c program for automatic car parking indicator using microcontroller 8051
This system will indicate empty and filled car parking slots at the entry. Now a days Car parking at shopping malls and markets is becoming a big issue and is causing to traffic jam. To avoid this problem we are designing this system to indicate empty slots and filled slots, so that a car driving person can directly take his car to that particular empty slot. we will indicate the slot state by LEDs and also in LCD screen. we will use IR sensors to sense the presence of car in the slot.
Working: when a car enter into a empty slot the photo detector output will become '1', this will change the state of the slot to filled, otherwise it is remained in empty state only. like wise all the slots are detected by IR sensors.
Now days in many multiplex systems there is a severe problem for car parking systems. There are many lanes for car parking, so to park a car one has to look for the all lanes. Moreover there is a lot of men labor involved for this process for which there is lot of investment. So the need is to develop a system which indicates directly which parking slot is vacant in any lane. The project involves a system including infrared transmitter and receiver in every lane and a LED & LCD display outside the car parking gate. So the person entering parking area can view the LED display and can decide which lane to enter so as to park the car.
Conventionally, car parking systems does not have any intelligent monitoring system. Parking lots are monitored by human beings. All vehicles enter into the parking and waste time for searching for parking slot. Sometimes it creates blockage. Condition become worse when there are multiple parking lanes and each lane have multiple parking slots. Use of automated system for car parking monitoring will reduce the human efforts. Display unit is installed on entrance of parking lot which will show LEDs for all Parking slot and for all parking lanes. Empty slot is indicated by the respective glowing LED.
