Parking Operation:
Firstly there should be a parking slot where the car can be kept and where this system can be installed. The slot is supposed to have a gate. There should be a switch to open the gate by making the switch ON. At first the owner of the car opens the gate of the parking slot then he places the car inside the slot. The system is such that infrared sensors will be placed at the end of the slot, which will be sensing the presence of the car. When the owner of the car parks his car then an alarm is raised indicating the proper insertion of the car in the parking slot. Then while the car is properly inserted in the slot, the gate is closed automatically. The system is designed as such there is a time interval for which the car can be kept and there is also an automatic charging scheme so that the owner of the parking slot is not deprived of its actual profits. For design purpose it has been decided that the system will operate only for a rupee five coin and not for any other coin of same, lesser or bigger size. A novel mechanical design has been used which identifies the impact force of the object
dropped from a specific height, there by operating a lever to swing to give a signal to the
electronic system. So keeping in mind of the time for which the owner will be placing the car in the slot, he will have to put that number of coins. There should be one display in which the number of coins inserted can be seen. For each coin inserted a counter will count from zero to fifty nine i.e. a duration of one minute (the time duration is taken one minute for demonstration purpose). Which means for a five rupee coin the owner of the car will be given a time period of one minute. This time period of one minute can be increased or decreased as per the requirement of the authority. So if the car has to be parked for five minutes then the owner should drop five five-rupee coins one by one through the drop pipe which has got one lever to activate the circuit. This is the total parking operation as mentioned above.
Count-Up Sequence:
For each coin dropped the coin counter will count up one, and when the allotted time period allotted for each coin is over, the coin counter will count one down. This will continue and will count perfectly for each and every coin dropped.
Taking Out Operation Of The Car:
While taking out the car from the parking slot there may be two case, firstly when the owner comes within the allotted time to take out his car, secondly if the owner of the car comes after his allotted time. We have solved this problem efficiently. Firstly when the owner comes within the allotted time then he can take out the car by opening the gate of the parking slot by applying the switch provided outside the parking slot. In the second case when the owner comes late to take out his car then he cannot take out his car by opening the gate using the switch as the switch is disabled by the system .The owner now has to face penalty as he blocked the parking slot by keeping his car for more than the allotted time. Thus the owner has to drop again a coins of five-rupee to enable the circuit and then he
can take out his car.A further planning can be implemented in which the counter counting the number of coins will count down after becoming zero, if the owner fails to appear in the scheduled time. Thus the owner will have to drop coins one by one to make the counter zero again to enable the circuit and then he can take out the car. In this way the company can make money for the extra time the owner has parked the car and all this is done automatically through the system and no individual is required to keep track of it.
