Description

Technical Field

[0001] The present invention relates to the field of access control systems, and in particular to a novel building access control system based on biometric identification technology and big data technology. Background Art

[0002] The access control system is a supporting device for access control. The access control system has developed along with the automatic identification technology and has a large market. Many companies are engaged in the production and development of access control systems. At present, the access control systems researched and developed at home and abroad are mainly inductive access control systems and access control systems based on biometric technology. Among the access control systems based on biometric technology, the access control system based on fingerprint recognition is the most widely used. With the development of computer technology, the improvement of image processing and automatic identification technology, and the development of large-scale integrated circuits, the size of fingerprint recognition systems is getting smaller and smaller, and the price is constantly decreasing. It can be widely used in access control systems and many other fields. The access control system is a security system in the building automation system of intelligent buildings. As a new type of modern security management system, the access control system combines automatic identification technology with modern security management measures. Today, with the continuous growth of social wealth, the main management areas, entrances and exits, warehouses for valuables, equipment control centers, elevator entrances and other important departments in the building need to strengthen security protection measures. This requires the development of corresponding intelligent access control systems to identify the identity of the entrance and exit personnel and control the entrance and exit. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of access control systems.

[0003] The existing access control system has certain drawbacks when in use. When installing the fingerprint access control system, it is necessary to install a controller and a fingerprint reader outside the door. In this way, the control line of the door lock will be exposed outside the door and can be easily opened by others. Although the recognition method of the fingerprint access control system is very secure, the overall security of the system is still poor, which is not conducive to people's use and has brought certain adverse effects to people's use process. For this reason, we propose a new building access control system based on biometric technology and big data technology. Summary of the invention

[0040] Working principle: The present invention comprises a No. 1 access control frame 1, a No. 2 access control frame 2, a top sensing device 3, a protective mechanism 4, a control box 5, a No. 1 bottom sensing seat 6, an identifier 7, a No. 1 valve plate 8, a No. 2 valve plate 9, a No. 2 bottom reaction seat 10, a rotating rod 11, a sealing pad 12, a mounting groove body 13, a slide 14, a positioning pin groove 15, a mounting support 16, a protective outer plate 17, a slide rail 18, a positioning groove 19, a disinfection pad 20, and a positioning sticker 21. When in use, when a person passes through the passage between the No. 1 access control frame 1 and the No. 2 access control frame 2, the control box 5 and the identifier 7 perform identification control, and confirmation is performed after the identification is completed. After confirmation, the No. 1 valve plate 8 and the No. 2 valve plate 9 are opened by the rotating rod 11 to facilitate the entry and exit of personnel. The inner side of the rotating rod 11 passes through the mounting groove The body 13, the slideway 14, the mounting support 16, the slide rail 18 and one side of the second valve plate 9 are detachably connected. The rotating rod 11 and the second valve plate 9 are positioned and connected by the positioning pin groove 15 and the positioning groove 19, which is convenient for positioning and installation, convenient for maintenance and replacement. The single-chip microcomputer control scheme with AT89C2052 as the core is adopted to realize the design and implementation of the intelligent access control system, which can perform password operations, password display, password change, system unlocking, alarm system and time locking technology, among which face recognition technology, iris recognition technology and fingerprint recognition technology are designed. Face recognition technology is based on human facial features. For the input face image or video stream, it is first judged whether there is a face. If there is a face, each face is further given. The position, size and location information of each major facial organ are used to further extract the identity features contained in each face and compare them with known faces to identify the identity of each face. The iris is a ring-shaped area located between the pupil and the sclera. The texture structure of the iris is random, and its shape depends on the development of the embryo. It has high stability, and the iris can remain unchanged for decades. It is not affected by the surrounding environment except light, and has good anti-counterfeiting properties. The iris itself has regular tremors and the characteristics of scaling with changes in light intensity, which can identify forged irises such as pictures. It is easy to use, and the recognition system does not come into contact with the human body, making analysis convenient. The inherent annular characteristics of the iris provide a natural polar coordinate for reading fingerprint images and providing Taking features, saving data and comparing. At the beginning, the image of human fingerprint is read by the fingerprint reading device. After the fingerprint image is obtained, the original image needs to be preliminarily processed to make it clearer. Next, the fingerprint recognition software establishes the digital identification of the fingerprint - feature data, a one-way conversion, which can be converted from fingerprint to feature data but not from feature data to fingerprint, and two different fingerprints will not produce the same feature data. Some algorithms combine node and direction information to produce more data. These direction information indicates the relationship between each node. This data is called a template and is saved as a 1K record. Finally, the templates of the two fingerprints are compared through the computer fuzzy comparison method to calculate their similarity.Finally, the matching result of the two fingerprints is obtained. The feature face method is a face recognition method based on the KL transform. The KL transform is an optimal orthogonal transform for image compression. After the high-dimensional image space is transformed by the KL transform, a new set of orthogonal bases is obtained, and the important orthogonal bases are retained. These bases can be used to form a low-dimensional linear space. If it is assumed that the projection of the face in these low-dimensional linear spaces is separable, these projections can be used as feature vectors for recognition. This is the basic idea of ​​the feature face method. These methods require more training samples and are completely based on the statistical characteristics of the image grayscale. A more advanced algorithm for iris recognition is used. The first step is to determine the position of the iris through a precision camera 3 inches away from the eye. When the camera is aimed at the eye, the algorithm gradually The focus is on the left and right sides of the iris to determine the outer edge of the iris. This horizontal method is hindered by the eyelids. The algorithm also focuses on the inner edge of the iris and excludes the influence of eye fluid and fine tissue. The technical route adopts component technology and a three-tier application architecture model based on BROWER / APPSERVER / DBSERVER, which is implemented in a C / S manner. The external data exchange is realized through a data sharing and exchange platform to achieve reliable, stable and timely data exchange. Each application terminal uses a client browser to query and add data according to different permissions. The entire system adopts a C / S multi-layer architecture. In the architecture, clients (request information), programs (process requests) and data (operated) are isolated. The multi-layer structure is a more flexible architecture. It separates the display logic from the business logic, which means that the business code is independent and does not need to care about how and where to display. The business logic layer is in the middle layer and does not need to care about which type of client displays the data. It can also maintain relative independence from the back-end system, which is conducive to system expansion. Security is also easier to implement in a multi-layer structure because the application is isolated from the client. ,
