2.  Background  Problem Definition  Proposed Solution  Design Objectives  Implementation and Testing  Budget Estimate  Project Timeline

3.  Project54  Integrates police devices into one interface 1.In-cruiser computer 2.Controller Area Network (CAN) 3.Devices

4.  System Benefits  Access to motor vehicle and license records  Individual device control  Voice activated commands

5.  System operation is in-car only  Need for out-of-car operation  Photos  License scanning and records  Device Operation  Out-of-car operation requires wireless connectivity

6.  Microcontroller-based interface  Receives wireless data from Personal Digital Assistant (PDA)  Transfers wireless data to Project54 Device Network  Wireless communication between PDA and Project54 device network

7.  Design two interfaces  Wireless ▪ Two connections to receive wireless data ▪ Wi-Fi 1.Long range wireless connections ▪ Bluetooth 1.Short range wireless connections  Wired ▪ RS232 Serial 1.Transmit data from MCU to Project54 device network

8. System Hardware Diagram

9.  Construction  Wi-Fi and Bluetooth shields ▪ Buy pre-assembled versions 1.Hardware too difficult to fabricate by hand  RS232 shield ▪ Hand Fabrication 1.Few components 2.Simple Circuitry

10.  Software  Wireless connection ▪ Code to receive and store Wi-Fi data ▪ Code to receive and store Bluetooth data  Wired serial connection ▪ Code to interpret received data, send commands  Software must be fast, accurate  Minimize data delay  Correct data transmission and reception

11.  Testing of individual connections  Wi-Fi hardware and software  Bluetooth hardware and software  RS-232 hardware and software Bluetooth Connection Wi-Fi Connection RS232 Connection
