Definitions
- the present invention relates to an apparatus for monitoring the motion activity of an animal comprising: sensor means for sensing at least one motion state of the animal; transmission means for transmitting of information to an evaluation station and operatively connected to the sensor means.
- It also relates to a method for monitoring the motion activity of an animal involving sensing of at least one motion state of the animal, and transmitting of information to an evaluation station for processing the information obtained.
- EP-A-0 786 203 describes a motion activity system for determination of the physical condition of domestic animals, such as milking animals, by registering their movements within a predetermined area, such as a milk box.
- the known system including an activity sensor carried by the animal monitored, is based on recording the number of movements registered for one or more steps in a computer.
- the registered number of movements is compared in the computer to corresponding informations for various animals.
- the computer is able to indicate the animals whose number of movements deviates from an average value regarding the number of these movements. Then the indication of deviation is interpreted as a symptom of an abnormal physical condition of the animal, e.g. injuries, diseases, heat, and the like.
- the unit known from the WO 97/24027 is based on registration of the number of activities/movements which, although being reported to the evaluation system in a favourable energy saving way, it can be somewhat difficult with regard to obtain fast results with reference to the actual movements of the animal.
- Still another motion activity system is to be found in US-A-5 183 056 and in EP-A-0 423 394 describing an inductive motion sensor.
- the known sensor is based on a spherical magnetic member movable within an ellipsoid cavity surrounded by an electrical coil. The movement of the magnetic member in the cavity generates various electric signals from the coil depending on the actual position of the magnetic member within the cavity.
- the motion activity system is mainly used for heart pacemakers and also as an anti-theft sensor.
- the known systems mentioned above have to be attached in a rather firm way to the body of the object to be monitored. If the object is an animal free to move within the predetermined area, the signals generated by the systems have to be transmitted by a radio transmitter for evaluation at an evaluation station. This radio transmission also adds to the costs of the systems, each one being in itself rather complicated.
- transponder unit For identification of individual domestic animals it is well-known in art to make use of a transponder unit attached to the animal. Such transponder identificators are described e.g. in US-A-4 510 495, US-A-4 247 758, US-A-4 618 861 and in WO 95/32616.
- transponders are presenting identification information only, but they give in no way any information on the animal movements. Therefore, it is an object of the invention to overcome the drawbacks with the known systems mentioned above for having a more reliable monitoring system being mainly a basic stationary arranged system generating activity informations easy to evaluate at an evaluation station for obtaining of fast and true diagnoses of various states of the animal monitored.
- a sensor means includes an intensity measuring device, the output signals of which represent the animal movements in terms of amplitude, transients and/or rising time and are supplied to said evaluation station comprising a processor for determination of various states of the animal.
- sensed motion states are indications on the movement intensity of the animal in terms of signal amplitude, transients, and/or rising time, said signals being processed at said evaluation station for determination of various states of the animal.
- the object is based on a direct monitoring of the animal within a predetermined animal area by a mainly stationary, basic monitoring system evaluating the amplitude, transients and or rising time of the signals generated.
- a safer and faster system for diagnosing of various states, such as general disturbances, restless, heat, etc. of the animal is obtained.
- said intensity measuring device is an image capturing device observing the animal movements, the images captured by said device being supplied to said evaluation station in form of electrical output signals.
- said intensity measuring device includes a combination of an inductive motion activity sensor worn by the animal being observed and an image capturing device observing the animal movements, the output signals from said activity sensor and said image capturing device being processed at said evaluation station for said determination of the various states of the animal, said states being considered true if both said signal generation means simultaneously indicate pronounced signal values.
- the informations obtained from said two intensity measuring sources i.e. from said inductive sensor and from said image capturing device, are compared to each other resulting in a safe determination of the animal status when both the sources generate coincident signals.
- image capturing device is a basic, mainly stationary device including a video camera, an IR camera or a digital camera.
- electrical signals are generated in an analogues or digital form to be directly usable by said evaluation station preferably including electronics processor means.
- comparator means are comparing the obtained output signals to reference signals stored in a memory for evaluation of intense animal movement indicating particular states of the animal if crossing predetermined threshold values.
- a reference is obtained to normal conditions of the actual animal.
- said intensity measuring device is combined with an identification means worn by the animal, said identification means being in information connection with said evaluation station for identification of the animal actually monitored.
- said identification means being in information connection with said evaluation station for identification of the animal actually monitored.
- the animal just monitored can be identified, which is important when comparing stored individual animal data to data obtained from the captured images.
- said identification means is a transponder being in wireless connection with a transponder receiver, said transponder receiver being electrically connected to said evaluation station.
- output signals from said processor are used as control signals for a milking robot.
- the generated signals, indicative for the animal state may be directly used for actuation of an animal handling devise, such as a milking robot.
- the apparatus and the method according to the present invention it is possible to register all the movements taken by the animal monitored by the basic image capturing device.
- the signal generated one may have informations about the animal's momentanous "mental condition" just by interpretation of the amplitude and/or frequency and/or rising time and/or transients of the signal.
- a signal rich of transients may be interpreted as an animal heat.
- a high frequency signal indicates often an anxious or restless animal while a signal with fast rising time deflections may be an indication of an excited animal.
- a calm and regular running signal having no transients etc. will indicate a harmonious animal.
- the signal evaluated at the evaluation station may be used as a health indicator as such, but it can also be used as a control input for an automatic milking robot or the like.
- Figure 1 illustrates in a simplified manner the image capturing area monitored according to the invention
- Figure 2 illustrates a block diagram for a preferred embodiment of the invention
- Figure 3 illustrates a diagram showing the processed output of the image capturing device registered on a tape presenting samples on different signal indications and interpretations thereof.
- Figure 1 illustrates in a simplified manner the image capturing area 1 being monitored by a stationary basic monitoring device 4 shown in form of a camera device.
- Said camera device 4 generates image signals supplied to an evaluation station 21 ( Figure 2) preferably through electric cables 3.
- An animal 6 to be monitored is wearing a transponder 2 wireless 7 connected to a transponder receiver 22 ( Figure 2) for supplying individual animal identification data to the evaluation station.
- an inductive motion activity sensor 5 is also worn by the animal 6. Also said activity sensor 5 is in wireless communication 9 with the evaluation station through a receiver 23 ( Figure 2) for supplying of signals representing animal movements comparable to those obtained from the camera device 4.
- the inductive device 5, including its wireless transmitter, is attached to the animal body at a suitable position, e.g. on one of its legs as shown.
- the evaluated signals at the evaluation station may be used as a control input to a milking robot 8 shown in Figure 1.
- Fig. lb shows a robot stall with a milking robot 8, a monitoring device 4 and a gate 10 to the robot stall.
- the ⁇ lking robot 8 contains teat cups 13, a valve 11 connected to the teat cups 13 and a pulsator 12 also connected to the teat cups 13.
- the monitoring device 4 is connected to an evaluation station 21 and the gate 10, the teat cups 13, the valve 11 and the pulsator 12 are connected to a control station 14 connected to the evaluation station 21.
- the evaluation station 21 receives signals from the monitoring device 4. The signals are evaluated and then transferred to the control station for controlling of the mil- king robot 8. If the evaluated signal establishes that an abnormal situation has arisen, e.g. that the animal being milked is in a state of panic, the milking operation can be interrupted by control from the control station 14, e.g. by closing the valve 11, stopping the pulsator 12 and detaching the teat cups 13. After this either the gate 10 to the stall is opened up to let the animal out or the milking robot waits for the animal to calm down and then tries to milk again.
- an abnormal situation e.g. that the animal being milked is in a state of panic
- the evaluated signals could also control the feeding of the animal.
- Figure 2 illustrates a block diagram for a preferred embodiment of the invention including a camera device as well as an inductive motion sensor 5. To identify the animal actually monitored also a transponder 2 is used.
- the camera device 4 is the basic monitoring device supplying signals of captured images of the whole animal monitored, or parts thereof. Said signals are supplied through cables 3 to the evaluation station 21. Said supplied signals are processed by the evaluation station 21 for determination of various states of the animal monitored. The evaluation is carried out by investigation of the signals with respect to their amplitude, frequency, transients, and/or rising time as will be discussed further below with respect to Figure 3.
- the camera device 4 may be the only signal source for implementation of the present invention.
- the camera device source is combined with the inductive motion sensor 5 mentioned above.
- a comparator means 24 the information signals obtained from said two intensity measuring sources, i.e. from said inductive sensor 5 and from said camera device 4, are compared to each other resulting in a safe determination of the animal status when both the sources generate coincident signals.
- the transponder signals from the transponder receiver 22 suitably activates said memory device 26. Then, stored individual data for the actual animal is supplied to the comparator means 24 for individual evaluation.
- Resulting evaluation signals are processed in a processor means 25 for different purposes as is indicated in Figure 2.
- the processor means 25 generates control signals for a milking robot 8.
- Other processor generated signals are supplied to a printer device 27 and to a personal computer 28 being programmed to visually describe the resulting animal state.
- Figure 3 illustrates a tape registration, e.g. obtained from the printer 27 shown in Figure 2.
- the registration print shown in Figure 3 is an intensity versus time diagram compressed for illustration purpose only, making it possible to illustrate some possible indications obtainable by the system according to the present invention.
- the first section 31 of the intensity/time diagram shows a calm and regular progress of the signal having a normal amplitude/intensity and a long rising time.
- Such a signal stands for a harmonious animal.
- the second section 32 shown in Figure 3 is a signal characterised by a high amplitude/intensity and a rather fast rising time. This signal indicates an animal being excited.
- the third section 33 of the diagram print is showing a more high frequent signal indicating an anxious or restless animal.
- the fourth section 34 of the diagram shows once more a somewhat regular signal progress similar to the one of section 31, but being rich of transients. Such a signal is interpreted as an animal heat.
- the camera 4 may be arranged above the animal, as shown in figure 1 or on a robot arm of the robot 8.
- the described apparatus and method according to the invention are applicable to all domestic animals, but is preferably related to animals to be milked, such as cows, sheep, goats, buffaloes and horses.
