Automatic Chocolate vending machine (AVCM)
Embedded systems are integrated systems. Each system is designed for a specific functionality. They contain integrated hardware pieces with software loaded in their memories. Simple examples are cell phones, Smart cards, DVD players, Digital cameras, Robotics in Assembly line, Control systems used in automobiles, Guided Missiles, Satellites, Automatic chocolate vending machines the list is unending.
Thus, an embedded system is a processing system, consisting of an integration of designed hardware and software components, to fulfill desired functionality. Below, an embedded system is given along with their functionalities.
The term automation refer reduction in human works. In a shopping malls, it is difficult to manage the shop with chocolates. Dealers have to spend more time for less cost product like chocolates. For that an automatic chocolate vending machine is necessary. The machine already in malls are working based on weight comparison. In addition to that we are going to introduce a comparison on coin with image processing. Each coin will be compared with already stored images. In the previous method there is a possibilities of inserting any metals equal to that of a coin s weight.By including this technique, these malpractices can be eliminated.
An RTOS has to schedule the buying tasks from start to finish. Let C/OS-II be the RTOS used in ACVM. The machine has a slot for inserting the coin.
There is a slot into which a child (buyer) inserts the coins for buying a chocolate. The chocolate costs Rs. 8. A coin can be in one of the three possible denominations: Rs. 1, 2 and 5. Whenever a coin is inserted, a mechanical system directs each coin to its appropriate port, Port_1, Port_2 and Port_5. The machine should have an LCD display matrix as User Interface . Let the interface be called Port_Display. It displays the message strings in three lines. It should have a bowl from where the buyer collects the chocolate through a port for delivery. Let this port be called Port_Deliver. All ports, Port_Deliver, Port_Refund and Port_Excess Refund communicate to Port_Collect. This port is a common mechanical interface to the bowl. An RTOS has to schedule the processes (tasks) for buying from start to finish. It should also be possible to reprogram the codes and relocation of the codes.
