Application Of Fingerprint Recognition Technology In Anti-Theft Door

Fingerprint recognition technology is the application of biological information technology, the uniqueness of individual fingerprint, used in personal identification, to ensure the safety and reliability of the information. Fingerprint as the key, the fingerprint recognition technology to open doors and home security control combined to achieve control of the security door and uniqueness of the legality of the information, to ensure the safety of family property and personal with a wide range of application.Fingerprint Identification and lock in the drive control system, the pre-filing legal status of the fingerprint information, and through fingerprint collection stored in the SPI FLASH. When the user has access to necessary, fingerprint sensors capture the characteristics of the user fingerprint information, fingerprint analysis of eigenvalues compared to the chip to determine whether the user has access permissions. If the user has the permissions required, after the verification by the chip output control signals to drive DC motor to achieve the gate lock control; if the user does not have the appropriate permissions, verified the information will be given validation fails.This study made use of theoretical analysis and the method of combining physical, hardware and the maturity of the existing control software developed by combining the method with experimental test developed by testing the reliability and security, is the research and mechatronic systems The main measures and strategies developed.This article will fingerprint recognition technology and home security door lock drive combined to FSC7002micro-chip as the core, building a security door control system of fingerprint identification technology solutions, including fingerprint sensor, lock drive system and control, data transmission Information input and output modules; respectively each module control circuit design and analysis, clearly the system in a variety of interface circuits, signal transmission and logical relations, to ensure smooth flow of information between hardware and reliable; the VC language development tools The preparation of the system initialization, fingerprint detection, fingerprint registration, fingerprint deleted, fingerprint matching, sensor data transmission, motor control, voice control, nine control module. To achieve the read fingerprint information, analysis, identification, lock drive, information to delete, voice prompts and other functions, to meet the security door security control function requirements.Buying FSC7002microchips and optical fingerprint recognition sensor and analog lock drive mechanism to form the hardware kind, will control software into the micro-chip, the control functions on a variety of software testing and inspection, indicating that the fingerprint recognition built, lock a drive system, information input, recognition, execution and other functions and reliable fingerprint recognition to non-legally accurate and achieve the desired research goalsThis fingerprint recognition technology and security door security control of the combination of content, is the comprehensive application of mechanical and electrical integration technologies, research methods and techniques used in line with other studies of mechatronic systems with a reference value and significance.
