If a intelligent nanny machine is designed,it will bring more convenience forpeople's life.At present, the nanny machine which is on the sale in the market is almost mechanical, has a single function, and controls household appliancescan according to the setting time only through the power. This paper introduces the research backgroud of the nanny machine and uses the SCM design scheme through comparing 555 design scheme,FPGA design scheme and SCM design scheme. In this paper, the nanny machine ,which is designed through using electron technology,has many functions .It not only can control the Household appliances from time to time, but also can display time,temperature and so...
