automated carwash system

AUTOMATED CAR WASH BY- Koyya Shiva Karthik Reddy

Dept. Of Electrical and Microelectronics

Rochester Institute of Technology

INRTODUCTION

As a part of the course requirement an automated car wash system was designed On RSLOGICS

5000 taking into consideration scenarios which were close enough to real world car wash

system. The entire system was divided into two zones namely zone 1 which included

operations pre-soak, foam applicator and scrubbing and zone two had operations rinsing, wax

applicator and drying, both the zone were implemented on two different controllers which

communicated via Ethernet . The program was designed such that it can handle cars arriving at

random interval and can also speed up the process of all operations in both the zones if the

waiting queue was long. Most of the logics were written in ladder digrams.

INPUT AND OUTPUTS USE TO SIMULATE THE OPERATIONS IN ZONES

OUTPUTS Type Zone1 use Zone2 use

Cylinder Entrance door Exit door

Light Pre-soak operation Wax applicator

Dc motor Scrubbing operation Rinse

Fan Foam applicator Dryer

Stepper motor Car mover Car mover

DISPLAY BCD display Cars in queue waiting Cars washed

INPUTS Selector switch System start

Cylinder sensors Indicators Indicators

UDT: UDT was made to transfer data between the zones (produced and consumed tags)

ZONE1_STATUS BOOL

SYSTEM_STATUS BOOL

MODE DINT (1 OR 2)

AOI: A random number generator was used to generate cars at random interval

Structured text: Seq_operation in zone 2

ZONE 1 FLOW

Once the system was started cars were generated at random intervals and the numbers of cars

in the queue were checked to determine the mode of operation (mode 1 or mode 2 indicating

normal or fast operation respectively) once the mode was decided the cars was taken in and

the sequence of operations were performed and once all the operations in zone 1 were over

zone1 waited for a indicator from zone 2 saying its ready before moving cars to zone2.

ZONE 2 FLOW

Once the car was moved to zone to it would carry out sequence of operations based on the

mode received from zone 1 , and once the operations of zone 1 are over it moves the car out of

the car wash and indicates it ready to except new car in into the zone.

CHALLENGES

The project was basically simple but the main problem I faced was to understand how the scan

in the program goes on, when there is a control shift from main to subroutine and as a result of

this problem I wasnt able to use my AOI which was random car generator as I wanted it to be

scanned only once every program but it used to be scanned continues and kept adding cars.
