Description

  The present invention relates to a cow body temperature output device that sequentially outputs the body temperature of a cow, and more particularly to a cow body temperature output device that corrects the epidermis temperature and outputs the body temperature.

  Cattle health management is the most important matter for cattle farmers, whether breeding or fattening. Conventionally, health care has been taken by paying attention to the appearance, movement, and behavior of the cow, such as the color, appetite, and eyes.

  Here, for farmers who adopt large-scale management or grazing breeding that is being reviewed in recent years, there are cases where it is not always enough to see, and in the case of small-scale management, even one of them will die If something like this happens, you will be hit hard.

  Therefore, body temperature measurement, which is the basis for grasping a health condition body, has also been conventionally performed. According to this, in addition to general health management, for example, when a childbirth is about to occur, the phenomenon that the body temperature decreases by 0.3 to 0.5 degrees from the normal time can be used for detection of childbirth.

  However, rectal examinations are not always measured at all, and are performed as part of the diagnosis, such as when the patient feels unwell.

  That is, the problem to be solved is that the cow's body temperature is constantly measured without placing a burden on the cow.

  The cow body temperature output device according to claim 1 includes a temperature sensor that is brought into contact with the skin of the cow, a heat insulating covering that sandwiches the temperature sensor and covers the temperature sensor from above so as to be applied to the skin from the opposite side of the skin, And a conversion output unit that corrects and outputs the epidermis temperature from the temperature sensor as a body temperature based on the rectal temperature.

  That is, the invention according to claim 1 does not affect the sensor even if the cow is outdoors or lying down, and can always measure body temperature by performing a predetermined correction.

  The cow body temperature output device according to claim 2 is the cow body temperature output device according to claim 1, wherein the cow body temperature or the change width of the cow body temperature deviates from a predetermined value based on the outside air temperature and / or the change width of the outside air temperature. It is characterized by having a determination unit for determining whether or not.

  That is, the invention according to claim 2 can quickly grasp the physical condition change of the cow.

  According to the present invention, it is possible to always measure the cow body temperature without placing a burden on the cow.

It is the mounting | wearing conceptual diagram which attached the cow body temperature output apparatus to the cow. It is an external appearance block diagram of a cow body temperature output device. It is a block diagram of a cow body temperature output device. It is the figure which showed the other structural example and mounting | wearing aspect of the cow body temperature output apparatus.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a conceptual diagram of mounting the cow body temperature output device attached to a cow. FIG. 2 is an external configuration diagram of the cow body temperature output device.
FIG. 3 is a block diagram of the cow body temperature output device. The cow body temperature output device 100 includes a temperature sensor unit 101, a sensor sheet body 102, a fixing belt 103, and a processing output unit 104.

  The temperature sensor unit 101 is a sensor that is brought into contact with a cow skin and measures the skin temperature. The sensor may be a mercury thermometer, a thermometer using a thermocouple, or a thermometer using infrared rays. A value measured by the temperature sensor unit 101 is converted into a body temperature by the processing output unit 104.

  The sensor sheet body 102 is a flat pad that covers the temperature sensor unit 101 from above (from the outside) on the opposite side of the epidermis with the temperature sensor unit 101 interposed therebetween (from the outside) so as to be applied to the cattle epidermis. The material should be flexible so that no stress is applied to the cow, and a highly heat-insulating material will be used. Thereby, even if there are fluctuations in the outside air temperature, the temperature sensor unit 101 is hardly affected, and the correction accuracy to the body temperature is improved. Although the size is not limited, it can be 5 cm × 7 cm × 1 cm. The periphery of the temperature sensor unit 101 may be raised to 2.5 cm so that the influence of the outside air temperature is reduced.

  The fixing belt 103 is a belt that fixes the sensor sheet body 102 to the cow. As shown in the figure, the fixing belt 103 is a belt that winds the back of the torso and the back of the front leg (armpit under the human side), and fixes the sensor sheet body 102 to be positioned under the armpit. This is a place where cows are not likely to hit the soil even when they sit down, and are not easily wet by rain. The sensor sheet body 102 is not limited to this, and may be attached to the vicinity of the torso.

  The process output unit 104 includes a conversion unit 141, an output unit 142, a determination unit 143, and a notification unit 144.

  The conversion unit 141 corrects the skin temperature of the cow measured by the temperature sensor unit 101 based on the rectal temperature and outputs it as the body temperature of the cow. Since the body temperature of the cow is effectively the rectal temperature, the epidermis temperature is corrected by this rectal temperature. The difference between the rectal temperature and the epidermis temperature (for example, 0.9 ° C.) is measured in advance, and the body temperature is determined based on the epidermis temperature. When this difference depends on time, it is corrected as needed. Rectal temperature cannot be measured at all times, but epidermis temperature can be measured at any time, and this can be used to grasp changes in body temperature over time.

  The output unit 142 is designed as a terminal here, and can appropriately transmit data on body temperature change accumulated every predetermined time to the outside. In other words, the output unit 142 is an interface, and can be a USB terminal, a smart media connection connector, or the like.

  The determination unit 143 determines whether the cow body temperature or the change width of the cow body temperature deviates from a predetermined value based on the outside air temperature and / or the change width of the outside air temperature. This makes it possible to more accurately determine whether or not a physical condition change has occurred in consideration of changes in the outside air temperature. Depending on the mode of use, it can also be used to detect estrus, parturition, and the like.

  Here, the notification unit 144 provides an LED to the sensor sheet body 102 to notify the outside. Based on the result of the determination unit 143, the notification content is configured to blink once every 2 seconds if there is a possibility of a change in physical condition, and once every 10 seconds if within the normal range. . In addition, when such a flashing method is adopted, the battery life is improved. Depending on the mode of use, it may be linked to the output unit 142 and sent to a barn or a management shed by radio waves, and displayed in real time on a built-in PC.

  As described above, according to the present invention, it is possible to constantly measure and confirm the cow body temperature without imposing a burden on the cow. As shown in FIG. 4, the sensor sheet body 102 and the processing output unit 104 may be configured as separate bodies, and both may be connected by a connection cable along the fixed belt 103. By attaching the processing output unit 104 to the rear of the torso and wirelessly communicating with the barn, the convenience of livestock farmers having a large management scale can be enhanced.

  The present invention can be applied not only to cattle but also to pigs and horses.
