For The Financial Sector Of Research And Application Of A New Generation Of Intelligent Combination Lock System

Safe locks is ensure the safety of the financial field,the research of electronic combination lock is to improve the safety of the lock.Because electronic combination lock with large amount of key and can cooperate with mechanical lock,it is not easy to be copied,etc,thus can greatly improve the security,electronic lock can also give up mechanical keys,these advantages is the root of electronic lock become popular.The original mechanical locks in the financial sector have can't meet current demand for safety and reliability,therefore need a new product to upgrade,at the same time to improve the security and meet the requirements of the financial industry at informatization and intelligent.This topic is produced in this background,through the investigation and research of the market demand,on the application of the current domestic and foreign financial industry locks carried on the thorough analysis,considering the advantages and disadvantages of the existing locks,designed a new combination lock system to meet the requirements of the financial sector.The lock system in the aspect of hardware to complete the combination lock body,lock body controller,the design of intelligent terminal equipment.Software to complete the combination lock body control software design,the design of the intelligent terminal software,the software design of the encryption algorithm,computer integrated management system software design.In the lock body and intelligent terminal,Chose Cortex-M3 series ARM chips of Cypress company as the main controller,and chose this company's power supply chip MB39A123 for lock body and the intelligent terminal as the power processing chip,also uses the current relatively mature fingerprint identification of biological technology,used to verify the operator permissions,between the lock body and intelligent terminals used the WIFI signal communication,lock body and the intelligent terminal in communication with upper machine adopts USB interface,lock body power supply adopts three 1.5 V AA batteries,intelligent terminal powered by 3.7 V rechargeable lithium batteries.Software adopts the modular design method,the lock body and intelligent terminal software developed in Keil environment,PC software developed in Visual Studio 2008 environment.In the PC and the lock body uses the same secret encryption algorithm of SM3 national standard encryption algorithm to generate the open and close codes,in order to make sure the password authentication to go through.New combination lock system applicable to financial institutions,such as automatic teller machines,bank branch and vault safe and places of higher security level,to improve the work efficiency and security are greatly,has already begun in the domestic and foreign financial institutions to get promotion.
