Abstract:
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.
