The entire system consists of a set of analog ous coin mechanism, a control panel, two sets of Eddy current sensors and coin validation program. C language is used to program the chip compiler C18 series developed by Microchip. PIC chip can calculate sensing value of coins, and return through USART by showing results on computer terminals, learning through a large number of coins, which constituted into the wafer map, when the system is switched to the identification mode, the chip will judge the coins by the map, thus excluding the impact point on the map outside of the coins. Among them, we take the same system as the voltage difference between the voltage at the point of the element distribution maps, ambient temperature compensation can be constructed influence the ability to make the system more stable, able to lower the threshold value is reached with previous research. The system''s control panel can be made in the course of various commands, such as mode switching, take coins voltage range, show the number of coins, display voltage range start value, the coin shows the chip remember map data memory burned into the program memory and so on, more enhanced results of this research, the future success of commercialization possibilities.
