Wireless electronic code locking system

Wireless electronic code locking system for industrial applications

Security is a prime concern in our day-today life. Everyone wants to be as much secure as possible. An access control over devices forms a vital page link in a security chain. The project deals with a design of a simple microcontroller based system as digital lock for Devices. This system can be a control system that allows only authorized persons to access switching; the system is fully controlled by the 8 bit microcontroller AT89C51 which has internal ROM for the program memory. The pre-defined password is stored in the microcontroller.

Existing System:
Current system consists of wired device control, and it’s an unsafe procedure where any foreign body can tamper the wire physically, existing process is still far away from flaw.

Proposed System:
We are making use of RF signal for secure processing in use for safety purpose so it will be free of physical errors and it will lead us to proper communication. The keypad is provided so that the password can be entered through it. Once the key is pressed, the microcontroller at the transmitter part detects that and transmits that through the RF signal. The receiver waits for transmitter to transmit the key press signal four times. Then according to the received data it process upon it and if it finds correct password then device is unlocks else alarm go on. This will lead to a significant development in the wireless device locking technology.
