Description

Technical Field

[0001] The utility model relates to the field of animal husbandry, in particular to a device for detecting the nasal cavity temperature of a dairy cow, which is used for detecting relevant physiological states of the dairy cow. Background Art

[0002] Body temperature is an important basis for judging the physiological state and health status of dairy cows. Real-time monitoring of body temperature changes is conducive to monitoring the physiological state of dairy cows, scientifically organizing production, and early detection, diagnosis and treatment of sick cows. However, rectal temperature measurement is often used in the past, which cannot achieve continuous and automatic monitoring, is time-consuming and labor-intensive, and cannot be used for batch monitoring of cattle. Based on the body temperature detection technology of the cow's vagina (document number CN218572182U) and the base of the tail (document number CN204426297U), an automatic body temperature monitoring device was constructed, but vaginal temperature measurement and tail base temperature measurement are harmful to cows and have not been promoted and applied. Thermal infrared technology provides a new direction for automatic monitoring of dairy cow body temperature. Infrared thermal imagers can be installed in the milking channel to realize automatic monitoring of dairy cow body temperature (document number CN214309081U), but it is necessary to drive the cows into the milking channel and measure the temperature of specific parts of the cow's body, and it is impossible to monitor the body temperature of cows that are far away or out of the range of the infrared thermal imager. Summary of the invention

[0003] The utility model aims to provide a device for detecting the nasal cavity temperature of a cow in view of the problems in the prior art.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A cow nasal cavity temperature detection device comprises a detection module, a connecting component and a fixing component. The detection module is used to be placed in the cow's nasal vestibule. The detection module comprises an infrared temperature sensor. The detection module is connected to the fixing component through the connecting component so that the infrared temperature sensor can face the cow's nasal cavity.

[0006] Preferably, it also includes a circuit module connected to the detection module and providing a control signal, and a wireless communication module disposed in the circuit module and connected to the circuit module. The wireless communication module can be a wifi, Bluetooth, Zigbee or other module. Considering the power consumption factor, the wireless communication module is preferably a Zigbee module.

[0007] Preferably, the fixing component comprises a base, a shell is fixed on the base, and the circuit module is located in the shell.

[0008] Preferably, the device further comprises a power supply module connected to the circuit module.

[0009] Preferably, the circuit module is provided with a microcontroller capable of regulating the working state of the circuit module.

[0010] Preferably, the microcontroller has a built-in control program, the microcontroller caches the temperature data in a memory, wakes up the wireless communication module regularly to transmit data, and wakes up the wireless communication module in time to transmit abnormal data when the temperature data is abnormal.

[0011] Preferably, the detection modules are a pair, at least one of which has an infrared temperature sensor, and the connecting component comprises a pair of connecting rods, and the detection modules are connected to the fixing component respectively through the connecting rods.

[0012] Preferably, the detection module is ellipsoidal, one end of the ellipsoid is connected to the connecting component to be fixed, and the other end has a flexible protective material, and the infrared temperature sensor is located on the side facing the fixing component.

[0013] Preferably, there is a rotating shaft between the connecting component and the base, and the connecting rod has an elastic freedom parallel to the rotating shaft and has a tendency to bring the pair of detection modules closer together. That is, the detection modules can be brought closer together by the connecting rod, which helps to fix the detection modules in the nose of the cow. The connection between the connecting rod and the fixing component can be achieved by, for example, a torsion spring.

[0014] Preferably, the base has straps on both sides.

[0015] Preferably, the base has strap holes on both sides, the straps are installed in the strap holes, the inner periphery of the strap holes is provided with toothed protrusions, and the strap holes are also provided with toothed clips that are elastically engaged with the toothed protrusions. More preferably, the base end also has a strap hole and a strap.

[0016] The utility model provides a cow nasal cavity temperature detection device, which adopts an infrared temperature sensor to monitor the cow nasal cavity temperature, and extends into the nasal cavity in the form of a probe (detection module). The infrared temperature sensor does not contact the inner wall of the nasal cavity, and detects by infrared means. Since the nasal cavity body temperature is relatively constant compared with that outside the body, and is also gentler than rectal and vaginal temperature measurement methods, it is easier for cows to accept and stays in the body for a long time, thereby realizing automatic body temperature detection, and can monitor the cow's body temperature in real time and continuously.

[0017] The utility model optimizes various components of the device, for example, uses a ZigBee module as a wireless communication module, and the power consumption in standby mode is only 1.1μA. At the same time, the microcontroller has a built-in control program to cache the normal temperature data in the memory, and transmits the data by timed wake-up. Only when the temperature data is abnormal, the wireless communication module is awakened in time to transmit the abnormal data, which greatly reduces the wake-up frequency and working time of the wireless communication module, and effectively reduces the system power consumption. Therefore, the entire device can be more miniaturized and lightweight, and the wearing comfort of the cow is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The utility model is further described below in conjunction with the accompanying drawings.

[0023] like Figure 1 , Figure 2 As shown, a cow nasal cavity temperature detection device includes a detection module 5, a connecting component 7 and a fixing component. The detection module 5 is used to be placed in the cow's nasal vestibule. The detection module 5 includes an infrared temperature sensor. The detection module 5 is connected to the fixing component through the connecting component 7, so that the infrared temperature sensor can face the cow's nasal cavity.

[0024] The fixing component is used to place and fix the nose bridge at the front end of the cow's head. This place is flat, which is convenient for placing and fixing the equipment. After installing the fixing component, adjust the connecting component 7, and extend the infrared temperature sensor to the front end of the cow's head nasal cavity through the placement of the connecting component 7, and clamp the middle part of the front end of the cow's nose from both sides to fix the cow's nasal cavity temperature detection device from the front end.

[0025] In addition, it also includes a circuit module 1 connected to the detection module 5 and providing a control signal, and a wireless communication module 2 disposed inside the circuit module 1 and connected to the circuit module 1. It also includes a power supply module 4 connected to the circuit module 1.

[0026] like Figure 1 As shown, the circuit module 1 is arranged in the fixed component, and plays the role of controlling power output, transmitting signals, analyzing signals, and sending signals in the overall system. The preliminary system operation control can be realized through the circuit module 1. The wireless communication module 2 is electrically connected to the circuit module 1, and under the arrangement of the circuit module 1, it sends data signals to the outside, so that the real-time monitoring data is transmitted to the receiving device for data recording and data analysis.

[0027] Further, if Figure 1 As shown, a microcontroller 83 is also included. The microcontroller 83 is used to charge the power module 4 set inside. The external power is input into the microcontroller 83. Under the deployment of the microcontroller 83, the power module 4 is charged, and the power module 4 is automatically powered off after being fully charged, so as to realize the charging overload protection of the power module 4.

[0028] The detection module 5 is a detection device in the device for extracting real-time temperature. The detection module 5 directly contacts the part where the temperature is to be measured, and feeds back data in real time. Through the regulation of the circuit module 1, the feedback data is fed back to the background data center through the wireless communication module 2, and the collected data is fed back to realize real-time and accurate data reporting. In this example, the detection module 5 includes an infrared temperature sensor.

[0029] The fixing component includes a base, on which a housing 6 is fixed, and the circuit module 1 is located inside the housing 6 .

[0030] The fixed component is configured as two structures, namely, a base and a shell 6, which can be disassembled and assembled, making it easy to replace and repair the equipment inside the shell 6. Moreover, the function of charging the equipment in turn can be realized by disassembling and replacing.

[0031] The detection modules 5 are a pair, and different sensor devices can be placed in the two detection modules 5. For example, one of them can be installed with an infrared temperature sensor, and the other can be installed with a heart rate sensor or other sensors. The connecting component 7 includes a pair of connecting rods, and the detection modules 5 are connected to the fixed component through the connecting rods. The detection module 5 is ellipsoidal, one end of the ellipsoid is connected to the connecting component 7 to be fixed, and the other end has a flexible protective material, and the infrared temperature sensor is located on the side facing the fixed component. There is a rotating shaft between the connecting component 7 and the base, and the connecting rod has an elastic degree of freedom relative to the rotating shaft away from the relative position of the two connecting components 7.

[0032] The overall cow nasal cavity temperature detection device is wrapped by an outer shell 6 on the outside, and the detection module 5 is supported by a connecting component 7, extending from the outer shell 6 to the part where the temperature needs to be measured, and the connecting rods on both sides converge at the front end of the cow's head nasal cavity, clamping the middle of the cow's nose from both sides, and fixing the front end of the cow's nasal cavity temperature detection device through the connecting rods on both sides, while keeping the detection part of the detection module 5 at the end of the connecting rod facing the nasal cavity of the cow's nose, so as to detect the temperature change inside the cow's nasal cavity, and cooperate to complete the real-time temperature measurement function of the cow's nasal cavity temperature detection device. In addition, the part of the detection module 5 facing the cow's nasal cavity can be set to a rotatable and adjustable structure. After the connecting rods on both sides clamp the cow's nose, the part of the detection module 5 is fine-tuned so that its detection part is accurately aligned with the inside of the cow's nasal cavity.

[0033] One end of the ellipsoidal detection module 5 is connected to the connecting component 7, and the connection is a rigid structure, thereby ensuring that the detection module 5 is firmly connected. The flexible material at the other end is clamped with the bull's nose. The use of flexible material can make it more comfortable when clamping the bull's nose, avoiding damage to the soft tissue at the front end of the bull's nose. In addition, the infrared temperature sensor is located on the side facing the fixed component, ensuring that it can always be aligned with the inside of the bull's nasal cavity to measure the precise temperature value; there is a rotating shaft between the connecting component 7 and the base, and the connecting rod has elastic freedom relative to the rotating shaft, thereby ensuring that the connecting component 7 can be compressed and moved within a certain range, ensuring that the device will not fall off when the bull's head moves.

[0034] The connecting component 7 and the rotating shaft can be pulled from the middle part by a spring, or a coil spring sleeved on each rotating shaft to push the rotating shaft to form a rotating force can be installed, and each rotating shaft is separately installed with a coil spring so that they can operate independently without affecting each other. The function of the spring and the coil spring is to make the connecting components 7 on both sides converge to the middle area, thereby clamping the front end of the cow's nose and keeping the front end of the cow's nasal cavity temperature detection device stable.

[0035] In addition, the connection between the connecting component 7 and the housing 6 can be connected by a rotating shaft, and a tension spring can be set between the two connecting components 7 to pull the connecting components 7 on both sides toward the middle. Of course, each connecting component 7 can also be provided with a tension spring separately to make the connecting components 7 on both sides converge toward the middle. Only when the connecting components 7 on both sides cooperate with each other and clamp the cow's nose from the middle can the cow's nasal cavity temperature detection device remain stable at the front end. Even if the cow's head shakes, the detection module 5 at the front end will maintain a stable working position without displacement deviation.

[0036] Furthermore, the housing 6 can be divided into two sections, the part where the two connecting components 7 are installed is the front section, and the other part is the rear section. The front section and the rear section can also be connected in a hinged manner, such as Figure 2At A shown in the figure, the front section can be rotated up and down relative to the rear section structure within a certain range. The function is that when the bull's head moves, the front section can be deformed with the movement of the bull's head, thereby ensuring that the overall structure of the bull's nasal cavity temperature detection device will not fall off easily and fit the structure of the bull's head better.

[0037] In one embodiment of the present invention, a microcontroller capable of regulating the working state of the circuit module 1 is provided on the circuit module 1 .

[0038] The function of the microcontroller is to help the circuit module 11 further control the signal transmission and the control functions of power output and access. More control programs and intelligent algorithms can be burned into the microcontroller. The data can be roughly analyzed at the first time when the detection module 5 transmits the detection signal, and then the analyzed data can be sent to the background data center. A certain amount of data model can also be entered. When the detection module 5 detects abnormal data, the cow nasal temperature detection device will first alarm, and then transmit it to the background data center for more detailed data analysis, thereby improving work efficiency.

[0039] In one embodiment of the present invention, a charging interface 9 is provided on the microcontroller 83 .

[0040] The function of the charging interface 9 is to help the microcontroller 83 charge the power module 4. The charging interface 9 can be set to a multi-interface structure suitable for different charging connectors.

[0041] In one embodiment of the present invention, the connecting component 7 includes a hollow tube, a filling layer disposed in the hollow tube, and a power line connecting the circuit module 1 and the detection module 5 wrapped by the filling layer.

[0042] A filling layer is arranged in the hollow tube, and the filling layer can fill the gap between the hollow tube and the power cord, and wrap the power cord in the middle. If water seeps from the outside, the filling layer can play a good role in isolation and waterproofing.

[0043] In one embodiment of the present invention, the filling layer is made of a flexible waterproof material.

[0044] The filling layer of flexible waterproof material can adapt to various spatial structures, allowing itself to deform, and it is easier to cooperate with the special bending shape of the hollow tube to achieve complete sealing and wrapping of the power cord, filling the gaps between the power cords.

[0045] In one embodiment of the present invention, the detection module 5 is externally wrapped with a waterproof terminal 10 .

[0046] The detection module 5 is used to be placed at the front end of the cow's nose. Since a large amount of water vapor is generated by breathing and exhaust, and condenses on the temperature sensor, the detection module 5 must be waterproof. The waterproof terminal 10 is provided to well wrap the overall structure of the detection module 5, and the condensed water vapor will not directly contact the internal circuit of the detection module 5, so the detection module 5 can be well protected and prevented from corrosion caused by water vapor. A transparent cover is provided on the side of the waterproof terminal 10 facing the cow's nasal cavity, so that the internal infrared temperature sensor can directly measure the temperature inside the cow's nasal cavity through the transparent cover.

[0047] In one embodiment of the present invention, the base has straps on both sides. Specifically, strap holes 11 are formed on both sides of the shell 6 in the length direction, and straps are installed in the strap holes 11.

[0048] A strap hole 11 is arranged around the outer shell 6, and a strap is installed on the strap hole 11. The cow nasal cavity temperature detection device is completely tied to the front end of the cow's head through the binding mode, and the cow nasal cavity temperature detection device can be well fixed by using the bridle tethering method.

[0049] like Figure 3 As shown, in one embodiment of the present invention, a tooth-shaped protrusion is provided on the inner periphery of the strap hole 11 .

[0050] The tooth-like protrusions arranged on the inner circumference of the strap hole 11 can increase the friction or locking force of the strap therein, preventing the strap from slipping in the strap hole 11, thereby ensuring that the device will not deviate or fall off after being tied, ensuring the normal use of the device and the accuracy of the collected data.

[0051] like Figure 3 As shown, in one embodiment of the present invention, a toothed clip elastically engaged with the toothed protrusion is further provided in the strap hole 11 .

[0052] The toothed clip is installed in the strap hole 11, and a tension spring is arranged between the toothed clip and the frame around the strap hole 11, so that the toothed clip applies pressure toward the toothed protrusion in the strap hole 11. The tooth gap of the toothed clip matches the tooth gap of the toothed protrusion, clamping the strap in the middle position from both sides, so that the strap with adjusted length can be further tightened by the toothed protrusion and the toothed clip, making it less likely to fall off, and the locking effect is better. After the strap is tied and adjusted, the toothed clip meshes with the toothed protrusion again, further clamping the strap so that it cannot slide freely, thereby increasing the stability of the strap.

[0053] The utility model provides a cow nasal cavity temperature detection device, which uses an infrared temperature sensor to monitor the cow's nasal cavity temperature, and extends into the nasal cavity in the form of a probe. The probe does not contact the inner wall of the nasal cavity, but is suspended in the nasal cavity to achieve automatic temperature detection, and can monitor the cow's body temperature in real time and continuously. It not only achieves automatic temperature detection, but also solves the defects of traditional infrared measurement of cow's body temperature, and has the advantages of real-time, continuous and batch monitoring of cow's body temperature.

[0054] Although the utility model and its advantages have been described in detail, it should be understood that various changes, substitutions and conversions can be made without exceeding the spirit and scope of the utility model defined by the attached claims.
