You are to design the control system for a simple metro train system. You are responsible for the doors on the train, as well as the wheel motors on the train. The train will start in a stationary state. When you have initialised the train your system will signal that the train is ready to proceed. The train will stay stationary until your system receives a proceed signal. You will then start the motors at that point. The motors have four speeds: stop, slow forward adjust speed, medium forward speed and full forward speed. When the proceed signal is removed your system will need to slow the motors to slow forward speed until you are aligned with the doors as indicated by the aligned signal. At that time you will need to stop the motors until the Current Speed input has become stationary. Once the train is stationary at the station your system will need to open the doors and signal a timer to start. When the timer has expired your system should close the doors, and signal you are ready to proceed. You will then receive a proceed signal and the whole process will repeat. The inputs to your system are: Signal Value Proceed 0 1 Aligned 0 1 Doors Open 00 X1 10 Meaning Do NOT Proceed Train May Proceed Train is NOT currently aligned with the platform doors Train is currently aligned with the platform doors Doors are closed and locked Doors are partially opened Doors are fully opened Train is stationary Train is moving at slow adjust speed Train is moving medium Train is at full speed Timer is Counting Timer is at Terminal Count and has stopped counting CurrentSpeed 00 01 10 11 TimerExpired 0 1 Your system has to drive the following outputs. You must supply a truth table, Karnaugh map and minimal sum-of-product equations for each of these outputs. Ready to Proceed Output (RTP): Ready To Proceed 0 Meaning No Yes 1 Motor Speed Output (MS01 and MSOO): MotorSpeed Meaning MS01 MSOO 0 0 Stop 0 1 Move Slow Speed 1 0 Move Medium Speed 1 1 Move Full Speed Door Control Output (DC): DoorControl O Meaning Close the Doors Open the Doors 1 Timer Enable Output (DC): TimerEnable 0 1 Meaning Reset the Timer Allow the timer to count Task You are to design the state machine and combinatorial circuitry for the train control system. Your state machine needs to keep track of the state of the doors, the state of the motor speed as well as the if the train is at a station or not. It is suggested, but not required, that the state is held in the following D flip flop groups: State of Doors (Two flip flops) Desired Motor Speed (Two flip flops) Train Global State (Three flip flops) The meanings of some of the bits in these flip flops may be as follows: State of Doors 0 0 0 1 1 0 1 1 Meaning Doors Closed Doors Opening Doors Opened Doors Closing Meaning Desired Motor Speed 0 0 0 1 1 0 1 1 Desired Stop Desired Slow Adjust Desired Medium Speed Desired Full Speed Meaning Train Global State TGSO TGS1 | TGS2 0 10 0 0 0 1 0 1 0 0 1 1 1 1 0 0 0 1 1 1 1 0 1 1 1 Questions 1. Create the state transition diagram for the entire system. 2. Assign TGS(0-3) State Values for each of the states defined. 3. Create truth tables for each of the D flip flop groups. You must include all necessary inputs to allow you to specify the change in state for each group. 4. Create Karnaugh maps for each output (Flip flop) in the groups. 5. From the Karnaugh maps create minimum Sum-Of-Products equations for your state machine. There should be one Sum-Of-Products equation for each D flip flop.
