Description

Technical Field

[0001] This invention relates to large-scale automated livestock farming technology, and in particular to a livestock farrowing indicator light and method based on temperature detection. Background Technology

[0002] Over the past few decades, with my country's continuous population growth, rising economic level, and rapid urban expansion, the proportion and total amount of animal protein consumed in the diet have been increasing, driving rapid growth in the scale of livestock farming. Furthermore, continuous development of breeding technology, various agricultural and livestock subsidies, and relaxed environmental policies have promoted the transformation of livestock farming from traditional to intensive methods. To reduce breeding costs, large-scale automated livestock farms employ fewer staff and utilize automated feeding and cleaning technologies, ensuring economic efficiency. However, livestock farrowing periods are relatively concentrated and the process is lengthy. During farrowing, staff are extremely busy monitoring the condition of many animals, and accidents such as livestock deaths due to lack of care often occur, especially in very large-scale farms where the large number of animals makes timely detection of farrowing even more difficult. Summary of the Invention

[0003] To address the issues in existing technologies where livestock farrowing occurs in a concentrated period and involves a lengthy process, resulting in extremely busy work schedules for personnel monitoring numerous animals during farrowing, and frequent accidents such as livestock deaths due to lack of care, this invention proposes a temperature-detection-based livestock farrowing indicator light and method. This system can automatically detect the farrowing status of livestock and is particularly adaptable to different ambient temperatures, ensuring the wide applicability of the temperature-detection-based livestock farrowing indicator light.

[0004] To achieve this goal, the present invention adopts the following technical solution.

[0005] A temperature-detection-based livestock farrowing indicator light includes a light-emitting unit, a battery, and a control unit. The control unit is connected to the battery and the light-emitting unit, and the battery provides power to the light-emitting unit and the control unit. The overall structure of the temperature-detection-based livestock farrowing indicator light is capsule-shaped, with the light-emitting unit at one end and a cylindrical capsule body at the other. The surface of the cylindrical capsule body has a second temperature sensor, which is connected to the control unit and the battery, among other necessary structures. Based on the detection result of the second temperature sensor, the control unit determines that the temperature-detection-based livestock farrowing indicator light has been expelled from the livestock's body and controls the light-emitting unit to emit a warning light.

[0006] The basic concept of this patent lies in placing a capsule-shaped, temperature-detecting livestock farrowing indicator light into the animal's birth canal. This capsule-shaped structure facilitates smooth expulsion during farrowing. The temperature-detecting indicator light enables automatic detection of farrowing. For example, during automatic detection, the indicator light is first expelled by the animal. Due to the temperature difference between the animal's body and the environment, a second temperature sensor detects this, and the control unit then activates the light-emitting part to emit an alarm light. Therefore, this invention offers the technical advantages of accurate and reliable detection.

[0007] In addition, in the livestock farrowing indicator light based on temperature detection of the present invention, the front end of the light-emitting part has a flexible extended light-emitting end, which is a hollow flexible tube. The flexible extended light-emitting end is disposed outside the livestock body and has a first temperature sensor on it for detecting the external ambient temperature. The first temperature sensor is connected to the control unit and the battery. When the difference between the temperature detected by the second temperature sensor and the external ambient temperature detected by the first temperature sensor is less than a predetermined threshold, the control unit determines that the livestock farrowing indicator light based on temperature detection is discharged from the livestock body and controls the light-emitting part to emit a warning light.

[0008] In a more specific embodiment of the present invention, to more accurately detect farrowing, it is necessary to determine the external ambient temperature and use it as a benchmark to compare the temperature detection results of the second temperature sensor. Otherwise, the control unit needs to detect "abrupt changes" in the temperature detection results of the second temperature sensor, which requires the control unit to record the temperature calculation results of the second temperature sensor for at least a period of time, which is relatively complex. To eliminate the need for a storage unit, the external ambient temperature, for example 25 degrees Celsius, can be detected using a first temperature sensor initially placed outside the livestock's body, while the internal temperature of the livestock is, for example, 38-39 degrees Celsius. When the temperature detected by the second temperature sensor is within 2 degrees Celsius (plus or minus 2 degrees), the control unit determines that the temperature-based farrowing indicator light has been emitted from the livestock's body and controls the light-emitting part to emit a warning light. In this embodiment, the temperature-based farrowing indicator light does not require additional data storage; only the detection results of the first and second temperature sensors need to be sent to a comparator, and the comparator's result is sufficient. Therefore, it has the advantages of simple structure, ease of implementation, and high stability.

[0009] In addition, in the livestock farrowing indicator light based on temperature detection of the present invention, the foremost end of the flexible extended light-emitting end has a ring handle; the first temperature sensor is disposed inside the ring handle, at the rear end of the ring handle.

[0010] As shown in the previous embodiment, obtaining accurate external ambient temperature is one of the basic conditions of the technical solution of this invention. To prevent the first temperature sensor outside the livestock from drooping due to the flexible extended light-emitting end or from adhering to the livestock's body due to squatting or lying down, thus causing the "external ambient temperature" detected by the first temperature sensor to actually be the livestock's body surface temperature, this embodiment of the invention provides a ring-shaped handle at the very front end of the flexible extended light-emitting end. This ring-shaped handle allows the operator to lift the temperature-detection-based livestock farrowing indicator light, or serves to suspend it. Specifically, the first temperature sensor is positioned inside the ring-shaped handle, ensuring that it does not directly contact the livestock's body surface regardless of whether the flexible extended light-emitting end droops or the livestock is squatting or lying down. Furthermore, the first temperature sensor is located at the rear end of the ring-shaped handle, near the connection point between the flexible extended light-emitting end and the ring-shaped handle. This position prevents the operator from holding the temperature-detection-based livestock farrowing indicator light, ensuring that the detection result of the first temperature sensor is not interfered with by the operator and protecting the first temperature sensor.

[0011] Furthermore, in the livestock farrowing indicator light based on temperature detection of the present invention, the front end of the capsule-shaped structure of the livestock farrowing indicator light is a hemispherical light-emitting part, which is covered by a flexible transparent shell and contains multiple light-emitting elements; multiple second temperature sensors are located at different sections of the front and rear of the cylindrical capsule body surface, and the multiple second temperature sensors detect the temperature respectively; the control unit determines the process of the livestock farrowing indicator light being expelled from the livestock body at different times based on the difference between the temperature detected by the second temperature sensor at different sections and the external ambient temperature detected by the first temperature sensor being less than a predetermined threshold, and controls some or all of the multiple light-emitting elements to emit warning light based on the process of the livestock farrowing indicator light being expelled from the livestock body.

[0012] To further improve the detection accuracy and flexibility of the present invention, and to provide a more flexible warning mechanism, in a specific embodiment of the present invention, multiple second temperature sensors are located at different sections on the front and rear of the cylindrical capsule body. These second temperature sensors can detect temperature information separately. Because the livestock farrowing indicator light based on temperature detection is gradually expelled from the livestock, the outermost (front end) second temperature sensor can first detect the temperature near the external ambient temperature. As the expulsion process progresses, the other second temperature sensors can also gradually detect the temperature near the external ambient temperature. For example, t1, t2, ..., tn are the time points when the temperature detected by each second temperature sensor differs from the external ambient temperature by less than a predetermined difference. In this way, the control unit can determine the dynamic process of the livestock farrowing indicator light being expelled from the livestock. In the initial stage of the livestock farrowing indicator light being expelled from the livestock, the control unit controls a small number of light emitters to emit light, while in the later stage of the livestock farrowing indicator light being expelled from the livestock, the control unit controls a large number or even all of the light emitters to emit light. The purpose of this setup is to avoid emitting strong light that could cause an overreaction in livestock or other animals during the initial stage when the temperature-detection livestock farrowing indicator light is expelled from the animal's body, while emitting stronger light later to provide a more obvious indication.

[0013] In addition, the livestock farrowing indicator light based on temperature detection of the present invention also includes a third temperature sensor, which is connected to the control unit and the battery. When the difference between the external ambient temperature detected by the first temperature sensor and the internal temperature of the livestock is less than a predetermined threshold, the control unit activates the third temperature sensor. The third temperature sensor is disposed on the outer surface of the cylindrical capsule body and includes a strip structure bent into the outer contour of the cross-section of the cylindrical capsule body. The strip structure is filled with a porous filler, which encapsulates a heating element and multiple third temperature detection units. The first third temperature detection unit is in close contact with the heating element, and the other third temperature detection units are spaced apart from the first third temperature detection unit along the length of the strip structure. The heating element and the multiple third temperature detection units are all connected to the control unit and the battery. This is used to detect animals according to a detection cycle. During the detection sub-cycle, the control unit controls the heating element to generate heat. The first third temperature detection unit detects the temperature of the heating element. When the temperature reaches the first predetermined temperature, the heating unit stops heating. When the temperature is lower than the first predetermined temperature by more than a predetermined difference, the heating unit continues heating. During the detection sub-cycle, when other third temperature detection units detect that the temperature has reached the second predetermined temperature, the control unit records the time difference between ...

[0014] In specific embodiments of the present invention, it is necessary to ensure that the livestock farrowing indicator light based on temperature detection has a wider range of applicability. For example, when livestock are farrowing in summer, the external environment may also reach near the livestock's body temperature, such as 36-40 degrees Celsius. At this time, whether the "sudden change" in temperature is directly detected by the second temperature sensor or the difference between the detection results of the first and second temperature sensors is used, it is impossible to obtain accurate results. The temperature detection is no longer sensitive. Therefore, the livestock farrowing indicator light based on temperature detection is difficult to play the role of emitting warning light based on the state of the livestock being expelled from the body.

[0015] To address this issue, in this specific embodiment of the invention, a third temperature sensor is used as a supplement for this special case. When the difference between the external ambient temperature detected by the first temperature sensor and the livestock's body temperature is significant, it is not necessarily necessary to utilize the results of the third temperature sensor. Alternatively, the third temperature sensor can be used as an auxiliary means. When the difference between the external ambient temperature detected by the first temperature sensor and the livestock's body temperature is small, the control unit activates the third temperature sensor, and determines, based on the detection results of the third temperature sensor, that the temperature-based livestock farrowing indicator light should be released from the livestock's body.

[0016] The working principle of the third temperature sensor is as follows: The third temperature sensor is located on the outer surface of the cylindrical capsule body and includes a strip-shaped structure bent to form the outer contour of the cylindrical capsule body's cross-section. This strip-shaped structure is filled with a porous filler, which encloses a heating element and multiple third temperature detection units. The porous filler, such as sponge or foam, has water-absorbing properties. When the temperature-detecting livestock farrowing indicator light is located inside the livestock, it can absorb surrounding moisture. At this time, the thermal conductivity of the porous filler is close to that of water, providing good thermal conductivity and convection. The third temperature sensor has a detection cycle, which is divided into a detection sub-cycle and a cooling sub-cycle. In the detection sub-cycle, the control unit first controls the heating element to generate heat. The first third temperature detection unit is in close contact with the heating element and detects its temperature. When a first predetermined temperature is reached, the heating unit stops heating; when the temperature drops below the first predetermined temperature by more than a predetermined difference, the heating unit continues heating. In this way, during the entire detection sub-cycle, the first third temperature detection unit basically fluctuates around a constant temperature. This constant temperature can be set as needed. For example, if the external ambient temperature is 36 degrees Celsius, then this constant temperature can be set to 43 degrees Celsius. As mentioned earlier, when the temperature-detecting livestock farrowing indicator light is located inside the birth canal, the heat can be easily transferred along the strip structure of the third temperature sensor because the pores of the porous filler are filled with moisture. The temperature detected by the second third temperature detection unit can also rise quickly, for example, to 41 degrees Celsius; subsequently, the temperature detected by the third third temperature detection unit can also rise quickly, for example, to 41 degrees Celsius as well. The control unit records the time difference between each subsequent third temperature detection unit detecting a temperature of 41 degrees Celsius and the previous third temperature detection unit detecting a temperature of 41 degrees Celsius. For example, the time difference between the second and first third temperature detection units detecting a temperature of 41 degrees Celsius is dt1, and the time difference between the second and second third temperature detection units detecting a temperature of 41 degrees Celsius is dt2. Based on the values ​​of dt1 and dt2, the control unit can determine the overall thermal conductivity of the strip structure of the third temperature sensor, thereby inferring whether the third temperature sensor (the temperature-detecting livestock farrowing indicator light) is located inside or outside the livestock.

[0017] If dt1 and / or dt2 are small, for example, less than 30 seconds, the control unit determines that the third temperature sensor is still inside the livestock. After the detection sub-cycle ends, a cooling sub-cycle begins to cool the heating element, so that detection can restart when the next detection cycle arrives. The cooling sub-cycle can be set to a length significantly longer than the detection sub-cycle.

[0018] It should be noted that, in order to prevent the heat emitted by the heating element from being directly transferred into the birth canal, which would prevent the second and third temperature detection units from detecting temperatures such as 41 degrees Celsius, an insulating film can be covered on the outer part of the third temperature sensor, especially on the outer areas corresponding to the heating element and each temperature detection unit. In this way, the heat detected by each temperature detection unit comes more from the transmission along the length of the strip structure.

[0019] When the temperature-detecting livestock farrowing indicator light is expelled from the animal's body, the moisture in the porous filler is rapidly expelled due to the squeezing action of the birth canal, the drying effect of the external environment, and the evaporation effect of the heating element. At this point, the porous filler can no longer maintain good heat conduction and convection capabilities. Assuming that within a detection sub-cycle, the time difference between the second and third temperature detection units reaching 41 degrees Celsius and the first unit reaching 41 degrees Celsius is dt1, and the time difference between the third and second units reaching 41 degrees Celsius is dt2, then dt1 and dt2 will be even longer, exceeding the predetermined length and even the length of the detection sub-cycle. In other words, within this detection sub-cycle, the second or third temperature detection unit cannot detect a temperature of 41 degrees Celsius. The control unit determines that the third temperature sensor has been expelled from the animal's body and begins to control the light-emitting part to emit light.

[0020] Therefore, the specific embodiments of the present invention ingeniously utilize the moisture content of the porous filler to determine whether the temperature-detection-based livestock farrowing indicator light has been expelled from the livestock's body. Thus, the present invention can overcome the problem that the temperature-detection-based livestock farrowing indicator light is difficult to work due to the proximity of the external ambient temperature and the livestock's body temperature, making the temperature-detection-based livestock farrowing indicator light of the present invention more widely applicable.

[0021] Furthermore, in the livestock farrowing indicator light based on temperature detection of the present invention, multiple third temperature sensors are arranged at equal intervals along the circumference on the same section of the outer surface of the cylindrical capsule body. Each temperature sensor includes a heating element and multiple third temperature detection units. The outer surface of the cylindrical capsule body has multiple curved grooves corresponding to the sections of the third temperature sensors. Each curved groove contains one third temperature sensor. The bottom and sides of the curved grooves are made of heat-insulating material. The outer surface of the strip structure of the third temperature sensor is flush with the outer surface of the cylindrical capsule body. The multiple third temperature detection units are all connected to the control unit and the battery. The control unit determines that the livestock farrowing indicator light based on temperature detection is discharged from the livestock body based on the time difference between when the temperature detected by each of the other third temperature detection units reaches the second predetermined temperature and when the temperature detected by the previous third temperature detection unit reaches the second predetermined temperature, and controls the light-emitting part to emit warning light.

[0022] There is a special case to consider: after the temperature-detecting livestock farrowing indicator light is expelled, it falls to the ground, where there is moisture. This moisture can be absorbed into the strip-shaped structure of the third temperature sensor. This special case renders the aforementioned method of using the moisture content of the porous filler to determine whether the temperature-detecting livestock farrowing indicator light has been expelled from the livestock ineffective. Therefore, in this specific embodiment of the invention, multiple third temperature sensors are arranged at equal intervals along the circumference on the same section of the outer surface of the cylindrical capsule body. For example, four third temperature sensors are arranged at 90-degree intervals. According to the above operation, whichever third temperature sensor detects a longer dt1 or dt2 can be used as the basis for determining that the temperature-detecting livestock farrowing indicator light has been expelled from the livestock.

[0023] Specifically, the outer surface of the cylindrical capsule body has multiple curved grooves corresponding to the section of the third temperature sensor. Each curved groove contains a third temperature sensor. The bottom and sides of the curved grooves are made of heat-insulating material, which ensures that heat is transferred along the length of the strip structure of the third temperature sensor and does not enter the cylindrical capsule body.

[0024] Furthermore, in the livestock farrowing indicator light based on temperature detection of the present invention, in each of the multiple sections on the outer surface of the cylindrical capsule body, a plurality of third temperature sensors are arranged at equal intervals along the circumference. Each temperature sensor includes a heating element and a plurality of third temperature detection units. The plurality of third temperature detection units are all connected to the control unit and the battery. The control unit determines the process of the livestock farrowing indicator light being expelled from the livestock body based on the detection results of the plurality of third temperature detection units in each of the multiple sections, and controls the luminous brightness of the light-emitting part based on the process of the livestock farrowing indicator light being expelled from the livestock body.

[0025] A third temperature sensor is used to determine the status of the temperature-detection-based livestock farrowing indicator light. Multiple sections can be set, with four third temperature sensors in each section. Following a similar principle to the previous implementation, the control unit can determine the dynamic process of the temperature-detection-based livestock farrowing indicator light being expelled from the livestock. In the initial stage of expulsion, the control unit controls a small number of light-emitting elements to emit light, while in the later stage, the control unit controls a large number, or even more, light-emitting elements to emit light.

[0026] This invention also includes a method for indicating livestock parturition based on temperature detection, the method comprising the following steps:

[0027] A. Detect the external temperature using a first temperature sensor installed on the outside of the livestock;

[0028] B. Temperature is detected using a second temperature sensor on the cylindrical capsule body of the livestock farrowing indicator light based on temperature detection;

[0029] C. When the difference between the temperature detected by the second temperature sensor and the external ambient temperature detected by the first temperature sensor is less than a predetermined threshold, it is determined that the livestock farrowing indicator light based on temperature detection has been expelled from the livestock's body, and the light-emitting part is controlled to emit a warning light.

[0030] Furthermore, in the livestock farrowing alert method based on temperature detection of the present invention, multiple second temperature sensors are provided at different positions on the front and back of the surface of the cylindrical capsule body, and the multiple second temperature sensors detect the temperature respectively; the control unit determines the process of the livestock farrowing alert light being expelled from the livestock body at different times based on the temperature difference between the second temperature sensor at different positions and the external ambient temperature detected by the first temperature sensor being less than a predetermined threshold, and controls the luminous intensity of the light-emitting part based on the process of the livestock farrowing alert light being expelled from the livestock body.

[0031] Furthermore, in the livestock parturition alerting method based on temperature detection of the present invention, when the difference between the external ambient temperature detected by the first temperature sensor and the internal temperature of the livestock is less than a predetermined threshold, the following operations are performed:

[0032] B01. The control unit activates the third temperature sensor;

[0033] B02. Within a detection cycle, in a detection sub-cycle, the control unit controls the heating element of the third temperature sensor to generate heat. The first third temperature detection unit detects the temperature of the heating element. When the first predetermined temperature is reached, the heating unit stops heating. When the temperature is lower than the first predetermined temperature by more than the difference, the heating unit continues to heat.

[0034] B03. In this detection sub-cycle, when the temperature detected by other third temperature detection units of the third temperature sensor reaches the second predetermined temperature, the control unit records the time difference between the temperature detected by the third temperature detection unit reaching the second predetermined temperature and the temperature detected by the previous third temperature detection unit reaching the second predetermined temperature, in order to determine whether the livestock farrowing indicator light based on temperature detection has been expelled from the livestock. If the result is no, the control unit waits for the cooling sub-cycle before proceeding to the next detection cycle and repeats steps B02 and B03.

[0035] B04. If the result is confirmed to be yes, then control the light-emitting part to emit a warning light.

[0036] In summary, the technical effects of this invention include the following.

[0037] (1) In the livestock farrowing indicator light based on temperature detection of the present invention, the temperature detection result is innovatively used as the basis for judging whether the livestock farrowing indicator light based on temperature detection has been expelled from the livestock body. Therefore, the livestock farrowing indicator light based on temperature detection does not need a moving unit and does not need to be deformed. The detection is convenient and flexible. Because temperature sensors are widely used, they have the advantages of simple selection and high sensitivity.

[0038] (2) In the livestock farrowing indicator light based on temperature detection of the present invention, by setting multiple second temperature sensors or multiple sets of third temperature sensors, the control unit can detect the process of the livestock farrowing indicator light being gradually expelled from the livestock body. As the livestock farrowing indicator light is gradually expelled from the livestock body, the control unit gradually increases the brightness of the light source or the flashing frequency. First, it can avoid the livestock from overreacting and allow the livestock to gradually adapt. Second, it can indicate the current urgency to the operator and allow the operator to determine the order of handling when facing multiple livestock farrowing. In addition, it can also prevent the livestock farrowing indicator light based on temperature detection from emitting light at maximum brightness in the initial state, thus saving power consumption.

[0039] (3) This invention utilizes the water content and thermal conductivity of the strip structure of the third temperature sensor as another measure for the control unit to determine whether the livestock farrowing indicator light based on temperature detection has been expelled from the body. Under this measure, it can work even when the external ambient temperature is close to the livestock's body temperature. Therefore, this invention has the advantages of wide applicability and high sensitivity, and can work in various climatic environments and various external environmental conditions.

[0040] (4) In this invention, multiple third temperature sensors are arranged at equal intervals on the same section of the outer surface of the cylindrical capsule body of the livestock farrowing indicator light based on temperature detection. Each temperature sensor includes a heating element and multiple third temperature detection units. In this way, it can work normally even in the external environment, such as when there is moisture on the ground, which further improves its wide applicability. Attached Figure Description

[0068] like Figure 1 As shown, a specific embodiment of the present invention includes a livestock farrowing indicator light based on temperature detection, comprising a light-emitting part 20, a battery 103, and a control unit 102, wherein the control unit 102 is connected to the battery 103 and the light-emitting part 20, and the battery 103 provides power to the light-emitting part 20 and the control unit 102; the livestock farrowing indicator light based on temperature detection has a capsule-shaped structure, with the light-emitting part 20 at one end, followed by a cylindrical capsule body 10, and then a hemispherical tail 21. To facilitate the expulsion of amniotic fluid from the livestock during farrowing, the livestock farrowing indicator light based on temperature detection has a hollow core column 30.

[0069] The livestock farrowing indicator light and method described in this invention are mainly used for detecting farrowing in pigs or other multiparous livestock. For example, a pig's body temperature is typically 38-39.5 degrees Celsius, and the temperature inside the birth canal generally does not fluctuate much. The temperature in a typical farrowing house is 20-22 degrees Celsius. Therefore, there will be a noticeable temperature change after the pig emerges from the birth canal, which the temperature sensor can effectively detect. The control unit then emits an warning light to provide an early warning.

[0070] The cylindrical capsule body 10 has a second temperature sensor 62 on its surface. The second temperature sensor 62 is connected to the control unit 102 and the battery 103 and other necessary structures. Based on the detection result of the second temperature sensor 62, the control unit 102 determines that the livestock farrowing indicator light based on temperature detection has been expelled from the livestock body and controls the light-emitting part 20 to emit a warning light.

[0071] The basic concept of this patent is to first place a capsule-shaped, temperature-detecting livestock farrowing indicator light in the animal's birth canal. This capsule-shaped structure facilitates smooth expulsion during farrowing. The temperature-detecting indicator light enables automatic detection of the animal's farrowing status and process. For example, during automatic detection of farrowing, when the indicator light is expelled from the animal's body, the temperature difference between the animal's body and the ambient temperature causes the second temperature sensor 62 to detect this change. The control unit 102 then controls the light-emitting unit 20 to emit an alarm light. Therefore, this invention has the technical advantages of accurate and reliable detection.

[0072] In addition, in the livestock farrowing indicator light based on temperature detection of the present invention, the front end of the light-emitting part 20 has a flexible extended light-emitting end 50, which is a hollow flexible tube. The flexible extended light-emitting end is disposed outside the livestock body. The flexible extended light-emitting end 50 has a first temperature sensor 61 for detecting the external ambient temperature. The first temperature sensor 61 is connected to the control unit 102 and the battery 103. When the difference between the temperature detected by the second temperature sensor 62 and the external ambient temperature detected by the first temperature sensor 61 is less than a predetermined threshold, the control unit 102 determines that the livestock farrowing indicator light based on temperature detection is discharged from the livestock body and controls the light-emitting part 20 to emit a warning light.

[0073] A control switch can be installed on the flexible extended light-emitting end 50; this control switch can be, for example, manually operated. This setup can serve as a supplementary solution to automatic temperature detection, making it more convenient for operators.

[0074] In a more specific embodiment of the present invention, in order to more accurately detect farrowing, it is necessary to determine the external ambient temperature and use it as a benchmark to compare the temperature detection results of the second temperature sensor 62. Otherwise, the control unit 102 needs to detect the "abrupt change" in the temperature detection results of the second temperature sensor 62, which requires the control unit 102 to record the temperature calculation results of the second temperature sensor 62 for at least a period of time, which is relatively complex to implement. In order to eliminate the need for a storage unit, the external ambient temperature, for example 25 degrees Celsius, can be detected by the first temperature sensor 61 initially set outside the livestock, while the temperature inside the livestock is, for example, 38-39 degrees Celsius. When the temperature detected by the second temperature sensor 52 is also within 25 degrees Celsius plus or minus 2 degrees, the control unit 102 determines that the livestock farrowing indicator light based on temperature detection has been released from the livestock's body and controls the light-emitting part 20 to emit a warning light. In this embodiment, the livestock farrowing indicator light based on temperature detection does not require additional storage data, but only needs to send the detection results of the first temperature sensor 61 and the second temperature sensor 62 to the comparator and use the result of the comparator. Therefore, it has the advantages of simple structure, easy implementation and high stability.

[0075] In addition, in the livestock farrowing indicator light based on temperature detection in a specific embodiment of the present invention, the foremost end of the flexible extended light-emitting end 50 has a ring handle; the first temperature sensor 61 is disposed inside the ring handle, at the rear end of the ring handle.

[0076] As shown in the previous specific embodiment, obtaining accurate external ambient temperature is one of the basic conditions of the technical solution of this invention. To prevent the first temperature sensor 61 from being attached to the animal's body due to the natural drooping of the flexible extended light-emitting end or the animal's squatting or lying down position, thus causing the "external ambient temperature" detected by the first temperature sensor 61 to actually be the animal's body surface temperature, in this specific embodiment of the invention, a ring-shaped handle is provided at the very front end of the flexible extended light-emitting end 50. This ring-shaped handle allows the operator to lift the animal farrowing indicator light based on temperature detection, or serves to suspend the animal farrowing indicator light based on temperature detection. Specifically, the first temperature sensor 61 is positioned inside the ring-shaped handle, so that regardless of the drooping of the flexible extended light-emitting end 50 or the animal's squatting or lying down position, the first temperature sensor 61 will not directly contact the animal's body surface. Furthermore, the first temperature sensor 61 is located at the rear end of the ring-shaped handle, i.e., near the connection point between the flexible extended light-emitting end and the ring-shaped handle. Figure 1 As shown in the specific location, this location will not be held by the operator when lifting the livestock farrowing indicator light based on temperature detection, and the detection result of the first temperature sensor 61 will not be interfered with by the operator, thus protecting the first temperature sensor 61.

[0077] In addition, such as Figure 3 As shown in the specific embodiment of the livestock farrowing indicator light of the present invention, the front end of the capsule-shaped structure of the livestock farrowing indicator light is a hemispherical light-emitting part 20, which is covered by a flexible transparent shell and contains multiple light-emitting elements 201. Multiple second temperature sensors 62 are located at different sections of the cylindrical capsule body surface, for example, one is located near the light-emitting part at the front end and one is located near the tail end 21 at the rear end. The multiple second temperature sensors 62 can detect the temperature separately. The control unit 102 determines the process of the livestock farrowing indicator light being expelled from the livestock body based on different time intervals when the difference between the temperature detected by the second temperature sensors 62 at different sections and the external ambient temperature detected by the first temperature sensor 61 is less than a predetermined threshold. Based on the process of the livestock farrowing indicator light being expelled from the livestock body, the control unit controls some or all of the multiple light-emitting elements 201 to emit warning light, that is, controls the light intensity of the light-emitting part 20.

[0078] To further improve the detection accuracy and flexibility of the present invention, and to provide a more flexible warning mechanism, in this specific embodiment, multiple second temperature sensors 62 are located at different sections on the front and rear of the cylindrical capsule body 10. These second temperature sensors 62 can each detect temperature information. Because the livestock farrowing indicator light based on temperature detection is gradually expelled from the livestock's body, the outermost (frontmost) second temperature sensor 62 can first detect the temperature near the external ambient temperature. As the expulsion process progresses, the other second temperature sensors 62 can also gradually detect the temperature near the external ambient temperature. For example, t1, t2, ..., tn are the time points when the temperature detected by each second temperature sensor differs from the external ambient temperature by less than a predetermined difference. Figure 3 As shown. In this way, the control unit can determine the dynamic process of the temperature-detection-based livestock farrowing indicator light being expelled from the livestock's body. In the initial stage of expulsion, the control unit 102 controls a small number of light-emitting elements 201 to emit light. In the later stage, the control unit 102 controls a large number, or even all, of the light-emitting elements 201 to emit light. The purpose of this setting is to avoid emitting strong light in the initial stage of expulsion, which could cause an overreaction in the livestock or other animals, while in the later stage, the indicator light needs to emit stronger light for a more obvious warning effect.

[0079] in addition, Figure 2 This is a schematic diagram of the structure of four third pressure sensors 63 in a livestock farrowing lamp according to a specific embodiment of the present invention. Figure 2 As shown in the figure, the livestock farrowing indicator light based on temperature detection in a specific embodiment of the present invention also includes a third temperature sensor 63. Figure 2 It includes four third temperature sensors, namely 631, 632 and 633.

[0080] The third temperature sensor 63 is connected to the control unit 102 and the battery 103. When the difference between the external ambient temperature detected by the first temperature sensor 61 and the internal temperature of the livestock is less than a predetermined threshold, the control unit 102 activates the third temperature sensor 63 for detection. The third temperature sensor 63 is disposed on the outer surface of the cylindrical capsule body 10 and includes a strip structure bent into the outer contour of the cross-section of the cylindrical capsule body. The strip structure is filled with a porous filler 6313, which encloses a heating element 6311 and multiple third temperature detection units 6312. The first third temperature detection unit 6312 is in close contact with the heating element 6311, and the other third temperature detection units 6312 are spaced apart from the first third temperature detection unit 6312 along the length of the strip structure. The heating element 6311 and the multiple third temperature detection units 6312 are all connected to the control unit and the battery. The control unit 102 controls the heating element 6311 to activate the third temperature detection unit 6312 within a detection sub-cycle of a detection cycle. The heating element 6311 generates heat. The first third temperature detection unit 6312 detects the temperature of the heating element 6311. When the temperature reaches the first predetermined temperature, the control unit 102 controls the heating unit 6311 to stop heating. When the temperature is lower than the first predetermined temperature by more than a predetermined difference, the control unit 102 controls the heating unit 6311 to continue heating. During this detection sub-cycle, when other third temperature detection units 6312 detect that the temperature has reached the second predetermined temperature, the control unit 102 records the time difference between ...

[0081] In specific embodiments of the present invention, it is necessary to ensure that the livestock farrowing indicator light based on temperature detection has a wider range of applicability. For example, during the summer when livestock are farrowing, the external environment may also reach near the livestock's body temperature, such as 36-40 degrees Celsius. At this time, whether the "sudden change" in temperature is directly detected by the second temperature sensor 62, or the difference between the detection results of the first temperature sensor 61 and the second temperature sensor 62 is used, it is impossible to obtain accurate results. The temperature detection is no longer sensitive. Therefore, the livestock farrowing indicator light based on temperature detection is difficult to play the role of emitting warning light based on the state of the livestock being expelled from the body.

[0082] To address this issue, in this specific embodiment of the invention, a third temperature sensor 63 is used as a supplement for this special case. When the difference between the external ambient temperature detected by the first temperature sensor 61 and the livestock's body temperature is significant, it is not necessarily necessary to utilize the result of the third temperature sensor 63. Alternatively, the third temperature sensor 63 can be used as an auxiliary determination method. When the difference between the external ambient temperature detected by the first temperature sensor 61 and the livestock's body temperature is small, the control unit 102 activates the third temperature sensor 63, and determines, based on the detection result of the third temperature sensor 63, that the temperature-based livestock farrowing indicator light has been released from the livestock's body.

[0083] The working principle of the third temperature sensor 63 is as follows: The third temperature sensor 63 is disposed on the outer surface of the cylindrical capsule body 10, including a strip structure bent into the outer contour of the cross-section of the cylindrical capsule body. The strip structure is filled with a porous filler 6313, which encapsulates a heating element 6311 and multiple third temperature detection units 6312. The porous filler 6313, such as sponge or foam, has a water-absorbing effect. When the temperature-detecting livestock farrowing indicator light is located inside the livestock, the porous filler 6313 can absorb the surrounding moisture. At this time, the thermal conductivity of the porous filler 6313 is close to that of water, thus exhibiting good thermal conductivity and thermal convection.

[0084] The third temperature sensor 63 has a detection cycle, which is divided into a detection sub-cycle and a cooling sub-cycle. In the detection sub-cycle, the control unit 102 first controls the heating element 6311 to generate heat. The first third temperature detection unit 6312 is in close contact with the heating element and detects its temperature. When a first predetermined temperature is reached, this temperature is set to be higher than both the ambient temperature and the animal's body temperature. The heating element 6311 then stops heating. When the temperature drops below the first predetermined temperature by more than a predetermined difference, the control unit 102 controls the heating element 6311 to continue heating. Thus, throughout the entire detection sub-cycle, the first third temperature detection unit 6312 fluctuates around a relatively constant temperature. This constant temperature can be set as needed; for example, if the ambient temperature is 36 degrees Celsius, this constant temperature can be set to 43 degrees Celsius. As mentioned earlier, when the temperature-detecting livestock farrowing indicator light is located inside the birth canal, because the pores of the porous filler 6313 are filled with moisture, heat can be smoothly transferred along the strip structure of the third temperature sensor 63. The temperature detected by the second third temperature detection unit 6312 can also quickly increase, for example, reaching the second predetermined temperature—41 degrees Celsius; subsequently, the temperature detected by the third third temperature detection unit can also quickly increase, for example, also reaching the second predetermined temperature—41 degrees Celsius. The control unit 102 records the time difference between each subsequent third temperature detection unit 6312 detecting a temperature of 41 degrees Celsius and the previous third temperature detection unit 6312 detecting a temperature of 41 degrees Celsius. For example, Figure 4 As shown, the second third temperature detection unit 6312 detects a temperature of 41 degrees Celsius, and the time difference between the second and first third temperature detection units 6312 detecting a temperature of 41 degrees Celsius is dt1. The third third temperature detection unit 6312 detects a temperature of 41 degrees Celsius, and the time difference between the second and third third temperature detection units 6312 detecting a temperature of 41 degrees Celsius is dt2. The control unit 102 can determine the overall thermal conductivity of the strip structure of the third temperature sensor 63 based on the values ​​of dt1 and dt2, and thus infer whether the third temperature sensor 63 (and the livestock farrowing indicator light based on temperature detection) is located inside or outside the livestock.

[0085] If dt1 and / or dt2 are small, for example, less than 30 seconds, the control unit 102 determines that the third temperature sensor 63 is still inside the livestock. After the detection sub-cycle ends, a cooling sub-cycle is initiated to cool the heating element 6311 and the entire strip structure, so that detection can resume when the next detection cycle arrives. The cooling sub-cycle can be set to a length significantly longer than the detection sub-cycle.

[0086] It should be noted that, to prevent the heat emitted by the heating element 6311 from being directly transferred to the surrounding environment of the birth canal, which would prevent the second and third temperature detection units 6312 from detecting temperatures such as 41 degrees Celsius, a heat-insulating film can be covered a portion of the outer surface of the third temperature sensor 63. This is particularly true for the outer surfaces of the heating element 6311 and each temperature detection unit 6312, leaving other surface areas in contact with the outside. In this way, the heat detected by each third temperature detection unit 6312 originates primarily from the longitudinal direction of the strip structure; the heat emitted by the heating element 6311 will also be primarily transmitted along the longitudinal direction of the strip structure.

[0087] When the livestock farrowing indicator light based on temperature detection is expelled from the animal's body, due to the squeezing effect of the birth canal, the drying effect of the external environment, and the evaporation effect of the heating element 6311, the moisture in the porous filling material 6313 is rapidly expelled. At this time, the porous filling material 6313 can no longer maintain good heat conduction and heat convection capacity. Assuming that within the detection sub-cycle, the time difference between the second third temperature detection unit 6312 reaching 41 degrees Celsius and the first third temperature detection unit 6312 reaching 41 degrees Celsius is dt1, and the time difference between the third third temperature detection unit 6312 reaching 41 degrees Celsius and the second third temperature detection unit 6312 reaching 41 degrees Celsius is dt2, then dt1 and dt2 will be longer, exceeding the predetermined length, or even exceeding the length of the detection sub-cycle. Figure 5 As shown. That is to say, during the detection sub-cycle, the second or third temperature detection unit 6312 may not be able to detect a temperature of 41 degrees Celsius. At this time, the control unit 102 determines, based on the extension of dt1 and dt2, that the third temperature sensor 63 has been expelled from the animal's body and begins to control the light-emitting part 20 to emit light.

[0088] Therefore, the specific embodiments of the present invention ingeniously utilize the moisture content of the porous filler to determine whether the temperature-detection-based livestock farrowing indicator light has been expelled from the livestock's body. Thus, the present invention can overcome the problem that the temperature-detection-based livestock farrowing indicator light is difficult to work due to the proximity of the external ambient temperature and the livestock's body temperature, making the temperature-detection-based livestock farrowing indicator light in the specific embodiments of the present invention more widely applicable.

[0089] In addition, such as Figure 2As shown in the specific embodiment of the livestock farrowing indicator light based on temperature detection of the present invention, multiple third temperature sensors 631, 632, 633 and 634 are arranged at equal intervals along the circumference on the same section of the outer surface 101 of the cylindrical capsule body 10. Each temperature sensor 63 includes a heating element and multiple third temperature detection units. The outer surface 101 of the cylindrical capsule body 10 has multiple curved grooves corresponding to the sections of the third temperature sensors 62, and one third temperature sensor 63 is arranged in each curved groove. The bottom and sides of the curved grooves are made of heat-insulating material. The outer surface of the strip structure of the third temperature sensor 63 is flush with the outer surface of the cylindrical capsule body 10. The multiple third temperature sensors 63 are all connected to the control unit 102 and the battery 103. The control unit 102 determines that the livestock farrowing indicator light based on temperature detection is expelled from the livestock body based on the time difference between the temperature detected by each of the other third temperature detection units 6312 among the multiple sensors 63 reaching the second predetermined temperature and the temperature detected by the previous third temperature detection unit 6312 reaching the second predetermined temperature, and controls the light-emitting part 20 to emit a warning light.

[0090] There is another special case to consider: after the temperature-detecting livestock farrowing indicator light is expelled and falls to the ground, where there is moisture, this moisture can be absorbed into the strip-shaped structure of the third temperature sensor 63. This special case renders the aforementioned method of determining whether the temperature-detecting livestock farrowing indicator light has been expelled from the livestock body by changing the moisture content of the porous filler 6313 ineffective. Therefore, in this specific embodiment of the invention, multiple third temperature sensors 63 are arranged at equal intervals along the circumference on the same section of the outer surface 101 of the cylindrical capsule body 10, for example, according to... Figure 2 In this system, four third temperature sensors 63 are set at 90-degree intervals. According to the above operation, any longer dt1 or dt2 detected by any of the third temperature sensors 63 can be used as a basis for determining that the livestock farrowing indicator light based on temperature detection has been expelled from the livestock's body.

[0091] Specifically, the outer surface 101 of the cylindrical capsule body 10 has multiple curved grooves corresponding to the section of the third temperature sensor 63. Each curved groove is equipped with a third temperature sensor 63. The bottom and sides of the curved groove are made of heat-insulating material, which ensures that heat is transferred along the length of the strip structure of the third temperature sensor 63 and is not transferred into the cylindrical capsule body.

[0092] Furthermore, in the livestock farrowing indicator light based on temperature detection according to a specific embodiment of the present invention, in each of the multiple segments on the outer surface 101 of the cylindrical capsule body 10, a plurality of third temperature sensors 63 are arranged at equal intervals along the circumference. Each temperature sensor 63 includes a heating element 6311 and a plurality of third temperature detection units 6312. The plurality of third temperature sensors 63 are all connected to the control unit 102 and the battery 103. The control unit 102 determines the process of the livestock farrowing indicator light being expelled from the livestock body based on the detection results of the plurality of third temperature sensors 63 in each of the multiple segments, and controls the brightness of the light-emitting part 20 based on the process of the livestock farrowing indicator light being expelled from the livestock body.

[0093] The status of the livestock farrowing indicator light based on temperature detection is determined using a third temperature sensor 63. Multiple sections can be set, with four third temperature sensors 63 installed in each section. Following a similar principle to the previous embodiment, the control unit can determine the dynamic process of the livestock farrowing indicator light being expelled from the livestock. In the initial stage of expulsion, the control unit 102 controls a small number of light-emitting elements 201 to emit light. In the later stage, the control unit 102 controls a large number of light-emitting elements 201 to emit light, thus increasing the overall luminous intensity of the light-emitting part 20.

[0094] Corresponding to the livestock farrowing indicator light based on temperature detection in the specific embodiments of the present invention, the specific embodiments of the present invention also include a livestock farrowing indicator method based on temperature detection, the method comprising the following steps:

[0095] A. Detect the external temperature using a first temperature sensor installed on the outside of the livestock;

[0096] B. Temperature is detected using a second temperature sensor on the cylindrical capsule body of the livestock farrowing indicator light based on temperature detection;

[0097] C. When the difference between the temperature detected by the second temperature sensor and the external ambient temperature detected by the first temperature sensor is less than a predetermined threshold, it is determined that the livestock farrowing indicator light based on temperature detection has been expelled from the livestock's body, and the light-emitting part is controlled to emit a warning light.

[0098] Furthermore, in the livestock farrowing alert method based on temperature detection according to a specific embodiment of the present invention, multiple second temperature sensors are provided at different positions on the front and back of the surface of the cylindrical capsule body, and the multiple second temperature sensors detect the temperature respectively; the control unit determines the process of the livestock farrowing alert light being expelled from the livestock body at different times based on the temperature difference between the second temperature sensor at different positions and the external ambient temperature detected by the first temperature sensor being less than a predetermined threshold, and controls the luminous intensity of the light-emitting part based on the process of the livestock farrowing alert light being expelled from the livestock body.

[0099] Furthermore, in the livestock parturition alert method based on temperature detection in a specific embodiment of the present invention, when the difference between the external ambient temperature detected by the first temperature sensor and the internal temperature of the livestock is less than a predetermined threshold, the following operations are performed:

[0100] B01. The control unit activates the third temperature sensor;

[0101] B02. Within a detection cycle, in a detection sub-cycle, the control unit controls the heating element of the third temperature sensor to generate heat. The first third temperature detection unit detects the temperature of the heating element. When the first predetermined temperature is reached, the heating unit stops heating. When the temperature is lower than the first predetermined temperature by more than the difference, the heating unit continues to heat.

[0102] B03. In this detection sub-cycle, when the temperature detected by other third temperature detection units of the third temperature sensor reaches the second predetermined temperature, the control unit records the time difference between the temperature detected by the third temperature detection unit reaching the second predetermined temperature and the temperature detected by the previous third temperature detection unit reaching the second predetermined temperature, in order to determine whether the livestock farrowing indicator light based on temperature detection has been expelled from the livestock. If the result is no, the control unit waits for the cooling sub-cycle before proceeding to the next detection cycle and repeats steps B02 and B03.

[0103] B04. If the result is confirmed to be yes, then control the light-emitting part to emit a warning light.

[0104] In summary, the technical effects of the specific embodiments of the present invention include the following.

[0105] (1) In the livestock farrowing indicator light based on temperature detection of the present invention, the temperature detection result is innovatively used as the basis for judging whether the livestock farrowing indicator light based on temperature detection has been expelled from the livestock body. Therefore, the livestock farrowing indicator light based on temperature detection does not need a moving unit and does not need to be deformed. The detection is convenient and flexible. Because temperature sensors are widely used, they have the advantages of simple selection and high sensitivity.

[0106] (2) In the livestock farrowing indicator light based on temperature detection of the present invention, by setting multiple second temperature sensors or multiple sets of third temperature sensors, the control unit can detect the process of the livestock farrowing indicator light being gradually expelled from the livestock body. As the livestock farrowing indicator light is gradually expelled from the livestock body, the control unit gradually increases the brightness of the light source or the flashing frequency. First, it can avoid the livestock from overreacting and allow the livestock to gradually adapt. Second, it can indicate the current urgency to the operator and allow the operator to determine the order of handling when facing multiple livestock farrowing. In addition, it can also prevent the livestock farrowing indicator light based on temperature detection from emitting light at maximum brightness in the initial state, thus saving power consumption.

[0107] (3) This invention utilizes the water content and thermal conductivity of the strip structure of the third temperature sensor as another measure for the control unit to determine whether the livestock farrowing indicator light based on temperature detection has been expelled from the body. Under this measure, it can work even when the external ambient temperature is close to the livestock's body temperature. Therefore, this invention has the advantages of wide applicability and high sensitivity, and can work in various climatic environments and various external environmental conditions.

[0108] (4) In this invention, multiple third temperature sensors are arranged at equal intervals on the same section of the outer surface of the cylindrical capsule body of the livestock farrowing indicator light based on temperature detection. Each temperature sensor includes a heating element and multiple third temperature detection units. In this way, it can work normally even in the external environment, such as when there is moisture on the ground, which further improves its wide applicability.
