[摘要]
目前，可编程序控制器已广泛地应用到各个工业领域，在日本已将发展应用可编程序控制器作为其基本国策之一。目前，国内市场上大量充斥着美国AB、GE，日本三菱、松下、欧姆龙，欧洲西门子等国外产品，极少看见国产品牌。本项目的特色就是采用最新的AVR单片机，定义国产品牌的新型可编程序控制器(PLC)。争取使国产化新型可编程序控制器在市场上占有一席之地。

PLC is widely used in many industried areas at present.Japan has
Established the use of PLC as one of its basic policies.
Now,domestic market is occupied by various kinds of forigen electronic products,such as AB and GE of America,Mitsubilish,Panasonic and LOGO from Japan,Siemens in Germany and so on.
The unique character of this project is by using the latest AVR SCM to define the new PLC produced in our country.By this way,domestic new PLC can be expected to have its own position in the market.
