RESOURCE PLANNING

BLOCK DIAGRAM


EXPLANATION PROCESS OF PROJECT

Figure 1 above shows a block diagram of Locker Security Monitoring System working process. The system consists of several part, starting from inserting the password, part when the locker will open and computer received the signal if their locker been hacked.

At the inserting password part, user a insert the password by using the keypad 4 x 3 size. The PIC 16F877A will trigger the password either correct or false and give the user 5 time chance. The LCD will display the number of password every time user inserting. If the passwords are correct, the door will unlock, and locker are able to open. If the password are incorrect until 6 time, the PIC 16F877A automatically send the signal to the computer true SKXBee wireless.

At the transmitter part, when PIC 16F877A trigger the password that inserting are incorrect, PIC microcontroller will interface and send a signal to transmitter. The, tha data will encoded and transmit to the receiver by using SKXBee Wireless.At the receiver, the data that receive from the SKXBee Wireless transmitter will be decoded before sent it to the personal computer. At the personal computer, the data will be monitor and analyze by using Microsoft Visual Basic 2008 Express Edition programmed. At here, the warden are able to know which locker have been hacked.
