Abstract:
Combining the traditional mechanical lock cylinder with 1-wire electronic address chip,and based on the technologies of PIC microcontroller and 433 MHz wireless transmission,the paper introduces a composite design of smart lock cylinder,which integrates the benefits of the mechanical lock with digital system,and realize on-site and remote alarms.The principles of the mechanical structure,digital control method and 1-wire bus based cryptographical management of the smart lock cylinder are introduced,and the hardware frame and software flowchart of the system are also provided.The experiments prove that the lock cylinder can work in a wide operating voltage range with improved reliability,and that due to the same appearance and dimension of the traditional mechanical lock cylinder,the smart lock cylinder can be installed into lock handle easily to complete cylinder upgrade.
