Description

Method and system for estimating the health status of an object

[0001] The present invention relates to a method and system for estimating the health status of an individual.

[0002] In order to raise livestock such as cows healthily, it is very important to closely monitor the lactation status of the calves.

[0003] If there are only a few pups, monitoring CCTV footage and other means of measuring individual pups' nursing time can be time-consuming and labor-intensive. However, this is practically impossible to observe as the number of pups increases. Therefore, if a pup is nursing, it's difficult to determine in detail whether it's receiving adequate milk.

[0004] For example, even if a farm owner or manager visually observes a cow nursing its young, the cow's nursing time may fall far short of the standard nursing time. Furthermore, even if the cow has sufficient nursing time, if the mother's milk production is insufficient, the cow may not be receiving adequate milk.

[0005] Specifically, there may be cases where the mother is unable to nurse sufficiently due to health issues of the calf (if the calf does not have enough nursing time), or there may be cases where the calf is willing and energetic to nurse but the mother does not have enough milk (if the calf is willing and energetic to nurse but the mother does not produce much milk).

[0006] In particular, in the case of Korean cattle, since it is a breed that lacks milk among meat cattle, it is possible to select individuals to be culled as breeding cattle by estimating the amount of milk produced by the mother by analyzing the lactation pattern of the calves.

[0007] Accordingly, the inventor(s) of the present invention propose a technique for estimating the amount of milk produced by a mother by analyzing the maternal behavior pattern, and estimating the health status of the mother and / or offspring and the milk intake level of the offspring.

[0008] The purpose of the present invention is to solve all of the problems of the above-mentioned prior art.

[0009] In addition, the present invention is a method for estimating the health status of an individual, the method comprising: obtaining information on at least one of a mother and a baby; and estimating the health status of at least one of the mother and the baby by referring to the information on the baby.

[0010] In addition, the present invention has another purpose of estimating the amount of milk produced by a mother by analyzing the lactation behavior pattern of the individual, and estimating the health status of the mother and / or offspring and the milk intake level of the offspring.

[0011] In addition, another purpose of the present invention is to efficiently manage an individual by quickly and accurately determining the health status of the individual and providing information necessary for raising the individual appropriately and in a timely manner based on the health status of the individual.

[0012] A representative configuration of the present invention to achieve the above purpose is as follows.

[0013] According to one aspect of the present invention, a method for estimating the health status of an individual is provided, comprising the steps of: obtaining information about at least one of a mother and a baby; and estimating the health status of at least one of the mother and the baby by referring to the information about the baby.

[0014] According to another aspect of the present invention, a system for estimating the health status of an individual is provided, comprising: an information acquisition unit for acquiring information on at least one of a mother and a baby; and a health status estimation unit for estimating the health status of at least one of the mother and the baby with reference to the information on the baby.

[0015] In addition, a non-transitory computer-readable recording medium recording another method for implementing the present invention, another system, and a computer program for executing the method are further provided.

[0016] According to the present invention, as a method for estimating the health status of an individual, information on at least one of a mother and a baby is obtained, and the health status of at least one of the mother and the baby can be estimated by referring to the information on the baby.

[0017] In addition, according to the present invention, by analyzing the lactation behavior pattern of an individual, it is possible to estimate the amount of milk produced by the mother, and to estimate the health status of the mother and / or offspring and the milk intake level of the offspring.

[0018] In addition, according to the present invention, it is possible to quickly and accurately determine the health status of an individual and, based on this, provide information necessary for raising the individual appropriately and in a timely manner, thereby supporting efficient management of the individual.

[0025] In this specification, an embodiment of a health status estimation system is described primarily focusing on the case of estimating the health status of cattle, but it should be understood that the health status estimation system of the present invention can also be applied to estimating the health status of other individuals such as horses and pigs.

[0026] Composition of the entire system

[0027] FIG. 1 is a diagram schematically illustrating the configuration of an entire system for estimating the health status of an object according to one embodiment of the present invention.

[0028] As illustrated in FIG. 1, the entire system according to one embodiment of the present invention may include a communication network (100), a health status estimation system (200), a sensor (300), and a device (400).

[0029] First, the communication network (100) according to one embodiment of the present invention can be configured regardless of the communication mode such as wired communication or wireless communication, and can be configured with various communication networks such as a local area network (LAN), a metropolitan area network (MAN), and a wide area network (WAN). Preferably, the communication network (100) referred to herein may be the well-known Internet or the World Wide Web (WWW). However, the communication network (100) is not necessarily limited thereto, and may include at least a portion of a well-known wired or wireless data communication network, a well-known telephone network, or a well-known wired or wireless television communication network.

[0030] For example, the communication network (100) may be a wireless data communication network that implements conventional communication methods such as WiFi communication, WiFi-Direct communication, Long Term Evolution (LTE) communication, 5G communication, Bluetooth communication (including Bluetooth Low Energy (BLE) communication), infrared communication, ultrasonic communication, etc., at least in part. As another example, the communication network (100) may be an optical communication network that implements conventional communication methods such as LiFi (Light Fidelity), etc., at least in part.

[0031] Meanwhile, the communication network (100) according to one embodiment of the present invention may be composed of two or more types of communication networks. For example, the communication network between the health status estimation system (200) and the device (400) may be a high-speed wireless communication network such as LTE communication or 5G communication, or a wired communication network, and the communication network between the health status estimation system (200) and the sensor (300) may be an LPWAN (Low Power Wide Area Network) such as LoRaWAN, SIGFOX, LTE-MTC, or Narrowband Internet of Things (NB-IoT).

[0032] However, the configuration of the communication network (100) according to one embodiment of the present invention is not limited to that described above, and may be variously changed within the scope that can achieve the purpose of the present invention.

[0033] Next, the health status estimation system (200) according to one embodiment of the present invention can perform a function of obtaining information about at least one of the mother and the offspring, and estimating the health status of at least one of the mother and the offspring based on the information about the maternal status.

[0034] The configuration and function of the health status estimation system (200) according to the present invention will be described in detail below.

[0035] Next, the sensor (300) according to one embodiment of the present invention is a digital device that includes a function to communicate after being connected to the health status estimation system (200), and may include a known 6-axis angular velocity / acceleration sensor. Accordingly, the acceleration and angular velocity (i.e., the rate of inclination in a certain direction) of the X-axis, Y-axis, and Z-axis can be measured by the sensor (300). Furthermore, the angular acceleration may be measured together with or instead of the angular velocity. Such a sensor (300) may be worn or inserted into a part of the body of an individual (e.g., a mother cow or calf) (e.g., the neck of the mother cow or calf). However, there is no particular limitation on the type of the sensor (300) according to one embodiment of the present invention and the position at which the sensor (300) is worn or inserted, and may be variously changed within the scope that can achieve the purpose of the present invention. For example, a sensor (300) according to one embodiment of the present invention may include a type of sensor other than an angular velocity and acceleration sensor, and may be inserted into the body of an object (e.g., a mother cow or calf).

[0036] In particular, the sensor (300) according to one embodiment of the present invention may include an application (not shown) that supports the user to receive services such as health status estimation from the health status estimation system (200). Such an application may be downloaded from the health status estimation system (200) or an external application distribution server (not shown). Meanwhile, the nature of such an application may be generally similar to the information acquisition unit (210), milk production estimation unit (220), health status estimation unit (230), communication unit (240), and control unit (250) of the health status estimation system (200) as described below. Here, at least a part of the application may be replaced with a hardware device or firmware device that can perform functions substantially the same as or equivalent to it, as necessary.

[0037] Next, a device (400) according to one embodiment of the present invention is a digital device that includes a function for communicating after connecting to a health status estimation system (200), and any digital device that has a memory means, a microprocessor, and a computing capability, such as a smart phone, a tablet, a smart watch, a smart band, smart glasses, a desktop computer, a notebook computer, a workstation, a PDA, a web pad, a mobile phone, etc., can be adopted as the device (400) according to the present invention.

[0038] In particular, the device (400) may include an application (not shown) that supports the user to receive services such as health status estimation from the health status estimation system (200). Such an application may be downloaded from the health status estimation system (200) or an external application distribution server (not shown). Meanwhile, the characteristics of such an application may be generally similar to the information acquisition unit (210), milk production estimation unit (220), health status estimation unit (230), communication unit (240), and control unit (250) of the health status estimation system (200), which will be described later. Here, at least a part of the application may be replaced with a hardware device or firmware device that can perform functions substantially identical to or equivalent thereto, as necessary.

[0039] Composition of a health status estimation system

[0040] Below, the internal configuration and functions of each component of the health status estimation system (200) that performs important functions for implementing the present invention will be examined.

[0041] FIG. 2 is a drawing showing in detail the internal configuration of a health status estimation system (200) according to one embodiment of the present invention.

[0042] As illustrated in FIG. 2, a health status estimation system (200) according to one embodiment of the present invention may be configured to include an information acquisition unit (210), a milk production estimation unit (220), a health status estimation unit (230), a communication unit (240), and a control unit (250). According to one embodiment of the present invention, at least some of the information acquisition unit (210), the milk production estimation unit (220), the health status estimation unit (230), the communication unit (240), and the control unit (250) may be program modules that communicate with an external system (not shown). These program modules may be included in the health status estimation system (200) in the form of an operating system, an application program module, or other program modules, and may be physically stored in various known memory devices. In addition, these program modules may also be stored in a remote memory device that can communicate with the health status estimation system (200). Meanwhile, these program modules include, but are not limited to, routines, subroutines, programs, objects, components, data structures, etc. that perform specific tasks or execute specific abstract data types, as described later in accordance with the present invention.

[0043] Meanwhile, although the health status estimation system (200) has been described as above, this description is exemplary, and it is obvious to those skilled in the art that at least some of the components or functions of the health status estimation system (200) may be realized within a device (300) or a server (not shown) or included within an external system (not shown) as needed.

[0044] First, the information acquisition unit (210) according to one embodiment of the present invention can perform a function of acquiring information about at least one of the mother and the offspring.

[0045] Specifically, the information acquisition unit (210) according to one embodiment of the present invention can acquire information on the breastfeeding-related behavior of an individual by estimating the behavior of the individual using sensor data measured by a sensor (300) for the individual. Here, according to one embodiment of the present invention, the obtainable breastfeeding-related behavior may include total breastfeeding time, number of breastfeeding stimuli, intensity (strength) of breastfeeding stimuli, breastfeeding frequency, breastfeeding duration, breastfeeding interval time, number of sucking behaviors, etc. According to one embodiment of the present invention, the health status of an individual can be predicted by utilizing such information on breastfeeding-related behavior. Fig. 3 is a diagram exemplarily showing a process of acquiring information on breastfeeding using sensor data according to one embodiment of the present invention.

[0046] As illustrated in FIG. 3, the information acquisition unit (210) according to one embodiment of the present invention can acquire information on the total breastfeeding time (311), the number of breastfeeding stimuli (312), the intensity of the breastfeeding stimuli (313), the breastfeeding frequency and duration (314), the breastfeeding interval time (315), and the number of sucking behaviors (316) using sensor data (310).

[0047] Next, the milk production estimation unit (220) according to one embodiment of the present invention can estimate the milk production of the mother by referring to information about lactation.

[0048] For example, the milk production estimation unit (220) according to one embodiment of the present invention can estimate that the calf wants to drink its mother's milk but the mother's milk production is insufficient when the milk stimulation ratio per milking time (number of milking stimulations / milk time) of a calf that maintains an average (typical) milking duration per time exceeds a predetermined standard (e.g., 25 times / minute or more) and is maintained for a certain period of time or longer.

[0049] In addition, the milk production estimation unit (220) according to one embodiment of the present invention can estimate the vitality of the offspring and / or the milk production status of the mother based on information about the intensity (strength) of the maternal stimulation.

[0050] For example, the milk production estimation unit (220) according to one embodiment of the present invention can estimate that the calf's vitality is good and / or the mother's milk production is insufficient when the average (typical) milk production intensity per feeding of the calf exceeds a predetermined standard and is maintained for a certain period of time.

[0051] Next, the health status estimation unit (230) according to one embodiment of the present invention can perform a function of estimating the health status of the mother and the offspring by referring to information on the mother's milk production and the offspring's lactation.

[0052] For example, the health status estimation unit (230) according to one embodiment of the present invention can estimate that the calf lacks the will and vitality to nurse if the calf cannot maintain the average (typical) nursing duration per session and the nursing stimulation ratio per nursing time (number of nursing stimulations / nursing time) falls below a predetermined standard (e.g., 15 times / minute or less) and is maintained for a certain period of time or longer.

[0053] In addition, the health status estimation unit (230) according to one embodiment of the present invention can estimate the vitality status of the offspring based on information about the intensity (strength) of the maternal stimulus.

[0054] For example, the health status estimation unit (230) according to one embodiment of the present invention can estimate that the vitality status of the calf is poor when the average (typical) breastfeeding intensity per feeding of the calf remains below a predetermined standard for a certain period of time.

[0055] In addition, the health status estimation unit (230) according to one embodiment of the present invention can determine the will and vitality of the offspring to breastfeed based on information about the breastfeeding frequency and the duration of breastfeeding, and can determine the basic health status of the individual based on this.

[0056] For example, the health status estimation unit (230) according to one embodiment of the present invention can estimate that the calf has a strong will to breastfeed and / or has strong vitality in response to the fact that the breastfeeding frequency and breastfeeding duration of the calf exceed a predetermined standard value.

[0057] For another example, the health status estimation unit (230) according to one embodiment of the present invention may estimate that the calf's will to breastfeed and / or vitality is weak when the breastfeeding frequency and breastfeeding duration of the calf fall below a predetermined standard.

[0058] In addition, the health status estimation unit (230) according to one embodiment of the present invention can infer the sucking speed by determining the number of times the mother sucks her milk and estimate the will and vitality of the offspring to suckle.

[0059] For example, the health status estimation unit (230) according to one embodiment of the present invention can estimate that the calf's will to breastfeed and / or vitality is strong when the number of times the calf breastfeeds exceeds a predetermined standard and is maintained for a certain period of time.

[0060] For another example, the health status estimation unit (230) according to one embodiment of the present invention may estimate that the calf's will to nurse and / or vitality is weak when the number of times the calf is nursed is maintained at a level below a predetermined standard for a certain period of time.

[0061] According to the above-described embodiments, a system for determining the milk intake level of a calf can be implemented, and further, by synthesizing other behavioral data of the individual (rumination, feed intake, activity level, sitting / standing, etc.), a system for more precisely determining the health status of the individual can be implemented.

[0062] Meanwhile, Fig. 4 is a diagram exemplarily showing a process for estimating the health status of an individual according to one embodiment of the present invention. Specifically, referring to Fig. 4, the overall operation process of the health status estimation system (200) will be described. Sensor data (310) according to one embodiment of the present invention may be acquired through a sensor (300) for an individual and then wirelessly transmitted to a cloud server through a Farmer's Hands gateway (320). Here, the gateway through which the sensor data (310) according to one embodiment of the present invention is transmitted may be a Farmer's Hands gateway, but is not necessarily limited thereto, and it should be noted that changes may be made in any way within a scope that can achieve the purpose of the present invention.

[0063] Continuing with reference to FIG. 4, sensor data (310) for an object according to one embodiment of the present invention may be transmitted to a cloud server (201) that collects raw signals through a gateway (320) via the Internet and / or a wired connection, and then transmitted to an AI analysis server (202) via the Internet and / or a wired connection, where the object's behavior may be analyzed by AI, and then transmitted to a behavior data cloud server (203) via the Internet and / or a wired connection and stored. Thereafter, in response to a user requesting data inquiry through a device (400), the sensor data (310) may be transmitted to the device (400) via the Internet and / or wirelessly. However, it should be noted that elements such as a server that transmits, analyzes, and stores sensor data (310) included in the health status estimation system according to the present invention are not necessarily limited to the elements described above, and may be changed in any way within a scope that can achieve the purpose of the present invention.

[0064] Meanwhile, the health status estimation unit (230) according to one embodiment of the present invention can classify the mother as a breeding cow and continuously manage the mother as a breeding cow in response to the fact that the average milk production by parity of the mother satisfies the will of the calf to be fed by referring to the suckling behavior of the calf and that the calf remains in good health for a certain period of time or longer.

[0065] In addition, the health status estimation unit (230) according to one embodiment of the present invention can classify the mother as an individual to be culled from the breeding herd in response to the fact that the average milk production of the mother per parity does not satisfy the will of the offspring to suckle and the average health of the offspring is not good for a certain period of time or longer by referring to the suckling behavior of the offspring.

[0066] Here, the parity according to one embodiment of the present invention can be expressed as N parity when a mother cow has given birth to N calves, and by classifying breeding cows and / or individuals to be culled with reference to the average milk production amount by parity of the mother cow, it is possible to accurately identify health problems due to lactation among various factors affecting the health of calves, thereby preventing errors.

[0067] Specifically, the health status estimation unit (230) according to one embodiment of the present invention can classify a mother as a breeding cow and / or an individual to be culled while preventing an error of misjudging the mother as a breeding cow (for example, an error of classifying a mother as an individual to be culled because the offspring is born in a congenitally unhealthy state even though the mother's lactation status is not a problem) by taking into account the average parity of the mother and the average health status of the offspring as a whole.

[0068] Next, the communication unit (240) according to one embodiment of the present invention can perform a function that enables data transmission and reception from / to the information acquisition unit (210), the milk production amount estimation unit (220), and the health status estimation unit (230).

[0069] Finally, the control unit (250) according to one embodiment of the present invention can perform a function of controlling the flow of data between the information acquisition unit (210), the milk production estimation unit (220), the health status estimation unit (230), and the communication unit (240). That is, the control unit (250) according to one embodiment of the present invention can control the flow of data from / to the outside of the health status estimation system (200) or the flow of data between each component of the health status estimation system (200), thereby controlling the information acquisition unit (210), the milk production estimation unit (220), the health status estimation unit (230), and the communication unit (240) to perform their own functions.

[0070] The embodiments of the present invention described above may be implemented in the form of program commands that can be executed through various computer components and recorded on a computer-readable recording medium. The computer-readable recording medium may include program commands, data files, data structures, etc., either singly or in combination. The program commands recorded on the computer-readable recording medium may be specially designed and configured for the present invention or may be known and available to those skilled in the art of computer software. Examples of computer-readable recording media include magnetic media such as hard disks, floppy disks, and magnetic tapes, optical recording media such as CD-ROMs and DVDs, magneto-optical media such as floptical disks, and hardware devices specifically configured to store and execute program commands, such as ROMs, RAMs, and flash memories. Examples of program commands include not only machine language codes generated by a compiler, but also high-level language codes that can be executed by a computer using an interpreter, etc. Hardware devices may be changed into one or more software modules to perform processing according to the present invention, and vice versa.
