Description

Technical Field

[0001] This utility model relates to the field of automated livestock breeding technology, and in particular to a sheep pen positioning device based on ultra-high frequency identification. Background Technology

[0002] With the development of modern animal husbandry, ultra-high frequency RFID technology has been widely used in the automated management of sheep, especially for the location of sheep in different pens. This location tracking usually requires the installation of data acquisition units (i.e., readers) and antennas at key locations in each pen, such as near the water trough.

[0003] However, sheep pens are located in a livestock farm environment with relatively harsh working conditions, including dust, moisture, animal scratches, and the need for frequent washing. This results in a relatively high failure rate for electronic equipment such as data acquisition units installed on-site, requiring regular maintenance or replacement.

[0004] Currently, most existing positioning devices use traditional bolts or clips to fix the data acquisition unit. While these methods are acceptable for initial deployment, they become particularly inconvenient for subsequent maintenance or quick replacement.

[0005] In aquaculture environments filled with contaminants, operators often struggle to accurately align screw holes or require specialized tools for disassembly. This significantly extends equipment maintenance time and reduces operational efficiency and maintainability. Therefore, achieving rapid, stable installation and convenient disassembly of data acquisition units in harsh environments has become a pressing issue in this field.

[0006] Therefore, this utility model proposes a sheep pen positioning device based on ultra-high frequency identification to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems of traditional data acquisition unit installation and fixing methods and cumbersome and time-consuming disassembly and maintenance processes in harsh breeding environments in existing sheep pen positioning devices, this utility model aims to provide a sheep pen positioning device based on ultra-high frequency identification with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a sheep pen positioning device based on ultra-high frequency identification, comprising: a support mechanism, the support mechanism including a mounting plate; a data acquisition unit detachably mounted on the mounting plate; a directional antenna fixedly connected to the data acquisition unit; and a fixing mounting mechanism for locking the data acquisition unit to the mounting plate.

[0010] Furthermore, the fixed installation mechanism also includes a limiting component, which includes a guide rail shaft and an eccentric locking block disposed inside the guide rail shaft. The fixed shaft slides along the guide rail shaft and, driven by the rotating plate, engages with one side of the eccentric locking block to lock the fixed block, or slides out with the other side of the eccentric locking block to release the fixed block.

[0011] Preferably, the support mechanism further includes a support plate, and a passage box is disposed within the support plate; the device further includes a protective cover and a quick-release maintenance mechanism for detachably locking the protective cover to the passage box.

[0012] Preferably, the quick-release maintenance mechanism includes a sliding rod disposed on the outside of the protective cover, a fixed plate connected to the sliding rod, a latching block retractably connected to the fixed plate, and a second spring for elastically driving the latching block; the passage box is provided with a latching groove that selectively engages with the latching block, and a limiting plate is also provided inside to slide with the sliding rod.

[0013] Preferably, the device further includes a sheep pen and a water trough disposed within the sheep pen, and the support mechanism is fixed to the sheep pen near the water trough.

[0014] Preferably, the directional antenna radiates towards the inside of the sheep pen, so that its effective reading range covers the standing area of ​​the sheep at the front of the water trough, and the directional antenna is embedded inside the mounting plate.

[0015] Preferably, the directional antenna is installed at a height of 45 to 55 centimeters above the ground.

The data acquisition unit 4 is pluggably mounted on the mounting plate 31. A directional antenna 5 is fixedly connected to the data acquisition unit 4. The radiation direction of the directional antenna 5 is towards the inside of the sheep pen 1, so that its effective reading range covers the standing area of ​​the sheep in front of the water trough 2. The directional antenna 5 is embedded in the sheep pen 1. The directional antenna 5 is installed inside the mounting plate 31 at a height of 45 to 55 centimeters from the ground. The device also includes a fixing mechanism 8 for detachably locking the data acquisition unit 4 to the mounting plate 31, and a junction box 6 located inside the support plate 32. A protective cover 7 is used to cover the junction box 6, and a quick-release maintenance mechanism 9 is used to detachably lock the protective cover 7 to the junction box 6. The data acquisition unit 4 is connected to the junction box 6 via a cable. The junction box 6 is used to collect the cable and connect to the back-end management platform. The device also includes a data filtering module electrically connected to the data acquisition unit 4. The data filtering module is used to remove invalid ear tag data that is read repeatedly.

[0037] Reference Figure 1 , Figure 2 and Figure 3The fixing and mounting mechanism 8 is used to lock the data acquisition unit 4 to the mounting plate 31. The fixing and mounting mechanism 8 includes a fixing block 81 set at the bottom of the data acquisition unit 4. The mounting plate 31 is provided with a limit block 82 that can slide up and down. The fixing block 81 is used to abut against the limit block 82 downward when inserted into the mounting plate 31. A spring 85 is provided below the limit block 82. The bottom end of the spring 85 is supported on the inner wall of the mounting plate 31 and is used to push the limit block 82 upward. A rotating plate 83 is set below the limit block 82. When the limiting block 82 moves downward, it abuts against and drives the rotating plate 83 to move. A fixed shaft 84 is pivotally connected to the rotating plate 83. The fixed installation mechanism 8 also includes a limiting component 86, which includes a guide shaft 862 and an eccentric locking block 861 disposed inside the guide shaft 862. The fixed shaft 84 slides along the guide shaft 862 and, driven by the rotating plate 83, engages with one side of the eccentric locking block 861 to lock the fixed block 81, or slides out with the other side of the eccentric locking block 861 to release the fixed block 81.

[0038] Preferably, such as Figure 1 and Figure 2 As shown, the support mechanism 3 also includes a support plate 32, in which a bypass box 6 is provided. The device also includes a protective cover 7, which is used to cover the bypass box 6. The device also includes a quick-release maintenance mechanism 9, which is used to detachably lock the protective cover 7 to the bypass box 6.

[0039] Preferably, refer to Figure 2 and Figure 4 The quick-release maintenance mechanism 9 includes a sliding rod 91 located on the outside of the protective cover 7, a fixed plate 92 fixedly connected to the sliding rod 91, a latch 93 telescopically connected to the fixed plate 92, and a second spring 95 located between the latch 93 and the fixed plate 92. The second spring 95 is used to elastically drive the latch 93. The passage box 6 is provided with a latching groove, and the latch 93 selectively engages with the latching groove. The passage box 6 is provided with a limiting plate 94 inside, and the sliding rod 91 slides in cooperation with the limiting plate 94 when inserted into the passage box 6.

[0040] Preferably, such as Figure 1 As shown, the device also includes a sheep pen 1 and a water trough 2 installed inside the sheep pen 1. A support mechanism 3 is fixed to the sheep pen 1 near the water trough 2. The radiation direction of the directional antenna 5 is towards the inside of the sheep pen 1, so that its effective reading range covers the standing area of ​​the sheep in front of the water trough 2. The directional antenna 5 is embedded in the mounting plate 31 and installed at a height of 45 to 55 centimeters from the ground. The data acquisition unit 4 is connected to the junction box 6 via a cable. The junction box 6 is used to collect the cable and connect to the back-end management platform. The device also includes a data filtering module electrically connected to the data acquisition unit 4. The data filtering module is used to remove invalid ear tag data that is read repeatedly.

[0041] The implementation principle of this application embodiment is as follows: When it is necessary to fix the data acquisition unit 4 to the fixed installation mechanism 8, the two data acquisition units 4 are pushed into the mounting plate 31 on the support mechanism 3, which causes the fixing block 81 at the bottom of the data acquisition unit 4 to press down on the limiting block 82. Due to the pressure, the spring 85 is compressed downward. When the limiting block 82 moves downward, it causes the rotating plate 83 to move downward. When the rotating plate 83 moves downward, it causes the fixing shaft 84 to engage with the eccentric locking block 861 inside the guide rail shaft 862 along one side of the circular groove, thus locking the fixing block 81. The limiting component 86 makes the installation more stable. During disassembly... The two data acquisition units 4 are pushed into the mounting plate 31, causing the fixing block 81 at the bottom of the data acquisition unit 4 to press down on the limiting block 82. Due to the pressure, the spring 85 is compressed downward. When the limiting block 82 moves downward, it causes the rotating plate 83 to move downward. When the rotating plate 83 moves downward, it causes the fixing shaft 84 to slide out along the other side of the eccentric locking block 861 inside the guide shaft 862. At this time, the spring 85 rebounds and causes the limiting block 82 and the fixing block 81 to move upward. When the outside of the limiting block 82 slides out of the inside of the guide shaft 862, the limiting block 82 expands outward, releasing the lock on the fixing block 81 and completing the disassembly.

[0042] When maintenance is required on the access box 6 inside the support plate 32, the operator presses the locking block 93 of the quick-release maintenance mechanism 9 inside the access box 6 with their finger, overcoming the elastic force of the second spring 95 to disengage the locking block 93 from the slot of the access box 6. At this time, the lock between the access box 6 and the protective cover 7 is released, and the operator can remove the protective cover 7. After maintenance, the sliding rod 91 outside the protective cover 7 is aligned with the limiting plate 94 inside the access box 6 and inserted to the right. As the sliding rod 91 slides to the right, the fixing plate 92 on it will drive the locking block 93 to move to the right simultaneously and compress the second spring 95. When the locking block 93 moves to the slot position of the access box 6, under the action of the elastic force stored in the second spring 95, the locking block 93 will automatically pop out and lock into the slot, thus completing the installation. The data acquisition unit 4 is installed near the water trough 2 of the sheep pen 1, and the directional antenna 5 is installed on top of the data acquisition unit 4. The radiation direction is towards the inside of sheep pen 1, so that its effective reading range covers the standing area of ​​sheep in front of the water trough 2. The data acquisition unit 4 of sheep pen 1 is connected to the junction box 6 via cable, and then connected to the back-end management platform through a unified power supply and network line. The UHF reader is equipped with a unique device number, which is bound to the number of sheep pen 1, forming a "device-sheep pen 1" mapping relationship. The back-end management platform is used to receive the ear tag ID and the corresponding device number read from each data acquisition unit 4. According to the "device-sheep pen 1" mapping relationship, the ear tag ID is matched to a specific sheep pen 1 to complete the sheep positioning. The directional antenna 5 is installed at a height of 45 to 55 cm above the ground and is embedded in the mounting plate 31. The transmission power parameters of the data acquisition units 4 of adjacent sheep pens 1 are independently adjustable to optimize signal coverage and avoid mutual interference. It also includes a data filtering module to remove invalid ear tag data that is read repeatedly.
