Design of Management System in Granary

*****

Abstract

With the rapid development of science and technology, microcomputer technology and automatic detection technology have been widely applied in the various sectors of society.

The monolithic integrated circuit technology and automatic detection technology are mainly used in application design of granary management system in this paper. With51 single chip microcomputer working as control center, the design of granary management system is mainly composed of DH11 temperature, humidity sensor, a wireless receiving module, the clock chip, LCD, memory chips and so on. Wireless receiving module will detect the real-time temperature and humidity of the granary and send it to the host and then transmits the data to the computer, so the system can be detected according to the circumstances and settings corresponding control, which will ensure that the granary provide a good environment.

The selection of design scheme, the hardware compositions, the working principle, the design of software, the debugging and testing of the granary management system are introduced in detail in this paper. And it is showed in test that the system can achieve the predetermined functions and the performance indicators all meet the requirements of this design.
