Abstract :It has many kinds of method to realize the viing to answer first function ,may select the method which is the ear2

lier period of analogous circuit ,the digital circuit or the simulation and the digital circuit unifies. In recent years along with the

technical rapid development ,the single chip application is moving towards thoroughly ,at the same time leading the traditional

control examination to change with each new day the update. This article introduces a kind of single chip technology and nine

groups multi purpose intelligence competitions viing to answer first the C language programming using the microcomputer

chip as the core part which the logical control and the signal produces which but designs.

Keywords :PLC ;single chip ;viing to answer first ;design
