Description

  The present invention relates to detection of riding behavior of livestock and the like.

  Patent Document 1 describes that a cow's estrus lying or standing state is detected by communication between an RFID tag attached under the cow's abdomen and a reader / writer device installed on the cow bed. . However, because it is installed on the cow bed, it cannot be detected during grazing and the system is large.

  Japanese Patent Application Laid-Open No. H10-228688 describes detecting the riding behavior when a cow is in estrus by tilt detection using an acceleration sensor. However, in the case of an acceleration sensor, a thick belt must be wrapped around the torso of the cow in order to prevent false detection due to the action of shaking the skin due to the approach of an ab or the like, or misalignment of the acceleration sensor, etc. Will become a big burden on the cattle.

  Patent Document 3 describes that a recumbent state and a standing state of an estrus of a cow are detected by an inclination sensor. However, like the acceleration sensor, in order to prevent erroneous detection due to misalignment or the like, a thick belt must be wound around the body of the cow, which increases the size of the apparatus and imposes a heavy burden on the cow.

  Patent Document 4 describes that estrus is detected by detecting the number of steps of a cow using a walking sensor. However, like the acceleration sensor, in order to prevent erroneous detection due to misalignment or the like, a thick belt must be wound around the body of the cow, which increases the size of the apparatus and imposes a heavy burden on the cow.

  Patent Document 5 describes that estrus is detected by detecting the amount of cattle activity using a motion sensor. However, like the acceleration sensor, in order to prevent erroneous detection due to misalignment or the like, a thick belt must be wound around the body of the cow, which increases the size of the apparatus and imposes a heavy burden on the cow.

  Patent Document 6 describes that the estrus is detected by detecting the walking distance of the cow using a reader / writer device installed in the barn and a cow with a tag such as RFID. However, it cannot be detected when grazing, and its use is limited.

  Patent Document 7 describes that the estrus is detected by detecting the motion of the cow with a motion sensor and a transmitter that transmits a signal from the motion sensor. However, like the acceleration sensor, in order to prevent erroneous detection due to misalignment or the like, a thick belt must be wound around the body of the cow, which increases the size of the apparatus and imposes a heavy burden on the cow.

  Patent Document 8 describes that estrus is detected by detecting the number of steps of a cow using a walking sensor. However, like the acceleration sensor, in order to prevent erroneous detection due to misalignment or the like, a thick belt must be wound around the body of the cow, which increases the size of the apparatus and imposes a heavy burden on the cow.

  Patent Document 9 describes that estrus is detected by detecting the amount of cattle activity using a vibration sensor. However, like the acceleration sensor, in order to prevent erroneous detection due to misalignment or the like, a thick belt must be wound around the body of the cow, which increases the size of the apparatus and imposes a heavy burden on the cow.

  Patent Document 10 describes that estrus is detected by detecting the number of steps of a cow using a walking sensor. However, like the acceleration sensor, in order to prevent erroneous detection due to misalignment or the like, a thick belt must be wound around the body of the cow, which increases the size of the apparatus and imposes a heavy burden on the cow.

  Patent Document 11 describes that estrus is detected by detecting the riding behavior of a cow with a pressure sensor attached to the waist of the cow. However, it is not possible to determine which cow is riding.

  Patent Document 12 describes that estrus is detected by detecting the riding behavior of a cow with a pressure-responsive switch attached on the spine of the cow. However, it is not possible to determine which cow is riding.

  Patent Document 13 describes the structure of a detector mounting tool for detecting cow riding behavior with a pressure sensor attached to the cow's spine. However, it is not possible to determine which cow is riding.

  Patent Document 14 describes that when a cow's riding behavior is detected by a pressure sensor attached to the cow, notification by light is performed. However, it is not possible to determine which cow is riding.

  Patent Document 15 describes the structure of a detector mounting tool for detecting the riding behavior of a cow by means of an acceleration sensor or an inclination sensor attached to the cow's spine. However, in order to prevent misdetection due to misalignment or the like, a thick belt must be wound around the cow's torso, which increases the size of the device and imposes a heavy burden on the cow.

  Patent Document 16 describes that a recumbent state and a standing state of a cow are detected by a temperature sensor that detects a cow bed temperature. However, because it is installed on the cow bed, it cannot be detected during grazing and the system is large.

  Patent Document 17 describes that the estrus of a cow is detected by a temperature sensor that detects the vaginal temperature of the cow. However, the measurement of vaginal temperature is not possible during grazing, so the use is limited.

  In Patent Document 18, ultrasonic waves from an ultrasonic transmitter attached to the neck of one cow are transmitted to an ultrasonic receiver attached to the neck of the other cow, and ultrasonic waves are transmitted from the ultrasonic receiver attached to the neck of the other cow. Is received, the number of times of reception is counted as it is as the number of times of riding (the number of rides). It also describes using electromagnetic waves or infrared rays instead of ultrasonic waves. However, it is extremely difficult to make the direction in which the ultrasonic receiver attached to the neck of the cattle cow can receive and the direction of transmission of the ultrasonic oscillator attached to the neck of the cattle cow match well. In particular, when riding, the riding cow is in a posture where his head is lowered and his chin is placed on the back of the riding cow. Therefore, the chin of the riding cattle blocks directional signals such as ultrasonic waves. In addition, when riding, the cattle cow often rolls his back and lowers his neck. For this reason, the ultrasonic receiver is hidden behind the back of the cochlea and cannot receive signals with high directivity such as ultrasonic waves.

  Embodiments of the present invention will be described below with reference to the drawings showing various examples. As long as these examples do not contradict each other, the examples can be applied to each other and can be converted. Or as long as there is no contradiction, various technologies can be added and converted.

  FIG. 1 shows an outline of a detection system as a use example. Here, the riding side device 10 is attached to the throat and neck of the cow riding, and one riding side device 20 is attached to the back of the cow on the side where the riding is carried. The boarding side device 10 periodically transmits electromagnetic waves. When the boarding side device 20 faces the riding side device 10 within an appropriate distance, for example, within 0 to 30 cm, the transmission signal received from the riding side device 10 is used as a trigger (or the energy is obtained from the transmission signal). ), And returns the unique ID of the cattle that have been ridden, stored in the to-be-riding side device 20, to the riding side device 10. In riding behavior, the throat, neck, and thoracic area of the cow that is riding and the buttocks, heel, and tail (not including the neck and throat) that are behind and behind the cow Since it often faces directly (including the case where it actually contacts) in this specification, for example, it is preferable to attach it at such a directly facing position.

  Alternatively, an estrus female cow may perform an action of placing his / her chin on the back, buttocks, heel, etc. of another cow (a chin-mounting action). Also in this case, it is confirmed that the riding-side device 10 placed near the bottom of the throat and the neck and the back-side riding-side device 20 face each other and receive a signal from the riding-side device 10 as described above. As a trigger, the unique ID of the cow to be boarded stored in the boarded saddle device 20 is returned to the riding device 10.

  In this way, the unique ID of the cattle that has been boarded is transmitted to the boarding side device 10 of the boarded cow, and the unique ID of the boarded cow is stored in the boarding side device 10 of the boarded cow. In addition, it is possible to detect a cow that has been boarded and a combination of cows that have been boarded. Therefore, for example, an LED attached to the riding-side device detects that the unique ID of the cow involved in the riding behavior (the riding cow or the riding cow) or the combination of the riding behavior cow is detected. The user may be notified by causing the notification unit 14 such as a light to emit light or generating a sound from the notification unit 14 such as a buzzer.

  Next, an example of a schematic configuration of the detection system will be described with reference to FIG. Like the detection system 10 of FIG. 2, the riding side device 10, the to-be-ridden side device 20, and the user side terminal 30 may be provided.

The boarding side apparatus 10 transmits a signal to the boarded saddle side apparatus 20 by the communication system of the first system, and from the boarded side apparatus 20 by the communication system to the first system in response thereto. Receive a reply.
For example, the first method is a communication technology such as (for example, NFC (NFC-A, NFC-B, NFC-F)) technology or a highly directional communication method such as IrDA.

  When the reader / writer device used in the NFC technology is adopted as the first communication method, the rider side device 20 provided with a tag (mainly composed of an antenna and a memory) called a passive RFID tag is used. NFC (NFC-A, NFC-B) that transmits an electromagnetic wave (which may also serve as a return energy source) and receives a signal (reply) from the RFID tag of the rider side device 20 , NFC-F, etc.)), a communication unit 12, a control unit 13, a memory 14 storing a unique ID of a livestock (female cow, calf, horse, pig) to which the riding side device 10 is attached; Second communication for enabling communication between the power source 15 that can employ a battery (secondary battery) or a fuel cell and the user side terminal 30 (when the user side terminal 30 described later is provided). method For example CDMA, LTE, WiFi, it may include a communication unit 16 that conforms to the BlueTooth (registered trademark)). The content of the transmission signal may be a reply request for the unique ID stored in the memory of the rideee side device 20 as a minimum.

  Of course, instead of the NFC technology, IrDA can be adopted as the first method. In this case, the communication unit 12 of the first method may include a light emitting unit and a light receiving unit that emit or receive infrared rays. IrDA is also advantageous in that the communicable distance is longer than NFC (about 30 cm to 1 m). Furthermore, instead of infrared transmission / reception, a laser beam of a pulse wave having a specific wavelength may be transmitted / received.

  NFC, IrDA, and laser light both have a small solid angle with which communication is possible, and the communication units need to be in a state of being close to each other. Therefore, in the present invention, a communication method with high directivity may be employed to reduce the possibility of erroneous detection. In other words, there is a merit in that it is easy to prevent erroneous detection that the communication units communicate with each other without depending on the riding behavior or the chin-mounting behavior.

  The communication unit 12 of the first method of the riding device 10 repeats transmission at an interval of about once per second, for example. Of course, it may be more frequent than 1 second. Then, when a reply is received at the time of transmission once per second, after that, for a certain time or more (for example, 4 seconds or more) from the last reply (a riding time + a certain time or more), 0.1-0. Transmission is repeated at a fine cycle of about once every 3 seconds. This is to accurately measure the riding duration while reducing power consumption when not riding. Of course, the setting of this cycle can be variously changed.

  The second-system communication unit 16 may be compliant with, for example, CDMA, LTE, WiFi, BlueTooth (registered trademark), or the like. The second system is preferably low in directivity and capable of transmitting radio waves from within the pasture to the outside of the pasture. For example, the distance should just exceed about 200 m. If one or more relay base stations are installed in the pasture, the distance may be shorter. For example, it may be about several tens of meters. If you are using an electric fence called an electric fence (usually a high-voltage and low-current pulse wave is applied), add another power line for the relay base station to this fence. .

  The to-be-ridden side device 20 can be configured by a method corresponding to the first method of the riding-side device 10, for example, a tag using NFC technology, and may include a communication unit 21 and a memory 22. The memory 22 only needs to have a unique ID written for each target livestock to be attached. When the previous first method is NFC, the communication unit 21 may employ a tag that can communicate in the RFID communication mode. In this case, a livestock such as a cow is not required in that a power source such as a battery is not required. The structure can be simplified when attached to the back. Of course, a battery may be provided for communication using the power source. When IrDA or pulsed laser light is used as the first method, the communication unit 21 may include a light receiving unit and a light emitting unit corresponding to each. Of course, you may further provide the power supply for the drive of a light emission part.

  The user-side terminal 30 may not necessarily be provided, but if it is provided, convenience is improved. The user terminal 30 may include a power source 31, a control unit 32 (calculation unit 32 ′), a display unit 33, a notification unit 34, a communication unit 35, an operation unit 36, and a memory 37. In addition, the apparatus which can be equipped with these things most easily is what is called PC, a smart phone, a tablet, etc., and the application which can operate | move with these. An outdoor type smartphone that is resistant to water drops, dirt and dust during stable work is preferably used.

  The control unit 32 controls the entire terminal 30 on the user side. In particular, the calculation unit 32 ′ calculates the number of times of riding (riding time) or the number of times of riding (rided time), or these The result of the calculation is compared with each threshold value. This will be described later.

  The display unit 33 may be capable of displaying information such as the number of times of boarding described later, a selection screen for determining whether or not to contact a veterinarian, and a screen when an e-mail or a phone call is received.

  The notification unit 34 may perform notification when the number of times of riding, riding time, etc. exceed a predetermined threshold, or notification when a mail or telephone is received (if these functions are installed). . Various conventionally known methods such as sound, light, vibration, and text display may be employed. In particular, when there is a strong suspicion of cow estrus, when the insemination should be rushed over time after the start of estrus, the user may be notified by a notification mode that has a stronger impact than usual. For example, there is a difference in volume, intensity of light, and the like. Or, normally, only one type of notification, such as sound, may be used, but in an emergency, notification may be performed using a plurality of notification methods such as sound, light, and vibration.

  The communication unit 35 of the second method is preferably one that can communicate with the previous communication unit 16 by a method based on, for example, CDMA, LTE, WiFi, BlueTooth (registered trademark), or some of them.

  The operation unit 36 can employ a technique for receiving various operations such as operation keys and a touch panel.

  For example, the memory 37 may store information related to riding behavior obtained through the communication unit 35 or may be used as a storage area in various arithmetic processes. In addition, the memory 37 has information such as a specific veterinarian or an artificial midwife, a physical condition record of each cow, a past estrus record (for example, a previous or previous estrus record, a record of last fertilization, etc.) ) Etc. may be provided.

  Next, some examples of the structure of the riding device 10 will be described with reference to FIGS. 3 to 5. As shown in FIG. 3, the antenna of the communication unit 12 is arranged inside the waterproof casing 18 as an example in which the first method uses the NFC technology. The antenna may be arranged on the side close to the rided cochlea in the riding behavior. When the first method is IrDA, the light emitting unit and the light receiving unit may also be arranged on the side closer to the to-be-cochlea in the riding behavior. Further, the circuit board 13 may be disposed inside the housing 18 and may constitute a part or all of the control unit 3 and the memory 14. Furthermore, the power supply 15 comprised from a lithium ion etc. is provided, for example. Moreover, the antenna of the communication part 16 of a 2nd system may be arrange | positioned. Although not shown, a display unit, a notification unit, and the like may be provided.

  FIG. 3 shows an example of the structure of the riding device 10. In the example of FIG. 3, a holder 17 is attached to the outside of the housing 18 of the riding side device 10. The holder 17 is, for example, a collar type as shown in FIG. Alternatively, the holder 17 is, for example, a 17 'type with a head as shown in FIG. These materials may be composed of rubber, leather, cloth, ropes, ropes, or the like, which are constituent members such as ordinary livestock heads, and need only have durability and flexibility. It should be noted that, regardless of whether it is the collar 17 or the head strap 17 ′, a mechanism capable of adjusting the length may be adopted, and the length at the time of wearing does not need to be tightened so as to press the neck, and is between the neck Some clearance may be provided. Although not shown in the drawings, it may be a belt or a horse's abdomen so that the front leg is sandwiched from the shoulder.

  In FIG. 4, one rider-side device is arranged, and in FIG. 5, a plurality of rider-side devices are arranged. For example, as shown in FIG. 2, in the case where the rider side device includes a loop antenna and a memory, a so-called NFC chip called a chip of about 3 mm to 1 cm in both length and width may be used. In this case, by arranging a large number of the saddle riding side devices 20 on the back as shown in FIG. 6, it is possible to reduce the fact that no riding can be detected due to a positional shift during riding.

  In FIG. 6, four patterns are shown sequentially from the left side. In the leftmost pattern (1), the rider side devices 20 are arranged on the left and right sides of the backbone of the livestock. Here, the left and right belt-shaped members indicate the holding members 23 that hold the to-be-ridden side device 20. Thus, since it is arrange | positioned not only on the spine but on the right and left, it is easy to detect a chin-riding action. The belt-shaped holding member 23 is made of, for example, cloth or rubber, and may be fixed to the back of the livestock by applying an adhesive, for example. A biocompatible medical adhesive (for example, cyanoacrylate) is preferable, but it only needs to partially adhere to the hair of cows or horses. As it falls off or is collected every 21 days with the cycle of estrus, the adverse effect on livestock of livestock is low regardless of the type of adhesive. In addition, when the to-be-ridden side apparatus 20 is a type which does not use a battery, it does not need to be removed from livestock every time as a detection system. If a battery is required, only the battery may be removed.

  In the leftmost pattern (1) in FIG. 6, six pieces on one side and a total of twelve saddle-side devices on the left and right sides are bonded and fixed to such a holding member 23, and the position of the neck of the livestock that has been boarded It is easy to detect the posture when riding and the variation in the position of the back and chin of the chin ride behavior. In the pattern (2) shown in FIG. 6, the rider side device 20 is mounted, and a covering part made of cloth, rubber, or net covering a wide area of the back, and attached to the right and left of the covering part, The holding member 23 provided with the belt which goes around under is disclosed. In this case, the rider side device can also be arranged on the upper shell portion that hits the spine of the cow. Thus, when the rider side device 20 is arranged on the spine, the rider side device 10 attached to the cow's neck is often arranged in the middle without being biased to the left and right of the livestock, so it is difficult to overlook the riding behavior. it can. Of course, an adhesive may be used in the same manner as the pattern 1 instead of the belt.

  In the pattern (3), the belt-shaped object is arranged so as to extend from side to side so as to straddle the spine. Here, as the material / structure of the holding member 23, an adhesive or a belt can be used as in the patterns (1) and (2). Moreover, the to-be-ridden side apparatus 20 is arrange | positioned along the spine also in the ridge part. As described above, the arrangement at the ridge portion is effective when, for example, a male calf is grazed in the same pasture instead of a grazing land only for female cows. In other words, when the riding side device 10 is attached to a male calf, the height is low, so the calf riding side device 10 may not reach the back shell of a cow capable of giving birth. Therefore, by attaching the to-be-ridden side device 20 around the tail of the female cow and the tail, for example, around the ridge portion, it becomes easy to detect the riding (to-be-ridden) behavior.

  In the pattern (4), the chip-shaped saddle-side device 20 is fixed using an adhesive member 23 made of an adhesive. That is, the holding member 23 may be an adhesive itself. Here, a plurality of the saddle riding side devices 20 are individually attached at positions where they are likely to face the riding side devices 10 such as the back, buttocks, and tail of livestock. Note that the holding member 23 is not only made of an adhesive, but may be one in which a chip is fixed to a thin piece made of acrylic, PET or the like with an adhesive attached to the back surface. In attaching a thin piece made of acrylic or the like to cow's hair or skin, an adhesive may be used on the back side of the thin piece as before. Of course, the holding member 23 may be an adhesive sheet. The chip | tip of the to-be-ridden side apparatus 20 may be affixed on things, such as a bandage and a surgical tape. If it is such, it is easy and simple and the cost can be reduced. In addition, you may make it cover a chip | tip and the adhesive agent after hardening with things like urethane gel. At the time of riding or riding on the chin, the possibility that the to-be-ridden apparatus 20 or the holding member 23 is caught or damaged on the lower abdomen or jaw of the livestock can be reduced. The holding member 23 with such a covering member may be used.

  FIGS. 7 to 12 are examples of display screens that display information on the riding behavior of each domestic animal collected from the riding device 10 on the display unit 33 of the user terminal 30. Using such a screen example, the information on the riding behavior and the algorithm for estrus determination will be sequentially described.

Here, the result of collecting data from 8 o'clock in the morning (start of grazing) to around 9:30 for a plurality of cows in the same pasture is shown. In FIG. 7, the explanation will be made using the cow A in the leftmost bar graph. The number of times that the riding side device 10 of the cow A communicates with the riding side device 20 of the other cow (the number of times of riding communication) and the other cows. And the total number of times the other cow's riding-side device 10 and the cow A's riding-side device 20 communicated with each other (the number of times of the riding-ridden communication) are shown. Here, cow A has the number of norikura communication exceeding the first threshold (40 times). In addition, the number of times of crossed communication exceeds the fourth threshold of 20 times. Here, the determination that the person is in estrus may be a case where the number of times of riding and riding exceeds the first threshold, the number of times of riding and riding exceeds the first threshold, and the number of times of riding and riding is the fourth threshold. May be exceeded.
Next, when looking at the cow D, the cow D has more than 25 times the second threshold, which is the second threshold. In this case, it is determined that the possibility that the cow D is in estrus is high. In the case of cow D, the number of times of boarding and riding communication does not exceed the third threshold, but the number of times of riding and riding communication exceeds the second threshold and the number of times of boarding and riding communication exceeds the third threshold, the estrus It is also possible that there is a high possibility.
Next, with regard to cow C, the number of riding boarding communication does not exceed any threshold value, but the number of riding boarding communication exceeds the third threshold value of 12 times. In this case, it is determined that the possibility of estrus is high. As for cow T, both the number of boarding traffic and the number of boarding car communication do not exceed either threshold, but the number of boarding traffic matches the second threshold, so there is a possibility that it is in estrus. Judgment.

  These bar graphs are designed so that the cow with the highest total number of communications, that is, the cow with the higher probability of being in estrus, is displayed on the left side of the screen. A cow has a comment in the box about the possibility of estrus. Such comments are not essential, and the user may check the estrus based on his own experience and the characteristics of each cow while viewing the bar graph. For cows that are in estrus, the time elapsed from the point at which the possibility of estrus was observed is shown. This is because the elapsed time is displayed from 0 to 24 hours, preferably from 5 to 16 hours, more preferably from 8 to 13 hours from the start of estrus. Furthermore, since it depends on individual differences of cattle, such as whether each threshold value and the number of times of riding and riding communication and the number of times of riding and riding are important, such a determination condition may be set for each user, Furthermore, the user may be able to set conditions for each cow.

  In FIG. 8, using cow A in the leftmost bar graph, the number of times of riding derived from the number of times the riding side device 10 of cow A communicates with the riding side device 20 of other cows, and other The total number of times of boarding derived from the number of times that the boarding side apparatus 10 of the other cow and the boarding side apparatus 20 of the cow A communicated with each other is shown. Here, cow A has a number of times of riding exceeding the first threshold (10 times). In addition, the number of times of crossed communication exceeds the fourth threshold of 7 times. Here, the determination that the person is in estrus may be made when the number of times of riding exceeds the first threshold, or when the number of times of riding exceeds the first threshold and the number of times of riding exceeds the fourth threshold. It is good. That is, the manufacturer or the user may be able to set various determination conditions depending on the breeding environment, individual differences, the type of livestock, and the like.

Next, as for cow D, cow D has exceeded the second threshold of 7 times. In this case, it is determined that the possibility that the cow D is in estrus is high. In the case of cow D, the number of times of boarding does not exceed the third threshold of 4 times, but the number of times of riding exceeds the second threshold and the number of times of riding exceeds the third threshold. The possibility of estrus may be high.
Next, regarding cow C, although the number of times of riding does not exceed any threshold value, the number of times of riding exceeds 4 times which is the third threshold value. In this case, it is determined that the possibility of estrus is high. Regarding cow T, both the number of boarding times and the number of boarding times do not exceed either threshold, but the number of times of riding matches the second threshold value, so it is determined that there is a possibility of being in estrus. Yes.

  Here, in order to determine the estrus by calculating the number of times of boarding (boarding) from the detected number of boarding (boarding) communications, it is possible to calculate based on various algorithms. Examples of operations using some algorithms are described below.

  In cattle riding behavior, the cattle riding on the board continue to ride on the cattle being cattle for an average of about 2 to 8 seconds. Therefore, on average, the riding (riding) duration in one riding action is 2 to 8 seconds.

  For this reason, for example, when there are a plurality of communications between the riding device 10 of the cow A and the riding device 20 of the cow B, a time (for example, 6 seconds) from the first communication to the last communication is obtained. If the previous average duration is within 2 to 8 seconds, the number of times of cattle A's riding may be counted as 1, and the number of times of cattle's riding of cattle B may be counted as 1. In this case, one or a plurality of the riding-side devices 10 for the cow A may be arranged, and one or more the riding-side devices 20 for the cow B may be arranged. That is, the first communication and the last communication may be communication between any of the riding side devices 10 of the cow A and any of the riding devices of the cow B. Specifically, the first communication with the rider's saddle device 20 arranged on the tail of the rider's cochlea B is detected, and after 4 seconds, the rider's saddle device on the back of the rider's cochlea B When there is communication with 20 and there is no communication thereafter, the riding time is 4 seconds, and the number of times of riding (ridden) 1 is counted.

  Or, more simply, when there is a plurality of times of communication between the riding device 10 of the cow A and the riding device 20 of the cow B, the time (for example, 3 seconds) from the first communication to the next communication is first. 1 may be counted in the same manner when the average duration is between 2 seconds and 8 seconds. As long as it is the same cow's saddle rod side device 20, it is the same as long as it communicates with any of the saddle rod side devices 20. Therefore, although the ID given to the rider side device is different for each cow, there is no problem even if the same ID is given to the same cow. For this reason, the writing operation to the memory (RFID chip) of the non-ride-side device 20 is simple.

  On the other hand, for example, when the time until the next communication is outside the range of the previous average duration of 2 to 8 seconds with only the first communication, or when there is only the first communication but there is no next communication The riding behavior may be counted as 0 (zero). However, in this case, the count may be set to 1 in the chin-in behavior. This is because the communication detected by the average chin action is a single or very short span time. Since the chin-in behavior is also an index of estrus, estrus may be determined including these.

  In addition, in the cattle riding behavior, the riding cattle first takes a behavior similar to the chin riding behavior in which the riding cattle put their face on the tail and tail of the cattle cattle. At this time, if there is no sign of estrus in the cattle to be boarded, it may take an action to refrain from riding and escape. In this case, only one communication can be detected. Therefore, the riding number is not counted, and the number of chin-on (chinded) times 1 may be counted. Cattle with a large number of chin rides may be in estrus, but if the number of chin rides is large despite the small number of chin rides, it is likely that boarding is not permitted and estrus is possible. It may be determined that the property is low.

  On the other hand, if the cattle cattle have signs of estrus, the cattle cattle do not move much, even if there are chin-riding behaviors or similar gestures, or allow subsequent cattle riding or During this time, walk forward for a few steps and take a gentle action to escape the ride.

  The Norikura beef takes the same action as the chin-riding behavior, which is the first step of the Norigami behavior, then rises by kicking the ground with the precursor, and at the same time, it rides from the tail side to the head side The cow's body moves forward. Accordingly, in the plurality of saddle rod side devices 20 attached to the same cow, first, communication with the saddle rod side device 20 attached around the tail and tail of the saddle cow is detected, and then the front side Communication with the to-be-ridden side device 20 will be detected. Accordingly, even in the case where the position of the contacted rider-side device 20 in the plurality of rider-side devices 20 moves from the rear to the front, the rider (the rider) ) The number of times may be counted as 1. It should be noted that, when the riding is finished, there is a movement that the body of the boarding cow is displaced to the rear of the boarded cow, and it is also useful as detection of riding. That is, the first contact with the rider-side device 20 arranged on the back and the subsequent contact with the rider-side device arranged on the tail is 1 May be counted as However, if the tail, back, and tail are detected during the previous average ride detection time, the previous average ride detection time is temporarily set so that the number of rides is not counted as 2. Even if there is communication with 3 or more of the rider side devices, 1 is counted so that the count does not become 2 or 3. That is, it does not count twice. When following such an algorithm, the ID assigned to the rider's saddle-side device 20 is different for each cow, and different IDs may be given for each arrangement in the same cow such as the back and tail. For example, when the cows A and B are described in the order of the left side of the back, the spine, and the right side from the caudal side to the head side, the IDs are A-1L, A-2L, A-3L,. -1M, A-2M, A-3M ..., A-1R, A-2R, A-3R ..., cow B, B-1L, B-2L, B-3L ..., B- 1M, B-2M, B-3M,..., B-1R, B-2R, B-3R,.

In FIG. 9, the explanation will be given using the cow A in the leftmost bar graph. The riding time accumulated from the time when the riding side device 10 of the cow A communicates with the riding side device 20 of other cows, and the like. This shows the accumulated riding time derived from the time when the other cow's riding device 10 and the cow A's riding device 20 communicated with each other. Here, cow A has a accumulated time exceeding the first threshold of 60 seconds. In addition, the number of times of crossed communication exceeds the fourth threshold of 20 seconds. Here, the determination that the person is in estrus may be made when the number of times of riding exceeds the first threshold, or when the number of times of riding exceeds the first threshold and the number of times of riding exceeds the fourth threshold. It is good.
Next, regarding the cow D, the cow D has a cumulative riding time exceeding the second threshold of 30 seconds. In this case, it is determined that the possibility that the cow D is in estrus is high. In the case of cow D, the accumulated weight accumulated time does not exceed the third threshold of 15 seconds, but the accumulated weight accumulated time exceeds the second threshold, and the accumulated saddle accumulated time exceeds the third threshold. If it is, the possibility of estrus may be high.
Next, with regard to cow C, the accumulated riding time does not exceed any threshold, but the accumulated riding time exceeds the third threshold of 15 seconds. In this case, it is determined that the possibility of estrus is high. Looking at the cow T, neither the accumulated riding time nor the accumulated riding time exceeds either threshold, but the accumulated riding time is consistent with the second threshold, so there is a possibility that it is in estrus. Judgment.

  Here, various algorithms are used to calculate estrus determination by calculating the riding time (striped) duration time and the riding time (sloped) accumulated time from the detected number of times of riding (sliding race). It is possible to calculate based on this. Examples of operations using some algorithms are described below.

  As described above, on average, the riding (riding) duration in one riding action is 2 to 8 seconds. Therefore, in the simplest case, when there is one or a plurality of communications between 2 seconds and 8 seconds, the center value of the average riding time of 5 seconds may be counted.

  Alternatively, the elapsed time from the first communication to the last communication is counted as a riding (or boarding) duration between 2 seconds and 8 seconds. The accumulated time for each time of the riding (the boarded rod) for a plurality of times of riding is the riding (the boarded rod) accumulated time. That is, it is considered that the greater the accumulated time of riding, the higher the accuracy of estrus, and the higher the accumulated time of riding, the higher the accuracy of estrus.

  On the other hand, for example, when the time until the next communication is outside the range of the previous average duration of 2 to 8 seconds with only the first communication, or when there is only the first communication but there is no next communication The riding duration time may be counted as 0 (zero).

  In addition, in the cattle riding behavior, the riding cattle first takes a behavior similar to the chin riding behavior in which the riding cattle put their face on the tail and tail of the cattle cattle. At this time, if there is no sign of estrus in the cattle to be boarded, it may take an action to refrain from riding and escape. On the other hand, if the cattle cattle have signs of estrus, the cattle cattle do not move much, even if there are chin riding behaviors or similar gestures, During that time, walk a few steps forward and take a gentle action to escape the ride.

  The Norikura beef takes the same action as the chin-riding behavior, which is the first step of the Norigami behavior, then rises by kicking the ground with the precursor, and at the same time, it rides from the tail side to the head side The cow's body moves forward. Accordingly, in the plurality of saddle rod side devices 20 attached to the same cow, first, communication with the saddle rod side device 20 attached around the tail and tail of the saddle cow is detected, and then the front side Communication with the to-be-ridden side device 20 will be detected. Therefore, even in the case where the position of the contacted saddle-side device 20 in the plurality of such saddle-side devices 20 moves from the back to the front, the back-side rider The difference time (3 seconds) between the communication time with the side device 20 (for example, 8:25:00) and the communication time with the front side passenger-side device 20 (for example, 8:25:03) is (Traft) You may count as continuation time.

It should be noted that, when the riding is finished, there is a movement that the body of the riding cow is displaced to the rear of the riding cow, and it is also useful as detection of riding. That is, the communication time (for example, 8:25:00) with the rider-side device 20 arranged on the back that first communicated, and then the communication time (eg, 8 with the rider-side device arranged on the tail). The difference time (4 seconds) from the time 25 minutes 04 seconds may be counted as the riding time. However, if the tail, back, and tail are detected during the previous average Norikura detection time, the communication time from the first tail to the last tail will not be double-counted. The difference between the values may be the riding time.
When following such an algorithm, the ID assigned to the rider's saddle-side device 20 is different for each cow, and different IDs may be given for each arrangement in the same cow such as the back and tail. For example, when the cows A and B are described in the order of the left side of the back, the spine, and the right side from the caudal side to the head side, the IDs are A-1L, A-2L, A-3L,. -1M, A-2M, A-3M ..., A-1R, A-2R, A-3R ..., cow B, B-1L, B-2L, B-3L ..., B- 1M, B-2M, B-3M,..., B-1R, B-2R, B-3R,.

  Next, the example which displays the graph which shows the detail of the estrus action of the cow A is demonstrated using FIG. Here, the details of cow A shown in FIG. 10 may be displayed by touching the bar graph of cow A in FIGS. In this case, the operation unit 36 may be a PC mouse or a touch panel.

  The activity amount of the riding behavior that occurred between 8 o'clock at the measurement start time and 9:30 at the current time is set on the vertical axis, and the time is set on the horizontal axis. The amount of activity is, for example, when the upper side is the above-mentioned number of times of riding / riding communication, and the lower side is the number of times of riding / riding communication described above. Ii) Cumulative time, number of chin rides (over chin ride), etc. may be used. In the case of cattle A, the riding behavior is detected at around 8 o'clock and the riding behavior is seen from around 9 o'clock, so that a remarkable estrus state is exhibited. Since the elapsed time from the start of estrus is about 1.5 h, such a period is suitable for the period of fertilization (for example, from 4 hours to 12 hours of estrus start, more preferably from 6 hours to 10 hours of estrus). What is necessary is just to continue follow-up based on a graph.

  FIG. 11 shows the details of the combination of the communication logs of the riding side and the riding side recorded in the memory of the riding side device 10. This may also be displayed by operating the operation unit 36 of the user side terminal 30. The riding device 10 accumulates riding communication records based on such logs. In this way, every time the Norikura communication log can be taken, log information only needs to be transmitted from the riding side device 10 to the user side terminal 30 via the communication unit of the second method. Note that the log information may be transmitted to the user-side terminal 30 once every 5 minutes or 10 minutes, whether or not there is detection (communication) of riding behavior. Alternatively, the log information may be transmitted by using a single riding action or a certain number of riding actions as a trigger. In this case, it is only necessary to activate the communication unit 16 of the second system when necessary, and a so-called mobile phone or the like does not require a standby state at all times, which contributes to power saving.

  Next, the example which displays the screen which selects the future action with respect to the target cow A is shown using FIG. Here, four actions that are often performed after the estrus is confirmed are displayed as options. That is, (1) whether or not to make an emergency contact with the veterinarian, (2) whether or not to send the riding action information to the veterinarian, (3) whether or not to give an artificial insemination instruction to the veterinarian, ( 4) Whether to continue observation. The contact information of veterinarians in (1) to (3) may be a pre-registered veterinarian's phone number, e-mail address or that of an artificial inseminator, or an employee who has the authority to fertilize in the ranch. It may be. Further, any one of these options may be selected, or a plurality of options may be selected.

In addition, in this specification and a claim, although the boarding side apparatus and the to-be-ridden side apparatus are named, the scope of application of the present invention is not limited to cattle riding. The device on the side on which the chin is placed and the device on the side of the rider include the device on the side on which the cradle is placed and the device on which the chin is placed.
Therefore, the protection range of the present invention includes detection of the previous chin-riding behavior, horse and pig riding behavior, and detection of mating behavior based on the riding detection information. For example, there is a possibility that mating behavior of natural mating can be detected by the riding side device 10 attached to the front of the chest from the neck of the male horse and the riding side device 20 attached to the back of the female horse. The same applies to pigs.
