Investigation and Application of Smart Door Locks based on Bluetooth Control Technology

Recent studies show the design of smart door locks is mainly based on CPU card technology. However, this design is costly with poor confidentiality. In this paper, a new method of smart door locks which can be controlled through Bluetooth is proposed. The first process of the method is an overall design of smart door locks based on Bluetooth control, including central controller, door locks controller, Bluetooth communication module and system keyboard. The second process is hardware design of smart door locks, which mainly adopts Bluetooth serial port module, drive motor, limit switch and current detection module of smart door locks system and STC15F2K32S2 single chip microcomputer. The last process is software design. The software consists of the control software of smart door locks and client Bluetooth software for mobile intelligent terminal. Experiments show that this new method of smart door locks based on Bluetooth control is more economical, safer, more flexible, and more efficient.
