  2. Outline • Project description • Reasons why SECO marketable • Design of mailbox • Hardware • Embedded controller: NI RIO 9626 • Other components: • Fingerprint scanner • IR detector & transmitter • Lock • Software • Labview • Cost • Summary • Possible Improvements

  3. Hardware

  4. Project Description • SECO is an electronic mailbox • The mailbox will be made from a secure material • The mailbox will have a fingerprint identification lock • Key lock will be used to override fingerprint scanner lock • An infrared transmitter and receiver will be used to detect mail • SECO will have email capabilities

  5. Design of Mailbox • Environment • Indoor environment • Weather elements were not a factor • Size • Large enough to allow at least an 8 ½” X 11” letter size paper to lay flat in the box • Small enough to accommodate many mailboxes in a common place • Fits in the mail cubicles in Broun Hall.   • Security • Made from a material that will be difficult to pry open • Marketing purposesmailbox will be made of Lexan

  17. FIM5360-LV Fingerprint Scanner

  18. FIM5360-LV Fingerprint Scanner • Does not require Universal Serial Bus (USB) connection • Has board dedicated to processing of fingerprint scans • Communicates with primary embedded controller with simple serial communications (e. g. request for authentication, registration, or deletion; successful or failed authentication indicated by single returned logic level)

  19. Block diagram of FIM5360-LV

  20. IR Detector & Transmitter

  21. IR Transistor vs. Photocell Resistor

  22. Rutherford 3510MS Electric Cabinet Lock • The lock responds to electronic signals for matching fingerprint • This lock is a compact size • Has higher force standards • More expensive lock but benefits outweighed the cost

  23. Manual Lock Override • Amico 16.5mm diameter cabinet tool box quarter turn cam lock • Consist of a cam lock and key combination • Switch is pressed triggering a high signal • Send a signal to unlock the electronic mailbox lock • key must be used to toggle the switch

  24. Software

  25. LabVIEW LabVIEWis a high level graphical programming language that allows the user to code using a flow chart rather than text.

  26. How to turn an LED on? • C program: DDRT = 0x01;// set bit 1 as output while(1){ if(sw==on) PTT_PTT1 = 1; //logic high else PTT_PTT1 = 0; //logic low }

  27. How to turn an LED on? • Labview:

  28. Cost of Project

  29. Summary • SECO will provide a secure, information-age means of improving the efficiency of standard mail and office communications.
