Detailed ways

The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, only used to explain the present invention, and should not be construed as a limitation of the present invention.

This application is based on the inventor's findings and knowledge of the following facts and problems:

In animal husbandry, long-term and continuous temperature monitoring of livestock is extremely important. Since most economic livestock are warm-blooded animals, their body temperature is directly related to physiological and pathological phenomena. Therefore, monitoring the body temperature of livestock is an important way to timely or early detect livestock plague, illness, estrus, and calving. For example, the body temperature of female livestock will increase by about 1°C when they are in estrus. Accurate monitoring of the body temperature of female livestock is extremely important to improve the accuracy of fertilization. Another example is a 2°C drop in a cow's body temperature, which may signal a life-threatening visceral rupture, a serious illness such as a toxic disease. Due to the high price and high feeding cost of large economical livestock (such as sows, dairy cows, cows, etc.), the physiological and pathological phenomena of livestock can be detected early, and rapid isolation, timely treatment, accurate fertilization, safe birth, etc. It is of great significance to reduce breeding costs, avoid economic losses, and improve output efficiency in animal husbandry.

In the current breeding industry, the body temperature measurement of livestock generally includes two methods. One way of measurement is to use a measuring device such as a thermometer to measure the body temperature, for example, a thermometer is inserted through the anus of the animal to measure the body temperature of the animal. The disadvantage of this method is that it cannot be measured continuously, and the livestock to be tested must be captured for each measurement, which is time-consuming and labor-intensive, and it is difficult to achieve universal measurement in large-scale livestock breeding. Another way is to use in vitro non-contact measurement, for example, using a measuring device such as an ear thermometer (ie, an infrared thermometer) to irradiate a specific location on the surface of the livestock. The disadvantage of this method is that because the body surface temperature of livestock is affected by various factors, it is sometimes difficult to reflect the real body temperature of the livestock, and each measurement needs to point to a fixed position on the body surface of the livestock, which is time-consuming to operate.

In addition, the data obtained by these common measurement methods also need to be recorded manually, and then input into systems such as computers for storage and data analysis; and for livestock in groups, due to the continuous movement of livestock, it is necessary to distinguish each livestock to complete the measurement. Data logging makes the temperature acquisition process inefficient.

To this end, some methods of measuring the body temperature of livestock using micro-sensor technology and wireless communication technology have emerged. For example, a temperature sensor is implanted in the body of the animal to be tested, and then wireless communication is used to enable the temperature sensor implanted in the body to transmit the temperature signal by means of wireless signal transmission. However, this type of measurement requires the implantation of batteries in livestock, which tend to be bulkier for long-term temperature monitoring, resulting in higher implantation costs and higher risk of infection in livestock. In addition, for the power supply method using wireless energy supply, due to the limitation of wireless energy transmission distance, the external data reading system needs to be close to the position where the sensor is implanted in the livestock under test. Therefore, the operation is inconvenient and the temperature collection efficiency is not high.

In order to solve the above technical problems, the present invention proposes a temperature measuring device 10 for the auricle. The temperature measuring device 10 for the auricle is suitable for being installed on the auricle of an animal, and can realize accurate and automatic temperature measurement of the animal's body temperature. , Continuous and universal measurement, it has the advantages of convenient operation, high measurement efficiency, low installation cost, and the livestock is not easy to be infected.

After the installation is completed, the inlay 01 penetrates the auricle 20 and is located in the perforation. As the wound at the perforation heals, the perforation gradually shrinks. The embedded body 01 is further transmitted to the temperature sensor 02 in the accommodating cavity through the thermally conductive material 05. The temperature sensor 02 transmits the temperature signal of the auricle 20 to the signal wireless transmission circuit 07, and finally the signal wireless transmission circuit 07 transmits the temperature signal wirelessly. To the external wireless receiving system, in this way, the body temperature signal of livestock can be collected, transmitted and processed.
