基于PIC单片机的无源锁系统设计

基于PIC微功耗单片机,设计了一套由无源锁头、电子钥匙、中心管理系统平台组成的无源锁系统.系统结合了智能锁芯与机械锁芯的优点,将系统供电模块集成在电子钥匙中,实现锁头的无源管理.介绍了无源锁系统的工作原理及机械控制,给出了硬件设计和软件流程图.系统中无源锁头和电子钥匙均可记录开锁事件,中心管理系统平台实现对无源锁头和电子钥匙的参数设置,对钥匙进行授权和数据库管理.本设计解决了野外环境中电子锁具的供电问题,拓宽了电子钥匙应用范围,在住宅、办公和野外等应用中具有推广价值.

Powerless Lock System Design Using PIC Microcontroller

With the low-power PIC microcontroller,a powerless lock system is designed,composing of powerless lock cylinder, electronic key and center managerial system platform. 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. The working principle and the mechanical control of the powerless lock system are introduced with hardware design and software flowchart. In the system,the data of unlocking events are recorded in the powerless lock cylinder and electronic key. The parameter setting of lock cylinder and the authorization of electronic key as well as the database processing are performed by the center management platform. This design solves the key problem power supply for electronic locks in wild environment, providing the broadened application potential in residence,office,field work,and so on.
