Design a system that shows a simplified automatic car wash system with the following operating conditions:

– Water level needs to be maintained at water level (> Lower limit and < Upper limit ) at all times to ensure the water pressure is sufficient for the wash cycle.

– 2 Possible errors:

– Water level exceeds upper limit or water level falls below lower limit

– Car move away while washing process is ongoing

– System shall stop if the water level falls out of normal range for a specific duration ( example. 30 secs)

– Green indicator will turn on when car wash is in progress(system is running) and red indicator will turn on when the system stops

– Start/ stop push button is used to turn on / off the system

– Roller and spray valve should turn on when car presence is detected and the system is running with normal water level. The washing cycle should last for 5 minutes

– Buzzer will turn on when there are errors. When the buzzer is triggered, the buzzer frequency should be programmed in such as a way that the operator can differentiate between water level errors or error caused by car moving away during the wash cycle.

– A counter is used to count the numbers of cars washed by the system.

* Assuming the water level sensor provides a 0-10V output voltage corresponsed to the water level of 0-100%.

It should include

– Information on sensors, actuator, motors, relays used in designing the system

– All wiring circuits

– Input/output table

– PLC configurations and ladder diagrams

– Any process improvement proposed/ implemented

– Database table which include the necessary data( minimum 5 data) to be uploaded to the cloud

– Suggestion of possible data analysis / monitoring for this system
