With the continuous development of the microprocessor technology and industry automation level,the technology of microprocessor test has been widely spread and applied.This technology was based on modern test theory and provided a kind of fire-new and effective control method in application of industry control, household appliances and instrument intelligence, it has prodigious practical use and prospect.
In this paper, according to the character of environment test in graindepot, we applied modern theory to realize auto-test to temperature and humidity. We accomplished the software and hardware design of the whole test system finally.
In the first chapter, the paper introduced simply the background and development condition of auto-test system in grand put in graindepot forward the research subject. In the second chapter, this paper introduced hardware design of system. In the third chapter,, the paper introduced software design of system. Finally, several pieces of suggestions were put to improve the whole system.
