Abstract

Automated warehouse is an important part of the rapid development of modern logistics system, it has to save space, reduce labor intensity, eliminate errors and improve the level of automation and warehousing management, reduce outages and improve the efficiency of logistics and many other advantages. Currently, automated warehouse to be more widely used in various industries.

This paper describes the automated warehouse based on Siemens PLCS7-200's design, including software and hardware design. This paper introduces the working principle of the automated warehouse, the hardware of the system composition, structure, principles are described and analyzed; once again used the device of the system were introduced, focusing on the preparation of the PLC program. The system realizes the function of automated warehouse material handling equipment using advanced automation, not only can automatically access the necessary goods in the warehouse, and can be connected to the warehouse beyond organic production processes, and through computer management systems and automation warehouse material handling equipment so that production logistics become an important part. S7-200 programmable controller as the core control signal input port to complete the acquisition of various arithmetic logic control and data, and then complete the realistic movement of the motor and a variety of signals through the output port. The system should be able to achieve both manual and automatic mode, the device can be controlled via the keyboard. Finally, the design of this project have learned knowledge and summarized.
