Description

Technical Field

[0001] The invention relates to the technical field of pig breeding, and in particular to an integrated water feeder and a use method thereof. Background Art

[0002] my country is the world's largest producer of live pigs, and pork is the largest consumer product for residents. Changes in body temperature are an indicator of whether a pig has a disease, and temperature monitoring is one of the indispensable bases for diagnosing pig diseases. The construction of a pig health management system to monitor pig body temperature online and provide timely warnings is an important support for improving the ability to resist epidemic risks and market risks.

[0003] The traditional method of measuring pig body temperature generally uses rectal temperature measurement. This method is difficult to operate and can only measure once. It cannot monitor the body temperature data in real time, making it impossible for farmers to take effective measures and prevent health problems of pigs in the first place. In recent years, Chinese scientific and technological workers have done a lot of research on pig body temperature monitoring. Most of the domestic research is on thermal imaging equipment temperature measurement and electronic ear tag temperature measurement. Among them, infrared temperature measurement equipment can be divided into: handheld, fixed and rail type. The advantage of handheld is low cost. Only one device is needed for a pig shed. The disadvantage is that manual participation in temperature measurement is required and automatic operation cannot be provided. This frequent manual entry into the breeding environment may bring uncertain external pollution to pig breeding. The advantage of fixed thermal imagers and rail thermal imagers for temperature measurement is that they can monitor pig body temperature in real time and unmanned, but their biggest disadvantage is the high deployment cost. Although the research on these innovative temperature measurement technologies can indeed greatly improve the efficiency of temperature measurement, the cost of thermal imaging temperature measurement technology and electronic ear tags is relatively high. Moreover, none of the research on thermal imaging temperature measurement technology can directly mark pigs with abnormal temperatures. Therefore, if an abnormal temperature of a pig is found, manpower is still needed to find it, which is time-consuming and labor-intensive. Summary of the invention

[0004] The first object of the present invention is to provide an integrated water feeder, which aims to solve the technical problems that the existing pig temperature measuring devices are high in cost and cannot mark pigs with abnormal temperatures.

[0005] In order to solve the above technical problems, an integrated water feeder is provided, comprising:

[0006] Water feeder body;

[0007] A temperature measuring component, disposed at the outlet end of the water feeder body, for obtaining real-time temperature data of the target object's oral cavity;

[0008] marker;

[0009] The controller is electrically connected to the marker and the temperature measuring component respectively, and is configured as follows: the controller processes the real-time temperature data and obtains a real-time temperature value, and when the real-time temperature value exceeds a preset threshold, controls the marker to spray a marking liquid toward the target object.

[0010] Furthermore, the temperature measuring component includes a shell and a temperature sensor, the shell is connected to the water feeder body, the temperature sensor is arranged in the shell, and the temperature sensor is electrically connected to the controller.

[0011] Furthermore, the temperature measurement component also includes a conductive member, the conductive member forms a receiving cavity, and the temperature sensor is arranged in the receiving cavity and abuts against the inner wall of the receiving cavity.

[0012] Furthermore, the temperature measuring component also includes a cover body, which is connected to the conductive member and covers the opening of the accommodating cavity.

[0013] Furthermore, the shell includes a connecting portion, the water feeder body includes a connecting head, and the connecting portion is connected to the connecting head to install the temperature measuring component on the water feeder body.

[0014] Furthermore, the water feeder body also includes a valve core and a sealing ring, the valve core is arranged in the shell, and the sealing ring is arranged between the valve core and the shell.

[0015] Furthermore, the waterer body sprays feeding liquid along a first direction, and the marker sprays marking liquid along a second direction, and a preset angle is formed between the first direction and the second direction.

[0016] A second object of the present invention is to provide a method for using an integrated water feeder, which is applied to the above-mentioned integrated water feeder, and the method comprises:

[0017] Set the target object's temperature preset threshold;

[0018] Obtain real-time temperature data of the target's oral cavity;

[0019] The real-time temperature data is processed to obtain a real-time temperature value, and when the real-time temperature value exceeds a preset threshold, the marker is controlled to spray a marking liquid toward the target object.

[0020] Furthermore, the temperature measuring component is controlled to obtain real-time temperature data for multiple consecutive times. After obtaining the real-time temperature data of the target object's mouth, the controller performs a smoothing filter algorithm on the real-time temperature data to obtain the real-time temperature value. If the three consecutive real-time temperature values ​​obtained all exceed a preset threshold, the marker is controlled to spray marking liquid toward the target object.

[0021] Furthermore, if n real-time temperature data are measured within the i-th second, the output temperature value of the i-th second is The time and temperature data of the 1st, 2nd, 3rd, ... mth seconds are obtained as follows: After processing, the real-time temperature values ​​T1, T2...T m .......

[0022] Implementing the embodiments of the present invention will have the following beneficial effects:

[0023] The integrated water feeder in this embodiment integrates the water feeder body, the temperature measuring component and the marker into one body. When the pig drinks water, the oral temperature of the pig is automatically measured, the temperature measuring component accurately obtains the pig's body temperature, and the controller collects and processes the pig's body temperature to determine whether the pig has an abnormal body temperature. Taking advantage of the fact that the pig uses its upper jaw to support the water feeder when drinking water, the body temperature of the pig group is monitored while feeding water. When the pig's body temperature exceeds the normal value, the marker automatically sprays harmless marking liquid for easy identification, so as to achieve the purpose of disease prevention and control. It is beneficial to reduce the cost of the pig temperature measuring device, and at the same time realize real-time, unmanned monitoring of the pig's body temperature.

The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] Please refer to Figure 1-Figure 5The embodiment of the present invention provides an integrated water feeder 100, including a water feeder body 110, a temperature measuring component 120, a marker 130 and a controller 140. The temperature measuring component 120 is arranged at the outlet end of the water feeder body 110, and is used to obtain the real-time temperature data of the target object's mouth; the controller 140 is electrically connected to the marker 130 and the temperature measuring component 120 respectively, and the controller 140 is configured as follows: the controller 140 processes the real-time temperature data and obtains the real-time temperature value, and when the real-time temperature value exceeds the preset threshold, the marker 130 is controlled to spray the marker liquid to the target object. Exemplarily, the integrated water feeder 100 of the present application is applied to pig breeding, and of course, it can also be applied to other animal husbandry breeding farms. The water feeder body 110 is connected to the first storage box through a pipeline, and the marker 130 is connected to the second storage box through a pipeline. The first storage box is used to store water or other nutrient solution for feeding pigs, and the second storage box is used to store the marker liquid. The marking liquid is configured as a liquid that is easily identifiable by the staff and harmless to the pigs. For example, the marking liquid can be a mixed liquid with a color. When the marking liquid is sprayed on the pigs, the staff can clearly see the mark. When the pigs drink water, they bite the integrated water feeder 100. At this time, the upper jaw of the pigs presses against the temperature measuring component 120. At this time, the temperature measuring component 120 can measure the temperature of the pigs' oral cavity.

[0036] Please refer to Figure 2 , Figure 3 and Figure 4 The integrated water feeder 100 in this embodiment integrates the water feeder body 110, the temperature measuring component 120 and the marker 130. When the pig drinks water, the oral temperature of the pig is automatically measured, the temperature measuring component 120 accurately obtains the pig's body temperature, and the controller 140 collects and processes the pig's body temperature to determine whether the pig has an abnormal body temperature. Taking advantage of the characteristic that the pig uses the upper jaw to support the water feeder when drinking water, the body temperature of the pig group is monitored while feeding water. When the pig's body temperature exceeds the normal value, the marker 130 automatically sprays harmless marking liquid for easy identification, so as to achieve the purpose of disease prevention and control. It is beneficial to reduce the cost of the pig temperature measuring device, and at the same time realize real-time, unmanned monitoring of the pig's body temperature.

[0037] Traditional methods of monitoring pig body temperature mainly include mercury thermometers, electronic thermometers, infrared temperature measurement, etc. Although this temperature measurement method is low-cost, it is inefficient, labor-intensive, and difficult to achieve online monitoring of pig body temperature. Intelligent temperature measurement, such as rail-type infrared thermal imaging measurement, wheel-type infrared measurement, electronic ear tag measurement, etc., has unchanged installation, high cost, complex maintenance technology, and heavy workload.

[0038] The present application embeds a temperature sensor 122 into an existing pig watering device. When the pig drinks water, the oral temperature of the pig is automatically measured to accurately obtain the pig's body temperature. When the pig's body temperature exceeds the normal value, a harmless marking liquid is automatically sprayed for easy identification to achieve the purpose of disease prevention and control. The integrated water feeder 100 of the present application can solve the problems of low efficiency and difficulty of handheld measuring equipment, and difficulty in realizing online monitoring of pig body temperature in large pig farms, as well as the problems of inconvenient installation of automated measuring equipment, high cost, complex maintenance technology, and heavy workload.

[0039] The cost of existing more advanced temperature measurement technologies, such as thermal infrared pig body temperature measurement equipment and electronic ear tags, is relatively high, and the maintenance cost is also high. For some small pig farms, it may increase the economic burden, so it cannot be used on a large scale. The integrated waterer 100 of the present application is based on the original traditional pig breeding waterer, which is modified by embedding a temperature sensor 122 at the traditional water feeding nozzle switch, and then integrating a marker 130. The cost of the temperature sensor 122 is relatively low on the market, and the marker 130 is just a device similar to a nozzle, so the cost of the marker 130 is relatively low. So in general, the cost of modifying the waterer will be relatively low.

[0040] At present, most of the research on advanced temperature measurement technologies, such as thermal imaging temperature measurement technology, do not have the function of directly marking pigs with abnormal temperatures. So, if a pig's body temperature is found to be abnormal, manpower is still needed to find it, which is time-consuming and laborious. The integrated waterer 100 of the present application can immediately mark the pigs with abnormal temperatures after an abnormal body temperature warning for large live pigs, thereby improving the scientificity and efficiency of breeding management. When the waterer is modified, the marker 130 is integrated into the pipe of the waterer, so that an early warning will be issued when it is judged that the body temperature is abnormal, that is, the switch of the marker 130 is linked to the early warning. When an early warning appears, the switch of the marker 130 will automatically turn on and spray pollution-free marking liquid on the pig's forehead for easy identification, thereby realizing the early warning marking function.

[0041] Please refer to Figure 2 , Figure 3 and Figure 4In a possible implementation, the temperature measuring component 120 includes a shell 121 and a temperature sensor 122. The shell 121 is connected to the water feeder body 110. The temperature sensor 122 is disposed in the shell 121. The temperature sensor 122 is electrically connected to the controller 140. Exemplarily, the shell 121 is used to protect the temperature sensor 122, which is beneficial to prolonging the service life of the temperature sensor 122 and prolonging the service life of the integrated water feeder 100. The shell 121 and the water feeder body 110 may be fixedly connected or detachably connected. In this embodiment, the temperature measuring component 120 is detachably mounted on the water feeder body 110. When the temperature measuring component 120 is damaged, the user can replace the new temperature measuring component 120, which is convenient for installation and maintenance. The temperature sensor 122 may be a contact type or a non-contact type.

[0042] Please refer to Figure 2 , Figure 3 and Figure 4 In a possible embodiment, the temperature measuring component 120 further includes a conductive member 123, the conductive member 123 is formed with a housing cavity 1231, and the temperature sensor 122 is arranged in the housing cavity 1231 and abuts against the inner wall of the housing cavity 1231. Exemplarily, the temperature in the oral cavity of the live pig is transmitted to the temperature sensor 122 through the conductive member 123. It can be understood that the conductive member 123 should be made of a material with a high thermal conductivity. In addition, the conductive member 123 can also protect the temperature sensor 122. The function of the conductive member 123 is to transmit the temperature of the oral cavity of the pig. Specifically, when the live pig drinks water, its upper jaw will contact the conductive member 123. At this time, the temperature of the oral cavity of the pig is heat-transferred through the conductive member 123, so that the temperature sensor 122 can sensitively measure the temperature of the oral cavity of the pig. This process ensures the accuracy and real-time performance of temperature measurement, which is crucial for monitoring the body temperature of the live pig and detecting abnormalities in a timely manner.

[0043] Please refer to Figure 2 , Figure 3 and Figure 4 In a possible implementation, the temperature measuring assembly 120 further includes a cover 124, which is connected to the conductive member 123 and covers the opening of the accommodating cavity 1231. Exemplarily, the cover 124 is made of a waterproof and anti-corrosion material, and the function of the cover 124 is to protect the temperature sensor 122 from the influence of a humid environment and to prevent external factors such as pig saliva from corroding the water feeder. By using the cover 124 made of a waterproof and anti-corrosion material, it is ensured that the temperature sensor 122 can work normally in a humid environment, especially when the pigs are drinking water, thereby maintaining the stability and reliability of the temperature measuring system.

[0044] Please refer to Figure 2 , Figure 3 and Figure 4In a possible implementation, the housing 121 includes a connecting portion 1211, and the water feeder body 110 includes a connecting head 111, and the connecting portion 1211 is connected to the connecting head 111 to install the temperature measuring component 120 on the water feeder body 110. Exemplarily, the connecting head 111 is provided with an external thread, and the connecting portion 1211 is provided with an internal thread, and the connecting head 111 and the housing 121 are detachably connected through a threaded connection.

[0045] Please refer to Figure 2 , Figure 3 and Figure 4 In a possible implementation, the water feeder body 110 further includes a valve core 112 and a sealing ring 113, the valve core 112 is disposed in the housing 121, and the sealing ring 113 is disposed between the valve core 112 and the housing 121. Exemplarily, the water feeder body 110 used in the present application uses a duckbill type pig drinking water device, which is mainly composed of a valve body, a valve core 112, a sealing ring 113, a return spring, a plug cover, a filter screen, etc. The valve body and the valve core 112 are made of brass and stainless steel, the spring and the filter screen are made of stainless steel, and the plug cover is made of engineering plastics. The overall structure is simple, corrosion-resistant, reliable, water-tight and has a long service life. When a pig drinks water, it holds the waterer in its mouth and bites down on the valve stem, and water flows out from the gap between the valve core 112 and the sealing ring 113 and enters the pig's mouth. When the pig's mouth is loosened, the valve stem is reset by the tension of the return spring, the water outlet gap is closed, and the water stops flowing out. The duckbill pig drinking water equipment has good sealing performance, the pressure is reduced when water flows out, and the flow rate is low, which meets the pig's drinking water requirements.

[0046] In addition, it should be noted that the valve core 112 is connected to the conductive member 123. When the pig drinks water, the upper jaw of the pig's mouth abuts against the conductive member 123. At this time, the conductive member 123 presses downward to push the valve core 112 open, and water flows out of the integrated water feeder 100. At this time, the pig can drink water. In other words, the conductive member 123 has three functions. The first is to conduct heat, the second is to protect the temperature sensor 122, and the third is to serve as a water drinking switch. The main invention of the integrated water feeder 100 of the present application is that the temperature sensor 122 is embedded in the switch of the original water feeder.

[0047] Please refer to Figure 2In a possible implementation, the water feeder body 110 sprays the feeding liquid along the first direction X, and the marker 130 sprays the marking liquid along the second direction Y, and a preset angle α is formed between the first direction X and the second direction Y. Exemplarily, the feeding liquid can be water, or a mixed liquid with other nutrient elements added. In this embodiment, the preset angle α is set to 45°. Of course, in specific applications, the angle setting of the preset angle α is not limited thereto. For example, as an alternative, the preset angle α can be set within the range of [30°, 60°] according to actual needs, and the preset angle α can also be set to 30°, or 35°, or 40°, or 50°, or 55°, or 60°.

[0048] Please refer to Figure 5 and Figure 6 The second object of the present invention is to provide a method for using the integrated water feeder 100, which is applied to the above-mentioned integrated water feeder 100, and the method includes:

[0049] Set the target object's temperature preset threshold;

[0050] Obtain real-time temperature data of the target's oral cavity;

[0051] The real-time temperature data is processed to obtain a real-time temperature value. When the real-time temperature value exceeds a preset threshold, the marker 130 is controlled to spray a marking liquid toward the target object.

[0052] Please refer to Figure 5 and Figure 6 In a possible implementation, the temperature measuring component 120 is controlled to obtain real-time temperature data for multiple consecutive times. After obtaining the real-time temperature data of the target object's oral cavity, the controller 140 performs a smoothing filter algorithm on the real-time temperature data to obtain a real-time temperature value. If the three consecutive real-time temperature values ​​obtained all exceed the preset threshold, the marker 130 is controlled to spray a marking liquid toward the target object. Exemplarily, the real-time acquisition collects n real-time temperature data per second. The advantage of using a smoothing filter algorithm to process data is that it can improve the accuracy and reliability of data processing. Specifically, the smoothing filter algorithm reduces the noise caused by accidental fluctuations, making the temperature data collected from the temperature sensor 122 smoother and more stable. This processing method helps to more accurately reflect the actual body temperature changes of the pig, thereby reducing misjudgments caused by data fluctuations. In addition, the smoothing filter algorithm can also effectively filter out the interference of instantaneous high or low temperatures, ensuring that the real-time temperature value outputted is more accurate, providing a reliable basis for subsequent temperature abnormality judgments.

[0053] In addition, the benefit of judging that the pig's body temperature is abnormal only when three consecutive real-time temperature values ​​exceed the preset threshold is that it improves the accuracy and reliability of the diagnosis. Specifically, through this multiple sampling and verification method, the misjudgment caused by accidental fluctuations or instantaneous high / low temperatures can be effectively reduced. This method ensures that the marker 130 will be triggered for marking only when the pig's body temperature is indeed continuously abnormal, thereby avoiding unnecessary waste of resources and management problems. Through multiple sampling and verification, misjudgments caused by accidental fluctuations are reduced, and the accuracy of abnormal body temperature judgment is improved. Misjudgments caused by instantaneous high or low temperatures are avoided, the false alarm rate is reduced, and the early warning system is more reliable. The marker 130 is triggered only when the body temperature is indeed abnormal, avoiding unnecessary waste of resources, such as the use of harmless marking liquids. The frequency of manual searches for pigs with abnormal body temperatures is reduced, and the scientificity and efficiency of breeding management are improved. Of course, in specific applications, it can also be set that as long as one real-time temperature value exceeds the preset threshold, it is judged as the pig's body temperature is abnormal, or two consecutive real-time temperature values ​​exceed the preset threshold to be judged as the pig's body temperature is abnormal, or four consecutive real-time temperature values ​​exceed the preset threshold to be judged as the pig's body temperature is abnormal.

[0054] In a possible implementation, n real-time temperature data are measured within the i-th second, and the output temperature value at the i-th second is The time and temperature data of the 1st, 2nd, 3rd, ... mth seconds are obtained as follows: After processing, the real-time temperature values ​​T1, T2...T m ....... That is, when T j , T j+1 , T j+2 >T0, the controller 140 will control the switch of the marker 130 to turn on, allowing the marker 130 to spray green, pollution-free marking liquid onto the pig's forehead to mark the pig with abnormal temperature. The temperature is corrected after filtering, that is, the final temperature, which is the correction degree (reflecting the influence of water flow). The specific value is determined by experimental testing based on the temperature difference measured in the water state and the water-free state. The moving average filtering method is then used for filtering to obtain the measured temperature. T0 is obtained through research and testing. The temperature measurement error of the integrated water feeder 100 of this application can be controlled at about 5%. The body temperature of the pig can be measured relatively accurately, and pigs with abnormal body temperature can be marked.

[0055] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
