Vehicle Monitoring and Security System
by Ranjith | June 7th, 2009.RF UNIT
The RF section consists of an RF transmitter and an RF receiver. The RF transmitter mainly consists of a remote key that contains a code hopping encoder, HCS301 along with 2 buttons and two LEDs. The RF receiver section consists of a Low Power ASK receiver IC. The key encoder will generate the company specific “Company ID”, which will be decoded by the low power ASK receiver IC. The LEDS are used to show the status of the remote key. The two buttons provided are used for ‘entry’ and ‘exit’. When both the buttons are pressed together, the system goes into a ‘panic’ state wherein the system will turn on the siren and immobilize the vehicle in emergency condition after a 10sec delay.

POWER SUPPLY SECTION:
The power supply section consists of LM309, which is a 5V regulator fabricated on a single silicon chip. Current limiting is included to limit the peak output current to a safe value.
KEYBOARD SECTION:
Here we are making use of a 4X3 matrix keyboard. The columns are connected to an output port and the rows are connected to an input port. In this unit the keyboard is interfaced to the PIC18F722 IC with PORTB as the input port and PORTG as the output port. Pins RB2-RB5 of Port B and pins RG0-RG2 of Port G are connected to the keyboard. Pull-down resistors of 27k ohms are used.
LCD SECTION:
The LAMPEX 16101 LCD module is interfaced to the PIC18F8722 microcontroller. The data lines are connected to Port E and the control lines are connected to Port D of the PIC microcontroller. Only four of the eight data lines are used. The LCD is used in 4-bit mode with the hardware connected as follows:
- PORTE bits 0-3 are connected to the LCD data bits 4-7 (high nibble)
- PORTD bit 1 is connected to the LCD RS input (register select)
- PORTD bit 2 is connected to the LCD R/W input (Read/Write)
- PORTA bit 3 is connected to the LCD EN bit (enable)
RF SECTION:
RF TransmitterThe RF transmitter (2-button remote) mainly consists of a code hopping encoder, HCS301. S0 (pin1) and S1 (pin2) of HCS301 are connected to the two buttons, which are used as “Enter” and “Exit”. Pin 5(Vdd) is connected to +12V supply and pin8 is grounded. Pin 7 is the transmitter output. The LED is connected to pin 7.

CONCLUSION:
The outcomes of this project will be anticipated to show that it will alert unaware drivers from preventing a traffic accident, recognizing some unusual situations or gaining more response time whenever the EV (Emergency Vehicle) was approaching. Furthermore, its commercial achievements will especially be used in ITS (intelligent Transport System). It will pre-warn the involving drivers to avoid the emergencies and accidents as soon as he encounters an EV along the roadways.

I just can’t believe it how many people post spam on sites especially blogs just for the sake of some link juice. I need to stay alert all day even with fancy pluggins like spam killer… I dont want to imagine what would happen to my work if I didn’t had this kind of protection.
