Description

Technical Field

[0001] This application relates to the field of intelligent transportation systems, and particularly to a high-security road toll payment machine that does not require a person or a card. Background Art

[0002] In today's transportation system, traffic congestion and low payment efficiency have become core issues that urgently need to be solved, and the limitations of existing payment methods have further exacerbated this dilemma. The traditional manual cash payment method not only has extremely low efficiency, resulting in long queues of vehicles waiting, but also has many disadvantages such as inconvenient change, the risk of counterfeit money, and high labor costs. Even the subsequent ETC system also has a series of problems. On the one hand, the installation and use of ETC devices have certain thresholds, and some vehicle owners are deterred due to equipment costs, installation complexity, or concerns about system compatibility, affecting its large-scale popularization; on the other hand, in areas with poor network signals, ETC transactions may be delayed or even fail, unable to ensure the smooth and rapid passage of vehicles. Looking at the mobile payment method, although it has improved the convenience of payment to a certain extent, it highly depends on mobile devices such as mobile phones and a stable network connection. During peak hours or in sections with weak network coverage, mobile payment may also experience problems such as freezing and payment failure. Moreover, in some special cases, such as when the mobile phone battery is insufficient, lost, or damaged, vehicle owners cannot complete the payment smoothly. In addition, from a security perspective, mobile payment involves the transmission and sharing of user account information, there is a certain risk of information leakage, and once the account security is threatened, it may cause greater economic losses to users. The application of biometric technology in the transportation field is still in its infancy, and there is no mature cardless payment machine that integrates palmprint and palm vein recognition on the market. The existing biometric applications mostly focus on single-modal recognition, are easily affected by environmental factors, individual differences, etc., and the recognition accuracy and stability are limited, making it difficult to meet the multiple requirements of high precision, high efficiency, and high security in traffic payment. The market gap in this regard urgently needs to be filled.

[0003] The cardless road toll machine integrating palmprint and palmar vein of the palm developed in this project is an innovative solution proposed in view of the deficiencies of the above-mentioned existing technologies. This toll machine integrates a license plate recognition device, a palmprint recognition device, and a barrier device, realizing the organic integration and coordinated operation of a variety of advanced technologies. Through its unique column structure design, the combination of the ball head at the top of the column and the camera, and the rotational connection between the bottom mounting groove and the ball head, the license plate recognition device enables the camera to flexibly adjust the angle, accurately capture the vehicle license plate information, and quickly analyze and process it with the help of a processing chip, and clearly display the result on the display screen on the side of the column, laying a foundation for subsequent vehicle identity recognition and toll payment operations. The palmprint recognition device, with the ingenious cooperation of the vertical telescopic structure and the horizontal telescopic structure, can flexibly adjust the position of the recognition module to adapt to the palm positions of drivers or passengers with different heights and sitting postures, ensuring the accuracy and convenience of palmprint and palmar vein recognition. Components such as the visible light camera, flash, infrared camera, and distance sensor inside the recognition module work together to collect high-quality palmprint and palmar vein images, and the design of the dust-proof cover plate and light-shielding coating further guarantees the reliable operation of the recognition module and the image acquisition quality. The fixed holes arranged in an array on the mounting plate provide a flexible installation method, facilitating rapid deployment and adjustment according to the requirements of different scenarios. After receiving the instruction from the processing chip, the barrier in the barrier device can quickly control the lifting action of the roadblock bar, realizing effective control of vehicle passage. These series of innovative designs and structural layouts have enabled this toll machine to achieve remarkable breakthroughs and improvements compared with the existing technologies in terms of functional integrity, recognition accuracy, operation convenience, and adaptability.

[0042] like Figures 1-7 A cardless road toll payment machine that integrates palm print and palm vein, comprising: a license plate recognition device 1, a palm print recognition device 2 and a gate device 3, wherein the license plate recognition device 1 comprises a column 11, a ball head 12 is provided on the top of the column 11, a camera 13 is installed on the ball head 12, and a display screen 14 is installed on the side of the column 11;

[0043] The palmprint recognition device 2 includes a vertical telescopic structure 21 and a horizontal telescopic structure 22. An identification module 23 is installed at the end of the horizontal telescopic structure 22. A mounting plate 24 is provided at the bottom of the vertical telescopic structure 21. An array of fixing holes 25 are provided on the mounting plate 24.

[0044] The barrier device 3 comprises a barrier machine 31 , on which a vehicle blocking rod 32 is mounted.

[0045] By setting up license plate recognition equipment, palm print recognition equipment and gate equipment, the automatic, intelligent and cardless payment of vehicle traffic is realized. The license plate recognition equipment can quickly identify the identity of the vehicle, the palm print recognition equipment provides biometric recognition function to enhance security, and the gate equipment controls the passage of vehicles based on the recognition results. This comprehensive design improves the efficiency of traffic payment and reduces manual intervention. It is suitable for intelligent traffic management systems, especially during peak hours, which can effectively alleviate traffic congestion.

[0046] As an improvement, a mounting groove 131 is provided at the bottom of the camera 13, and a rotation connection is adopted between the mounting groove 131 and the ball head 12 for manually adjusting the direction of the camera.

[0047] As an improvement, the camera 13 is connected to a processing chip, and the processing chip is connected to the display screen 14 .

[0048] By setting an installation groove at the bottom of the camera and adopting a rotational connection, the manual adjustment of the camera direction is achieved. This enables the camera to flexibly adjust the angle according to different environments and vehicle positions, improving the accuracy and adaptability of license plate recognition. In complex road conditions or when the vehicle queue is not neat, this design ensures the accurate acquisition of license plate information, thereby enhancing the reliability and efficiency of the entire payment system.

[0049] By connecting the camera to the processing chip and the processing chip to the display screen, the rapid processing and real-time display of license plate information are realized. The processing chip can quickly analyze the images captured by the camera, identify key information such as the license plate number, and immediately present the results on the display screen. This not only improves the speed of information processing but also enables drivers and managers to obtain vehicle information in a timely manner, enhancing the transparency and user experience of the system.

[0050] As an improvement, a vertical telescopic structure 21 is fixedly connected to the mounting plate 24. The vertical telescopic structure 21 includes a vertical cylinder 211 and a lifting rod 212. The lifting rod 212 is L-shaped. One end of the lifting rod 212 away from the cylinder is a square cavity, and a telescopic rod 221 is provided inside the cavity. An identification module 23 is provided at the end of the telescopic rod 221.

[0051] Through the cooperation of the vertical telescopic structure and the horizontal telescopic structure, the flexible positioning of the identification module is achieved. The design of the vertical cylinder and the lifting rod allows the identification module to adjust the height in the vertical direction, while the telescopic rod extends in the horizontal direction. This flexible telescopic mechanism can adapt to drivers or passengers of different heights and sitting postures, ensuring the accuracy and convenience of palmprint and palmar vein recognition. In practical applications, this design improves the success rate of biometric identification, reduces the complexity of user operations, and enhances the applicability and user experience of the device.

[0052] As an improvement, the identification module 23 includes a housing 231. Inside the housing 231, a visible light camera 232, a flash 233, and an infrared camera 234 are installed. A distance sensor 235 is provided on the top of the visible light camera 232. A dust-proof cover plate 236 is provided on one side of the housing 231 away from the telescopic rod 221. A light-shielding coating is provided on the inner side of the dust-proof cover plate 236, and blanks are left at the positions of the visible light camera 232, the flash 233, and the infrared camera 234.

[0053] By integrating a visible light camera, a flash, an infrared camera, and a distance sensor in the recognition module, and setting a dust-proof cover plate and a light-shielding coating, high-quality palmprint and palm vein image acquisition is achieved. The visible light camera and the flash are used for palmprint recognition, the infrared camera is used for palm vein recognition, and the distance sensor ensures the optimal recognition distance. The dust-proof cover plate and the light-shielding coating protect the optical components and prevent dust and external light interference. This comprehensive design improves the accuracy and stability of biometric recognition, is applicable to various environmental conditions, and enhances the reliability and security of the system.

[0054] As an improvement, speakers 26 are provided on both sides of the mounting plate 24, and the speakers 26 are connected to the processing chip through data lines.

[0055] By providing speakers on both sides of the mounting plate and connecting them to the processing chip, the voice prompt function during the payment process is realized. When the verification fails or other situations that need to be reminded occur, the speakers can promptly emit a prompt sound to inform the driver that the payment has failed or that re-operation is required. This not only improves the interactivity and user experience of the system, but also reduces the driver's confusion and operation errors, ensuring the smooth progress of the payment process.

[0056] As an improvement, the cavities of the vertical cylinder 211 and the lifting rod 212 are both connected to an air pump 28 through a hose 27. The air pump 28 is provided on one side of the lifting rod 212, and a solenoid valve is provided at the connection between the air pump 28 and the hose 27.

[0057] By connecting the cavities of the vertical cylinder and the lifting rod to the air pump and setting a solenoid valve, precise control of the telescopic movement of the recognition module is achieved. The air pump provides power, the hose transmits gas, and the solenoid valve controls the on-off of the gas, ensuring the accuracy and timeliness of the telescopic movement. This design improves the response speed and reliability of the device, extends the service life of the device, and reduces the maintenance cost.

[0058] As an improvement, its working method is as follows:

[0059] S1. The vehicle enters the recognition area: When the vehicle drives into the recognition range of the payment machine, the license plate recognition device starts to work;

[0060] S2. License plate information recognition: The processing chip connected to the camera analyzes and processes the captured license plate image, recognizes key information such as the license plate number, and displays the result on the display screen on the side of the column;

[0061] S3. License plate data comparison: Compare the license plate number to determine whether the vehicle is driving in or out. If it is driving in, record the license plate; if it is driving out, retrieve the driving-in record for comparison to determine the deduction information;

[0062] S4. The palmprint recognition device is activated: When the license plate is determined to be driving out, the vertical telescopic structure and the horizontal telescopic structure cooperate to move the recognition module to a suitable position;

[0063] S5, Information Processing and Verification: The collected palmprint and palm vein image data are transmitted to the processing chip. The processing chip uses corresponding biometric algorithms to extract, compare, and verify the palmprint and palm vein features, determine the authenticity of the identity, and associate the verification result with the vehicle information to judge the payment authority and account information of the vehicle.

[0064] S6, Deduction: After double recognition of the palmprint and palm vein, find the user's payment account, deduct the corresponding toll from the corresponding account, display the deduction information on the display screen and announce it through the speaker.

[0065] S7, Barrier Gate Equipment Action: The processing chip sends a signal to the barrier gate equipment, and the blocking rod on the gate rises to allow the vehicle to pass.

[0066] S8, Vehicle Departure and System Reset: After the vehicle passes smoothly, the barrier gate equipment automatically resets within the set time, the blocking rod drops, and prepares to welcome the next vehicle to pass. The telescopic structure of the palmprint recognition device also returns to the initial position, waiting for the next use instruction, and the entire toll collection machine system enters the next working cycle.

[0067] By defining a detailed working method, from the vehicle entering the recognition area to the system reset, the automation and intelligence of the entire payment process are realized. Each step is closely connected, ensuring the efficient execution of vehicle rapid recognition, information processing, fee deduction, and barrier gate control. This complete working process improves the efficiency of traffic payment, reduces vehicle waiting time, and enhances the overall performance and user experience of the system.

[0068] As an improvement, the elongation distance of the horizontal telescopic structure in step S4 is determined according to the preset value of the distance sensor. When the preset value is reached, the processing chip closes the air supply of the air pump.

[0069] By setting the elongation distance of the horizontal telescopic structure to be determined by the preset value of the distance sensor and closing the air supply of the air pump when the preset value is reached, the precise control of the recognition module position is realized. This not only improves the recognition accuracy, but also avoids equipment damage caused by excessive stretching, extends the service life of the equipment, and improves the reliability and stability of the system.

[0070] As an improvement, if the verification fails in step S6, the blocking rod remains in the closed state, and a prompt sound is emitted through the speakers on both sides of the mounting plate to remind the driver that the payment has failed and that they need to re-operate or adopt other payment methods.

[0071] By keeping the barrier closed and emitting a prompt sound when the verification fails, an effective handling of the payment failure situation is achieved. This design reminds the driver to re-operate or adopt other payment methods, ensuring the integrity and accuracy of the payment process, preventing the passage of vehicles without payment, and maintaining the normal operation and revenue security of the toll system.

[0072] Structural design of the license plate recognition device: The license plate recognition device includes a column 11, a ball head 12, a camera 13, and a display screen 14. The camera is located on the ball head, and the ball head is installed at the top of the column. This structural design gives the camera flexible adjustability. In actual traffic scenarios, vehicles come from different directions and have various driving postures. By manually adjusting the ball head, the camera can be accurately aligned with the oncoming vehicle direction to capture the license plate image in all directions. Compared with fixed cameras, it can significantly improve the accuracy of license plate recognition. Especially in complex road conditions or when the vehicle queue is not neat, it can still ensure the effective acquisition of license plate information, providing a reliable basis for subsequent vehicle identity recognition and payment. The display screen on the side of the column presents the license plate information in real time, facilitating the driver and management personnel to view and check in a timely manner, enhancing the transparency and interactivity of the system, and reducing the traffic delay caused by unclear information.

[0073] The telescopic structure and recognition module of the palmprint recognition device: The palmprint recognition device consists of a vertical telescopic structure 21, a horizontal telescopic structure 22, and a recognition module 23. The vertical telescopic structure includes a vertical cylinder 211 and an L-shaped lifting rod 212. The end away from the cylinder is a square cavity with a telescopic rod 221 inside, and the recognition module 23 is installed at the end. In the vehicle payment process, the vertical cylinder drives the lifting rod to expand and contract, driving the recognition module to move up and down, and the horizontal telescopic structure makes the module expand and contract left and right. Such telescopic coordination can adjust the position of the recognition module according to the personnel with different heights and sitting postures to ensure accurate palmprint and palm vein recognition. Compared with fixed recognition devices, it can adapt to more people, improve the success rate and convenience of biometric recognition, and ensure the smooth progress of the payment process. The recognition module is equipped with a visible light camera 232, a flash 233, an infrared camera 234, and a distance sensor 235. The visible light camera and the flash cooperate to collect palmprint images, the infrared camera obtains palm vein images, and the distance sensor monitors the distance between the palm and the module to ensure the quality of image acquisition. The dust-proof cover 236 and the inner light-shielding coating isolate external interference, further improving the image acquisition effect and enhancing the stability and security of biometric recognition. In the field of traffic payment, this comprehensive biometric design utilizes the uniqueness and non-replicability of palmprints and palm veins to greatly improve payment security, effectively prevent risks such as fraud, and provide a more reliable payment method for users.

[0074] Air pump and solenoid valve controlled telescopic system: The cavities of the vertical cylinder 211 and the lifting rod 212 are connected to the air pump 28 through a hose 27, and a solenoid valve is installed at the connection between the air pump and the hose. During the operation of the equipment, the air pump provides power for the telescopic structure, the hose transmits gas, and the solenoid valve precisely controls the on-off of the gas. Compared with other driving methods, the pneumatic system has the advantages of rapid response, stable power, and simple maintenance, which can ensure that the identification module can be quickly and accurately telescoped and positioned, improving the response speed and reliability of the equipment. The setting of the solenoid valve realizes the precise control of the telescopic action, avoids excessive telescoping, extends the service life of the equipment, and at the same time ensures the efficient execution of the biometric identification link, improving the operation efficiency of the entire payment system.

[0075] Association and coordination of each step in the working method: The working method sequentially includes vehicle entering the identification area S1, license plate information identification S2, license plate data comparison S3, palmprint recognition device startup S4, information processing and verification S5, fee deduction S6, gate device action S7, vehicle leaving and system reset S8. Each step is closely connected to form a complete payment process. From the vehicle driving into the recognition range to trigger license plate recognition, to determining the vehicle status based on the license plate and starting corresponding operations, then using dual biometric identification of palmprint and palmar vein to verify identity, complete fee deduction, until the gate is released and the system is reset, this series of steps realizes the automation, intelligence, and cardless of traffic payment. Compared with the traditional payment method, it reduces manual intervention, improves the payment efficiency, and alleviates traffic congestion. In particular, in the fee deduction step S6, the account is deducted in combination with the recognition results of palmprint and palmar vein. The dual biometric identification enhances security, prevents problems such as incorrect fee deduction and card theft, and protects the user's funds. In step S4, the horizontal telescopic structure determines the elongation distance according to the preset value of the distance sensor. When the preset value is reached, the processing chip closes the air supply of the air pump. This detail realizes the precise control of the position of the identification module, ensures that the biometric identification is carried out at the best distance, and improves the identification accuracy and success rate. If the verification fails in step S6, the barrier gate remains closed and is prompted by the speaker, timely reminding the driver to re-operate or use other payment methods, ensuring the integrity of the payment process and the security of the revenue, and maintaining the normal operation order of the toll system.

[0076] In summary, the invention shows unique creativity and remarkable beneficial effects in both structural design and working process, specifically solving the problems of low efficiency, poor security, and insufficient adaptability existing in the existing traffic payment methods, providing an efficient, reliable, and convenient cardless payment solution for intelligent traffic management, and promoting the technological progress and service upgrade in the field of traffic payment.

[0077] Embodiment:

[0078] I. Test preparation and implementation process

[0079] At the main access roads of a large city, five toll stations with relatively large traffic volumes were selected for the experiment, which were respectively marked as test point A, test point B, test point C, test point D, and test point E. At these test points, cardless road toll payment machines integrating palmprint and palmar vein recognition were installed. The payment machine includes a license plate recognition device, a palmprint recognition device, and a barrier gate device.

[0080] The column height of the license plate recognition device is 2.5 meters to ensure that the camera can cover the recognition area for vehicles entering and leaving. The ball head is connected to the camera, and there is an installation groove at the bottom of the camera. The camera direction can be manually adjusted through rotational connection, and the adjustment angle range is ±45 degrees. The camera is connected to a processing chip, and the processing chip is connected to a display screen on the side of the column. The display screen has a size of 24 inches and a resolution of 1920×1080, and can clearly display license plate information.

[0081] The vertical telescopic structure and the horizontal telescopic structure of the palmprint recognition device are both composed of high-precision cylinders and lifting rods and telescopic rods made of high-strength aluminum alloy. The stroke of the vertical cylinder is 0.5 meters, and the telescopic range of the horizontal telescopic rod is 0.3 - 0.8 meters, which can adapt to drivers of different heights and sitting postures. The recognition module is installed at the end of the telescopic rod, and its housing is made of fireproof, dustproof, and waterproof materials. The visible light camera inside has a resolution of 8 million pixels, the flash is a high-brightness LED flash, the infrared camera has a resolution of 5 million pixels, and the measurement accuracy of the distance sensor is ±1 mm. The light-shielding coating on the inner side of the dustproof cover can effectively isolate external light interference.

[0082] The barrier gate of the barrier gate device is made of high-strength steel. The length of the vehicle blocking rod is 4 meters, the rising time is 1.5 seconds, and the falling time is 1.2 seconds, which can quickly respond to the instructions of the processing chip.

[0083] Before the experiment, the drivers around the test points were publicized and trained to make them understand the new payment method and register the payment account information related to palmprint and palmar vein recognition in advance. At the same time, the test equipment was comprehensively debugged and calibrated to ensure the normal operation of all functions.

[0084] During the experiment, when the vehicle drives into the recognition range of the payment machine, the camera of the license plate recognition device automatically starts to capture the vehicle license plate image. The processing chip uses advanced image recognition algorithms to quickly analyze and process the license plate image, identify the license plate number, and display the result on the display screen on the side of the column. The system compares the recognized license plate number with the records in the database to determine whether the vehicle is entering or leaving. For the entering vehicle, the license plate information is recorded; for the leaving vehicle, the entering record is retrieved for comparison to calculate the deduction information.

[0085] When the license plate is determined to have exited, the vertical telescopic structure and the horizontal telescopic structure work together under the control of the processing chip to move the recognition module to a suitable position. The recognition module accurately locates the driver's palm position based on the feedback from the distance sensor. The driver places the palm on the recognition module, and the visible light camera and the flash collect palmprint images, while the infrared camera collects palm vein images. The collected image data is transmitted to the processing chip, and the processing chip uses biometric algorithms to extract, compare, and verify the palmprint and palm vein features to determine the authenticity of the identity. The processing chip associates the verification result with the vehicle information to judge the vehicle's toll payment authority and account information.

[0086] After successful verification, the system deducts the corresponding toll according to the pre-bound payment account. The deducted fee information is displayed on the display screen, and the details of the deducted fee are broadcast through the speakers on both sides of the installation plate. The processing chip sends a signal to the barrier device, and the blocking rod on the barrier quickly rises to allow the vehicle to pass. After the vehicle passes smoothly, the barrier device automatically resets within the set time (30 seconds), the blocking rod drops, and the telescopic structure of the palmprint recognition device also returns to the initial position, waiting for the next vehicle to pass.

[0087] During the entire test process, the vehicle passing data at each test point in different time periods was recorded in detail, including key indicators such as the number of vehicles, license plate recognition time, palmprint and palm vein recognition time, total passing time, recognition accuracy rate, etc. At the same time, a control group was set up, that is, the traditional ETC and manual cash payment methods were continued to be used at adjacent non-test points, and their relevant data was recorded for comparative analysis.

[0092] III. Table Data Analysis

[0093] By comparing the data in Table 1, it can be clearly seen that the cardless road toll payment machine integrating palmprint and palm vein of the present invention has significant advantages and beneficial effects compared with the traditional payment methods.

[0094] In terms of license plate recognition time, the average time at each test point of the present invention is between 0.7 and 0.85 seconds, while the ETC license plate recognition time of the control group is 1.2 seconds. Although the manual cash payment method also has a license plate recognition time of 1.0 second, the overall efficiency is more affected by the subsequent payment link. This is mainly due to the unique structural design of the license plate recognition device of the present invention. The flexible cooperation of the camera with the ball head and the mounting groove can capture the license plate image more accurately. Coupled with the efficient image processing algorithm of the processing chip, the license plate recognition speed has been greatly improved, saving valuable time for the subsequent passing process.

[0095] For palmprint and palm vein recognition time, the average time-consuming for palmprint recognition at the test points is about 1.1 - 1.3 seconds, and the average time-consuming for palm vein recognition is about 1.4 - 1.6 seconds. Although this process increases the recognition steps, the total passing time is significantly shortened from 5.6 seconds of ETC to an average of 4.0 - 4.3 seconds, which is far better than 25.3 seconds of the manual cash payment method. This fully demonstrates the high efficiency brought by the innovative integration of palmprint and palm vein biometric technologies in the present invention. On the one hand, the precise positioning of the vertical telescopic structure and the horizontal telescopic structure enables the recognition module to quickly adapt to the palm positions of different vehicles and personnel. On the other hand, components such as the high-precision visible light camera, flash, infrared camera, and distance sensor inside the recognition module work together to ensure the quality and speed of image acquisition. Combined with advanced biometric algorithms, it can complete the extraction, comparison, and verification of palmprint and palm vein features in an extremely short time, greatly improving the accuracy and speed of identity recognition, thus achieving fast passing.

[0096] In terms of recognition accuracy, the recognition accuracy at the test points is above 99.5%, and the highest can reach 99.8%. The recognition accuracies of ETC and the manual cash payment method in the control group are 98.5% and 97.2% respectively. This shows that the biometric technology of the present invention has higher reliability. Palmprint and palm vein, as unique biometric features of the human body, their uniqueness and non-replicability make identity recognition more accurate, effectively avoiding situations such as fraud and misappropriation that may occur in traditional payment methods. At the same time, the design of the dust-proof cover plate and the light-shielding coating also reduces the influence of external factors on the recognition module, further ensuring the stability of recognition. Even in complex environmental conditions, such as strong light, dust, and vehicle jolts, the present invention can still maintain a high-precision recognition effect, providing a strong guarantee for the safety of traffic payment.

[0097] In addition, the present invention also brings significant improvements in user experience. Compared with ETC equipment that requires car owners to install and maintain electronic tags in advance, and manual cash payment that requires preparing cash and waiting for change, the cardless payment method of the present invention is more convenient and efficient. The driver only needs to perform simple registration and information entry when using it for the first time. When passing through subsequently, he only needs to place his palm on the recognition module to complete the payment process without any additional operation, which greatly reduces the vehicle's stay time at the toll station and alleviates traffic congestion.

[0098] To sum up, through the comparative analysis of actual test data, it can be clearly seen that the palm print and palm vein cardless road pass payment machine of the present invention is superior to the existing ETC and manual cash payment methods in terms of recognition speed, accuracy and user experience, and has significant creativity and novelty. It effectively solves the problems of low efficiency, poor security, inconvenient operation and other problems existing in existing traffic payment methods, and provides a new, efficient and reliable payment solution for the development of intelligent transportation, which has broad application prospects and promotion value.

[0099] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
