Week - 4
AIM: Implement controlled logic of a washing machine using a Stateflow as per giving sequence
> if the power supply is available in the system grts activated.
>if the water supply is not available ,stop the process &indicate through LED
>soaking time should be 200 s followed by washing time 100 s
>Then rinsing happens for next 20 sec & dryer runs for 50 s
After all the processes have completed turn on the LED.
WORKING PRINCIPLE OF THE WASHING MACHINE :
MACHINE :
Washing machine by spinning at 800-1600 rpm helps scope and dirt with it to leave the surface of the cloth via
centrifugal force and into outlet pipes hence utilizing centrifugation to both clean and partially dry the cloths loaded in it.
thus the processes are the electrically connected and controlled such as the drum,value ,pump motor and heating .the value open again and the dirty water dreain out of the drums. the pump get rid of the water .
The value lets clean water into the drums .
SOAKING :
it is used to dip clothes in detergent water to remov dirt from the clothes .in this function costmer need to soak from a panl soak
This function available with wash time in a 42 min of a washing 27 min is a soak are min machine will wash the clothes .
RINSING :
The dirty soapy water is a drained , then the washing machine refilled and your clothes are a rewashed in a clean water .
spain all the water is drained completely , then your clothes are spun very fast and excess water is removed thank to centrifugal force
DEYER :
They work by pushing warms dry air throgh your wet washing to extract your moisture then cooling the now humid air in a heat exchenger to condenced the moisture
CONTROLLOGIC OF A WASHING MACHINE :
it cheaks for the extent of dirt and grease, the amount af a sope and water to add , direction of a spin , and so on
the machine rebalaces washing load to ensure correct spinning speed if an imbalance is a detected even distribution
of a washing laod reduced sainning noise
Two inputs are given for the power and water supply once the input are given output are displiayed by the flow chart as per the given sequence the system are obsarved from some time than it is cheaked and the process is completed by blue light as displayed
Q 2 Make a Simulink chart for a gear shifting logic as per the below condition.
speed range (kmph) gear
0 to 15 1
16 to 25 2
26 to 40 3
41 to 60 4
above 61 5
Give speed input while that simulation is running and display the gear number.
Q 1
> Model of gear shift in a simulink :
flow chart :
Explanation :
To create, a Simulink model of a gear shift creates a state flow chart and start with the gearbox
when the gear first case speed limit is 15 and less than 15 then the display show the accurate value as per constant
and same as gear 2 case as well as gear 5 at the speed limit of 60 and less than 60
when the speed is accelerated with the help of a slider
speed 0 to 15
when the speed 15 to 25
when the speed is 25 to 40
when the speed is 40 to 60
