Bluetooth-based Passive Lock System Design

Currently, there are many electronic locks on the market, but some of lock data management systems are not perfect enough. Traditional data management system which uses wire transmission technology to manage electronic locks has some limitations. According to the problem above, a powerless lock system based on Bluetooth is designed. Powerless lock hardware is composed of powerless lock cylinder, electronic key and Bluetooth system. Powerless lock software includes management software, remote login system and mobile client login system.Besides the basic functions of regular electronic locks, the power supply and data management of the system are integrated in electronic key to achieve electromechanical control for lock cylinders. Bluetooth module is integrated in powerless lock system. Management software sets parameters and authorizes the management of powerless lock system via Bluetooth wireless transmission mode. Powerless lock management software stores the data to the database. It is convenient for powerless lock system administrators to inquire and manage the data of powerless lock system by remote login or intelligent mobile client login.This research uses Bluetooth wireless transmission mode to avoid the complexity in wire transmission and to improve the flexibility and the convenience of the system. This system is combined with the technology of electronic, wireless transmission, database management, network and mobile terminal. On the basis of realizing the function of unlocking, system makes great convenience to the inquiry and management of the powerless lock data, broadening the scope of application of the lock management system. System with the advantages of low power consumption, stability, security, utility and convenient data management, has application potential in residence, office, field work, and so on.
