parking system using pic 18f4520

This project calculates the time of entering the car to the parking and the time to go out and calculates the cost.
When a car enter the park , the IR beam between the transmitter and receiver will be disconnected. The disconnection will trigger the interrupt which will save the arrival time from RTC to the EEPROM ,
The same configuration is set at the exit .. but this time we get the time of departure and save it to the EEPROM … the we subtract the two values and Multiplication to Tariff rate and calculate the cost and show the time and the value of cost on the screen


Component
Pic18f4520
voltage regulation 7805
lcd 16x2
Real time clock(RTC)
IR sensor (transmitter & receiver)

i don't know how write the code to program the pic and simulation please help me>>>

 

[S.P.S]

is there a sensor pair for each parking slot ?.if no you should identify the vehicle otherwise the project is meaningless.
there is a text book named PIC microcontroller and embedded system by muhammad ali mazidi.it will help you.

you can use IR tranceivers... But the real problem is that you must have a tranceiver for each vehicle to be parked. Instead you can make the system to read the number board and make a database on that. For this you need some complex program but your hardware 'll be some what easier. Decide a best way of your project...
To read the number board there 'll be some special sensors available... Google it and you can get it easily...
