Description

Technical Field

[0001] This utility model relates to the field of pig breeding technology, and in particular to a device for measuring the individual performance of breeding pigs. Background Technology

[0002] Performance testing of breeding pigs is a core and fundamental step in breeding pig work. Its core purpose is to provide accurate and reliable quantitative data for genetic evaluation of breeding pigs. As one of the key indicators for evaluating the growth performance of breeding pigs, body weight measurement directly affects the scientificity and accuracy of breeding selection. In the process of body weight measurement, the performance testing device is the core equipment for data collection, and its effectiveness is directly related to the accuracy of the measurement data and the safety of breeding pig feeding.

[0003] Existing performance testing devices for breeding pigs have significant drawbacks in practical applications: due to the active nature of breeding pigs, traditional testing methods require staff to first tie up and fix the breeding pigs before placing them on the weighing device to complete the weighing. However, the tied-up breeding pigs are prone to violent struggles, and their bodies collide and rub against the weighing frame, which can easily lead to injuries to the breeding pigs, affecting subsequent feeding and breeding results. Furthermore, the struggles may cause fluctuations in the weighing data, reducing the accuracy of the test.

[0004] To address the aforementioned issues, Chinese Patent No. CN223500497U discloses a device for testing the performance of breeding pigs. This device includes a weighing platform, a weighing sensor, a weighing frame, a frame door, a support frame, a hydraulic telescopic rod, a movable plate, a movable rod, a connecting block, and a clamping plate. The movable plate, movable rod, and clamping plate are moved by the hydraulic telescopic rod to achieve limited clamping of the breeding pigs, reducing injuries caused by the pigs struggling. At the same time, the support legs and the connecting plate work together to support the hydraulic telescopic rod, improving the structural stability of the device.

[0005] However, the testing device disclosed in this patent still has obvious adaptability defects in practical applications: First, the clamping plate has a single specification and adopts a fixed arc-shaped structure design. When the body size of the breeding pig to be tested is smaller than the diameter of the arc-shaped clamping plate, the clamping plate cannot effectively fit the body of the breeding pig, making it difficult to achieve stable clamping and greatly reducing the limiting effect; Second, there are significant individual differences in the body length of breeding pigs, and the device does not have an adjustment structure for the length direction of the breeding pig. It cannot flexibly adjust the limiting range according to the different body lengths of breeding pigs, resulting in insufficient adaptability of the device and difficulty in meeting diverse testing needs. In summary, the existing breeding pig performance testing device has obvious deficiencies in the flexibility of adapting to breeding pigs of different body sizes, and urgently needs to be improved to enhance its applicability and reliability. Utility Model Content

[0006] To address the aforementioned problems, this invention proposes a device for measuring the individual performance of breeding pigs, in order to more accurately resolve the problems described above.

[0007] This utility model is achieved through the following technical solution:

[0008] This utility model proposes a device for measuring the individual performance of breeding pigs, including a weighing platform. A guardrail is fixedly installed on the top of the weighing platform. Guide rails are fixedly installed on both sides of the top of the guardrail. Adjustment mechanisms are movably installed at both ends of the guide rails. A positioning mechanism is fixedly installed at the lower end of the adjustment mechanism. A guardrail door is hinged to one side of the guardrail.

[0009] The adjustment mechanism includes a slider and limiting holes. The slider is slidably connected to both ends of the guide rail. A connecting frame is fixedly installed on the outer side of the slider. A groove is opened on the top of the connecting frame. A limiting spring is fixedly connected inside the groove. A movable block is fixedly installed on the top of the limiting spring. A limiting plate is fixedly installed on the inner side of the movable block. A limiting pin is fixedly installed on the bottom of the limiting plate. The limiting holes are linearly arranged at equal intervals on the top of the guide rail. The end of the limiting pin is inserted into the limiting hole. The movable block of the adjustment mechanism slides, which can adjust the distance between the two positioning mechanisms according to the different sizes of breeding pigs. This allows the two positioning mechanisms to flexibly adapt to breeding pigs of different body lengths, stably positioning the sides of the breeding pig's body, and providing better overall adaptability.

[0010] Furthermore, a reserved slot is provided in the middle of both sides of the guardrail frame. The end of the positioning mechanism extends through the reserved slot into the interior of the guardrail frame. The reserved slot is used to provide space for the positioning mechanism to move and ensure its stable lateral adjustment.

[0011] Furthermore, an adjusting arm is fixedly installed on the top of the movable block, and an adjusting handle is fixedly connected to the outside of the adjusting arm. When adjustment is required, the adjusting handle can be pulled to drive the adjusting arm to pull the movable block upward, causing the limit spring to stretch. After adjustment, the adjusting arm is released, the limit spring resets, and the limit pin at the bottom of the limit plate can be inserted into the limit hole to complete the locking and limiting.

[0012] Furthermore, limit arms are fixedly installed on the top and bottom of the side of the guardrail gate away from the hinge end. The outer end of the limit arm is threaded with a mounting screw. The end of the mounting screw passes through the limit arm and is threadedly connected to the guardrail frame. The mounting screw is a hand-tightening screw. The mounting screw and the limit arm cooperate to fix the guardrail gate, which facilitates quick opening and closing of the guardrail gate.

[0013] Furthermore, the positioning mechanism includes a fixed sleeve, which is fixedly installed on the lower outer side of the connecting frame. A first electric cylinder is fixedly installed on the inner side of the fixed sleeve, and a clamping module is fixedly installed on the output end of the first electric cylinder. The clamping module moves inside the guardrail frame using the drag force of the first electric cylinder. The clamping module can clamp and fix the body of the breeding pig to ensure that the breeding pig is in a stable state.

[0014] Furthermore, the clamping module includes a clamping seat with an outward V-shaped side. Second electric cylinders are fixedly installed on both the top and bottom sides of the clamping seat. A positioning clamp is fixedly installed through the output end of the second electric cylinder, passing through the clamping seat. The operation of the first electric cylinder can drive the positioning clamp to extend and retract. By adjusting the displacement of the positioning clamp, the size of the inner side of the clamping seat can be further adjusted according to the body shape of different breeding pigs. The outward V-shaped clamping seat's inclined inner surface can stably accommodate breeding pigs of different body sizes.

[0015] Furthermore, a support rod is fixedly installed on the side of the positioning clamp away from the second electric cylinder. The end of the support rod passes through the clamping seat, and the support rod and the clamping seat are slidably connected. The support rod is used to assist in supporting and fixing the positioning clamp to ensure the stability of the positioning clamp.

[0016] The beneficial effects of this utility model are:

[0017] 1. During the application of this technical solution, the guardrail gate control mechanism allows for quick opening and closing of the guardrail gate without the need for additional tools, thereby simplifying the operation process and improving the ease of use of the equipment. This solves the problems of cumbersome opening and closing of guardrail gates and the time and manpower required in the prior art. At the same time, the clamping and fixing mechanism can stably clamp the body of the breeding pig, preventing the breeding pig from struggling violently during the measurement process. This protects the breeding pig from collision injuries and ensures accurate weighing data, solving the problems of easy injury to breeding pigs and large fluctuations in measurement data in the prior art. In addition, this mechanism can adapt to breeding pigs of different body sizes, avoiding the defects of single clamp specifications and poor adaptability in the prior art, further improving the applicability of the equipment.

[0018] 2. During the application of this technical solution, by setting up a multi-dimensional adjustment mechanism, the spacing of the positioning mechanism can be flexibly adjusted according to the body length of the breeding pig during use, thereby achieving the effect of accurately adapting to breeding pigs of different body lengths. This solves the problem of insufficient adaptability and inability to adjust according to the length of the breeding pig in the existing technology. This adjustment function does not require complicated operation; the staff can complete the spacing adjustment with simple operation. This not only improves the adjustment efficiency but also ensures that the positioning mechanism remains stable after adjustment, avoiding the impact of the clamping effect due to the loosening of the mechanism after adjustment. At the same time, in conjunction with the adjustment capability of the clamping mechanism, it forms a comprehensive adaptation to the body size of the breeding pig, solving the problem that the equipment in the existing technology can only adapt to a single body size of breeding pig and has limited applicable scenarios, further enhancing the practicality and versatility of the equipment.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] A device for measuring the individual performance of breeding pigs includes a weighing platform 1, a guardrail 2 fixedly installed on the top of the weighing platform 1, guide rails 5 fixedly installed on both sides of the top of the guardrail 2, an adjustment mechanism 6 movably installed at both ends of the guide rails 5, a positioning mechanism 3 fixedly installed at the lower end of the adjustment mechanism 6, and a guardrail door 4 hinged to one side of the guardrail 2.

[0028] The adjusting mechanism 6 includes a slider 61 and limiting holes 62. The slider 61 is slidably connected to both ends of the guide rail 5. A connecting frame 63 is fixedly installed on the outside of the slider 61. A groove 64 is opened on the top of the connecting frame 63. A limiting spring 65 is fixedly connected inside the groove 64. A movable block 66 is fixedly installed on the top of the limiting spring 65. A limiting plate 67 is fixedly installed on the inside of the movable block 66. A limiting pin 68 is fixedly installed on the bottom of the limiting plate 67. The limiting holes 62 are linearly arranged at equal intervals on the top of the guide rail 5. The end of the limiting pin 68 is inserted into the limiting hole 62. The movable block 66 of the adjusting mechanism 6 slides, which can adjust the distance between the two positioning mechanisms 3 according to the different sizes of the breeding pigs. This allows the two positioning mechanisms 3 to flexibly adapt to breeding pigs of different body lengths, stably positioning the sides of the breeding pig's body. The overall device has better adaptability. During the application of this device, by setting up a weighing platform 1, guardrail 2, guide rail 5, adjusting mechanism 6 and guardrail gate 4, the breeding pig can be first passed through the hinged guardrail gate during use. 4. The pig is driven into the guardrail 2 at the top of the weighing platform 1. Then, the position of the positioning mechanism 3 is adjusted by the adjustment mechanism 6 to adapt to the body shape of the breeding pig. When the adjustment mechanism 6 is running, the operator can operate the movable block 66 to slide. The movable block 66 drives the slider 61 to move inside the guide rail 5. The slider 61 then drives the connecting frame 63 to move synchronously. The connecting frame 63 then drives the positioning mechanism 3 at the lower end to adjust its position. When the spacing of the positioning mechanism 3 is adjusted to adapt to the body length of the breeding pig, the limiting pin 68 at the bottom of the limiting plate 67 will be inserted into the limiting holes 62 arranged at equal intervals at the top of the guide rail 5 to fix the adjustment mechanism 6. Through this adjustment process, the spacing of the two positioning mechanisms 3 can be flexibly adjusted according to the different body sizes of the breeding pigs, so that the two positioning mechanisms 3 can accurately fit the two sides of the body of the breeding pig, making the positioning of the positioning mechanism 3 more stable and avoiding the situation of unstable positioning due to the difference in the body size of the breeding pig. Overall, the device has better adaptability and solves the problem of difficulty in adapting to breeding pigs of different body lengths in the existing technology, improving the stability and applicability of breeding pig performance testing.

[0029] Combination Figures 1-2As shown, reserved slots 7 are provided in the middle of both sides of the guardrail frame 2. The end of the positioning mechanism 3 extends through the reserved slots 7 into the interior of the guardrail frame 2. The reserved slots 7 are used to provide space for the positioning mechanism 3 to move and ensure its stable lateral adjustment. An adjusting arm 69 is fixedly installed on the top of the movable block 66. An adjusting handle is fixedly connected to the outside of the adjusting arm 69. When adjustment is needed, pulling the adjusting handle can drive the adjusting arm 69 to pull the movable block 66 upward, causing the limit spring 65 to stretch and adjust. After completion, release the adjusting arm 69, and the limit spring 65 will reset, which will drive the limit pin 68 at the bottom of the limit plate 67 to insert into the limit hole 62 to complete the locking and limiting. Limit arms 8 are fixedly installed on the top and bottom of the side of the guardrail gate 4 away from the hinge end. The outer end of the limit arm 8 is threaded with a mounting screw 9. The end of the mounting screw 9 passes through the limit arm 8 and is threadedly connected to the guardrail frame 2. The mounting screw 9 is set as a hand-tightening screw. The mounting screw 9 and the limit arm 8 are used to fix the guardrail gate 4, so as to facilitate quick opening and closing of the guardrail gate 4.

[0030] In the above-described embodiments of this application, the device, through the provision of a reserved slot 7, adjusting arm 69, adjusting handrail, limiting arm 8, and mounting screw 9, can better coordinate with the positioning mechanism 3 for adjustment and the opening and closing of the guardrail gate 4 during use. When the position of the positioning mechanism 3 needs to be adjusted, the operator can pull the adjusting handrail, which drives the adjusting arm 69 to pull the movable block 66 upward, causing the limiting spring 65 to stretch. At this time, the limiting pin 68 at the bottom of the limiting plate 67 disengages from the limiting hole 62, thus pushing the positioning mechanism 3 to move. During the movement of the positioning mechanism 3, its end passes through the reserved slot 7 in the middle of both sides of the guardrail frame 2. The reserved slot 7 provides space for the positioning mechanism 3 to move, ensuring the stable horizontal adjustment of the positioning mechanism 3. After the section is completed, the adjusting arm 69 is released, the limiting spring 65 returns to its original position, and the limiting pin 68 at the bottom of the limiting plate 67 is inserted into the limiting hole 62 to complete the locking and limiting. When it is necessary to open or close the guardrail gate 4, since the top and bottom of the side of the guardrail gate 4 away from the hinge end are provided with limiting arms 8, the outer end of the limiting arm 8 is threaded with a hand-tightening installation screw 9. The operator can directly rotate the installation screw 9 so that the end of the installation screw 9 passes through the limiting arm 8 and is threadedly connected or separated from the guardrail frame 2. The installation screw 9 and the limiting arm 8 work together to fix and unlock the guardrail gate 4, which facilitates quick opening and closing of the guardrail gate 4 without the need for additional tools, thus improving the efficiency of operation. At the same time, the setting of the reserved slot 7 also avoids jamming when adjusting the positioning mechanism 3, further ensuring the smoothness of the adjustment process.

[0031] Example 2

[0032] Combination Figures 1-5As shown, the positioning mechanism 3 includes a fixed sleeve 31, which is fixedly installed on the lower outer side of the connecting frame 63. A first electric cylinder 32 is fixedly installed on the inner side of the fixed sleeve 31. A clamping module 33 is fixedly installed on the output end of the first electric cylinder 32. The clamping module 33 moves inside the guardrail 2 using the drag force of the first electric cylinder 32. The clamping module 33 can clamp and fix the body of the breeding pig to ensure that the breeding pig is in a stable state. The clamping module 33 includes a clamping seat 331, which has an outward V-shaped side. A second electric cylinder 332 is fixedly installed on both the top and bottom sides of the clamping seat 331. The output end of the second electric cylinder 332 passes through the clamping seat. A positioning clamp 333 is fixedly installed on the seat 331. The operation of the first electric cylinder 32 can drive the positioning clamp 333 to extend and retract. By adjusting the displacement of the positioning clamp 333, the size of the inner side of the clamping seat 331 can be further adjusted according to the body shape of different breeding pigs. The clamping seat 331 is set in an outward V-shape, and its inner inclined surface can stably adapt to breeding pigs of different body sizes. A support rod 334 is fixedly installed on the side of the positioning clamp 333 away from the second electric cylinder 332. The end of the support rod 334 passes through the clamping seat 331, and the support rod 334 and the clamping seat 331 are slidably connected. The support rod 334 is used to assist in supporting and fixing the positioning clamp 333 to ensure the stability of the positioning clamp 333.

[0033] The technical solution described in the above-described embodiments of this application, during the application of this device, is achieved by setting a positioning mechanism 3 including a fixed sleeve 31, a first electric cylinder 32, a clamping module 33, and a clamping seat 331, a second electric cylinder 332, a positioning clamping plate 333, and a support rod 334, so that the boar body can be stably clamped and fixed during use. When it is necessary to clamp the boar, the first electric cylinder 32 inside the fixed sleeve 31 operates, using its own drag force to drive the clamping module 33 at its output end to move inside the guardrail 2 until the clamping module 33 moves to the position corresponding to the boar body; then the second electric cylinders 332 on the top and bottom sides of the clamping seat 331 operate, and their output ends pass through the clamping seat 331 to drive the positioning clamping plate 333 to extend and retract. By adjusting the positioning... The displacement of the positioning clamp 333 can be further adjusted according to the body shape of different breeding pigs to further adjust the size of the inner side of the clamping seat 331. The side of the clamping seat 331 is set in an outward V-shape, and its inner sloping surface can stably adapt to breeding pigs of different body sizes, ensuring that the clamping seat 331 fits snugly with the body of the breeding pig. At the same time, the end of the support rod 334 on the side of the positioning clamp 333 away from the second electric cylinder 332 passes through the clamping seat 331 and is slidably connected to the clamping seat 331. The support rod 334 can help support and fix the positioning clamp 333, preventing the positioning clamp 333 from shaking during the clamping process and ensuring the stability of the positioning clamp 333. Finally, through this process, the clamping module 33 can reliably clamp and fix the body of the breeding pig, keeping the breeding pig in a stable state and meeting the needs of subsequent performance testing.

[0034] The working principle and advantages of this utility model are as follows: First, the staff needs to open the guardrail door 4 and put the breeding pig into the device. By rotating the hand-tightening installation screw 9 at the outer end of the limiting arm 8, the end of the installation screw 9 is disengaged from the guardrail frame 2, thereby releasing the fixation of the limiting arm 8 to the guardrail door 4. Then, the guardrail door 4 is rotated around the hinge end of the guardrail door 4 to open the entrance of the guardrail frame 2, and the breeding pig to be tested is driven into the guardrail frame 2 at the top of the weighing platform 1. After the breeding pig enters, the guardrail door 4 is rotated in the opposite direction to the closed state, so that the guardrail door 4 fits against the guardrail frame 2. The installation screw 9 is rotated again so that the end of the installation screw 9 passes through the limiting arm 8 and is threadedly connected to the guardrail frame 2. The guardrail door 4 is fixed by the cooperation of the limiting arm 8 and the installation screw 9, preventing the breeding pig from falling out of the guardrail frame 2 during the testing process.

[0035] Next, the distance between the two positioning mechanisms 3 is adjusted according to the body length of the breeding pig. When the worker holds the adjustment handle and pulls it upward, it will cause the adjustment arm 69 to move upward, which in turn will cause the movable block 66 to move upward inside the groove 64 of the connecting frame 63. The movement of the movable block 66 will compress the limiting spring 65 inside the groove 64, and at the same time, it will cause the limiting plate 67 and the limiting pin 68 to move upward, so that the end of the limiting pin 68 disengages from the limiting hole 62 at the top of the guide rail 5. At this time, pushing the connecting frame 63 will cause the bottom slider 61 to slide inside the guide rail 5. The movement of the slider 61 will synchronously drive the positioning mechanism 3 to move. The fence 2 has reserved slots 7 in the middle of both sides. The end of the positioning mechanism 3 can extend into the inside of the fence 2 through the reserved slots 7. The reserved slots 7 provide sufficient space for the lateral movement of the positioning mechanism 3 to ensure the stable movement of the positioning mechanism 3. When the positioning mechanisms 3 on both sides move to the position that matches the length of the boar's body, the adjustment handle is released, the limit spring 65 resets and pushes the movable block 66 down. The movable block 66 drives the limit plate 67 and the limit pin 68 down, so that the end of the limit pin 68 is inserted into the limit hole 62 at the corresponding position, completing the locking and limiting of the adjustment mechanism 6 and fixing the distance between the positioning mechanisms 3 on both sides.

[0036] Subsequently, the first electric cylinder 32 in the positioning mechanism 3 is activated. When the first electric cylinder 32 operates, it pushes or pulls the clamping seat 331, causing the clamping module 33 to move entirely within the guardrail frame 2. When the clamping seat 331 moves to a position close to the boar's body, the first electric cylinder 32 stops operating. Next, the second electric cylinder 332 in the clamping module 33 is activated. The operation of the second electric cylinder 332 pushes or pulls the positioning clamping plate 333, changing the space inside the clamping seat 331 by adjusting the displacement of the positioning clamping plate 333. The side of the clamping seat 331 then faces outwards. The V-shaped design allows its inner sloping surface to fit snugly against the pig's body. Combined with the displacement of the positioning clamp 333, even if the pig's body is small, the positioning clamp 333 can maintain close contact with it. Simultaneously, the support rod 334 slides synchronously with the positioning clamp 333, providing auxiliary support and preventing wobbling during clamping. Once the positioning clamp 333 has secured the pig's body, the second electric cylinder 332 stops operating, and the pig remains stable, ready for weight measurement.

[0037] Furthermore, this device, by incorporating a hand-tightening installation screw 9 in conjunction with a limiting arm 8, eliminates the need for additional tools in opening and closing the guardrail gate 4, significantly reducing operation time. The integration of an adjusting handle, adjusting arm 69, movable block 66, limiting spring 65, limiting pin 68, guide rail 5, and slider 61 allows the spacing of the positioning mechanism 3 to be flexibly adjusted according to the body length of the breeding pig, solving the problem of existing devices being unable to adapt to breeding pigs of different body lengths. The combination of a first electric cylinder 32, a second electric cylinder 332, an outward-facing V-shaped clamping seat 331, a positioning clamping plate 333, and a support rod 334 allows the clamping module 33 to adapt to different body sizes. Smaller breeding pigs are stably clamped, reducing the probability of collisions between the breeding pigs and the guardrail 2, avoiding injury to the breeding pigs, and preventing fluctuations in weighing data due to the struggling of the breeding pigs, thus ensuring measurement accuracy. The fixing sleeve 31 fixes the first electric cylinder 32, the support rod 334 supports the positioning clamp 333, and the guide rail 5 and the slider 61 ensure the linearity of sliding. Together, they prevent the displacement of the first electric cylinder 32, the force deviation of the positioning clamp 333, and the clamping misalignment of the positioning mechanism 3, thereby improving the overall stability of the device and extending its service life. The synergistic effect of these structures comprehensively solves the defects of existing breeding pig performance testing devices in the background technology and meets the diverse needs of breeding pig performance testing.

[0038] During the application of this device, the springs used are made of 60Si2Mn alloy, which has high weather resistance and can be used for a long time. They maintain their high elasticity even after long-term use and can be used in various environments. The first electric cylinder 32 uses a DTZ300 electric actuator with a rated voltage of 24V DC and a rated thrust of 3000N-5000N. The second electric cylinder 332 uses a DTZ160 electric actuator with a rated voltage of 24V. DC rated thrust 1500N-2500N, both electric cylinders are equipped with E6B2-CWZ6C encoders, enabling flexible adjustment of rotation and stepless speed regulation. RV30 gearbox reducers are installed at both the first electric cylinder 32 and the second electric cylinder 332 to assist in increasing torque and controlling speed reduction. The reducer ratio range is 1:10-1:50. The controller is an STM32F103C8T6 microcontroller, installed in the protective box in the middle of the outer side of the guardrail frame 2. The controller has a 5-inch TFT LCD screen. The power supply is 220V AC input converted to 24V via an AC-DC24V 10A switching power supply. After DC, power is supplied to the controller, the first electric cylinder 32, the second electric cylinder 332, and the encoder respectively. The circuit connection is as follows: the output of the controller is connected to the motor end of the first electric cylinder 32 and the second electric cylinder 332 through the motor drive module of model L298N. The encoder signal end is connected to the input end of the controller. The display screen is connected to the controller through the SPI communication interface, forming a complete control loop. The control principle is that the controller receives the electric cylinder displacement signal fed back by the encoder, calculates it through the internal program, and controls the extension and retraction of the electric cylinder through the drive module. At the same time, the running status is displayed on the display screen.

[0039] During use, depending on specific application requirements, a weighing sensor of model HX711 can be installed on the top of the weighing platform 1 to collect real-time weight data of the breeding pigs and transmit it to the controller. A photoelectric sensor of model E3F-DS30C4 can be installed at the guardrail gate 4 to detect the opening and closing status of the guardrail gate 4 and prevent the electric cylinder from malfunctioning. A pressure sensor of model FSR402 can be installed inside the positioning clamp 333 to detect the clamping force and avoid excessive clamping that could damage the breeding pigs. All these sensors are connected to the controller input terminal through signal cables, enabling automatic operation or manual assistance.

[0040] During the application of this device, the fixed installation of each structure can be selected by bolt installation, welding installation, screw installation or some flexible snap-fit ​​installation. If a detachable design is required, bolt or screw installation can be selected. If a stable installation is required, welding installation can be selected. The specific requirements can be flexibly selected according to the application requirements.

[0041] The scope of protection of this application does not involve improvements to the electronic components of the device or equipment. Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.

[0042] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
