Technical Field

[0001] The present invention relates to the technical field of elevators and their control, and specifically to an elevator with palmprint, palm vein and pupil recognition functions, as well as its control system and control method. Background Art

[0002] Currently, traditional elevator control systems mainly use methods such as button floor selection or card swiping recognition, which have many drawbacks. On the one hand, the button floor selection method cannot effectively restrict the use by unauthorized personnel, posing certain safety hazards. Especially in some places with high security requirements, such as financial institutions and confidential departments, it is difficult to meet their safety needs; card swiping recognition has problems such as easy loss and theft of cards, and the card production cost and management cost are relatively high. On the other hand, traditional elevators also lack in terms of convenience and hygiene. For example, during public health events, contact buttons are prone to becoming a medium for virus transmission. Summary of the Invention

[0003] The present invention aims to provide an elevator with palmprint, palm vein and pupil recognition functions, as well as its control system and control method, to solve the problems of insufficient security, poor convenience and hygiene hazards existing in the existing elevator control methods, so as to achieve safer, more convenient and more hygienic elevator control.

Detailed implementation manners

[0036] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0037] Embodiment 1

[0038] This embodiment discloses an elevator with palmprint, palm vein and pupil recognition functions, including an elevator and a control device. The control device includes an acquisition component 1, a recognition component 2 and a storage component 3.

[0039] The acquisition component 1 includes a palm information acquisition panel 11 and a pupil image acquisition device 12. The palm information acquisition panel 11 integrates a palmprint acquisition device 111 and a palm vein acquisition device 112. The palm information acquisition panel 11 is arranged on one side of the elevator door of the elevator.

[0040] Among them, the palmprint acquisition device 111 includes a first camera 111a for acquiring palmprints, and fill lights 111b are arranged on both sides of the first camera 111a. The palmprint acquisition device 111 obtains a palmprint image through an optical acquisition device, and then transmits the acquired information to the recognition component 2. The recognition component 2 performs pre - processing operations such as grayscale conversion, filtering, and binarization on the acquired image to remove noise and interference and highlight the palmprint features. Then, the acquired information is compared with the pre - entered palmprint information in the storage component 3, and a control instruction is output.

[0041] The palm vein acquisition device 112 includes an infrared emitter 112a and an infrared camera 112b. The infrared emitter 112a emits near-infrared light. When the near-infrared light penetrates the palm, the vein blood vessels will absorb part of the light, causing the blood vessels to appear as dark patterns in the image. The infrared camera 112b captures the differences and forms a palm vein image, and then transports the palm vein image to the recognition component 2. The recognition component 2 performs preprocessing operations such as grayscale conversion, filtering, and binarization on the acquired image to remove noise and interference, and then extracts the features of the vein blood vessel network, such as the structural information of the blood vessel's orientation, bifurcation points, and intersection points, to form a feature template. Then, the acquired information is compared with the pre-entered palm vein information in the storage component 3, and a control instruction is output.

[0042] The pupil image acquisition device 12 includes a fixed base 121, a support rod 122, and a high-definition camera 123. A light shield 124 is provided on the high-definition camera 123. The fixed base 121 is arranged at a position obliquely above one side of the elevator door, and the direction of the high-definition camera 123 faces the area in front of the elevator door. The pupil image acquisition device 12 is arranged obliquely above the elevator door. When a passenger gazes at the pupil image acquisition device 12, the high-definition camera 123 captures the passenger's pupil image, and then performs preprocessing such as grayscale conversion, filtering, and binarization on the acquired image to improve the image quality and enhance the extractability of the features. The texture, shape, size, and other feature information of the pupil are extracted from the preprocessed image, converted into a feature vector or a feature template, and finally, the features of the pupil to be recognized are compared with the features stored in the storage component 3, and a control instruction is output.

[0043] Compared with the horizontal setting of the high-definition camera 123, the oblique design can effectively avoid the problem that it is difficult for the eyes of passengers of different heights to be aligned, thereby reducing the difficulty of pupil image acquisition. A light shield 124 is also provided on the high-definition camera 123 to avoid the influence of external light sources on pupil image acquisition.

[0044] A single recognition method may have the risk of being forged or breached. For example, in some cases of palmprint recognition, the palmprint pattern may be replicated by a high-precision imitation. Although palm vein recognition is relatively difficult to forge, if there are special blood circulation disorders or breakthroughs in forgery techniques, loopholes may also occur. Pupil recognition may also be deceived by highly imitated pupil images with an extremely low probability. Combining these three recognition methods greatly reduces the probability of being illegally breached, forms a multi-verification mechanism, thereby more reliably ensuring the safety of elevator use and effectively preventing unauthorized personnel from entering.

[0045] In addition, misjudgments may occur in certain scenarios with different recognition methods. When there are stains, wounds, or abrasions on the palm, the recognition accuracy of palmprint recognition may decrease; palm vein recognition may have errors in cases such as abnormal hand temperature and blood circulation status; pupil recognition is also subject to certain fluctuations due to factors such as light intensity and shooting angle. By integrating the three recognition methods, they can complement and confirm each other. When an error occurs in one recognition method, the other two can play a corrective role, and by judging based on multiple features, the overall recognition accuracy can be significantly improved, the occurrence of misidentifications can be reduced, and the identity of the legitimate user can be accurately confirmed.

[0046] The control device further includes an induction component 4, and the induction component 4 is an infrared sensor for sensing the human body. Only when the induction component 4 senses the human body, the acquisition component 1 is activated. When there is no one, the acquisition component 1 is in a standby state, which can achieve the purpose of power saving.

[0047] A display screen 5 for displaying the elevator floor is provided at the top of the elevator door.

[0048] This embodiment also discloses an elevator control system with palmprint, palm vein, and pupil recognition functions, including an information acquisition module, an information recognition module, a storage module, and a user management module;

[0049] The information acquisition module is used to acquire the biometric information of the user, including: palmprint information, palm vein information, and pupil information. Among them, the palmprint information is acquired by the palmprint acquisition device 111, the palm vein information is acquired by the palm vein acquisition device 112, and the pupil information is acquired by the pupil image acquisition device 12. The information acquisition module uses multi-modal recognition technology to integrate multiple biometric features such as palmprint, palm vein, and pupil for recognition. Compared with single recognition methods, it greatly improves the recognition accuracy and security, and effectively reduces the false recognition rate and rejection rate. In addition, the acquisition processes of palm vein and pupil information do not require the user to contact the device, avoiding hygiene problems and cross-infection risks caused by contact, being more convenient and hygienic, and having a high user acceptance. Palm vein recognition is less affected by external environmental factors such as light changes and palm surface stains, and pupil recognition also has strong environmental adaptability, ensuring the stability and reliability of information acquisition under different conditions.

[0050] The storage module is used to store pre - entered palmprint information, palmar vein information, and eye pupil information; the storage module adopts a distributed storage architecture, stores the user's biometric information in multiple independent storage units respectively, and performs data synchronization and interaction through an encrypted communication link to improve the reliability of the storage system and the security of data. The distributed storage architecture avoids the risk of single - point failure. Even if a certain storage unit fails, it will not cause the loss of the entire system data or the inability to operate normally, improving the availability and reliability of the system and ensuring the continuous and stable operation of the elevator control system. The stored data is encrypted and transmitted through an encrypted communication link to prevent the data from being stolen, tampered with, or leaked during storage and transmission, effectively protecting the privacy and biometric information of users and reducing security risks. In addition, the distributed storage architecture is convenient for flexibly adding storage units according to the increase in the number of users and the growth of data volume, realizing the smooth expansion of the system, meeting the storage requirements of large - scale elevator control systems, and adapting to the application requirements in different scenarios.

[0051] The user management module is used to perform operations such as adding, deleting, modifying, and authorizing the user's biometric information, and at the same time records the user's usage permissions and access records for the refined management and security audit of the elevator's use, ensuring the reasonable allocation and safe use of elevator resources. The user management module can detailedly record the user's usage permissions and access records for each use of the elevator, such as usage time, floors reached, etc., providing strong support for the refined management and security audit of the elevator.

[0052] The information recognition module compares and analyzes the real - time biometric information obtained by the information acquisition module with the pre - entered user biometric data in the storage module. By using image processing, feature extraction, and pattern recognition algorithms, it accurately matches the features such as the texture pattern of the palmprint, the blood vessel distribution of the palmar vein, and the iris texture of the eye pupil, so as to quickly and accurately determine the user's identity. If the match is successful, it sends a start signal to the elevator control system to allow the user to use the elevator. The information recognition module combines multiple biometric technologies, can extract the unique biometric features of users from different angles and levels, greatly improves the accuracy of identity recognition, effectively prevents illegal intrusion and unauthorized use of the elevator, and ensures the safety of elevator use.

[0053] This embodiment also discloses a hierarchical control method for an elevator with palmprint, palmar vein, and eye pupil recognition functions. By pre - entering a security level into the control system through the user management module, the number of biometric information matches required for the system to start the elevator is adjusted. The control method and control rules are as follows:

[0054] 1. Pre - entered security levels and information: Management personnel pre - enter the biometric information of different users in the elevator control system, including palmprint, palm vein, and eye pupil information, and set corresponding security levels for each user or user group, such as high, medium, and low levels.

[0055] 2. Users using the elevator: When a user arrives at the elevator hall, biometric information is first collected through the palmprint collection device, palm vein collection device, and eye pupil image collection device installed in front of the elevator door.

[0056] 3. Information identification and comparison: The collected biometric information is sent to the information identification module and compared with the pre - entered information in the storage module. The system will judge whether the number of matching biometric information meets the requirements of the level according to the preset security level rules:

[0057] 3 - 1. High security level: If the security level is set to high, the elevator will start only after the palmprint information, palm vein information, and eye pupil information all match. This setting is applicable to places with extremely high security requirements, such as financial institutions, important confidential departments, etc., to ensure that only authorized personnel who have passed multiple biometric verifications can use the elevator.

[0058] 3 - 2. Medium security level: When the security level is medium, the elevator can start if two of the palmprint information, palm vein information, and eye pupil information match. It is applicable to general commercial office places, government agencies, etc. Under the premise of ensuring a certain level of security, it can also meet the relatively convenient use requirements.

[0059] 3 - 3. Low security level: Under the low - security - level setting, the elevator can start as long as one of the palmprint information, palm vein information, and eye pupil information matches successfully. This level is applicable to public areas with relatively low security requirements, such as ordinary residential communities, hotels, etc., to facilitate users to use the elevator quickly.

[0060] 4. Elevator start and operation: Once the matching conditions of the corresponding security level are met, the elevator control system will send a start signal, and the elevator will start running to send the user to the target floor.

[0061] The above - mentioned control method can effectively improve security. By setting different security levels and the corresponding requirements for the number of matching biometric information, it can effectively prevent unauthorized personnel from using the elevator and reduce security risks. Especially in the high - security - level mode, the matching of multiple biometric information greatly increases the difficulty of forgery and illegal intrusion, ensuring the security of the areas associated with the elevator.

[0062] The control method of this embodiment has strong flexibility and can be flexibly configured according to different application scenarios and security requirements. For places with different security requirements, only the security level setting needs to be adjusted, and there is no need to replace the entire elevator control system, which can meet the diverse needs of various buildings and user groups.

[0063] This method can balance convenience and security. On the premise of ensuring safety, the settings of low and medium security levels also take into account the convenience of use. In some places where the security requirements are not particularly high, users can quickly use the elevator without going through cumbersome multiple biometric verifications, improving the use efficiency of the elevator and reducing the waiting time of users.

[0064] In addition, this method combines three biometric technologies of palmprint, palm vein and pupil. By utilizing the complementarity of multiple biometric features, it reduces the false recognition rate that may occur in a single recognition technology, improves the accuracy and reliability of identity recognition, and further ensures the security and effectiveness of elevator control.

[0065] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
