Automatic Washing Machine and Automatic Gear Shifting Model Using State Flow

TARGET:-

1. To make an automatic Washing machine using state flow sequence.
2. To make a Gear Shifting logic using Sumilink Chart.

OBJECTIVE:-

1. in the automatic washing machine, the given conditions are:-
   • If the power supply is available then, the system is activated.
   • If the water supply is not available then, stop the process & indicate through the LED.
   • Soaking time should be 200sec followed by washing time 100sec.
   • Then rinsing happens for 20sec then the dryer runs for 50sec.
   • After all the process is finished then turn on the finished LED.
2. for the gear shifting model:-

   throttle Range (Kmph)	0-15	16-25	26-40	41-60	61-above
   Gear Shift	1	2	3	4	5

BLOCKS REQUIRED FOR THIS:-

1. Washing Machine:

   Name	Quantities
   Chart	7
   Junction Point	1
   Constant	2
   Mux	1(5Port)
   Display	1(5Port)
   Lamp	7
   Slider Switch	2
   Masking	3

2. Gear Shifting:

   Name	Quantities
   Chart	1
   Junction Point	1
   Constant	2
   Slider	1
   Half Gause	1
   Scope	1(2Ports)
   Toggle Switch	1
   Masking	3
   Lamp	7
   Go To	1
   From	1

THEORY:-

1. Washing Machine: This is a common machine which is been used since a long years ago for washing clothes, but now this is automatic mostly but in earlier days those wear used to be manual or we can say semi-automatic, nowadays these machine are been advanced and are automatic, this machine now can complete all the process by themselves no need to worry only you need power, water supply, detergent and your dirty clothes. And you will get your clean. But in semi-automatic, you have to but manually your clothes to the dryer section as they wear used to have two components.
2. Gear Shifting: Nowadays it is a common thing while you buy a car every one gets an automatic gear shifting technology because it is a hassle-free and no need to change the gear and press the clutch anymore,

DIAGRAM:-

PROCEDURE:-

1. Washing Machine: it has two processes one states flow graph and the next is the circuit diagram,
   • State flow
   • Add the 7 chart blocks.
   • Connect the supply with the condition as high to the water block.
   • Connect the water block with the condition as high to the next block, as it is a soaking block we have to state the condition for entry=0, exit=1.
   • Connect the soaking block to the next block which will come after 200sec is passed, as it is a washing block we have to state the condition for entry=0, exit=1.
   • Connect the washing block to the nested block which will come after 100sec is passed, as it is a rinsing block we have to state the condition for entry=0, exit =1.
   • Connect the rinsing block to the next block which will come after 20sec is passed, as it is a drying block we have to state the condition for entry=0, exit=1.
   • Connect the drying block to the finished block which will come after the drying process is over i.e., 50 sec.
   • Connect a junction point and from the water, block connect it to the junction with a condition water==0 and also connect a supply block to the junction with the same condition supply==0.
   • Main Circuit
   • As we will get 2 inputs and 5 outputs now.
   • Connect a constant having value '1' and connect a slidder switch with the value as '0' in low and '1' as high.
   • Connect a constant having value '1' and connect another slidder switch with it the value as '0' in low and '1' as high.
   • Connect 7 lamps 2 in the input supply and water, other 5 lamps are connected to soak, wash, rinse, dry and completed.
   • Turn all the lamp as green in '1' as it denotes the high and 2 inputs red on the '0' as it shows they are not available.
   • Connect a mux having 75 ports and connect each output to the mux and add a display at the output end as it will show all the value at once so, we don't need to connect 5 display at a time.
2. Gear Shift: it has also two processes one states flow graph and the next is the circuit diagram,
   • State Flow
   • Add 7 chart blocks.
   • Connect the ignition block with the neutral block as high, as it is a neural block we have to state the entry with gear '0'.
   • Connect the neutral block with the next block gear_1 block with the condition as the speed>=0 and speed<=0 in vice versa condition, as it is a neutral block we have to state the entry with gear '0'.
   • Connect the gear_1 block with the next block gear_2 block with the condition as the speed>=15 and speed<=15 in vice versa condition, as it is a gear_1 block we have to state the entry with gear '1'.
   • Connect the gear_2 block with the next block gear_3 block with the condition as the speed>=25 and speed<=25 in vice versa condition, as it is a gear_2 block we have to state the entry with gear '2'.
   • Connect the gear_3 block with the next block gear_4 block with the condition as the speed>=40 and speed<=40 in vice versa condition, as it is a gear_3 block we have to state the entry with gear '3'.
   • Connect the gear_4 block with the next block gear_5 block with the condition as the speed>=60 and speed<=60 in vice versa condition, as it is a gear_4 block we have to state the entry with gear '4'.
   • Connect the gear_5 block with the condition as the speed>=60.
   • Connect a junction block with a condition as low from the ignition.
   • Circuit Diagram(Fixed throttle)
   • As we will get 2 inputs and 1 output now.
   • Connect a constant having value'1' and connect a toggle switch with the value as '0' in low and '1' as high.
   • Build a random Signal from the signal builder and connect the signal builder with the throttle port, connect a go-to block for further use and the connect half gauge meter with the signal builder which will show us the throttle.
   • Connect a Scope from the output of the chart block and also connect a from block which is connected to the throttle, this will help in analysing the output and the input.
   • Connect 7 lamps 2 for the speed and the ignition, and each for the gears with the value.
   • Circuit Diagram(Speed changes)
   • Connect a constant having value'1' and connect a toggle switch with the value as '0' in low and '1' as high.
   • Connect a constant with value as '1', connect a slider gain with the constant, connect a go-to block for further use and the connect half gauge meter with the signal builder which will show us the throttle speed.
   • Connect a Scope from the output of the chart block and also connect a from block which is connected to the throttle, this will help in analysing the output and the input.
   • Connect 7 lamps 2 for the speed and the ignition, and each for the gears with the value.

OBSERVATION:-

1. Washing Machine:
2. Gear Shift:

CONCLUSION:-

1. Washing Machine: We have observed that all the condition is been satisfied and the state flow works completely fine, and we get the output as we require and in the last when the task is completed then all the light lit up and show us that the task is been completed
2. Gear Shift: we have observed that in different speed the gear shifting works as per the condition, and we get the square wave as output we required.
