone screen on which the data transmitted to the processing unit 3 by the device 2 are displayed.

The user interface station 4 can be used to display the amount of water drunk by the animal over time.

The user interface station 4 can be linked to the processing unit 3 with a wired connection or a wireless connection via the transmission module 34.

The user interface station 4 can be located at a distance from the processing unit 3 and from the device 2. Thus, it is possible for the farmer to monitor the watering of the animals of his farm without being in the building or the meadow where the animals are located.

Method for monitoring animal watering

In relation to FIG. 2, the method for detecting the awakening of the animal which can be implemented by the assembly 1 comprises the following steps:

• E1: acquisition of a sound signal generated by the animal;

• E2: detection of one or more swallowing noises in the acquired sound signal and of a swallowing sequence defined between the beginning of the first swallowing noise and the end of the last swallowing noise;

• E3: processing of said swallowing sequence comprising a measurement of a duration of the swallowing sequence and a measurement of a swallowing frequency of the animal;

• E4: estimation of a quantity of water drunk by the animal from the duration of the swallowing sequence, the frequency of swallowing, and a predetermined quantity of water drunk with each sip of the animal .

The step E1 of acquiring the sound signal generated by the animal is carried out by the microphone 22 of the device 2 when the device 2 is installed on the animal.

The step E2 of detecting the swallowing noise (s) in the acquired sound signal and of a swallowing sequence defined between the start of the first swallowing noise and the end of the last swallowing noise is carried out by the processing unit 3 which identifies in the sound signal acquired by the microphone 22 the swallowing noise or sounds which are distinguished from other sounds that the animal or its environment can generate. Consecutive or successive swallowing noises make it possible to define a swallowing sequence, between the start of the first swallowing noise and the end of the last swallowing noise. Processing unit 3 identifies such a swallowing sequence. "First swallowing noise" means the first swallowing noise made by the animal in a sequence, or series, of swallowing sounds. "Last swallowing noise" means the last swallowing noise made by the animal in a sequence, or series, of swallowing sounds. By “consecutive” or by “successive”, it is meant that the maximum duration between two swallowing noises is less than 10 seconds, and preferably less than 5 seconds.

The step E3 of processing the swallowing noise is carried out by the processing unit 3. The processing unit 3 measures a duration of the swallowing sequence, that is to say the time interval between the start of the first swallowing and the end of the last swallowing, detected in the sound signal picked up by the microphone 22. In a particular case, the sequence may include a single swallowing. Swallows in a swallowing sequence can have a frequency: the processing unit 3 also measures the swallowing frequency of the animal during the duration of the swallowing sequence. The swallowing frequency corresponds to the number of sips taken by the animal per unit of time during the duration of the swallowing sequence. This frequency can be variable during the duration of the swallowing sequence, in which case the processing unit 3 can calculate the average frequency of swallowing over the duration of the swallowing sequence.

Step E4 of estimating the quantity of water drunk by the animal is carried out by the processing unit 3. The quantity of water drunk is calculated by multiplying the duration of the swallowing sequence with the frequency of swallowing from the animal, and using the assumption that a sip from the animal corresponds to a certain amount of water drunk.

By multiplying the duration of the swallowing sequence with the swallowing frequency of the animal, we actually obtain the number of sips drunk by the animal during this watering sequence. The number of sips drunk by the animal is then multiplied by a predetermined value which corresponds to the predetermined amount of water drunk with each sip by the animal. It has in fact been observed that the quantity of water drunk is substantially identical for each sip for an animal. In addition, it has been found that the amount of water drunk per sip is substantially the same for animals of the same breed.

Thus, according to a possible variant, the user can, for example using the user interface station 4, configure the process for monitoring the watering of animals on his farm by recording in the processing unit 3 the breed of animals from his breeding. In this variant, the quantity of water drunk on each sip by animals of this breed is a data item pre-recorded on the processing unit 3.

According to another possible implementation of the method for monitoring the watering of the animal, as illustrated in FIG. 3, the method can also comprise the following steps:

• E11: location of the animal relative to a previously localized drinking area;

• E21: detection that the animal is located at a distance below a predetermined threshold relative to said watering zone;

step E4 of estimating the amount of water drunk by the animal being implemented only when it is detected that the animal is located at a distance below a predetermined threshold relative to said zone d watering.

The step E11 of locating the animal is carried out by locating the device 2, for example using a GPS tag or an Ultra Wide Band tag (or UWB for Ultra WideBand according to English terminology) integrated into said device 2. By moreover, at least one drinking area is located beforehand by the user by recording the coordinates of said at least one drinking area in the processing unit 3.

The step E21 of detecting that the animal is located at a watering area is carried out by the processing unit 3 which only monitors the position of the animal relative to the at least one watering area. It is considered that the animal is located at the watering zone, and therefore that the animal is able to drink, when the animal is located at a distance below a predetermined threshold relative to said at least a drinking area.

Such an implementation of the method makes it possible to follow the movements of the animal, and thus makes it possible to be able to know if the animal is far from a watering area, the animal therefore being unable to water, or if the animal is located at a watering area, the animal is therefore able to drink.

When the animal is far from a watering area, then any drinking noises picked up by the microphone 22 are ignored because the animal cannot drink, these drinking noises being errors. Thus, the only watering noises picked up by the microphone 22 which are taken into account for step E4 of estimating the amount of water drunk by the animal are the watering noises which occur when the animal is located at a watering area.

Thus, such an implementation of the method makes it possible to improve the accuracy of the estimation of the amount of water drunk by ignoring the erroneous drinking noises.

According to an additional implementation of the method for monitoring the watering of the animal, as illustrated in FIG. 3, the method can also comprise the following steps:

• E12: acquisition of an animal posture;

• E22: detection that the animal has its head down;

step E4 of estimating the amount of water drunk by the animal being implemented only when it is detected that the animal has its head down.

The step E12 of acquiring a posture of the animal can be carried out by measuring the altitude of the device 2 (the distance of the device 2 relative to a reference surface, such as the ground), for example thanks to an Ultra Wide Band (or UWB for Ultra WideBand according to English terminology) tag integrated into said device 2.

An Ultra Wide Band tag also offers the advantage of locating the animal. Thus, when the device 2 is located at an altitude, the animal has the head raised, and when the device 2 is located at a low altitude the animal has the head down.

The step E22 of detecting that the animal lowers its head is carried out by the processing unit which monitors the altitude of the device 2 over time, and therefore the position of the animal's head. Thus, when the position of the head of the animal varies with a decrease in the altitude of the device 2, the device 2 approaching the reference surface, the processing unit 3 detects that the animal lowers the head. In addition, for greater accuracy, it can be considered that the animal with the head bowed only when the altitude of the device 2 is less than a threshold value, that is to say that the distance between the device 2 and a reference surface is less than said threshold value. The threshold value can be adjusted according to the height of the drinker.

Such an implementation of the method makes it possible to know when the animal makes the gesture of lowering the head to drink. Thus, when the animal has its head held high, and therefore is not able to drink, the process does not take into account the noises of watering for the estimation of the quantity of water drunk, these noises being wrong. Only the watering noises picked up by the microphone 22 when the animal is in the position to drink, in other words with its head bowed, are taken into account to estimate the amount of water drunk by the animal.

Thus, such an implementation of the method makes it possible to improve the accuracy of the estimation of the amount of water drunk by not taking into account the erroneous swallowing noises.

Advantageously, the implementations of the method which are illustrated in FIGS. 3 and 4 can be combined in order to obtain an even better precision of the estimation of the amount of water drunk by the animal.

According to an additional implementation illustrated in FIG. 5, the step E2 of detection of the swallowing noise (s) comprises a step E23 of frequency filtering of the swallowing noise (s) and / or of the swallowing sequence in order to filter the noise parasites picked up by the microphone 22 and which are present in the sound signal acquired in step E1. The Applicant has in fact realized that the swallowing noise that the animal makes when it drinks has a different frequency from the other noises that the animal is likely to generate, such as for example friction noises, d '' a cough, a rumination when the animal is a ruminant, a swallowing of solid elements when the animal eats, or an empty swallowing. For a cow, the frequency of swallowing noise during watering is typically less than 15,000 Hz, preferably less than 10,000 Hz, and even more preferably less than 2,000 Hz. Swallowing noise can typically be measured at the io th intercostal of a bovine. The swallowing noise can also vary depending on the type of feeding of the animal: a solid feeding will cause a so-called “bullous” noise, and a liquid feeding will cause a so-called “cascade” noise, having a different characteristic frequency range. noise called "bullous". Such a frequency filtering step E23 makes it possible to improve the detection of the swallowing noise and / or of the swallowing sequence. In addition, this step E23 of frequency filtering makes it possible to improve the quality of the processing of the swallowing sequence by increasing the precision in the measurement of the duration of the swallowing sequence and of the swallowing frequency.

This step E23 of frequency filtering is implemented by the processing unit 3 which applies a frequency filter to the sound signal received from the microphone 22 of the device 2.

This implementation can be advantageously combined with other implementations of the animal watering monitoring process.

According to another possible implementation illustrated in FIG. 6, the step E3 of processing the swallowing sequence comprises a step E31 of processing a swallowing noise in order to determine more precisely the quantity of water drunk during the engorged by the animal during a later stage, in particular during stage E4. The processing of a swallowing noise may comprise a measurement of the duration of the swallowing noise and / or a determination of characteristic (s) representative (s) of the swallowing noise. During a step E31, it is possible, for example, to identify during the swallowing sequence a part of the sound signal corresponding exactly to a swallowing noise, that is to say between the beginning and the end of a noise of swallowing. swallowing. Thus, it is possible to count the number of swallows more precisely, by recognizing the swallowing noises subsequent to a swallowing noise identified by comparison of the characteristics representative of the swallowing noise treated and of the characteristics representative of other swallowing noises. . It is also possible to calculate or measure more precisely the volume drunk by an animal during a swallowing sequence by adjusting the value of a predetermined quantity of water drunk with each sip of the animal at least according to the duration of a swallowing noise and / or characteristic (s) representative (s) of the swallowing noise, determined (s) during step E31.

This step E31 of quantifying at least one sip is implemented by the processing unit 3.

This implementation can advantageously be combined with other implementations of the animal watering monitoring process.

According to an additional implementation illustrated in FIG. 7, the method comprises an alert step E5 in which an alert is generated when the quantity of water drunk by the animal for a predefined duration is less than a threshold quantity previously defined .

This alert step E5 is implemented by the processing unit 3 which measures the amount of water drunk by the animal over time and which generates an alert message when the amount of water drunk drops below a predefined threshold value.

The alert message can for example be sent to the user interface station 4, for example by email, telephone message, or any other electronic message.

This alert step E5 makes it possible to quickly warn the breeder 5 that the animal is not drinking enough.

Furthermore, the alert step E5 can also generate an alert when the quantity of water drunk by the animal exceeds a predetermined threshold value. This variant makes it possible to detect anomalies in the behavior of the animal which may for example be due to a disease.

This implementation can advantageously be combined with other implementations of the animal watering monitoring process.
