Question

please help me create a mealy machine for the following situation. pleas include a state definition table, a detailed state diagram with eveything labbeled, a transition table and k maps along with a working schematic.

Depending on the application you have to decide whether you have to synchronize the outputs of the Mealy machine or not. You can use either D flip flops or J-K flip flops for your designs. Mixing different types of flip flops with different trigger edge sensitivity is possible but not recommended. Note that two designs which differ by only the type of flip flop (e.g., J-K vs. D) or number of states (i.e., changing the type of FF or inserting more unnecessary states) is not considered conceptually different.

The Clean Laundry Company (CLC) is interested in reducing the risk of personal injury to their customers while operating their washing machine. When a customer wants to open the machine’s door, the machine should stop and the drum (motor) should come to a standstill before the door is allowed to open. Otherwise, the customer might get injured. The company installed a switch that the customer activates to indicate they are requesting to open the door. They also installed an electromechanical lock on the door that keeps the door locked. Usually, it would be sufficient to unlock the door when the power to the motor is switched off. But since the motor doesn’t stop immediately, the company installed a sensor that senses the motor’s rotation. Only when this sensor indicates that the motor has stopped, the door can be unlocked. Your task is to design a controller that releases the lock once the door is safe to open.

The controller should do the following: Normally, the machine is on where the motor is rotating in the normal washing cycle and the door is locked. If, in the middle of the cycle, the customer activates the door switch because of a need to open the door, the controller should power off the motor so that it comes to a halt. However, since it doesn’t stop immediately, the lock should remain engaged until the motor comes to a complete stop. In addition to addressing the customer safety issue, this time gives the customer the opportunity to deactivate the door switch in case they change their mind and want the machine to continue the cycle that was interrupted. However, once the rotation sensor gives a 0 signal indicating that the motor has stopped while the door switch is active, the lock should unlock and the electric current supply to the motor should remain off. At this point, no matter what the customer does, the lock should NEVER lock back again NOR should the motor be able to rotate again. If the customer needs the motor to return to normal operation, they need to call the laundry attendant to reset the controller via a switch that the customer does not have access to.

Note that there are two inputs to your controller: the rotation sensor (R, where R=1 means the motor is rotating) and the door switch (S, where S=1 means the user is requesting to open the door). Your controller has two outputs that control the washing machine: the electric power output (P, where P=1 means the power is powering the motor) and the door lock output (L, where L=1 means the door is locked).

ive already posted this question and got a schematic that didnt work when it was built which is below please ether tell me whats wrong with it or start from scratch.. thank you!

Explanation / Answer

All the procedure what you have followed is correct but while coming to schematic implematation it seems instead of OR gate in reset you have used AND gate which will side track our normal functionality.
