Digital Counter for Storage Center Based on Microcomputer

Abstract In recent years, with the rapid development of China's logistics industry,Warehou

-sing industry is also rapidly developing followed by its pace of development。 Currently ,the technology used to solve the problem of space utilization of storage center is automated storage technology based on computer。 The technology uses the computer to control the storage and removal of the goods。The application scope of the technology is expanding day by day,and gradually penetrate into various fields such as production inventory, product allocation and warehousing logistics center, and so on。

The design is pided into seven modules, respectively they are power circuit module, reset circuit module, analog counting module, MCU control module, digital tube display circuit module, LED circuit module and alarm circuit module。Its function is to simulate the storage and removal of goods in each warehouse and judge whether the warehouse is empty, normal or full and react accordingly。

Counting function is not only used in warehouse, but also is widely used in practical production,such as products counting of assembly line。In life, counts can be used for counting car parking space in parking lot。

The paper has 26 pictures,1 table,25 references。

Key words:counter microcomputer digital tube LED buzzer
