The Realisation Of Seed Coating Machine Control Part Based On LPC2131

Since the 1980s coating technology began to be promotion in our country, and it lasted about 30. Now the use of seed coating technology has become a trend. But now Seed coating technology still can not meet the needs of modern agriculture development. So Development of a set of stable and efficient seed coating machine has a very high social and economic benefits.First the coating machine control technology status and the problems being introduced in this thesis, and then propos soma unsolved problems. This Subject is used to build a Agricultural Seed Coating Machine Control System, then the hardware development platform and related software are detailed designed. In this thesis Embedded chips LPC2131 of Philips Company is introduced, and expanded IO controller,AD sampling module,Data Communication Module,Keyboard Input Module,The digital output module and Alarm Module. In the paper real-time operating system and transplantation and presented. Finally cooding the source code, for example: programme tasks of real-time operating system and main control tesk for running the system.
