DETAILED DESCRIPTION

[0028] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] The present embodiment provides a sorting device for batch identification of test paper bags with RFID tags, which is mainly used to solve many problems existing in the actual operation of the existing test paper sorting technology. Although RFID technology has shown great advantages in other fields with its non-contact, fast batch reading and strong anti-interference ability, its application in the education and examination industry is still limited. Most of the existing RFID test paper sorting systems rely on electric push rods or other electric mechanical devices to push the test paper bags, which not only increases the complexity and cost of the system, but also may affect the sorting efficiency due to power failure or mechanical failure. At the same time, the sorting speed is low, and the following technical solutions are provided. The following will be combined with Figure 1-Figure 13 Make a detailed description: Embodiment 1:

[0030] A sorting device for batch identification of test paper bags with RFID tags, comprising a conveying mechanism 1, a first identification mechanism 2, a sorting mechanism 3, a second identification mechanism 4 and a plurality of output slideways 5, realizing an automated sorting process of the test paper bags, wherein: The conveying mechanism 1 is used to convey the packaged test paper bags with RFID tags. The conveying mechanism 1 includes a horizontally arranged carrier frame 11 and a conveyor belt assembly 12 arranged on the carrier frame 11. The conveying mechanism 1 is responsible for conveying the test paper bags with RFID tags in a horizontal direction, wherein the carrier frame 11 provides a stable support platform, and the conveyor belt assembly 12 is responsible for the actual conveying action; The sorting mechanism 3 is arranged at the rear end of the carrier frame 11, and the sorting mechanism 3 includes a vertically arranged device frame 31 and a distribution assembly 32 rotatably mounted on the top of the device frame 31, and the distribution assembly 32 is used to receive the test paper bags conveyed by the conveyor belt assembly 12 and distribute them to the corresponding output slideway 5; Multiple output slideways 5 and the conveying mechanism 1 are distributed in a rotating array with the sorting mechanism 3 as the center, ensuring that the test paper bags can be evenly and efficiently distributed to each slideway; During the conveying process, the first identification mechanism 2 is installed on the top of the carrier 11 to perform initial type identification on the test paper bag on the conveyor belt assembly 12. This step helps to preliminarily determine the destination of the test paper bag. Subsequently, the test paper bag is conveyed to the sorting mechanism 3. The second identification mechanism 4 is set above the distribution assembly 32 to perform secondary identification on the test paper bag and control the action of the distribution assembly 32 according to the identification result to ensure that the test paper bag is accurately distributed to the corresponding output chute 5.

[0031] The operation mode of the present invention significantly improves the efficiency and accuracy of test paper bag processing through automated identification and sorting processes. The use of RFID technology makes the identification process of test paper bags unnecessary for human intervention, reducing the possibility of human error. At the same time, the mechanically linked sorting mechanism 3 avoids the use of electric push rods, reduces the complexity and maintenance cost of the equipment, and improves the stability and reliability of the system. In addition, the rotating array distribution design of the output slide 5 makes the distribution of test paper bags more uniform, optimizes space utilization, and improves the overall sorting efficiency. The present invention not only improves the speed and accuracy of test paper sorting, but also reduces the error rate caused by manual operation, ensuring the fairness of the test. At the same time, automated operation reduces labor costs and improves work efficiency. The combination of precise mechanical design and RFID technology enables the present invention to work stably in various environments and has strong adaptability and reliability.

[0032] In the specific embodiment of the present invention, the design and operation of the conveyor belt assembly 12 are crucial to the accurate conveyance of the test paper bag. For details, please refer to Figure 2 , Figure 6 , Fig. 9 and Fig.12The conveyor belt assembly 12 includes a plurality of transmission rollers 121 which are distributed in an array and rotatably mounted on the carrier frame 11. An integrated transmission belt 122 is sleeved on the plurality of transmission rollers 121. The test paper bag is placed on the top of the transmission belt 122 and is transported forward with the continuous movement of the transmission belt 122. The conveyor belt assembly 12 also includes a servo motor 123 arranged under the carrier frame 11. The servo motor 123 ensures the stability and consistency of the speed of the transmission belt 122 with its precise control ability. A rotating rod 124 is fixed on the output end of the servo motor 123. A driving wheel 125 is fixedly sleeved on the rotating rod 124. A driven wheel 126 is fixedly sleeved on one end of one of the edgemost transmission rollers 121. An integrated transmission belt 127 is sleeved between the driven wheel 126 and the driving wheel 125. Such a design enables the rotational movement of the servo motor 123 to be transmitted to the driven wheel 126 through the transmission belt 127, thereby driving the rotation of the transmission roller 121 to realize the continuous conveying action of the transmission belt 122. This design brings significant beneficial effects. First, the precise control of the servo motor 123 enables the conveyor belt assembly 12 to achieve precise speed control and positioning, which is crucial for subsequent RFID identification and sorting operations. Secondly, the integrated conveyor belt 122 and the array-distributed conveyor rollers 121 provide a stable and continuous conveying path, ensuring the smooth movement of the test paper bag during the conveying process, reducing the misalignment or falling of the test paper bag due to unstable factors during the conveying process. In addition, the driving wheel 125 and the driven wheel 126 cooperate with the transmission belt 127 to simplify the power transmission structure, improve the power transmission efficiency, and reduce maintenance costs and failure rates.

[0033] In the specific embodiment of the present invention, the design and operation of the distribution assembly 32 is crucial to achieve accurate distribution of the test paper bags to the corresponding output chute 5. For further information, please refer to Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 and Fig.11 The distribution assembly 32 includes a support rod 321 vertically rotatably mounted on the top of the device frame 31, a circular receiving plate 322 is fixed on the top of the support rod 321, and the top side of the receiving plate 322 is lower than the top side of the conveyor belt 122 to ensure that the test paper bag can smoothly transition from the conveyor belt 122 to the receiving plate 322, and a circular distribution plate 323 is fixed on the top of the receiving plate 322, and a plurality of evenly distributed receiving grooves 324 are constructed on the outer peripheral side of the distribution plate 323. The number of the receiving grooves 324 is equal to the sum of the conveying mechanism 1 and the plurality of output slideways 5 and is always one-to-one corresponding to ensure that each test paper bag can be accurately guided to the correct output slideway 5; The top of the distribution plate 323 is provided with a plurality of ejection members 33 for pushing the test paper bags into the corresponding output slides 5. The plurality of ejection members 33 are respectively located inside the plurality of receiving slots 324 to achieve the final distribution of the test paper bags. In order to accurately control the rotation of the support rod 321, a control member 34 for accurately controlling the rotation of the support rod 321 is provided on the device frame 31. The function of the control member 34 is to ensure that the distribution plate 323 can accurately guide the test paper bags to the correct receiving slots 324 and finally push them to the correct output slide 5. This design brings about significant beneficial effects. First, by controlling the precise rotation of the support rod 321, the distribution component 32 can ensure that the test paper bags are accurately distributed to the designated output chute 5, greatly improving the accuracy and reliability of the sorting process. Secondly, the one-to-one correspondence between the receiving slot 324 and the output chute 5, as well as the precise control of the ejector 33, ensure that the test paper bags will not be mistakenly distributed to other output chutes 5 even in the case of high-speed sorting. In addition, the design of the distribution component 32 allows for fast and continuous test paper bag distribution, thereby improving the working efficiency of the entire sorting equipment.

[0034] In this embodiment, the design of the control member 34 plays a key role in achieving accurate reception of the test paper bags and distribution to the corresponding output chute 5, see Figure 2 , Figure 6 , Figure 8 , Fig.11 and Fig.12 The control member 34 includes a dividing wheel 341 fixedly sleeved on the support rod 321, and a plurality of evenly distributed dividing grooves 342 are constructed on the outer peripheral side of the dividing wheel 341. The number of dividing grooves 342 is equal to the sum of the conveying mechanism 1 plus a plurality of output slideways 5 and they always correspond one to one, ensuring that each test paper bag can be accurately guided to the correct output slideway 5. The number of dividing grooves 342 is N, which provides a precise control point for the system; A control rod 343 is rotatably mounted on the top of the device frame 31, and a control block 344 is fixed on the top of the control rod 343. An adjustment rod 345 is fixed on the control block 344 and can be movably inserted into each indexing groove 342 in sequence. Whenever the control rod 343 rotates one circle, the adjustment rod 345 is movably inserted into one of the indexing grooves 342 and drives the indexing wheel 341 to rotate 360 / N degrees and correspond to the next adjacent indexing groove 342. This design enables the rotation of the indexing wheel 341 to drive the receiving plate 322 to rotate, ensuring that each time the receiving plate 322 rotates once, the receiving groove 324 can correspond to one of the output slideways 5 or the conveyor belt 122, and the positioning of the test paper bag is accurate and synchronized; A bevel gear 1 346 is fixedly sleeved on the rotating rod 124, a bevel gear 2 347 is fixedly sleeved on the control rod 343, a horizontal transmission rod 348 is rotatably mounted on the device frame 31, and bevel gears 3 349 are fixedly sleeved on both ends of the transmission rod 348. The two bevel gears 349 are respectively meshed with the bevel gear 1 346 and the bevel gear 2 347. The design of the bevel gear 1 346, the bevel gear 2 347 and the bevel gear 3 349 realizes the power transmission and precise control from the servo motor 123 to the indexing wheel 341; A plurality of evenly distributed positioning frame grooves 128 are constructed on the outer peripheral side of the conveyor belt 122. The test paper bag is placed inside the positioning frame grooves 128. The diameter of the driving wheel 125 is much larger than the diameter of the driven wheel 126. Such a design enables the conveyor belt 122 to be precisely controlled when the servo motor 123 drives the rotating rod 124 to rotate. Whenever the servo motor 123 drives the rotating rod 124 to rotate M full circles, the indexing wheel 341 rotates 360 / N*M angles and the test paper bag inside one of the positioning frame grooves 128 enters the inside of one of the receiving grooves 324. It should be noted that, in this embodiment, the number of indexing grooves 342 is set to six, and the six indexing grooves 342 are evenly distributed on the outer peripheral side of the indexing wheel 341, and correspond one to one with the total number of combinations of the conveying mechanism 1 and the output slideway 5. Then, the number of the output slideway 5 is five. Figure 1 To illustrate the front view, the test paper bag is placed in one of the positioning frame grooves 128 on the top side of the conveyor belt 122, and the servo motor 123 drives the rotating rod 124 to rotate one circle. Through the linkage of the driving wheel 125, the transmission belt 127 and the driven wheel 126, the test paper bag is transported to the end of the carrier 11 through the conveyor belt assembly 12 and enters one of the receiving grooves 324 corresponding to the conveyor belt 122. Then the servo motor 123 drives the rotating rod 124 to rotate one circle. Through the linkage of the bevel gear 1 346, the bevel gear 2 347 and the bevel gear 3 349, the control rod 343 is driven to rotate one circle, and the adjustment rod 345 on the top of the control rod 343 rotates one circle, realizing the following process: 1. Entering one of the indexing grooves 342; 2. Drive the indexing wheel 341 to rotate 60 degrees and leave the indexing groove 342; 3. Correspond to the next adjacent indexing groove 342 to prepare for the next rotation; at this time, the receiving groove 324 receiving the test paper bag corresponds to the first output slide 5 beside the conveyor belt 122, and matches to infer whether the test paper bag needs to be pushed out. If not, repeat this process. Every time the rotating rod 124 rotates one circle, a test paper bag inside the positioning frame groove 128 will enter the interior of one of the receiving grooves 324. If the test paper bag cannot be placed in each positioning frame groove 128 continuously, it will not affect the corresponding receiving groove 324. If the test paper bag does not receive the test paper bag, it will realize an idle rotation, and will not cause system disorder; This design brings about significant beneficial effects. First, by accurately controlling the rotation of the dividing wheel 341, a one-to-one correspondence between the test paper bag and the output slide 5 is ensured, greatly improving the accuracy and reliability of the sorting process. Secondly, the introduction of bevel gear 1 346, bevel gear 2 347 and bevel gear 3 349 realizes the power transmission and precise control from the servo motor 123 to the dividing wheel 341, improving the response speed and control accuracy of the entire system. In addition, the design of the positioning frame groove 128 makes the positioning of the test paper bag during the transportation process more accurate, reducing sorting errors caused by inaccurate positioning.

[0035] The design and operation of the ejector 33 are crucial to achieving the rapid and accurate ejection of the test paper bag to the corresponding output chute 5. For details, see Figure 3 , Figure 4 , Figure 5 , Figure 7 and Fig.13 The ejection member 33 includes a mounting groove 331 constructed on the top side of the receiving plate 322, and a plurality of rotating rollers 332 distributed in an array are rotatably mounted between two inner walls opposite to each other in the mounting groove 331. The plurality of rotating rollers 332 are all arranged horizontally and their top sides are lower than the top side of the conveyor belt 122, so as to ensure that the test paper bag can smoothly move from the conveyor belt 122 to the output slideway 5; The bottom side of the receiving plate 322 is configured with two symmetrically arranged device grooves 333, and the two ends of the rotating shaft of the rotating roller 332 respectively penetrate into the two device grooves 333, and a linkage wheel 334 fixedly sleeved on one end of the rotating roller 332 is arranged inside one of the device grooves 333, and a plurality of linkage wheels 334 are sleeved with an integrated linkage belt 335, so that the movement of the rotating roller 332 can be transmitted through the linkage belt 335, thereby realizing a linkage effect; The other end of the rotating shaft of one of the outermost rotating rollers 332 is fixedly sleeved with a friction wheel 336 located inside another device groove 333, and the ejector 33 also includes an auxiliary part 337 for controlling the rapid rotation of the friction wheel 336. This design is to quickly push the test paper bag into the output slideway 5 when necessary; The introduction of the auxiliary part 337 enables the ejection member 33 to not only smoothly move the test paper bag from the conveyor belt 122 to the receiving plate 322, but also to quickly eject the test paper bag through the rapid rotation of the friction wheel 336 at a critical moment. This design improves the response speed and reliability of the ejection action, ensuring that the test paper bag can be accurately pushed to the correct output chute 5 even in the case of high-speed sorting.

[0036] Furthermore, in this embodiment, the detailed structure and operation mode of the auxiliary portion 337 play a decisive role in the rapid push-out of the test paper bag to the corresponding output chute 5. For details, please refer to Figure 3 , Figure 4 , Figure 5 , Figure 7 and Fig.13 The auxiliary part 337 includes an auxiliary frame 3371 installed at the bottom of the receiving plate 322, and an auxiliary wheel 3372 is rotatably installed on the auxiliary frame 3371. The top side of the auxiliary wheel 3372 is in contact with the bottom side of the friction wheel 336 to ensure the power transmission efficiency between the two. A connecting plate 3373 is fixed at the bottom of the receiving plate 322 and at a position corresponding to the auxiliary wheel 3372. A horizontal connecting rod 3374 is movably inserted through the connecting plate 3373. A friction block 3375 located below the auxiliary wheel 3372 is fixed at one end of the connecting rod 3374. The top side of the friction block 3375 is flush with the bottom side of the auxiliary wheel 3372 and does not contact the bottom side of the auxiliary wheel 3372 under normal conditions to avoid unnecessary friction and wear. A stopper 3376 is fixed at the other end of the connecting rod 3374. A spring 3377 sleeved on the connecting rod 3374 is connected between the stopper 3376 and the connecting plate 3373. The function of the spring 3377 is to quickly reset the friction block 3375 after it is released to prepare for the next push-out operation. Specifically, a fixing rod is fixed on the side of the friction block 3375 facing away from the connecting rod 3374, and an iron block 3378 is fixed on the fixing rod. An electromagnet 3379 that can be powered on and off and corresponds to the iron block 3378 is fixed on the output slide 5. An inductor 51 is provided on the output slide 5. When one of the receiving slots 324 with the test paper bag is rotated to be on the same straight line as the corresponding output slide 5, the inductor 51 matches with the second identification mechanism 4. At this time, the electromagnet 3379 is powered on to quickly absorb the iron block 3378. The absorption effect of the electromagnet 3379 causes the friction block 3375 to quickly move through the auxiliary wheel 3372, thereby driving the auxiliary wheel 3372 to rotate. The auxiliary wheel 3372 drives several rotating rollers 332 to rotate quickly through the friction wheel 336, and the test paper bag slides into the corresponding output slide 5. Then the electromagnet 3379 is powered off, and the friction block 3375 is reset under the elastic force of the spring 3377 to prepare for the next push-out operation. This design brings about significant beneficial effects. First, the quick response mechanism of the auxiliary part 337 enables the test paper bag to be quickly and accurately pushed out to the correct output slide 5, greatly improving the sorting efficiency. Secondly, the coordinated use of the electromagnet 3379 and the sensor 51 realizes the precise control of the test paper bag pushing action, ensuring the high accuracy of the sorting process. In addition, the use of the spring 3377 increases the reset speed of the friction block 3375, reduces the non-working time of the pushing member 33, and improves the working efficiency of the entire sorting equipment. The design of the auxiliary part 337 not only improves the efficiency and accuracy of the test paper bag distribution, but also provides a strong guarantee for the performance of the entire test paper sorting equipment through its quick response and precise control mechanism.

[0037] See also Figure 3 The first identification mechanism 2 includes a dark box 21 fixed on the top of the carrier 11. The design of the dark box 21 is to provide protection for the internal components and ensure the effective reception and transmission of RFID signals. A plurality of first RFID detection antennas 22 distributed at multiple angles are installed inside the dark box 21. The design of these first RFID detection antennas 22 takes into account the movement characteristics and spatial distribution of the test paper bag on the conveyor belt assembly 12. Through the multi-angle layout, the omni-directional and no-dead-angle recognition of the RFID tag on the test paper bag is ensured. The first RFID detection antenna 22 can transmit and receive RFID signals and read the RFID tag information attached to the test paper bag, including but not limited to the key information such as the test subject and test site to which the test paper bag belongs; This design brings significant beneficial effects. First, the multi-angle distributed first RFID detection antenna 22 can ensure that no matter where the test paper bag is on the conveyor belt 122, its RFID tag can be accurately read, thereby improving the reliability and accuracy of identification. Secondly, the setting of the dark box 21 provides physical protection for the first RFID detection antenna 22, so that it is protected from the influence of the external environment, such as dust, moisture, etc., thereby ensuring the long-term stable operation of the equipment. In addition, the first identification mechanism 2 is set on the top of the carrier 11, so that the test paper bag can be identified and classified before entering the sorting mechanism 3, providing important data support for the subsequent precise allocation.

[0038] For further information, see Figure 2 and Figure 8 The second identification mechanism 4 includes a shielding plate 41 fixed to the top side of the distribution plate 323. The shielding plate 41 is designed to provide protection for the internal components and ensure the effective reception and transmission of RFID signals to prevent external signal interference. A plurality of second RFID detection antennas 42 are arranged at the bottom of the shielding plate 41. The plurality of second RFID detection antennas 42 correspond to a plurality of receiving slots 324 respectively. Through the one-to-one corresponding layout, accurate identification of the RFID tag on the test paper bag is ensured. Each second RFID detection antenna 42 corresponds to a specific receiving slot 324, so that when the test paper bag is allocated to the receiving slot 324, the RFID tag information attached to the test paper bag can be accurately read, including but not limited to the key information such as the test subject and test site to which the test paper bag belongs; The one-to-one layout of the second RFID detection antenna 42 can ensure that when the test paper bag is allocated to a specific receiving slot 324, its RFID tag information is accurately read, thereby improving the reliability and accuracy of identification. Secondly, the setting of the shielding plate 41 provides physical protection for the second RFID detection antenna 42, so that it is immune to the influence of the external environment, such as electromagnetic interference, thereby ensuring the long-term stable operation of the equipment. In addition, the second identification mechanism 4 is set on the top side of the distribution plate 323, so that the test paper bag can be confirmed for the last time before it is finally pushed to the output slide 5, ensuring the high accuracy of the sorting process. Embodiment 2:

[0039] In the second embodiment of the present invention, the design and construction of the output slideway 5 play an important role in ensuring that the test paper bag slides out smoothly and enters the corresponding position. For details, please refer to Figure 1 , Figure 3 and Figure 7 The top side of the output slide 5 is inclined and the higher end is close to the receiving plate 322, and the higher end of the output slide 5 is lower than the top side of the receiving plate 322. This design helps the test paper bag to slide from the receiving plate 322 into the output slide 5 more smoothly under the action of gravity. The two opposite sides of the output slide 5 are provided with protective plates 52 that are always higher than the top side of the output slide 5 to prevent the test paper bag from deflecting or tipping over during the sliding process. This design brings the following beneficial effects: first, the inclined output chute 5 design enables the test paper bag to slide out naturally with the help of gravity, reducing the additional energy required during the pushing process and improving the efficiency of the sorting process; second, the provision of the protective plate 52 enhances the structural stability of the output chute 5, protecting the test paper bag from deviating from the predetermined trajectory during the sliding process, thereby ensuring the safety and reliability of the sorting process; in addition, by precisely controlling the height difference between the output chute 5 and the receiving plate 322, a smooth transition of the test paper bag is ensured, thereby avoiding damage to the test paper bag or sorting errors caused by improper height. Embodiment three:

[0040] Example 3 is a further optimization of Example 1. Figure 3 and Figure 8 The top of the device frame 31 is also provided with a plurality of evenly distributed bearing members 35 for supporting the receiving plate 322. The bearing members 35 include a bearing rod 351 vertically fixed to the top of the device frame 31. The top side ball of the bearing rod 351 is connected with a plurality of evenly distributed supporting balls 352. The plurality of supporting balls 352 roll on the bottom side of the receiving plate 322. This design enables the receiving plate 322 to move smoothly while maintaining good contact with the device frame 31. The rolling characteristics of the supporting balls 352 help to reduce the friction of the receiving plate 322 during the rotation process, thereby reducing energy consumption and improving the operating efficiency and life of the equipment. This design brings the following beneficial effects: first, the uniform distribution of the support members 35 ensures that the receiving plate 322 is evenly stressed during the entire operation, preventing deformation or damage caused by uneven stress; second, the free rotation and rolling characteristics of the supporting balls 352 reduce mechanical wear and extend the maintenance cycle and service life of the equipment; in addition, the design of the support members 35 also helps to improve the flexibility and response speed of the entire sorting equipment, especially in high-speed sorting operations, ensuring the quick and accurate positioning of the receiving plate 322.

[0041] The following is a detailed description of the sorting process: First, the test paper bag is placed in one of the positioning frame slots 128 on the top side of the conveyor belt 122 and conveyed forward. The servo motor 123 accurately controls the speed and position of the conveyor belt to ensure that the test paper bag moves smoothly along the predetermined path. While the test paper bag is moving, the first RFID detection antenna 22 of the first identification mechanism 2 reads the RFID tag on the test paper bag to obtain its information. The test paper bag enters one of the receiving slots 324 corresponding to the conveyor belt 122, and the corresponding second RFID detection antenna 42 performs re-recognition confirmation to ensure that the information is correct. Then the servo motor 123 drives the rotating rod 124 to rotate. Every time the rotating rod 124 rotates one circle, the driving wheel 125, the driven wheel 126 and the transmission belt 127 are linked to drive the next positioning frame slot 128 where the test paper bag is placed to move to correspond to one of the receiving slots 324, and transport the test paper bag inside the positioning frame slot 128 to the inside of the receiving slot 324. At the same time, the rotating rod 124 drives the control rod 343 to rotate one circle through the bevel gear 1 346, the bevel gear 2 347 and the bevel gear 349. Every time the control rod 343 rotates one circle, the adjusting rod 345 will be inserted into the indexing groove 342 in turn, so that the indexing wheel 341 rotates 360 / N degrees (where N is the total number of indexing grooves 342, which is also the total number of output slideways 5), and the receiving slots 324 where the test paper bags are placed will correspond to a number of output slideways 5 in turn. When the sensor 51 on one of the output slides 5 senses the matching test paper bag, the electromagnet 3379 is energized, and the electromagnet 3379 is energized to quickly absorb the iron block 3378. The absorption effect of the electromagnet 3379 causes the friction block 3375 to quickly move through the auxiliary wheel 3372, thereby driving the auxiliary wheel 3372 to rotate. The auxiliary wheel 3372 drives several rotating rollers 332 to rotate quickly through the friction wheel 336, and slides the test paper bag into the corresponding output slide 5. Then the electromagnet 3379 is de-energized, and the friction block 3375 is reset under the elastic force of the spring 3377 to prepare for the next push-out operation.

[0042] It should be noted that the specific models and specifications of the servo motor 123, the first RFID detection antenna 22, the electromagnet 3379, the second RFID detection antenna 42 and the sensor 51 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail. The principles of these components are clear to those skilled in the art and do not need to be described in detail here.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
