Question

4-1: They have asked you to design a controller that does the following: If the nozzle handle switch is depressed and the pump pressure sensor indicates low pressure, then allow gas to be pumped. If the pump pressure sensor indicates high pressure then turn-off the pump. (The system clock pulses every one second and you may assume that once the pump shuts off, the pump pressure returns to normal within one second.) Once the pressure returns to normal, allow the pump to be controlled again by the nozzle handle switch. If the pump pressure sensor indicates high pressure a second time, your design will permanently shut down the pump until reset by gas station personnel. (Note that there are two inputs to your synchronous machine: the nozzle handle switch position, and the pump pressure sensor indicator. Your synchronous machine has one output that controls the pump.)

Design #1 (Mealy machine):

Create a state definition table here that describes in plain English what each state in your machine means and what binary values you have assigned to represent each state. Create tables here to display your state diagrams, state transition tables and Karnaugh maps used in your design process.

Also looking to what the circuit will look like. Please!

Explanation / Answer

Solution:

From the concept of Flip Flops , counters using those we can control the system for the number of times pump pressure sensor indicates high pressure.
