Your control system should start and stop the conveyor belt in an appropriate manner to move the parcels from the vehicles to the storage bins. It should have a LDR based sensor solution for detecting the parcels travelling on the conveyor belt and should keep a count of how many object have dropped into a given bin. This count is to always be displayed on a 7 segment based LED display. When a bin is filled to its capacity, the conveyor belt should stop, and a Morse code message should be emitted via a buzzer. When the operator has replaced the full bin with a new, empty one, they should have a way of notifying the system of this, so that operation can continue. Design your system making use of techniques and devices covered in this module so far. You can use either a PIC18F45K20 or a PIC18F25K20 as the microcontroller in your design. Write your firmware in assembly. o Stepper motor driven conveyor belt control: Basic: The conveyor belt starts and stops moving based on the state of the bin or operator input. The motor runs at 50 RPM or more. o Advanced: As above, but with a gradual start and stop of the conveyor belt. o Detection and counting of objects on the conveyor belt: Basic: The system uses an LDR based sensing solution to correctly count objects on the conveyor belt, when they are of a certain size and moving at a particular speed. Advanced: The system is robust enough to correctly count objects of nearly any size moving at any practical speed. o Operator interface: Basic: o The operator can inform the system that a full bin has been replaced by a new one, and the conveyor belt can start moving again. As above, with the addition of a way for the operator to start, stop, pause and resume the operation of the system. o Advanced: o Bin capacity and display of the number of items in the current bin: Basic: Bin capacity is 9 items. One digit 7 segment display shows the number of items in the current bin. O Advanced: Bin capacity is 19 items. Two digit 7 segment display shows the number of items in the current bin. Morse code notification for a full bin: Basic: The system generates a Morse code message ("BIN FULL") via a Buzzer, every time a bin gets filled. Advanced: The number of full bins is counted by the system and every time a bin is full, the Morse code message is "BIN X FULL", where x is the bin number.
